| titleOfInvention | Flame-retardant polymer polyol and preparation method and application thereof |
| abstract | The invention provides a flame-retardant polymer polyol, a preparation method and application thereof. The raw materials comprise the following components in parts by weight: 100 parts of high-activity polyether polyol; 8-25 parts of melamine; 8-25 parts of dicyandiamide; 60-80 parts of formaldehyde solution; 3-8 parts of phosphonamide; 10-32 parts of urea; and 2-7.6 of macromolecular stabilizer, which is prepared by adding raw materials comprising acrylic acid/methacrylic acid monomer containing epoxy group, acrylate/methacrylate containing polyether glycol group, alkyl-terminated polyether glycol acrylate/methacrylate and acrylic acid/methacrylic acid monomer containing halogen into a protic solvent containing chain transfer function according to the mass ratio of 1 (5-15) to (15-25) for polymerization. The preparation method comprises the following steps: and adding the other raw materials into the high-activity polyether polyol medium to carry out polycondensation reaction to obtain the flame-retardant polymer polyol. It has high solid content, low viscosity and high stability. The preparation method is simple. |
