preparation of AKD resin stearic acid chloride is added to the reaction kettle, then 0.3% triethyl phosphate is added as catalyst and tertiary amine is used as polymerization inhibitor. Cracked at 570~780 ℃ to obtain AKD.
Emulsification Mix cationic starch with water and add it to the reactor, adjust the pH value to 3.5 with sulfuric acid. Then gelatinize at 90~95 ℃ for 1 h, cool to 75 ℃ and add AKD under stirring. It is homogenized by a high-pressure homogenizer of 30 MPa, and then diluted with water to form the required emulsion.
