Abstract

The invention discloses a rubber material. The rubber material is composed of the following raw material in parts according to the formula: 100-150 parts of ethylene-propylene-diene-terpolymer rubber, 20-30 parts of organic silicon resin, 15-25 parts of silicone oil, 10-15 parts of a cross-linking agent, 15-25 parts of a polytetrafluoroethylene lubricant additive, 10-20 parts of diatomite powder, 10-15 parts of feldspar powder, 5-10 parts of dicumyl peroxide, 5-15 parts of 1,2-propylene glycol, 10-15 parts of a defoaming agent and 30-35 parts of epoxy resin. The rubber material has excellent self-lubricant performance and is convenient to prepare, and when applied to the windscreen wiper, the rubber material has good cleaning effect on glass, is capable of slowing down the rubber aging of a windscreen wiper and generates extremely small friction force on the surface of a windscreen.

Description

technical field [0001] The invention relates to the technical field of rubber materials, in particular to an organic rubber material containing self-lubricating additives, which can be used in automotive windshield wipers and the like. Background technique [0002] With the improvement of people's daily life standards, the automobile industry has also developed rapidly, and more and more existing automobiles have entered people's ordinary lives, and many automobile industries today are also generally closely related to people's lives. With the continuous development of automobiles, the products used in automobiles are constantly being updated and improved. The wipers on the windshield of the car can clean the windshield and improve the driving sight in rain, snow and other weather. The traditional wiper is made of natural rubber material, which is easy to age due to the poor weather resistance of natural rubber material. As a result, the wiper cannot remove rainwater and cl...
