Example Embodiment

[0022] Example 1

[0023] Add 300 grams of 20% aqueous formaldehyde solution to an appropriate amount of ammonia to adjust the pH of the solution to 8.5 to obtain a basic formaldehyde solution; immediately mix the formaldehyde solution with 1 kg of phthalocyanine blue 15:1 pigment, and then mix the mixture , Ball mill grinding for 1 hour, and add 122 grams of urea 10 minutes after the start of the ball mill grinding, and continue to grind to obtain a ground product; mix the above ground product and 2.9 kg of aqueous solution for 40 minutes, then filter and separate, rinse and dry to obtain Surface modified phthalocyanine blue 15:1 pigment.

Example Embodiment

[0024] Example 2

[0025] Add 400 grams of 10% aqueous formaldehyde solution to an appropriate amount of triethanolamine to adjust the pH 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 and ball mill the mixture. Grind for 1 hour, and add 95 grams of urea 10 minutes after the start of the ball mill grinding, and continue to grind to obtain a ground product; the above ground product and 7.3 kg of aqueous solution are mixed and stirred for 40 minutes, and then separated by filtration, rinsed with water and dried to obtain a modified surface Sexual phthalocyanine green pigment.

Example Embodiment

[0026] Example 3

[0027] Add 400 grams of 20% aqueous formaldehyde solution to an appropriate amount of triethanolamine to adjust the pH of the solution to 9.0 to obtain a basic formaldehyde solution; immediately mix the formaldehyde solution with 1 kg of phthalocyanine blue 15:3 pigment, and then the mixture Mix and grind with a ball mill for 1 hour, and add 175 grams of urea 10 minutes after the start of the mill, and continue to grind to obtain a milled product; mix the milled product with 5.5 kg of aqueous solution for 50 minutes, then separate by filtration, rinse and dry with water 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...
