Abstract

The invention discloses ethylene propylene diene monomer rubber for an automobile brake hose and a preparation method thereof. The rubber comprises the following components in parts by weight: 100 parts of ethylene propylene diene monomer rubber EP350, 0.5-1.8 parts of sulfur S, 0.5-2.0 parts of vulcanizing agent DCP, 0.6-1.8 parts of accelerator DM, 0.5-1.5 parts of accelerator TT, 1.2-1.5 parts of accelerator PX, 5.0-8.0 parts of ZnO, 10.0-40.0 parts of carbon black N550, 10.0-40.0 parts of carbon black N330, 5.0-20.0 parts of pottery clay, 3.0-5.0 parts of white carbon black, 1.0-3.0 parts of coupling agent Si-69, 5.0-9.0 parts of rubber adhesive XS-100, 1.5-2.0 parts of stearic acid StA, 5.0-8.0 parts of aromatic oil, 1.0-2.0 parts of microcrystalline wax, 1.0-2.0 parts of anti-aging agent A, and 1.0-2.0 parts of anti-aging agent RD. Internal mixing, open milling, sheet lowering and vulcanization of a rubber sheet are performed on raw materials to obtain a rubber compound of the ethylene propylene diene monomer rubber. The ethylene propylene diene monomer rubber disclosed by the invention can improve the anti-aging performance and the blast resistance of the automobile brake hose, greatly upgrade the anti-ozone aging performance, the anti-thermal oxidative aging performance and the binding strength and effectively prolong the service life of the brake hose.

Description

technical field [0001] The invention relates to the preparation of EPDM rubber, specifically refers to a kind of automobile brake rubber which is used to manufacture rubber products such as automobile brake hoses, which is resistant to ozone aging, heat and oxygen aging, and has strong bonding force with skeleton materials. EPDM rubber for hose and its preparation method. Background technique [0002] Automobile brake hoses are used under harsh conditions, and their service life is one of the main factors affecting the safety performance of automobiles. Automobile brake hoses are corroded by heat, ozone, and rain, as well as the impact of instantaneous pressure increase during braking, which can easily lead to cracks and explosions in the rubber layer, reducing the safety factor of the vehicle. In short, the poor aging resistance and blast resistance of automobile brake hoses are the reasons for this phenomenon. Contents of the invention [0003] Aiming at the deficienci...
