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] By weight percentage, white mineral oil 49%, titanium dioxide 35%, light calcium carbonate 15%, triethanolamine 1%, in the case of stirring white mineral oil, add titanium dioxide and then add light calcium carbonate, etc. After the ingredients are all wet, add triethanolamine, and then stir for about half an hour to grind on a three-roller grinder to form a finished white color paste;

[0007] 54% of white mineral oil, 20% of carbon black, 25% of light calcium carbonate, and 1% of triethanolamine are processed into finished black color paste by the same method;

[0008] 49% of white mineral oil, 25% of pigment blue, 25% of light calcium carbonate, and 1% of triethanolamine are processed into finished blue color paste by the same method;

[0009] Add pigment red to make red color paste, add pigment yellow to make yellow color paste, the formula is the same as that of blue.

[0010] When grinding on the upper three-roller grinder, the roller distance needs to be tighten...

Abstract

The invention discloses polystyrene pigment color paste. White mineral oil serves as a pigment carrier; triethanolamine serves as a dispersing agent; and red, yellow, blue, black and white organic pigments serve as developing pigments. In a preparation process, one of the pigments is fused in the white mineral oil, 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 polystyrene pigment color paste, which is a pigment color paste used to replace powdery pigments in the production of polystyrene plastic products. Background technique: [0002] Polystyrene plastic products have 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. Expensive shades are water...
