Description

technical field [0001] The invention relates to a wood-plastic composite material, a preparation method thereof and a molding board made of the composite material, belonging to the field of materials. Background technique [0002] Wood-plastic composites (Wood-Plastic Composites, WPC) is a new type of composite material that has been booming at home and abroad in recent years. The combination of wood and plastic has become the trend of the development of the whole society. The United States started wood-plastic composite extrusion decades ago, and it has developed very rapidly in the past five years. Since the 1990s, many countries in North America and Europe have conducted a lot of research on wood-plastic composite materials, and their production and application are also increasing rapidly. The consumption of wood-plastic composite materials in North America and Europe in 2002 reached 680,000 tons, and it is expected to grow at a rate of 14% and 19% by 2010. It not only...
