Rubber cement for static balance patching of aircraft tire

Abstract

The invention discloses a rubber cement for the static balance patching of an aircraft tire. The rubber cement comprises a main material natural rubber, and main auxiliary materials comprising styrene butadiene rubber, an adhesive SL-3090, an adhesive A, a high-dispersivity white carbon black, a silane coupling agent, high-wear-resistance carbon black, an antioxidant BLE, a tackifying resin TKM-M, insoluble sulfur, a sulfonamide promoter and a thiuram promoter. The rubber cement is prepared through mixing by an open mixing machine or a closed mixing machine to prepare a gross rubber, and mixing the gross rubber with a solution gasoline according to a weight ratio of 1:2-5. The adhesive strength between a static balance patch using the rubber cement and the tire liner of the tire is high, so the shedding of the static balance patch is difficult during the use of the tire. The rubber cement has the advantages of high tensile strength and tear tensile, good thermal ageing resistance, fast vulcanization speed, no use of toxic materials comprising polyisocyanate or toluene, and protection of the health of operators.

Description

technical field [0001] The invention relates to a polymer material, in particular to a mortar glue for a static balance patch of an aviation tire. Background technique [0002] The static balance performance of the tire will have an impact on the performance of the tire. If the static balance difference is too large, it will cause the aviation tires to vibrate when they are in use, endangering the safety of aircraft take-off and landing. With the development of the aviation industry, the requirements for aviation tires are getting higher and higher, the speed is higher and the load is larger. The bonding strength between the tire and the tire tire is reduced, and the problem of the subsidized static balance piece in the tire is prone to fall off, so that the static balance difference of the tire is too large, which affects the safety of aircraft take-off and landing. In addition, there is a problem that the existing glue for static balance patches uses toxic materials such...

If the static balance difference is too large, it will cause the aviation tires to vibrate and endanger the safety of the aircraft take-off and landing

With the development of the aviation industry, the requirements for aviation tires are getting higher and higher, the speed is higher and the load is larger. The bonding strength between the tire and the tire is reduced, and the static balance sheet subsidized in the tire is prone to fall off, so that the static balance difference of the tire is too large, which affects the safety of the aircraft take-off and landing

In addition, the existing glue for static balance patches has the problem of using toxic materials such as lechna and toluene, which endanger the health of operators
