Abstract

The invention discloses flame retardant foam plastic and a preparation method thereof, and relates to the technical field of foam plastic preparation. The plastic is prepared from, by weight, 76-84 parts of polystyrene, 12-16 parts of flame retardants, 5-8 parts of binder, 6-9 parts of lubricant, 4-8 parts of foaming agent and 0.5-0.8 part oftalc, the flame retardant is formed by mixing a mixtureA and a mixture B according to the mass ratio of 1:2, the mixture A is formed by mixing anhydrous phosphoric acid, tris(2-chloroethyl) phosphate and dimethyl methylphosphonate at a mass ratio of 2:1:1, and the mixture B is obtained by mixing decabromodiphenylethane and magnesium hydroxide at a mass ratio of 1:2. The plastic solves the problem that foam plastic has poor flame retardancy, and the flame retardant which is a mixture of the mixture A and the mixture B is added to raw materials, thereby improving the flame retardancy of the foam plastic.
