Abstract
The invention discloses a steel wire protective layer repair adhesive for retreading a radial aircraft tire and application of the steel wire protective layer repair adhesive. The steel wire protective layer repair adhesive is prepared by taking natural rubber as a main material, taking styrene-butadiene rubber, an adhesive, cobalt boroacylate, phenolic resin, high-dispersion white carbon black, a silane coupling agent, carbon black with high wear resistance, a ketone amine type anti-aging agent, insoluble sulfur and a sulfonamide type accelerator as main auxiliary materials, and mixing by an open mill or an internal mixer. The application is that a rubber compound is mixed with a solvent, namely gasoline according to the mixture ratio of 1: (3-6) to prepare adhesive cement of the repair adhesive, and the rubber compound is additionally pressed into a slice on a tabletting machine and cut into a certain size to form a rubber piece which is used as the rubber piece of the repair adhesive. The adhesive has the advantages of relatively high tensile strength, tear strength and stress at definite elongation, good resistance to thermal aging and low dynamic heat production; furthermore, the adhesive has good adhesion performance with a steel wire, and the adhesion performance of the adhesive after thermal aging with the steel wire is not reduced significantly.
Description
Technical field
The present invention relates to meridian aviation tyre, specifically a kind of steel wire cover repair sheets and application thereof of renovating meridian aviation tyre.
Background technology
Aircraft tyre is one of vitals of Aircraft landing gear system, and its effect is the weight of support aircraft and takes off, lands and slide.It is economize on resources and reduce the usual way that airline runs cost that aircraft tyre carries out recycle by renovation.Along with the development of aircraft industry, meridian aviation tyre commercially occupy continuous increase, the renovation of meridian aviation tyre becomes inexorable trend.
Generally for the belt of protection meridian aviation tyre, the Tire production chamber of commerce is at outer setting one deck of the belt of meridian aviation tyre or two-layer protective layer, and the framework material that its protective layer uses is generally steel wire or aramid fiber.
The old carcass that the meridian aviation tyre being designed with steel wire cover need renovate, wears up to steel wire cover mostly all, and steel wire is exposed and may wear and tear and get rusty.Belt due to meridian aviation tyre is key part, when so not changing protective layer when renovating, then special sizing material must be used to repair protective layer.Solve the adhesion problem of sizing material and exposed steel wire, guarantee the realization again of steel wire protection layer function.The shortcoming of carrying out steel wire cover repairing with the sizing material of existing renovation aircraft tyre and rubber cement thereof is: due to the exposed position copper plate of meridian aviation tyre steel wire cover; may all or locally be worn away; on the bonding of rubber and steel wire, there is bad impact, and the sizing compound formula of existing renovation aircraft tyre is not optimized for the bonding of rubber and steel wire.So that rubber strength is lower, the bond strength of rubber and steel wire is lower, and heat aging property is poor.These shortcomings may cause the meridian aviation tyre of renovation in use, easily because the bad initiation of steel wire cover local bond is come to nothing, got rid of the faults such as tyre surface.
Summary of the invention
The object of the invention is, for solving the deficiency of the sizing material of existing renovation aircraft tyre, and provide a kind of steel wire cover repair sheets and application thereof of renovating meridian aviation tyre, the renovation for meridian aviation tyre provides effective technical guarantee.
realizing technical scheme of the present invention is:
Renovate steel wire cover repair sheets for meridian aviation tyre, be by following raw material and materials weight by mill or mixer mixing, make rubber unvulcanizate:
