Water-based wood white finish paint resistant to tannin caused change, and preparation method thereof

The invention relates to the technical field of paint, in particular to water-based wood white finish paint resistant to tannin caused change, and a preparation method thereof. The water-based wood white finish paint is prepared from the following components in parts by weight: 50-60 parts of ammonium zirconium carbonate modified water-based acrylic emulsion, 0.4-0.8 part of a defoaming agent, 0.5-1.5 parts of a wetting agent, 3-5 parts of a film-forming assistant, 0.1-0.2 part of a neutralizer, 0.1-0.5 part of an in-can bactericide, 0.2-1 part of a rheological assistant, 0.5-3 parts of extinction powder, 18-20 parts of titanium dioxide, and 10-20 parts of deionized water. Compared to the prior art, the water-based wood white finish paint according to the invention adopts the ammonium zirconium carbonate modified water-based acrylic emulsion, so that after the water-based wood white finish paint is applied to base materials containing tannin, nicotine stains and water-soluble pigment,a good lasting sealing ef
