Abstract

The invention discloses an antibacterial pigment which is prepared from the following raw materials: refined sunflower seed oil, tea saponin, toner, starch ether, silicone oil, aluminum stearate, monoglyceride, carrageenan, barium sulfate, titanium zinc white, chitosan modified talcum powder, potassium sorbate, propylene glycol, sodium dodecyl benzene sulfonate, tetradecanol oleate and isothiazolinone. The cost is low, the alkali resistance is good, sterilization and bacteriostasis are achieved, and according to GB1741-79 (89) detection, the bacteriostasis rate on staphylococcus aureus, escherichia coli and the like is 96%; the antibacterial pigment is non-toxic, harmless, excellent in wear resistance, non-yellowing, not easy to crack and easy to clean, and the water resistance is detected to be 4-5 level according to GB / T5211.5-85; the antibacterial pigment is simple, safe, environment-friendly, harmless to human body, good in dispersity, film-forming property, heat resistance, steam resistance and weather resistance, and fine in quality; and the antibacterial pigment is bright in color, can be widely used in various extreme environments, is light-resistant, has the surface drying time of 5 minutes and the hard drying time of 2 hours, and can be widely produced and continuously replace the existing materials.

Description

technical field [0001] The invention relates to the technical field of pigments, in particular to an antibacterial pigment and a preparation method thereof. Background technique [0002] Pigment refers to a substance that can make an object dyed with color. Pigments are soluble and insoluble, and there are inorganic and organic differences. Inorganic pigments are generally mineral substances. Humans have known for a long time to use inorganic pigments, using colored soil and ores, to paint on rock walls and smear their bodies. Organic pigments are generally obtained from plants and marine animals, such as madder indigo, garcinia cambogia, and ancient Roman purple extracted from shellfish. [0003] Pigments are divided into two types: inorganic pigments and organic pigments. Organic pigments are made from pigments extracted from plants and do not contain harmful elements to the human body. They are environmentally friendly pigments and are mainly used in coatings, inks, pri...
