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50%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、注射成型等塑料加工工艺,生产出的板材或型材。木塑复合材料制品,在保证不含甲醛的绿色健康基础上,还兼具塑料和天然纤维的双重优点:既拥有天然木材的质感,同时又克服了天然木材在使用中易变形、翘裂、易霉变、受虫蚁侵害等致命缺陷,不需要复杂后期维护,使用寿命长。同时,可以通过制品的回收再处理,避免对环境造成不利影响,是真正符合国家环保政策的新型绿色建材产品。据了解,木塑复合材料的适用范围几乎可以涵盖原木、塑料、陶瓷、塑钢、铝合金及其他相似复合材料原有的使用领域,并已开始渗透入建筑、家装、家具、汽车、交通、物流、包装、园林、市政、环保、体育,甚至军 Wood-plastic composite material is a new type of composite material that is booming in recent years at home and abroad. It refers to the use of polyethylene, polypropylene and polyvinyl chloride, instead of the usual resin adhesive, with more than 50% of wood flour, rice husk, straw, etc. Waste plant fiber mixed into a new wood material, and then by extrusion, molding, injection molding and other plastic processing technology to produce the plate or profile. Wood-plastic composite products, on the basis of ensuring green and formaldehyde-free health, also has the double advantages of both plastic and natural fiber: it not only possesses the texture of natural wood, but also overcomes the defects of easy deformation and cracking of natural wood in use, Easy moldy, infested by insect atrocities and other fatal flaws, do not need complex post-maintenance, long service life. At the same time, it can be re-treated through the product recycling to avoid adverse impact on the environment, is truly in line with national environmental protection policies of new green building materials products. It is understood that the scope of application of wood-plastic composite materials can cover almost the original use of logs, plastics, ceramics, steel, aluminum and other similar composite materials, and has begun to penetrate into the construction, home improvement, furniture, automobiles, transportation, logistics , Packaging, garden, municipal, environmental protection, sports, and even the military
