Abstract
本发明公开了一种亚光聚氯乙烯材料及其制备方法，该材料是由以下重量份的组分制成：PVC 100份，DOP 80～90份，复合稳定剂4～6份，硬脂酸钡1.6～2.0份，粉末丁腈胶16～20份，促进剂1.4～1.8份，硫磺1.8～2.0份，轻质碳酸钙60～70份。本发明在配方中加入粉末丁腈胶，使得组合成分在挤出制备过程中与PVC发生动态交联反应，取得类似橡胶状的亚光效果。
Description
技术领域
本发明属于化工技术领域，涉及一种亚光聚氯乙烯材料及其制备方法。
背景技术
聚氯乙烯(PVC)是一种综合性能较好的通用塑料，特别是添加大量增塑剂后得到类似橡胶的聚氯乙烯弹性体，综合性能较好，但表面光亮度太高，没有橡胶状的亚光。目前一般用高聚合度PVC树脂或部分交联PVC树脂，但亚光效果不明显。
发明内容
本发明的目的是克服上述不足之处提供一种亚光聚氯乙烯材料。
本发明的另一目的是提供该亚光聚氯乙烯材料的制备方法。
本发明的目的是通过以下方式实现的：
一种亚光聚氯乙烯材料，该材料是由以下重量份的组分制成：
上述材料优选是由以下重量份的组分制成：
上述材料最优选是由以下重量份的组分制成：
PVC是由PVC SG-5和PVC SG-3按照1：1的重量比混合组成。
促进剂是由促进剂TMTD和促进剂CZ按照0.2～0.3：1.2～1.5的重量比混合组成。粉末丁腈胶平均粒径40～60目，丙烯腈含量33(％)，优选为粉末丁腈胶P83。
复合稳定剂为铅盐复合稳定剂。
上述亚光聚氯乙烯材料的制备方法包括以下步骤：
先将PVC、DOP、复合稳定剂、硬脂酸钡搅拌12～13分钟，再加入粉末丁腈胶、促进剂、硫磺、轻质碳酸钙、炭黑搅拌20～40秒后冷却至室温，再在长径比为36:1的双阶混炼机组上挤出造粒，各区温度设定如下：
轻质碳素酸钙在本发明配方中起到填充作用，硫磺在配方中起到交联作用。
与现有技术比较本发明的有益效果：本发明在配方中加入粉末丁腈胶，使得组合成分在挤出制备过程中与PVC发生动态交联反应，取得类似橡胶状的亚光效果。本发明使用TMTD和CZ的混合促进剂兼顾了工艺性、机械性能，能够进一步促使PVC与丁腈胶发生反应，使得交联更均匀、更可控。
具体实施方式
以下通过具体实施方式对本发明进行进一步说明：
实施例1
制备方法：
1、高速混合：先将PVC、DOP、复合稳定剂、硬脂酸钡搅拌12分钟，再加入P83粉、促进剂、硫磺、轻质碳酸钙和炭黑搅拌半分钟后放入存粉箱冷却至室温备用。
2、挤出：在长径比为36:1的双阶混炼机组上挤出造粒，各区温度设定如下：
以下为本发明实施例1制备得到的亚光聚氯乙烯材料和普通聚氯乙烯材料性能对比表，从表中对比数据可以看到，本发明亚光聚氯乙烯材料的拉伸强度、断裂伸长率性能均显著提高的同时，镜面光泽可低至35％。
实施例2
制备方法：
1、高速混合：先将PVC、DOP、复合稳定剂、硬脂酸钡高速搅拌13分钟，再加入P83粉、促进剂、硫磺、轻质碳酸钙和炭黑搅拌半分钟后放入存粉箱冷却至室温备用。
2、挤出：在长径比为36:1的双阶混炼机组上挤出造粒，各区温度设定如下：
以下为本发明实施例2制备得到的亚光聚氯乙烯材料和普通聚氯乙烯材料性能对比表，从表中对比数据可以看到，本发明亚光聚氯乙烯材料的拉伸强度、断裂伸长率性能均显著提高的同时，镜面光泽可低至35％。
