The invention discloses flame-retardant calcium carbonate wood plastic and belongs to the technical field of wood plastic materials. The flame-retardant calcium carbonate wood plastic comprises, by weight, 20-50 parts of flame-retardant calcium carbonate, 5-80 parts of wood fibers, 1-8 parts of stearic acid and 1-6 parts of pigment. The invention further discloses a preparation method of the wood plastic. According to the flame-retardant calcium carbonate wood plastic, calcium carbonate modified through PE wax is added, so that flame retardancy is lowered to 200 DEG C or below; meanwhile, PE and PP are added to improve impact resistance of calcium carbonate, so that a wood plastic product is high in bending strength, flexural modulus and unnotched impact strength, and the flame-retardant calcium carbonate wood plastic can partially replace structural materials; by means of the preparation method of the flame-retardant calcium carbonate wood plastic, good practicability is achieved, and good economic benefits and social effects are achieved. |
