Abstract

The invention discloses mastic for leather and a preparation method thereof, and aims to provide mastic for leather with water resistance and excellent emulsion adhesive force and scrath resistance as well as the preparation method thereof. The mastic for leather is prepared by ten groups of raw materials; meanwhile, reactive emulsion Emlusogen Aps1080 and Bisomer SEM are adopted to replace anion emulsifying agent and non-ionic emulsifying agent, thereby improving the water resistance of the emulsion; in addition, dipropylene ketol acrylamide and 1, 6- adipic dihydrazide are adopted to solve the problems of poor emulsion adhesive force and poor scrath resistance.
