Water-based wood lacquer and preparation method thereof

Abstract

The invention relates to a water-based wood lacquer and a preparation method thereof. The water-based wood lacquer comprises the following components by weight: 78 to 85 percent of water-based acrylic resin, 0.1 to 0.2 percent of foam suppressing agent, 0.2 to 0.3 percent of antifoaming agent, 4 to 6 percent of film-forming auxiliary agent, 10 to 13.5 percent of nano-silica slurry, 0.1 percent of anti-corrosion fungicide, and 1.1 to 4.4 percent of water. The method adopts the water-based resin containing rigid acrylic monomers to enhance the polishing performance of the water-based wood lacquer and achieve the comprehensive performance with excellent performance price ratio; and a nanometer inorganic silica filler is added and is evenly dispersed in the system to improve the solid content of the product with excellent transparency, and the product has double performances of the two materials, thus the water-based wood lacquer with high solid content, high transparency and double performances is obtained.

Description

technical field [0001] The invention relates to a wood varnish, in particular to a water-based wood varnish and a preparation method thereof, which are applied to the fields of home decoration and wood furniture. 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. There are very few substances, non-flammable, non-explosive, non-yellowing, large painting area, and you can move in on the same day of painting. With the continuous enhancement of people's awareness of environmental protection, water-based wood paint is more and more popular in the market and favored by consumers. At present, water-based wood lacquers mainly include water-based acrylic and polyurethane systems in the market. In terms of sanding performance and cost, most choose to use water-based acrylic resin. Compared with the solid content of 65%-70% of oily resin, the solid ...

Problems solved by technology

At present, most of the fillers added in the market are talc powder, but because the refractive index of talc powder is quite different from that of water-based resin, when the addition amount is 10% of the system, although the filling property of the system is improved, However, the transparency of the product is greatly reduced, which affects the use effect of the product on wood, and due to the water absorption of talcum powder, the paint film may be prone to whitening over time. Therefore, most of the water-based wood paint products currently on the market There are certain quality risks in the application, and it is limited to light-colored substrates and cannot be popularized and applied universally.
