Description

一种高疏水抗粘的PVC-NBR复合发泡板及其制备方法
技术领域
本发明涉及PVC发泡板技术领域，尤其涉及一种高疏水抗粘的PVC-NBR复合发泡板及其制备方法。
背景技术
PVC发泡板具有防水、阻燃、耐酸碱、防蛀、质轻、保温、隔音、减震等特性，是木材、铝材、复合板材的理想替代品，广泛的应用于客车、火车车厢顶棚、箱体芯层、内部装潢用板、建筑物外墙板、内装饰用板、办公室、住宅、公共场所建筑物隔间，商用装饰架、无尘室用板、吊顶板等方面。
尽管PVC发泡板具有如此广泛的应用空间，然而其实际市场占有率却偏低，尤其在家装材料方面，主要的制约因素是产品良莠不齐，产品在强度、刚性、热稳定性等方面不尽如人意，使用时存在安全隐患，为了提高PVC板材的综合性能，使用高分子材料和无机填料共混改性是最常用的方法。《阻燃型NBR/PVC发泡材料的研究》一文将NBR与PVC共混发泡，获得了力学性能较为优良的产品，但是其耐热性差，需添加阻燃剂达到阻燃效果，但是对材料的力学性能影响较大，使用受到限制。
