Preparation and performances of ethylene-propylene-diene terpolymer/acrylic rubber reinforced with a dough-modeling compound
A novel composite was prepared by the addition of a dough-modeling compound (DMC) reinforcement and an ethylene-propylene-diene terpolymer (EPDM)/acrylic rubber (ACM) matrix. We studied the DMC/EPDM/ACM mass ratio and vulcanizing process by testing the tensile strength, Shore A hardness, elongation at break, and wear and thermal properties. The results show that the mechanical properties, thermal properties, and wear resistance of the composites were good when the DMC/EPDM/ACM mass ratio was 70/25/75 and the cure conditions were 180 degrees C under 10 MPa for 25 min. The crosslinking structure of the composites was studied by IR, and this further proved the interaction between DMC, ACM, and EPDM. (c) 2007 Wiley Periodicals, Inc.
