Embodiment 1

[0046] Proportion and components of heat-resistant polymer self-sealing adhesive (based on mass percent): 100 thermoplastic elastomer, 86.5 tackifier, 11.7 plasticizer, antioxidant and anti-aging agent 3 in total, foaming agent 19; weigh Thermoplastic elastomer SIS80, thermoplastic elastomer SEBS20; tackifier: terpene resin 75, polyisobutylene 11.5; plasticizer: naphthenic oil 11, diisooctyl phthalate 0.7; antioxidant 4010A1.5, antioxidant 10761.5; Blowing agent: AC19.

[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.

Embodiment 2

[0049] Proportion and components of heat-resistant polymer self-sealing adhesive (based on mass percent): 100 thermoplastic elastomer, 75 tackifier, 6 plasticizer, 1 antioxidant, foaming agent 4; weigh thermoplastic elastomer SIS85 , thermoplastic elastomer SEBS15; tackifier: rosin glyceride 65, polyisobutylene 10; plasticizer: naphthenic oil 5.5, diisooctyl phthalate (DIOP) 0.5; antioxidant 10100.5, antioxidant 3000.5; Foaming agent: ADC4.

[0050] 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.

Abstract

The invention discloses temperature-resistant macromolecule self-seal rubber and a manufacturing method thereof, and the self-seal rubber is composed of the following components in parts by mass: 100 parts of thermoplastic elastomer, 75-86.5 parts of tackifier, 6-11.7 parts of plasticizer, 1-3 parts of antiaging agent and / or antioxidant and 4-19 parts of foaming agent. The temperature-resistant macromolecule self-seal rubber is sprayed on the inner wall of a tire by using an automobile tire rubber sprayer without performing any traumatic processing on the inner wall of the tire and only performing cleaning and drying treatment on the inner wall of the tire to remove the release agent, a layer of temperature-resistant macromolecule self-seal rubber with thickness of more than 3.5mm is sprayed on all of the inner wall or partial crown type body of the tire, and then the tire is upgraded that the tire can normally work within low temperature of minus 40 DEG C to high temperature 120 DEG C, and has the bullet-proof, leak-proof and puncture-proof performances. The invention further discloses a manufacturing method of the temperature resistant macromolecule self-seal rubber.

Description

technical field [0001] The invention relates to a temperature-resistant polymer self-sealing 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 ...
