Problems solved by technology

Since the brake pipe is filled with DOT brake fluid for a long time, the inner material of the rubber pipe is easy to be extracted and crystallized or deposited in the brake pipe, and the temperature rise caused by the engine compartment will cause the rubber pipe to age in advance and lose the use effect. The ability of the tube to withstand DOT at high temperature determines the overall safety of the car

Abstract

The invention relates to a rubber material for braking, which is prepared from the following raw materials in parts by weight: 6-10 parts of dioctyl ester, 3-9 parts of titanium white, 8-14 parts of ethylene propylene diene monomer rubber, 3-5 parts of microcrystalline wax, 4-9 parts of hindered phenol antioxidant, 4-7 parts of trichloropropylphosphate, 4-6 parts of peroxide vulcanizing agent, 3-7 parts of hypalon, 6-8 parts of hydrogenated nitrile-butadiene rubber, 2-8 parts of semi-reinforcing carbon black, 3-9 parts of cyclohexylthio phthalimide and 1-5 parts of stearic acid. The rubber material for braking has the advantages of excellent high temperature resistance, friction resistance and low deformation tendency.

Description

technical field [0001] The invention relates to a rubber material for braking. Background technique [0002] Automobile brake hose (commonly known as brake pipe) is a component used in the automobile braking system. Its main function is to transfer the brake medium in the automobile brake to ensure that the braking force is transmitted to the automobile brake shoe or brake caliper. Generate braking force so that braking is effective at any time. The rubber brake hose has the advantages of strong tensile strength and easy installation, but the disadvantage is that it is easy to age on the surface after long-term use. The brake pipe plays the role of conveying brake fluid and transmitting brake pressure in the automobile brake system. Since the brake pipe is filled with DOT brake fluid for a long time, the inner material of the rubber pipe is easy to be extracted and crystallized or deposited in the brake pipe, and the temperature rise caused by the engine compartment will c...
