Problems solved by technology

At present, the typical bonding method used in the tire manufacturing industry is the direct bonding method, that is, the bonding system is directly added to the rubber compound, and the rubber compound and the steel cord are firmly bonded during the thermal vulcanization process. Cobalt salts are commonly used as cobalt promoters, but there are no reports on the adhesion promoters and adhesion promoters.

Abstract

The invention discloses a sizing material adhered to a belt ply steel wire of a truck radial tire and a preparation method, relates to a sizing material and a preparation method thereof, and discloses a sizing composition adhered to the belt ply steel wire of the truck radial tire. The sizing material comprises the following components by weight: 100 parts of natural rubber, 40-60 parts of carbon black N330, 3-5 parts of white carbon black, 8-10 parts of zinc oxide, 2-4 parts of anti-aging agent 4010NA, 3-6 parts of adhesive CS-964, 0.8-1.2 parts of adhesion promoter, 0.5-2.5 parts of R-80, 4-6 parts of insoluble sulfur, 1-2 parts of promoter NOBS (N-(Oxidiethylene)-2-benzothiazolyl sulfenamide), 0.1-1 part of anti-scoring agent CTP (Cyclohexylthiophthalimide) and 0.1-1 part of adhesion promoter P-1. By using the technical scheme, the adhesion performance of the sizing material and the copper-plated steel wire can be enhanced, and the coating quality is also better.

Description

technical field [0001] The invention relates to a sizing material and a preparation method thereof, in particular to a sizing material bonded to a belt layer steel wire of a load-bearing radial tire and a preparation method thereof. Background technique [0002] The belt speed layer of a radial truck tire is composed of copper-plated steel cords, and its durability depends on the adhesive performance of rubber and metal. Therefore, the adhesive performance of copper-plated steel cords and the rubber in direct contact with them very important. At present, the typical bonding method used in the tire manufacturing industry is the direct bonding method, that is, the bonding system is directly added to the rubber compound, and the rubber compound and the steel cord are firmly bonded during the thermal vulcanization process. Cobalt salts are widely used as cobalt promoters, but there is no report on the adhesion promoters and adhesion promoters used in combination. Contents...
