Organic silicon hybridized melamine cyanurate as well as preparation method and application thereof

The invention relates to organic silicon hybridized melamine cyanurate, which is methyl vinyl phenyl silazane urea cyanamide, and the organic silicon hybridized melamine cyanurate is prepared from the following raw materials in parts by mole: 1 part of melamine cyanurate, 1-2 parts of silicon tetrachloride, 1-2 parts of methyl vinyl dichlorosilane and 1-1.5 parts of phenyl trichlorosilane. The preparation method comprises the following steps: adding the raw materials into a fluidized bed according to a required ratio, carrying out condensation polymerization at 130-180 DEG C until no hydrogen chloride gas is released to obtain a polymer material, washing the polymer material with water, removing low-boiling-point materials at 100-120 DEG C, cooling residual materials, filtering, taking a filter cake, and finally washing and drying the filter cake in sequence. According to the design, the flame retardant property is further improved, the ceramic sintering function is achieved when the flame retardant is used f
