Embodiment 1

[0040] Proportion and components of self-sealing tire leak-trapping glue (based on weight %): 45% thermoplastic elastomer, 43% tackifier, 8% plasticizer, 1% anti-aging agent and antioxidant, 3% filler; Weigh thermoplastic elastomer SEBS 600g, thermoplastic elastomer SEPS 300g; tackifier: petroleum resin (C5) 860g; plasticizer: aromatic oil 120g, dibutyl phthalate (DBP) 40g; antioxidant 26410g, anti-aging Agent RD 10g; filler: carbon black 60g.

[0041] The preparation method is as follows: using material crushing equipment to crush the solid material into particles of <150 mesh; using a continuous mixing device planetary mixer to uniformly mix the crushed solid material and liquid material, and then measure and bag the mixture after uniform mixing.

Embodiment 2

[0043] Proportion and components of self-sealing tire leak-tight glue (based on weight %) 50% thermoplastic elastomer, 40% tackifier, 7% plasticizer, 1% antioxidant, filler 2%; weigh thermoplastic elastomer Body SEBS 800g, thermoplastic elastomer SEPS 200g; tackifier: C5 / C9 petroleum resin 800g; plasticizer: aromatic oil 100g, diisobutyl phthalate (DIBP) 40g; antioxidant 2246 10g, antioxidant 264 10g; filler: aluminum hydroxide 20g, carbon black 20g.

[0044] The preparation method is as follows: using material crushing equipment to crush the solid material into particles of <150 mesh; using a continuous mixing device propeller agitator to uniformly mix the crushed solid material and liquid material, and measure and pack the powder after mixing evenly.

Embodiment 3

[0046] Proportion and components of self-sealing tire leak-tight glue (based on weight %): 49% thermoplastic elastomer, 40% tackifier, 5% plasticizer, 1% anti-aging agent and antioxidant, 5% filler; Weigh thermoplastic elastomer SEBS 580g, thermoplastic elastomer SEPS 400g; tackifier: petroleum resin (C5 / C9) 800g; plasticizer: aromatic hydrocarbon oil 50g, diisobutyl phthalate (DIBP) 50g; antioxidant 4010 10g, antioxidant 264 10g; filler: carbon black 60g, aluminum hydroxide 40g.

[0047] The preparation method is as follows: using material crushing equipment to crush the solid material into particles of <150 mesh; using a continuous mixing equipment high-shear disperser to uniformly mix the crushed solid material and liquid material, and measure and pack the powder after mixing evenly.

Abstract

The invention relates to self-sealed tyre leak-repairing glue for security upgrade of an automobile tyre. The self-sealed tyre leak-repairing glue comprises the following components in percentage by weight: 40-60% of a thermoplastic elastomer, 34-51% of a tackifier, 5-8% of a plasticizer, and/or 0.5-1.5% of an antiaging agent and 2-5% of filler. The self-sealed tyre leak-repairing glue is sprayed on the inner wall of the tyre by an automobile tyre glue sprayer, the inner wall of the tyre is not destructively processed, and the release agent is just removed to clean and dry the inner wall of the tyre. The self-sealed tyre leak-repairing glue which is thicker than 3.5mm is sprayed on the whole or the crown part of the inner wall of the tyre, so that the tyre is upgraded to the tyre which can normally work from a low temperature of -40 DEG C to a high temperature of 120 DEG C. The tyre has the performances of elasticity resistance, leak prevention and prick resistance. The invention further discloses a preparation method of the self-sealed tyre leak-repairing glue.

Description

technical field [0001] The invention relates to a self-sealing tire leak-trap glue used for safety upgrading of ordinary automobile tires and a manufacturing method thereof. Background technique [0002] At present, there are two types of car wheels used in vehicles, one with inner tubes and the other without tubes. At present, almost all of the passenger vehicles use tubeless wheels. The country requires gradual promotion of heavy-duty vehicles. Use tubeless car wheels. Because the tubeless car wheel has the advantages of good heat dissipation, softness, sealing, comfortable ride, good performance and long interval between inflation and use, but when the tire of the tubeless car wheel is punctured by a sharp object, due to the sharp object remaining on the car In the tire body, the high-pressure gas of the car tire will leak out or blow out at the punctured part; when the sharp object pierces the car tire and breaks away from the car tire, the high-pressure gas in the tube...
