Black masterbatch is produced by evenly mixing dyes and corresponding polyethylene resin carriers, followed by high-energy extrusion through a precision co-rotating twin-screw extruder or rubber and plastic internal mixer, followed by cooling and pelletizing. Different production processes, different polyethylene carriers, and different pigments and additives will determine the quality and application of the color masterbatch.
The advantages of color masterbatch: environmentally friendly, non-toxic, odorless, smokeless. The products produced have a smooth and lustrous surface. The solid color is stable and will not have poor dispersion phenomena such as color spots, color patches, and color streaks like other pigments. This not only reduces costs but also minimizes the degradation of plastics due to repeated heating, reduces the intrinsic performance of plastics, saves the addition of other additives, reduces factory environmental pollution, and effectively meets national environmental protection standards.
The common types of color masterbatch classification are as follows:
one According to the carrier, they are classified as: PE color masterbatch, ABS color masterbatch, PVC color masterbatch, EVA color masterbatch, etc.
two By application, they can be classified as: such as injection molding extrusion masterbatch, blow molding blown film color masterbatch, spinning color masterbatch, etc.
What raw materials are used to make black masterbatch?
(1) Ink method: As the name suggests, it is a production method of ink color paste in the production of color masterbatches, that is, through three-roll grinding, a layer of low-molecular protective layer is coated on the surface of the pigment. The ground fine color paste is then mixed with the carrier resin, and then plasticized through a two-roll plasticizer (also known as a two-roll open mill), and finally granulated through a single-screw or twin-screw extruder.
(2) Rinsing method: It involves grinding pigments, water and dispersants through sand to make the pigment particles smaller than 1μm, and then transferring the pigments into the oil phase through the phase transfer method. After drying, masterbatches are obtained. When converting phases, organic solvents and corresponding solvent recovery devices are required.
(3) Kneading method: It involves blending the pigment with an oil-based carrier and taking advantage of the pigment's lipophilic property. Through kneading, the pigment is washed from the aqueous phase into the oil phase. At the same time, the surface of the pigment is coated by an oil-based carrier to ensure the dispersion and stability of the pigment and prevent it from coagulating.
What are the advantages of black masterbatch
In automotive interior materials, cable materials, chemical fiber coloring, and plastic packaging materials, the position of color masterbatches is extremely important. Especially in today's era of advocating for low-carbon environmental protection, masterbatch coloring technology has three major advantages: energy conservation and pollution-free coloring of the substrate.
