The invention provides a PMMA (polymethyl methacrylate) composition for a vehicle lamp material. The PMMA composition comprises the following main components: 91.5-99.2 parts of a polymethyl methacrylate base material, 0.2-4 parts of black toner, 0.1-0.5 part of a lubricant, 0.1-1 part of a main antioxidant, 0.1-0.5 part of an auxiliary antioxidant, 0.2-2 parts of a light stabilizer and 0.1-0.5 part of a heat-resistant agent. The material can be widely applied to preparation of black skirt materials for vehicle lamps, can adapt to various welding operations below 450 DEG C, and is free of abnormal phenomena such as fusion, wiredrawing and adhesion.

    本发明提供了一种用于车辆灯具材料的PMMA组合物,主要成分包括:聚甲基丙烯酸甲酯基材91.5~99.2份,黑色色粉0.2~4份,润滑剂0.1~0.5份,主抗氧剂0.1~1份,辅助抗氧剂0.1~0.5份,光稳定剂0.2~2份,耐热剂0.1~0.5份。本材料能够广泛适用于制备车辆灯具黑色裙边材料,能够适应450℃以下各种焊接操作,且材料无熔融、拉丝、黏连等异常现象。
