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] By weight percentage, 50% cyclohexanone, 5% PVC resin powder, 30% polyurethane resin, 15% dibutyl phthalate, first dissolve the PVC resin powder in cyclohexanone by heating in a water bath, and then dissolve the polyurethane resin. Finally, add dibutyl phthalate and stir thoroughly to prepare the resin liquid component for later use.

[0008] Take 54% of the resin liquid component, 35% of titanium dioxide, 10% of light calcium carbonate, and 1% of triethanolamine. When stirring the resin component, add titanium dioxide and then add light calcium carbonate, etc. After wetting, add triethanolamine, stir for about half an hour, and grind it into a white color paste;

[0009] Get 59% of resin liquid components, 20% of carbon black, 20% of light calcium carbonate, and 1% of triethanolamine to process into black color paste in the same way;

[0010] Get 54% of resin liquid components, 25% of pigment blue, 20% of light calcium carbonate, and 1% of triethanolamine are processe...

Abstract

The invention relates to a PVC artificial leather pigment color paste. Cyclohexanone is adopted as a main solvent and PVC resin powder is adopted as structural resin, and polyurethane resin is utilized to improve a shear force to improve the grinding performance; dibutyl phthalate is used as a wetting agent to be prepared into the component of resin liquid in proportion; triethanolamine is used as a dispersing agent, light calcium carbonate is used as filling, and a red, yellow, blue, black and white organic raw material is used as developing pigment. When in preparation, one of the filling and the pigment is fused into the component of the resin liquid; the dispersing agent is added; grind is carried out by a three-roller grinder after sufficient stirring, and the fineness is between 3-5 microns.

Description

Technical field: [0001] The invention relates to a polyvinyl chloride (PVC) pigment color paste, in particular to a colored color paste used in the production of PVC artificial leather. Background technique: [0002] PVC artificial leather, that is, polyvinyl chloride 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 pigments with the same effect is about 10 times that of imported pigments with a particle size of 1000 to 1200 microns and a particle size of 10 to 13 microns, and the price of imported pigments is 20 to 25 times that of ordinary pigments...
