What material is the fireproof board made of?

Fireproof board is made of base paper (titanium powder paper, kraft paper) through the impregnation process of melamine and phenolic resin under high temperature and high pressure.

Classification of fire boards:

1

, mineral wool board, glass wool board

Mineral wool and glass wool are mainly used as heat insulation materials. It is nonflammable, high temperature resistant and light in weight, but its disadvantages are as follows:

① Short fiber will do harm to human respiratory system;

(2) The plate strength is poor;

(3) The board has poor barrier performance to the spread of fire smoke;

(4) Poor decoration.

⑤ The workload of installation and construction is heavy. Therefore, most of these boards have evolved into boards with inorganic bonding materials as the base material and mineral wool and glass wool as the reinforcing materials.

2, cement board

Cement board has high strength and wide sources. In the past, it was often used as a fire-proof ceiling and partition wall, but its fire resistance was poor, and it was easy to burst and puncture in case of fire, losing its protective effect, which limited its application.

Cement concrete members have good thermal and sound insulation properties and can be used as partition walls and roof panels. Improved varieties such as fiber-reinforced cement board have appeared in the building materials market, which have the advantages of high strength and good fire resistance, but poor toughness, high alkalinity and poor decorative effect.

3, perlite board, floating bead board, vermiculite board

It is a hollow slab made of low alkalinity cement, perlite, glass beads and vermiculite as aerated filling materials and some additives.

It has the characteristics of light weight, high strength, good toughness, fire prevention and heat insulation, and convenient construction. , can be widely used in rooms, homes, bathrooms, kitchens, communication pipes and other non-load-bearing parts. High-rise frame building.

4. Fireproof gypsum board

Since the fire resistance of gypsum has been widely accepted, gypsum-based fire boards have developed rapidly. The main component of the board is incombustible and contains crystal water, so it has good fire resistance.

It can be used as partition wall, ceiling and roof slab. The raw material source of the plate is rich, which is convenient for the factory to finalize the design and production. When used, it is light in weight, which can reduce the bearing capacity of the building, and it is easy to process and saw flat, convenient to construct and good in decoration, but poor in bending performance.

There are many factors that affect the fire resistance of gypsum board, such as composition, plate type, keel type, plate thickness, air layer with or without filler, assembly method and so on. In recent years, new varieties such as calcium silicate gypsum fiber fireproof board, specification board and double-sided adhesive gypsum fireproof board have appeared.

Extended data

Characteristics of fireproof board materials:

1, convenient for processing

It can be sawed, drilled, ground and nailed, and it is easier to reflect the design intent;

2, heat preservation

Its thermal insulation performance is 6 times that of glass, 3 times that of clay and 10 times that of ordinary concrete.

3. Light weight and high strength

It is 1/4 of ordinary concrete and 1/3 of clay brick, which is lighter than water and equivalent to wood. Cubic compressive strength ≥4mpa.

Especially in steel structure engineering, using ALC slab as enclosure structure can give full play to its advantages of light weight, high strength, good ductility and strong earthquake resistance.

4. Flame retardant

Aerated concrete is inorganic, will not burn, and will not produce harmful gas at high temperature; At the same time, the thermal conductivity of aerated concrete is very small, which makes the heat transfer slow and can effectively resist fire and protect its structure from fire.
