Problems solved by technology

However, limited by the difference in production process and production equipment, the quality of the derivatives produced is quite different, which is not very ideal for application in the field of gravure ink, especially in the field of gravure NC ink. The product quality gap is relatively large.

Embodiment 1

[0055] Step 6: Preparation of Phthalocyanine Blue 15:4

[0056] Phthalocyanine blue 15:3 slurry 2300 kg (dried), add derivative A filter cake 184 kg (dried) and beat for 0.5 hours, add liquid caustic soda to adjust PH=7-7.5, heat up to 90°C and keep stirring for 2 hours, After the heat preservation is over, add water to cool down and filter through a filter press, wash with purified water to a conductivity of ≤100μs / cm, and dry to obtain an environmentally friendly and highly transparent phthalocyanine blue 15:4 product.

Embodiment 2

[0058] Step 6: Preparation of Phthalocyanine Blue 15:4

[0059] Phthalocyanine blue 15:3 slurry 2300 kg (dried), add 276 kg of derivative A filter cake (dried), beating for 0.5 hours, add liquid caustic soda to adjust PH=7-7.5, heat up to 90°C and keep stirring for 2 hours, After the heat preservation is over, add water to cool down and filter through a filter press, wash with purified water to a conductivity of ≤100μs / cm, and dry to obtain an environmentally friendly and highly transparent phthalocyanine blue 15:4 product.

Embodiment 3

[0061] Step 6: Preparation of Phthalocyanine Blue 15:4

[0062] Phthalocyanine blue 15:3 slurry 2300 kg (dried), add derivative B filter cake 184 kg (dried), beating for 0.5 hours, add liquid caustic soda to adjust PH=10-10.5, heat up to 90°C and keep stirring for 3 hours, The derivative B is fully adsorbed on the pigment molecules.

Abstract

The invention relates to a production method of gravure NC ink environment-friendly and highly transparent phthalocyanine blue 15:4, which belongs to the technical field of chemical synthesis. The present invention mainly includes the following steps: 1) synthesis of phthalocyanine blue 15:3; 2) synthesis of copper phthalocyanine derivatives; 3) production of phthalocyanine blue 15:4, three major steps in the production of phthalocyanine blue 15:4 step. The invention adds specific copper phthalocyanine derivatives in the production process, and then adds specific mixed ammonium salts to form sulfonate amine derivatives of copper phthalocyanine to prevent the re-aggregation of pigment particles, thereby improving the anti-crystallization and anti-crystallization of pigments. The flocculation performance ensures the application of the product in the downstream printing ink, thereby improving the quality of the pigment.

Description

technical field [0001] The invention belongs to the technical field of chemical synthesis, and relates to a method for manufacturing an environment-friendly highly transparent phthalocyanine blue 15:4, in particular to a method for manufacturing an intaglio NC ink environment-friendly and highly transparent phthalocyanine blue 15:4. Background technique [0002] Phthalocyanine blue is a blue organic pigment with excellent performance. It is widely used in many fields such as ink, paint, plastic color paste, culture and education. There are mainly 8 crystal forms such as α, β and ε. The crystal form is relatively the most stable, among which 15:4 is the most stable β crystal form phthalocyanine blue product. This crystal form product has excellent performance, good stability to heat and solvents, and presents a bright green light blue. [0003] The production of traditional phthalocyanine blue β-crystal form products is mainly obtained by kneading crude copper phthalocyanine,...
