The full name of the masterbatch masterbatch also known as the kind of color masterbatch is a new type of polymer materials colorants, also known as the pigment preparations. Is an extraordinary amount of pigment or dye is uniformly contained attached to the obtained resin and aggregate. It is composed by the pigments or dyes, the carrier and a dispersing agent are three basic elements. A pigment or a dye: The pigment divided into organic pigments and inorganic pigments Common organic pigments include: phthalocyanine red, phthalocyanine blue, phthalocyanine green, Fast Scarlet, macromolecular, macromolecular yellow, Permanent Yellow, Permanent Violet, azo red. Commonly used inorganic pigments are: cadmium red, cadmium yellow, titanium dioxide, carbon black, red iron oxide, yellow iron oxide, etc. 2 carrier Is an important component part of the masterbatch, and its role is to enhance the affinity between the pigment and the resin to be colored and to improve the dispersion and mixing of the coloring component and a resin. 3 dispersant Prompted the pigment is uniformly dispersed and no longer condensation the melting point of the dispersing agent should be lower than the resin, and have good compatibility with the resin, and the pigment has a good affinity. The most commonly used dispersant is a: Polyethylene low molecular waxes, stearates, white oil. |
