Abstract

The invention relates to a good-cutting-resistance wear-resistant rubber material for tread rubber of a meridian aircraft tire. 1# smoke sheet rubber is taken as a main material, a novel ultra-wear-resistant VULCAN 10H carbon black is taken as a reinforcing agent, and novel anti-tear resin is added into a formula, so that the cutting resistance of the rubber material is enhanced; and by adding nano-zinc oxide, white carbon black AS-70, a silane coupling agent, a heat stabilizer, an anti-reversion agent and the like, the tread rubber of the tire has the characteristics of good cutting resistance, wear resistance and heat stability and further has the advantages that the tensile strength is relatively high, 300% of stress at definite elongation is realized, the adhesive strength with a belted layer is good, scaly figures are unlikely to be formed, the wear resistance is good, and the service life is long.

Description

technical field [0001] The invention relates to a polymer material, in particular to a radial aviation tire tread rubber material with good cutting resistance and wear resistance. Background technique [0002] The service conditions of radial aviation tires are more severe than those of bias tires. They need to bear greater loads and have higher taxiing and take-off speeds. Degradation will reduce the wear resistance and other properties of the tread rubber, and even cause failures such as delamination with the belt layer and tread rejection. Therefore, the tread rubber needs to have good wear resistance and thermal stability, and good adhesion to the belt layer. combined strength. Due to the small stretch of the belt layer, radial aviation tires have high crown rigidity and high stress. When taxiing on an airport runway with sharp drainage grooves, the tread rubber is easily cut to form herringbone cuts—commonly known as fish scales. Radial aviation tires take off and lan...
