Add the emulsifier to the reaction vessel, stir and sequentially add 20kg acrylic acid, 50kg methyl acrylate, and 30kg hydroxymethylacrylamide methyl ether, and heat for emulsification. Then 1.5kg sodium pyrosulfite and 1.5kg potassium persulfate are added to the above lotion, heated to 40~50 ℃ for lotion polymerization. Finally, adjust the pH value to 4 with ammonia water, and control the solid content of lotion to 38%. Prepare leather finishing agents for different purposes according to different formulas.
