Embodiment 1

[0056] 18.5 parts of chlorinated copper phthalocyanine (average number of chlorine substituents: 0.5) and 1.5 parts of phthalimidemethyl copper phthalocyanine were dissolved in 180 parts of sulfuric acid with a mass fraction of 95% to prepare ejector. Sulfuric acid slurry is obtained by aspirating with (resin aspirator) while mixing with hot water. The sulfuric acid slurry was aged at 70°C for 1 hour, filtered, and washed repeatedly with water until neutral. Then, a solution obtained by emulsifying xylene with an emulsifier was added to the pigment slurry, and xylene was distilled off, followed by filtration, washing with water, and drying. The dried product was pulverized to obtain a copper chloride phthalocyanine pigment composition.

Embodiment 2

[0058] 45 parts of copper phthalocyanine chloride (the average number of chlorine substituents is 0.5) 18.5 parts, 45 parts of copper phthalocyanine dimethyl propyl sulfamate This solution was dissolved in 180 parts of 95% sulfuric acid at 95 ° C, while using While being sucked by a resin aspirator, it is mixed with warm water to obtain a sulfuric acid slurry. The sulfuric acid slurry was aged at 70°C for 1 hour, filtered, and washed repeatedly with water until neutral. After that, a solution obtained by emulsifying xylene with an emulsifier was added to the pigment slurry, and xylene was distilled off, followed by filtration, washing with water, and drying. The dried product was pulverized to obtain a copper chloride phthalocyanine pigment composition.

Embodiment 3

[0060] Add 18.5 parts of copper phthalocyanine chloride (average number of chlorine substituents 0.5) and 1.5 parts of copper phthalocyanine sulfonate dimethyl diallyl ammonium salt (number of sulfonic acid substituents 1.0) at 45 °C, and add 95% sulfuric acid . Dissolve it in 180 parts. In the primary reagent manufactured, and mixed with warm water while suctioning with a resin aspirator to obtain a sulfuric acid slurry. The sulfuric acid slurry was aged at 70°C for 1 hour, filtered, and washed repeatedly with water until neutral. After that, a solution obtained by emulsifying xylene with an emulsifier was added to the pigment slurry, and xylene was distilled off, followed by filtration, washing with water, and drying. The dried product was pulverized to obtain a copper chloride phthalocyanine pigment composition.

Abstract

The invention belongs to the field of chemical pigments. In the prior art, the bronze performance of a copper peptide nitrile pigment and a composition thereof used on the plastic surface cannot be effectively reduced on the premise of ensuring the color fastness, the light resistance, the heat resistance, the corrosion resistance and the like of the pigment. In order to solve the problem, the invention provides a copper chloride and phthalocyanine pigment composition for coloring non-bronze plastics, and a preparation method thereof.

Description

technical field [0001] The invention belongs to the field of chemical pigments, and in particular relates to a copper chloride phthalocyanine pigment composition and a preparation method for non-bronze plastic coloring. Background technique [0002] Phthalocyanine pigment is a water-insoluble organic compound containing phthalocyanine molecules in its molecular structure. As a chromophore conjugated system, phthalocyanine is a cyclic alkene structure that combines four indoles to form a polycyclic molecule and contains 18 electrons. . As a kind of blue pigment derived from phthalocyanine structure, phthalocyanine pigment has bright color, strong tinting strength, high fastness, high light resistance, high weather resistance, high heat resistance, good dispersion, strong hiding power and durability , Acid and alkali corrosion resistance, fine particles, easy to diffuse, easy to process and grind. In addition, phthalocyanine pigments are polymorphic compounds, among which α ...
