Abstract

The invention relates to a polyurethane poured self-heat-preservation wall body and a manufacturing and shaping method thereof, and belongs to the technical field of production of flame-resistant polyurethane energy-saving materials and energy saving of buildings. High-temperature resistant inorganic hybrid melamine resin polyalcohol or polyalcohol etherified melamine resin, an emulsifying agent, a composite catalyst, a phosphate ester fire retardant, and a foaming agent such as water or water glass, are used as main raw materials, the raw materials are stirred and dispersed so that combined polyether is prepared, and then the combined polyether and polymerized isocyanate MDI are foamed on a sheet material machine, a spraying machine and a pouring machine so that an environmental-friendly full water foamed B1-level flame-resistant inorganic hybrid melamine polyurethane hard bubble material is obtained; and the inorganic hybrid melamine polyurethane hard bubble material is poured between an inner wall body and an outer wall body, so that a polyurethane hard bubble heat-preservation sandwich layer is formed. The hard bubble material disclosed by the invention does not contain a low-boiling hydrocarbon compound namely fluorochlorohudrocarbon or HCF compounds, is foamed with water, does not destroy an ozone layer, does not generate greenhouse effects, and is environmental-friendly and excellent in flame resistant properties; and the flame resistant properties are improved by at least 20%, and the oxygen index of the hard bubble material is 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 conservation, and particularly relates to a polyurethane self-insulating wall and its manufacturing and molding method. Background technique [0002] my country is a large country with complex climate characteristics, such as the severe cold in the Northeast and the middle reaches of the Yangtze River in hot summer and cold in winter, which makes the energy consumption of building materials in my country very large. Winter warming in the northern region accounts for 27.3% of the country's total energy consumption. However, due to the problems of materials, technology and workmanship, the heating energy consumption 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 Energy Conservation" promu...
