| titleOfInvention | Preparation method of in-situ polymerization solid dispersant |
| abstract | The invention discloses a preparation method of an in-situ polymerization solid dispersant, which comprises the following steps: premixing a (methyl) acrylate aqueous solution, maleic anhydride, an allyl polyether macromonomer and an initiator aqueous solution; spraying and adsorbing the carrier powder; aging for 2-4 hours; carrying out polymerization reaction; vacuumizing for 0.5-1 hour at 95-100 ℃; cooling to below 40 deg.C, detecting, pulverizing, sieving, and discharging. The preparation method of the invention adopts the process of pre-neutralization and in-situ polymerization, thus solving the problems of uniformity of physical mixing structure of the solid dispersant and difficult dissolution in use; the prepared solid dispersant is a novel solid aqueous dispersant, has the characteristics of environmental protection, safety, excellent dispersion performance, stable storage, convenient transportation and the like, perfects the variety of products in the domestic market, provides a novel dispersant variety for powder auxiliary agent products, and fills the blank of in-situ polymerization solid dispersants. |
