Fast vulcanizing tire repair adhesive and production process thereof

Abstract

The invention relates to a fast vulcanizing tire repair adhesive and a production process thereof. The fast vulcanizing tire repair adhesive comprises a tire tread repair adhesive formula, a tire beadrepair adhesive formula and a tire side repair adhesive formula, wherein the basic formula comprises by mass: 100 parts of a mixed rubber master batch, 2-3 parts of an accelerator M, 1-2 parts of anaccelerator D, 1.2-2 parts of an overspeed accelerator PZ, 8-12 parts of operating oil and 1.1-1.5 parts of sulfur. Compared with the traditional tire repair adhesive, the main advantage of the fast vulcanizing tire repair adhesive is that the fast vulcanizing tire repair adhesive can complete vulcanization in a short time at low temperature, compared with a similar repair adhesive, the vulcanization time is shortened from traditional several hours to 20 minutes at the same vulcanization temperature, and the production efficiency of the tire repair process is greatly improved. By using the mixed rubber master batch, the production workload of the fast vulcanizing tire repair adhesive is reduced, the sulfur and the accelerants are added to a small open mill, and operation is performed according to a specific process, so that various components in the formula can be dispersed more evenly, and targeted personalized production can be carried out according to repair parts.

Description

technical field [0001] The invention relates to the technical field of production of self-made tire repair rubber, in particular to a rapid vulcanization tire repair rubber and its production process. Background technique [0002] When the finished tires are inspected in the quality inspection process, according to the company's judgment standards, some products with minor appearance defects can still be downgraded for use after surface repairs. When repairing the appearance, the rubber material at the defect position should be cut off with a knife first, and the position should be filled with repair glue, and then vulcanized at a low temperature (120°C) on a special small flat vulcanizer, and then polished and sprayed after the vulcanization is completed Wait for appearance repair operations. The amount of glue used for this repair glue is large, and it is generally required that the glue is soft and easy to fill. [0003] At present, major tire factories generally use th...

Problems solved by technology

[0004] The purpose of the present invention is to provide a kind of rapid vulcanization tire repair rubber and its production process, to solve the present problems proposed in the above-mentioned background technology. At present, what the major tire factories generally use is commercially available imported A / B glue, which is divided into A , B two kinds of components, use the extruder to mix the two kinds of glues A and B before use, and use it as a piece
