The invention relates to a high-performance automobile window film. The automobile window film is an ABC type three-layer co-extrusion structure film; wherein the layer A is an outer surface layer, the layer B is a middle layer, and the layer C is an inner surface layer; each of the layer A and the layer C is prepared from the following raw materials in percentage by mass: 60-70% of PET (Polyethylene Terephthalate) resin slices, 20-30% of modified PET resin slices and 10-15% of an additive; and the layer B is made of PET (Polyethylene Terephthalate) resin slices. The automobile window film disclosed by the invention not only has excellent optical properties such as high transmission, low reflection and low haze, but also has excellent use properties such as high temperature resistance, heat insulation, wear resistance, static electricity resistance and adhesion resistance, and can meet the long-term use requirements of automobile windows under harsh conditions.

    本发明涉及一种高性能汽车车窗薄膜,所述汽车车窗薄膜为ABC型三层共挤出构造薄膜;其中,A层为外表层,B层为中间层,C层为内表层;所述A层和C层材料均由以下质量百分含量的原料组成:60~70%PET树脂切片,20~30%改性PET树脂切片和10~15%添加剂;所述B层材料为PET树脂切片。本发明的汽车车窗薄膜,不仅具有高透射、低反射和低雾度等优异光学性能,而且具有耐高温、隔热、耐磨、抗静电和抗粘连等优异使用性能,可满足汽车车窗在严苛条件下的长期使用要求。
