The invention discloses a modified acrylic resin energy-saving and environment-friendly coating material for a cabinet of a washing machine. The modified acrylic resin energy-saving and environment-friendly coating material is prepared from the following raw materials in parts by weight: 20 to 40 parts of thermosetting acrylic resin, 18 to 35 parts of water-borne epoxy resin, 15 to 30 parts of water-borne polyurethane resin, 0.6 to 2 parts of oxidized graphene, 2 to 5 parts of magnesium oxide, 1 to 3 parts of nano silica, 3 to 8 parts of expanded graphite, 3 to 8 parts of kaolin, 1 to 3 parts of a non-ionic surfactant, 2 to 4 parts of a water-borne defoaming agent, 2 to 4 parts of a water-borne antirust agent, 1 to 5 parts of benzoic acid, 10 to 20 parts of polyol and 25 to 50 parts of water. Compared with a traditional coating material, the dispersibility, the adhesive ability, the heat resistance and the flame resistance of the modified acrylic resin energy-saving and environment-friendly coating material are effectively increased, the modified acrylic resin energy-saving and environment-friendly coating material has the characteristics of safety and environment protection, a preparation method of the modified acrylic resin energy-saving and environment-friendly coating material is simple, the preparation cost is low, the modified acrylic resin energy-saving and environment-friendly coating material is used for spraying the cabinet of the washing machine, the glossiness is good, very good protection and decoration functions can be achieved, the service life of the washing machine can be effectively prolonged, and the modified acrylic resin energy-saving and environment-friendly coating material is worthy of promotion.
