| titleOfInvention | The preparation method and its product of a kind of high-efficiency coarse whiting ground dispersant of comb shaped structure and application |
| abstract | The invention discloses a kind of preparation methods of the high-efficiency coarse whiting ground dispersant of comb shaped structure, include the following steps: that vinyl carboxylic acid monomer, methacrylic acid polyalkylene glycol monomer, more monothioester chain-transferring agents, initiator is added in (1) in a solvent, and it is bubbled certain time with nitrogen, it seals later；(2) it is heated to certain temperature reaction a period of time；(3) solvent is distilled off after reaction, is diluted with water；(4) pH for adding one or more kinds of base reagent solution regulation systems is 5~8, and adding water to adjust solid content to mass fraction is 20%~50%, can be obtained high-efficiency coarse whiting ground dispersant；Also disclose the pectinate texture dispersing agent prepared using the above method, its side chain effectively enhances steric hindrance, molecular weight and molecualr weight distribution controllable precise, do not introduce free counterion, operation is simple, the method introduces alkali calcium hydroxide/magnesium hydroxide in neutralization stage simultaneously, reduces the counterion effect of dispersing agent, to improve dispersion performance. |
