Description

technical field [0001] The invention relates to a prefabricated board, in particular to a high-strength fireproof prefabricated board and its production process. Background technique [0002] There are many kinds of prefabricated boards. The traditional ones are basically rigid foam made of polystyrene resin as raw material plus other raw and auxiliary materials and polymers. They are heated and mixed while injecting catalysts, and then extruded. Board, which has the characteristics of light weight, moisture-proof, waterproof, etc., but this kind of insulation board does not have the function of fire prevention. Due to its materials, varieties, and specifications, the use value of fireproof prefabricated panels is becoming more and more abundant. Its characteristics of heat preservation, heat insulation, light weight, high strength, fire resistance, and flame retardancy have been widely used in interior decoration, furniture, and kitchen cabinets in society. , Laboratory co...
