Problems solved by technology

At present, there are many types of tire sealants made in China, which are also very effective for the repair of normal temperature and small leaks, but there are still many defects, which mainly include: (1) corroding the rim, making the rim rust, which has side effects on the tire, making the tire Hardening and deformation, premature aging, affecting the service life of the tire; (2) the repaired crack is small, only small cracks can be repaired, and large holes cannot be repaired; (3) the inner tube cannot be repaired; (4) the antifreeze ability is limited, and the Use will cause gel and freeze, which cannot be restored after freezing, or the tire sealant will fail due to new chemical reactions when the tire temperature is too high

preparation example Construction

[0026] The preparation method of above-mentioned puncture sealant comprises the following steps:

[0027] 1) Add polyvinyl alcohol to deionized water that accounts for 40-80% of the mass of the deionized water raw material, stir at a temperature of 80-95°C for 2-5 hours, add bamboo powder and stir for 10-30 minutes, cool to normal temperature, and obtain solution one;

[0028] 2) Add methyl cellulose to the remaining deionized water of the raw material, stir at 50-80°C for 1-2 hours, add nano-inorganic filler, stir for 10-30 minutes, and then cool to room temperature to obtain solution 2;

[0029] 3) Mix solution 1 and solution 2 evenly, add alcohol antifreeze and stir at room temperature for 10-30 minutes, then add turpentine, triethylamine, azobisisobutyronitrile, sodium persulfate, rubber particles, nitrous acid Sodium and plaster of paris continue to stir for 10 to 30 minutes; add natural rubber latex and stir at room temperature for 0.5 to 1 hour.

Embodiment 1

[0032] A puncture sealant, characterized in that, based on the mass percentage of raw material components, the puncture sealant consists of the following components: 35% deionized water, 1% polyvinyl alcohol, 0.5% methyl cellulose, 1.3% turpentine %, triethylamine 0.52%, azobisisobutyronitrile 0.52%, sodium persulfate 0.52%, bamboo powder 2%, nano calcium carbonate 0.5%, glycerin 50%, rubber particles 1%, plaster 1% , sodium nitrite 0.5% and natural latex 5%.

[0033] The natural latex is high ammonia natural latex with 60% dry rubber content purchased from Thailand's Three Trees Company.

[0034] Preparation method: In terms of parts by mass, add 1 part of polyvinyl alcohol with a polymerization degree of 1700 to 25 parts of deionized water, stir at 80°C for 5 hours to completely dissolve it, and add 2 parts of bamboo with a particle size of 0.1mm Add the powder into the homogeneously dissolved solution, stir for another 30 minutes, then cool the solution to room temperature...

Abstract

The invention discloses a tire repairing agent and a preparation method thereof. The tire repairing agent consists of the following raw materials: deionized water, polyvinyl alcohol, methylcellulose,turpentine oil, triethylamine, azodiisobutyronitrile, sodium hydrogen persulfate, bamboo powder, nano-calcium carbonate, an alcohols antifreezing agent, rubber granules, calcined gypsum, sodium nitrite and natural latex. The grain size of the bamboo powder is 0.1-2 mm; the grain size of the rubber granules is 0.1-2 mm; the polymerization degree of the polyvinyl alcohol is 1,500-2,500; and the massratio of the turpentine oil, the triethylamine, the azodiisobutyronitrile and the sodium hydrogen persulfate is (0.5-3): (0.1-1): (0.1-1): (0.1-1), and the tire repairing agent is prepared by the steps of mixing of multiple layers of raw materials, stirring and the like. Compared with the prior art, the product has the characteristic that the airtightness and injection performance are further improved.

Description

【Technical field】 [0001] The invention belongs to the technical field of puncture repair, and in particular relates to a puncture repair agent and a preparation method thereof. 【Background technique】 [0002] With the development of society, the use of vacuum tires on motorcycles and automobiles has become increasingly widespread in recent years. Vacuum tires have high elasticity and wear resistance, good adhesion and heat dissipation performance, and their safety, comfort and stability are higher than ordinary tires. Since the vacuum tire has no tube, it is troublesome to repair, and the repair cost is high, so try to avoid being punctured by sharp objects during use. Once the tire is punctured and leaks air, it is easy to cause a safety hazard. At present, the vacuum tires of motorcycles usually use rubber nails for air leakage, but the gap must be enlarged when the rubber nails are used. This not only artificially destroys the tires, but also causes air leakage after re...
