Abstract

The invention belongs to the technical field of rubber materials and preparation of the rubber materials, and particularly relates to a blending type rubber compound and a preparation method thereof. The rubber compound comprises, by weight, 75-85 parts of ethylene-propylene-diene monomer (EPDM), 15-25 parts of rubber type chlorinated polyethylene (CPE), 2-3 parts of dicumyl peroxide (DCP), 0.8-1.5 parts of triallyl isocyanurate (TAIC), 25-35 parts of talcum powder, 25-35 parts of N660, 4-6 parts of TP759, 1-1.5 parts of SA and 3-6 parts of ZnO. The rubber type CPE and the EPDM are mixed in a certain proportion and other assistants are added simultaneously to obtain the blending type rubber compound through corresponding preparation processes, so that chlorine elements are added on the molecular weight of the EPDM, and the modified ethylene propylene rubber (EPR) not only reserves corrosion resistance of the EPR, but also is provided with good physical and mechanical properties and processability. The problems of the poor oil resistance and high cost of the existing EPR can be solved.

Description

technical field [0001] The invention belongs to the technical field of rubber materials and their preparation, and in particular relates to a blended rubber compound and a preparation method thereof. Background technique [0002] Currently used ethylene propylene rubber, the usual method is to soak EPDM rubber in No. 903 standard oil, and after 70 hours at 125 ° C, its volume swelling is about 70%, and the obtained product There are generally problems of poor oil resistance and high cost and price. Therefore, a kind of rubber compound and its preparation method that can solve the above problems are needed to meet the needs of the actual situation. Contents of the invention [0003] The invention provides a kind of blending type rubber compound and its preparation method. It blends rubbery chlorinated polyethylene and EPDM rubber according to a certain ratio, and adds some other auxiliary agents at the same time, and through corresponding According to the preparation proce...
