Description

一种低VOC高性能汽车内饰件专用PP复合材料及其制备方法
技术领域
本发明涉及汽车领域，具体涉及一种汽车内饰件材料及其制备方法。
背景技术
随着汽车行业对材料性能要求的不断严格，环保型低VOC材料已成为汽车用内饰材料开发的热点和方向之一。汽车内饰件一般为改性PP复合材料，其产生VOC的原因主要有：(1)PP树脂。常规高流动PP树脂一般通过有机过氧化物降解法生产，树脂内残留的过氧化物会反应生成醇、醛等有机挥发物；(2)加工助剂及其与基体PP树脂的相容性。耐热性差、与基体树脂相容差的加工助剂会通过析出、挥发产生VOC；(3)改性PP复合材料的热稳定性。PP树脂分子链会在持续的热氧化过程中部分断链降解成小分子或低分子，由此产生VOC。
目前国内对低VOC汽车专用料研究甚少，只有个别关于低气味汽车料的报道，如，中国专利《高性能低气味汽车仪表板专用聚丙烯及其制备方法》，专利申请号：200510024840.2，报道通过添加吸附剂如多孔分子筛来降低材料的低气味，但这种方式制得的产品存在吸附平衡的问题；中国专利《低散发型汽车内饰件专用料及其制备方法》，专利申请号：200810023327.5，报道通过添加有机物驱除剂如异丙醇/水来降低材料的低气味，然而这种方式存在相容性、持久性问题。
因此，如何使材料具有全面持久的低VOC排放性以及满足汽车专用料的高性能要求，将具有重要的实际应用价值，相关途径还未见报道。
发明内容
本发明的目的是针对现有技术的不足而提供一种光、热稳定性好，低VOC，具有组分少、成本低、性能好、制备容易的低VOC高性能汽车内饰件专用PP复合材料及其制备方法。
