Grinding equipment and method for high-performance phthalocyanine blue pigment

Abstract

The invention discloses high-performance phthalocyanine blue pigment grinding equipment and method.The high-performance phthalocyanine blue pigment grinding equipment comprises an operation platform used for pigment operation and processing and an outer cover used for preventing pigment from splashing in the processing process, a metal grinding table is fixedly installed at the top end of the interior of the operation platform, and a connecting ring is movably installed at the center of the interior of the metal grinding table; and two first connecting shafts are symmetrically installed on the side surface of the connecting ring, first scrapers are fixedly installed at the ends, away from the connecting ring, of the first connecting shafts, and a center rotating shaft is movably installed at the center of the connecting ring in a manner of penetrating through the operating platform. According to the high-performance phthalocyanine blue pigment grinding equipment and method, on one hand, when the pigment is used, coloring is facilitated, chromatic aberration is reduced, meanwhile, possible residues on an outer cover of the equipment and other positions can be effectively scraped off, waste in the production and processing process is greatly reduced, and finally, the production cost is reduced. The reaction effect and the dissolution speed can be accelerated.

Description

technical field [0001] The invention relates to the technical field of pigment processing, in particular to a rolling device and method for high-performance phthalocyanine blue pigments. Background technique [0002] Phthalocyanine blue BGSLA-61-02 metal-free phthalocyanine blue, is a brilliant green blue rod-shaped crystal. The density is 1.31~1.46g / cm3, and the specific surface area is 36~52m2 / g. Oil absorption 32~39g / l00g. Flocculation occurs in some vehicles. Insoluble in water, alcohol and hydrocarbons, soluble in concentrated sulfuric acid to form an olive-colored solution, and a blue suspension is precipitated after dilution. Phthalonitrile is heated at 125 ℃ in sodium pentoxide medium to form sodium phthalocyanine, which is dried and then treated with methanol at 10 ℃ to transform into metal-free phthalocyanine. For car paint, art pigment coloring. It is also used as some metal-free high-grade colorants; the existing phthalocyanine blue pigments have certain dra...

AI Technical Summary

Problems solved by technology

It is also used as some metal-free high-grade colorant varieties; existing phthalocyanine blue pigments have certain disadvantages when used, first of all, after the existing phthalocyanine blue pigments are produced, due to their crystal structure, resulting in The size difference of the finished products produced by it is too large, which is inconvenient for the user to use during the coloring process, and it is easy to cause color difference. At the same time, when adding other solvents or pigments for action, the reaction and dissolution speed of the two are too slow, which greatly affects the color of the product. Work efficiency has a certain impact in the process of use. Therefore, we propose a high-performance phthalocyanine blue pigment rolling equipment and method
