High-temperature-resistant and high-dispersivity non-toxic pigment and preparation method thereof

Abstract

The invention discloses a high-emperature-resistant and high-dispersivity non-toxic pigment and a preparation method thereof. The high-temperature-resistant and high-dispersivity non-toxic pigment is prepared from the following raw materials in parts by weight: 40-60 parts of ferrous sulfate, 5-10 parts of Chia seed, 1-3 parts of eucalyptus essential oil, 1-3 parts of hydrogenated castor oil, 2-6 parts of guar gum, 10-14 parts of nano-sized silicon dioxide, 8-12 parts of nano-sized titanium dioxide, 4-8 parts of butyl acetate, 2-6 parts of okra slime, 4-6 parts of a dispersing auxiliary agent, 8-12 parts of a silane coupling agent KH-550, 4-14 parts of montmorillonite, 4-8 parts of shell powder, 3-8 parts of a thickening agent, 0.5-1.5 parts of bisphenol A and 3-5 parts of maifanite powder. The high-temperature-resistant and high-dispersivity non-toxic pigment particles have good dispersivity and uniform and appropriate strength, have the characteristics of strong coloring power, high light resistance and high heat resistance, have good solvent resistance and acid and alkali resistance, are unlikely to powder, fly and diffuse, are safe and non-toxic and have relatively good antibacterial performance, so that the application range of the pigment is greatly widened.

[0002] Pigment is a substance that can make objects dyed with color. Pigments are soluble and insoluble, and there are inorganic and organic differences. Pigments are mainly used in coatings, inks, printing and dyeing, plastic products, papermaking, rubber products and ceramics. With the rapid development of downstream industries, the demand for pigments continues to expand, and the development prospects of China's pigment industry are very broad; the color, light resistance, pulverization, heat resistance, solvent resistance and acid and alkali resistance of pigments will affect Its use and effect, the color is the result of the selective absorption of the white light component by the pigment, the physical properties of the pigment, such as dispersibility, affect the color within a certain limit, because the degree of dispersion affects the reflection conditions of the pigment, generally the smaller the particle size, the better the hue The darker the color, the greater the brightness; the color of the pigment changes to varying degrees under the action of light; under the condition of exposure to the sun, the pigment is often denatured, resulting in a change in color, and after exposure to the sun, the pigment is formed into a coating film. The film-forming substance will be destroyed, causing the surface pigments to be unable to be fixed in the coating film, and powdered and peeled off; in terms of toxicity, pigments can be divided into two categories: inorganic pigments and organic pigments according to their chemical composition. Inorganic pigments are light-fast, Good heat resistance and strong hiding power, but incomplete chromatogram, low tinting power, poor reading of color fiber, and high toxicity of some metal salts and oxides; organic pigments have various structures, complete chromatograms, bright and pure shades, and strong tinting power, but Light resistance, weather resistance and chemical stability are poor, and the price is expensive; the toxicology of organic pigments can be summarized as almost physiologically inert, that is, their basic safety, and the main factor affecting health mainly comes from their dusty state, that is, granular substances; However, in the intermediate or final products of pigments, dispersants, binders, solvents, etc. may be used to improve their physical and chemical properties. Therefore, to a large extent, existing pigments are more or less toxic. In view of this, It is of great research significance to explore and develop a non-toxic and environmentally friendly pigment on the basis of ensuring its physical and chemical properties
