| titleOfInvention | Amphoteric polymer chrome-free tanning agent and preparation method thereof |
| abstract | The invention discloses an amphoteric polymer chrome-free tanning agent and a preparation method thereof, wherein the preparation method comprises the following steps: in N 2 Under the protection of the method, undecenal, acrylic acid and dimethyl diallyl ammonium chloride are added with an initiator of azobisisobutyronitrile at a certain temperature, and the amphoteric polymer retanning agent is obtained by random copolymerization in an ethanol solution. The amphoteric polymer chrome-free tanning agent provided by the invention contains aldehyde groups, cationic groups, carboxyl groups and aldehyde groups, can effectively improve the reactivity with tanned leather blanks, improves the humidity and heat resistance stability of leather, and improves the matching property with a subsequent wet finishing material. The amphoteric polymer chrome-free tanning agent has relatively large molecular mass and can play a role in filling. |
