Formula of nylon/aramid fiber composite cord hanging glue for aircraft tire

Abstract

The present invention discloses a prescription of nylon and aramid fibre composite cord coating used for an aircraft tire and is characterized in that glue stock considers caoutchouc as the main material and contains the main auxiliary materials of styrene butadiene rubber, adhesion promoter, high abrasion furnace black, high dispersion white carbon black, silane coupling agent, indiscerptible sulfur and sulfenamide accelerant. The main material and the main auxiliary materials are mixed and milled by an internal mixer according to the certain proportion. The glue stock of the prescription has the advantages that the adhesion strength of the nylon and aramid fibre composite cord with the glue stock of rubber can be improved; the adhesion holding rate after thermal aging is high; a tread bracing layer part does not have the quality problems of glue-cord delamination and the delamination between layers when the glue stock is used under the rigorous using condition with high tensile strength, high tear strength and high load.

Description

Technical field: [0001] The invention relates to a polymer rubber material, in particular to the formulation of nylon / aramid composite cord hanging glue for aviation tires. Background technique: [0002] The skeleton materials used in the production of known aviation tires are mostly nylon cords. With the improvement of aircraft technical indicators, aviation tires are moving toward high speed, high load, light weight, long life, impact resistance, puncture resistance, and safer use. develop. Replacing nylon cords with nylon / aramid composite cords as the skeleton material of aircraft tires is a major breakthrough in aircraft tire manufacturing technology. The nylon / aramid composite cord has been patented separately. However, the aramid fiber in the nylon / aramid composite cord has the disadvantage of not having a high degree of adhesion to the rubber compound. Therefore, a new type of nylon / aramid composite cord with high bonding strength is designed, and the bond remains a...

Problems solved by technology

However, the aramid fiber in the nylon / aramid composite cord has the disadvantage of not having a high degree of adhesion to the rubber compound. Therefore, a new type of nylon / aramid composite cord with high bonding strength is designed, and the bond remains after heat aging. It is very important to have a high rate of hanging glue. At present, nylon / aramid composite cord hanging glue is still blank.
