Description
Technical Field
The invention relates to the technical field of pigments, in particular to an antibacterial pigment and a preparation method thereof.
Background
Pigment means a substance that can color an object. Pigments are distinguished by being soluble and insoluble, inorganic and organic. Inorganic pigments are generally mineral substances, and it has long been known to use inorganic pigments to draw and paint the body on the rock wall by using colored soils and ores. The organic pigment is generally extracted from plants and marine animals, such as alizarin, gamboge and ancient Rome, to obtain purple color from shellfish.
The pigment is divided into an inorganic pigment and an organic pigment, the organic pigment is prepared by extracting pigment from plants, does not contain elements harmful to human bodies, belongs to an environment-friendly pigment, and is mainly applied to the industries of paint, printing ink, printing and dyeing, plastic products, papermaking, rubber products, ceramics and the like.
Pigments (pigments) are used for coloring powdery substances. The natural pigment is insoluble in media such as refined sunflower seed oil, grease, resin, organic solvent and the like, but can be uniformly dispersed in the media, can color the media and has certain covering power. The art pigment basically requires that the finer the particles, the brighter the color, and the longer the color, the better the color will not change (the better the stability). Refined sunflower seed oil color pigment is almost transparent except for white. Thus, the requirement of color-cover dyeing of refined sunflower seed oil can be met.
The oil painting (a painting in oils) is a kind of painting made on canvas linen, cardboard or wood board by blending pigments with quick-drying vegetable oil (linseed oil, poppy oil, walnut oil, etc.). The diluent used in drawing is volatile turpentine oil, dry linseed oil, etc. The paint attached to the picture has strong hardness, and can keep luster for a long time after the picture is dried. The painting object is fully expressed by virtue of the covering power and the transparency of the pigment, and the painting object is rich in color and strong in three-dimensional texture. The oil painting is one of the main painting types of western painting.
