Abstract

The invention provides water-borne wood paint, which comprises the following ingredients in percentage by weight: 10 to 20 parts of deionized water, 1 to 5 parts of propylene glycol, 1 to 3 parts of base association type thickening agents, 0.05 to 0.5 parts of dimethylethanolamine, 0.01 to 0.5 parts of non-silicone mineral oil system defoaming agents, 0.05 to 0.3 parts of water-borne carboxymethyl cellulose, 0.2 to 1.2 parts of ethanol, 60 to 80 parts of water-borne nanometer core-case crylic acid polymer dispersoid, 3 to 10 parts of water-borne fluorine-containing polyurethane nanometer dispersoid, 1 to 5 parts of alcohol ester twelve coalescing agents, 0.01 to 0.05 parts of fluorine flatting agents and 0.1 to 0.3 parts of anticorrosive and bacterium prevention agents. The water-borne wood paint has the advantages that the water-borne fluorine-containing polyurethane nanometer dispersoid is used as the core technology and is organically combined with water-borne auxiliaries such as the fluorine flatting agents, the problem that the wood surface cannot be easily moistened by the water-borne wood paint because the water surface tension is strong is solved, and the problems of poor paint film adhesion force, poor boiled water resistance and the like of the ordinary water-borne wood paint are solved. The invention also provides a preparation method of the water-borne wood paint at the same time.

Description

technical field

[0001] The invention belongs to the field of water-based paint, and in particular relates to a water-based wood paint and a preparation method thereof. Background technique

[0002] At present, traditional solvent-based paints are still the main paints for wood. VOCs in paints can cause serious air pollution. The paints are flammable and explosive, and can easily cause occupational diseases for painters. Therefore, the state encourages the wood furniture industry and the home improvement industry to replace traditional paints with water-based paints. .

[0003] A lot of research work has been carried out on water-based wood paint at home and abroad, but the application cost remains high, and the requirements for equipment and construction environment are high during the application construction process, and the core properties such as hardness and adhesion of the finished paint film are difficult to meet. Require. The deficiencies in the three aspects of co...
