Abstract

The invention discloses a high temperature resistance odorless peroxide rubber composition and a preparation method thereof. The peroxide rubber composition comprises the following components in part by weight: 100 parts of rubber, 5 parts of zinc oxide, 1 part of stearic acid, 4 parts of anti-aging agent, 5 parts of plasticizer, 2 to 5 parts of vulcanizing agent DCP (Dibasic Calcium Phosphate), 0.3 to 0.5 part of sulphur, 1.8 parts of cross-linking agent and 0.1 to 0.5 part of methyl ionone. The preparation method comprises the following steps of: starting an open mill or an internal mixer, firstly adding the rubber, then adding the zinc oxide, stearic acid and the anti-aging agent to refine, adding carbon black and the plasticizer to refine and carrying out discharging and standing; after softening the obtained sizing material, adding the vulcanizing agent DCP, the cross-linking agent and the sulphur into the sizing material to refine, carrying out discharging and standing, then adding the methyl ionone to refine and carrying out methyl discharging and standing; and finally, carrying out vulcanization. The high temperature resistance odorless peroxide rubber composition has simple formula, excellent heat resistance and low price and is easy to operate; the problem of odor generated in the vulcanizing process of the vulcanizing agent is solved; and the high temperature resistance odorless peroxide rubber composition is odorless, even is slightly fragrant.

Description

technical field [0001] The invention relates to a high-temperature-resistant odorless peroxide rubber composition, which belongs to the technical field of rubber compositions. Background technique [0002] In the use of rubber, general materials require rubber with good heat resistance. Usually, EPDM rubber and nitrile rubber are selected for formula design. Usually, sulfur vulcanization system (S) and peroxide are selected for the vulcanization system. Vulcanization system (DCP), has been proved by various experiments that under the comparison of heat aging and high temperature resistance, peroxide vulcanization system (DCP) is better than sulfur vulcanization system (S) in high temperature resistance, not easy to aging, low compression deformation, no vulcanization reversion The advantages of originality, no blooming phenomenon, and simple formula design are preferred. [0003] During the use of the peroxide curing system (DCP), some weaknesses or shortcomings have also a...
