Abstract

本发明公开了一种环保高白度耐老化投影PVC膜，其原料按重量百分数如下：聚氯乙烯树脂48‑50%，对苯二甲酸二辛酯20%，环氧大豆油2%，填充剂8%，钙锌稳定剂2.5‑3%，抗紫外线剂2%，抗氧化剂2%，色料0.5%，高白度金红石型二氧化钛14‑16%。通过使用聚氯乙烯树脂、高白度金红石型二氧化钛、抗氧化剂和抗紫外线剂，大大提升此PVC膜的拉力强度、遮光率、白度、抗老化、抗紫外线效果。

Description

环保高白度耐老化投影PVC膜
技术领域
本发明属于高分子材料的新型加工和应用技术领域，更具体地说，尤其涉及一种环保高白度耐老化投影PVC膜。
背景技术
PVC合成薄膜在广泛使用，一般的PVC薄膜强度差，遮光率、白度均一般，也没有抗紫外线的效果，达不到客户使用要求，使用时间大大缩短。
发明内容
本发明的目的在于提供一种环保高白度耐老化投影PVC膜，以解决上述背景技术中提出的问题。
为实现上述目的，本发明提供如下技术方案：
一种环保高白度耐老化投影PVC膜，其原料按重量百分数如下：聚氯乙烯树脂48-50%，对苯二甲酸二辛酯20%，环氧大豆油2%，填充剂8%，钙锌稳定剂2.5-3%，抗紫外线剂2%，抗氧化剂2%，色料0.5%，高白度金红石型二氧化钛14-16%。
优选的，所述抗紫外线剂和抗氧化剂的质量比为1：1。
优选的，所述高白度金红石型二氧化钛的白度不低于氧化镁的白度。
与现有技术相比，本发明的有益效果是：通过使用聚氯乙烯树脂、高白度金红石型二氧化钛、抗氧化剂和抗紫外线剂，大大提升此PVC膜的拉力强度、遮光率、白度、抗老化、抗紫外线效果。
具体实施方式
为了使本发明的目的、技术方案及优点更加清楚明白，以下结合具体实施例，对本发明进行进一步详细说明。应当理解，此处所描述的具体实施例仅仅用以解释本发明，并不用于限定本发明。
一种环保高白度耐老化投影PVC膜，其原料按重量百分数如下：聚氯乙烯树脂48-50%，对苯二甲酸二辛酯20%，环氧大豆油2%，填充剂8%，钙锌稳定剂2.5-3%，抗紫外线剂2%，抗氧化剂2%，色料0.5%，高白度金红石型二氧化钛14-16%。
具体的，所述抗紫外线剂和抗氧化剂的质量比为1：1。
具体的，所述高白度金红石型二氧化钛的白度不低于氧化镁的白度。
本发明还提供了一种环保高白度耐老化投影PVC膜的制备工艺，将原料的重量百分数数值输入到自动计量设备中，自动计量设备量取物料，并将物料添加到高速混合机中混合20-30min，然后送入万马力密炼机中密炼30-40min，使用胶化轧轮机进行连续压轧，通过过滤机过滤后送入五辊压延机压延成型，并在需要压花的位置压制花纹，冷却定型后卷取包装。
本发明通过将现有的乙烯法树脂和该配方工艺相结合，增强了该PVC膜的强度、遮光率呵呵白度。
以上所述，仅为本发明较佳的具体实施方式，但本发明的保护范围并不局限于此，任何熟悉本技术领域的技术人员在本发明揭露的技术范围内，根据本发明的技术方案及其发明构思加以等同替换或改变，都应涵盖在本发明的保护范围之内。
