Product introduction of high pigment carbon black

English name: high color black

1. Pigment properties

Shandong Caizhiyuan Pigment Technology: High-pigment carbon black is a high-temperature oxidation product with a blue hue. It has excellent properties such as high blackness, strong tinting strength, good fluidity, easy dispersion, migration resistance, UV resistance and oxidation resistance.

The blackness of high-pigment carbon black is less than or equal to 16, the tinting strength% is greater than or equal to 130, the oil absorption (ml/g) is 1.0, the volatile matter (% at 950°C) is 7.0, the moisture (% ≤) is 5.0, and the pH value is 2.5. The flowability (35°C mm) was 22 and the sieve residue was 50.

High-pigment carbon black has excellent dispersion performance, low oil absorption, excellent weather resistance, acid and alkali resistance.

2. Introduction of carbon black blackness

The darker the carbon black, the higher its acidity. The pH value is between 2.5 and 4.5, and the adsorption capacity is higher. The pH value of ordinary carbon black is almost neutral, so its adsorption capacity is not obvious. Because the adsorption capacity of carbon black has a special effect on the dryness of coatings, the drying rate of coatings often decreases because of the adsorption of the drier in the paint.

When the PH value of carbon black is below 4, the greater its acidity, the greater the adsorption capacity of the drier, and the more obvious the effect on the anti-drying performance. The anti-drying effect of carbon black is not manifested immediately after the paint is made, but only after a period of time after the drier is completely or partially adsorbed (storage period). Therefore, when designing the paint, it is necessary to consider appropriately increasing the amount of drier.

3. The importance of carbon black dispersion

Pigments must be dispersed into fine particles that meet optical properties during application. Carbon black is one of the most difficult to disperse pigments in all pigments. Therefore, the quality of carbon black dispersion will directly affect the blackness, hue and hiding ability of carbon black. , which directly affects the user's use effect.

4. The dispersion process of carbon black is mainly affected by three factors

A. The essential characteristics of carbon black: The original particle size, structure and various groups on the surface of carbon black will have a great influence on the dispersion. Under normal circumstances, the original particle size of carbon black is small, the structure is low, and the volatile content is low, and it is difficult to disperse, and vice versa is relatively easy.

B. carbon black use carrier: The properties of the base material, solvent and resin will significantly affect the final dispersion of carbon black, especially the selection of Resin for carbon black.

C. Dispersion equipment for carbon black: The dispersion effect of different dispersion equipment under the same conditions is very different. The selection of the correct dispersion equipment is something that engineers must pay attention to.

5. Application areas

High-pigment carbon black is mainly used for the coloring of automotive paints, powder coatings, PVC cables, inks, plastics, leather colorants, cathodic electrophoretic paints, rubber and art pigments.
