Masterbatch and masterbatch benefits and precautions for use
All over the world are implementing “plastic instead of steel”, which shows the development space and prospects of the plastics industry. Manufacturers in the plastics industry will deal with various types and colors of plastic particles, and provide a variety of plastic products for social production. Plastic products come in a variety of colors, so it is inevitable that plastic color matching services will be needed. Next, we invite experts in plastic color matching to introduce you to the knowledge of common masterbatch particle color matching. Advanced Polymer Technologies
1. What is masterbatch? Why use masterbatches?
Masterbatch is translated from the English Color Master Batch, and the full name is called Masterbatch, also known as color seed. Why Chinese is translated as color masterbatch, and is recognized by the majority of people, it is mainly understood from the literal meaning, color masterbatch, color mother, so more vivid! It’s like “failure is the mother of success”. This is the origin of the Chinese translation as color masterbatch.
Masterbatch, or masterbatch, is a new type of special colorant for polymer materials, also known as pigment preparation. Masterbatch is mainly used in plastics and is currently one of the most commonly used methods for plastic color matching. Masterbatch is composed of three basic elements: pigment or dyes, carriers and additives, and is an aggregate prepared by uniformly adhering an extraordinary amount of pigment in the resin, which can be called pigment concentration (Pigment Concentration), so its tinting strength is higher than that of the pigment itself. When processing, a small amount of color masterbatch and uncolored resin are blended to achieve the coloring resin or product with the design pigment concentration.
The benefits of using masterbatch color matching are as follows:
1. It is conducive to maintaining the chemical stability and color stability of pigments;
2. Make the pigment have better dispersion and expansion in plastics;
3. Protect the health of the operator and avoid injuries to the respiratory system;
4. The process is simple and the color change is easy;
5. The working environment is clean and does not stain the utensils;
6. Save time and raw materials.
Second, the advantages and disadvantages of pigment color matching and masterbatch color matching are used in plastic color matching
In the past, many plastic colors were matched with pigments or toners, and because pigments and toners were in direct contact with air during storage and use, moisture absorption, oxidation, agglomeration and other phenomena would occur, and direct use would cause color spots on the surface of plastic products, or make the hue dark and the color would be easy to fade. In addition, when pigments and toners are mixed, it is easy to cause dust and affect the health of operators. Customized Innovative Material Solutions
And if you use masterbatch extraction color matching, there are many benefits. The masterbatch has been processed in the production process, and the pigment has been refined, which is to fully mix the pigment with the resin carrier and dispersant, so that the pigment is isolated from air and moisture, thereby enhancing the weather resistance of the pigment, improving the dispersion and tinting strength of the pigment, and the hue is bright. Since the shape of the masterbatch and the resin particle are similar, it is more convenient and accurate in metering, and the page does not adhere to the container during mixing, so it saves time to clean the container and the machine, as well as the raw materials used in the cleaning machine.
The advantages of masterbatch are environmental protection, tasteless, non-toxic, smoke-free, and the appearance of the product is lubricated, shiny, and the resistance is also very good, and there will definitely be no undesirable phenomena such as color spots and color lines. The use of masterbatches not only reduces costs, saves additives, but also reduces pollution in the factory premises.
3. Matters needing attention when using masterbatch color matching for plastic color matching
When the plastic color matching, if the masterbatch carrier used is the same as the plastic variety of the product, it has good matching, and the pigment particles can be well dispersed and expanded in the product plastic after heating and melting. And if the varieties are not the same, or even contradictory, there will be many unpredictable situations. Therefore, the pigments used in masterbatches must pay attention to the matching relationship between pigments and plastic raw materials and additives. Innovative Polymer Solutions Japan
(1) The pigment of the masterbatch can not react with the resin and various additives, and has strong solvent resistance, small mobility and good heat resistance. That is, masterbatches cannot participate in various chemical reactions. For example, carbon black can control the curing reaction of polyester plastics, so carbon black materials cannot be added to polyester. Due to the high molding and processing temperature of plastic products, the pigment should not decompose and change color under the condition of molding heating temperature. Generally, inorganic pigments have good heat resistance, and organic pigments and dyes have poor heat resistance, which should be paid enough attention to when selecting pigment varieties.
(2) The dispersion and tinting strength of the pigment should be good. When the pigment is unevenly dispersed, it will affect the appearance and performance of the product; When the pigment tinting strength is poor, the amount of pigment will increase, and the material cost will increase. The dispersion and tinting strength of the same pigment are not the same in different resins, so this should be paid attention to when choosing a pigment. The particle size of the pigment is also related to the dispersibility, the smaller the particle size of the pigment, the better the dispersion and the stronger the tinting strength.
(3) Other properties of pigments should be understood. For example, for plastic products used in food, children’s toys, etc., the pigments are required to be non-toxic; For plastic products used in electrical appliances and other aspects, pigments with good electrical insulation properties should be selected; For outdoor plastic products, pigments with good weather resistance and aging resistance should be selected.
The selection and use of masterbatch directly affects the quality and appearance of the product, so we must choose the masterbatch developed and produced by regular manufacturers, whose quality is more trustworthy and the service is more comfortable. Moreover, the amount of masterbatch is generally not large, and it is not for a little cost, which affects the product quality and appearance, and also affects the company’s reputation and long-term interests. Korea Chemical Industry Co., Ltd. is an international company, and has established a standardized production base in Dongguan, Guangdong, to provide high-quality, cost-effective masterbatch granulation and color matching services to the market.
