High-intensity durable heat insulation building material as well as preparation method and application thereof

Abstract

The invention discloses a high-intensity durable heat insulation building material as well as a preparation method and application thereof. An inorganic heat insulation building material is prepared from the following ingredients including magnesium oxide, magnesium sulfate, magnesium chloride, talcum powder and ultrafine building material efficient additives. After being smeared onto the surfaceof a polystyrene heat insulation plate, the heat insulation building material tightly covers the polystyrene heat insulation plate, and can comprehensively seep into the inside of the polystyrene heatinsulation plate; the mutual seepage is realized under the high-pressure effect; after the forming, a compact water-tight and air-tight hard framework is formed; the polystyrene heat insulation platecovered at the inside is protected; the water absorption rate of the polystyrene heat insulation plate is reduced; the transmission rate of air and water vapor is effectively prevented; the anti-aging performance of the polystyrene heat insulation plate is improved.

Description

technical field

[0001] The present invention relates to a building material, in particular to a high-strength and durable thermal insulation building material for building exterior walls. The present invention further relates to a preparation method of the thermal insulation building material and its application in construction, which belongs to flame retardant, Anti-aging building materials field.
