Abstract

The invention relates to a water-based wood rib-expansion-resistant varnish primer and a preparation method thereof, particularly a water-based wood varnish primer, belonging to the field of architectural decoration paints. The primer is characterized by using a film forming matter as a single-component acrylic resin dispersion, and has the advantages of high drying speed, favorable sanding performance and rib expansion resistance. The water-based wood rib-expansion-resistant varnish primer comprises 80-90 parts of water-based acrylic resin dispersion, 0.1-0.2 part of pH regulator, 3-6 parts of film forming assistant, 0.5-1.5 parts of antifreezing agent, 0.1-0.3 part of defoaming agent, 0.1-0.2 part of anticorrosive bactericide, 0.4-1.2 parts of wetting and leveling agent, 0.3-0.8 part of thickener and 4-10 parts of water. The water-based wood varnish primer is used as a wood coating sealing primer, has the advantages of excellent rib-expansion-resistant effect, high sanding performance, high drying speed and favorable adhesion with the substrate, and can protect the substrate from being destroyed.

Description

technical field [0001] The invention relates to the field of coatings for architectural decoration, in particular to a water-based anti-expansion tendon clear primer for woodware and a preparation method thereof. Background technique [0002] With the advancement of my country's industrialization process, environmental problems have become increasingly prominent, and smog and photochemical pollution have seriously affected people's health. Since the beginning of the 21st century, environmental protection regulations have been further improved, and the research on new coatings with low or zero VOC emissions for the purpose of reducing the load on the earth is becoming a hot spot in research and development. Water-based wood lacquers have attracted much attention because of their low carbon and environmental protection. However, at present, water-based wood lacquers have many technical difficulties, such as tendon swelling, color bleeding and yellowing, etc. These technical d...
