Description
技术领域
本发明涉及PVC热稳定剂技术领域,具体涉及一种基于多元醇酯金属配合物的PVC热稳定剂。
背景技术
聚氯乙烯(PVC)具有耐腐蚀、难燃、绝缘性能好等特点,广泛用于建筑、医疗卫生、日用化工及农业等领域。PVC大多是通过自由基聚合,然而自由基聚合的PVC产物,分子链中不可避免地存在不稳定的缺陷结构,如烯丙基氯、叔氯等,导致PVC在加工的条件下极易降解脱除出HCl气体,即PVC的分解温度低于加工温度。同时,脱除的HCl对PVC的降解具有催化作用,在加工中由于剪切力的作用,会加速PVC的降解,使得最终的制品色泽不佳,并且力学性能下降,降低了使用价值。因此,热稳定剂是PVC塑料成型过程中必不可少的添加剂。
常用的PVC热稳定剂有铅盐类、金属皂类、有机锡类、稀土类稳定剂等。随着人们环保意识的增强和性能要求的提高,单一的热稳定剂已不能满足PVC加工要求,热稳定剂逐渐向无毒、环保、复合方向发展。其中,Ca/Zn及其复合热稳定剂属于一种无毒、环保型热稳定剂,具有价格低廉、润滑性良好等优点,受到了广泛关注。
锌基热稳定剂是一种极好的初期热稳定剂,虽然早期能保持较高的白度,但是生成的氯化锌易加速PVC的降解,引起“锌烧”。而多元醇类辅助热稳定剂能够络合金属离子以很好的延缓“锌烧”,将多元醇与锌基热稳定剂结合,得到的多元醇锌基热稳定剂对PVC的热稳定取得了明显效果。然而多元醇类(如季戊四醇、双季戊四醇等)在后期容易析出,使得制品性能下降,且加工过程中由于熔点高、极性大与PVC的相容性较差,容易分散不均。
CN20111009669.7公开了一种改性锌基热稳定剂的制备方法。将季戊四醇和氧化锌按一定的质量比粉碎后加热到140-180℃,搅拌反应4-6h,冷却粉碎后即得改性锌三盐,该锌三盐的热稳定效果很好,但是熔点高,与PVC相容性较差。
陈肇汉等[1]将合成的季戊四醇锌与环氧大豆油、水滑石、β-二酮复配表现出很好的协同效果,但是初期白度较差。([1]陈肇汉等.季戊四醇锌的合成及其在型材稳定剂中的应用[J].广东化工,2013,40(15):59-61)
许士鲁等[2]将季戊四醇锌分别与硬脂酸钙、水滑石、环氧大豆油及β-二酮复配,其中季戊四醇锌与硬脂酸钙或β-二酮复配时没有明显的协同效应,与水滑石复配后的初期热稳定性能较差。([2]许士鲁,李德刚,于先进等.PVC新型无毒热稳定剂季戊四醇锌的合成及应用研究.中国塑料,2011,25(5):90-95.)
陈煥章等[3]将活性氧化锌和季戊四醇反应得到季戊四醇锌,通过对比其与硬脂酸钙、硬脂酸钙及硬脂酸锌复配应用于PVC的效果,发现季戊四醇锌的热稳定性能比硬脂酸锌的热稳定性能相对更好。([3]陈煥章,李花,李宏等.季戊四醇锌热稳定剂的制备与应用.中国塑料,2015,29(10):78-82.)
上述工作均以活性氧化锌和季戊四醇为原料通过固相反应合成了季戊四醇锌,并用于PVC稳定体系,取得了较好效果,但是并没有解决热稳定剂与PVC基体相容性差的问题。
