Description

technical field [0001] The invention belongs to the field of high-performance fibers and composite materials, and in particular relates to a preparation method of a temperature-resistant reinforced wood-plastic composite material. Background technique [0002] Wood-plastic composites (WPC) can use waste wood fiber materials and waste plastics as the main raw materials. It is environmentally friendly and recyclable. It is an important way to solve the problem of efficient utilization of natural and synthetic polymer waste resources, so it has attracted much attention. . This kind of composite material has higher surface hardness than wood, better dimensional stability, water resistance, and corrosion resistance than wood, and generally does not require surface finishing, which meets the needs of future economic development and has broad application prospects. [0003] Wood-plastic composite materials have many advantages of both wood and plastic, and their market is growing ...
