S2、保护膜的制备，将步骤S1制备所得的PET基材通过复合工艺将自粘层、丙烯酸胶水层、防刮涂层和防粘背层与PET基材进行复合制备，且自粘层由80％～90％的SEBS和10％～20％的聚烯烃塑性体树脂制备而成，且通过将SEBS与聚烯烃塑性体树脂放入混料机中进行搅拌，且搅拌时间为10-20分钟，混合均匀后通过环形模头挤出膜管，有压缩空气将其冷却定型，且防刮涂层的制备工艺与自粘层制备的工艺相同，然后在防刮涂层和PET基材之间涂覆丙烯酸胶水层，使得两者贴合，将二氧化硅与聚丙烯充分混合后经挤出机挤出、干燥、切粒制成防粘背层；
S3、成型制备，将步骤S2中所制备的，自粘层、防刮涂层和防粘背层通过真空蒸镀法将与步骤S1中制备的PET基材进行加工，使得制备出反光材料的保护膜。
优选的，步骤S2中，SEBS是以聚苯乙烯为末端段，以聚丁二烯加氢得到的乙烯-丁烯共聚物为 中间弹性嵌段的线性三嵌共聚物。
