Description
技术领域
本发明涉及材料技术领域,尤其涉及一种高强度耐低温PVC手套及其制备方法。
背景技术
PVC曾是世界上产量最大的通用塑料,广泛应用在建筑材料、地板革、管材、包装膜、发泡材料等各个方面。其中PVC手套以其不易过敏、成本低、耐腐蚀、化学稳定性好等优点而占据大部分市场份额。
PVC为无定形结构的白色粉末,支化度较小,玻璃化温度77~90℃,树脂分子间是以很强的范德华力结合在一起的,刚性很强,柔软性不足,造成PVC树脂加工比较困难。为解决这些问题需要在PVC加工过程中引入增塑剂,增塑剂可以充于PVC大分子之间,使分子相互间的活动较容易,降低了聚合物分子链的结晶性,亦即增加了PVC树脂的塑性、曲绕性、柔韧性,而硬度、模量、玻璃化温度都下降,方便了PVC制品的加工成型。但是普通PVC手套加工成型后,玻璃化温度仍然很高,使得在低温下手套很硬,手感很差,难以进行精密操作。因此,研发出低温环境下仍能柔软有弹性的耐寒手套无疑具有十分重要的意义。
综上所述,目前领域内缺乏一种能满足上述技术要求的高强度耐低温PVC手套及其制备方法。
发明内容
本发明的目的在于提供一种高强度耐低温PVC手套及其制备方法。
为实现上述目的,本发明提供了一种高强度耐低温PVC手套,所述PVC手套由以下重量份的原料组成:PVC树脂100~140份、氯化聚乙烯20~40份、增塑剂55~85份、稳定剂4~12份、降粘剂5~25份、抗低温助剂20~60份。
优选地,所述增塑剂包括己二酸二辛酯、磷酸三甲酚酯、偏苯三酸三辛酯、己二酸二辛酯、癸二酸二辛酯中的一种或两种以上的组合。
优选地,所述稳定剂为液体钙锌稳定剂、硫醇丁基锡、二月桂酸二丁基锡的一种或两种以上的组合。
优选地,所述降粘剂为硬脂酸钙、硬脂酸甘油酯、石蜡中的一种或两种以上的组合。
优选地,所述抗低温助剂为硫酸钙晶须、碱式硫酸镁晶须中的一种或两种以上的组合。
优选地,所述硫酸钙晶须与碱式硫酸镁晶须的重量比为3:1。
优选地,所述PVC手套由以下重量份的原料组成:PVC树脂100~140份、氯化聚乙烯20~40份、磷酸三甲酚酯20~30份、偏苯三酸三辛酯10~20份、己二酸二辛酯25~35份、液体钙锌稳定剂4~12份、硬脂酸钙3~15份、硬脂酸甘油酯2~10份、硫酸钙晶须15~45份、碱式硫酸镁晶须5~15份。
本发明还提供一种制备高强度耐低温PVC手套的方法,所述方法包括如下步骤:
(1)将PVC树脂、增塑剂、稳定剂、抗低温助剂加入搅拌机中,在温度为60~70℃,转速为800~1000r/min的条件下,进行搅拌2~4h后,静置脱泡,制得混合料;
(2)将降粘剂、氯化聚乙烯加入步骤(1)制得的混合料中,在温度为60~70℃,转速为800~1000r/min的条件下,进行搅拌20~40min,制得浸渍液;
(3)将手模预热至70~80℃后,将手模放入步骤(2)制得的浸渍液中,将浸渍后的手模放入烤箱中,在温度为220~240℃的条件下,进行烘烤5~10min,即得。
在其中某些实施例中,所述方法包括如下步骤:
(1)将PVC树脂、磷酸三甲酚酯、偏苯三酸三辛酯、己二酸二辛酯、液体钙锌稳定剂、硫酸钙晶须、碱式硫酸镁晶须加入搅拌机中,在温度为70℃,转速为1000r/min的条件下,进行搅拌3h后,静置脱泡,制得混合料;
(2)将硬脂酸钙、硬脂酸甘油酯、氯化聚乙烯加入步骤(1)制得的混合料中,在温度为70℃,转速为1000r/min的条件下,进行搅拌30min,制得浸渍液;
(3)将手模预热至80℃后,将手模放入步骤(2)制得的浸渍液中,将浸渍后的手模放入烤箱中,在温度为240℃的条件下,进行烘烤10min,即得。
与现有技术相比,本发明具有如下有益效果:
1.本发明提供的PVC手套,不仅具有较低的玻璃化温度,能抵抗零下低温,适用于低温环境的使用;同时,本发明提供的PVC手套还保持有较高的强度以及较好的弹性,使得穿戴者更加舒适。
