Coating-type binder used for bonding ethylene propylene diene rubber and metal framework and preparation method

Abstract

The invention discloses a coating-type binder used for bonding ethylene propylene diene rubber and a metal 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 and calcium; the rubber is ethylene propylene diene rubber and natural 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 ethylene propylene diene rubber and metal framework. The coating-type binder of the invention is suitable for the high tenacity bonding between the mixed rubber of ethylene propylene diene rubber and natural rubber and copper, zinc, copper alloy, zinc alloy and aluminum alloy framework.

Description

technical field [0001] The invention relates to an adhesive, in particular to an EPDM compound used for bonding EPDM rubber, including EPDM rubber and natural rubber, to copper, zinc, copper alloy, zinc alloy, and aluminum alloy skeletons. Coating-type adhesive for bonding propylene rubber and metal skeleton and preparation method thereof. Background technique [0002] Existing EPDM rubber products involve EPDM rubber including its mixture with natural rubber. Bonding of rubber with copper, zinc, copper alloy, zinc alloy, and aluminum alloy skeleton materials mainly adopts imported coating type mainly based on physical bonding. Adhesives, because such adhesives have the defects of aging resistance, especially heat aging resistance and damp heat aging, and poor dynamic mechanical properties, cannot meet the production needs of EPDM products at present. At present, in the continuous production of large-scale rubber product industries such as steel radial tires, steel wire rei...

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 the coating production process and have higher requirements for the skeleton material for bonding, while the rubber-metal adhesives that can be coated currently have aging Especially in the situation of thermal aging and poor dynamic mechanical properties, complex and troublesome bonding operation, high cost of use and environmental pollution of adhesive solvents, a direct-adding cobalt salt adhesive is provided as the basis, combined with appropriate adhesive promoters, through modification.
