Description

热致变形塑料薄膜与薄片的制备方法及其产品和应用
技术领域
本发明属于复合材料技术领域,具体涉及一种热致变形塑料薄膜与薄片的制备方法及其产品和应用。
背景技术
软包装在包装印刷业中占有极其重要的位置,由塑料薄膜制做的复合包装广泛地应用于医药、食品等各个领域。为什么要进行塑料薄膜复合,因为外观上美观、轻巧、价廉,复合软包装材料柔软且携带方便,具有优异的耐高温性和耐低温性,复合粘接力强且持久,功能性强、形式多样、可用于普通、水煮、蒸煮,和传统的铁罐头相比,成本低廉、同时能提高产品的附加值。干式复合在正常工艺条件下,剥离强度(塑/塑复合)一般都在1~3.5N/15min,适合大部分产品要求。PTFE是所有聚合物当中表面自由能最低的聚合物,疏水疏油性强,PTFE对水的接触角为114°~115°,以PTFE薄膜为基材,进行干式复合是一种比较理想的选择。PTFE较低的表面能利于疏水疏油,但也不利于和其他高分子材料进行复合,所以需要选择合适的胶黏剂材料,同时PTFE复合温度较高。高模量聚酯类热塑性弹性体TPEE是以聚对苯二甲酸丁二醇酯(PBT)为硬链段,以脂肪族聚醚,例如四甲撑二醇(PTMEGT)为软链段交替组合而成的共缩聚物,具有优异的机械强度、耐热性、耐油性和耐久性,易于加工成型,故在世界各地发展较快,硬度较大,适合做结构支撑。聚己内酯PCL是一种半结晶型聚合物,其熔点为59℃~64℃,玻璃化温度为-60℃,其结构重复单元上有5个非极性亚甲基-CH2-和一个极性酯基-COO-,这样的结构使得PCL具有很好的柔韧性和加工性,这种结构特点,一方面使其具有了形状记忆性,具有初始形状的制品,经形变固定后,通过加热等外部条件刺激手段的处理,又可使其恢复初始形状的现象。使用TPEE和PCL热熔胶作为胶黏剂,一方面解决了PTFE薄膜的复合粘结问题,也具有了热致变形功能。
发明内容
