Abstract:
      The effect of main components in phenolic resin/chloroprene rubber adhesive（hereinafter referred to as phenolic/chloroprene adhesive） on the bonding performance between 45# steel and natural rubber（NR） was studied through the orthogonal experiment，and the optimal combination of the factor and level was determined through range analysis and verified by experiments.The results showed that the silica content，coupling agent type and phenolic resin content in phenolic/chloroprene adhesive were the main factors affecting the bonding performance between 45# steel and NR.The optimal combination of main components of the adhesive was 4 phr silica，80 phr phenolic resin，20 phr chlorinated NR and 8 phr coupling agent KH550.Under the optimizied combination，the heat resistance and film water resistance of the adhesive were good.The tensile shear strength of 45# steel and NR adhesive could reach 4.57 MPa.
