Melamine cyanuric acid flame retardant and preparation method thereof
By adding specific proportions of flame retardant fillers and crosslinking agents containing isocyanate groups to the melamine cyanuric flame retardant, the composite is formed, and the existing flame retardant is solved by solving the high-temperature aging resistance and wear resistance in silicone materials. In addition, better mechanical, wear resistance and flame retardant properties have been achieved.

Abstract
The invention relates to the field of flame retardant production, in particular to a melamine cyanuric acid flame retardant and a preparation method thereof. The preparation method comprises the following steps: 1) weighing melamine and water, uniformly mixing, heating, adding cyanuric acid, a flame-retardant filler and alkali metal, uniformly mixing, and reacting until the viscosity is 8000-9000 mPa.s to obtain a reactant A; weighing a cross-linking agent containing an isocyanate group, polysilazane, tris (2-hydroxyethyl) isocyanuric acid triacrylate, alkyl acrylate phosphate, peroxide and a solvent, and uniformly mixing to obtain a mixture B; and 2) carrying out suction filtration on the reactant A to obtain a flowable white viscous material, adding the flowable white viscous material into the mixture B, uniformly mixing, reacting, drying, and crushing to obtain the melamine cyanuric acid flame retardant. The melamine cyanuric acid flame retardant prepared by the process has excellent compatibility, wear resistance, high temperature resistance, mechanical property and flame retardant property.
