一种基于菌糠的PVC木塑复合材料及其制备方法
技术领域
本发明涉及复合材料技术领域，具体涉及一种基于菌糠的PVC木塑复合材料及其制备方法。
背景技术
木塑复合材料是一种新兴的复合材料，是以木纤维或植物纤维为主要原料，填充、增强，经热压复合、熔融挤出等不同加工方式制成的改性热塑性材料，主要用于建材、家具、物流包装等行业。木塑复合材料融合了“木”和“塑”的双重优点，既能克服因木材强度低、变异性大及有机材料弹性模量低等造成的使用局限性，又能充分利用废弃的木材和塑料，节能减排，减少环境污染，提升材料的附加价值，是一种极具发展前途的新型材料。尤其是随着天然资源的日益减少和需求的增加，木塑复合材料的应用领域不断扩大，技术水平随之升级，市场前景十分广阔。
菌糠是利用秸秆、木屑等原料进行食用菌栽培完成后的剩余栽培废料，在我国产量巨大，而目前并没有得到合理的回收利用。菌糠含大量的纤维素、木质素等成分，适合用于制作木塑复合材料。
