Water-based high-volume wood coatings suitable for electrostatic spraying

Abstract

The invention discloses a water-based high-volume wood coating suitable for electrostatic spraying, which belongs to the technical field of coatings. The water-based high-volume wood coating comprises 20-40% of water-based acrylic emulsion and 20-40% of water-based Polyurethane emulsion, 4‑6% film-forming solvent, 15‑20% titanium dioxide, 0.5‑1% defoamer, 1.5‑2% dispersant, 2‑4% rheology additive, 0.5‑1 % of wetting and leveling agent and 2‑5% of hand additive. The water-based high-volume wood coating provided by the invention is suitable for coating by electrostatic spraying. During electrostatic spraying, problems such as gelling, wire drawing, and inability to form a continuous and uniform paint film will not occur. Through the improvement of the formula, the electrostatic spraying is improved The wrapping property makes the paint film leveling on the sprayed board better, the fineness is higher, and the mechanical properties of the paint film are enhanced, thus realizing the high fullness of the paint film.

Description

technical field [0001] The invention belongs to the technical field of coatings, and in particular relates to a water-based high plump wood coating suitable for electrostatic spraying. Background technique [0002] With the advent of the era of low-carbon economy, environmental protection and energy have become two major challenges faced by mankind in the 21st century. To cope with this challenge, the paint industry is gradually changing from traditional varieties with high pollution, high energy consumption, and extreme dependence on petroleum industry products to water-based products. Transformation of environmentally friendly and resource-saving products such as coatings, radiation-curable coatings, powder coatings and high solids coatings. Water-based wood coatings are one of the main varieties of industrial coatings, which refer to water-based coatings used for decoration and protection on wood products. Water-based wood coatings are the development direction of the fu...

AI Technical Summary

Problems solved by technology

However, most of the water-based wood coatings currently on the market cannot be painted under high pressure. If such ordinary water-based wood coatings are forcibly used for electrostatic spraying, it is prone to gelation, wire drawing, and cannot form a continuous and uniform paint film. question
