Abstract

The invention provides a tire puncture-proof, explosion-proof and leakage-proof internal adhesive and a preparation method thereof, and the internal adhesive is specifically prepared from the following components in parts by weight: 20-25 parts of chloroprene rubber, 15-20 parts of carbon black, 30-50 parts of asphalt, 7-10.5 parts of polyvinyl acetate, 3-7 parts of toluene diisocynate, 35-50 parts of sodium bicarbonate, 3-7 parts of toluene diisocynate, 10-15 parts of octanol, 30-45 parts of isopropanol, 10-25 parts of allyl methacrylate, 350-760 parts of water, 40-50 parts of an emulsifier and 510 parts of an initiator. The preparation method comprises the following steps: respectively preparing a solution A, a solution B, a solution C and a solution D, finally, mixing the solution A and the solution D according to a ratio of 17:1, conducting heating to 95-110 DEG C, and stirring the mixture for 30 minutes.

Description

technical field [0001] The invention relates to the technical field of tire glue, in particular to an anti-puncture, explosion-proof and leak-proof internal adhesive for tires and a preparation method thereof. Background technique [0002] As of September 2020, the number of motor vehicles in the country has reached 365 million, of which 275 million are cars. During the driving process of cars, tires are affected by factors such as road conditions, punctures by sharp objects, and the quality of the tires themselves. Air leakage is a common phenomenon in the daily driving of automobiles, and the air-leaking tires can still be used normally after proper treatment. [0003] Among the many tire repair methods in the industry, the room temperature vulcanization repair method is favored by repair personnel and drivers because of its simple operation, low price, and small damage to the tread, and has a good market prospect. [0004] The normal temperature vulcanization tire sealan...
