Using carbon black,white carbon black and lightweight calcium carbonate as reinforcing fillers,butyl rubber/polypropylene(IIR/PP)type thermoplastic vulcanizate(TPV)materials reinforced with different fillers were prepared by dynamic vulcanization method.The research showed that the compatibility between different fillers and matrix materials was all good,and the heat resistance performance of TPV materials reinforced with different fillers did not differ much.TPV reinforced with lightweight calcium carbonate filler had relatively high hardness and tensile strength,lower compression permanent deformation value,but its thermal oxidative aging performance was relatively poor.The thermal oxidative aging performance of TPV materials reinforced with carbon black and white carbon black fillers maintained relatively better.
