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%.

Description

Technical field [0001] The invention belongs to the technical field of flame-retardant polyurethane energy-saving material production and building energy-saving technology, and particularly relates to a water-foamed polyurethane rigid foam material and a manufacturing method thereof. Background technique [0002] my country is a big country with complex climatic characteristics, such as the severely cold northeast region and the middle reaches of the Yangtze River with hot summers and cold winters. This makes the energy consumption of building materials in my country very large. The energy consumption of winter warmth in the northern region accounts for 27.3% of the country's total energy consumption. However, due to the problems of materials, technology and craftsmanship, the heating energy per unit area of ​​traditional buildings in my country is 2-3 times that of developed countries with similar climate conditions in the world. The "Medium and Long-term Special Plan for Energ...
