Abstract

The invention provides a coating-type binder used for bonding natural rubber and a metallic 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 cobalt boracyl 23 and cobalt neocaprate, the rubber is natural rubber, the auxiliary agent consists of an age resister, a plasticizer, a filling agent, a strengthening agent, an accelerator, an activator, a silane coupling agent and a vulcanizing agent which are of conventional use in rubber product production. The composite binder is dispersed in rubber material and coordinates with the age resister, the plasticizer, the filling agent, the strengthening agent, the accelerator, the activator, the silane coupling agent and the vulcanizing agent to form a bonding master batch, and the bonding master batch is dissolved by solvent of oil to prepare a mucilage, thus the coating-type binder used for bonding natural rubber and metallic framework is obtained. The coating-type binder used for bonding natural rubber and metallic framework 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 for bonding natural rubber and metal framework for bonding natural rubber including natural rubber and general-purpose synthetic rubber mixed rubber with copper, zinc, copper alloy, zinc alloy and aluminum alloy framework. Coating adhesive and preparation method. Background technique [0002] When existing natural rubber products involve natural rubber and its mixed rubber with general-purpose synthetic rubber and copper, zinc, copper alloy, zinc alloy, and aluminum alloy framework materials for coating and bonding, the bonding method mainly adopts imported coatings mainly based on physical bonding. Cover-type adhesives cannot meet the current production needs of natural rubber products due to the defects of aging resistance, especially heat aging resistance and damp heat aging resistance, and poor dynamic mechanical properties of such adhesives. At present, in the continuous pro...
