Pneumatic tire containing oxygen absorbent

Abstract

A pneumatic tire capable of preventing the durability thereof from being deteriorated by the penetration of the air filled in the tire to the inside of the tire body thereof. A laminate formed by laminating inner liner materials on both surfaces of a rubber or thermoplastic resin composition layer containing an oxygen absorbent is used as an inner liner, a tie rubber, a rubber member interposed between the edge parts of a tire structural material and the inner surface of the tire (namely, the inner liner), or formed in a sheet-like shape and used, as a filling sheet, between the edge parts of the tire structural material and the inner liner.

Description

technical field [0001] The present invention relates to a pneumatic tire using a rubber and / or thermoplastic resin composition containing an aerobic absorbent, and more specifically, to a pneumatic tire using a rubber or thermoplastic resin composition containing an aerobic absorbent as a rubber component Pneumatic tires. Background technique [0002] In a pneumatic tire, since ordinary air is filled in the inner space of the tire, there is a problem that the oxygen contained in the filled air permeates into the inside of the components constituting the tire, oxidatively attacking each part of the tire over time, and affecting the inflation rate. affect the durability of the tire. In order to solve this problem, people have carried out various researches all the time, for example proposed the following scheme: filling nitrogen gas instead of air (refer to Japanese Patent Application Laid-Open No. 10-250311), remove oxygen from internal gas (refer to Patent Publication No. 2...

Problems solved by technology

[0002] In a pneumatic tire, since ordinary air is filled in the inner space of the tire, there is a problem that the oxygen contained in the filled air permeates into the inside of the components constituting the tire, oxidatively attacking each part of the tire over time, and affecting the inflation rate. impact on tire durability

In order to solve this problem, people have carried out various researches all the time, for example proposed the following scheme: filling nitrogen gas instead of air (refer to Japanese Patent Application Laid-Open No. 10-250311), remove oxygen from internal gas (refer to Patent Publication No. 2002-337507 Publication), the method of providing a cord auxiliary layer to escape to the outside (refer to Japanese Patent Laid-Open No. 2003-80905), but there is a problem that nitrogen filling is expensive and burdens use, and moisture intrusion from the outside deteriorates the durability. , it is not yet practical
