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

[0006] According to the weight percentage, 70-75% of polyurethane resin and 25-30% of dimethylbenzene are stirred and mixed to form a resin liquid component.

[0007] Resin liquid composition 54%, titanium dioxide 35%, light calcium carbonate 10%, triethanolamine 1%, while stirring the resin composition, add titanium dioxide and then light calcium carbonate until the solid powder is completely wet Then add triethanolamine and stir for about half an hour to grind it into a white pigment paste;

[0008] 59% of resin solution, 20% of carbon black, 20% of light calcium carbonate, 1% of triethanolamine are processed into black pigment paste by the same method;

[0009] 54% of resin liquid composition, 25% of pigment blue, 20% of light calcium carbonate, and 1% of triethanolamine are processed into blue color paste by the same method;

[0010] Add pigment red for red color paste, add pigment yellow for yellow color paste, the formula is the same as blue.

[0011] When the upper three-roll mi...

Abstract

The invention discloses polyurethane pigment color paste. Dimethylbenzene serves as an adjusting solvent; polyurethane resin serves as a pigment carrier; a resin solution component is prepared in proportion; triethanolamine serves as a dispersing agent; light catcium carbonate serves as a filling material; and titanium dioxide, carbon black, phthalocyanine blue, phthalocyanine red and sun-proof yellow serve as developing pigments. In a preparation process, the filling material and one of the pigments are fused in the resin solution component, the dispersing agent is added, sufficient stirring is performed, grinding is performed by a three-roller grinder, and the fineness shall be 3-5 micrometers.

Description

Technical Field: [0001] The invention relates to a polyurethane pigment paste, in particular to a color paste used in the production of PU artificial leather. Background technique: [0002] Polyurethane artificial leather has been widely used in all aspects of people's lives. However, the traditional method of adding powdered pigments is still used in coloring. There are two disadvantages: first, dry powdered pigments are easy to drift and inhaled by the human respiratory tract during mixing, polluting the environment and affecting health; secondly, common pigments are mostly 400 mesh , That is, the particle size is about 38 microns, and the amount of pigment with the same effect is about 10 times that of imported pigments with a particle size of 10 to 13 microns from 1000 to 1200 mesh. The price of imported pigments is 20 to 25 times that of ordinary pigments. Due to the valet color matching service of imported pigments, the expensive shades are diluted. Summary of the inventi...
