Problems solved by technology

Its main disadvantages are: first, because it contains a large amount of chemical adhesive components, it will release harmful gases such as formaldehyde for a long time, which will damage the health of the occupants; second, due to the high density, the lightweight characteristics of straw boards cannot be fully displayed.
Third, air pollution is harmful to the health of construction workers

Abstract

The invention discloses a multi-layer structure composite board manufactured by squeezing glue-free straw boards at a high temperature. The two large faces of a composite core board are each provided with a layer of composite outer layer wood board in a composite mode. The composite core board comprises a center skeleton board on the center layer. The two large faces of the center skeleton board are each provided with one layer of glue-free straw board in a composite mode. The outer large face of each glue-free straw board is provided with a fireproof board in a composite mode. A five-layer board formed by the glue-free straw boards, the fireproof boards and the center skeleton board has two opposite flush side faces. The two flush side faces are each provided with a layer of peripheral skeleton board in a composite mode. The two opposite side faces of the two composite outer layer wood boards are flush with the outer edges of the side faces of the peripheral skeleton boards on the same sides as the two composite outer layer wood boards. The composite board has the advantages of being free of glue and air pollution, low in density and light, has the enough connecting performance and strength, is good in flexibility and enables a wall to achieve self bearing, no joist is needed, deformation is avoided, the multi-layer structure composite board has the advantages of water resistance, impact resistance, radiation resistance and the like, and the service life of the board is as long as that of a building.

Description

technical field [0001] The invention relates to a multi-layer structure composite board as a building board module. In particular, it relates to a multi-layer structure composite board prepared by extruding a non-adhesive straw board at high temperature. Background technique [0002] Straw board is an ecological and renewable resource, and has a good thermal insulation effect. A large number of straw resources are used in the construction field to avoid the pollution of the atmosphere caused by straw burning. In addition, the straw board has the characteristics of lightness and low cost. It can be used as a building wall board or floor board to reduce the weight of building materials as a whole, and greatly reduce the transportation cost of building materials and construction costs. [0003] Straw boards have been applied in the market as the main material for wall insulation, and belong to the prior art. However, in order to improve the formability and connectability of ...
