| titleOfInvention | Water-soluble polymer polyol and preparation method thereof |
| abstract | The invention discloses a water-soluble polymer polyol and a preparation method thereof, wherein the polymer polyol is prepared by the reaction of polyether polyol, styrene, acrylonitrile, hydrophilic group polyether graft, isopropanol and tert-amyl peroxy-2-ethyl hexanoate; the preparation method adopts a one-step method, and has the advantages of simple process, low cost and mild reaction; the hydrophilic group polyether graft has the characteristics of good water solubility and good dispersant property, the viscosity of the product is greatly reduced, the conversion rate of the product is increased from 98.5 percent to 99.0 percent, the amount of residual monomers is reduced, the preparation method is environment-friendly, the solid content of the product is high, the VOC is low, and the quality is more stable; the decomposed products of the tert-amyl peroxy-2-ethylhexanoate are all nontoxic oxygen-containing volatile gases with high purity, and compared with azodiisobutyronitrile, the product conversion rate is 5 per thousand higher and the VOC is low; meanwhile, a molecular removal technology and an oil-free vortex vacuum technology are introduced in the preparation process, the preparation method with the recovery amount of the residual monomers accounting for 5 per mill is environment-friendly, and the VOC is low; in significant contrast to current polymer polyol manufacturing processes. |
