Abstract

The invention relates to a formula for belt coating rubber of an all-steel engineering radial tire. The formula is characterized in that a rubber material contains the ingredients: natural rubber, styrene-butadiene rubber, zinc oxide, stearic acid, carbon black, a post vulcanization stabilizer HTS, an anti-aging agent 4020, an anti-aging agent RD, resorcinol, hexamethoxy methylmelamine, cobalt neodecanoate, N-tert-butyl-2-benzothiazole sulfenamide, insoluble sulfur, a vulcanizing agent DTDM, Koresin resin, aromatic hydrocarbon oil and the like. The milled rubber material is high in adhesion with steel wires, low in heat generation and excellent in puncture resistance, and thus the service life of the tire is prolonged.

Description

technical field [0001] The invention relates to a rubber compound for the belt layer of an all-steel engineering radial tire, which is mainly used for the rubber compound for the belt layer of all-steel engineering radial tires such as 30.00R51 and 40.00R57. Background technique [0002] In 1946, the French Michelin Company invented the radial tire, which brought revolutionary changes to the tire industry. Later, this technology was extended to various tires, and in 1959, the world's first radial tire was manufactured. The advent of radial tires has shown incomparable superiority compared with bias tires. Therefore, the development of radial tires is the earliest and the fastest in Western Europe. As early as 1972, France was almost 100% radial, and by the end of 1989, the Western European tire market had been 100% radial. [0003] All-steel OTR tires have the advantages of fuel saving, low heat generation, high mileage, large load capacity, good wear resistance, cutting ...
