Abstract

The invention discloses a water-borne wood paint, and a preparation method thereof. The water-borne wood paint is prepared from following raw materials: a resin, a pigment, a filling material, an auxiliary agent, and water, wherein the resin is a mixed resin of water-based acrylic resin and acrylic acid modified waterborne polyurethane resin, or a mixed resin of water-based acrylic resin and waterborne polyurethane resin. The water-borne wood paint is high in strength, possesses excellent chemical resistance, gloss retention, colour retention, and base material permeability, high transparency; obtained films possess water resistance, boiling water resistance, low film forming temperature, and excellent levelling properties; after-tack is not caused; solid content is high; a plurality of steps are avoided; the water-born wood paint is dried quickly at normal temperature; the obtained films are flat and well-rounded; polyurethane paint possesses excellent adhesive force and wear resistance, and is bright and well-rounded, so that the water-born wood paint can be used for painting as a wooden floor paint.

Description

technical field [0001] The invention belongs to the technical field of coatings, and more specifically, the invention relates to a water-based wood varnish and a preparation method thereof. Background technique [0002] Water-based wood paint is a special paint with water as the dispersion medium. It does not contain harmful substances such as benzene, xylene, and free TDI. Less, non-flammable, non-explosive, non-yellowing, large area to be painted, and occupancy on the same day of painting. [0003] Water-based wood lacquers mainly include water-based acrylic and polyurethane systems in the market. Water-based acrylic wood paint has become the main product in the market due to its low cost and environmental protection, but its paint film has poor wear resistance, chemical resistance and boiling water resistance, low hardness, and poor fullness, which cannot meet people's expectations for high-quality products. requirements. Contents of the invention [0004] Based on t...
