What are some basic knowledge about color masterbatch?
First, what are some basic knowledge about color masterbatch? Color masterbatch is also a new coloring agent for polymer materials, also known as Pigment Preparation. It consists of three basic elements: pigment or dye, carrier and additive. It is an aggregate obtained by uniformly loading a super-constant pigment or dye into a resin. It can be called Pigment Concentration, so he The tinting strength is higher than the pigment itself. To put it simply, color masterbatch is an aggregate made by uniformly loading a super-constant pigment or dye into a resin.
Second, what are the basic components of the color masterbatch? The basic components of the color masterbatch are: Pigment or dye
Pigments are further divided into organic pigments and inorganic pigments. Commonly used organic pigments are: phthalocyanine red, phthalocyanine blue, phthalocyanine green, fast red, macromolecular red, macromolecular yellow, permanent solid yellow, permanent solid purple, azo red, etc.
Commonly used inorganic pigments are: cadmium red, cadmium yellow, titanium white powder, carbon black, iron oxide red, iron oxide yellow, etc.
2. Carrier It is the matrix of the masterbatch. The special color master generally selects the same resin as the carrier resin as the carrier, and the compatibility between the two is the best, but the fluidity of the carrier is also considered. 3. Dispersant The pigment is uniformly dispersed and no longer aggregates. The melting point of the dispersing agent should be lower than that of the resin, have good compatibility with the resin, and have good affinity with the pigment. The most commonly used dispersants are: polyethylene low molecular waxes, stearates. 4. Additives
Such as flame retardant, brightening, antibacterial, antistatic, anti-oxidation and other varieties, unless the customer asks, in general, the color masterbatch does not contain the above additives.
