Abstract

The invention relates to inorganic hybrid melamine polyurethane combined polyether and a preparation method thereof, which belong to the technical fields of production of environment-friendly and flame-retardant polyurethane energy-saving materials and building energy saving. High-temperature resistant inorganic hybrid melamine resin polyols, emulsifiers, composite catalysts, phosphate flame retardant and foamers are used as main raw materials, and the raw materials are stirred, dispersed and filtered to remove micro mechanical impurities, so that the inorganic hybrid melamine polyurethane combined polyether is obtained. According to the inorganic hybrid melamine polyurethane combined polyether, high-temperature resistant flame retardant elements such as boron, antimony, molybdenum and the like are introduced to the polyols of the raw materials, so that the high-temperature resistant performance and the flame retardant performance of the amino resin polyols are improved; the materials react with polymerized isocyanate (MDI) so as to form an inorganic hybrid melamine polyurethane foam material, the physical performance is excellent, the strength is high, powder fermentation and deformation do not occur, and the requirements of water resistance and thermal insulation of the GB50404-2007 standard and the flame retardance of level B1 of the GB8624-2012 standard are completely satisfied. The physical performance is guaranteed, additionally, the flame retardant performance is excellent, and the oxygen index is greater than 30%.

Description

technical field [0001] The invention belongs to the technical fields of production of environment-friendly and flame-retardant polyurethane energy-saving materials and building energy conservation, and in particular relates to melamine-polyurethane combination polyether and its manufacturing method. Background technique [0002] Because melamine resin has a certain temperature resistance, it is used in many fields, including coating industry, furniture industry, polyurethane industry and so on. However, when applied to highly flame-retardant polyurethane materials, there is still a certain gap in its high-temperature resistance. [0003] Due to the special molecular structure of polyurethane foam plastics, it is easy to burn and not resistant to high temperature. With the continuous popularization and application of polyurethane energy-saving thermal insulation rigid foam application technology, the requirements for its flame retardant performance are getting higher and hig...
