| The functionality of modified plastics in today's plastic industry is a major trend. In this paper, inorganic and organic materials were filled into PP to prepare matt masterbatch, and discussed the optical and mechanical properties of the masterbatch after processing into films. Also used solid method to prepare PP grafted MAH, and researched inorganic composite particles enhance the toughness of modified polypropylene. PP with excellent ductility mixing matt agent was studied to prepare matt masterbatch. After a series of optical test, compared was on different dosage matt agent of the entire system. And under differential scanning calorimeter (DSC), the crystallization behaviors of the material were investigated.Discussed optical properties of several matt films and their tensile strength and bi-directional elongations at break in order to make some comparisons, the surface of masterbatch material was observed by scanning electron microscopy.The macro-mechanical property of polymer is strongly influenced by its crystallization behavior. And for crystalline polymer blend, because of the existence of the second component, the chemical and physical environment changed when the crystalline components in the melt mode.Differential scanning calorimeter (DSC) on the crystallization of the material were investigated. And the performance of whole optical system was analysed in accordance with the crystallization kinetic parameters.Because PP is the non-polar polymer, so when the inorganic particles were filled in the PP, the system can not be in a very good dispersion, this paper discussed that solid method was used to prepare PP grafted MAH to improve the compatibility of the agent when added to PP/inorganic nanocomposites material. The performance of different PP-g-MAH grafting methods impacts the whole nano-CaCO3 and PP matrix system. Through the test of the mechanical properties, and analysis of IR and SEM, we observed the changes of PP/PP-g-MAH/ nano-CaCO3 composite material in the structure and properties. |
