Problems solved by technology

Organic pigments are generally taken from plants and marine animals, such as madder blue, garcinia, and purple extracted from shellfish in ancient Rome. At present, many chemical pigments are widely used, but when they are used, the brightness is not high. Very high, some special occasions need to use high-brightness pigments, and now many high-brightness pigments will fade due to insufficient strength after long-term use, and the brightness will decrease, so a chemically strong brightness type is designed Pigment formula

Abstract

The invention discloses a formula of chemical pigment with enhanced brightness. The chemical pigment is prepared from raw materials in parts by weight as follows: 80-100 parts of a priming paint solvent, 40-60 parts of aluminium stearate, 10-15 parts of a dispersing agent, 10-15 parts of a color stabilizer, 5-10 parts of colloids, 2-10 parts of a dryer, 8-14 parts of modified fluorocarbon resin, 6-8 parts of water-soluble resin, 6-10 parts of butyl stearate and 2-4 parts of a cosolvent. The produced pigment has higher strength and can enhance brightness very well, so that the pigment can be used for a long time, conditions of fading and dimming caused by oxidization are avoided, the service life of the pigment is greatly prolonged, and the formula is worthy of popularization.

Description

technical field [0001] The invention relates to the technical field of production of chemical brightness pigments, in particular to a formula of chemical high brightness pigments. Background technique [0002] Pigment is 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 taken from plants and marine animals, such as madder blue, gamboge, and purple extracted from shellfish in ancient Rome. At present, many chemical pigments are widely used, but when they are used, the brightness is not high. Very high, some specific occasions need to use high-brightness pigments, now many high-brightness pigments will fade due to insufficient strength after long-term use, and the brightn...
