Chemical Composition Of Color Masterbatch

1. Pigment or dye

Pigments are divided into organic pigments and inorganic pigments

Commonly used organic pigments include phthalocyanine red, phthalocyanine blue, phthalocyanine green, sun resistant scarlet, macromolecular red, macromolecular yellow, YONGGU yellow, YONGGU purple, azo red, etc

Common inorganic pigments include: cadmium red, cadmium yellow, titanium dioxide, carbon black, iron oxide red, iron oxide yellow, etc

2. Carrier

It is the matrix of color masterbatch. The special color masterbatch generally selects the same resin as the product resin as the carrier. The compatibility between the two is the best, but the carrier should also be considered at the same time

Liquidity of the body.

3. Dispersant

Promote the pigment to disperse evenly and no longer agglomerate. The melting point of the dispersant 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 wax and stearate.

4. Additives

Such as flame retardant, brightening, antibacterial, antistatic, antioxidant and other varieties, unless required by customers, the color masterbatch generally does not contain the above additives.

Advantages And Application Of Color Masterbatch

Firstly, it makes the pigment have better dispersion in the product.

The pigment must be refined during the production of color masterbatch to improve the dispersion and coloring power of the pigment. The carrier of the special masterbatch is the same as the plastic species of the products, which has good matching, and the pigment particles can be well dispersed in the plastic of the products after heating and melting.

Secondly, It is beneficial to keep the chemical stability of pigment.

If the pigment is used directly, the pigment will absorb water and oxidation due to the direct contact with air during the storage and use process.

Thirdly, Ensure the stability of color of products

The color masterbatch particles are similar to the resin particles, so it is more convenient and accurate to measure, and it will not stick to the container when mixing, and the mixing with resin is more even, so it can ensure the stability of the added amount, and thus the stability of the color of the products.

Precautions For Color Masterbatch

The use of color masterbatch is very simple, as long as it is mixed with plastic resin in a certain ratio, and then extruded and molded in accordance with the requirements of various plastic processing processes. It can be used. It should be noted that when changing the color, the hopper must be cleaned and the residual material in the barrel of the machine must be rinsed out with the original color plastic or by adding screw cleaner. It is better to use a new filter, preferably with 100 mesh or more; pay attention to the correct temperature to prevent color change. Due to Since there are many factors in the production process, we strongly recommend users to debug the machine by themselves for the best results. In the process of debugging, if you encounter We will try our best to assist customers to solve every problem we can.
