| titleOfInvention | Preparation method and device of high-content acrylic copolymer |
| abstract | The invention provides a preparation method of a high-content acrylic copolymer, which comprises the following steps: s1: putting a mixed solution of an acrylic monomer and an unsaturated monomer containing sulfonic acid in a molar ratio of 1: 1-10: 1 into a reaction kettle, adding sodium bisulfite according to 1-15% of the mass of a monomer raw material, heating to 60-95 ℃, then dropwise adding an initiator of 2-15% of the total mass of the monomer raw material, and carrying out polymerization reaction for 6-8 hours to obtain a light yellow to amber transparent liquid; s2: concentrating the product obtained from the S1 at the temperature of 80-100 ℃ for 6-12 h to obtain a yellowish to amber viscous liquid, wherein the solid content is controlled at 60-80%; s3: and (4) adding a solvent absolute ethyl alcohol into the product obtained in the step (S2), cooling to 40-60 ℃, and continuously stirring for 2-3 hours. The preparation method and the device of the high-content acrylic copolymer provided by the invention can be used for producing the crystalline product of the acrylic copolymer, have the advantages of simple package, reduced storage and transportation energy consumption in flow transfer, easy control of field application and the like, and bring great convenience to product use. |
