Leak-proof patch of tubeless tire and production process thereof

Abstract

The invention belongs to the technical field of tubeless tires and relates to a leak-proof patch of a tubeless tire and a production process thereof. The production process comprises the steps of weighing raw materials; heating a reaction kettle to 130-250 DEG C, then putting the weighed raw materials into the reaction kettle in batches or once, and stirring to obtain uniform liquid raw materials; laying a layer of release paper at the bottom of a box body, firstly injecting the liquid raw materials into the box body to form a layer of liquid raw materials, further laying a layer of release paper on the upper surface of the layer of liquid raw materials in the box body, then flattening the liquid raw material injected into the box body, and cooling to room temperature to form the leak-proof patch of the tubeless tire. The leak-proof patch of the tubeless tire is prepared from the following substances in parts by weight: 29-49 parts of elastomer, 41-52 parts of tackifier, 19-28 parts of rubber additive, 9-18 parts of leak-proof additive and 1-4 parts of dyeing agent. The production process provided by the invention has the advantages of simple production process, as well as convenience in use and convenience in storage and transportation of the produced leak-proof patch of the tubeless tire.

Description

technical field [0001] The invention belongs to the technical field of tubeless tires, and relates to a leak-proof patch for tubeless tires and a production process thereof. Background technique [0002] At present, there are two types of tires in the use of tires, one is tubeless tires, and the other is tubeless tires. At present, tubeless tires are basically used in passenger vehicles. Tube tires. Because the tubeless tire has the characteristics of good heat dissipation, softness, good comfort performance, good sealing performance, and long intervals after inflation, but when the tubeless tire is punctured by a sharp object, within a short period of time, due to the sharp object remaining On the carcass, the high-pressure gas in the tire will slowly leak outward at the punctured part. When the sharp object pierces the tire and leaves the carcass, the high-pressure gas in the tubeless tire will quickly reduce the pressure due to air leakage. The consequences of this happ...

Problems solved by technology

[0004] The use of the anti-leakage mixture of the above-mentioned tubeless tire then all is that the anti-leakage mixture of the tubeless tire is melted and mixed evenly and then directly sprayed or poured on the inner surface of the tire. Need to invest a lot of money to buy spraying or pouring equipment for tubeless tires; second, installing spraying or pouring equipment for tubeless tires requires a large production site and space in the workshop; third, skilled workers are needed in production, making production costs Greatly improved; Fourth, it has few uses and cannot be used as a patch for tire repair
