Problems solved by technology

[0004] Ammonia is one of the components of tire sealant, and it is used as a latex stabilizer and pH regulator. However, in traditional car tire sealant, the ammonia content is too high, which leads to poor user experience and obvious odor; at the same time, high ammonia content is also Make the pH of the system alkaline, highly corrosive, and easily cause certain corrosion to the car hub

preparation example Construction

[0022] The preparation method of the low-ammonia automobile tire sealant in the present invention is as follows.

[0023] A. Weigh 10-28 parts by weight of water and 31-36 parts by weight of antifreeze, put them in a water bath, and stir at 80°C-90°C.

[0024] B. Weigh 0.5-1 part by weight of polyacrylamide, add it into the water bath in step A with stirring, and stir at 60°C-75°C for 20-40 minutes. The molecular weight of polyacrylamide is 4 million-6 million.

[0025] C. Weigh 0.5-1 parts by weight of sodium polyacrylate, add it into the water bath in step B under stirring, and stir for 20-40 minutes at 65°C-80°C. The molecular weight of sodium polyacrylate is 70 million-90 million. Set to obtain the mixture a.

[0026] D. Add 0.05-0.25 parts by weight of phosphoric acid to 35-50 parts by weight of ammonia-free natural rubber latex and stir for 20-50 minutes. After standing for 40-50 hours, take the latex that is more than three-quarters of the depth of the stirring pot...

Embodiment 1

[0034] Example 1: 35 parts of ammonia-free natural latex; 3 parts of rosin modified emulsified dispersion; 22 parts of ethylene glycol; 10 parts of glycerol; 0.8 parts of thickener; 0.7 parts of polyacrylamide; 0.3 part of sulfosuccinic acid alkylphenol polyoxyethylene ether; 0.25 part of fatty alcohol polyoxyethylene ether; 0.07 part of bactericide; 28 parts of water; wherein, the molecular weight of the polyacrylamide is 400W-800W, polyacrylic acid The molecular weight of sodium is 7000W-9000W.

Abstract

The invention discloses low-ammonia automobile tire repair liquid. The low-ammonia automobile tire repair liquid comprises the following components according to the parts by weight: 35-50 parts of ammonia-free natural latex, 1-6 parts of rosin-modified emulsified dispersion liquid, 31-36 parts of an antifreezing agent, 0.5-1 part of a thickener, 0.5-1 part of polyacrylamide, 0.01-0.1 parts of ammonia water, 0.05-0.25 parts of phosphoric acid, 0.1-0.5 parts of sulfosuccinate alkylphenol polyoxyethylene ether, 0.1-0.5 parts of fatty alcohol-polyoxyethylene ether, 0.02-0.08 parts of a bactericide, and 10-28 parts of water, wherein a molecular weight of the polyacrylamide is 400-800 W. The invention further provides a preparation method for the low-ammonia automobile tire repair liquid. In a formula of the low-ammonia automobile tire repair liquid, through a rational ratio, a proportion of the ammonia water is reduced while the repair effect is guaranteed, so the using experience of a customer is improved, the alkalinity of a system is reduced, and the corrosive effect to an automobile hub is reduced too. The low-ammonia automobile tire repair liquid has no heavy metal components, andis environment-friendly and good in stability.

Description

technical field [0001] The invention belongs to the field of automobile tire sealant, and in particular relates to a low-ammonia automobile tire sealant, and also relates to a preparation method of the low-ammonia automobile tire sealant. Background technique [0002] With the development of the economy and the improvement of people's income, there are more and more vehicles driving on the road. During the driving process of the car, sharp objects will puncture the tires when encountering bad road conditions, and tire repair operations are required. Conventional tire repair operations need to be carried out at professional auto repair shops, which takes a long time. If the owner himself Carrying out routine tire repair and tire replacement operations is not everyone's skill because tires are bulky, highly professional, and troublesome. Therefore, now with the emergence of tire protective agent (automatic tire sealant), the operation of tire repair has been greatly simplifie...
