Fighter plane tire tread rubber and preparation method thereof

Abstract

The invention belongs to the technical field of tire rubber and in particular relates to fighter plane tire tread rubber and a preparation method thereof. The fighter plane tire tread rubber is prepared from the following raw materials in parts by weight: 80 parts of oil-extended natural rubber, 10 parts of solution polymerized butadiene styrene rubber, 10 parts of rubber powder, 15 to 35 parts of carbon black N330, 17 to 21 parts of schungite, 13 to 15 parts of para-aramid pulp, 3.0 to 3.6 parts of nano calcium carbonate, 0.7 to 1.1 parts of silicon dioxide powder, 1.2 to 1.4 parts of an anti-ageing agent 6PPD, 1.1 to 1.4 parts of an anti-ageing agent JOL, 0.7 to 0.8 part of xanthogenate and 3.0 to 3.4 parts of sulfur. The tread rubber provided by the invention has abrasive resistance, thermogenesis resisting property, herringbone cutting opening resistance and chunking resistance of a tire at a high temperature.

Description

technical field [0001] The invention belongs to the technical field of tire rubber, and in particular relates to a fighter tire tread rubber and a preparation method thereof. Background technique [0002] When a fighter takes off and lands with an abnormal overload, due to the large deformation and load applied to the tread, the heat generated by the tread will be extremely large, so it is necessary to prevent the adhesive peeling between the adhesive surfaces of the retreaded tread. In addition, under normal circumstances, it is required to prevent the phenomenon of chipping caused by large deformation such as sharp turns during taxiing. At the same time, it is also necessary to prevent early wear of the tread due to severe skidding during landing and scratches on the tread from the runway during taxiing, especially herringbone cuts. [0003] At the moment when the fighter plane lands, when the tires are suddenly subjected to high loads and high slipping speeds, the surfac...

AI Technical Summary

Problems solved by technology

[0004] If the temperature of ordinary tire tread rubber reaches above 200°C, the main chain and network structure of the rubber component will be broken sharply, resulting in a significant decrease in reinforcement

As a method to ensure such high-temperature reinforcement, run-flat tire sidewall reinforcing rubber has been developed. In order to enable this sidewall reinforcing rubber to support weight when the tire leaks, only consideration is given to ensuring high temperature. The modulus of elasticity does not consider the wear resistance, herringbone cut resistance and collapse resistance, so it cannot be used as a tread compound
