Abstract

The invention discloses a heat-insulation and sound-insulation composite plate which comprises a first fixing layer, a first adhesion layer, a sound-insulation layer, a straw plastic layer, a third adhesion layer and a second fixing layer. The first fixing layer and the second fixing layer comprise PVC (polyvinyl chloride) transparent abrasion-resistant sheets, PVC pattern films and PVC calendered sheets; the adhesion layers are made of environment-friendly adhesive or hot-melt adhesive; the sound-insulation layer is made of low-density polyethylene resin, cross-linking agents and foaming agents by means of high-temperature continuous foaming; crop straw, high-density polyethylene, phenolic resin adhesive and coupling agents are mixed with one another according to a weight ratio of 50-55%:35-40%:5%:5%, are stirred, are subjected to hot-press and are laid to form the straw plastic layer.

Description

technical field [0001] The invention relates to the technical field of thermal insulation and sound insulation composite materials, in particular to a method for preparing a thermal insulation and sound insulation composite 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] ...
