Abstract

The invention relates to the application field of the tire industry, in particular to a mixing method for improving the odor of a tire and reducing VOC of a rubber compound, the rubber compound and the tire. The odor properties of vulcanized rubber and tires are improved through a mixing process, a large part of small-molecule odor substances generated in the mixing process have volatility, a top peg is lifted up to open a charging door in a high-temperature section in the production process to keep production, and part of odor substances can be discharged, so that the purposes of improving the odor properties of rubber materials and reducing voc of the rubber compound are achieved; when the odor-improved rubber material is used for producing a tire, the odor of the tire can also be improved.

Description

technical field [0001] The invention relates to the application field of the tire industry, in particular to a mixing method for improving the tire odor and reducing the VOC of the mixed rubber, the mixed rubber and the tire. Background technique [0002] With the improvement of people's quality of life, people's requirements for ride safety and comfort are getting higher and higher, and the odor of tires (especially spare tires) seriously affects people's ride experience. Automobile manufacturers have increasingly stringent requirements on the odor of tire products and tire VOC content. Therefore, tire manufacturers attach great importance to how to reduce tire odor and reduce tire VOC content. The main odor and VOC sources of tires are various raw rubber, sparser and chemical additives. The pyrolysis of raw materials and the mutual reaction of additives produce low molecular weight, and volatile ones such as amines, cyclohexanone, phenol, and benzothiazole have pungent od...
