Abstract

The invention particularly discloses a flame-retardant molecular chain grafted mesoporous silica modified epoxy resin coating and a preparation method of the flame-retardant molecular chain grafted mesoporous silica modified epoxy resin coating. The method relates to synthesis of a flame-retardant molecular chain and a preparation process of aminated mesoporous silica, and the flame-retardant molecular chain grafted mesoporous silica is obtained through an ammonium phosphate reaction. The flame-retardant molecular chain grafted mesoporous silica modified epoxy resin coating is synthesized by taking epoxy resin, flame-retardant molecular chain grafted mesoporous silica, glycerol monostearate, organic micronized wax powder and simethicone as raw materials. The problems that an inorganic compound flame retardant is weak in flame retardance, a traditional epoxy resin coating is poor in toughness and the like are solved; and the flame retardance and mechanical performance of the epoxy resin coating are improved through the good synergistic effect of the flame-retardant molecular chain and mesoporous silica.

Description

technical field [0001] The invention relates to the technical field of epoxy resins, in particular to a flame retardant molecular chain grafted mesoporous silica modified epoxy resin coating and a preparation method thereof. Background technique [0002] As one of the five major synthetic polymer materials in my country, coatings rank first in the world in terms of output worldwide. Like most polymer materials, they are flammable and combustible. With the development of the economy, coatings are widely used in daily life. The use and application in various industries are becoming more and more extensive. It is inevitable to consider its flammability. During the combustion process of coatings, it will be accompanied by the generation of smoke and the phenomenon of molten dripping. The flame spreads quickly and It is not easy to extinguish, causing casualties and huge economic losses. Endowing the coating with flame retardancy and flame-retardant treatment is an important way to...
