[0008] However, both of the above two methods have the phenomenon that a large amount of waste acid cannot be processed, causing great pollution to the environment, and at the same time seriously restricting the output of the product; at the same time, because the product is an α-crystalline product, the heat resistance, anti-flocculation, and anti-crystallization of the product are caused. The performance is relatively poor and cannot be used in high-grade baking coatings

Embodiment 1
[0087] A pigment composition containing phthalocyanine blue 15:2, which is made up of the following components:
[0089] Wherein, the preparation method of described phthalocyanine blue 15:0 is as follows:
[0090] S11 copper phthalocyanine pretreatment
[0091] Under vacuum conditions, mix the crude copper phthalocyanine and sulfuric acid solution with a mass concentration of 5% at a weight ratio of 1:8 for beating for 1 hour, then stir at 95°C for 6 hours, add water to cool down to 70°C, wash with water in a filter press until neutral, and dry Obtain pure copper phthalocyanine;
[0092] copper phthalocyanine activation
[0093] The pure copper phthalocyanine was mixed with anhydrous sodium sulfate at a weight ratio of 5:1 and ground in a ball mill at a grinding temperature of 70°C for 12 hours;
[0094] S12 Add activated copper ...
Embodiment 2
[0109] A kind of pigment composition that contains phthalocyanine blue 15:2, and its difference with embodiment 1 is:

Abstract
The invention belongs to the technical filed of phthalocyanine blue pigment preparation, and particularly relates to a pigment composition containing phthalocyanine blue 15:2 and a preparation methodthereof. The pigment composition is prepared from the following ingredients including phthalocyanine blue 15:0, copper phthalocyanine chloro derivatives and copper phthalocyanine sulfonation derivatives. According to the preparation method, the copper phthalocyanine chloro derivatives, the phthalocyanine blue 15:0 and the copper phthalocyanine sulfonation derivatives are subjected to mixing and pulping and are then subjected to heat treatment at 78 to 85 DEG C; water is added for temperature lowering; press filtering, water washing and drying are performed; a solid is obtained through filtering; a finished product is obtained. The pigment composition and the preparation method provided by the invention achieve the goals of crystallization resistance, color fastness, flocculation resistanceand system viscosity reduction. The prepared phthalocyanine blue pigment has the advantages of high transparency, high coloring intensity, high flowability, high heat resistance and high weather resistance, and can be widely applicable to the fields of printing, paint, ink and weaving.
Description
technical field [0001] The invention belongs to the technical field of preparation of phthalocyanine blue pigments, and in particular relates to a pigment composition containing phthalocyanine blue 15:2 and a preparation method thereof. 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. [0003] Among them, phthalocyanine blue 15:2 is a stable α-crystal phthalocyanine blue product, which has the characteristics of bright color and strong tinting strength, and is widely used in plastics, water-based color pastes, printing color pastes, water-based inks and other fields. [0004] The production of traditional phthalocyanine blue α-crystal products is mainly produced by the acid-dissolving process of crude copper phthalocyanine and the acid swelling of activated copper phthaloc...
