AI Technical Summary

Technical Problem

The mechanical properties and adhesive properties of existing corrugated protective layer rubber are insufficient to meet the harsh high-speed and high-load operating conditions of civil aviation radial tires.

Method used

1# smoked rubber is used as the main material, and auxiliary materials such as N330 carbon black, N46 engine oil, insoluble sulfur, anti-reversion agent HVA-2, adhesive RS, C9 resin and tackifying resin HT-M are added. Through specific process steps, a corrugated protective layer adhesive with high adhesion, impact resistance, tear resistance, puncture resistance and fatigue resistance is prepared.

Benefits of technology

The adhesive performance and comprehensive performance of the corrugated protective layer adhesive are improved, the production cost is reduced, and the durability and resistance to foreign object puncture of the tire are enhanced.

Abstract

The invention discloses a civil aviation radial tire corrugated protective layer rubber and a preparation method thereof, and the rubber adopts a technical method that 1 # smoked sheet rubber is used as a main body material, N330 carbon black is used as a reinforcing system, N46 engine oil is used as a plasticizer, insoluble sulfur, an accelerant DZ and the like are used as vulcanizing agents, and an adhesive RS, C9 resin and tackifying resin HT-M are used as an adhesive system. The rubber material with high adhesion, impact resistance, tear resistance, puncture resistance, low heat generation and good fatigue resistance is prepared through a certain mixing process, and the rubber material serving as the corrugated protective layer rubber material of the civil aviation radial tire has good adhesion performance of a framework material (aramid fiber rope), higher physical performance, lower heat generation performance and good anti-fatigue performance. The damage resistance of foreign object puncture resistance and mechanical damage resistance of the civil aviation radial tire is improved, so that the durability of the tire is improved.
