Abstract

The invention belongs to the technical field of board preparation, and particularly relates to a preparation method of a shock-resisting, heat-preservation and sound-proofing board. The preparation method comprises the steps: firstly, waste circuit boards are collected, crushed and then screened, and thus waste circuit board powder is obtained; then montmorillonite is crushed, then fused and wire-drawn, and self-made mineral fibers are obtained; and then a polyurethane component A and a modification component B are prepared, mixed and pre-polymerized, then the pre-polymerized material is injected into a mold, foaming is carried out in a drying box, and then curing is carried out at room temperature, and finally the shock-resisting, heat-preservation and sound-proofing board is prepared. The prepared shock-resisting, heat-preservation and sound-proofing board is high in compressive strength, breaking strength and tensile strength, low in thermal conductivity coefficient, good in heat preservation performance and high in sound-proofing coefficient, and has wide application prospects.

Description

technical field [0001] The invention belongs to the technical field of board preparation, and in particular relates to a preparation method of an impact-resistant heat-preservation and sound-insulating board. Background technique [0002] With the decrease of forest resources in the world and the shortage of wood raw materials, people turn their attention to non-wood biomass resources such as wheat straw, corn stalk, cotton stalk, sorghum stalk, etc. For countries with scarce forest resources, how to reduce the burning loss of biomass resources and realize the comprehensive utilization of biomass resources is an urgent task at present. [0003] Using biomass as the main raw material, people have developed a series of composite products that meet human life and production, the most important of which include various biomass straw-based panels, biomass straw-thermosetting polymer composites and biomass straw-thermal Plastic plastic composites. [0004] As a building decorati...
