Alkali Resistance of Iron Oxide Pigment

Iron Oxide Pigment is a pigment with good dispersibility, and excellent light and weather resistance. Iron oxide pigments mainly refer to iron oxide red, iron yellow, iron black and iron brown coloring pigments based on iron oxides, among which iron oxide red is the main (accounting for about 50% of iron oxide pigments), Mica iron oxide used as an anti-rust pigment and magnetic iron oxide used as magnetic recording material also belong to the category of iron oxide pigment.

Iron oxide pigment is the second largest inorganic pigment after titanium dioxide and the largest color inorganic pigment. Of all the iron oxide pigments consumed, more than 70% are prepared by chemical synthesis methods, which are called synthetic iron oxides. Synthetic iron oxide is widely used in building materials, coatings, and plastics due to its high synthetic purity, uniform particle size, wide chromatogram, multiple colors, low cost, non-toxicity, excellent coloring and application properties, and ultraviolet absorption properties. , electronics, tobacco, medicine, rubber, ceramics, ink, magnetic materials, paper and other fields.

1. Iron oxide red Iron oxide red is yellow, red and blue phase red iron oxide powder, which has excellent light resistance and high-temperature resistance, and is resistant to atmospheric influence, foul gas and all alkalis. It will only gradually dissolve when heated in concentrated acid. 2. Iron oxide yellow The color of iron oxide yellow is bright and pure, ranging from lemon hue to orange hue. It has excellent light resistance and high temperature resistance, and is resistant to atmospheric influence, foul gas, and all alkalis. 3. Iron oxide black Iron oxide black is a blue-light black powder. The blackness of the naked eye is similar to that of carbon black. The texture is fine, insoluble in water and alcohol, and soluble in concentrated acid and hot acid. Magnetic, high tinting power and hiding power. Iron oxide black has good weather resistance, light resistance, atmospheric resistance, durability, no water permeability and oil permeability. It is very stable in general organic solvents, has good alkali resistance, and is heat-resistant to 180 °C. It is easily oxidized when heated at high temperature and turns into red iron oxide. 4. Iron oxide green Iron oxide green (composite green) has good dispersibility, bright color, strong weather resistance, good compatibility with other components in the application system, and can enhance the anti-rust and anti-ultraviolet properties of the paint.
