技术领域
本发明涉及灯具塑料、灯饰塑料，具体公开了一种金属效果的免喷漆灯具塑料及其制备方法。
背景技术
目前的灯具、灯饰采用的金属效果塑料外壳，普遍采用在塑料上喷金属漆以达到模仿金属视觉效果的目的，然而塑料或者金属之间进行喷漆前，必须进行表面防刮处理或进行单独包装保护，喷漆过程中需要使用有机溶剂稀释油漆，喷涂完成后需要等待干燥，喷涂之后又需要进行防刮保护，导致灯罩、灯饰的上色工艺复杂、有机溶剂毒性大、污染严重、加工成本高、耗费工时长。并且喷漆工艺的产品很难通过ROHS认证以及VOCS测试，喷漆产品很难回收再利用。
发明内容
为了克服现有的灯具、灯饰采用的金属效果塑料外壳采用喷漆工艺而导致的污染大、成本高、无法回收利用的问题，本发明提供一种金属效果的免喷漆灯具塑料及其制备方法。
