The key technology in the production of steel cord conveyor belt is the adhesion between galvanized steel cord and rubber. The adhesive performance has a direct impact on the service life of the steel cord conveyor belt. The influence of the rubber compounding system on the adhesive properties was studied. The optimized formula of adhesive is natural rubber 30, styrene butadiene rubber 70, nano zinc oxide 4, stearic acid 1, magnesia 4, accelerator NS 2, sulfur 2, silica 15, carbon blackN 330 40, pine tar 7, 70# chlorinated paraffin 20, antioxidant BLE 2, antioxidant RD 1.5, cobalt boroacylate 2, adhesive A 2.
