Abstract
The invention discloses a high-strength and durable heat-insulating building material, a preparation method and an application thereof. The inorganic thermal insulation building material includes the following components: magnesium oxide, magnesium sulfate, magnesium chloride, talcum powder and high-efficiency superfine building material additives. After the thermal insulation building material of the present invention is applied to the surface of the polystyrene thermal insulation board, it not only wraps the polystyrene thermal insulation board firmly, but also fully penetrates into the interior of the polystyrene thermal insulation board, and penetrates each other under the action of high pressure, forming a dense non-woven fabric after molding. The water-permeable and air-tight hard skeleton protects the included polystyrene insulation board, reduces the water absorption rate of the polystyrene insulation board, effectively prevents the transmission rate of air and water vapor, and improves the anti-aging performance of the polystyrene insulation board.
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. Background technique [0002] Polystyrene thermal insulation board is one of the most commonly used thermal insulation materials in the external thermal insulation of buildings. It is a high-quality thermal insulation and thermal insulation material commonly used in the construction industry. Low temperature storage ground, airport runway, highway and other moisture-proof insulation. [0003] Polystyrene insulation board is the lightest insulation material of the same volume and mass among similar products in the world. It is shown under the same area and thickness test that its ...
