Abstract

The invention belongs to the technical field of inorganic hybrid polymeric materials, and especially relates to an inorganic hybrid butylated melamine resin and a production method thereof. The production method mainly comprises the following steps: 1, carrying out an etherification reaction: adding hexamethylolmelamine and butanol to a reaction kettle, and carrying out a heat insulation reaction to obtain tetraetherified or pentaetherified melamine resin; 2, neutralizing with an alkali; 3, carrying out a hybrid reaction; 4, distilling to remove residual butanol; and 5, cooling and filtering to obtain the finished product. A hybrid cross-linking reaction with an inorganic hybrid compound makes boron, molybdenum, antimony and other high temperature-resistant flame retardation elements be introduced to finally generate amino resin, so the high temperature resistance and the flame retardation performance of the amino resin are improved, and the obtained amino resin is mainly used to prepare combined polyether, paints and coatings.

Description

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