Embodiment 1

[0021] In a 5-liter vertical vibrating mill, add 1000 parts of crude phthalocyanine blue at a temperature of 30 degrees. Add 15 parts of sodium chloride and 150 parts of rosin soap during stirring, keep the temperature at 40-45° C., stir for 2 hours, then add 30 parts of 98% sulfuric acid to carry out pigment transformation. Suck out the material, remove iron through a dry iron remover, and pulverize to obtain phthalocyanine blue powder.

Embodiment 2

[0023] In a 15-liter horizontal vibrating mill, mix 5000 parts of crude phthalocyanine blue, 30 parts of sodium chloride, and 400 parts of rosin soap at a temperature of 35 degrees. Continuously put in and vibrate and stir, keep the temperature at 60-85°C, vibrate and stir for 2 hours, then add 100 parts of 98% sulfuric acid to carry out pigment transformation. Suck out the material, remove iron through a dry iron remover, and pulverize to obtain phthalocyanine blue powder.

Embodiment 3

Abstract

A preparation method of a novel phthalocyanine blue organic pigment comprises the following steps of: grinding a crude product phthalocyanine blue, adding an inorganic salt grinding aid and a surface conditioning agent during the grinding process, carrying out acid treatment and solvent transition on the ground materials, sucking out the materials, removing iron, and crushing to obtain the novel phthalocyanine blue organic pigment. The phthalocyanine blue organic pigment prepared by the method has excellent heat resistance and weatherability fastness; the obtained pigment has brilliant color, high tinting strength and good dispersibility; and the product is suitable for high-grade printing ink, paint and plastic coloring.

Description

technical field [0001] The invention relates to a method for preparing a blue organic pigment, in particular to a method for preparing a novel phthalocyanine blue organic pigment. Background technique [0002] Phthalocyanine pigments are widely used in the fields of inks, coatings and plastics due to their superior heat resistance and weather fastness. The general pigmentation methods include acid treatment, grinding, solvent treatment and so on. The purpose of pigmentation is to change the crystal form to stable α or B type; the second is to control the particle size distribution and particle shape; the third is to perform surface treatment to improve the dispersion and applicability in specific application media . Through the above adjustments, a product with bright color, high tinting strength, good dispersibility, and high fastness properties such as weather resistance and heat resistance can be obtained. [0003] The acid-soluble method is to use the property that th...
