Abstract

The invention provides a preparation method of a bead ring hanging rubber of full-steel load radial tire. The preparation method comprises the following steps: mixing chlorinated rubber, nitrile rubber, methyl vinyl silicone rubber, coumarone resin, white carbon black, polyhydric alcohols and silicone emulsion for uniform blending, then adding carbon black, sodium polyacrylate and chlorinated polypropylene for uniform blending, then adding a promoter, non-soluble sulfur, hexamethylenetetramine and superfine silica powder for uniform blending and batching out, and finally vulcanizing blended rubber in a press vulcanizer and stewing to obtain the bead ring hanging rubber. The rubber material provided by the invention is high in breaking strength and high in steel wire drawing force, and a finished tire product is high in durability.

Description

technical field [0001] The invention belongs to the technical field of tire production, and in particular relates to a method for preparing all-steel heavy-duty radial tire bead ring glue coating. Background technique [0002] The radialization, tubeless and flattening of tires are the development trend of the current tire industry. More than 90% of the trucks in developed countries and regions such as Europe and the United States are equipped with all-steel radial truck tires; although the radial truck tires in my country started very late, they have developed rapidly. At present, the radialization rate of truck tires in my country has reached 45%. With the rapid development of my country's national economy, the existing car ownership is far from being able to meet the requirements of the growing material flow. In this case, the phenomenon of overloaded transportation inevitably appeared, and it became more and more serious. According to on-site surveys, existing vehicles...
