Problems solved by technology

The traditional repair method is extremely wasteful of resources, especially in terms of after-sales service, it needs to have its own vulcanization device, which is very troublesome, and with the use of the tire, the surface of the tire cannot be repaired. Repairing air leaks requires grinding, gluing, and pasting, which is labor-intensive, time-consuming, and labor-intensive

Abstract

The invention discloses a repair adhesive for tires and a preparation method of the repair adhesive. The repair adhesive is prepared from the following raw materials in parts by weight: 9-18% of natural rubber, 8-16% of cis-butadiene rubber, 5-10% of styrene-butadiene rubber, 10-20% of polyterpene phenolic resin, 8-16% of C5-C9 copolymerized petroleum resin, 15-30% of carbon black, 2-4% of silicondioxide, 10-20% of nano calcium carbonate, 40%-66% of a solvent and 0.2%-0.4% of an antioxidant. The repair adhesive provided by the invention has the excellent characteristics of good bonding strength, fast drying, high solid content, wear resistance, high-temperature resistance, cold resistance, water resistance, acid and alkali resistance and the like, is used for repairing cracks, scratches and holes in tire surfaces and tire surface damages, can effectively protect tires, and can also repair air leakage from tack holes of the tires.

Description

technical field [0001] The invention relates to the field of repair glue, more specifically, a tire repair glue and a preparation method thereof. Background technique [0002] At present, after the tires are produced, due to various factors, there will always be some defects in a considerable part, mainly manifested in the lack of rubber and exposed lines. The traditional remedial method is to grind the defective part, refill the rubber, re-mold and vulcanize or vulcanize with a local vulcanizer. The traditional repair method is extremely wasteful of resources, especially in terms of after-sales service, it needs to have its own vulcanization device, which is very troublesome, and with the use of the tire, the surface of the tire cannot be repaired. The hole leak repair needs to be polished, glued, and glued, which is labor-intensive, time-consuming, and labor-intensive. Contents of the invention [0003] In order to make up for the above deficiencies, the invention prov...
