Product introduction
| This product is red and blue powder, the color light is less bright than the β-type phthalocyanine pigment. Excellent performance. In particular, in line with the performance requirements of paint, in the organic solvent does not produce increased crystallization, no flocculation, good storage stability. This product is brilliant blue powder. Bright color, strong coloring. Insoluble in water and organic solvents. Excellent performance, in the non-polar solvent does not produce increased crystallization, can be used in coatings. Green blue powder. Density 1.54~1.75g/cm3. It is an unstable α-type phthalocyanine dye, which has strong coloring power and excellent fastness performance, but it is easy to produce crystal increase and lose pigment performance in case of non-polar solvent, so it is not suitable for coating. This product is red light dark blue powder. It is an unstable α-phthalocyanine pigment with bright color and strong coloring power. Insoluble in water, ethanol and hydrocarbons. Dissolved in concentrated sulfuric acid for olive color, diluted blue precipitation. It has excellent fastness properties and is an irreplaceable blue variety in pigments. |
|
| Use | Used for coloring of paint, ink, plastic and rubber, etc. There are 160 kinds of commercial formulations of the pigment. Compared with other crystal forms of CuPc, the unstable α-crystal form of CuPc, A stronger red light is given, with higher coloration intensity and low cost characteristics. It is mainly used for offset printing ink packaging and metal decorative printing ink. Under normal conditions, it is stable to organic solvents, and the crystal form and color light change when stored in aromatic hydrocarbons, excellent light fastness, can withstand 200 ℃, further increase the temperature can be transformed into beta-type; Also applies to polyurethane foam and rubber; pure and bright color light makes it used for water-based coating and paper coloring and pigment printing paste. There are 252 kinds of commercial dosage forms of the pigment, which are of β-CuPc type, pure green, light blue or green |
Introduction
Phthalocyanine blue is bright blue crystal and decomposes when heated. Generate toxic fumes. Crude phthalocyanine blue can be made into pigment by appropriate method, and the index number of pigment is C. I.P.B. 15.
crystal form
phthalocyanine blue has a variety of crystal forms, namely a, 0, y, etc., relative color light, of which a and, type partial red light, type 3 partial green light. 0 is stable crystal form, others are metastable crystal form. Type a and type 0 are used as pigments.
application
Phthalocyanine blue is used in inks, coatings and plastics due to its superior heat resistance and climate fastness.
Production process
A new production process of phthalocyanine blue pigment, which is characterized in that: phthalocyanine blue is subjected to acid treatment and grinding treatment, the acid treatment is carried out before grinding, or during grinding, and the temperature of the acid treatment is 10-80 ℃, The time is 2-30 hours; after acid treatment, the obtained acid-soluble mixture is added to water and stirred, the water temperature is 0-90 ℃, and the quality of the water is 3-20 times the quality of the acid; by adjusting the concentration of acid, the temperature of acid treatment, and the temperature of precipitation, the crystallization is transformed into the crystal form required for phthalocyanine blue pigment.
Production method
P> there are many synthesis methods for this product. baking method and solvent method are commonly used in industry. solvent method is taken as an example.
procedure
2776kg of trichlorobenzene, 1200kg of phthalic anhydride and 1000kg of urea are added into the kettle for condensation, the temperature is raised to 160 ℃, the temperature is kept for 2 hours, trichlorobenzene, 850kg of urea and 230kg of cuprous chloride are added for the sixth time, the temperature is increased, and the temperature is kept for a certain period of time. For the third time, 867kg of trichlorobenzene and 13.4kg of ammonium molybdate were added. After addition, the temperature was gradually increased to about 200 ℃ for heat preservation reaction. Then move into the distillation pot to add liquid alkali and steam out the solvent. Rinse with water, continue to steam, and dry the materials with a film dryer to obtain 1250kg of crude phthalocyanine blue.
refining 135kg of refined products are added to 850kg 98% sulfuric acid for dissolution, kept at 40 ℃, then 17kg of xylene is added, the temperature is increased to 70 ℃, the temperature is gradually decreased to 24 ℃, diluted in water, stood still for 3 hours, and the upper waste liquid is absorbed. after repeated for three times, the waste liquid is neutralized with 30% sodium hydroxide until pH = 8~9, and boiled with direct steam for half an hour after stirring, washed, dried and ground to obtain 118kg of refined phthalocyanine blue.
