Abstract

The invention discloses a bead wire coating compound for an aircraft radial-ply tire, which is prepared by mixing the following raw materials in part by weight: 50 to 100 parts of butadiene styrene rubber, 0 to 50 parts of natural rubber, 30 to 70 parts of powerful powder, 35 to 65 parts of general purpose furnace black N660, 3 to 10 parts of zinc oxide, 0 to 4 parts of stearic acid, 1 to 4 partsof p-Phenylenediamine antioxidant 4020 or 4010NA, 1 to 4 parts of acetone-amine condensation product antioxidant BLE or RD, 1 to 8 parts of insoluble sulfur IS-60 or IS-90, 1 to 3 parts of sulfenamide accelerator NOBS or DZ, 0.5 to 3.0 parts of adhesive AIR-101, 0.5 to 3.0 parts of cobalt boroacylate or cobalt decanoate and 0 to 2.0 parts of tackifying resin DHJH-B through a banbury. The compoundhas good elongation, elasticity and adhesiveness and particularly good bonding strength after thermal ageing, and can meet the requirement of a hexagonal steel ring production process.

Description

technical field [0001] The invention relates to tire bead rubber materials, in particular to aviation radial tire bead steel wire hanging rubber materials. Background technique [0002] At present, the commonly used aviation tires are of oblique structure, and the technical performance and physical properties of the bead wire hanging glue formula of the oblique structure aviation tires cannot meet the technical and physical performance requirements of the hexagonal steel ring production of radial aviation tires. Contents of the invention [0003] The purpose of the present invention is to provide a tire that can adapt to the production process of the hexagonal steel ring of aviation radial tires, maintain a high bonding strength with the bead steel wire before and after heat aging, and have high tensile properties of the rubber material and good elasticity. Ring steel wire hang glue material. [0004] The sizing material of the present invention is made by mixing the fo...
