Description

一种大型油囊水囊用TPU复合面料
技术领域
本发明TPU复合面料技术领域，具体涉及一种可用于制作大型油囊或水囊的TPU复合面料。
背景技术
油囊水囊是用于储存和输送油、水待液体货物的工具。该类工具要求其材料本身应当具有高强度、高弹性以及优良的耐油性和耐水性，适应环境的性能强。公开号为CN104527190 A的中国发明专利申请公开了一种储油囊用TPU复合材料，该申请中指出：传统的储油囊用TPU复合材料多是采用聚酯型TPU材料，虽具有优异的耐油性，但是耐水解性差，耐寒性能－25至－30℃，同时，材料的撕裂强度受到胶水的影响耐降低，影响到材料的使用性能，产生安全隐患。于是，该申请提出的技术方案是：采用水性聚氨酯涂层剂对纤维网进行改性处理，以提高PU胶水在纤维表面的附着力，从而提高复合材料的剥离强度；同时，选用聚醚型TPU树脂为原料提高复合材料的耐水解性。该技术方案虽然相比传统的复合材料在耐水性能上有所改进，但其耐水性能仍然不能达到大型水囊的使用要求。
发明内容
本发明的目的在于克服上述现有技术的缺陷，提供一种大型油囊水囊用TPU复合面料，其同时兼职了耐油性和耐水解性，同时也具有较高的剥离强度，既适用于大型油囊也适用于大型水囊。
为实现上述目的，本发明采用如下技术方案：
一种大型油囊水囊用TPU复合面料，其由上至下依次包括聚酯型TPU面膜层、第一胶水粘合层、纤维布层及第二胶水粘合层、聚醚型TPU底膜层，所述纤维布层经过电晕处理。
进一步的，所述聚酯型TPU面膜层按质量百分数计包括，聚酯型TPU 83～87％、三元乙丙橡胶2～8％、聚碳化二亚胺3～10％、色母0.5～2％及碳酸钙0.1～1％。
进一步的，所述第一胶水粘合层和第二胶水粘合层均为PUR热熔胶层。
进一步的，所述聚醚型TPU底膜层按质量百分数计包括，聚醚型TPU 80～90％、丙烯酸酯类单体5～15％、碳酸钙3～10％。
进一步的，本发明的大型油囊水囊用TPU复合面料，采用以下方法制备而成：
1)取纤维布布置在电晕辊上进行第一次电晕；
2)第一次电晕完成后，将纤维布未电晕的表面布置在电晕辊上与电晕辊接触，进行第二次电晕；
3)在纤维布的上下表面上均涂覆上PUR热熔胶；
4)制备聚酯型TPU面膜，按重量百分数计，取聚酯型TPU 83～87％、三元乙丙橡胶2～8％、聚碳化二亚胺3～10％、色母0.5～2％及碳酸钙0.1～1％混匀后干燥，然后流延加工成聚酯型TPU面膜；
5)制备聚醚型TPU底膜，按质量百分数计，取聚醚型TPU 80～90％、丙烯酸酯类单体5～15％、碳酸钙3～10％混匀后干燥，然后流延加工成聚醚型TPU底膜；
6)将涂覆了PUR热熔胶的纤维布用热风预热后，再在表面和底面分别贴合聚酯型TPU面膜和聚醚型TPU底膜。
与现有技术相比，本发明的有益效果是：
本发明对聚酯型TPU材料进行了改性，采用三元乙丙橡胶和聚碳化二亚胺两种材料混合聚酯型TPU制成的薄膜，同时具有较强的耐油性和耐水解性能，结合聚醚型TPU薄膜，使得复合而成的面料耐油性和耐水解性能进一步增强，同时对纤维布进行电辊处理后再与PUR热熔胶结合，增强了复合面料的剥离强度，使得复合面料综合性能好，可以用于制作油囊或者水囊。
