Abstract
The invention discloses a phthalocyanine blue preparation method. The phthalocyanine blue comprise, by mass, 30-50 parts of crude copper phthalocyanine, 80-120 parts of calcium chloride, 10-30 parts of industrial salt and 0.1-0.2 parts of xylene. The preparation method comprises material mixing, acidification, alkali washing, cleaning, drying and packaging. The crude copper phthalocyanine, calcium chloride, industrial salt and xylene are fully mixed and the mixture is acidified and alkaline-washed so that impurities are removed and a semi-finished product is obtained. The phthalocyanine blue preparation method stabilizes physical properties, prevents product fading, has simple processes, is convenient for operation and has a low cost.
Description
Technical field
The present invention relates to technical field of pigment preparation, the preparation method being specifically related to a kind of phthalocyanine blue.
Background technology
Phthalocyanine blue is the organic pigment of a kind of function admirable, can be widely used in automobile coating, art painting painted, be also used as some metal-free high-grade coloring agent kinds.Some producer of domestic enterprise can produce high-quality phthalocyanine blue crude product, and has section port, but most producers not only quality has much room for improvement, and costly, runs business into particular one but without crude product really being done essence simultaneously, and the derivative degree of depth developed is inadequate.The preparation method developing a kind of phthalocyanine blue for this.
Summary of the invention
The preparation method that it is an object of the invention to provide a kind of phthalocyanine blue, this preparation method is simple, and easy to operate, cost is low.
For achieving the above object, the technical solution used in the present invention is: the preparation method of a kind of phthalocyanine blue, following mass parts become to be grouped into: raw copper phthalocyanine 30-50 part, calcium chloride 80-120 part, Nacl 10-30 part, dimethylbenzene 0.1-0.2 part.
Further, the preparation process of described phthalocyanine blue is as follows:
1) mixing: by raw copper phthalocyanine, calcium chloride, Nacl, dimethylbenzene by said ratio mixing, being then fed into reactor and carry out hybrid reaction, reaction temperature is 20-25 DEG C, and the response time is 2-3h；
2) acidifying: adding the hydrochloric acid that mass concentration is 15% in mixture upon mixing and react, the response time is 3-4h, and reaction temperature is 20-25 DEG C；
3) alkali cleaning: adding the sodium hydroxide that mass concentration is 20% in the mixture after acidifying and carry out alkali cleaning reaction, the response time is 3-4h, and reaction temperature is 20-25 DEG C；
4) clean: being sent in pressure filter by the mixed material after alkali cleaning and be carried out with water, wherein mixed material is stayed in pressure filter, and waste water is discharged；
5) dry: the material staying in pressure filter after cleaning is taken out, then carries out nature drying and processing；
6) packaging: the material after drying is sent into pulverizing process in flour mill, then packs by specification.
Further, described step 1) in time be 2-2.5h.
Beneficial effect: the present invention adopts raw copper phthalocyanine, calcium chloride, Nacl, dimethylbenzene to be sufficiently mixed, then pass through acidifying, alkali cleaning obtains semi-finished product, adopt acidifying, alkali cleaning the two step can remove wherein impurity, and stabilize its physical property, and it is also prevented from product to fade, this preparation method technological process is simple, and easy to operate, cost is low.
