Abstract

The invention discloses a high-strength durable thermal insulation building material and a preparation method and an application thereof. The inorganic thermal insulation building material comprises the following components: magnesium oxide, magnesium sulfate, magnesium chloride, talcum powder and an ultra-micro building material high-efficiency additive. When the thermal insulation building material is smeared on the surface of a polystyrene thermal insulation board, the thermal insulation building material not only firmly wraps the polystyrene thermal insulation board, but also penetrates into the interior of the polystyrene thermal insulation board, penetrates with each other under high pressure, forms a compact water-impermeable and gas-impermeable rigid framework after forming, protects the polystyrene thermal insulation board included in the thermal insulation building material, reduces the water absorption rate of the polystyrene thermal insulation board, and effectively prevents the penetration rate of air and water vapor, and improves the aging resistance of the polyphenyl thermal insulation board.

Description

technical field [0001] The present invention relates to a building material, in particular to a high-strength and durable heat-insulating building material used for building exterior walls. The present invention further relates to a preparation method of the heat-insulating building material and its application in construction, which belongs to flame-retardant, fire-proof Field of aging building materials. Background technique [0002] Polystyrene insulation board is one of the most commonly used insulation materials in building external insulation. It is a high-quality heat insulation and insulation material commonly used in the construction industry. It is widely used in wall insulation, flat concrete roof and steel structure roof insulation. Moisture-proof and thermal insulation for low-temperature storage ground, airport runways, highways, etc. [0003] Polystyrene insulation board is the lightest insulation material with the same volume and weight among similar product...
