Modified acrylic resin energy-saving and environment-friendly coating material for cabinet of washing machine

Abstract

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.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to an energy-saving and environment-friendly modified acrylic resin coating for a washing machine box. Background technique [0002] Water-based paint is a paint that uses water as a solvent or as a dispersion medium. It is a relatively new type of paint in the paint market, including water-soluble paint, water-diluted paint, and water-dispersible paint (latex paint). Water-based coatings use water-soluble resins as film-formers, represented by polyvinyl alcohol and its various modified products, in addition to water-soluble alkyd resins, water-soluble epoxy resins, and inorganic polymer water-based resins. Water-based paint has no pollution to the environment, has little impact on human health, easy to adjust viscosity, and low volatility, making it suitable for spraying, but it still has disadvantages such as no alkali resistance, no water resistance, slow drying, and easy shrink...

AI Technical Summary

Problems solved by technology

However, the linear structure of acrylic resin leads to its disadvantages such as poor dispersion, low adhesion, poor flexibility, and poor heat resistance. Therefore, it is necessary to modify acrylic resin, and the development and application of modified acrylic resin coatings have broad prospects.
