木塑，即木塑复合材料是国内外近年蓬勃兴起的一类新型复合材料，指利用聚乙烯、聚丙烯和聚氯乙烯等，代替通常的树脂胶粘剂，与超过 35%-70%以上的木粉、稻壳、秸秆等废植物纤维混合成新的木质材料，再经挤压、模压、注塑成型等塑料加工工艺，生产出的板材或型材。主要用于建材、家具、物流包装等行业。将塑料和木质粉料按一定比例混合后经热挤压成型的板材，称之为挤压木塑复合板材。
Wood plastic, namely wood plastic composite material, is a new type of composite material which is booming at home and abroad in recent years More than 35% - 70% of wood flour, rice husk, straw and other waste plant fibers are mixed into new wood materials, and then extruded, molded, injection molded and other plastic processing technologies are used to produce plates or profiles.
