The hyperbranched polyamide ester with large amount of hydroxyl end groups was prepared and then modiifed with silane coupling agent KH560. The product was a hyperbranched interface agent and applied in the treatment of polyester-cotton canvas of flame retardant PVC conveyor belt. The test results showed that the adhesion strength between cover rubber and polyester-cotton canvas was improved by using the interface agent. Typically, the 3rd generation hyperbranched polyamide ester was prepared by using AB2 monomer and trimethylolpropane as the core, at the molar ratio of 21∶1. Correspondingly, the 3rd generation interface agent was obtained by using the 3rd generation hyperbranched polyamide ester and KH560 at the molar ratio of 24∶1. It was found that when the concentration of the 3rd generation interface agent in the treatment was 0.003 mol·L-1, the maximum adhesion strength between cover rubber and polyester-cotton canvas was achieved. The high temperature performance of the belt with the hyperbranched interface agent was excellent and the adhesion strength at 100℃was still able to keep more than 75%. The cost of the hyperbranched interface agent was lower than the silane coupling agent, and the recommended concentration was 2%~2.5%.
