The present disclosure relates to the technical field of adhesion property improvement, particularly to a process and device for improvement treatment of a polyester cord and a rubber adhesive. By filling an extremely few amount of calcined gypsum powders into chloroprene rubber to be secondarily stirred and extruded while adding fatty acid calcium and an anti-aging agent and uniformly mixing a stirring and mixing component using a specific solvent, the adhesion behavior between the rubber adhesive and the polyester cord is increased, and the bonding strength between the rubber adhesive and the polyester cord is improved; furthermore, through mutual connection and installation of the extrusion modification component, stirring and mixing component and the compounding modification component, continuous operation of modification treatment of the polyester cord and the rubber adhesive, the structure is simple, and use is convenient. .

Contact adhesive compositions comprising polychloroprene and, based on the polychloroprene content, 10 to 99 wt % of ethylene-vinyl acetate copolymer exhibit outstanding adhesion to substrates such as ethylene-vinyl acetate copolymers, thermoplastic elastomers or flexible PVC. The contact adhesive compositions of the invention are especially suitable for use in the bonding of articles, preferably articles in which at least part of the articles to be bonded consists of polyurethane, flexible PVC, ethylene-vinyl acetate copolymers and/or thermoplastic elastomers. This allows the adhesive composition to be employed widely in the footwear industry, for the bonding of roofing membranes containing flexible PVC, ethylene-propylene-diene rubber (EPDM) and/or ethylene-vinyl acetate copolymers, or for the bonding of synthetic leather based on flexible PVC.
