Production process of sealant for tire and steel rim and sealant

Abstract

The invention discloses a production process of a sealant for a tire and a steel rim and the sealant, and belongs to the field of adhesives. The sealant disclosed by the invention is prepared from the following materials in parts by weight: 20 to 40 parts of butadiene styrene rubber, 60 to 80 parts of natural rubber, 5 to 25 parts of carbon black, 5 to 25 parts of white carbon black, 1 to 20 parts of zinc oxide, 1 to 20 parts of stearic acid, 1 to 20 parts of sulphur, 1 to 15 parts of accelerator and 280 to 300 parts of solvent. The sealant provided by the invention can effectively solve the problem of a phenomenon of air leakage caused by a gap between the steel rim and the tire, which is generated due to micro deformation of the steel rim, and repair cost is greatly reduced.

Description

technical field [0001] The invention belongs to the field of adhesives, and in particular relates to a production process of a sealant for tires and steel rings and the sealant. Background technique [0002] Tire is one of the important parts of the vehicle. It is in direct contact with the road surface, and together with the suspension of the vehicle, alleviates the impact of the vehicle while driving, ensuring that the vehicle has good ride comfort and driving comfort, and ensures that the wheels and the road surface have Good adhesion, improve the traction, braking and passability of the vehicle, and play a very important role in bearing the weight of the vehicle. [0003] After years of development, tires have evolved from simple internal pneumatic tires to radial tires to atomic tires, that is, tubeless tires. This kind of tire is not easy to heat up during high-speed driving. When the tire is pierced by nails or sharp objects, The air leakage is slow, and it can conti...

Problems solved by technology

[0004] The difference between tubeless tires and ordinary tires is that there is no inner tube, and the air is directly pressed into the outer tire, so there must be a good seal between the tire and the rim. When the vehicle tire is scratched, the situation is not too serious, but the steel ring of the tire However, when a small amount of deformation occurs, it will cause the tire to not completely fit the steel rim, resulting in air leakage, leaving a safety hazard. It is more difficult to repair the tire rim, and it is even more difficult to correct the small deformation. If the entire steel ring needs to be replaced, the burden on the owner is heavy

[0005] In the patent No. CN104974685A, an adhesive and its preparation method are disclosed, which solves the problem that nitrile rubber is difficult to bond to natural rubber, but it has no effect on the sealing between the tire and the steel ring. At the same time, in the patent No. CN103642447A Disclosed in the vulcanized rubber fast bonding rubber metal thermal vulcanization type adhesive, can bond rubber and metal, but its use conditions and use effect are difficult to solve the existing problems
