可生物降解热塑性聚氨酯弹性体发泡珠粒及其制备方法
技术领域
本发明涉及一种可生物降解热塑性聚氨酯弹性体发泡珠粒及其制备方法,属于聚合物技术领域。
背景技术
热塑性聚氨酯弹性体是一类性能与加工工艺介于塑料和橡胶之间的特殊的、性能优异的、应用范围广的高分子材料。以热塑性聚氨酯弹性体为基体制备的发泡材料既保留原基体优异的性能,同时又获得优异的回弹性,可以在比较宽泛的温度范围内使用。目前,大部分发泡热塑性弹性体通过化学发泡剂进行发泡,使用这种发泡剂在造成环境污染的同时还会长时间不分解。而物理超临界发泡因环保、效率高等优势已经成为国际上的研究热点。目前热塑性聚氨酯弹性体发泡珠粒的制备工艺主要为间歇式釜压发泡和连续挤出发泡成型,制备出的发泡粒子密度低,隔热隔音、比强度高、隔热性能好,因此在包装业、工业、农业、交通运输业以及日用品等领域得到广泛应用。然而,目前热塑性聚氨酯弹性体发泡粒子分解困难,大量使用后对环境造成巨大压力,加剧了白色污染。因此,开发一种环保、可生物降解的热塑性聚氨酯弹性体发泡珠粒(ETPU)已经成为研究热点。
发明内容
针对现有技术的不足,本发明的目的是提供一种可生物降解的热塑性聚氨酯弹性体发泡珠粒,制得的发泡珠粒在保证原有的发泡倍率、强度和密度外,还能快速降解,可广泛用于包装等行业。
同时,本发明还提供其制备方法,科学合理,简单易行。

优选的,所述的生物基多元醇为PPC-PLA、PPC-PCL或PLA-PCL组合物中的一种,其中,各组合中前者与后者质量比都为1-10:9-1。
所述的异氰酸酯为4,4’二苯甲烷二异氰酸酯(MDI)、甲苯二异氰酸酯(TDI)或异佛尔酮二异氰酸酯(IPDI)中的一种。
所述的小分子醇扩链剂为1,4-丁二醇、1,3-二甲基-丙二醇或1,6-己二醇中的一种。
优选的,所述的小分子醇扩链剂为1,4-丁二醇或1,4-丁二醇与1,3-二甲基丙二醇的组合。
所述的紫外线吸收剂为2-羟基-4-正辛氧基二苯甲酮(UV-531)或2-(2’-羟基-5’-甲基苯基)苯并三氮唑(UV-P)中的一种。
优选的,所述的紫外线吸收剂为UV-531。
所述的催化剂为有机锡类或铋类催化剂中的一种。
优选的,所述的催化剂为有机锡类。
更优选的,所述的催化剂为二丁基锡二月桂酸酯、辛酸亚锡或二(十二烷基硫)二丁基锡中的一种。
所述的物理发泡剂为二氧化碳、氮气或戊烷中的一种或两种。
优选的,所述的物理发泡剂为二氧化碳。

1)将质量比例的生物基多元醇、异氰酸酯、小分子醇扩链剂、催化剂和紫外线吸收剂通过浇注机依次注入到双螺杆挤出机中;
2)在双螺杆挤出机第十温区处加入质量比例的物理发泡剂,经口模发泡后再经过水下切粒、脱水干燥得到可生物降解热塑性聚氨酯弹性体发泡珠粒。
所述的步骤1中,双螺杆挤出机分为十个温区,温度都为90-230℃;双螺杆挤出机的模温为160-210℃,水温为10-45℃。
优选的,所述的十个温区的温度为115-210℃。
优选的,所述的模温为175-205℃。
优选的,所述的水温为15-45℃。
所述的步骤2中,物理发泡剂从第十温区排气口通过高压气瓶进入双螺杆挤出机中;切粒采用切粒机进行,切粒机转速为200-4500r/min。
优选的,所述的切粒机转速为2500-3500r/min。
与现有技术相比,本发明具有如下有益效果:
1.制得的发泡珠粒具有1-8倍的发泡倍率,密度0.05-3g/cm3,耐黄变等级3-4级,收缩率0.1-1%;

对实施例1-9和对比例中的发泡珠粒性能进行表征,结果如图1所示。
表1为不同多元醇比例对可生物降解ETPU发泡珠粒性能的影响
通过对实施例与对比例进行性能分析,尽管不同比例的生物基多元醇对发泡珠粒的发泡密度、收缩率、耐黄变等级的影响规律性不强,但总体性能与PBA基的发泡珠粒性能相当,证明该可生物降解的ETPU在使用性能上达到常规要求。
受控需氧堆肥试验(根据释放出二氧化碳量计算的生物分解百分率,GB/T 19277-2003)是判断聚合物是否能够可生物降解的标准方法。45天后生物分解百分率越高,说明其降解程度越好。图1为PBA基ETPU,PCL/PLA(5:5)基ETPU,PCL/PPC(5:5)基ETPU,PPC/PLA(5:5)基ETPU的生物分解率曲线,45天后,PPC/PCL、PLA/PCL、PPC/PLA的生物分解率分别为66%,68%和71%,远远高于PBA基ETPU的生物分解率(38%)。
综上所述,生物基多元醇可有效促进ETPU的降解,对减缓白色污染起到重要的促进作用,这种可生物降解的ETPU发泡珠粒可大量应用于包装行业,代替传统的包装材料。
