Masterbatch is a new type of polymer material colorant, which has superior coloring performance, energy saving, no dust, no pollution, and is widely used for coloring plastics, building profiles and agricultural pipes.

Masterbatch is composed of an excess of chemical additives, carrier resin and dispersant. The masterbatch is an aggregate obtained by uniformly supporting an excessive amount of a pigment (dye) in a resin. Masterbatch consists mainly of pigments, dispersants and carrier resins.

Color masterbatch is divided into organic pigments and inorganic pigments.

Commonly used organic pigments are: phthalocyanine red, phthalocyanine blue, phthalocyanine green, fast red, macromolecule red, macromolecular yellow, permanent yellow, permanent purple, azo red and so on.

Commonly used inorganic pigments are: cadmium red, cadmium yellow, titanium dioxide, carbon black, red iron oxide, yellow iron oxide and so on.

Masterbatch technology is very strict process requirements, the commonly used masterbatch technology is a wet process. The masterbatch is ground, phase-transformed, washed, dried and granulated in the aqueous phase. Only the quality of the product can be guaranteed. In addition, the pigments should also be subjected to a series of masterbatch techniques, such as measuring the fineness of the sand slurry, measuring the diffusion properties of the sand slurry, determining the solid content of the sand slurry, and measuring the fineness of the colorant. project.

Six advantages of using masterbatch:

1, is conducive to maintaining the chemical stability of the pigment and the stability of the color;

2. Make pigments have better dispersion in plastics;

3, protect the health of operators;

4, the process is simple, easy to change colors;

5, the environment is clean, do not stain the dishes;

6, save time and raw materials.

As the pigments directly contact the air during storage and use, moisture absorption, oxidation, clumping, etc. may occur. Direct use will cause color spots on the surface of the plastic products, and the hue will be dark, the color will be easily faded, and the color will be mixed. Dust is flying and affects the health of operators. The masterbatch has undergone mechanical processing during the production process. The pigment has been refined, and the pigment and resin carrier and dispersant have been fully mixed to separate the pigment from air and moisture, thereby enhancing the weather resistance of the pigment and improving the pigment. The pigment's dispersibility and coloring power, bright hue. Since the color masterbatch and the resin particles are similar in shape, they are more convenient and accurate in metering, and do not adhere to the container when mixed, thereby saving the time for cleaning the container and the machine and the raw materials used for the cleaning.
