TPU热熔胶膜是一种应用到生活及工业生产常见的热熔胶产品，常温状态为固态没有粘性，高温状态会熔化，双面具有粘性，属于环保型胶粘剂。具有很高的抗拉强度、极佳的柔软弯曲性、耐候性、透明性，与人体接触舒适、易加工，与各种材质粘合强度高。广泛应用于冲锋衣，运动面料，商标织唛，绣花，烫画以及纺织品等各类材料的粘接。TPU热熔胶膜需要具有优良的耐水洗性能，面料经过热熔胶膜粘接后，经过一定温度的水浸泡和反复揉搓，还能保持较高的粘接强度。现有TPU热熔胶膜的耐紫外光老化较差，限制了应用领域。
发明内容

对上述技术方案的进一步改进为，所述紫外光稳定剂为聚丁二酸(4-羟基-2,2,6,6-四甲基-1-哌啶乙醇)酯或双(2,2,6,6-四甲基-4-哌啶基)癸二酸酯。
对上述技术方案的进一步改进为，所述紫外光吸收剂为金红石型二氧化钛、气相二氧化硅的混合物，所述金红石型二氧化钛、气相二氧化硅的质量比为1-2：1-2。
一种耐紫外光老化TPU热熔胶膜的制备方法，包括如下步骤：
