Problems solved by technology

This kind of rubber compound generally exposes a series of problems such as easy aging, low heat resistance, weak pressure retention, and short life, which affect the use of aviation tires.
[0003] Halogenated (brominated or chlorinated) butyl rubber is a kind of rubber with good stability. It has the characteristics of superior ozone resistance, weather resistance, temperature resistance and good air tightness. Increasing its dosage can improve the resistance of the rubber compound. Air permeability, but for tires or aircrafts that require high pressure-holding performance, there is still a certain gap in the pressure-holding performance only by increasing the amount of halogenated butyl rubber, and it is necessary to find ways to improve it from fillers

Abstract

The invention discloses a graphene-containing aircraft tire sealing layer rubber material and a preparation method thereof. The rubber material comprises the following raw materials by weight: 50-100parts of halogenated butyl rubber, 0-50 parts of synthetic rubber, 40-80 parts of a carbon black filler, 1-10 parts of graphene, 10-30 parts of flaky mineral, 0.5-3 parts of an acid absorption agent,4-20 parts of a processing aid, 0-5 parts of an anti-aging agent, 2-5 parts of tackifying resin, 1.5-5 parts of a vulcanizing agent and 1-2.5 parts of a vulcanization accelerator. According to the invention, by adding of graphene and flaky mineral, selection of other material varieties and reasonable formula proportioning, one or more aircraft tire sealing layer rubbers with good physical properties, gas tightness, heat aging resistance and aging cracking resistance can be designed. The rubber material has simple components and easily available raw materials, and is convenient for manufacturing and implementation. When applied to aircraft tires to serve as a sealing layer, the graphene-containing aircraft tire sealing layer rubber material can greatly reduce the permeability of aircraft tire inflation gas, improve the pressure maintaining performance of aircraft tires, and improve the safety and service life of aircraft tires.

Description

technical field [0001] The invention belongs to the field of tire processing, in particular to a graphene-containing aviation tire sealing layer compound and a preparation method thereof. Background technique [0002] At present, most aviation tire sealing layer rubber materials mainly use halogenated butyl rubber together with some natural rubber and styrene-butadiene rubber materials, and N330, N326 and N660 carbon black are mainly used as fillers. This kind of rubber compound generally exposes a series of problems such as easy aging, low heat resistance, weak pressure retention, and short life, which affect the use of aviation tires. [0003] Halogenated (brominated or chlorinated) butyl rubber is a kind of rubber with good stability. It has the characteristics of superior ozone resistance, weather resistance, temperature resistance and good air tightness. Increasing its dosage can improve the resistance of the rubber compound. Breathability, but for tires or aircrafts t...
