Color masterbatch is a new special colorant for polymer materials, also known as pigment preparation. Color masterbatch is mainly used in plastics. The color masterbatch is composed of three basic elements: pigment or dye, medium and additive. It is an aggregate made by evenly loading a relatively fast amount of pigment into the resin. It can be called pigment concentrate, and its coloring power is higher than the pigment itself. When processing, a small amount of masterbatch and uncolored resin can be mixed to achieve the design pigment concentration of colored resin or products.
advantage
1. In order to make pigments have better permeability in products, it is necessary to optimize pigments in the production process of color masterbatch to improve the permeability and coloring power of pigments. The carrier of the special color masterbatch is the same as the plastic of the product, and has a good match. After heating and melting, the pigment particles can be well dispersed in the plastic of the product.
2. If the pigment is used directly to maintain the chemical resistance of the pigment, because the pigment contacts with gas during storage and use, the pigment will appear moisture absorption, oxidation and other phenomena, and after the preparation of the color master batch, the quality of the pigment will remain unchanged for a long time because the resin medium will protect the pigment from air and water.
3. Ensure that the stable color masterbatch particles of the products are close to the resin particles, which is more convenient and accurate in measurement. When mixing, it will not adhere to the utensils, and the mixing with the resin is also more symmetrical. Therefore, it can ensure the stability of the addition amount, thus ensuring the stability of the product color.
4. The health pigments for maintenance operators are generally powdery, which are easy to fly when added and mixed, and will affect the health of operators after being absorbed by human body.
5. Keep the environment clean.
6. Easy to use.
The heat-resistant grade of color masterbatch is generally matched with the plastic used for products. It can be used safely at normal temperature. Only the following conditions can cause a certain degree of discoloration: first, the temperature is outside the normal range, and second, the shutdown time is too long.
