Plastic liquid coloring agent and preparation technology thereof

Abstract

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.

Description

[0001] Field [0002] The invention belongs to the field of chemical industry, and more specifically relates to a plastic liquid colorant for modifying toner, and also relates to a preparation process of the colorant. Background technique [0003] The plastics industry has grown from scratch, from small to large, from weak to strong, and has developed for more than 130 years, and has made brilliant achievements. Looking back on the development history of the plasticization industry, as a new type of material, the application of plastic products has gradually penetrated into every corner of society. From industrial production to food, clothing, housing and transportation, "replacing steel with plastic" and "replacing wood with plastic" can be said Plastic products are everywhere. According to relevant data, the total output of plastic materials in the world reached 288 million tons in 2012, an increase of 3% over 280 million tons in 2011. In 2011, the world's total plastic pr...

Problems solved by technology

Although the color masterbatch solves the problems of some powder colorants, compared with the powder colorant, the color masterbatch is relatively low in versatility. A plastic raw material needs to correspond to a carrier color masterbatch, which can only Spot color is special, so its production process is more complicated: first, it needs to be proofed with toner according to the required color. Color contrast is required, if there is a color difference, it needs to be remade, which is not only time-consuming, laborious, waste of raw materials, but also increases production costs

Due to its high production cost, low versatility, and there are still problems such as uneven coloring effect, easy to produce color difference and inability to realize fully automatic production, which still restricts the development of the plastics industry.

[0010] Both powder colorants and color masterbatches will have a 5% pre-loss during the production process; and if the production is interrupted for some reason during the production process, the unused raw materials and colorants will not be able to be used again (because they have been previously used) Plastic raw materials and colorants are mixed evenly according to the proportion required for production), which will cause secondary waste, which is also an important reason why these two colorants cannot be used in the plastics industry for a long time
