In today's plastic processing industry, as an important colorant, color masterbatch is widely used in the production of various plastic products. Among them, black masterbatch has become a kind of color masterbatch with large demand in the market because of its special color properties and wide application fields. In this paper, the preparation process, properties, application field and market development trend of black masterbatch are discussed in depth.
I. Preparation process of black masterbatch
The preparation process of black masterbatch mainly includes the steps of raw material selection, mixing, melting, extrusion, cutting and packaging. Among them, the choice of raw materials is directly related to the quality and performance of black masterbatch. High-quality carbon black, resin and other additives are the key to the preparation of high-performance black masterbatches. The mixing process requires that various raw materials be evenly mixed to ensure that the carbon black is evenly dispersed in the resin to achieve a good coloring effect.
The melting and extrusion process is to fully fuse carbon black with resin through high temperature and high pressure to form a uniform black melt, and then extruded into strips by the extruder. The cutting process is to cut the extruded strip material into a certain length of particles, and finally package it to complete the preparation of black masterbatch.
Second, the performance characteristics of black masterbatch
Excellent coloring performance: The black masterbatch uses high-quality carbon black as a coloring agent, with bright color, strong coloring power, good hiding power and other characteristics, can meet the needs of various plastic products for black.
Good dispersion: By optimizing the preparation process and selecting the appropriate additives, the black masterbatch has good dispersion in the resin, which can effectively avoid the defects such as color spots and color spots on the surface of the product.
Stable physical properties: The black masterbatch can maintain stable physical properties during processing, such as melting point, fluidity, etc., to ensure the processing stability and quality consistency of the product.
Environmental safety: The black masterbatch strictly controls the use and emission of harmful substances during the production process, meets the requirements of environmental protection, and will not cause harm to the human body and the environment during use.
Third, the application field of black masterbatch
Black masterbatch is widely used in various fields of plastic products, such as packaging materials, building materials, auto parts, wire and cable, household appliances and so on. In packaging materials, black masterbatch is often used to make black plastic bags, packaging boxes, etc., which has good shading and aesthetics. In the field of building materials, black masterbatch can be used to produce black waterproof coils, pipes, etc., to improve the weather resistance and service life of products. In the auto parts, the application of black masterbatch is mainly reflected in the interior parts, exterior parts, etc., to improve the overall beauty and comfort of the car. In addition, in wire and cable and household appliances, black masterbatch also has a wide range of applications, providing good color effects and performance guarantees for products.
Fourth, market development trend
With the continuous progress of science and technology and the improvement of people's performance requirements for plastic products, the black masterbatch market shows the following development trends:
High performance: The market has increasingly high performance requirements for black masterbatches, such as higher coloring power, better dispersion, and more stable physical properties. Therefore, the development of high-performance black masterbatch will become an important development direction of the industry.
Green environmental protection: With the improvement of global environmental protection awareness, green environmental protection has become an inevitable trend in the development of black masterbatch. In the future, the production of black masterbatches will pay more attention to the selection of environmentally friendly materials and the application of cleaner production technology.
Customized services: The performance requirements of black masterbatches vary in different fields, so providing customized black masterbatches products and services will become an important means of competition for enterprises.
International development: With the deepening of global economic integration, the black masterbatch market will be more open and international. Domestic enterprises will face more opportunities for international competition and cooperation, and need to continuously improve their own strength to cope with market changes.
