Problems solved by technology

But, use the water-based color paste prepared by the modified phthalocyanine pigment of the above-mentioned prior art, when being used for viscose liquid coloring, in the spinning process, due to the poor adsorption and matching of the dispersing aid and the pigment surface, Moreover, the compatibility between the spinning stock solution and the pigment particles is poor, and the water-based color paste prepared from the existing phthalocyanine pigments is still difficult to avoid the phenomenon of uneven coloring and easy clogging of the spinneret during the spinning process.

Embodiment 1

[0023] Add 300 grams of 20% formaldehyde solution and add an appropriate amount of ammonia water to adjust the pH value of the solution to 8.5 to obtain an alkaline formaldehyde solution; immediately mix the formaldehyde solution with 1 kg of phthalocyanine blue 15:1 pigment, and then mix the mixture 1. The ball mill was ground for 1 hour, and 122 grams of urea was added 10 minutes after the ball mill started to grind, and the grinding was continued to obtain the ground product; the above-mentioned ground product and 2.9 kilograms of aqueous solution were mixed and stirred for 40 minutes, then separated by filtration, rinsed with clear water and dried to obtain Surface modified phthalocyanine blue 15:1 pigment.

Embodiment 2

[0025]Add 400 grams of 10% formaldehyde solution and add an appropriate amount of triethanolamine to adjust the pH value of the solution to 8.0 to obtain an alkaline formaldehyde solution; immediately mix the formaldehyde solution with 1 kg of phthalocyanine green pigment, and then mix the mixture with a ball mill Grind for 1 hour, and add 95 grams of urea 10 minutes after the start of ball mill grinding, and continue grinding to obtain a grinding product; mix and stir the above-mentioned grinding product and 7.3 kg of aqueous solution for 40 minutes, then filter and separate, rinse with water and dry to obtain a surface modification. Phthalocyanine green pigment.

Embodiment 3

[0027] Add 400 grams of 20% formaldehyde solution and add an appropriate amount of triethanolamine to adjust the pH value of the solution to 9.0 to obtain an alkaline formaldehyde solution; immediately mix the formaldehyde solution with 1 kg of phthalocyanine blue 15:3 pigment, and then pass the mixture through Mix and grind in a ball mill for 1 hour, and add 175 grams of urea 10 minutes after the start of the ball mill grinding, and continue grinding to obtain a grinding product; mix and stir the above grinding product and 5.5 kg of aqueous solution for 50 minutes, then separate by filtration, rinse with water and dry A surface-modified phthalocyanine blue 15:3 pigment was obtained.

Abstract

The invention relates to phthalocyanine pigment water-based color paste for coloring viscose stock. The color paste is prepared from a surface-modified phthalocyanine pigment, a dispersing agent, a wetting agent, an organic solvent, a mildew-proof bactericide and de-ionized water through such processes as dispersing, mixing, grinding, de-aerating and filtering. The color paste disclosed by the invention is used for coloring the viscose stock, and has such advantages as being uniform to color and capable of preventing a spinning jet from being blocked; and a coloring effect and a spinning property are excellent.

Description

technical field [0001] The invention relates to the technical field of fine chemicals, more specifically, the invention relates to a phthalocyanine pigment water-based color paste for viscose glue coloring and a preparation method thereof. Background technique [0002] Viscose fiber is an extremely important regenerated cellulose fiber. It uses natural cellulose such as wood or cotton linters as raw materials. It is first impregnated with caustic soda to make alkali cellulose, and then combined with carbon disulfide to form cellulose. Sodium sulfonate, then dissolve sodium cellulose sulfonate in dilute lye to form a viscose spinning stock solution, and then use the viscose solution as a spinning stock solution and spray it into a strongly acidic spinning bath through a spinneret Solidification, decomposition, regeneration to obtain viscose fiber. Compared with chemical fibers such as acrylic and polyester, viscose fiber has a wide range of raw materials, and the raw materia...
