Embodiment 1

[0017] (1) Take respectively 16 parts of Pigment Violet 19, 4 parts of cocamidopropyl dimethyl tertiary amine, 9 parts of sodium alginate and 8 parts of decaglycerol tetraoleate by weight. The ingredients are stirred at room temperature, and after stirring evenly, it becomes the mixture A, which is set aside;

[0018] (2) Get 6 parts of methyl glucose polyoxypropylene ethers, 3 parts of acetylated lanolin alcohols, 5 parts of erucamide propyl betaines, 7 parts of water-based polyurethanes, and 260 parts of water respectively by weight, and put the above-mentioned ingredients in Stir at room temperature until uniform, it is mixture B, set aside;

[0019] (3) Mix mixture A and mixture B until uniform at a temperature of 40°C, and then shear the mixture with a shearing device at a shearing speed of 7000 rpm and a shearing time of 10 minutes. After shearing, It is pigment violet 19 dispersion.

Embodiment 2

[0021] (1) Take respectively 10 parts of Pigment Violet 19, 10 parts of cocamidopropyl dimethyl tertiary amine, 3 parts of sodium alginate, and 4 parts of decaglycerol tetraoleate by weight. The ingredients are stirred at room temperature, and after stirring evenly, it becomes the mixture A, which is set aside;

[0022] (2) Get 10 parts of methyl glucose polyoxypropylene ether, 7 parts of acetylated lanolin alcohol, 2 parts of erucamide propyl betaine, 4 parts of water-based polyurethane, and 140 parts of water respectively by weight, and put the above-mentioned ingredients in Stir at room temperature until uniform, it is mixture B, set aside;

[0023] (3) Mix mixture A and mixture B until uniform at a temperature of 50°C, then shear the mixture with a shearing device, the shearing speed is 4000rpm, and the shearing time is 60min. After shearing, It is pigment violet 19 dispersion.

Embodiment 3

[0025] (1) Take respectively 15 parts of Pigment Violet 19, 6 parts of cocamidopropyl dimethyl tertiary amine, 8 parts of sodium alginate and 7 parts of decaglycerol tetraoleate by weight. The ingredients are stirred at room temperature, and after stirring evenly, it becomes the mixture A, which is set aside;

[0026] (2) Get 9 parts of methyl glucose polyoxypropylene ethers, 4 parts of acetylated lanolin alcohols, 3 parts of erucamide propyl betaines, 6 parts of water-based polyurethanes, and 170 parts of water respectively by weight, and put the above-mentioned ingredients in Stir at room temperature until uniform, it is mixture B, set aside;

[0027] (3) Mix mixture A and mixture B at a temperature of 40°C until uniform, then shear the mixture with a shearing device, the shearing speed is 5000rpm, and the shearing time is 30min. After shearing, It is pigment violet 19 dispersion.

Abstract

The invention discloses pigment violet 19 dispersion and a preparation method thereof. The preparation method comprises the following steps: 1, taking 10-16 parts by weight of pigment violet 19, 4-10 parts by weight of cocamidopopyl dimethylamine, 3-9 parts by weight of sodium alginate and 4-8 parts by weight of decaglyceryl tetraoleate, stirring at room temperature to obtain a mixture A for standby application; 2, taking 6-10 parts by weight of methylglucamine polyoxypropylene ether, 3-7 parts by weight of acetylated lanolin alcohol, 2-5 parts by weight of erucylamide propyl betaine, 4-7 parts by weight of waterborne polyurethane and 140-260 parts by weight of water, stirring at room temperature to obtain a mixture B for standby application; 3, mixing the mixture A with the mixture B uniformly, shearing the mixed solution to obtain the pigment violet 19 dispersion. The pigment violet 19 dispersion prepared by adopting the preparation method provided by the invention has the characteristics of good dispersing performance and stable color value.

Description

technical field [0001] The invention belongs to the field of pigments, and relates to a pigment violet 19 dispersion and a preparation method thereof. Background technique [0002] The application proportion of organic pigments in the coatings industry is constantly increasing. At present, it accounts for about 26% of the use of coloring pigments in coatings. The demand for organic pigments is growing rapidly, and more and higher requirements are put forward for their varieties and properties, which provides a good opportunity for the development of organic pigment industry. In order to meet the construction and functional performance, high-performance coatings should have good dispersion and storage stability, and their coating films should have excellent UV resistance, weather resistance, solvent resistance, stain resistance, scratch resistance, and Excellent water resistance, acid resistance, alkali resistance, etc. If it is a baking coating, it must also have excellent...
