Abstract

The invention discloses a preparation method of modified casein for leather finishing. The preparation method comprises the following steps: adding part of boiled water into a reaction kettle, and adding ammonia water, casein, TX-10 and Turkey red oil; adding part of caprolactam assistant 1 into part of boiled water; adding the rest caprolactam assistant 2 into part of boiled water; adding ammonium persulfate assistant 3 into part of boiled water; adding a formula amount of sodium benzoate assistant 4 into part of boiled water; adding phenol assistant 5 into part of boiled water; adding the assistant 1, the assistant 3 and glycol into the reaction kettle; dripping the assistant 2 into the reaction kettle, and slowly heating; adding the assistant 4, the assistant 5 and glycerol into the reaction kettle; and stirring, and then, discharging. The modified casein prepared by the invention has the advantages of bright coating, high-temperature ironing resistance and the like, is suitable for polishing, and is used for surface finishing of light leather to enable the light leather to have the characteristics of full and soft hand feeling, good elasticity, cold resistance, strong bonding force, good water resistance and the like.
