Plastic liquid coloring agent and preparation technology thereof

The invention mainly discloses a plastic liquid coloring agent and a preparation technology thereof.The preparation technology is characterized in that an organic polymer of organic polyether is taken as a carrier, one or more kinds of organic or inorganic powder coloring agents are added, a dispersing agent, a defoaming agent and various functional auxiliaries also can be added, pigments are smashed to be in the minimum particle size through dispersing and grinding, therefore, the color powder points and spots on the surface of a plastic product can be effectively reduced, the surface smoothness of the plastic product is improved, the pigment dosage of the unit area of the plastic is decreased, and the influences on a plastic body are reduced.The plastic liquid coloring agent is used by cooperating with a color oil meter and a stirring connector and has the advantages of being easy to operate, free of pollution, bright in color, uniform in coloring, good in color stability, capable of saving time and labor and the like.
