Abstract

The invention discloses an aerotire wire skim coating formula. The formula contains the following materials(based on weight portion): 80-90 portions of natural gum, 10-20 portions of cis-butadiene rubber, 4-6 portions of adhesive RS, 2-4portions of age inhibitor, 100-125 portions of soft black carbon, 3-5portions of curing agent, 0.5-1portions of accelerant, 1-3 portions of adhesive A, 1-3 portions of adhesion promoter AIR series, 1-2 portions of physical tackifier, 5-10 portions of promoting agent and 5-10portions of plasticizer. The rubber material with the formula is capable of making the surface of the steel wire be good in rubber conglutination, thus obviously improving the adhesive force between the skim coating and the steel wire and solving the problem that the rubber material is difficult to adhere to the roller in the production process.

Description

Technical field: [0001] The invention relates to a polymer material, in particular to a formula for hanging rubber for steel wire of an aviation tire. Background technique: [0002] The skeleton material used in aviation tires contains steel wire and other materials. At present, the steel wire and rubber usually have the disadvantages of poor adhesion, small amount of glue attached, and a sharp drop in adhesion after heat aging in the production of tires. Invention content: [0003] The object of the present invention is to disclose a formula for hanging rubber for steel wires of aviation tires. The rubber compound in the formula can make the surface of the steel wires adhere to the glue well, and the hanging glue and the steel wires can be bonded firmly. [0004] The aviation tire steel wire hang glue formula of the present invention is made up of the raw material of following weight ratio: [0005] Natural rubber 80~90 [0006] Butadiene rubber 10~20 [0007] Adhesive...
