The present invention relates to a kind of full water foamed cold-curing foam fireproof gap-filling glue and preparation method thereof, belong to fire-proof sealing material technical field.Including 100 parts of polyalcohol, 38 50 parts of liquid phosphorus acid esters fire retardant, 110 120 parts of powder fire retardant, 25 parts of pigment, 1.8 4 parts of deionized water, 0.5 1.8 parts of tertiary amine catalyst, 1.8 2.4 parts of the temperature sensitive catalyst of hydrolysis, 1.8 2.5 parts of chain extender, 0.4 0.6 parts of high-activity silicon oil, 2.76 11 parts of catalyst activator, 0.8 1.8 parts of coupling agent；64 169 parts of polyisocyanates.Beneficial effect：With more excellent base material adhesive force, demand that can be in terms of ensureing to take into account environmental protection while lighting；And meet do not possess the onsite application demand of heating condition using the temperature sensitive catalyst of quaternary ammonium salt as the gel catalyst of hydrolysis in the present invention；The foaming layer of formation not only itself has excellent anti-flammability, also occurs that expansion forms solid fine and close carbon-coating concrete on fire occurs, and plays a part of preventing flame skewered from spreading and preventing calorie spread. |
