Abstract
本发明公开了耐油污高耐磨防紫外线的PET防爆膜，包括PET基材，PET基材一侧还形成有防爆层，防爆层的厚度为3‑4μm,PET基材另一侧形成有亚克力胶层，亚克力胶层的干胶厚度为20‑25μm。本发明的防爆膜有效改善了对紫外线的防护性能，并且具有良好的贴合性能。
Description
技术领域
本发明是关于紫外防护材料技术，特别是关于一种耐油污高耐磨防紫外线的PET防爆膜。
背景技术
近年来，随着汽车行业、建筑行业的兴起，人们在满足了生活物质需求的同时，开始更加关注身体的健康。紫外线作为一种特殊的物质，它对人体照射后会使皮肤变黑，皮肤有明显的色素沉着，长时间照射会刺激皮肤，严重的会导致皮肤癌。现在的汽车窗膜、办公室玻璃保护膜等只是简单隔离光照，并不能防止紫外线进入。
公开于该背景技术部分的信息仅仅旨在增加对本发明的总体背景的理解，而不应当被视为承认或以任何形式暗示该信息构成已为本领域一般技术人员所公知的现有技术。
发明内容
本发明的目的在于提供一种耐油污高耐磨防紫外线的PET防爆膜，通过采用独特的涂层设计和结构设计有效改善了产品的紫外防护、耐油污、耐磨等多方面的性能。
为实现上述目的，本发明的实施例提供了耐油污高耐磨防紫外线的PET防爆膜，包括PET基材，PET基材一侧还形成有防爆层，防爆层的厚度为3-4μm,PET基材另一侧形成有亚克力胶层，亚克力胶层的干胶厚度为20-25μm。
在本发明的一个或多个实施方式中，防爆层的原料包括，以重量份数计：乙酸丁酯或乙酸乙酯17-19％，分散剂0.2-0.3％，热稳定剂0.2-0.3％，光感剂4-5％，钴源0.1-1％，以表面活性剂预处理过的空心微珠5-6％，聚异氰酸酯7-9％，余量为970丙烯酸树脂。
在本发明的一个或多个实施方式中，空心微珠的预处理为以磺酸盐型阴离子表面活性剂充分浸润得到。
在本发明的一个或多个实施方式中，防爆层在PET基材上的涂布量为0.3-0.5g/m2。
在本发明的一个或多个实施方式中，光感剂为二苯甲酮、苯乙酮、二乙氧基苯乙酮、苯偶姻异丙醚、N-甲基二乙醇胺二苯甲酮、2-羟基-甲基-1-苯基丙-1-酮、2-苄基-2-(二甲基氨基)-1-[二甲基氨基]-1-[4-(4-吗啉基)苯基]-1-丁酮或二苯基(2,4,6-三甲基苯甲酰基)氧化膦中的一种或几种的混合物。
在本发明的一个或多个实施方式中，热稳定剂为钡皂、镉皂、锌皂、有机亚磷酸酯中的一种或几种的混合物。
在本发明的一个或多个实施方式中，分散剂为微晶石蜡、低分子蜡、硬脂酸钡中的一种或几种的混合物。
在本发明的一个或多个实施方式中，钴源为有机钴。有机钴的导入除增加与材料主体融合性的同时，还通过钴原子增强光吸收与散射效率，从而增强防护性能。
在本发明的一个或多个实施方式中，防爆膜还设置有与亚克力胶层贴合的离型层。
与现有技术相比，根据本发明实施方式的耐油污高耐磨防紫外线的PET防爆膜，耐油污高耐磨防紫外线防爆层的厚度为3-4μm，一次涂布实现耐磨、防污、防紫外线的功效，保证膜的品质，避免多次涂布导致生产工序复杂、生产成本高。高粘亚克力胶层的厚度为20-25μm，防爆膜的抗耐磨性好，使用寿命长，防紫外性能高，整体性能良好。
附图说明
图1是根据本发明一实施方式的结构示意图。
具体实施方式
下面结合附图，对本发明的具体实施方式进行详细描述，但应当理解本发明的保护范围并不受具体实施方式的限制。
除非另有其它明确表示，否则在整个说明书和权利要求书中，术语“包括”或其变换如“包含”或“包括有”等等将被理解为包括所陈述的元件或组成部分，而并未排除其它元件或其它组成部分。
