Abstract: The surface of rubber was modified and coated by connection layer and the interfacial binding of vinyl resin composite and rubber was investigated.Results showed that when the rubber surface was treated with chemical reagent, microcracks appeared on the surface, which was beneficial for the binding; when the rubber surface was chemical treated and coated with flexible connection layer, the peel strength of the interface was improved to 2. 90 k N/m and the adhesive strength 2. 30 MPa.
