Problems solved by technology

However, the traditional method of directly adding powdered pigments is still used in coloring, which has two disadvantages: firstly, dry powdered pigments are easy to drift and be inhaled by the human respiratory tract during mixing, polluting the environment and affecting health; secondly, most of the ordinary pigments are in 400 mesh , that is, the particle size is about 38 microns, and the amount of pigments with the same effect is about 10 times that of imported pigments with 1000-1200 mesh and particle size of 10-13 microns, and the price of imported pigments is 20-25 times that of ordinary pigments.

Embodiment Construction

[0007] According to the percentage by weight, 70-75% of polyurethane resin and 25-30% of dimethylbenzene are stirred and mixed to form a resin liquid component.

[0008] Resin liquid component 54%, titanium dioxide 35%, light calcium carbonate 10%, triethanolamine 1%, in the case of stirring the resin component, add titanium dioxide and then add light calcium carbonate until the solid powder is completely wet Finally, add triethanolamine, and then stir for about half an hour to grind it into a white pigment paste;

[0009] 59% of resin liquid components, 20% of carbon black, 20% of light calcium carbonate, and 1% of triethanolamine are processed into black pigment paste in the same way;

[0010] 54% of resin liquid components, 25% of pigment blue, 20% of light calcium carbonate, and 1% of triethanolamine are processed into blue color paste by the same method;

[0011] Add pigment red to make red color paste, add pigment yellow to make yellow color paste, the formula is the sa...

Abstract

The invention relates to a pigment color paste for PU (polyurethane) artificial leather, which adopts dimethylbenzene as a regulating solvent and polyurethane resin as a pigment vector to be prepared into resin liquid components, and triethanolamine as a dispersing agent, light calcium carbonate as stuffing and titanium white, carbon black, phthalocyanine blue, phthalocyanine blue red and everbrightfastyellow as color developing pigments. The invention can ensure that the stuffing and one of the pigments is blended with the resin liquid components, and the dispersing agent is added to be fully stirred and then grinded by a three-roller grinder, and the fineness is between 3 to 5 micrometers.

Description

Technical field: [0001] The invention relates to a kind of polyurethane, PU pigment color paste, in particular to the colored color paste used in the production of PU artificial leather. Background technique: [0002] PU artificial leather, that is, polyurethane artificial leather, has been widely used in all aspects of people's lives. However, the traditional method of directly adding powdered pigments is still used in coloring, which has two disadvantages: firstly, dry powdered pigments are easy to drift and be inhaled by the human respiratory tract during mixing, polluting the environment and affecting health; secondly, most of the ordinary pigments are in 400 mesh , that is, the particle size is about 38 microns, and the amount of pigment used for the same effect is about 10 times that of imported pigments with a particle size of 10-13 microns and 1000-1200 mesh, and the price of imported pigments is 20-25 times that of ordinary pigments. Expensive shades are watered do...
