Abstract

The invention provides a method for reducing the odor of a pneumatic tire and a low-odor tire. The method comprises the following steps: providing a rubber mixing solution; the rubber mixing solution includes an organic solvent for dissolving rubber and a rubber composition, and the rubber combination The composition includes the following components by weight: 60-100 parts of butyl rubber; 0-40 parts of natural rubber; 30-70 parts of carbon black; 1-10 parts of naphthenic oil; 2-6 parts of oxidized Zinc; 1-3 parts of stearic acid; 2-6 parts of binder resin; 2-6 parts of dispersant; 0.5-2 parts of sulfur; applying the rubber mixture solution to the surface of unvulcanized raw tire , add sulfur to get low-odor tires. The method of the invention can easily and effectively reduce the odor levels of tires with different formulas without changing the existing formulas and manufacturing conditions, which is beneficial to popularization and application.

Description

technical field

[0001] The invention relates to the technical field of pneumatic tires, in particular to a method for reducing the odor of pneumatic tires and low-odor tires. Background technique

[0002] As the government and people's requirements for environmental protection and quality of life increase, the requirements for the manufacture of tires and the level of odor produced by products are becoming increasingly stringent. Therefore, tire manufacturers and manufacturers attach great importance to how to eliminate the odor of tire products. The carcass of the pneumatic tire is mainly made of raw materials such as rubber and chemical additives through mixing and crosslinking. The smell of tires mainly comes from raw rubber, plasticizers and other chemical additives. Among them, low-molecular-weight and volatile substances include amines, ketones, and small-molecule styrene (such as free styrene in styrene-butadiene rubber), etc., whose odor is strong, and when the conc...
