Abstract

The invention discloses a sealing rubber strip for an automobile window. The sealing rubber strip is made of the following materials in parts by weight: 22-26 parts of polyvinyl chloride, 40-45 parts of ethylene-propylene-diene-terpolymer rubber, 6-10 parts of paraffin, 7-11 parts of poly propadiene siloxane, 12-15 parts of tert-Butylhydroquinone, 18-20 parts of diisobutyl phthalate, 9-14 parts of sulfydryl acid ester, 8-12 parts of lauryl alcohol polyoxyethylene, 6-12 parts of sodium fluosilicate, 2-4 parts of coal gangue, 15-20 parts of carbon black, 2-3 parts of trichlorofluoromethane, 4-8 parts of sodium alcohol ether sulfate, 6-11 parts of aluminum borate crystal whisker, 12-14 parts of silicic acid hydrate, 9-15 parts of sodium antimonate, 3-8 parts of diisopropylamine and 7-11 parts of glyceryl tristearate. The sealing rubber strip of the automobile window is provided with bubbles inside and is good in elasticity, good in corrosion resistance and aging resistance, and long in service life.

Description

technical field [0001] The invention relates to a sealing strip for automobile windows and a preparation method thereof. Background technique [0002] The sealing strip is a product that seals something so that it is not easy to open, and has the functions of shock absorption, waterproof, sound insulation, heat insulation, dustproof, and fixing. The sealing strips are made of rubber, paper, metal, and plastic. , A variety of materials. It can be divided into solid products (round, square, flat cross-sectional shape), hollow products and metal rubber composite products. Among them, metal-rubber composite sealing strips account for more than 60%. Sectional design is very important for rubber sealing strips. The first is the shape and size design of the sealing lip. The sealing lips on both sides should contact the glass from both sides of the window glass with the same and appropriate force. The length and thickness of the lip should be appropriate. If it is too thick or t...
