Abstract

The invention discloses a steel wire protective layer repair adhesive for retreading a radial aircraft tire and application of the steel wire protective layer repair adhesive. The steel wire protective layer repair adhesive is prepared by taking natural rubber as a main material, taking styrene-butadiene rubber, an adhesive, cobalt boroacylate, phenolic resin, high-dispersion white carbon black, a silane coupling agent, carbon black with high wear resistance, a ketone amine type anti-aging agent, insoluble sulfur and a sulfonamide type accelerator as main auxiliary materials, and mixing by an open mill or an internal mixer. The application is that a rubber compound is mixed with a solvent, namely gasoline according to the mixture ratio of 1: (3-6) to prepare adhesive cement of the repair adhesive, and the rubber compound is additionally pressed into a slice on a tabletting machine and cut into a certain size to form a rubber piece which is used as the rubber piece of the repair adhesive. The adhesive has the advantages of relatively high tensile strength, tear strength and stress at definite elongation, good resistance to thermal aging and low dynamic heat production; furthermore, the adhesive has good adhesion performance with a steel wire, and the adhesion performance of the adhesive after thermal aging with the steel wire is not reduced significantly.

Description

technical field

[0001] The invention relates to a radial aviation tire, in particular to a steel wire protective layer repair glue for retreading a radial aviation tire and an application thereof. Background technique

[0002] Aviation tires are one of the important parts of the aircraft landing gear system. Its function is to support the weight of the aircraft and take off, land and taxi. Recycling aircraft tires through retreading is a common practice to conserve resources and reduce airline operating costs. With the development of the aviation industry, the market share of radial aviation tires continues to increase, and the retreading of radial aviation tires has become an inevitable trend.

[0003] Usually, in order to protect the belt layer of the radial aircraft tire, the tire manufacturer will arrange one or two layers of protective layer on the outside of the belt layer of the radial aircraft tire, and the skeleton material used in the protective layer is generally...
