Color masterbatch is a plastic colorant that is well dispersed by a high proportion of pigments or additives and thermoplastic resins. It has the advantages of excellent coloring effect, easy automatic measurement and transportation, energy saving, no dust, no pollution, etc. It is widely used in the coloring of materials such as paints and coatings. In the production process of color masterbatch, the quality of pigment directly affects the quality of color masterbatch, and the quality of color masterbatch directly affects the quality of plastic products. However, there is no national standard for pigments used in masterbatches, and the standard for pigments used in coatings has always been used for 30 years. There is no own industry standard, which has led to the low quality of the products of some masterbatch enterprises. Therefore, the entire industry is eagerly hoping that the country can issue standards for pigments used in masterbatches as soon as possible, so as to further standardize the standards of masterbatch products and ensure that The quality of color masterbatch products in the whole industry.
Titanium dioxide also plays a special role in the production of color masterbatches. According to incomplete statistics, the titanium dioxide used in the production of color masterbatches is 20,000 to 30,000 tons per year. Imported rutile is used, domestic rutile is used for mid-range products, and domestic anatase titanium dioxide is used for low-end products. Domestic color masterbatch, due to fierce competition, the use of anatase titanium dioxide color masterbatch is still increasing, resulting in low quality of domestic color masterbatch products, which does not meet the current social needs. This situation will be alleviated only if the country steps to standardize the color masterbatch industry and improve the competitiveness of color masterbatch enterprises.
In China, there are as many as 400 color masterbatch manufacturers in China, mainly located in Guangdong, Zhejiang, Tianjin and other provinces and cities. Among them, there are more than 50 enterprises with an annual production capacity of more than 1,000 tons, all over the country. However, the total demand for color masterbatch in the country is less than 120,000 t/a, and the production capacity is seriously excessive, which leads to the general shortage of domestic color masterbatch industry, and the market competition is very fierce. The reasons for the serious excess production capacity include factors such as the rapid growth rate of new production facilities and insufficient product orders. Among them, domestic color masterbatch products have a single structure, incomplete varieties, and general-purpose products account for a large proportion, while high-concentration and ultra-high-concentration, The low proportion of multifunctional masterbatches and masterbatches for fine fibers is also an important factor. On the other hand, countries with a high level of masterbatch technology have complete varieties of raw materials such as pigments and dispersants, and have formed a serialized and specialized product structure. Only when we further control the number of color masterbatch enterprises and optimize their products, can our color masterbatch manufacturers have a place in the market competition. Otherwise, under the impact of foreign products, my country's color masterbatch enterprises There will be no place to stand.
The foreign color masterbatch market is mainly concentrated in Western Europe, North America and Japan. Most of the enterprises producing color masterbatch are multinational companies or Fortune 500 companies, such as American Hanna, PoIyone, Ruitu Ciba-Geigy and other companies. Among them, the annual sales volume of Hanna Company reaches 140,000 tons, and the annual sales performance of Colloids Company in the United Kingdom is 55 million US dollars. Colloids recently announced that it will build a masterbatch production plant with a total area of 3,700 square meters and an initial production capacity of 3,500 tons in Jiangsu, China. Meanwhile, Clariant, the world's leading manufacturer of specialty chemicals, has launched a new black masterbatch. Crafted with Clariant Cool Black technology, the new product has excellent cooling capabilities and will be widely used in carpet textile production.
Only when we continuously improve the technological competitiveness of color masterbatch enterprises and the quality of employees, optimize the structure of the enterprise, and improve the comprehensive competitiveness of the enterprise, China's color masterbatch enterprises can occupy a place in the future market and adapt to the needs of society. .
