| description | The invention relates to the field of high polymer materials and provides an all-water foaming B1-level flame-retardant polyurethane foam insulation material. The material comprises premixed polyetherpolyol and isocyanate, wherein the premixed polyether polyol comprises polyalcohol, a flame retardant, a fire retardant chemical, an emulsifier, a foaming agent, a catalyst and an anti-precipitationagent; the polyalcohol is specifically low-polyphosphoester diol etherified amino resin polyalcohol, and accounts for 15-25% of the premixed polyether polyol; and the anti-precipitation agent is specifically white carbon black, and accounts for 2-3% of the premixed polyether polyol. The invention also provides a preparation method of the all-water foaming B1-level flame-retardant polyurethane foaminsulation material. The all-water foaming B1-level flame-retardant polyurethane foam insulation material disclosed by the invention has the following advantages: a flame-retardant system is formed by phosphorus-containing and |
