Enhanced the Property of PP/EPDM with CaCO₃

Abstract:

Polypropylene（PP）as the interchangeable plastic has some unique advantages and drawbacks. PP toughening by rubbery particles especially EPDM has been researched a lot. As the research progresses, more and more researchers recognize that the single rubbery particles could not solve the problem in PP. It becomes a trend and necessity that PP was toughening modified by using rigid particles. But the rigid particles could not combine with matrix resin. Before the application, it should modify rigid particles first. This article takes CaCO₃ as example modified by titanate coupling agent. Then, the modified CaCO₃ was identified by FT-IR and detected the activation degree. After that, using the modified CaCO₃ and unmodified CaCO₃ blending with PP/EPDM respectively and then compare the mechanical properties.
