Abstract

The present invention discloses a prescription of an adhesive used for an aircraft tire retreading. The adhesive considers caoutchouc as the main material and also contains the main auxiliary materials of styrene butadiene rubber, adhesion promoter, adhesive, high abrasion furnace black, high dispersion white carbon black, ketoamine age inhibitor, indiscerptible sulfur and sulfenamide accelerant. The main material and the main auxiliary materials are made into gross rubber according to certain weight portion ratio, and the gross rubber is mixed with gasoline by certain proportion to be made into the adhesive. The adhesive of the prescription has the advantage that the adhesive solves the problem of sticking an old tire body with a retreading component when the aircraft tire is retreaded, which ensures that the aircraft tire does not have the problem of the delamination of the glue material between the old tire body and the retreading component, bulging and other quality problems during the use course, and the tire is safe for using.

Description

Technical field: [0001] The present invention relates to a polymer compound, in particular to the formulation of an adhesive used for retreading of aviation tires. Background technique: [0002] Aviation tires are used under the conditions of high speed, high load, instantaneous large impact force and large deformation. The requirement for retreaded aviation tires is to have safety under high load and high speed. When retreading aviation tires, an adhesive should be sprayed on the surface of the old tire after grinding to bond the old carcass and the retreaded parts together. The adhesive strength currently used is not enough, delamination, bulging and other quality problems will occur between the old aviation tire carcass and the retreaded parts after retreading, which will affect flight safety, especially when it can be used with nylon / aramid composite cord skeleton materials The bonding adhesive is still blank, and the nylon / aramid composite cord is a new type of skeleto...
