The full name of Color Master Batch is color master batch, also known as color, is a new type of polymer material special coloring agent, also known as Pigment Preparation. Masterbatches are mainly used in plastics. Color master is composed of Pigment or dye, carrier and additive three basic elements, is a super constant pigment uniformly attached to the resin and made of aggregates, can be called pigment Concentration (Pigment Concentration), so its coloring power is higher than the pigment itself. During processing, a small amount of color masterbatch is mixed with uncolored resin to achieve the coloring resin or product with the design pigment concentration. [1]
Chinese name color master
The foreign name Color Master Batch
Don't call it color
Full color masterbatch
Good dispersion, easy to use and so on
To prepare resin and bulk pigments
1. Pigments or dye pigments are divided into organic pigments and inorganic pigments commonly used organic pigments are: phthalocyanine red, phthalocyanine blue, phthalocyanine green, fast bright red, macromolecular red, macromolecular yellow, permanent yellow, permanent purple, azo red and other commonly used inorganic pigments are: cadmium red, cadmium yellow, titanium dioxide, carbon black, iron oxide red, iron oxide yellow, etc. 2. The carrier is the matrix of the masterbatch. The special masterbatch generally chooses the same resin as the product resin as the carrier, and the compatibility of the two is the best, but at the same time, the fluidity of the carrier should also be considered. 3. The dispersant promotes the pigment to disperse evenly and no longer condense. The melting point of the dispersant should be lower than that of the resin, and it has good compatibility with the resin and good affinity with the pigment. The most commonly used dispersants are: polyethylene low molecular wax, stearate. 4. Additives such as flame retardant, brightening, antibacterial, antistatic, antioxidant and other varieties, unless the customer requests, under normal circumstances, the color master does not contain the above additives.
