Formula and production process of tire with new outer contour

Abstract

The invention relates to a formula and a production process of a tire with a new outer contour. The formula comprises a tread, a tire shoulder and a tire sidewall, the curve of the tread is flat, the curvature of the tire shoulder and the tire sidewall is increased, radians are formed outwards, and the tire is prepared from the following raw materials in parts by weight: 70-100 parts of a natural rubber, 0-30 parts of a synthetic rubber, 3.0-5.0 parts of activated zinc oxide, 1.5-3 parts of a stearic acid, 50-60 parts of carbon black, 3-5 parts of an anti-aging agent, 1.5-3.0 parts of a silane coupling agent, 1.2-2.0 parts of an accelerant, 0.8-1.8 parts of sulfur and 0.1-0.3 part of a scorch retarder. The process has the beneficial effects that the DOCT technology, namely the deformation optimization control technology, is adopted, the deformation trend of the radial tire subjected to inflation loading is controlled by changing the curvature of the outer contour of the tire, adopting the high-elasticity low-deformation rubber formula technology in a matched mode and adopting the high-precision manufacturing process, and the deformation displacement of component materials is reduced so that the performance of the tire is improved. Tire rolling heat generation is effectively reduced, abnormal abrasion, especially eccentric abrasion, in the whole life cycle is reduced, the tire failure rate is reduced, and the service life of the tire is prolonged.

Description

technical field [0001] The invention relates to the technical field of deformation optimization control of truck tires and bus radial tires, in particular to a formula of a new outer profile tire and a preparation process thereof. Background technique [0002] Existing truck tires and bus radial tires have obvious tire rolling heat generation during use, and abnormal wear throughout the life cycle, especially partial wear, is also relatively serious, so the tire failure rate is high and the service life of the tire is not long enough . Contents of the invention [0003] In order to solve the problems raised in the above-mentioned background technology, the purpose of the present invention is to provide a formula for a new outer profile tire and its preparation process, adopt deformation optimization control technology, change the curvature of the tire outer profile, and use high elasticity and low deformation rubber formula Technology, plus high-precision manufacturing pr...
