一种易于油漆附着的改性PP/EPDM材料及其制备方法和应用
摘要：
本发明涉及工程塑料改性技术领域，特别是一种易于油漆附着的改性PP/EPDM材料及其制备方法和应用。改性后的PP/EPDM/M15带有-【-RG1-NH-COO-R1-COOR2G2-】m-高分子链，其表面带有活性羰基、氢及部分羟基基团，表面极性增大，使油漆较容易附着。改性材料应用于注塑所得的汽车轮毂罩盖或下沿饰板或防擦条或发动机罩盖。
摘要（英）：

The invention relates to the technical field of engineering plastics modification, particularly discloses modified PP/EPDM materials easy to be attached by paint, a preparation method thereof and application. PP/EPDM/M15 after being modified carries a -(-RG1-NH-COO-R1-COOR2G2-) m- polymer chain, and the surface of the PP/EPDM/M15 carries carbonyl, hydrogen and part of hydroxyl group, therefore, the surface polarity is increased, and the paint is easy to attach to the surface. The modified materials are applied to a vehicle hub shroud or a lower edge decorative plate or an anti-friction bar oran engine hood which is obtained by injection molding.
