Problems solved by technology

However, when a car tire blows out and there are no auto repair shops around, changing a tire is a hassle and laborious task
At present, there are many self-inflating tire sealants on the market, but organic solvents are common, some contain freon gas that has been banned for a long time, some are highly corrosive to the wheel hub, and the adhesive components in many tire sealants have a strong bond Low, weak adhesion to the tread, generally poor durability after repairing the tire, and slow air leakage occurs within a few hours
In short, many tire repair nights currently on the market are generally not environmentally friendly, have the disadvantages of corroding the hub, weak adhesion, and poor durability.

Embodiment 1

[0024] A kind of environment-friendly high-efficiency self-inflating tire sealant liquid, comprises the raw material of following mass percentage content:

[0025]

[0026] The specific implementation steps of this environment-friendly and efficient automatic inflation tire sealant are:

[0027] The above raw materials are configured according to the mass percentage, stirred evenly, packed into a can and covered, and filled with nitrogen. Example 2:

Embodiment 2

[0028] A kind of environment-friendly high-efficiency self-inflating tire sealant liquid, comprises the raw material of following mass percentage content:

[0029]

[0030]

[0031] The preparation method is the same as in Example 1.

Embodiment 3

[0033] A kind of environment-friendly high-efficiency self-inflating tire sealant liquid, comprises the raw material of following mass percentage content:

[0034]

[0035] Preparation method is the same as example 1.

[0036] Based on Example 1, all parameters and steps are consistent with those in Example 1, change the addition of "modified water-based polyurethane-epoxy resin emulsion", rubber powder, sawdust powder, and measure the durability of the tire sealant . The specific parameters are shown in the table below:

[0037] Table 1 The impact of the main component addition amount on the durability of the tire sealant

[0038]

[0039]

[0040] As can be seen from the above table, in terms of mass percentage, only when the addition amount of "modified water-based polyurethane-epoxy resin emulsion" is 30-40%, the addition amount of rubber powder is 8%-10%, and the addition amount of sawdust powder When the addition amount is 1-2%, the performance of the tire se...

Abstract

The invention belongs to the technical field of preparation of chemical adhesives, and in particular relates to an environment-friendly efficient automatic-inflation tire repair fluid and a preparation method thereof. The environment-friendly efficient automatic-inflation tire repair fluid comprises the following raw materials in percentage by mass: 30-40% of modified waterborne polyurethane-epoxy resin emulsion, 8-10% of rubber powder, 1-2% of sawdust powder, 1-3% of ethylene glycol, 2-5% of polyvinyl alcohol, 0.5-1% of OP-10, 0.5-1% of lauryl sodium sulfate, 8-10% of water, and 28-49% of compressed nitrogen gas, based on 100% in total. The automatic-inflation tire repair fluid is green and environmentally-friendly, takes water-based materials as raw materials, and does not contain an organic solvent; moreover, the raw materials do not contain ammonia gas and do not contain a corrosive solvent, so that the emulsion is neutral, and hubs are not corroded; nitrogen gas which is safe, does not burn and does not explode is adopted, and the atmosphere is not polluted due to the fact that Freon is not contained; and the high-cohesiveness modified waterborne polyurethane-epoxy resin emulsion is used as a film-forming substance, so that the use time of the tire is greatly prolonged.

Description

technical field [0001] The invention belongs to the technical field of preparation of chemical adhesives, in particular to an environment-friendly, high-efficiency self-inflating tire repair liquid and a preparation method thereof. Background technique [0002] At present, with the rapid economic development, my country's car ownership has exceeded 100 million. [0003] Cars have greatly facilitated people's lives. However, when a car tire blows out and there is no car repair shop around, it is a very troublesome and laborious thing to change the tire. At present, there are many self-inflating tire sealants on the market, but organic solvents are common, some contain freon gas that has been banned for a long time, some are highly corrosive to the wheel hub, and the adhesive components in many tire sealants have bond strength Low, and the adhesion to the tread is weak. After the tire is repaired, the durability is generally not good, and the phenomenon of slow air leakage w...
