The fireproof board is a refractory building material for surface
decoration. The fireproof board is the original paper (titanium
paper, kraft paper) through the impregnation process of melamine
and phenolic resin, which is made through high temperature and high
1. mineral wool board and glass wool board: mainly mineral wool and
glass wool as insulation materials. Its own non flammable, high
temperature resistance, light quality, but the shortcomings are:
(1) short fiber will cause harm to the human respiratory system;
(2) the plate strength is poor; (3) the plate is poor in the spread
of fire smoke; (4) the decoration is poor, and the workload of
installation and construction is large. Therefore, most of the
plates have evolved into inorganic binder materials, mineral wool
and glass wool as reinforcing materials.
2. cement board: cement plate has high strength and wide range of
sources. In the past, it was used as a fire-resistant ceiling and
partition wall, but its fire resistance was poor, and it was easily
cracked and perforated in the fire field, and its application was
limited. The thermal insulation and sound insulation properties of
cement concrete components are good, and can be used as partition
walls and roof panels.
In the building materials market, there have been some improved
varieties of fiber reinforced concrete, which have the advantages
of high strength and good fire resistance, but poor toughness,
large alkalinity and poor decorative effect.
3. perlite plate, floating bead board and leech plate are hollow
plates made of low alkalinity cement as base material, perlite,
glass bead and vermiculite as filling material, and then adding
some additives. It has the characteristics of light weight, high
strength, good toughness, fireproof and heat insulation and
convenient construction. It can be widely used in the non
load-bearing parts of high-rise frame building, household, toilet,
kitchen, communication tube and so on.
4. fireproof gypsum plank: since gypsum's fire resistance is widely
accepted, gypsum based fireproof board has developed rapidly. The
main component of the board is non flammable and contains crystal
water, and its fire resistance is good. It can be used as partition
wall, ceiling and roof panel. The sheet material is rich in raw
materials and convenient for factory stereotype production.
In use, it is lighter in weight, can reduce the weight bearing of
the building, and easy to process. It can be sawed and planed,
convenient for construction and good decoration, but its flexural
performance is poor. There are many factors affecting the
fire-resistant properties of plasterboard, such as composition,
type of plate, type of keel, thickness of plate, no packing in air
layer, and the way of assembling and so on.
In recent years, silicon calcium gypsum fiber has been found.
New varieties such as dimension board, double-sided sticker, gypsum
fireproofing board and so on.
5. calcium silicate fiber board is a building plate with lime,
silicate and inorganic fiber reinforced material as the main raw
material. It has the characteristics of light quality, high
strength, heat insulation, good durability, good processing
performance and good construction performance. It is mainly used
for making ceiling, partition wall and fireproof material as steel
column and steel beam. But the strength and bending properties of
the plate still need to be improved.
6. magnesium oxychloride fire retardant board: magnesium
oxychloride cement products, magnesia cementitious material as the
main body, glass fiber cloth reinforced material, light insulation
material as filler composite, can meet the non flammability
requirements, is a new type of environment-friendly sheet.
