Pigment blue 29, also known as ultramarine blue, is a multi-component inorganic pigment (sulfur-containing sodium aluminosilicate), also known as cloud blue or ocean blue. Ultramarine is insoluble in water and is resistant to alkali, weather resistance and light resistance. However, it changes color when exposed to acid and has weak tinting and hiding power. Pigment blue 29 has a wide range of uses and is commonly used in coatings, plastics, resins, inks, construction, paper, detergents, painting pigments, cosmetics and other industries.
At present, many manufacturers at home and abroad use kaolin to produce ultramarine series pigments, but the use of halloysite to prepare ultramarine pigments has not yet been reported. Halloysite is an octahedral layered silicate mineral with a 1:1 structural layer and belongs to the kaolinite group. Halloysite clay is also an important non-metallic mineral raw material. Halloysite clay, like other clay minerals, has been utilized by people for a long time. Especially since this century, many experts at home and abroad have studied it and made great progress. In terms of its development and utilization, it has been involved in the fields of electronic components, optical glass, glazes, high-voltage electrical porcelain, Japanese Ceramics, building ceramics, industrial fillers, chemical raw materials, etc.
