American type water-based coating finish paint and preparation method thereof

Abstract

The invention provides an American type water-based coating finish paint and a preparation method thereof. The finish paint comprises the following components in mass percent: 5-25% of self-crosslinking acrylic emulsion, 30-50% of polyurethane modified acrylic emulsion, 5-30% of polyurethane dispersion emulsion, 0.05-0.1% of macromolecular segmented copolymer solution containing pigment affinity groups, 0.1-0.3% of polysiloxane mixture, 0.2-0.5% of organic silicon flatting agent, 0.05-0.2% of primary amine multifunctional additives, 0.5-2% of silica matting powder, 1-4% of dipropylene glycol methyl ether, 3-5% of dipropylene glycol butyl ether, 5-10% of deionized water, 2-4% of polyethylene wax water-based dispersion, 0.2-0.4% of polyether siloxane copolymer emulsion, 0.1-0.3% of non-ionic special polyurethane polymer, 0.1-0.3% of polysiloxane-polyether copolymer and 0.3-3% of one or two of silane coupling agent and aziridine. The finish paint provided by the invention is used for solid wood substrates, is environment-friendly and has excellent performance, and the adhesive force, glossiness and hardness of the finish paint can meet the operating requirements of indoor decoration of wooden furniture.

Description

technical field [0001] The invention relates to a finishing paint for painting, in particular to an environmentally friendly and excellent performance American-style water-based finishing paint for painting and a preparation method thereof. Background technique [0002] At present, most of the wood finishes sold and used in our country are solvent-based wood finishes, which generally contain a large amount of volatiles. These volatiles are mainly carcinogens such as benzene, toluene, xylene, and TDI, which can damage human nerves, mucous membranes, skin, The liver and trachea cause damage and even cause cancer, seriously endangering the health of producers and users. With the enhancement of people's awareness of environmental protection, the environmental pollution problems caused by solvent-based paints are gradually being paid attention to by people. Therefore, low-toxic, non-flammable, and low-pollution water-based wood paints have become the direction and trend of wood p...
