Flame-retardant molecular chain grafted mesoporous silica modified epoxy resin coating and preparation method thereof
ActiveCN113265186AGood flame retardant synergistic effectInhibitionFireproof paintsEpoxy resin coatingsSilicone fluidInorganic chemical compound
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.
