目前,人们正试图用塑料薄膜模拟皮革等天然材料结构,以达到用塑料薄膜替代天然材料装饰汽车内表面的目的。汽车上的仪表板、车门内衬、车顶里衬、托架、工具箱等内装饰件都可用塑料薄膜装饰。这些部件安装位置不同,受环境(如阳光辐射)影响不同,其性能差异很大(见表1)。用在表面起修饰作用的塑料薄膜要有高的光学特性及良好的使用性能。 At present, people are trying to use plastic film to simulate natural materials such as leather structure, in order to achieve the purpose of using plastic film instead of natural materials to decorate the inner surface of the car. Car dashboards, door linings, roof linings, brackets, toolboxes and other interior trim parts are available in plastic film. These parts are installed in different locations and vary widely depending on the environment (eg, sunlight) (see Table 1). Plastic film used in the surface modification should have high optical properties and good performance.
