Machining method for pre-vulcanizing lining layer of all-steel tire by utilizing electron beams

Abstract

The invention discloses a machining method for pre-vulcanizing a lining layer of an all-steel tire by utilizing electron beams. The machining method comprises the specific process that a lining layer rubber sheet production line is started, and lining layer rubber sheets are made to move to a pre-vulcanizing device; when the lining layer rubber sheets enter the pre-vulcanizing device, a device is started; when voltage starts to be boosted to reach 500 KV and keeps stable, the device emits electron beams to irradiate the lining layer rubber sheets, and components are marked; when the irradiation dose on a displayer of the pre-vulcanizing device reaches 40 KGy, the components are marked, and the lining layer rubber sheets begin to be compounded; the irradiated pre-vulcanized lining layer rubber sheets continue moving until leaving the pre-vulcanizing device, and then pre-vulcanization is ended. The machining method has the advantages that due to irradiation on the lining layer rubber sheets through the high-speed electron beams, the performance of rubber can be effectively improved, the mechanical strength of the rubber is remarkably improved, and the uniformity of the tire can be improved; in this way, the thickness of the components can be appropriately reduced, the material consumption can be reduced, and the manufacturing cost can be reduced.

Description

technical field [0001] The invention relates to a tire processing method, in particular to a processing method of an electron beam prevulcanized all-steel tire inner liner. Background technique [0002] Tires are annular elastic rubber products that roll on the ground and are assembled on various vehicles or machinery. Usually installed on the metal rim, it can support the body, buffer the external impact, realize the contact with the road surface and ensure the driving performance of the vehicle. Tires are often used under complex and harsh conditions. They are subjected to various deformations, loads, forces and high and low temperature effects during driving. Therefore, they have high performance requirements in all aspects to ensure the safety of vehicles during driving. performance. [0003] In the traditional process, thermal vulcanization is used to process the tire inner liner film. The traditional thermal vulcanization forms polysulfide bonds, which makes the ...

Problems solved by technology

[0003] In the traditional process, thermal vulcanization is used to process the rubber of the tire inner liner. The traditional thermal vulcanization forms polysulfide bonds, which makes the performance of the rubber poor in all aspects; Influenced by thermal conductivity, there are differences in vulcanization of tire components and uneven vulcanization, which leads to the need to thicken tires to make up for defects and waste materials; sulfur volatilizes during processing, and sulfide overflows in waste treatment, resulting in a large amount of pollution and affecting the environment
