Problems solved by technology

[0003] At present, the odor suppression of tires is mostly achieved by adding substances that emit aromatic odors into the tires to improve the tire odor. However, these added substances that emit aromatic odors have a limited time to emit odors, and are extremely susceptible to the impact of tire processing technology. Does not reduce the emission of odor from the source

Abstract

The invention relates to a spare wheel with low smell for passenger cars, and belongs to the field of tires. A rubber material with low smell is used, and the emission degree of the tire smell can bereduced in multiple aspects of tire tread, tire sidewall, tire bead protective rubber, air impervious layer and the like, so that the emission evaluation of the overall smell of a tire meets the requirements. The spare wheel with low smell for passenger cars comprises a tread with low smell, and / or a tire sidewall with low smell, and / or a tire bead with low smell, and / or an air impervious layer with low smell. The tire tread with low smell is prepared from a tire tread rubber composition with low smell, wherein the tire tread rubber composition with low smell is prepared from 100 parts by weight of matrix rubber, and an auxiliary component by weight, and the matrix rubber consists of 60-75 parts of odorless polyisoprene rubber or odorless full latex, and 25-40 parts of high-cis polybutadiene rubber.

Description

technical field [0001] The invention relates to the field of tires, in particular to a passenger car spare tire with low odor emission. Background technique [0002] Due to the addition of a variety of raw materials in the tire production process, some materials have volatile odors themselves, and some produce odorous gases due to chemical reactions during the tire vulcanization process (traditional vulcanization systems produce ammonia gas), such as tires used The raw materials directly or indirectly produce pentaphenyltrialdehyde and other volatile organic compounds, causing odor emission. The main components that affect the emission of tire odor are tread, sidewall, rim protection rubber and airtight layer. Especially for passenger car spare tires, which are usually stored in the compartment, the volatile substances in the tires will produce unpleasant smells. [0003] At present, the odor suppression of tires is mostly achieved by adding substances that emit aromatic o...
