Description

一种纳米陶瓷增强的高精度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，尤其涉及一种纳米陶瓷增强的高精度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。
发明内容
本发明目的就是为了弥补已有技术的缺陷，提供一种纳米陶瓷增强的高精度PVC-NBR复合发泡板及其制备方法。
本发明是通过以下技术方案实现的：

所述的一种纳米陶瓷增强的耐腐蚀性PVC-NBR复合发泡板的制备方法包括以下步骤：
（1）先将硅烷偶联剂kh560投入乙醇水溶液中，搅拌反应2-3h后加入纳米陶瓷粉，继续搅拌混合1-2h抽滤，产物水洗2-3次后干燥备用；
（2）先将NBR投入160℃密炼机中密炼20-30min，随后加入PVC、聚碳酸酯纳米微球、二甲基硅油、光稳定剂、钙锌稳定剂、环氧脂肪酸甲酯、甲基丙烯酸锌以及步骤（1）所得物料，继续密炼45-60min后得复合基料，基料自然冷却至室温备用；
（3）将步骤（2）制备的基料与其它剩余成分投入炼胶机中，在50℃条件下混炼20-30min后薄通三次后出料；
（4）将步骤（3）所得片材在模具中，在170-175℃、12-15MPa条件下热压发泡8-12min，随后卸压冷却，即得所述复合发泡板。
本发明以PVC与NBR共混材料作为复合板材基料，并加入了聚碳酸酯纳米微球，极大地提高了复合板的尺寸精度，防止板材受热变形，加入的纳米陶瓷粉经硅烷偶联剂改性后分散结合性更佳，增强增韧效果显著，有效的提高了复合板材的耐热阻燃性能，更为安全可靠，本发明最终制备的复合发泡板在热稳定性、阻燃安全性、绿色环保性、形状稳定性等方面优势突出，具有良好的应用前景。
