Embodiment 1

[0038] The specific raw materials are weighed according to Table 1, and the preparation steps are as follows:

[0039] (1) water and ethylene glycol half of the formula amount are placed in the reaction vessel, and stirred at 80°C for 20min;

[0040] (2) magnesium sulfate was added to the reaction vessel, and stirred at 75°C for 30min;

[0041] (3) add alkylphenol polyoxyethylene ether and sodium hydroxide successively to the reaction vessel, stop heating after dissolving, and cool to 35 ℃-45 ℃ while stirring;

[0042] (4) adding the remaining water, silicon dioxide and polyvinyl alcohol of the formula in turn, and continuing to stir for 10min at 35°C-45°C;

[0043] (5) Add natural latex and modified styrene-butadiene rubber in turn, continue to stir for 30min, stop stirring, and that is obtained.

Embodiment 2

[0045] (1) water and ethylene glycol half of the formula amount are placed in a reaction vessel, and stirred at 90°C for 10min;

[0046] (2) magnesium sulfate was added to the reaction vessel, and stirred at 60°C for 40min;

[0047] (3) add alkylphenol polyoxyethylene ether and sodium hydroxide successively to the reaction vessel, stop heating after dissolving, and cool to 35 ℃-45 ℃ while stirring;

[0048] (4) adding the remaining water, silicon dioxide and polyvinyl alcohol of the formula in turn, and continuing to stir at 35°C-45°C for 20min;

[0049] (5) Add natural latex and modified styrene-butadiene rubber in turn, continue to stir for 20 min, stop stirring, and that is obtained.

Embodiment 3

[0051] The consumption is shown in Table 1, and the preparation method is the same as that in Example 1.

Abstract

The invention provides a composition with automatic tire repair function, which is composed of natural latex, modified styrene-butadiene rubber, polyvinyl alcohol, sulfate, alkylphenol polyoxyethylene ether, silicon dioxide, ethylene glycol Alcohol, sodium hydroxide, water. The invention has superior repairing function, is suitable for tires with various damaged areas, and effectively repairs damaged parts. The heat-resistant stability and cold-resistant stability of the invention are better than those of commercial products. The invention has stable properties, and can still maintain the original repair performance even if it is stored for a long time.

Description

technical field [0001] The invention relates to the field of auto parts, in particular to a composition with automatic tire repair function and a preparation method thereof. Background technique [0002] With the development of the economy and the improvement of people's income, more and more families begin to buy cars. car is driving [0003] During the process, when encountering roads with poor road conditions, sharp objects will puncture the tires, and tire repair operations need to be performed. Conventional tire repair operations need to go to a professional auto repair shop, which takes a long time. Now with automatic tire repairs The appearance of fluid greatly simplifies the tire repair operation. [0004] Tire repair fluid is a mixture containing a variety of polymer chemical materials. It is widely used in rubber tires of various electric vehicles, motorcycles and small and medium-sized automobiles. It has a better effect on tire punctures with small diameters. ...
