Abstract

The invention relates to a waterborne woodware surface color modifier, which is mainly prepared from the following ingredients (by weight): 90-95 parts of a waterborne polyurethane dispersion, 0.1-0.2 part of a pH regulator, 2.5-3.5 parts of a coalescing agent, 0.5-1 part of an antifreezing agent, 0.1-0.3 part of an antifoaming agent, 0.5-1 part of an inorganic anticorrosion and bactericidal agent, 0.1-1 part of an adhesion promoter, 0.4-1 part of a leveling wetting agent, 2-5 parts of waterborne color concentrate and 450-550 parts of alcohol. The waterborne woodware surface color modifier is used for color modification of waterborne woodenware surface, has advantages of uniform color modification, excellent adhesion to a primer, good transparency and lasting and effective anticorrosion and antibacterial effect, and is green and environmentally friendly.

Description

technical field [0001] The invention relates to the technical field of wood coating, in particular to a water-based wood surface repairing agent. technical background [0002] In recent years, water-based wood paint has gradually attracted people's attention because of its health and environmental protection. With the introduction of the most stringent environmental protection law, the punishment for violations of laws and regulations has been increased, and 4% is imposed on paints with VOC content above 420g / L. Consumption tax, which will greatly promote the promotion of water-based wood paint. However, in the transparent coating of water-based wood lacquer, when the main paint for surface correction is mixed with alcohol-soluble color essence and alcohol, due to the poor compatibility between the water-based resin in the main paint and the color essence, the water-based emulsion will break into slag and the color correction will be blurred. , unevenness, etc., which to a ...
