木塑复合材料的基础为高密度聚乙烯和木质纤维，决定了其自身具有塑料和木材的某些特性。 Wood plastic composite materials for high density polyethylene and the basis of wood fiber, determines its own has some characteristics of plastic and wood. 1) 良好的加工性能 1) good processing performance 　　木塑复合材料内含塑料和纤维，因此，具有同木材相类似的加工性能，可锯、可钉、可刨，使用木工器具即可完成，且握钉力明显优于其他合成材料。机械性能优于木质材料。握钉力一般是木材的3倍，是刨花板的5倍。 Wood plastic composite containing plastic and fiber, therefore, has a similar with wood processing performance, sawing, nailing, plane, use woodworking tools to complete, and the power that grasp a hammer is superior to other synthetic materials. Mechanical performance is better than that of wood. Holding nail force is usually 3 times of wood, particle board is five times. 2) 良好的强度性能 2) good strength properties 　　木塑复合材料内含塑料，因而具有较好的弹性模量。此外，由于内含纤维并经与塑料充分混合，因而具有与硬木相当的抗压、抗弯曲等物理机械性能，并且其耐用性明显优于普通木质材料。表面硬度高，一般是木材的2—5倍。 Wood plastic composite material containing plastic, thus has good elastic modulus. In addition, due to containing fiber and blended with plastic fully, thus has with hardwood considerable physical and mechanical properties such as compressive strength, bending, and its durability is better than the ordinary wooden material. High surface hardness, average 2-5 times that of wood. 3) 具有耐水、耐腐性能，使用寿命长 3) water resistance, corrosion performance, long service life 　　木塑材料及其产品与木材相比，可抗强酸碱、耐水、耐腐蚀，并且不繁殖细菌，不易被虫蛀、不长真菌。使用寿命长，可达50年以上。 Compared with wood wood plastic materials and their products, strong acid and alkali resistance, water resistance, corrosion resistance, and do not breed bacteria, not easy to be eat by moth, not long fungus. Service life is long, can reach more than 50 years.
