In ancient Egypt, artisans beat and stretched gold into gold leaf, and put it on stones, bones, etc., to make crafts or sacrifices. In the above process, the edges of the gold foil are easy to break and fall off, resulting in some gold fragments. Later, craftsmen discovered that mixing these debris with natural oils and coating them on these objects can also achieve a decorative effect. Soon these discoveries and technologies were transferred to silver. Over time, this technology was also transferred to ancient India, China, and later to Europe. With the development of metal smelting technology, metallic aluminum appeared. It was found that aluminum is relatively soft in texture and has good ductility, that is, it can be rolled into flakes by pressure. This is a very important prerequisite for the production of aluminum pigments.

During the Renaissance in Europe, aluminum pigments were produced by mechanical ramming. Even using a rigid hammer, hammer the aluminum block on the steel plate into a sheet. During processing, grease is used as a lubricant. However, the efficiency of this process is not high, there is a danger of explosion, and the performance of the product is not satisfactory.

In 1892, the German Schlenk Company began to produce aluminum powder.

In 1910, Alcoa began producing aluminum pigments for coatings.

In 1930, Professor E.J.HALL of Columbia University in the United States invented the wet grinding process for the production of aluminum pigments. The method is to use a roller ball mill to add a certain amount of steel balls, granular aluminum, solvents and fatty acids. Turn on the ball mill and grind at a certain speed. Using the impact and shear force generated by the movement of the steel ball, the aluminum powder is first stretched into flakes, and then crushed to a certain degree of fineness (particle size). Due to the presence of solvents, aluminum is isolated from contact with oxygen in the air, thereby playing a protective role and avoiding explosion hazards. At the same time, the output and quality of products have been greatly improved. Therefore, wet ball milling has gradually become a metal pigment. The main preparation process. Up to now, the world's major metal pigment manufacturers have adopted this process.

In 1934, since the Chrysler Automobile Company of the United States first used aluminum pigments in automobile coatings, the technology and output of metallic pigments have been greatly improved. At present, with the advancement of metallic pigment technology, more than 50% of automobiles in the world are painted with metallic flash paint. Among them, more than 75% in the United States and more than 50% in Japan and Europe contain aluminum pigments. For household and office appliances such as televisions, computers, refrigerators, and mobile phones, aluminum pigments are used in a larger proportion and become a trend. From magnificent ancient palaces to modern high-rise buildings, from cars on the streets to people’s daily necessities, products with metallic luster can be seen everywhere, but many products with metallic luster are not real metal products. The emergence of metallic paint (aluminum pigment occupies a large proportion of metallic pigments) has made up for the lack of people's pursuit of metallic luster, which not only reduces the cost, but also meets the demand. Solvent-based metallic paint has excellent luster and excellent weather resistance. , Corrosion resistance, widely used in industries such as automobiles, motorcycles, bicycles, ships, toys, home appliances, computers and mobile phones. Therefore, under the impetus of the market, the development of aluminum pigments is unstoppable, and the market prospect is very broad.
