Heat-conducting high-heat-conductivity aircraft tire tread rubber

Abstract

The invention relates to a heat-conducting high-heat-conductivity aircraft tire tread rubber which is prepared from the following raw materials in parts by weight: 70-100 parts of 1# bacon rubber, 30-0 parts of styrene-butadiene rubber (SBR) 1500, 46-52 parts of super-wear-resistance carbon black N115, 5-8 parts of precipitated white carbon black, 0.5-3 parts of silane coupling agent Si69, 1-2 parts of heat stabilizer HS-80, 0.5-1.0 part of anti-reversion agent WK-901, 1-3 parts of multifunctional vulcanization activator ZNZB746, 3-5 parts of zinc oxide, 1-3 parts of p-phenylenediamine anti-aging agent 4020, 1-2 parts of ketoamine anti-aging agent S-RD, 1.5-2.5 parts of insoluble sulfur HD OT 20 or IS-60, 0.8-2.0 parts of sulfenamide accelerator NS or NOBS and 3-10 parts of functional nano rubber additive GTR-M02. The tread rubber has the characteristics of favorable heat conductivity, favorable electric conductivity, favorable wear resistance and high heat stability, and has the advantages of higher tensile strength, higher elongation at break and higher 300% stress at definite elongation.

Description

technical field [0001] The invention relates to a polymer material, in particular to an aviation tire tread rubber with good thermal and electrical conduction. Background technique [0002] With the continuous improvement of the load, take-off and landing speed of new aircraft, the performance requirements of tires are getting higher and higher. Because rubber is a poor conductor of heat, the existing aviation tire tread rubber has the disadvantage of poor heat conduction. Aviation tires take off and land at high speed under high load. When the tire is in use, the tread rubber part is in a high temperature state due to high heat generation. Due to the high temperature, the rubber degrades, which reduces the wear resistance of the tread rubber, and because Internal high temperature reduces the bonding strength between the rubber material and the skeleton material, and quality problems such as internal voids and bulges in the reinforcing layer and other parts are prone to occ...

Because rubber is a poor conductor of heat, the existing aviation tire tread rubber has the disadvantage of poor heat conduction

Aviation tires take off and land at high speed under high load. When the tire is in use, the tread rubber part is in a high temperature state due to high heat generation. Due to the high temperature, the rubber degrades, which reduces the wear resistance of the tread rubber, and because Internal high temperature, the bonding strength between the rubber material and the skeleton material decreases, and quality problems such as internal voids and bulges in the reinforcing layer and other parts are prone to occur, which affects the flight safety of the aircraft
