Description

Technical Field

[0001] The invention relates to the technical field of tire preparation, and in particular to a method for manufacturing an inner liner to increase film lamination. Background Art

[0002] The skeleton material of all-steel radial tires is made entirely of steel wire. In order to prevent air and water from penetrating and causing the steel wire to rust and delamination, the inner liner must have good air tightness. To ensure sufficient air tightness, the airtight layer rubber material uses halogenated butyl rubber, but halogenated butyl rubber has poor mutual adhesion with other rubber materials, and bubbles are easily generated during the production process. If the inner liner is compounded with two layers (transition layer and airtight layer) of very wide rubber, it is easier to get bubbles when laminating, and the bubbles are not easy to be discharged during vulcanization, resulting in bubbles between the layers of the finished tire and waste products.

[0003] The existing inner liner includes an airtight layer and a transition layer. After the inner liner is laminated on the laminating drum, the nylon cover, the steel wire cover and the carcass are directly laminated. The outer ends of the steel wire cover and the nylon cover are provided with rubber sheets on the sidewall and the rubber core to enhance the adhesion, while the inner ends of the steel wire cover and the nylon cover are directly laminated to the inner liner without any parts to enhance the adhesion. Therefore, it is necessary to enhance the adhesion between the inner liner and the cord layer, and to play a transition buffer role between the inner liner and the relatively rigid cord layer to reduce the shear stress in this area.

[0039] It can be understood that in the above embodiments, in order to avoid the occurrence of air bubbles in the inner liner layer caused by the cylinder pressure of the compound roller press, which may affect the quality of the inner liner layer, when selecting sponge rollers with different hardness levels to control the laminating quality, the cylinder air pressure is controlled between 0.2 and 0.4 MPa.

[0040] In some embodiments of the present application, both the inner liner layer and the carcass ply are irradiated.

[0041] It can be understood that during the tire forming and vulcanizing processes, the carcass ply may experience phenomena such as cord deviation or uneven cord density. The tire inner liner layer (mainly the airtight layer) is a thin pure rubber sheet, and during the vulcanization process, it is more likely to have rubber compound flow, resulting in uneven thickness. To eliminate these drawbacks and improve the tire quality, an electron beam irradiation system can be used to irradiate the rubberized cord fabric and the inner liner layer. Therefore, the irradiation treatment in the above embodiments can significantly improve the quality of the inner liner layer and the carcass ply.

[0042] In some embodiments of the present application, the carcass ply includes a nylon wrapper and a steel wire wrapper. The nylon wrapper is laminated with the steel wire wrapper, and the nylon wrapper is laminated with the rubber sheet.

[0043] It can be understood that in the above embodiments, laminating the nylon wrapper with the rubber sheet can enhance the adhesion between the inner liner layer and the carcass ply, play a transitional buffering role between the inner liner layer and the relatively rigid carcass ply, reduce the shear stress at this part, and effectively reduce the telescopic deformation in the tire flexure area when the tire is running at high load.

[0044] In summary, the present invention discloses a manufacturing method for increasing the lamination of the inner liner with a rubber sheet, which can enhance the adhesion between the inner liner layer and the carcass ply, play a transitional buffering role between the inner liner layer and the relatively rigid carcass ply, reduce the shear stress at this part, and effectively reduce the telescopic deformation in the tire flexure area when the tire is running at high load; by adjusting the working parameters of the extruder and the compound roller press, the probability of air bubbles in the inner liner layer is reduced, avoiding waste of resources; by transforming the existing inner liner production line and adding rubber sheet laminating equipment, automatic rubber sheet lamination can be achieved, saving cost investment.
