Properties and Application of Copper Chrome Black
Inorganic pigments can be divided into natural inorganic pigments and synthetic pigments according to the production method. According to the function, it can be divided into four types: antirust pigments, body pigments, special pigments and coloring pigments. According to the chemical structure, it can be divided into iron series, chromium series, lead series, zinc series, metal series, phosphate series, molybdate series, borate series, etc. Inorganic coloring pigments can be divided into two categories: color pigments and achromatic pigments according to their color. The following introduces a common inorganic pigment - copper chrome black.
Copper chrome black is a blue-phase metal oxide mixed-phase black pigment with extremely deep blackness. It is synthesized by high-temperature solid-state reaction after mixing various metal oxides. It has pure color, environmental protection, non-toxicity, high temperature resistance, acid and alkali resistance. , solvent resistance, non-migration, easy dispersion, chemical inertness and chemical stability.
Because of its excellent properties, copper chrome black is widely used in various coatings (such as exterior wall coatings, architectural coatings, automotive coatings, road marking coatings, water-based coatings, anti-ultraviolet coatings, industrial coatings such as fluorocarbon coatings, powder coatings, etc. Coatings), color inks, high temperature resistant plastics (such as engineering plastics, masterbatches, etc.), building materials, colored glass, ceramics, enamel and other fields.
C. Other uses:
Copper chrome black pigment is environmentally safe and has excellent chemical stability. It can also be used in boilers, enamel cookware, food packaging, and toy industries.
