What is a masterbatch? Why use a masterbatch? Masterbatch is an aggregate made by uniformly loading an ultra-constant amount of pigment into a resin.
The use of masterbatch has the following advantages:
1. Allows pigments to have better dispersion in the product. The pigment must be refined during the color masterbatch to increase the dispersibility and color strength of the pigment. The carrier of the special color masterbatch is the same as the plastic type of the product and has a good match. The pigment particles can be well dispersed in the plastic of the product after heating and melting.
2. It helps to maintain the chemical stability of pigments. If pigments are used directly, the pigments will absorb water, oxidize, etc. due to direct contact with the air during storage and use. After the masterbatch is prepared, the resin carrier separates the pigment from air and moisture. , can make the quality of pigments long-term unchanged.
3. The stable color masterbatch that guarantees the color of the product is similar to the resin particles, and it is more convenient and accurate in metering. When it is mixed, it will not adhere to the container. The mixture with the resin is also more uniform, so the stability of the additive amount can be ensured, thereby ensuring the color of the product. Stability.
4. The health pigments used to protect operators are generally powdery, and they are easy to fly when they are added and mixed. Inhalation by humans will affect the health of operators.
5. Keep the environment clean 6 . What are the basic ingredients for using the convenient masterbatch?
The basic composition of masterbatch is:
1. Pigments or dyes pigments are divided into organic pigments and inorganic pigments. Commonly used organic pigments are: phthalocyanine red, phthalocyanine blue, phthalocyanine green, lightfast red, macromolecule red, macromolecular yellow, permanent yellow, permanent purple, Azo red and so on. Commonly used inorganic pigments are: cadmium red, cadmium yellow, titanium dioxide, carbon black, red iron oxide, yellow iron oxide, etc. 2. The carrier is the matrix of the masterbatch. The special masterbatch generally chooses the same resin as the product resin as the carrier, and the compatibility between the two is best, but at the same time, the fluidity of the carrier should also be considered.
3. The dispersant promotes uniform dispersion of the pigment and no longer coagulates. The dispersant should have a lower melting point than the resin, good compatibility with the resin, and a good affinity for the pigment. The most commonly used dispersants are: polyethylene low molecular waxes, stearates.
4. Additives such as flame retardant, brightening, antibacterial, antistatic, anti-oxidation and other varieties, unless the customer requests, normally does not contain the above additives in the masterbatch. What color classification and grade?
Color master classification methods are commonly used as follows:
According to carrier classification: such as PE masterbatch, PP masterbatch, ABS masterbatch, PVC masterbatch, EVA masterbatch, etc. According to the use of categories: such as injection masterbatch, blow masterbatch, spinning masterbatch and so on. All varieties can be divided into different levels, such as:
1. Advanced color masterbatch for cosmetic packaging, toys, electrical enclosures and other advanced products.
2. Ordinary injection masterbatch is used for general daily-use plastic products, industrial containers, etc.
3. High-grade blown film masterbatch is used for blow molding of ultrathin products.
4. Ordinary blown film masterbatch is used for blow molding of general bags and woven bags.
5. Spinning masterbatch is used for textile fiber spinning, pigment masterbatch, high concentration, strong coloring, heat and light resistance.
6. Low-grade color masterbatch is used to manufacture low-grade products with low requirements on color quality, such as trash cans and low-grade containers.
How to distinguish between universal masterbatch and special masterbatch?
Special color masterbatch: It is a masterbatch manufactured by using the same plastic as a carrier according to the user's designated plastic type for the product. Such as PP color masterbatch, ABS masterbatch were selected PP, ABS as a carrier.
General Color Masterbatch: A resin (usually a low melting point PE) is also used as a carrier, but it may be suitable for the coloration of other resins than its carrier resin. General color masterbatch is relatively simple and convenient, but the disadvantages are more, it is recommended that you use a special masterbatch. Why do not many companies produce universal masterbatch? Most of the world's regular masterbatch companies generally do not produce universal masterbatches.
Universal masterbatch has many shortcomings. In fact, the general color masterbatch's 'universal' range is very narrow, with poor technical indicators and economic benefits.
1. Predictive color masterbatch of coloring effect is used for coloring, universal masterbatch pigments will show different colors in different plastics, so the predictability of coloring effect is poor.
2. Affecting the other properties of plastic products, especially affect the strength, the product is easily deformed, distorted, and more obvious to engineering plastics.
3. The higher cost universal masterbatch often uses a higher heat-resistant grade of pigment in order to be 'common', causing waste.
In addition to coloring, color masterbatch can also have flame retardant, brightening, anti-static, anti-oxidation, anti-ultraviolet and other functions?
Masterbatch can have some of these functions at the same time, if the factory makes this request. Sometimes, although the customer does not ask for it, the parent company will also advise the user to add some auxiliaries depending on the needs of the product, such as adding certain additives such as brighteners to the masterbatch. Of course, this will increase the cost of the product.
How is the heat resistance of masterbatch? The heat-resistance grade of the special masterbatch is generally compatible with the plastic used for the product, and it can be used safely at normal temperature. Only in the following circumstances will cause varying degrees of discoloration, one is the temperature exceeds the normal range, one is too long downtime.
What is the difference between granulation and masterbatch?
Masterbatch has the following advantages over granulation:
1. Coloring and product processing are completed at one time, avoiding the heating process of granulation and coloration on plastics, which is beneficial to the protection of the quality of plastic products.
2. Makes the production process of plastic products the most simplified.
3. Can you save a lot of energy Coloring products do not fade? There is no absolute non-fade products, the use of color mastering products are still likely to fade, but only for different grades of different product levels, some of the more obvious, and some are difficult to detect.
