The invention provides a colored micro-foaming TPV (thermoplastic vulcanizate) material as well as a preparation method and application thereof. The colored micro-foaming TPV material comprises PP, EPDM, POE, paraffin oil, kaolin, a cross-linking agent, a cross-linking auxiliary agent, a micro-foaming agent, an antioxidant, an ultraviolet light absorber, a processing auxiliary agent and color master batch. The method can be applied to production of automobile sealing strips, such as water cutting sealing strips and the like. The requirement for color diversification of automobile exterior trimming parts is met, meanwhile, due to mature application of the micro-foaming technology, the outer surface of a produced sealing strip product is smooth, the material use amount is reduced by about 20%, and the requirement for light weight of automobiles is met.
本发明提供了一种彩色微发泡TPV材料及其制备方法和应用。该彩色微发泡TPV材料包含PP、EPDM、POE、石蜡油、高岭土、交联剂、交联助剂、微发泡剂、抗氧剂、紫外线吸收剂、加工助剂、色母。它可应用于汽车密封条,如水切密封条等的生产。本发明满足了汽车外饰件颜色多样化的要求,同时微发泡技术的成熟应用,生产的密封条产品外表面光滑,降低材料使用量20%左右,符合汽车轻量化的要求。
