Environmental protection and high-efficiency flame retardant treating agent and preparation method thereof

The invention relates to the field of flame retardants, in particular to an environmental protection and high-efficiency flame retardant treating agent and a preparation method thereof. The treating agent comprises the following components in percentage by weight: 5-15 percent of sodium metasilicate, 5-15 percent of water-soluble amino silicon oil, 5-15 percent of urea and the balance of water and other impurities. Compared with the prior art, the environmental protection and high-efficiency flame retardant treating agent is transparent liquid without color, taste, toxicity and radioactivity and is widely applied to materials such as wood, plywood, flax boards, yellow board paper, wallpaper, cloth, carpets, and the like. After the treating agent is sprayed, the color of an original material cannot be changed, and the decoration effect of the original material cannot be influenced. The oxygen index of a material treated by the environmental protection and high-efficiency flame retardant treating agent is large
