Problems solved by technology

[0002] With the increasing requirements of artists for painting materials, especially oil paint is the most beloved painting material for artists to inherit paintings. The quality of vegetable oil and pigment fillers in traditional oil paints is easily separated, resulting in unstable quality. Traditional rheological additives (hydrogenated Castor oil, beeswax, stearic acid, etc.) oil paints have high viscosity and are prone to sticky pens and sticky pens during the artist's painting process

Abstract

The invention discloses an oil painting pigment, which comprises the following components, by weight percentage, 22.85-52.9% of linseed oil, 1-3% of cera alba, 1-3% of monostearin, 0.1-0.2% of a drying agent, 15-50% of barium sulfate, and 5-30% of pigment powder. The pigment is free of pungent smell, is safe and non-toxic, can directly contact the human body, and is excellent in water solubility. The pigment is easy to be washed off and is green and eco-friendly. The technical problems that an oil painting pigment in the prior art adheres to pencils and oil and power is prone to separate are solved, the painting quality can be improved, materials are saved, and environmental pollution is reduced.

Description

technical field [0001] The invention relates to pigments, in particular to an oil paint. Background technique [0002] With the increasing requirements of artists for painting materials, especially oil paint is the most beloved painting material for artists to inherit paintings. The quality of vegetable oil and pigment fillers in traditional oil paints is easily separated, resulting in unstable quality. Traditional rheological additives (hydrogenated Castor oil, beeswax, stearic acid, etc.) produce oil paints with high viscosity, which is prone to sticky pens and stagnant pens during the artist's painting process. Contents of the invention [0003] In order to overcome the above defects, the invention provides an oil paint with moderate viscosity and good painting effect. [0004] The present invention is realized through the following technical solutions: [0005] A kind of oil paint, comprises following component by weight percentage, [0006] Linseed oil 22.85~52.9 ...
