Abstract

The invention belongs to the technical field of inorganic hybridized polymer materials and particularly relates to inorganic hybridized isooctanol etherified melamine resin and a preparation method thereof. The preparation method mainly includes steps: (1) etherification reaction, to be more specific, adding hexamethylol melamine and isooctanol into a reactor, and performing thermal reaction to obtain tetra-etherified or penta-etherified melamine resin; (2) alkali neutralization; (3) hybridization reaction; (4) distillation for removing residual isooctanol; (5) cooling and filtering to obtain a finished product. The inorganic hybridized isooctanol etherified melamine resin prepared according to the method has advantages that by hybridization cross-linking reaction with inorganic hybrid compounds, high-temperature flame-retardant elements such as boron and stibium are added into amino resin generated finally, and accordingly high temperature resistance and flame retardation of the amino resin are improved, and the resin is mainly applied to preparation of combined polyether and paint.

Description

technical field [0001] The invention belongs to the technical field of inorganic hybrid polymer materials, and in particular relates to an inorganic hybrid isooctanol 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 perform...
