Color masterbatch
11/16/2018
Masterbatch consists of a high proportion of pigments or additives and thermoplastic resins, a well-dispersed plastic colorant.
The
resin selected for its use has good wetting and dispersing properties
to the colorant and good compatibility with the pigmented material.
Namely: pigment + carrier + additive = masterbatch
A common coloring method for the use of colored masterbatch.
After being mixed with a colorant and granulated into a colored plastic, it is used in a molding process.
Dry powder coloring, the powdered colorant is uniformly mixed with the natural color resin and directly used in the manufacturing plastic products.
Masterbatch coloring is the most commonly used plastic coloring method today.
It is used in the manufacture of plastic products after being simply mixed with the original color masterbatch resin.
The significant advantages of color masterbatch coloring are easy to use and have no pollution to the molding environment. Uniform coloring, stability, and improve the quality of plastic parts.
Easy to measure, it can be applied to a highly automated molding production system.
A
colored anti-aging agent, an antistatic agent, and the like can be
combined in one side to form a multifunctional masterbatch, which is
convenient to use.
The masterbatch technology generally used in the masterbatch technology process is a wet process. The masterbatch is ground, phase-inverted, washed with water,
Dry and granulated, only the quality of the product can be guaranteed. In addition, the pigment is processed while being ground.
A
series of masterbatch techniques should also be tested, such as
determining the fineness of the sanding slurry, determining the
diffusion properties of the sanding slurry,
Determine the solid content of the sanding slurry and determine the fineness of the colorant.
The masterbatch is generally composed of three parts.
Colorant
carrier dispersant, after being kneaded by high-speed mixer, crushed,
extruded and granulated, and masterbatch processed in plastic.
In the process, it has the advantages of high concentration, good dispersibility, and cleanness.
