Description
技术领域
本发明涉及一种适用于PVC材料的复配助剂。
背景技术
聚氯乙烯(PVC)是氯乙烯单体在过氧化物、偶氮化合物等引发剂或在光、热作用下按自由基聚合反应机理聚合而成的聚合物，PVC是使用最广泛的塑料材料之一，人们发现PVC塑料只有在160℃以上才能加工成型，而它在120-130℃时就开始分解，释放出HCl气体，如果不抑制HCl产生，分解又会进一步加剧，这一问题曾是困扰PVC塑料的开发与应用的主要难题。
PVC塑料制品品种较多，但有些产品给人一种不耐用的印象，如果在户外使用，寿命会更短，PVC本身结构存在很多弱点，残留引发剂，端基金属杂质，含氧结构，丙烯基氯，聚合度，分子量分布等都会对PVC性能产生影响，这些不稳定因素在光，热，氧，助剂，HCl等作用下易老化，即降解或交联，使其物理机械性能变坏，失去应用价值。
发明内容
为解决上述技术问题，本发明提供一种能提高PVC加工及使用过程中的抗氧化性，稳定性以及耐候性的复合助剂。
为实现上述目的，本发明采用的技术方案是：一种用于PVC的复配助剂，由以下原料按重量份配比组成：
所述主抗氧剂为受阻胺类抗氧化剂或受阻酚类抗氧化剂。
所述辅助抗氧剂为分子量为600-1200的亚磷酸酯类抗氧剂。
所述螯合剂为分子量为200-700的亚磷酸酯类化合物。
优选的，上述的一种用于PVC的复配助剂，所述主抗氧剂选自受阻酚类抗氧剂。
优选的，上述的一种用于PVC的复配助剂，所述受阻酚类抗氧剂选自抗氧剂1010、双酚A、抗氧剂1076或抗氧剂3114的一种或二种以上的组合。
优选的，上述的一种用于PVC的复配助剂，所述亚磷酸酯类抗氧剂选自抗氧剂168、抗氧剂626或抗氧剂618的一种或二种以上的组合。
优选的，上述的一种用于PVC的复配助剂，所述亚磷酸酯类化合物选自亚磷酸三苯酯、亚磷酸三酯或亚磷酸苯基二酯的一种或二种以上的组合。
优选的，上述的一种用于PVC的复配助剂，按质量比，2-乙基己酸锌:硬脂酸钡:碳酸钙＝(1.2-2):(1.5-2):1。
优选的，上述的一种用于PVC的复配助剂，按质量比，主抗氧剂：辅助抗氧剂＝2-3:1。
优选的，上述的一种用于PVC的复配助剂，按质量比，硬脂酸钡:螯合剂＝3-4:1。
本发明提供的一种用于PVC的复配助剂在制备PVC材料中的应用。
优选的，所述用于PVC的复配助剂的添加量为PVC重量的0.3-1.0％。
本发明的有益效果是：
1、本发明用于PVC的复配助剂，各组分均为无毒物质，健康环保。
2、本发明用于PVC的复配助剂，各组分方便易得，且有良好经济性。
3、本发明用于PVC的复配助剂，添加方式自由，用于PVC材料时可直接混合也可混合造粒后添加。
4、本发明用于PVC的复配助剂，稳定剂、螯合剂与抗氧剂协同发挥作用，对PVC的生产，加工，存储和应用产生稳定的保护作用。
5、本发明用于PVC的复配助剂，是一种高效、低成本、无粉尘污染及无毒或低毒的新型复配助剂，该助剂即具有抗氧化剂的抗氧化作用，又具有稳定剂的稳定作用，并显著提高树脂耐候性和加工过程中及使用过程中的耐候性及稳定性.
