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

[0007] Take 54% of the resin liquid component, 35% of titanium dioxide, 10% of light calcium carbonate, and 1% of triethanolamine. In the case of stirring the resin component, add titanium dioxide and then add light calcium carbonate, etc. After wetting, add triethanolamine, and stir for about half an hour to grind it into a white color paste;

[0008] 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;

[0009] Get 54% of resin liquid components, 25% of pigment blue, 20% of light calcium carbonate, and 1% of triethanolamine are processed into...

Abstract

The invention discloses polyvinyl chloride (PVC) pigment color paste. Cyclohexanone serves as a main solvent; PVC resin powder serves as structural resin; polyurethane resin is used for increasing a shear force and improving the grinding performance; dibutyl phthalate serves as a wetting agent; a resin solution component is prepared in proportion; triethanolamine serves as a dispersing agent; light catcium carbonate serves as a filling material; and red, yellow, blue, black and white organic raw materials 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 polyvinyl chloride pigment color paste, in particular to a colored color paste used in the production of PVC artificial leather. Background technique: [0002] PVC artificial leather has been widely used in every aspect of people's life. 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. Expensive shades are watered down thanks to valet co...
