Problems solved by technology

However, the thermal insulation performance of the interface agent itself is poor, which affects the overall thermal conductivity of the benzene board. In the early stage of a fire, it is difficult to resist the sudden rise in temperature, resulting in the instantaneous transfer of heat to the polystyrene insulation board, causing the board to shrink when heated, causing the outer layer of the interface agent to fall off. , lose the initial fire protection ability

Abstract

The invention relates to a heat-insulating fireproof interface agent for a polystyrene heat-insulating plate. The heat-insulating fireproof interface agent comprises 20-25 parts of silicate cement, 2-5 parts of coal ash, 2-3 parts of bauxite cement, 0.4-0.6 parts of plasticizer, 0.5-1.0 part of water reducer, 0.1-0.2 parts of ethylene oxide, 0.1-0.2 parts of tartaric acids, 0.1-0.2 parts of calcium stearate, 0.05-0.1 parts of polypropylene cellulose, 5-8 parts of vinyl acetate / ethylene polymer, 4-6 parts of 200 mesh sand, 4-6 parts of 400 mesh sand, 5-8 parts of 800 mesh coarse whiting, 5-8 parts of kaolin, 8-10 parts of aluminum oxide, 5-10 parts of magnesium hydroxide, 3-5 parts of zinc borate, 8-13.5 parts of ammonium polyphosphate, 0.2-0.5 parts of 1-2mm basalt fibers and 8.5-15 parts of expanded perlite. The heat-insulating fireproof interface agent for the polystyrene heat-insulating plate has the advantages of simple construction, excellent fireproof heat-insulating effect, excellent cracking resistance and high bonding strength with the polystyrene heat-insulating plate.

Description

technical field [0001] The invention relates to a heat-insulation and fire-proof material, in particular to a heat-insulation and fire-proof interface agent coated on the surface of a polystyrene insulation board. Background technique [0002] Polystyrene insulation board is cheap and has good thermal insulation performance, and is widely used in building insulation systems. However, in recent years, fire accidents of insulation materials and external wall insulation systems have occurred frequently. Frequent building insulation fire accidents have not only caused huge economic losses and environmental pollution, but also seriously threatened the safety of people's lives and properties. There is no doubt that it is very important to emphasize the fire safety of the external wall insulation system. In the thermal insulation system widely used at present, polystyrene is the key to its fire safety performance. From the current technical level, it is difficult to achieve high-...
