Abstract

A fireproof insulation sheet material and a processing technology thereof relate to a building decoration material. The fireproof insulation sheet material includes, by weight percentage, 8%-27% of foam insulation particles, 10%-30% of a resin adhesive agent, 2%-8% of an acid agent, 10%-20% of a quartz material, 10%-20% of expanded graphite, 10%-30% of a heat absorbing material, and 6%-18% of an insulation stone flour or insulation asbestos. The processing technology of the fireproof insulation sheet material is simple and practicable, the foam particles are provided with micropores, so as to facilitate infiltration of other raw materials into the foam particles. The prepared fireproof insulation sheet material has the advantages of safety, environment-friendliness, no pollution, excellent insulating performance, long service life, no smoke emission in high temperature, resistance to high temperature of 1000 DEG C, fire performance reaching A-level, and thermal conductivity less than 0.039 w / m.k.

Description

technical field [0001] The invention relates to a building decoration material, in particular to a fireproof and thermal insulation board and its processing technology. Background technique [0002] Since the reform and opening up, my country's construction industry has developed continuously and rapidly. The status of the construction industry as a pillar industry in the national economy has been continuously strengthened, and its role in stimulating the national economy has become more significant. Building materials are the material basis of construction engineering. Fireproof and thermal insulation materials are new building materials that are commonly used, and are widely used in the insulation construction of walls and floors. Due to the occurrence of many building insulation fire incidents in recent years, it has triggered the thinking of all walks of life on thermal insulation and fire prevention. The fire performance of thermal insulation materials has attracted unp...
