Title: WATER-BLOWN RIGID INORGANIC HYBRID MELAMINE POLYURETHANE FOAM MATERIAL AND PREPARATION METHOD THEREFOR
Abstract:
A water-blown rigid inorganic hybrid melamine polyurethane foam material and a preparation method therefor, relating to the technical field of production of flame-retardant polyurethane energy-saving materials and building energy conservation. An environmentally-friendly all-water-blown rigid inorganic hybrid melamine polyurethane foam material with B1-grade flame retardation performance according to the present invention is prepared with high-temperature-resistant inorganic hybrid melamine resin polyol or an inorganic hybrid polyol etherified melamine resin, an emulgator, a composite catalyst, a phosphate flame retardant, and a foamer, water or water glass for example, as main raw materials, and by carrying out dispersion by stirring, separately preparing premixed polyether, and then subjecting the premixed polyether to foaming on a sheet making machine, a coating machine, and a casting machine with isocyanate (MDI). The rigid foaming material according to the present invention is free of lower-boiling-point hydrocarbon compound chlorofluorocarbon and hydrochloroflurocarbon compounds, undergoes foaming in virtue of water, and does not destroy the ozone layer nor produce the greenhouse effect, so that the material is environmentally friendly; the flame-retardant property is improved by at least 20%; the material has excellent flame-retardant property while guaranteeing physical properties and has an oxygen index of more than 30%.
