Abstract

The invention relates to nitro white finish and in particular relates to modified high-weatherability high solid environment-friendly nitro white finish and a preparation method thereof. The modified high-weatherability high solid environment-friendly nitro white finish can be applied to home decoration and coating of furniture and artware and is prepared from the following raw materials in parts by weight: 35-50 parts of nitrocotton pulp, 3-8 parts of synthetic fatty acid resin, 1-5 parts of modified amino resin, 3-8 parts of aldehyde ketone resin liquid, 3-10 parts of environment-friendly mixed solvent, 0.1-1.0 part of antisettling agent, 0.1-1.0 part of dispersing agent, 0.1-0.5 part of defoaming agent, 0.1-0.5 part of levelling agent, 0.5-4 parts of extinction powder, 36-45 parts of wheat flour paste, 1-3 parts of environment-friendly plasticizer and 0.3-1 part of ultraviolet absorbent. The modified high-weatherability high solid environment-friendly nitro white finish has high weatherability and high solid; meanwhile, coating efficiency can be improved, and coating cost can be reduced.

Description

technical field [0001] The invention relates to a nitro wood varnish, in particular to a modified high-weather resistance and high solid content environment-friendly nitro white finish paint and a preparation method thereof, which can be used for home decoration, furniture and handicraft coating. Background technique [0002] At present, the weather resistance and fullness of nitro wood lacquers are quite different from those of polyurethane wood lacquers; although the existing nitro wood lacquers are easy to construct, they have low solid content and need to be painted many times to meet the requirements. In addition, due to the characteristics of nitrocellulose itself, the weather resistance of existing nitro products is much worse than that of polyurethane coatings. As consumers have higher and higher requirements for paint films, the market share of nitro products has been increasing. However, the quick-drying advantages of nitro are still favored by many consumers, so d...
