Problems solved by technology

But above-mentioned method exists: because acid treatment method uses a large amount of sulfuric acid, therefore can produce a large amount of acid sewage, thereby pollutes environment; Energy-consuming product process; solvent treatment method uses alcohol, benzene and other solvents in the production process, which is not only dangerous, but also needs to be recycled, and its residue will also cause a certain degree of pollution to the environment

Abstract

The invention discloses a preparation method of high energy-saving and environment-friendly type phthalocyanine green pigment in the field of preparation of organic pigment. The method is characterized by comprising the following specific steps: S1, copper phthalocyanine is pre-dissolved, 6-8 g of a catalyst is added, and the solution is heated to 100-120 DEG C for a chlorine introduction reaction; S2, a crude phthalocyanine green product is obtained after filtering; S3, then 5-7 g of a surfactant is added, stirring is performed sufficiently, an organic medium is removed by steam distillation,and a fine phthalocyanine green product is obtained after filtering and drying; S4, the fine phthalocyanine green product is mixed with 400-600 ml of water-based resin, the mixture is uniformly stirred, and the phthalocyanine green pigment is prepared. Power consumption for temperature increasing is reduced by increasing atmospheric pressure and reducing reaction temperature, meanwhile, system viscosity can be reduced, sufficient color development of the pigment is realized, color and luster are improved, acidic sewage is not discharged in the preparation process, and environmental pollutionis avoided.

Description

technical field [0001] The invention discloses a preparation method of a high-energy-saving and environment-friendly phthalocyanine green pigment, and specifically belongs to the technical field of organic pigment preparation. Background technique [0002] Phthalocyanine pigments are widely used in the fields of inks, coatings and plastics due to their superior heat resistance and weather resistance. The general methods of pigmentation include acid treatment, grinding and solvent treatment. The acid treatment method is to use the property that the crude product can be dissolved in concentrated sulfuric acid, dissolve it, and then precipitate crystals to obtain pigments with smaller particles; the grinding method is to use a ball mill, kneader, etc. to agglomerate with strong shear force and impact force. The particles are separated, and at the same time, in order to control the particles from agglomerating and obtain the required crystal form, it is necessary to add additive...
