    Surface Treatment of Organic Pigment Phthalocyanine Green
    Time:2019-04-23 10:07:18


    Phthalocyanine green, as an organic pigments, has the advantages of convenient manufacture and excellent performance. Pigments are colored by tiny fine particles dispersed in or attached to the colored substance by means of a medium. Therefore, the characteristics of pigments are of great significance to the pigments themselves.


    The surface treatments of phthalocyanine green pigments are as follows:

    1. Surface treatment of rosin soap: through chlorination reaction, the process needs to add 5% - 30% rosin soap solution with pigment content. The main function is to prevent the aggregation of pigment particles in the drying process. Calcium rosinate forms "isolation" between phthalocyanine green pigment particles. At the same time, because calcium rosinate itself is a component of mineral oil-type linking materials in lithographic and embossing inks, the phthalocyanine green ink treated by this method will be better.


    2. Surface treatment of amines: alkaline amines enter directly into the pigmented phthalocyanine green pigments in acidic environment, and then adjust the PH value of the slurry with alkali solution, so that amines can be transformed into insoluble compounds and adsorbed on the surface of the pigment particles.


    3. Surface treatment of synthetic resins: it can be achieved together in the process of pigmentation, or can be mixed with resins and appropriate solvents; surface treatment of phthalocyanine green with synthetic resins can be up to 50%. After treatment with high content resins, it has actually become a kind of pigment preparation, mainly used for pigmentation of masterbatches and plastic products.
