The present invention discloses a rubber composition, a processing method thereof, and also a brake fluid-resistant product using the rubber composition and a production method thereof. The rubber composition comprises, in parts by weight, 100 parts of a rubber matrix; 1.5-8 parts of a crosslinking agent 40-140 parts of a reinforcing filler; and 0-40 parts of a plasticizer, wherein the rubber matrix comprises, based on 100 parts by weight of the rubber matrix, a branched polyethylene with a content represented as A, in which 0<A≤100 parts; an EPM with a content represented as B, in which 0≤B<100 parts; and an EPDM with a content represented as C, in which 0≤C<100 parts. The rubber composition is useful in the production of brake fluid-resistant brake rubber hose and brake rubber diaphragm. The beneficial effect is that since the rubber composition comprises the branched polyethylene, the tear strength of the rubber compound is improved, thereby reducing the probability of tearing of the product during the production process and improving the overall processing performance. |
