The development of a waterborne two-component black matt coating is introduced,this paper discusses how to prepare a waterborne two-component black matt coating with environmental protection and fine coating surface from resin,NCO/OH mole ratio,matting agent and slip agent.The results showed that a kind of waterborne low hydroxyl value acrylic resin was synthesized and the waterborne carbon black color paste was prepared,and the waterborne two-component black matt coating was further prepared・When the molar ratio of NCO/OH is 1.2:1.0,the ideal appearance of the film can be obtained by using 3%matting agent TS-100 and 0.75%slip agent P.
