Coating-type binder used for bonding natural rubber and bare steel framework and preparation method

Abstract

The invention provides a coating-type binder used for bonding natural rubber and a bare steel framework and a preparation method. The coating-type binder is prepared from a composite binder, rubber and an auxiliary agent, wherein the composite binder consists of a main binder and an auxiliary binder which become A component, the main binder consists of cobalt boracyl 23 and cobalt neocaprate and the auxiliary binder is a composite organic salt containing nickel, vanadium and calcium; the rubber is the mixed rubber of natural rubber, styrene-butadiene rubber and cis-butadiene rubber; the auxiliary agent consists of an age resister, a plasticizer, a strengthening agent, an accelerator, a activator and a vulcanizing agent which are of conventional use in rubber product production, A component is dispersed in rubber material and coordinates with the age resister, the plasticizer, the strengthening agent, the accelerator, the activator and the vulcanizing agent to constitute binding master batch B; the binding master batch B is dissolved by solvent of oil to prepare the coating-type binder used for bonding natural rubber and bare steel framework. The coating-type binder of the invention can be used in middle-size and small-size rubber product industry, and can also be used on the refurbishment of radial ply tires of steel wires and the production of rubber products such as steel wire reinforcement traveling belt joint glue filling.

Description

technical field [0001] The present invention relates to an adhesive, in particular to a coating-type adhesive for bonding natural rubber, general-purpose synthetic rubber and its mixed rubber with carbon steel bare steel skeleton materials for high-strength bonding and its preparation method. Background technique [0002] In the continuous production of large-scale rubber products such as steel radial tires, steel wire reinforced conveyor belts, and steel wire braided rubber hoses, it is necessary to perform high-strength bonding of elastomers such as rubber and galvanized or brass-plated steel cord braided skeleton materials. In order to effectively ensure the high-strength adhesion between rubber and this type of metal framework, and to have high anti-aging, heat and oxygen resistance, heat and humidity resistance, and salt water corrosion resistance, the existing technology usually uses a direct-addition cobalt salt adhesive. Add organic acid cobalt salts such as cobalt ...

AI Technical Summary

Problems solved by technology

[0004] The technical problem to be solved by the present invention is that the existing cobalt salt adhesives are not suitable for the coating production process and cannot be used for bonding with carbon steel bare steel skeleton materials, while the currently used coating adhesives have Aging and heat aging and poor dynamic mechanical properties, complex and troublesome bonding operations, high cost of use, and environmental pollution from adhesive solvents, provide a direct-added cobalt salt adhesive based on appropriate adhesive promoters, through the improvement Coating-type adhesive for bonding natural rubber and bare steel framework suitable for coating production process and preparation method
