Problems solved by technology

However, some traditional tire repair aerosols can only temporarily inflate the deflated tires, and even cause chronic deflation after a period of time; some antifreeze effects are very poor, such as Chinese patent 92109046.3; Or the disadvantages of destroying the ozone layer have not been widely used

Abstract

The invention relates to an automatic inflation tyre-repairing solution. The solution comprises the following raw material components in parts by weight: 50-70 parts of natural latex, 3-10 parts of emulsifier, 10-20 parts of antifreezing agent, 3-5 parts of surfactant, 0.3-1 part of stabilizer, 10-20 parts of distilled water and 100 parts of propellant. The automatic inflation tyre-repairing solution uses natural concentrated latex as main raw material and also uses various main agents such as antifreezing agent, foaming agent, stabilizer and polymerization inhibitor; the product cost is low, the shelf life is long, the period of validity is up to 6 months, the freezing resistance is good so that the solution can be used at -20 DEG C; and the jet velocity is high, the tyre-repairing effect is good, the preparation method is simple and the economic and social benefits are remarkable.

Description

technical field [0001] The invention relates to a self-inflating and leak-trapping mixture for rubber tires and a preparation method thereof. Background technique [0002] Most of the tires used at this stage are pneumatic tires. After being punctured by nails or hard objects on the road surface, it will cause acute deflation. The traditional tire sealant needs to go through a series of processes such as unloading the wheel, removing the tire, and repairing the tire. The procedures are complicated, laborious and time-consuming. Especially when driving in the wild, there is no condition for tire repair. After the tire is punctured, it is impossible to continue driving. [0003] In order to solve the above problems, some people have invented tire repair glue, most of which adopt polyvinyl acetate emulsion or polyvinyl alcohol solution, together with starch, cellulose and inorganic fillers, etc., the sealing composition is relatively simple, fluidity, stability, oxidation resis...
