Is antirust paint toxic?

Question 1: What harm does antirust paint do to the body? What are the harmful substances in paints and coatings?

1, paint. Benzene compounds are mainly volatilized from paint, and benzene, toluene and xylene are indispensable solvents in paint.

2. Additives and diluents for various paints and coatings. Benzene exists in a large number of organic solvents in various building decoration materials, such as thinner such as Tianna water commonly known in decoration, and its main components are benzene, toluene and xylene.

3. Various adhesives. In particular, solvent-based adhesives still have a certain market in the decoration industry. Most of the solvents used are toluene, and the benzene content is above 30%. However, due to reasons such as price, solubility and adhesiveness, they are still adopted by some enterprises. Some sofas bought by families release a lot of benzene, mainly because of the use of adhesives with high benzene content in production.

4. Waterproof material. In particular, some waterproof coatings made of raw powder and thinner, after use 15 hours, the benzene content in indoor air exceeds the highest concentration allowed by the state 14.7 times.

5. Some low-grade and fake paints are also important reasons for the excessive benzene content in indoor air.

What are the hazards of harmful substances in paints and coatings to human body?

1, chronic benzene poisoning, mainly benzene has * * effects on skin, eyes and upper respiratory tract.

2, long-term inhalation of benzene can lead to aplastic anemia.

3. Women are more sensitive to benzene and its homologues than men. Toluene and xylene also have some effects on reproductive function.

4. Benzene can cause fetal congenital defects.

How to prevent the harm of benzene in indoor air?

1. Try to use decoration materials that meet the national standards and have less pollution, which is the fundamental to reduce the benzene content in indoor air. For example, choose paints, adhesives and coatings produced by regular manufacturers, and choose water-based materials with no pollution or less pollution. At the same time, remind everyone to pay attention to the choice of adhesives, because there are no regulations on the use of adhesives in various laws and regulations of the building decoration industry, and ordinary people have no experience. Decoration companies can use whatever they want, which is easy to be ignored.

2, the choice of construction technology. Some decoration companies use paint instead of 107 glue to seal the wall, which increases the benzene content in the indoor air. In addition, when painting waterproof, the construction technology is not standardized, which greatly increases the benzene content in indoor air. Some residents have reported that the building of a decoration company is full of peculiar smell. This kind of high-concentration benzene in the air is very dangerous, which not only makes people poisoned, but also easily leads to explosions and fires.

3, should strengthen the labor protection of construction workers. The construction site should pay attention to ventilation as much as possible to reduce the harm of benzene in the workplace air to human body. Paint coating construction is most afraid of sandstorm weather, because dust falling on the paint film will affect the coating effect. Therefore, this kind of construction is generally carried out with the doors and windows closed. If the amount of painting is large, the indoor temperature is high, the construction time is long, and the benzene accumulated in the air is too high, it will lead to poisoning. Never stay in a closed room.

4. Keep the indoor air clean. This is an effective way to eliminate indoor harmful gases. You can choose an effective indoor air purifier and ventilation device. Or open the window for ventilation when the outdoor air is good, which is beneficial to the emission and discharge of indoor harmful gases.

Don't move into the decorated room immediately. After the decoration of the living room is completed, keep a good ventilation environment in the room and wait for benzene and organic matter to be released for a period of time before living.

6, strengthen the safety management of paint construction site. Paint and whitewash construction projects should not be done together with carpentry such as furniture, heating and wood floor installation. Different materials such as wood, paint and coating should not be mixed together or put in one room, but should be placed separately. Flammable materials such as paint should be stored in a ventilated place. Smoking and cigarette butts are not allowed on the construction site. Fire extinguishers should be prepared at the construction site.

Experts warn that when working in some toxic environments. Pay attention to maintaining a good ventilation environment; Pay attention to wearing protective equipment; Choose low-toxic items; Try not to live in a toxic environment for a long time, and don't stay too long. If you find symptoms such as dizziness, poor memory, insomnia, fatigue and poor physical activity, you should go to a specialized hospital for examination and treatment in time to avoid irreversible brain damage.

Many inferior paints and adhesives contain benzene, and these organic compounds can enter the human body through the respiratory tract and skin, infringing on the nervous system, hematopoietic system and liver organs. Leukopenia was the main cause in the early stage of poisoning, and skin purpura, gingival bleeding and nosebleed appeared in the middle stage. It may happen, and finally it may happen aplastic anemia or aplastic anemia.

Question 2: Will the antirust paint still contain formaldehyde after one year? Antirust paint itself does not contain formaldehyde. The harmful component in antirust paint is benzene. (At present, only benzene is used as a low-priced and inferior diluent), and xylene is basically used instead. This is also toxic, but it is relatively less toxic and can be metabolized by the liver. As long as it is not allergic, or long-term high-dose contact, it will not cause harm.

Question 3: Is antirust paint toxic? 10 has a great influence. Both antirust paint and wood paint contain chemicals. The bigger the smell, the scarier the paint and the more chemicals. If your sister doesn't stay away from this smell, it will have a great influence on the children born in the future. Hope to adopt.

Question 4: Is antirust paint harmful to health? For paint, in people's general thinking, it will be considered that paint is very harmful. Paint is like drugs. When it comes to poison, it turns pale. But people don't know what harm paint does. Let's talk about it below! Common toxic substances in paint:

1. Toluene and xylene

Toluene and xylene are moderately toxic solvents in solvent classification, which have anesthetic effects on human body and * * *.

It is toxic to nervous system at high concentration, but the residual toxicity in human body is low, which can generally be eliminated by metabolism. The maximum allowable concentration in the air is 100mg/m3. People who have been exposed to toluene and xylene for a long time should not drink white wine, not to mention excessive alcohol, because alcohol will prolong their stay in the body and is extremely harmful to health. The workplace should maintain air circulation to reduce its concentration in the air. The latest research data show that toluene and xylene will have a certain photochemical reaction after entering the atmosphere, which will destroy the ozone layer to some extent.

2. Benzene

Benzene is a highly toxic solvent and an aromatic volatile organic compound, which is harmful to human nervous system.

It has anesthetic and * * * effects. A small amount of inhalation can also cause long-term harm to the human body. Benzene can accumulate in the nervous system and bone marrow, causing damage to the nervous system and hematopoietic tissue and reducing the number of white blood cells and platelets in the blood. Long-term exposure can lead to leukemia.

3. Ethylene glycol ether solvent

Glycol ether solvents will form highly toxic compounds after metabolism in the body, causing permanent damage to the blood circulation system and nervous system of the human body, and long-term exposure to high concentration of glycol ether.

Solvents can cause cancer. In addition, glycol ether solvent will cause permanent damage to female reproductive system, leading to female infertility.

4. Toluene diisocyanate

TDI vapor pressure is low, which has a strong effect on human cornea and causes eye swelling. Inhalation of TDI vapor will damage human liver and kidney function, and long-term exposure to high concentration TDI vapor will cause cancer. In polyurethane (PU) coatings, the free TDI of curing agent component is less than 0.5%, which is basically harmless to health.

5. Heavy metals

Heavy metals mainly exist in paint, mainly from the pigment part of paint. Excessive intake of heavy metals can cause chronic poisoning. Heavy metals affect children's growth and development, especially their intellectual development. Some heavy metals will remain in the brain and internal organs, causing permanent damage to the liver and kidneys. Unfortunately, pigments without heavy metals are expensive.

6. phthalate plasticizers

Phthalate plasticizer is the most widely used plasticizer in volatile coatings, and it was considered harmless to human body for quite some time in the past. However, according to the latest research in Europe and America, this plasticizer has no obvious adverse effects on adult health, but it will have adverse effects on children's development, mainly causing precocious puberty in children. So recently, European and American standards

It has been clearly stipulated that this kind of plasticizer is prohibited in children's toys.

7. Volatile organic compounds

Vocs are volatile organic compounds. According to incomplete statistics, China's coating industry releases about 3 million tons of volatile organic compounds into the atmosphere every year, which directly pollutes the atmospheric environment, damages the living environment of human beings, harms human health and causes huge waste of resources, which is incompatible with the current renewable and sustainable economic model.

8. Formaldehyde

Formaldehyde is a * * * gas, which can damage the respiratory tract and internal organs. Inferior wall putty, which mainly exists in adhesives and water-based paints, is also a big source. The most harmful substances of paint to human body are formaldehyde, benzene, TVOC and so on.

Formaldehyde is a colorless and soluble gas. Wood-based panels such as particleboard, density board, plywood, adhesive and wallpaper are the main sources of formaldehyde in the air, and the release period is as long as 3 ~ 15 years. It can be absorbed through respiratory tract, and the harm of formaldehyde to human body has the characteristics of long-term, latent and concealed. Long-term inhalation of formaldehyde can cause serious diseases such as nasopharyngeal carcinoma and laryngeal cancer. Benzene is a colorless gas with a special aromatic smell. Glue, paint, coating and adhesive are the main sources of benzene in the air. Benzene and benzene series can be anesthetized by the central nervous system after being inhaled by human body; It can inhibit human hematopoietic function, reduce red blood cells, white blood cells and platelets, and increase the incidence of aplastic anemia; It can also lead to abnormal menstruation in women and fetuses.

Congenital defects, etc.

TVOC's total volatile organic compounds, VOC and the abbreviation of volatile organic compounds, as heterogeneous pollutants in indoor air, are generally not listed one by one because of their low concentration but various types. & gt

Question 5: Is antirust paint toxic? Is the antirust paint poisonous? Antirust paint itself contains formaldehyde, which is harmful to benzene (benzene is currently used as a low-priced and inferior diluent). Basically, xylene is used instead of toxicity, which is more sensitive to physical fitness than liver metabolism or damage caused by dose exposure.

Question 6: Is alkyd antirust paint toxic? There is toxicity, and the difference is only in toxicity.

Question 7: Is red lead antirust paint a toxic substance? As far as red lead pigment is concerned, there are two kinds, one is imitation red lead color, which is non-toxic. One is true red lead, which is poisonous. As far as the effect is concerned, true red lead is better.

Question 8: Is antirust paint applied to water tanks harmful to human body? The inner wall of the drinking water tank cannot be coated with antirust paint, and toxic substances will dissolve into the water. Commonly used for antirust of edible water tanks.

Food grade resin, stainless steel material, plastic, etc.

Other inedible water tanks can be used.

Question 9: What kind of antirust paint is nontoxic? The toxic components of paint itself are mainly solvents and fillers.

Paint barbells without antirust paint. Antirust paint for industrial paint is not suitable for your barbell. Any paint itself has anti-rust function, and barbells should be painted beautifully. I recommend alkyd paint for several reasons: 1, which is convenient to brush. Brush with soft wool, no scratches, you can brush directly without thinning. 2. Various colors and high gloss. Alcoholic acid paint is used as topcoat and is the most commonly used decorative topcoat. 3, the toxicity is small. Diluent is not toxic, although the taste is a bit strong, but the taste has nothing to do with toxicity. As long as it is dried outdoors for about 2 days, the dried paint film is nontoxic and tasteless. 4. Alkyd paint is the cheapest paint.

Remember! The surface treatment of barbell should be done well before painting, otherwise embroidery painting will reduce the life of paint film and the paint film will fall off after a long time.

Surface treatment method: In view of its own operation, simple surface treatment method can be adopted. Use sandpaper to grind the rusty parts repeatedly until the rust spots disappear completely. If the rusty part is also painted, use sandpaper to polish the metal surface repeatedly (horizontally+vertically+circularly) until it is rough. Rinse/brush the polished surface with solvent (gasoline is OK, alcohol is not OK, water is not OK) after polishing, and then paint it after drying.

If you have difficulty, you can just draw it. It won't fall off for a year.
