Fireproof board is a fire-resistant building material for surface decoration, which is widely used in interior decoration, furniture, kitchen cabinets, laboratory countertops, exterior walls and other fields. The fireproof board is a base paper (titanium powder paper, kraft paper) which is impregnated with melamine and phenolic resin, and is formed at a high temperature and a high pressure. 1. Mineral wool board, glass wool board: mainly mineral wool, glass wool as insulation material. It is non-combustible, has high temperature resistance and light weight, but the shortcomings are that 1 short fiber will cause harm to human respiratory system, 2 plate strength is poor, 3 plate has poor barrier performance against fire smoke spread, 4 poor decoration, 5 The installation work is heavy. Therefore, most of this kind of plate has evolved into a plate with inorganic binder as the substrate, mineral wool and glass wool as reinforcing materials. 2. Cement board: The strength of cement board is high and the source is wide. It used to be used as a fireproof ceiling and partition wall in the past, but its fire resistance is poor. It is easy to burst and perforate in the fire field, and its protection is lost, which limits its application. The concrete and concrete members have good heat insulation and sound insulation properties, and can be used as partition walls and roof panels. In the building materials market, improved varieties such as fiber reinforced cement boards have emerged, which have the advantages of high strength and good fire resistance, but poor toughness, large alkalinity and poor decorative effect. 3. Perlite board, floating bead board, slate board: hollow board made of low alkalinity cement as base material, perlite, glass microbead and vermiculite as aerated filling material, and then added with some additives. . It has the characteristics of light weight, high strength, good toughness, fireproof and heat insulation, convenient construction, etc. It can be widely used in non-load-bearing parts such as high-rise frame building compartments, households, bathrooms, kitchens, communication pipes, etc. 4. Fireproof gypsum board: Since the fireproof performance of gypsum has been widely accepted, the fireproof board based on gypsum has developed rapidly. The main component of the plate is non-combustible and contains crystal water, and has good fire resistance, and can be used as a partition wall, a ceiling and a roof panel. The sheet material is rich in raw materials and is convenient for factory final production. In use, it has light weight, can reduce building load, and is easy to process, can be sawed and planed, convenient in construction and good in decoration, but its bending resistance is poor. There are many factors affecting the fire resistance of gypsum board, such as composition, type of board, type of keel, thickness of board, presence or absence of filler in air layer, and assembly method. In recent years, new varieties such as silicon-calcium gypsum fiberboard and double-sided sticker plaster fireproof panels have appeared. 5. Calcium silicate fiberboard: It is a building board with lime, silicate and inorganic fiber reinforced materials as the main raw materials. It has the characteristics of light weight, high strength, good heat insulation, good durability, excellent processing performance and construction performance. Mainly used for making ceilings, partition walls and fire protection materials for steel columns and steel beams. However, the strength and bending properties of the sheet have yet to be improved. 6. Magnesium oxychloride fireproof board: It belongs to magnesium oxychloride cement products. It is made of magnesium cementitious material, glass fiber cloth as reinforcing material and lightweight thermal insulation material as filler. It can meet the requirements of non-combustibility. A new type of environmentally friendly sheet.
