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.
Description
Skill wood field
The present invention relates to the preparation method of a kind of leather finish with the modified casein element.
Background technology
In order to guarantee the natural performance of leatherware, be rich in comfort feel and aesthetic feeling again, so in the leather production and the course of processing, often use hide finishes to achieve the above object.And the lactic casein coating and decorating material occupies an important position in surface daub on a wall.The lactic casein coating and decorating material has coating light, high temperature resistant pressing and advantage such as suitable polishing, but the lactic casein coating and decorating material exists hard, the no expandability of film forming, easy fracture again, moisture-proof is wiped, surface adhesion is not firm and cold short shortcoming such as hot sticky.
Summary of the invention
For addressing the above problem, the present invention proposes the preparation method of a kind of leather finish with the modified casein element.
For guaranteeing to reach the designed effect of the present invention, conveniently use, the preparation method of GR-modified casein element of the present invention should be by following its preparation process.
