Inorganic light insulating mortar composite XPS (Extruded Polystyrene) insulating board and preparation method thereof

Abstract

The invention discloses an inorganic light insulating mortar composite XPS (Extruded Polystyrene) insulating board and a preparation method thereof. The composite XPS insulating board comprises an XPS substrate, an interface agent layer and an inorganic light insulating mortar layer, wherein the front surface and the back surface of the XPS substrate are provided with grooves; the inorganic light insulating mortar layer is made of composite gridding cloth; the interface agent layer is arranged on the XPS substrate with the grooves on the front surface and the back surface; and the inorganic light insulating mortar layer made of composite gridding cloth is arranged on the interface agent layer. Compared with the prior art, the prepared A-grade fireproof insulating board is uniform in thermoengineering property, not only has high-efficiency insulating effect, but also has good fire resistance and can be widely used in building wall bodies as the insulating board.

Description

technical field [0001] The invention relates to building thermal insulation materials, in particular to an inorganic lightweight thermal insulation mortar composite XPS thermal insulation board and a preparation method thereof. Background technique [0002] In recent years, the fires of building external insulation materials have caused serious casualties and property losses. Building flammable and combustible external organic insulation materials have become a new type of fire hazard. Relevant national departments have issued documents to limit the use of flammable and combustible insulation materials. Although inorganic thermal insulation materials have many advantages such as high strength and fire prevention, their thermal insulation effect is far inferior to that of organic materials, and their construction techniques and methods are not as mature and convenient as organic materials.

Problems solved by technology

[0002] In recent years, fires in building external insulation materials have caused serious casualties and property losses. Building flammable and combustible external organic thermal insulation materials have become a new type of fire hazard. Relevant national departments have issued documents to limit the use of flammable and combustible thermal insulation materials.

Although inorganic thermal insulation materials have many advantages such as high strength and fire prevention, their thermal insulation effect is far inferior to that of organic materials, and their construction techniques and methods are not as mature and convenient as organic materials.

[0003] Most of the A-grade materials on the market now have disadvantages such as poor thermal insulation performance, unstable products, and short supply.
