Abstract

The invention discloses an anti-tear anti-deformation silicone rubber material for a windscreen wiper. The material is prepared from, by weight, 75-85 parts of methyl silicone rubber, 45-55 parts of polyglycolic acid, 5-10 parts of disulphide diisopropyl xanthate, 10-14 parts of epichlorohydrin rubber, 5-8 parts of graphite, 3-8 parts of aluminum hydroxide, 2-8 parts of palmitic acid, 2-5 parts of dibutyl tin diacetate, 5-8 parts of dibutyltin dilaurate, 10-15 parts of white carbon black, 8-15 parts of calcium stearate, 3-5 parts of stannous octoate, 5-10 parts of sodium carboxymethylcellulose, 35-55 parts of water and 2-8 parts of hexynol. The anti-tear anti-deformation silicone rubber material for the windscreen wiper is excellent in anti-tear property, small in compressive deformation, low in production cost and high in economic benefits.

Description

technical field [0001] The invention belongs to the field of polymer materials, and in particular relates to a tear-resistant and deformation-resistant silicon rubber material for wipers. Background technique [0002] When the vehicle is driving in rainy days, it is necessary to continuously use the wiper to ensure clear vision. Due to the angle of use of the wiper and the material of the car glass, there is often the disadvantage that raindrops cannot be completely wiped off. At the same time, the windshield wipers of automobiles are often placed in relatively harsh environments, such as under the sun exposure in summer and rainy and snowy days in winter. In rainy and snowy weather, the gel of the wiper tends to harden and cannot wipe rain and snow smoothly; in the process of swinging, there will be "clucking" jumping scrapes and other situations. Moreover, when the car is running, the dust on the glass surface of the car needs to be wiped off additionally. The above-men...
