The aqueous coating material comprises the ingredients in percentage by weight: 55%-62% of acrylic acid, 11%-13% of epoxy resin, 2.5%-3% of propylene glycol methylether acetate (PMA),0.2%-1.5% of substrate humectant, 0.05%-0.5% of antifoamer, 0.08%-0.2% of leveling agent, 3%-6% of sodium silicate, 0.36%-0.45% of nano-silver, 4%-5% of trisodium citrate and the balance of water, wherein a weight ratio of the acrylic acid to the epoxy resin is (4.5: 1) to (5.3: 1), and a weight ratio of the trisodium citrate to the nano-silver is (10: 1) to (13: 1). The coating material has a good cured film forming property, the surface drying time is 20min or less, the solid drying time is 42min or less, the adhesive power is relatively high and is 8.2MPa or more, the elimination rate of Escherichia coli is 49% or more under the condition of 24h of culturing, and the heat-resisting temperature is 160 DEG C or above.

Description

technical field [0001] The invention belongs to the field of paint material preparation, and in particular relates to a water-based paint for furniture production, a preparation method, an application and a furniture preparation process. Background technique [0002] Water-based coatings, that is, coatings that use water as a diluent, are a new generation of wood-based paints developed to overcome the shortcomings of solvent-based coatings, such as poor environmental performance and high resource dependence. There are many types of water-based coatings, which can be divided into alcohol Acids, polyurethanes, acrylics, epoxies, etc., each with different characteristics. [0003] Waterborne epoxy resin coating has strong mechanical properties, electrical insulation properties, adhesion and chemical resistance, and also has the characteristics of low pollution, non-toxic, and simple construction technology. Water-based epoxy resin coatings are composed of water-based epoxy emu...
