Description

一种含纳米硅藻土的具有净化空气功效的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，尤其涉及一种含纳米硅藻土的具有净化空气功效的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。
发明内容
本发明目的就是为了弥补已有技术的缺陷，提供一种含纳米硅藻土的具有净化空气功效的PVC-NBR复合发泡板及其制备方法。

所述的一种含纳米硅藻土的具有净化空气功效的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后加入纳米硅藻土，混合研磨分散40-50min后抽滤，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20-25min，随后依次加入PVC、醋酸纤维素、聚乙二醇、β-环糊精、碳酸钙、环氧脂肪酸甲酯、光稳定剂、钙锌稳定剂、甲基丙烯酸锌以及步骤（1）所得物料，继续密炼40-50min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160-165℃、10-15MPa条件下热压发泡20-30min，随后卸压冷却，即得所述复合发泡板。
本发明以PVC与NBR、醋酸纤维素、聚乙二醇等原料共混作为复合发泡基料，该复合基料各原料间具有良好的相容性和结合性，易于发泡塑性，加入的经硅烷偶联剂改性后纳米硅藻土易于分散，其良好的吸附性赋予复合板材净化空气的能力，再结合其它材料，最终制得了表面爽滑、耐热透气、环保无毒的复合发泡板，在多个领域均具有良好的应用价值。
