Embodiment 1

[0024] see figure 1 , the present invention provides a technical solution: a color masterbatch production process for improving the coloring uniformity of plastic color masterbatches, the color masterbatch production process for improving the coloring uniformity of plastic color masterbatches is as follows:

[0025] Step 1: Put the organic pigment into a pulverizer for crushing, then select an organic pigment with a particle size of less than 1.2um, add the screened organic pigment and soap solution into the mixer, start the mixer for stirring, and after 20 minutes, the soap After soaking the organic pigment particles with liquid, a layer of saponified liquid will be formed on the surface of the particles. Raise the temperature of the stirrer to 50°C, then add magnesium chloride solution to the stirrer, and stir again for 1.5-2 hours. Magnesium ions can chemically react with the saponification liquid on the surface of the particles to form a protective layer of magnesium stear...

[0037] see figure 1, the present invention provides a technical solution: a color masterbatch production process for improving the coloring uniformity of plastic color masterbatches, the color masterbatch production process for improving the coloring uniformity of plastic color masterbatches is as follows:

[0038] Step 1: Put the organic pigment into a pulverizer for crushing, then select an organic pigment with a particle size of less than 1.2um, add the screened organic pigment and soap solution into the mixer, start the mixer for stirring, and after 20 minutes, put the The temperature of the stirrer is raised to 50°C, and then magnesium chloride solution is added to the stirrer, and after stirring again for 1.5-2 hours, the mixed liquid in the stirrer is filtered to retain the particles, and the retained particles are put into the 45- Low-temperature drying at a temperature of 55°C can obtain saponified pigment particles;

[0039] Step 2: Put the saponified pigment partic...

Abstract

The invention belongs to the technical field of plastic coloring, and particularly relates to a color master batch production process for improving the coloring uniformity of plastic color master batch. The color master batch production process for improving the coloring uniformity of the plastic color master batch comprises the steps of preparing saponified pigment particles, preparing modified pigment particles, mixing and polymerizing raw materials, cooling, drying, dicing and packaging. According to the invention, a magnesium stearate protective layer is generated on organic pigment particles by using a metallic soap method, the organic pigment particles can be prevented from being condensed during grinding under the protection of the magnesium stearate protective layer, then the organic pigment particles with the magnesium stearate protective layer are ground, then the surfaces of the organic pigment particles are charged through a polyacrylamide solution, the organic pigment particles are added into the molten polyethylene at the moment, and the organic pigment particles are mutually dispersed under the action of charge repulsive force, so that mutual gathering of the organic pigment particles is avoided, and the organic pigment particles are conveniently and uniformly mixed into the polyethylene.

Description

technical field [0001] The invention relates to the technical field of plastic coloring, in particular to a color masterbatch production process for improving the coloring uniformity of plastic color masterbatches. Background technique [0002] The full name of color masterbatch is color masterbatch, also called color seed, which is a new type of special colorant for polymer materials, also known as pigment preparation. Masterbatches are mainly used for plastic dyeing. Masterbatch is composed of three basic elements: pigment or dye, carrier and additive. It is an aggregate made by uniformly loading super-normal pigments in resin. It can be called pigment concentrate, so its coloring power is high. For the pigment itself, a small amount of masterbatch and uncolored resin are mixed during processing to achieve the colored resin or product with the designed pigment concentration. [0003] When plastics are colored, color masterbatches are often used for coloring. Color master...
