The waterborne self matting polyurethane resin was used as the basic resin,defoamer,wetting agent,functional additive,crosslinking agent,cosolvent and other raw materials were added,and the waterborne flexible coating was prepared with plastic as the substrate.The main properties of the resin were investigated,and the effects of the coating system on the wear resistance of the paper tape and the influencing factors of the coating resistance,hand feel and scratch resistance were compared.The results show that the waterborne two-component polyurethane self extinction system has better performance than the single component polyurethane self extinction system,and a good hand feel is obtained by adjusting the formula T-2.
