Abstract

The invention relates to a nitro wear-resistant matte varnish capable of electrostatic spraying and a preparation method thereof, belonging to the field of chemical paints. The nitro wear-resistant matte varnish capable of electrostatic spraying is prepared from a main agent and a diluter in a weight ratio of (1-1.5):(1.5-2.3). The main agent is prepared from the following raw materials in parts by weight: 10-18 parts of alkyd resin, 2-6 parts of rosin emulsion, 50-60 parts of nitrocellulose slurry, 0.1-2 parts of matte powder, 0.1-0.3 part of leveling agent, 0.2-0.5 part of defoaming agent, 0.8-1.5 parts of epoxy soybean oil, 1-3 parts of anti-settling agent, 0.7-1.2 parts of wax powder, 3-7 parts of glass powder and 18-25 parts of mixed environment-friendly solvent. The matte varnish is suitable for electrostatic spraying, and has the advantages of high construction safety and reliability and high efficiency; and the formed paint film has favorable scratch resistance, can not easily generate orange peel or nonuniform surface even in a high-temperature working environment, and can not become white.

Description

technical field [0001] The present invention relates to a nitro matte varnish and a preparation method thereof, in particular to an electrostatically sprayable nitro wear-resistant matte varnish and a preparation method thereof; the electrostatically sprayable nitro wear-resistant matte varnish prepared by the present invention can be Applied to all kinds of furniture, especially suitable for irregular-shaped wooden furniture; belongs to the field of chemical coatings. Background technique [0002] With the rapid development of the modern coatings industry, people have found that electrostatic spraying of nitro paint on the substrate can not only maintain its performance, reduce corrosion and wear, but also dry the coating quickly. In addition, electrostatic spraying can save a lot of paint In addition to the cost, the traveling direction of the charged paint particles can also be changed. When spraying from one direction, the paint particles can be deposited on the top, bot...
