Coating-type binder used for bounding nitrile butadiene rubber and metal framework and preparation method

Abstract

The invention provides a coating-type binder used for bounding nitrile butadiene rubber and a metal framework and a preparation method. The 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 and vanadium; the rubber is nitrile butadiene rubber; the auxiliary agent consists of an age resister, a plasticizer, a strengthening agent, a loading 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 loading 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 of the invention. The coating-type binder of the invention not only maintains various excellent properties of the primary direct adding type cobalt salt binder such as high strength bonding, ageing resistance and the like, but also can be used in a coating way like imported coating binder product, thereby having obvious using effect.

Description

technical field [0001] The invention relates to an adhesive, in particular to a coating-type adhesive used for bonding nitrile rubber with copper, zinc, copper alloy, zinc alloy, and aluminum alloy skeletons and a metal skeleton for bonding and a preparation method thereof. Background technique [0002] When the existing nitrile rubber products involve nitrile rubber and copper, zinc, copper alloy, zinc alloy, and aluminum alloy framework materials for coating-type bonding, the bonding method mainly uses imported coating-type adhesives mainly based on physical bonding. This type of adhesive has the defects of aging resistance, especially heat aging resistance and damp heat aging resistance, and poor dynamic mechanical properties, which cannot meet the current production needs of nitrile rubber products. At present, 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,...

AI Technical Summary

Problems solved by technology

[0003] The technical problem to be solved by the present invention is that the existing cobalt salt adhesives are not suitable for coating production process and have higher requirements on the skeleton material for bonding, while the current rubber-metal adhesives that can be coated have resistance Aging, especially poor heat aging r
