Abstract

本发明公开了一种可溶剂粘接、抗扭结、透明输液管材料，由热塑性苯乙烯类弹性体、无规共聚聚丙烯、粘接促进剂、抗氧剂、润滑剂组成。本发明的输液管材料不仅具有高回弹、高强度、安全环保、不含增塑剂DEHP和重金属离子等特点，同时，特别地具有与传统PVC输液管材料相当的粘接强度、抗扭结性和透明性。

Description

可溶剂粘接、抗扭结、透明输液管材料
技术领域
本发明涉及一种输液管材料，属于高分子材料改性技术领域。
背景技术
目前，医院广泛使用的是聚氯乙烯(PVC)输液管，该类输液管中含有30～40wt％邻苯二甲酸二(2-乙基)己酯(DEHP)和一些含有钙、镁等重金属离子的稳定剂。PVC输液管在使用过程中，其中的DEHP等会吸附和溶解于脂溶性和醇溶性的药液，前者会降低疗效，增加治疗费用，后者会引起生殖系统异常，甚至有造成畸形、癌症的风险。使用后的PVC输液管的焚烧，会产生腐蚀焚烧设备的氯化氢和致癌的二噁英等气体，导致了资源的浪费和环境的污染。
热塑性苯乙烯弹性体(TPE-S)材料具有高回弹、高强度、安全环保、不含增塑剂DEHP和重金属离子等特点，是替代PVC的优选材料。但是，和PVC输液管相比，TPE-S输液管具有与其他配件粘接力小、抗扭结性差，透明度低等缺点。
发明内容
本发明的目的在于提供一种性能优异的可溶剂粘接、抗扭结、透明输液管材料。
本发明的技术解决方案是：
一种可溶剂粘接、抗扭结、透明输液管材料，其特征是：由以下重量份的组分组成：
热塑性苯乙烯类弹性体100份；
无规共聚聚丙烯35～50份；
粘接促进剂15～25份；
抗氧剂0.05～0.3份；
润滑剂0.1～1.25份。
所述的热塑性苯乙烯类弹性体为苯乙烯-乙烯/丁烯-苯乙烯嵌段共聚物、苯乙烯-乙烯/丙烯-苯乙烯嵌段共聚物、苯乙烯-乙烯-乙烯/丙烯-苯乙烯嵌段共聚物中的至少一种。
所述的热塑性苯乙烯类弹性体的苯乙烯含量为10～22wt％，其数均分子量为50,000～150,000g/mol。
所述的无规共聚聚丙烯的熔融指数为5～25g/10min。
所述的粘接促进剂为马来酸酐改性苯乙烯-乙烯/丁烯-苯乙烯嵌段共聚物、氨基改性苯乙烯-乙烯/丁烯-苯乙烯嵌段共聚物、C9石油树脂、C5石油树脂中的至少一种。
所述的抗氧剂为受阻酚类、受阻胺类、亚磷酸酯类抗氧剂中的至少一种。
所述的润滑剂为油酸酰胺、芥酸酰胺、硬脂酸、硬脂酸丁酯、乙撑双硬脂酰胺、聚乙烯蜡、硅油中的至少一种。
本发明的输液管材料不仅具有高回弹、高强度、安全环保、不含增塑剂DEHP和重金属离子等特点，同时，特别地具有与传统PVC输液管材料相当的粘接强度、抗扭结性和透明性。
下面结合实施例对本发明作进一步说明。
具体实施方式
首先将热塑性苯乙烯类弹性体、无规共聚聚丙烯、粘接促进剂、抗氧剂和润滑剂放入高混机中搅拌3分钟，转速180转/分钟。然后用长径比至少为25：1的单螺杆或双螺杆挤出机挤出造粒，加工温度范围为160～250℃。
各实施例和对比例的组分用量(重量份)见表1。性能数据见表2。
表1.实施例的组分用量
表2.实施例和对比例的性能数据
由此可以看出本发明具有优异效果。
