Description

一种木塑复合型材
技术领域
本发明属于材料科学技术领域，尤其涉及一种木塑复合型材。
背景技术
木塑复合材料具有木材和塑料的双重特性，并且这种材料有耐腐蚀、耐磨、不翘曲、尺寸稳定、机械性能良好、外观与木材相似的优点。以木塑复合材料来代替木材，不仅可减少对木材的需求量，节约森林资源，而且通过对废弃资源的综合开发利用，变废为宝，有很高的经济与社会效益。
尽管木塑复合材料具有许多优点，但由于树脂与木粉的复合，一方面其韧性、冲击强度和弯曲强度等力学性能相对未填充的塑料会有所降低，另一方面相对天然木材来说，密度是木制品的两倍左右，不能作为理想的木材替代品，因此其应用领域受到了一些限制。向木塑复合材料的原料中加人发泡剂进行发泡挤出，经发泡后的木塑复合材料存在良好的泡孔结构，可钝化裂纹尖端并有效阻止裂纹的扩张，从而显著提高了材料的抗冲击性能和韧性。制品密度接近于木材，而机械强度高于木材，这使其可作为良好的木材替代品，而且产品成本降低，从而进一步拓宽了木塑复合材料的应用范围。
发明内容
为解决上述现有的技术问题，本发明采用如下方案：
一种木塑复合型材，其原料及原料重量百分含量如下：
PVC 40-50％；
发泡剂0.1-1％；
偶联剂0.1-3％；
抗静电剂0.1-3％；
天青石0.1-3％；
木粉 40-60％。
本发明具有防霉、耐候、抗静电的特点。
具体实施方式
下面将结合具体实施例来详细说明本发明，在此本发明的示意性实施例以及说明用来解释本发明，但并不作为对本发明的限定。
实施例
本发明所述一种木塑复合型材，其原料及原料重量百分含量如下：PVC 45％、发泡剂0.5％、偶联剂0.5％、抗静电剂1％、天青石2％、木粉 51％。
上述实施例仅例示性说明本发明的原理及其功效，而非用于限制本发明。任何熟悉此技术的人士皆可在不违背本发明的精神及范畴下，对上述实施例进行修饰或改变。因此，举凡所属技术领域中具有通常知识者在未脱离本发明所揭示的精神与技术思想下所完成的一切等效修饰或改变，仍应由本发明的权利要求所涵盖。
