Problems solved by technology

[0003] There are many reasons for the above. One is the material of the wiper rubber strip. Commonly used wiper rubber strips cannot withstand high and low temperature, and cannot withstand aging; the second is that the surface of the automobile glass contains hydrophilic groups such as hydroxyl groups. There is a certain force between them, so that the raindrops cannot be completely scraped off

preparation example Construction

[0063] The preparation method of phenylmethyl silicone oil described in the present invention is as follows: add 100ml water and 40ml toluene in three-neck round-bottomed flask, slowly drop into 0.33mol (CH 2 ) 2 SiCl 2 , 0.038mol Ph 2 SiCl 2 and 0.010mol(CH 3 )SiOSi(CH 3 ) 3 Mixed solution, control system temperature below 50°C. After 5h, the reaction was stopped, and the toluene phase was separated and washed with water until neutral. Filter, remove toluene by rotary evaporation, and dry in vacuum at 80°C for 2 hours to obtain a colorless transparent liquid.

[0064] In one embodiment, the mole fraction of the phenyl group is 1-18%, preferably 7%-11%, more preferably 9%.

Abstract

The invention discloses a rubber composition. The rubber composition at least comprises the following components in parts by weight: 100 parts of a rubber basic material, 10-40 parts of a silicone oil composition, 10-60 parts of a filler, 1-5 parts of a cross-linking agent, 1-10 parts of a constitution controller, and 0.1-1.5 parts of a lubricating agent; the rubber basic material at least comprises silicone rubber; the silicon oil composition at least comprises methyl-phenyl silicon oil and alkyl silicon oil, and the weight ratio of the methyl-phenyl silicon oil to the alkyl silicon oil is 1:0.01-0.1; and the filler is a hyperbranched polysiloxane modified silicon dioxide nanosheet containing an epoxy group. The invention further discloses a treatment method of a surface of waterproof glass and a self-lubricating rubber sealing strip.

Description

technical field [0001] The invention relates to a rubber composition, in particular to the composition of the rubber composition, a treatment method for waterproof glass and a self-lubricating rubber sealing strip prepared by using the rubber composition. 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 use angle of the wiper rubber sealing strip and the material of the car glass, there is often the disadvantage that the raindrops cannot be completely scraped off. At the same time, the wiper rubber seal strips of automobiles are often placed in relatively harsh environments, such as under the sun in summer and rainy and snowy days in winter. In rainy and snowy weather, the colloid of the rubber sealing strip of the wiper tends to harden and cannot wipe the rain and snow smoothly; in the process of swinging, there will be "clucking" jumping scrapes and other situations. ...
