Abstract

The invention relates to the technical field of paint, especially to a nitro-colored paint, which is composed of the following components by weight: 23-42.5% of a solvent; 10-20% of 1/4s nitrocotton; 4-7% of 1/2s nitrocotton; 5.5-10% of maleic resin; 12-20% of soybean oil modified alkyd resin; 1-6% of polyethylene wax powder; 1-3% of a segmented copolymer type dispersing agent containing pigment affinity groups; 3-5% of toner; 1-3% of a plasticizer; and 0.2-0.5% of a leveling agent. According to the invention, a high dosage of polyethylene wax is added to improve the smoothness and surface hardness of a paint film, and the fading phenomenon caused by friction can be effectively reduced. In addition, by making use of the superstrong wetting and dispersion properties of the high molecular weight dispersing agent with polyfunctional groups and multi-adsorptive groups on the organic toner, the packaging of the toner by a paint base is substantially reinforced. Thus, the fading phenomenon caused by wiping is also greatly improved.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a nitro colored paint. Background technique [0002] Nitro lacquer is a relatively common wood and decoration coating at present. The main film-forming material of nitro lacquer is mainly nitrocellulose, combined with alkyd resin, modified rosin resin, acrylic resin, amino resin and other soft and hard resins. Generally, plasticizers such as dibutyl phthalate, dioctyl phthalate, and oxidized castor oil need to be added. Solvents mainly include true solvents such as esters, ketones, and alcohol ethers, co-solvents such as alcohols, and diluents such as benzene. Nitro lacquer is mainly used in wood and furniture coating, home decoration, general decorative coating, metal coating, general cement coating and so on. [0003] Just because nitro lacquer is mainly used for wood, household painting, home decoration, etc., people will frequently come into contact with nitro lacque...
