Name | Indigo green |
Synonyms | Indigo green |
Physical and Chemical Properties | Dark green powder, bright color, strong coloring, with superior light resistance, heat resistance, acid resistance, alkali resistance, solvent resistance. |
production process is prepared by suspending crude phthalocyanine blue in a eutectic mixture of ferric chloride and aluminum chloride, using copper chloride as a catalyst, reacting with chlorine at 180~200 ℃, and then post-processing with inert solvent, etc.
varieties and applications phthalocyanine green is widely used in printing ink, iron printing ink, paint, spray paint, plastic, rubber, paint printing pulp and raw pulp coloring of synthetic fibers. If used to prepare coatings, studies have reported a formulation of a flash coating, which is made from the following raw materials: aluminum powder, resin, xylene, phthalocyanine green, phthalocyanine blue and leveling agent, where the mass percentage of each component is:
aluminum powder 5 ~ 8%
Resin 56 ~ 62%
xylene 9 ~ 11%
phthalocyanine green 14 ~ 18%
phthalocyanine orchid 8 ~ 10%
P> leveling agent 0.08 ~ 0.12% this kind of paint is low in price, and the decorated wall surface can form an elegant and gorgeous green effect with fresh style. at night or in the dark, the green surface can emit soft light. under the irradiation of other colors of lights, the green surface can change color and emit light, and at the same time, it also has the characteristics of scrubbing resistance, no fading, etc, can be used for wall hand-painted, paint finishes and other decorative styles of special embellishment. Another example is used to prepare a green ink for printing on PP synthetic paper, comprising an acrylic resin 40%, a phthalocyanine green 10%, a filler 12%, a dispersant 4%, an adhesion promoter 12%, and an organic solvent 18%. The process steps are: 1) according to the ratio of acrylic resin, phthalocyanine green, filler, dispersant, and organic solvent mixed and fully stirred. The characteristic of this ink is that the formula adds an adhesion promoter, which greatly improves the adhesion of the ink on the material.
