Thermal insulation type co-extrusion wood-plastic-carbon fiber composite board

Abstract

The invention discloses a thermal insulation type co-extrusion wood-plastic-carbon fiber composite board. The composite board comprises a surface layer and an inner layer. The surface layer covers theinner layer. An infrared reflection toner, nanoscale metal tungsten powder and titanium dioxide powder are added to a surface layer material, and therefore the temperature of the surface material islowered; carbon fiber is used for replacing glass fiber in the inner layer material, and therefore the heat absorption performance of the inner layer material is improved on the premise of ensuring high strength, and the heat energy of the surface layer material is absorbed to the inner layer material. In the processing process of the surface layer and the inner layer, no glue or other adhesives need to be added, clear resin, modified resin and maleic anhydride grafting resin with adhesiveness are used in the surface layer raw material, HDPE resin and a coupling agent with adhesiveness are used in the inner layer raw material, the inner layer material and the surface layer material are attached to wood powder through extrusion, and the surface layer and the inner layer are sufficiently attached.

Description

technical field [0001] The invention relates to a composite floor, in particular to a thermal insulation co-extruded wood-plastic carbon fiber laminated board. Background technique [0002] Wood-plastic composite materials are polymer materials such as wood and plastic, which are processed and formed by special processes. Wood-plastic composite materials have the characteristics of various raw materials, superior product performance, and recyclability. They are widely used in Construction, packaging, garden yard, etc. As an emerging environment-friendly industry, wood-plastic composite boards have strong functional design. Selecting appropriate fillers can not only endow high-energy or special functions, but also meet the industrial requirements of production and processing. Scholars at home and abroad have carried out extensive research on this, adding nano-materials, carbon fibers, chrysotile fibers, glass fibers, graphite, etc. can promote the comprehensive performance o...

Problems solved by technology

Scholars at home and abroad have carried out extensive research on this, adding nano-materials, carbon fibers, chrysotile fibers, glass fibers, graphite, etc. can promote the comprehensive performance of wood-plastic composites, but because the added materials are the same as wood fibers, they are different from The poor compatibility and poor dispersion of the matrix resin directly affect the modification effect of the filler on the wood-plastic composite material matrix, and the price of the added material affects the cost of the composite material, which is unfavorable for promotion

[0003] In recent years, according to the continuous feedback from the market, there is a high demand for the insulation and cooling functions of outdoor wood-plastic flooring. In high-end resorts, a large number of wood-plastic composite floorings are laid beside the swimming pools. The temperature is very high. After swimming, people get out of the water and walk barefoot to the floor, which is prone to burns.
