Description
技术领域
本发明主要涉及一种复合型材，尤其涉及一种防腐木塑复合型材。
背景技术
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。
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。
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。
通过助剂，塑料可以发生聚合、发泡、固化、改性等改变，从而改变木塑材料的密度、强度等特性，还可以达到抗老化、防静电、阻燃等特殊要求。
具有紫外线光稳定性、着色性良好。其最大优点就是变废为宝，并可100%回收再生产。
可以分解，不会造成“白色污染”，是真正的绿色环保产品。
原料来源广泛，生产木塑复合材料的塑料原料主要是高密度聚乙烯或聚丙烯，木质纤维可以是木粉、谷糠或木纤维，另外还需要少量添加剂和其他加工助剂。还可以根据需要，制成任意形状和尺寸大小。
