Problems solved by technology

The traditional EPS board has good thermal insulation performance and is the first choice for energy-saving buildings, but its disadvantage is that it is flammable. Because of its high fire hazard, its use is strictly controlled according to the building elevation in architectural design, which greatly reduces its scope of use.

Abstract

The invention relates to a self-sintered fireproof polyphenyl thermal insulation material, which comprises the following components by weight: 2-4 parts of polystyrene EPS foamed particles; 0.5-1.5 parts of waste benzene grains; and 15-33 parts of a magnesium oxychloride cement paste gelling agent, which is composed of magnesium oxychloride cement and a coagulant in a weight ratio of 1:0.02-0.05. The magnesium oxychloride cement comprises MgO, MgCl2 and H2O in a weight ratio of 3:1:11. The coagulant consists of MgSO4 and sulfone crown ether that are added in a weight ratio of 1:0.05. The preparation method provided by the invention consists of the steps of: die preparation, preparation of the magnesium oxychloride cement paste gelling agent, mixing stirring, die-filling and pressurization, bolt rod locking, curing, die removing and cutting, quality inspection and packaging, etc. Compared with the prior art, the manufacturing process involved in the invention is simple, simplifies the traditional process, reduces boiler gas consumption, and is energy-saving and cost-reducing; reuse of waste benzene grains is realized, and the environmental pollution is reduced; and the finished product has good thermal insulation performance and fireproof performance, high strength, low density, long service life, and vast market prospects.

Description

technical field [0001] The invention relates to a building wall thermal insulation material, in particular to a self-sintering fireproof polystyrene thermal insulation material and a preparation method thereof. Background technique [0002] Conventionally manufactured expanded polystyrene materials are expanded polystyrene EPS raw material particles under the action of hot pressure of steam, foamed into particles larger than the raw material particle size, called pre-expanded polystyrene particles, and then pre-expanded polystyrene Styrene particles are put into a sealed mold of a certain size, steam is passed through for secondary foaming, expansion and sintering are formed, and after aging, they are cut into required materials. The traditional EPS board has good thermal insulation performance and is the first choice for energy-saving buildings. However, its disadvantage is that it is flammable. Because of its high fire hazard, its use is strictly controlled according to th...
