Abstract

The invention discloses a water-based transparent colored paint for wooden ware and a preparation method of the paint. The water-based transparent colored paint is applied to decoration of the surface of a wood material (cabinets, tables, chairs, chair rails and the like). The water-based transparent colored paint comprises components including water-based emulsion / dispersoid, a water-based color concentrate, pure water, a film forming aid, a wetting dispersant, a foam killer, a flatting agent, a bactericide, a mildew preventive, an anti-freezing agent, a thickening agent, a multi-functional additive, a matting agent and wax emulsion. The water-based transparent colored paint for the wooden ware is bright in color and clear in texture and has the effects of greatly reducing the content of VOC, guaranteeing the application performance of the product and realizing the environmental protection characteristics of the product.

Description

technical field [0001] The invention belongs to the technical field of coatings, and in particular relates to a water-based transparent wood varnish and a preparation method thereof. Background technique [0002] At present, home decoration has become a fashion. In terms of paint for home wood decoration, most families still use solvent-based wood paint. These products use a large amount of toxic, harmful, easily polluting, and flammable organic solvents. During or after construction, a large amount of toxic and harmful gases such as benzene and free TDI are volatilized, causing serious indoor pollution. According to a report released by the China Consumers Association, one-third of leukemia children's incidence is directly related to home decoration, and ordinary solvent-based wood paint has become a "killer" that pollutes the environment and damages consumers' health. Contents of the invention [0003] The purpose of the present invention is to provide a kind of water-b...
