NANO ZINC OXIDE FILLED WEATHER STRIP RUBBER COMPOSITION AND WEATHER STRIP FOR CAR USING THE SAME

摘要

The present invention relates to a weather strip rubber composition for automobiles. More particularly, the present invention relates to an ethylene propylene diene rubber (EPDM) which is a raw material of a basic rubber to enhance abrasion resistance and mechanical properties Carbon black for heat resistance, and nano zinc oxide for improving heat resistance, other rubber softening agents, crosslinking agents, crosslinking accelerators, antioxidants and ozone antioxidants at optimal ratios and adding nano zinc oxide as a crosslinking activator to improve heat resistance, Permanent deformation and the like, thereby contributing to an improvement in the efficiency of wind noise leaking into a door gap of a vehicle during traveling.;
