Color Master Batch

Refers to a high proportion of pigments or additives and thermoplastic resins,

Well-dispersed plastic colorants.

The resin of its choice for colorants

Has good wetting and dispersing effect,

And with the coloring material has good compatibility.


Masterbatch the basic ingredients



Paint or dye

Pigments are 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 yellow, permanent purple, azo red, etc .;

Common inorganic pigments are: cadmium red, cadmium yellow, titanium dioxide, carbon black, red iron oxide, yellow iron oxide and so on.




2. Vector

The carrier is the masterbatch matrix. Special color masterbatch resin generally selected as the same resin as the carrier, the best compatibility between the two, but also to consider the carrier fluidity.


Dispersant

Promote uniform dispersion of pigment and no longer aggregate, the melting point of the dispersant should be lower than the resin, and the resin has good compatibility, and the pigment has better affinity. The most commonly used dispersants are: polyethylene waxes, stearates.


4. Additives

Such as flame retardant, brightening, antibacterial, anti-static, anti-oxidation varieties.


Masterbatch advantages


1. Make pigments have better dispersibility in products

Color Masterbatch is an aggregate of ultra-high levels of pigment uniformly loaded in the resin. Color Masterbatch in the production process to refine the paint to improve pigment dispersion and tinting strength. Special masterbatch carriers and products of the same plastic species, has a good match, heated and melted pigment particles can be well dispersed in the plastic products.


2. To help maintain the chemical stability of the pigment

Direct use of the pigment, the pigment in the process of storage and use of direct contact with air, the pigment will absorb water, oxidation and other phenomena, and made masterbatch, the resin carrier will pigment and air, water, can make the pigment quality long-term change.




3. To ensure the stability of color products

Masterbatch particles and resin particles close to the more convenient and accurate measurement, the mixing will not adhere to the container, and the resin is also more evenly mixed, so you can ensure the stability of the amount added to ensure product color stability.


4 to protect the health of operators

Pigments are generally powdered, easy to add when added and mixed, will be affected by human inhalation of the operator's health.


5. To keep the environment clean, non-staining containers


6 process is simple, color change is easy, save time and raw materials

As the pigment in the process of storage and use of direct contact with the air, so there will be absorption of moisture, oxidation, clumps and other phenomena, the direct use of plastic products appear in the surface color point, dark hue, color fade easily, and caused when mixed Dusty, affecting the health of operators.


The masterbatch in the production process through mechanical processing, the pigment was refined, the pigment and resin carriers, dispersants, mixing, the pigment and air, water, thereby enhancing the weathering of pigments and improve the Pigment dispersion and tinting strength, hue bright. The color masterbatch is similar in shape to the resin particles, making it more convenient and accurate to measure, and will not stick to the container when mixed, saving time and equipment used to clean the container and machine.



Precautions for using masterbatch


1, how to use the color master?

Masterbatch is very simple to use, just by the required ratio and resin particles mixed, hand-mixing can be.

In the operation of the equipment should pay attention to the following questions:

a. Injection molding machine or extruder mixing chamber generally has multiple temperature zones, of which the temperature near the discharge port should be slightly higher, which is to make the masterbatch into the mixing chamber quickly melted, and the plastic resin as soon as possible Mix well, which is good for the masterbatch pigment to be well dispersed in the product.

b. The injection molding machine applied back pressure, which can improve the screw mixing effect, the dispersion of pigment, the application of back pressure side effects is to make the injection speed has slowed down.

c. Extruder die temperature appropriate increase, can increase the brightness of products.




2, how to determine the proportion of masterbatch?

Color Masterbatch to determine the basis for the ratio, is to obtain a satisfactory coloring effect. As long as the product surface uniform color, no stripes and spots, it can be recognized.


3, how to calculate the use of masterbatch cost?

When calculating the cost of masterbatch pigmentation should be deducted from the weight of their own.


4, the use of color master will increase the cost of the product?

In most cases this is the case. In some cases, however, the use of masterbatch coloration is more economical than the use of colorants because the colorist can achieve the coloration of higher-priced pigments by combining several lower-priced pigments.


Of course, text information can only be used as a reference,

More knowledge needs to be found and summarized in practice.
