Abstract

The invention discloses an aircraft tire buffer rubber containing a resorcinol-formaldehyde adhesion system. The aircraft tire buffer rubber is prepared from the following components in parts by weight: 100 parts of natural rubber, 4-6 parts of zinc oxide, 1.0-2.5 parts of stearic acid, 2-3 parts of anti-aging agent, 3-5 parts of high-content aromatic oil, 35-50 parts of carbon black, 1.0-2.5 parts of adhesive RF-90, 1.5-5 parts of adhesive RA-65, 1-3 parts of tackifier TKM-M, 0.5-1.5 parts of vulcanizing activator Z-311, 2.0-3.0 parts of insoluble sulfur, 1.0-2.0 parts of sulfenamide accelerant and 0.1-0.2 parts of scorch retarder, wherein the carbon black is combination of N330 carbon black and N550 carbon black. The buffer layer rubber prepared according to the formula disclosed by the invention has high adhesive strength with a nylon cord fabric, high physical properties and bonding strength retention rate after thermal ageing.

Description

technical field [0001] The invention relates to an aviation tire buffer rubber containing a meta-formaldehyde adhesive system, which belongs to the field of tire manufacturing. Background technique [0002] The buffer layer of aviation tires is a film with or without cords between the tread rubber and the ply. Its main function is to absorb the vibration and impact from the direction of the tread and reduce the impact of the tire on take-off or when the aircraft takes off. The traction force and braking force acting on the carcass during landing and sliding enhance the adhesion between the tread rubber and the carcass. Aviation tires have the characteristics of large load, high speed, large sinking, large deformation, and high inflation internal pressure. It is required that the buffer layer rubber not only has a good bonding effect with the tread and carcass, but also has good thermal conductivity. Resistance, aging resistance, fatigue resistance under multiple deformation...
