| titleOfInvention | A kind of preparation method of flame-retardant polyurethane foam containing guanidine phosphate polyether |
| abstract | The invention provides a preparation method of flame-retardant polyurethane foam containing guanidine phosphate polyether, which belongs to the field of polymer materials. The preparation method includes the following steps: (1) under the condition of 20-30°C, take 10-40 parts by weight of guanidine phosphate polyether polyol A, 5-10 parts by weight of guanidine phosphate polyesterol B, and 40-80 parts by weight Polyether polyol C, stir well; (2) at 20-30°C, add 1-5 parts by weight of water, 0.05-3 parts by weight of catalyst, 0.1-3 parts by weight of the material obtained in step (1) in 100 parts by weight 2 parts by weight of foam stabilizer and 0-50 parts by weight of filler, stir well; (3) under the condition of 20-30 ℃, in the mixture obtained in step (2), add 30-70 parts by weight of isocyanate D, and after stirring, Foaming and curing to obtain polyurethane foam. The preparation method of the invention has the advantages of short foaming time, and the prepared flame-retardant polyurethane foam has good flame-retardant performance, high tear strength and low TVOC content. |
