Embodiment Construction

[0007] By weight percentage, polypropylene 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 solid powder is completely wet, add triethanolamine, and then stir for about half an hour, then it can be ground into a white color paste by a three-roller mill;

[0008] 54% of polypropylene 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;

[0009] 49% of polypropylene 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;

[0010] 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.

[0011] When grinding on the upper three-roller ...

Abstract

The invention discloses a polypropylene pigment paste, which is prepared by using polypropylene white mineral oil as a pigment carrier, using triethanolamine as a dispersing agent and using red, yellow, blue, black and white organic pigments as color rendering pigments through the steps of fusing one of the pigments into the polypropylene white mineral oil, adding the dispersing agent, fully mixing the obtained mixture, and grinding the obtained mixture by a three roller, wherein the grinding fineness is between 3 and 5 microns.

Description

Technical field: [0001] The invention relates to a polypropylene pigment color paste, which is a pigment color paste used to replace powdery pigments in the production of polypropylene plastic products. Background technique: [0002] Polypropylene 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 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 down thanks to vale...
