The material is characterized in that the following components are proportionally mixed in parts by mass: 70-90 parts of EPDM (ethylene propylene diene monomer); 2-4 parts of zinc oxide; 1-3 parts of stearic acid SA; 2.5-4 parts of antiager BLE (liquid); 2-3.5 parts antiager SP (liquid) of 0.5-2 parts of antiager RD; 55-65 parts of N550 carbon black; 18-21 parts of EPM (binary ethylene propylene copolymer); 19-22 parts of StronWiNTC; 19-21 parts of liquid EPDM; 0.5-1.5 parts of assistant crosslinker IS; 1-2 parts of accelerant DM; 0.5-1.5 parts of crosslinker 96% peroxide vulcanizing agent DCP; 1.5-2.5 parts of polyethylene glycol; the invention further discloses a manufacturing process of the rubber material; the rubber material disclosed by the invention is high in quality and low in cost, does not expand in brake liquid, softener is not extracted, and volume expansion, solution, contraction and other phenomena of master and assistant cups are not caused.

Description

technical field [0001] The invention relates to an EPDM / EPM anti-motorcycle synthetic brake fluid expansion rubber material, and also relates to a manufacturing process of the rubber material. Background technique [0002] Automobile brake fluid, also known as brake oil or brake fluid, is composed of base oil or base fluid and various additives. It is a functional liquid used to transmit pressure in the hydraulic braking system of automobiles and make the wheel brakes achieve the braking effect. . There are three types of brake fluid, ① castor oil-alcohol type, ② synthetic type: made of ether, ester, etc. mixed with lubricant, alcohol, anti-oxidation, anti-rust, anti-rubber swelling and other additives, ③ mineral oil type: refined It is made by adding thickener and other additives by fractional distillation of light diesel oil, and the working temperature range is -70°C to 150°C. Its performance is good, but the brake system must be equipped with rubber parts resistant to ...
