| titleOfInvention | Production process and production device of phosphorus-free high-polymer Maran |
| abstract | The invention discloses a production process and a production device of phosphorus-free high polymer Marthird, and the technical scheme is as follows: the production process of the phosphorus-free high polymer Marthird comprises the following steps: s1, selecting materials for standby: the following components were selected for use: acrylic acid and water; the initiator comprises sodium persulfate, ammonium persulfate and hydrogen peroxide; molecular weight regulators including sodium bisulfite, allyl alcohol, sodium metabisulfite; s2, putting a certain amount of water and allyl alcohol into the reaction kettle, and adding sodium bisulfite accounting for 3-10% of the total raw material mass; s3, adding acrylic acid and allyl alcohol in a certain molar ratio into a head tank, heating the reaction kettle to 60-95 ℃, then dropwise adding an initiator accounting for 5-15% of the total raw material mass, sodium metabisulfite accounting for 5-10% of the total raw material mass and acrylic acid, and carrying out polymerization reaction for 4-6 h. The production device of the phosphorus-free high polymer Marthird is provided with the elevated tank, can conveniently carry out production, and has high reaction rate and few production steps. |
