Abstract

The invention discloses an aviation tire reinforcing layer adhesive of high adhesive strength, prepared through two-stage mixing performed by a mixer by using main materials: 80-90% of ribbed smoked sheet 1#, 10-20% of styrene butadiene rubber 1500, 30-40% of new process high structural and high wear resistant carbon black, 5-10% of silica, and silane coupling agent KH-560, adhesion promoter AIR-201, adhesive SL-3090, p-phenylenediamine antioxidant 4010NA, antioxidant RD, sulfenamide accelerator and scorch retarder CTP, . The invention has properties of high initial adhesive strength, high adhesive after aging, high tensile strength, high tensile modulus and low heat production, and can meet property requirements of high speed and high load of future new model tires; and the adhesive strength between rubber before and after aging and nylon cord is high, has high hardness and tensile, low heat production, and can improve the dynamic property of tires, thereby preventing tires from delaminating, blowing up and rejecting of tread, and improving the safety performance of aviation tires.

Description

technical field [0001] The invention relates to a polymer material, in particular to an aviation tire reinforcing layer hanging glue with high bonding strength. Background technique [0002] With the development of the aviation industry, the take-off speed and load of the aircraft continue to increase, the temperature of the tire is high, and the centrifugal force is large. At present, the adhesive strength of the rubber on the reinforcement layer of the aviation tire is not enough. On the other hand, the safety of use and the service life will be reduced. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide an aviation tire reinforcement layer hanging glue with high bonding strength, which can better meet the performance requirements of high-speed and high-load tires of new models in the future; High strength, high hardness, high constant elongation and low heat generation, can improve the dynamic performance of tires, prevent tire delamin...
