Abstract

The invention belongs to the technical field of inorganic hybrid polymers and especially relates to inorganic hybrid polyester polyol etherified melamine resin and a preparation method thereof. The preparation method mainly comprises the following steps: (1) etherification reaction: adding hexamethylolmelamine and polyester polyol into a reaction vessel to carry out a thermal reaction so as to obtain tetraetherified or pentaetherified melamine resin; (2) alkali neutralization; (3) hybridization reaction; (4) cooling and filtering to obain the finished product. Through the above method, the inorganic hybrid polyester polyol etherified melamine resin is prepared. By hybridization cross-linking reaction with an inorganic hybrid compound, high-temperature-resistant fire retardant elements such as boron, molybdenum, antimony, etc. are introduced into the finally produced amino resin polyol such that high temperature resistance and flame retardant property of amino resin polyol are enhanced. The product of the invention is mainly used in preparation of premixed polyols and paint coating.

Description

technical field [0001] The invention belongs to the technical field of inorganic hybrid polymer materials, and in particular relates to an inorganic hybrid polyester polyol etherified melamine resin and a preparation method thereof. Background technique [0002] Because amino 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 higher, especially GB8624-2012 "Classification method for the combustion p...
