Special semi-steel radial tire for microvan and preparation method of special semi-steel radial tire

Abstract

The invention relates to a special semi-steel radial tire for a microvan and a preparation method of the special semi-steel radial tire. The special semi-steel radial tire is prepared from the following raw materials in parts by weight: 40-60 parts of natural rubber, 20-30 parts of solution polymerized styrene-butadiene rubber, 15-20 parts of butadiene rubber, 35-40 parts of nitrile rubber, 1.5-2.5 parts of glass fiber, 20-40 parts of white carbon black, 2-4 parts of a silane coupling agent, 35-45 parts of carbon black, 5-8 parts of aromatic hydrocarbon oil, 4-8 parts of zinc oxide, 1.5-4.5 parts of stearic acid, 1-5 parts of an anti-aging agent, 1-3 parts of microcrystalline wax, 10-20 parts of functional resin, 2-5 parts of a carbon black dispersing agent, 1.5-3.5 parts of sulfur, 1-3 parts of an accelerant, 0.1-0.3 part of a scorch retarder, 1.5-3.5 parts of benzoic acid, 7.8-12.4 parts of phenolic resin, 5.5-8.3 parts of C5 petroleum resin and 5.5-8.5 parts of a mixture of rhenosin TT100, rhenosin PP and a phosphate plasticizer. The special semi-steel radial tire for the microvan is thick in tire side, not easy to crack, small in tire side deformation, good in lateral stability and good in road holding force, the noise is reduced, the wear resistance is improved, the comfort is improved, and the special semi-steel radial tire is low in cost, green, environmentally friendly and fuel-efficient.

Description

technical field [0001] The invention relates to a special semi-steel radial tire for mini vans and a preparation method thereof, belonging to the technical field of semi-steel radial tires. Background technique [0002] As we all know, semi-steel radial tires have the characteristics of low rolling resistance, fuel saving, thin sidewalls and small radial deformation. These two features are beneficial to reduce tire internal wear and reduce rolling resistance. The rolling resistance of radial tires is 20%-30% smaller than that of ordinary bias tires, which can save fuel by 5%-10%. The service life of the tire is 30%-40% higher than that of the bias tire. [0003] However, radial tires are not all-round tires. The common defects of radial tires on the market are: thin sidewalls, easy to crack, large sidewall deformation, poor lateral stability, high manufacturing requirements and high cost of radial tires. Especially the semi-steel radial tires that are used for minivans hav...

Problems solved by technology

[0003] However, radial tires are not all-round tires. The common defects of radial tires on the market are: thin sidewalls, easy to crack, large sidewall deformation, poor lateral stability, high manufacturing requirements and high cost of radial tires

Especially the semi-steel radial tires used for minivans also have the above defects, in addition to the disadvantages of poor grip, high noise and poor wear resistance
