Description

一种光稳定性好的汽车装饰膜制备工艺
技术领域
本发明涉及装饰膜制备技术领域，尤其涉及一种光稳定性好的汽车装饰膜制备工艺。
背景技术
新能源电动汽车，新能源电动汽车的组成包括：电力驱动及控制系统、驱动力传动等机械系统、完成既定任务的工作装置等。
电力驱动及控制系统是电动汽车的核心，也是区别于内燃机汽车的最大不同点。电力驱动及控制系统由驱动电动机、电源和电动机的调速控制装置等组成。电动汽车的其他装置基本与内燃机汽车相同。
随着社会的发展，家用电器、汽车、手机等部件都大量采用了塑料件，其表面装饰的要求越来越高。目前，塑料件表面金属化装饰采用电镀、真空沉积工艺和热转印箔。电镀工艺生产环境较差，对工人健康不利，且对塑料件的要求较高，很多领域已不再采用。真空沉积工艺近年来在薄膜领域进展较快，但对成型塑件的加工费用较高。而转印膜为干法加工工艺，可实现多种装饰效果，有利于环保，适用于大部分家电、汽车、手机等部件。
汽车装饰膜是用于装饰汽车表面或者内部的薄膜，现在的装饰膜长期使用后，薄膜将会出现褪色的状况，影响车体美观度。
发明内容
本发明的目的是为了解决现有技术中汽车装饰膜易褪色的缺点，而提出的一种光稳定性好的汽车装饰膜制备工艺。
为了实现上述目的，本发明采用了如下技术方案：
设计一种光稳定性好的汽车装饰膜制备工艺，包括以下步骤：
步骤一：称取如下重量份原料：ASA胶粉20-30份、PMMA15-20份、硅酮树脂2-3份、氯化石蜡0.3-0.5份、氧化锌0.5-0.8份、硅酮粉1-1.7份、粘合剂2-3份、增韧剂1.5-2.5份、二氰二氨1.2-1.5份、色粉1.5-2.5份；
步骤二：将硅酮树脂、氯化石蜡、氧化锌、硅酮粉、粘合剂、增韧剂、二氰二氨、色粉进行预混5-7分钟，然后将ASA胶粉、PMMA加入，进行高混10-15分钟；
步骤三：然后进行密炼，密炼之后通过螺杆挤出机挤出；
步骤四：将挤出的胶体通过四辊压延机压延，通过测厚仪测量薄膜厚度，然后进行牵引、电晕处理、收卷。
优选的，所述粘合剂为钛酸酯偶联剂，所述增韧剂为丙烯酸酯，所述色粉为钛白粉、碳黑、钛黄粉、酞酞菁绿一种或数种的混合物。
优选的，螺杆挤出机为三螺杆挤出机。
优选的，密炼时，密炼时间16-18分钟、温度210-230℃、真空度小于-0.03MPa。
本发明提出的一种光稳定性好的汽车装饰膜制备工艺，有益效果在于：本产品能够将薄膜的颜色固化，有效防止薄膜在太阳下长期照射褪色的缺点，并且本产品使用氧化锌无机紫外线屏蔽剂，有效将紫外线折射出去，更好的保护产品膜的颜色。
具体实施方式
下面本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。
