insulation board for building

Abstract

The invention belongs to the technical field of thermal insulation boards and particularly relates to a thermal insulation board for a building. The thermal insulation board comprises thermal insulation layers, a fireproof layer and a sound insulation layer. The thermal insulation layers comprise a first thermal insulation layer and a second thermal insulation layer. Both the first thermal insulation layer and the second thermal insulation layer are internally provided with thermal insulation cores which are formed by polyurethane rigid foam. Two sides of the two thermal insulation cores are provided with protective plates, and dry soils are in the protective plates. A gap is between the first thermal insulation layer and the second thermal insulation layer and is internally provided witha spring connected between the first thermal insulation layer and the second thermal insulation layer. Upper and lower ends in the gap are provided with square airbags which are fixedly connected between the first thermal insulation layer and the second thermal insulation layer. The square airbags are filled with sand. The fireproof layer is made by mixing sea mud and glass powder. The thermal insulation board has the advantages of simple structure, cheap material, the effects of thermal insulation, sound insulation and fire protection and high impact resistance ability.

Description

technical field [0001] The invention belongs to the technical field of thermal insulation boards, in particular to a thermal insulation board for buildings. Background technique [0002] The insulation board is easy to understand, it is a board for building insulation. It has moisture-proof and waterproof properties, which can reduce the thickness of the building's outer protective structure, thereby increasing the indoor usable area. [0003] There are also some technical solutions for the production of thermal insulation boards in the prior art, such as a Chinese patent with application number 2014101215250, a detachable polyurethane cold storage thermal insulation board, including sandwich panels, fireproof layers, bonded mortar layers, Taste moisture-proof device; The fireproof layer includes an upper fireproof layer and a lower fireproof layer, the upper fireproof layer is connected with the upper surface of the sandwich panel through the bonding mortar layer, and the ...

AI Technical Summary

Problems solved by technology

[0005] In order to make up for the deficiencies of the existing technology and solve the problems of easy falling off, poor heat preservation effect and inability to ensure continuous work under the condition of impact force, the invention proposes a kind of building insulation board, which is better fixed and sound-proof by trapezoidal buckles Layer, through the gap between the No. 1 insulation layer and the No. 2 insulation layer, the impact is effectively weakened, and the impact is prevented from falling off and destroying the insulation board; through the combination of the insulation layer and the fireproof layer, the indoor insulation and fire prevention are carried out. , so that the thermal insulation effect and fire prevention effect are more significant
