Problems solved by technology

[0002] The existing known cement boards or concrete boards are heavy in weight, poor in heat insulation and sound insulation, and poor in waterproof effect; for this reason, the prior art has further designed a composite board with a three-layer structure. The soil material is filled with a polyurethane foam core layer, which has a certain heat and sound insulation effect, but there is still room for improvement

Embodiment

[0034] A waterproof layer is laid on the upper and lower surfaces of the polyurethane foaming mould. The thickness of the waterproof layer is controlled at 0.06mm. The two opposite surfaces of the waterproof layer are respectively coated with polyurethane adhesive. The waterproof layer has a diameter of 25 microns and a length of The 6 mm impermeable polypropylene staple fiber is flocked on the two surfaces of the impermeable polypropylene core film at a ratio of 3.5 million fibers per square meter. The flocking is flocked by an electrostatic machine. The core film is made of polypropylene material and is made of non-woven fabric by spunbonding; the middle distance between the upper and lower molds is controlled to 30mm, and the foaming material is injected into the middle cavity of the mold. The ratio of the main components of polyether polyethanol and isocyanate is 1:1, the foaming temperature is 35℃, the foaming and stabilization time is 30 minutes, and the final polyurethane...

Abstract

The invention relates to a multilayer composite board for construction, which is sequentially provided with a concrete layer for fiber reinforcement, a stress dispersion layer, a waterproof layer, a polyurethane foam temperature preservation layer, a waterproof layer, a stress dispersion layer, a concrete layer with fiber reinforcement, a heat insulation layer and a reflection layer from inside to outside, and each layer has specific materials and thickness. The multilayer composite board for construction provided by the invention has excellent performances, favorable heat insulation and sound insulation effects, light weight and good waterproof effect.

Description

Technical field [0001] The invention relates to a building board, in particular to a multi-layer composite board for building. Background technique [0002] The existing known cement board or concrete board is relatively heavy, has poor heat and sound insulation effect, and has poor waterproof effect; for this reason, the prior art further designs a three-layer structure composite board, which is mixed on two layers. The soil material is filled with a polyurethane foam core layer, which has a certain heat and sound insulation effect, but still has room for improvement. Summary of the invention [0003] Therefore, the technical problem to be solved by the present invention is to overcome the problems in the prior art and provide a multi-layer composite board for construction with excellent comprehensive performance, which not only has good heat insulation and sound insulation effects, but also has light weight and good waterproof effect. . [0004] To solve the above technical prob...
