Novel tire and preparation method thereof

Abstract

The invention provides a novel tire and a preparation method thereof. The novel tire comprises a presulfurized tire body, presulfurized tire tread rubber and middle cushion rubber. The middle cushion rubber is arranged between the presulfurized tire body and the presulfurized tire tread rubber, and the presulfurized tire body, the middle cushion rubber and the the presulfurized tire tread rubber are bonded and sulfurized together. The preparation method of the novel tire is that the middle cushion rubber, and the presulfurized tire body and the presulfurized tire tread rubber are bonded together, molded and sulfurized, so that the novel tire is made, wherein the sulfurization temperature is approximately 90-120 DEG C, the sulfurization pressure is approximately 0.5-0.7 MPa, and the sulfurization duration is determined according to the thickness of the tread rubber and the sulfurization speed of the middle cushion rubber. By applying the novel tire and the preparation method thereof, the structure of the existing traditional novel tire and the manufacturing method thereof are changed, the problem of uneven sulfurization of tires having thick patterns is solved, the physical and mechanical properties of the novel tire are improved, the service life is prolonged, the wear resistance and puncture resistance are superior to the traditional novel tire, the use cost of the tire is reduced, the difficulty in the tire manufacturing technology in huge engineering is lowered, and richer tire pattern styles are conveniently provided.

Description

technical field [0001] The invention relates to an unused new tire for a wheel and a preparation method of the new tire, belonging to the technical field of new tires. Background technique [0002] Rubber tires are widely used on various vehicles. New tires refer to tires that have not been used and are produced from original materials, not remanufactured tires that have been retreaded from old tires that have been used. The carcass used for low-temperature pre-vulcanized remanufactured tires (commonly known as cold-turned tires) refers to the old tire carcass formed after the use of new tires. , forming a cold tire. [0003] In the existing new tires, the unvulcanized crown rubber is coated on the unvulcanized carcass to form a green tire, and then the green tire is put into a split mold vulcanizer with a pattern, and the crown rubber and the carcass rubber are simultaneously vulcanized to form new tires. The ratio of the vulcanization pressure (about 2.6MPa) to the vul...

AI Technical Summary

Problems solved by technology

[0007] Different conditions of use need to choose tires with different pattern styles, but the price of pattern molds for vulcanizing machines is high, and tire factories only provide a limited number of patterns, and the pattern update speed is very slow

In addition, in the existing tire manufacturing process, it is cumbersome to replace the pattern mold of the active mold vulcanizer, and it is necessary to complete the order for the same pattern before replacing the pattern mold

Often, orders placed earlier will be delivered later than orders placed later, causing customers to complain
