Abstract

The invention relates to acrylic acid modified nitro anti-corrosion lacquer and a preparation method thereof. The lacquer comprises, by weight, 30-45 of acrylic acid nitro slurry, 50-70 of nitro lacquer exterior materials and 0.01-0.02 of 1% of silicone oil butyl acetate liquids. The method comprises steps of adding the nitro lacquer exterior materials and the 1% of silicone oil butyl acetate liquids to a lacquer mixing tank in accordance with the ratio, stirring the nitro lacquer exterior materials and the 1% of silicone oil butyl acetate liquids for 10 minutes under the speed of 200-400 turns per minute, adding the acrylic acid nitro slurry in accordance with the ratio, stirring for 30 minutes under the speed of 600-800 turns per minute, and conducting detection, filtration and packaging. The lacquer and the method have the advantages that nitrocellulose resin with proper viscosity is selected preferably, a mixed solvent with proper solubility and volatilization speeds is prepared, the acrylic acid resin with low glass transition temperature (Tg-20 DEG C) is produced, the nitro lacquer is modified and plastified, zinc phosphate with low lead content is selected, and technical requirements of the anti-corrosion lacquer of steel structures and car parts and limit requirements for four soluble heavy metals are met.

Description

technical field [0001] The invention belongs to coatings, in particular to an acrylic modified nitro anticorrosion paint and a preparation method thereof. Background technique [0002] Nitro lacquer is a kind of volatile self-drying paint, which forms a continuous coating film by solvent volatilization, and does not undergo chemical changes during the film-forming process. It uses nitrocellulose as the main film-forming substance, and is mixed with synthetic resin, plasticizer, solvent, etc. to make the base material. Among them, the transparent base material without pigment is nitro varnish. Nitro paint has the characteristics of fast drying, convenient coloring, quick construction and good paint film performance, so it is widely used in the furniture industry. Traditional solvent-based lacquers use organic solvents such as toluene, xylene, ethanol, and butyl ester as dispersion media. These organic solvents not only pollute the environment, but also damage human health. ...
