The invention discloses an improved automobile body film sticking technology. The P. film is made of body color changing film and P ET film. The thickness of the P. film is 0.15 to 0.30 mm. The P. film is set outside the body of the automobile. The heating and exhaust technology is used to force the P. film to conform closely to the body according to the streamlined shape of the automobile body. The invention effectively solves a series of problems such as difficult tearing of existing conventional adhesive tape, easy pulling down of body paint surface by hard pulling, and extremely difficult cleaning of non-adhesive tape on body paint surface when changing film, effectively remedies the shortcomings of existing conventional adhesive tape, such as easy damage, non-wear resistance, non-ability of buffering and resisting external forces, and enhances the performance of body buffering and resisting external forces. It effectively reduces the cost of changing the film on the automobile body, and significantly improves the protection ability of the outer paint surface of the automobile body and the protection ability of the life safety of the automobile body.
【技术实现步骤摘要】
一种包裹式无不干胶PET车身改色复合贴膜本专利技术涉及汽车车身贴膜领域，提供一种新型的包裹式无不干胶PET车身改色复合贴膜。本改进性专利技术可广泛用于轿车、越野车、面包车等各类中、小型汽车的车身体外贴膜。目前，国内外汽车车身贴膜均是采用带有不干胶薄膜与汽车车身漆面直接接触的方式，且厚度仅为0.04mm。因此存在着易破损，不耐磨，不具备对外部力量的安全抵抗能力，且当贴膜受损需换膜时，因不干胶与车身漆面紧紧粘合而不易撕拉，硬拉则易使车身漆面拉落。若采用专业人士通过散热枪加热撕膜方式，也会在车身漆面上留下厚厚的一层不干胶，极其不易清理等缺陷。另外其材料价格不菲、生产成本过高且实际使用效果不大也是必须面对的现实问题。本改进性专利技术目的是克服现有贴膜的不足，增加了PET抗磨层厚度，有效规避了现有贴膜因不干胶而带来的种种不利因素，充分发挥了PET改色膜耐蠕变、抗疲劳、耐摩擦、弹力好、尺寸稳定及良好的强韧性、抗张强度和抗冲击强度等优点，提供一种结构合理，既能满足现有传统常规贴膜改色美容的效果，又能有效地缓冲和抵抗外来力量的冲击、刮擦和碰撞，为车体本身安全及车内人员的人身安全提供...
