Preparation method of noctilucent luminous pigment

Abstract

The invention discloses a preparation method of a noctilucent luminous pigment. The noctilucent luminous pigment is prepared from the following raw materials in parts by weight: 20 to 30 parts of raw walnut oil, 20 to 30 parts of cooked walnut oil, 10 to 20 parts of a polyurethane resin, 30 to 40 parts of pigment powder, 5 to 25 parts of an additive, 25 to 50 parts of distilled water, 2 to 5 parts of aluminum powder, 1 to 7 parts of an antibacterial agent, 0.1 to 0.8 part of rare earth noctilucent fiber, 0.1 to 0.8 part of a nano aid, 0.02 to 0.08 part of talcum powder, 0.11 to 0.5 part of a dispersing agent and 3 to 6 parts of glycerol. According to the invention, the raw materials are proportionally stirred, filtered and mixed to finally obtain the pigment with the right concentration, wherein the production raw materials are moderate in proportion and dilution degree, so that light-emitting components cannot move in water during painting, non-uniformity of the light-emitting performance cannot be caused, and the color of the pigment cannot be affected by water; and after the pigment is manufactured, the noctilucent luminous pigment has the advantages of being good in luminous effect, sufficient in fineness, humor, firm in toughness, durable, high in color concentration, low in production cost, wide in application range, free of influence of water and good in luminous effect.

Description

technical field [0001] The invention relates to the technical field of pigments, more specifically, the invention relates to a preparation method of luminescent pigments. 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 blue, garcinia and purple extracted from shellfish in ancient Rome; [0003] It is 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. The development prospects of China's pigment industry are v...

Problems solved by technology

[0005] The luminous pigments used at home and abroad need to be dissolved in water when used, and their luminous components will also be dissolved in water. When painting, the luminous components are easy to move in the water, resulting in uneven luminous performance. At the same time, the color of the pigment will also be affected by water dilution. Influence, after the existing pigments on the market are produced, they are relatively insufficient in terms of luminous luminescence, insufficient fineness, humorous toughness is not strong, and the advantages of durability cannot be realized, and the color concentration is low, and the production cost is relatively high. Relatively limited, easily affected by water, poor luminous effect
