Problems solved by technology

[0006] It can be seen from the brief description of the above method that the traditional phthalocyanine blue 15:4 production process has a long process, consumes a large amount of raw materials, consumes a lot of power, and produces a large amount of pollutants that have an important impact on the environment. Serious, and form a certain conflict with the national environmental protection policy

Embodiment 1

[0035] Example 1: Add 1000kg of crude copper phthalocyanine with purity ≥98.5% and free copper content ≤1000ppm to a 10000L horizontal ball mill, and add 30kg of copper phthalocyanine derivative shown in the raw material selection, turn on the ball mill for ball milling, and pass Adjust the temperature of the materials in the cooling water control machine at 125±2°C and ball mill for 12 hours to obtain a ball milled product containing 38% α crystal form. The ball milled product was passed through a magnetic filter to remove the iron produced during the ball milling, and the product was collected to obtain a phthalocyanine blue 15:4, 1# sample with an average particle size of less than 1 μm.

Embodiment 2

[0036] Example 2: Add 1000kg of crude copper phthalocyanine with purity ≥98.5% and free copper content ≤1000ppm to a 10000L horizontal ball mill, and add 30kg of copper phthalocyanine derivative shown in the raw material selection, turn on the ball mill for ball milling, and pass Adjust the temperature of the materials in the cooling water control machine at 135±2°C, and ball mill for 12 hours to obtain a ball milled product containing 35% of α crystal form. The ball milled product was passed through a magnetic filter to remove the iron produced during ball milling, and the product was collected to obtain phthalocyanine blue 15:4, 2# sample. The average particle size of the pigment was less than 1 μm.

Embodiment 3

[0037] Example 3: 1000kg of crude copper phthalocyanine with purity ≥98.5% and free copper content ≤1000ppm is added to a 10000L horizontal ball mill, and 30kg of copper phthalocyanine derivative shown in the raw material selection is added, and the ball mill is turned on for ball milling and passed Adjust the temperature of the material in the cooling water control machine at 150±2°C and ball mill for 12 hours to obtain a ball milled product containing 31% α crystal form. The ball milled product was passed through a magnetic filter to remove the iron produced during the ball milling, and the product was collected to obtain phthalocyanine blue 15:4, 3# sample. The average particle size of the pigment was less than 1 μm.

Abstract

The invention discloses a production method of phthalocyanine blue 15:4 for toluene ink, wherein crude copper phthalocyanine has the purity of over 98.5% and the free copper of less than 1000ppm, and in an expression of a copper phthalocyanine derivative, m arranges between 0.2 to 1.8, n arranges between 0.5 to 0.9; the crude copper phthalocyanine is placed into grinding equipment to be ball milled, then a magnetic filter is utilized to separate iron generated during the ball milling process, and phthalocyanine blue 15:4 is prepared. The method has the notable characteristics of short production process, low cost and small influence on environment; and compared with the pigment prepared by the traditional method, the phthalocyanine blue 15:4 pigment for the toluene ink, which is produced by the method, is the same with the color and the color intensity of the toluene ink, and obviously improves the viscosity, luster and transparency.

Description

Technical field [0001] The invention belongs to the technical field of preparation of phthalocyanine blue pigments, and particularly relates to a method for producing phthalocyanine blue 15:4 for toluene ink. Background technique [0002] Phthalocyanine blue is a functional pigment, mainly including P.B15, P.B15:1, P.B15:2, P.B15:3, P.B15:4, P.B15:6 and aluminum phthalocyanine Several series. With pure, bright and strong red color, anti-crystallization, anti-flocculation, heat-resistant stability, mainly used in coatings, plastics, inks, textile masterbatch, printing paste and other industries. The pigment belongs to a heterogeneous compound, based on the difference of the crystal lattice structure, has a variety of crystal forms, such as α-crystal form (phthalocyanine blue 15, 15:1, 15:2), β-type crystal form (phthalocyanine blue 15:3, 15:4); γ crystal form; ε crystal form (phthalocyanine blue 15:6); δ crystal form five crystal forms of phthalocyanine blue. They each show dif...
