Problems solved by technology

[0002] At present, the air-filled insulation commonly used in the construction market, due to the large internal pores, high water absorption, moisture expansion, drying shrinkage, and loose surface, the surface of the insulation board is prone to cracking, hollowing, even falling off, and water seepage in the wall.
In addition, the insulation board has low strength, high thermal conductivity, and poor heat insulation, sound insulation, and gas entrainment performance. This brings problems such as high cost of insulation, complicated construction, poor durability of the insulation layer, large amount of maintenance, inconvenience of secondary decoration, etc.
At present, although there are some improved technologies, their thermal insulation performance is not ideal, and the problems of cracking, loosening and falling off have not been fundamentally solved.

Abstract

The invention discloses a fiber-reinforced aerated insulation board. The fiber-reinforced aerated insulation board is prepared from the following raw materials in parts by weight: 80-100 parts of fly ash, 30-50 parts of expanded perlite, 10-20 parts of ceramsite, 10-20 parts of plant fiber, 5-10 parts of floating bead, 5-8 parts of meerschaum, 3-5 parts of sodium fluosilicate, 3-5 parts of calcium formate, 2-4 parts of foamer, 0.1-0.5 part of oleic triisopropanolamine and 0.1-0.3 part of glycol dimethyl ether. According to the fiber-reinforced aerated insulation board, industrial production wastes are adopted as main raw materials, so that the production cost is reduced; through the organic combination and generated synergism of the fly ash, lightweight aggregate and additives, the defects in the existing building insulation boards can be effectively overcome.
