First, what is the color master?
Color masterbatch is also a new coloring agent for polymer materials, also known as Pigment Preparation. It consists of three basic elements: pigment or dye, carrier and additive. It is an aggregate obtained by uniformly loading a super-constant pigment or dye into a resin. It can be called Pigment Concentration, so he The tinting strength is higher than the pigment itself. To put it simply, color masterbatch is an aggregate made by uniformly loading a super-constant pigment or dye into a resin.
Second, what are the basic components of the color masterbatch?
The basic components of the color masterbatch are:
1. Pigments or dyes Pigments are further classified 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 Common inorganic pigments such as purple and azo red are: cadmium red, cadmium yellow, titanium white powder, carbon black, iron oxide red, iron oxide yellow, etc.
2. The carrier is the matrix of the masterbatch. The special color master generally selects the same resin as the carrier resin as the carrier, and the compatibility between the two is the best, but the fluidity of the carrier is also considered.
3. The dispersing agent promotes the uniform dispersion of the pigment and no longer aggregates. The melting point of the dispersing agent 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 waxes, stearates.
4. Additives such as flame retardant, brightening, antibacterial, antistatic, anti-oxidation, etc., unless the customer requests, in general, the color masterbatch does not contain the above additives.
3. What varieties and grades are the masterbatch?
The classification methods of color masterbatch are commonly used as follows: Classification by carrier: such as PE masterbatch, PP masterbatch, ABS masterbatch, PVC masterbatch, EVA masterbatch, etc., according to the purpose: such as injection masterbatch, blown color masterbatch , spinning masterbatch and other varieties can be divided into different levels, such as:
1. Advanced injection color masterbatch: used in cosmetic packaging boxes, toys, electrical enclosures and other advanced products.
2. Ordinary injection color masterbatch: used for general daily plastic products, industrial containers, etc. 3. Advanced blown film masterbatch: Used for blow molding coloring of ultra-thin products. 4. Ordinary blown film masterbatch: used for blow molding coloring of general packaging bags and woven bags.
5. Spinning color masterbatch: It is used for textile fiber spinning and coloring. The color masterbatch pigment particles are fine, the concentration is high, the tinting strength is strong, and the heat resistance and light resistance are good.
6. Low-grade color masterbatch: It is used to manufacture low-grade products that do not require high color quality, such as trash cans and low-grade containers.
7. Dedicated color masterbatch: It is a color masterbatch made of the same plastic as the carrier according to the plastic type specified by the user for the product. For example, PP color masterbatch and ABS color masterbatch respectively use PP and ABS as carriers. Universal color masterbatch: A resin (often a low melting point PE) is also used as a carrier, but it can be applied to the coloration of other resins than its carrier resin.
8. Universal color masterbatch Universal color masterbatch is relatively simple and convenient, but has many disadvantages. It is recommended that users choose a special color masterbatch. The heat resistance grade of the special color masterbatch is generally compatible with the plastic used for the product, and can be used with confidence at normal temperature. Only in the following cases will cause different degrees of discoloration, first, the temperature is beyond the normal range, first, the downtime is too long.
9. Color masterbatch has the following advantages compared with granulation coloring: 9.1. Coloring and product processing are completed once, avoiding the heating process of granulation coloring on plastic, which is beneficial to the quality of plastic products. 9.2. The production process of plastic products is simplified. 9.3. Can save a lot of energy. 4. Why use color masterbatch?
The use of color masterbatch has the following advantages:
1. Make the pigment have better dispersibility in the product: The color masterbatch is an aggregate obtained by uniformly loading a super-constant pigment into the resin. In the production process of the color masterbatch, the pigment must be refined to improve the dispersibility and tinting strength of the pigment. The carrier of the special color masterbatch has the same plasticity as the product, and has good matching property, and the pigment particles can be well dispersed in the product plastic after heating and melting.
2. Conducive to maintaining the chemical stability of the pigment: If the pigment is directly used, the pigment will absorb water and oxidize due to the direct contact of the pigment during storage and use, and after the color masterbatch, the resin carrier will be the pigment and the air. Water separation can keep the quality of the pigment unchanged for a long time.
3. To ensure the stability of the color of the product: The color masterbatch particles are similar to the resin particles, which are more convenient and accurate in metering, do not adhere to the container during mixing, and are evenly mixed with the resin, thereby ensuring the stability of the added amount, thereby To ensure the stability of the color of the product.
4. Protect the health of the operators: Pigments are generally powdery, easy to fly when added and mixed, and will affect the health of the operator when inhaled by the human body.
5. Keep the environment clean and not stained with utensils;
6. The process is simple, easy to change color, save time and raw materials: Since the pigment directly contacts the air during storage and use, moisture absorption, oxidation, agglomeration, etc. will occur, and the color point will appear on the surface of the plastic product when used directly. The hue is dark, the color is easy to fade, and it causes dust to fly when mixed, which affects the health of the operator. The masterbatch is mechanically processed in the production process to refine the pigment, and the pigment and the resin carrier and the dispersing agent are fully mixed to separate the pigment from the air and moisture, thereby enhancing the weather resistance of the pigment and improving the pigment. The dispersibility and tinting strength of the pigment, the hue is bright. Since the masterbatch is similar in shape to the resin particles, it is more convenient and accurate in metering, and does not adhere to the container during mixing, thereby saving time for cleaning the container and the machine and raw materials used for cleaning.
