Description

一种含纳米碳纤维的高强高弹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碳纤维的高强高弹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，提供一种含纳米碳纤维的高强高弹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：
一种含纳米碳纤维的高强高弹PVC-NBR复合发泡板，该复合发泡板由以下重量份的原料制得：PVC 40-50、NBR 20-25、AC发泡剂2-5、聚己内酯5-6、天然乳胶10-15、纳米碳纤维0.4-0.5、硼酸三乙酯1-2、促进剂TMTD 0.4-0.5、硬脂酸0.5-1、大豆油2-3、硫化剂PDM 1-1.5、光稳定剂0.5-1、钙锌稳定剂4-5、氧化锌3-4、硅烷偶联剂kh560 0.5-1、环氧脂肪酸甲酯5-8、甲基丙烯酸锌2-4、80-90%的乙醇水溶液10-15。
所述的一种含纳米碳纤维的高强高弹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后加入纳米碳纤维，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、天然乳胶投入150℃密炼机中密炼20-30min，随后加入PVC、聚己内酯、氧化锌、环氧脂肪酸甲酯、大豆油、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30-40min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155-160℃、15-18MPa条件下热压发泡20-25min，随后卸压冷却，即得所述复合发泡板。
本发明以PVC与NBR、天然乳胶、聚己内酯等高分子材料共混作为发泡树脂基料，使得该复合发泡板具有极高的回弹性和韧性，加入的经硅烷偶联剂改性处理后的纳米碳纤维进一步极大地提高了发泡板的强度和耐热稳定性，再结合其它原料，最终制备得到了具有天然乳胶质感的高弹、抗蠕变、抗断裂、环保的复合发泡板，在高档家装材料方面有突出的市场优势。
