Problems solved by technology

Because of concerns about the safety of employees, most tire manufacturers do not adopt any equipment and technology, and increase the thickness of the rubber material of the airtight layer to ensure the safety factor. Although qualified tires can also be produced, the uniformity of the airtight layer is also reduced. Disadvantages such as waste of raw materials

Embodiment Construction

[0013] As shown in Figure 1, the inner liner sheet is fixed on the non-traction transmission device under the laser 1, and the laser scanning process is performed; the laser is a continuous laser with a power of 500-100 watts and a scanning width of 0.2-1.6 m, the transmission speed of the traction device 2 is 0-40m / min, and the processed tire inner liner parts are made into inner liner inner liner parts.

[0014] The principle of the vulcanization and cross-linking pretreatment inner liner inner liner components and the preparation process of the present invention is to realize uniform pre-vulcanization inside or on the surface by adjusting the energy of the laser. The high-energy laser is focused on the inside or surface of the rubber substrate to activate the rubber macromolecules. Active free radicals are generated, and the mutual combination of these free radicals (coupling termination) makes the rubber macromolecules form a C""C bond, cross-linking occurs, and the rubber ...

Abstract

The invention discloses a new method for crosslinking a tire inner liner rubber material by a laser technology; a tire prepared after the rubber material treated by the method is crosslinked and vulcanized has the advantages of stable inner liner layer forming structure size and performance, the rubber layer thickness is thinned, the adhesion strength is enhanced, the tire weight and energy consumption (lightweighting and energy conservation) are reduced, and the uniformity and dynamic balance of the tire are effectively improved.

Description

technical field [0001] The invention relates to a new method for cross-linking the rubber material of the inner liner of the inner liner of the radial tire by using laser technology. Background technique [0002] In recent years, the rapid development of the rubber industry has provided a broad market space for the tire industry, enabling the tire industry to develop rapidly. The development of tire technology is also developing towards green, lightweight and energy-saving. Relying on technological transformation and technological innovation, new technologies, new processes and new products in tire production continue to emerge, and tire manufacturers have accelerated the pace of moving towards high-tech enterprises. [0003] At present, there are generally two types of tire innerliner crosslinking used in tire production: one is the use of ray radiation crosslinking. In this way, industrial radiation sources mainly include cobalt 60 (γ-rays) and electron beam equipment (e...
