Anti-oxidant industry is proactive

Antioxidant refers to the process of degrading or inhibiting the degradation of materials in the process of polymerization, storage, transportation, processing, and use by the action of oxygen or ozone in the atmosphere when only a small amount exists in the material system of the polymer material. Chemicals that age and prolong their useful life. Antioxidants are one of the most commonly used chemical additives in the manufacture of various types of polymer materials.

Antioxidants can be divided into main antioxidants and auxiliary antioxidants. Antioxidants that can eliminate free radicals include aromatic amines and hindered phenols and other compounds and their derivatives, which are called primary antioxidants; antioxidants that can decompose hydroperoxides include organic compounds containing phosphorus and sulphur, which are called assistants. Antioxidants. The main antioxidants are mainly divided into hindered phenol antioxidants and aromatic amine antioxidants. Aromatic amine antioxidants, also known as rubber antioxidants, are mainly used in rubber products. Hindered phenolic antioxidants are some phenolic compounds with steric hindrance, which have significant antioxidant effects, do not contaminate products, and are widely used. They are currently the main varieties of primary antioxidants.

According to the "2016-2017 China Antioxidants Industry Depth Research Report" released by the New Sijie Industrial Research Center, the antioxidant industry is in an accelerated development stage. Due to the late start of China's antioxidant industry, there is still a gap between the overall level of development of the industry and the international level. The performance is as follows: a single enterprise has a small scale of operation, a shortage of new structural products, poor technical assistance in the application of chemical additives, and industry consolidation. Insufficient degree of production, the product did not form an intensive scale of operation, high-end products, and many product varieties did not form a series. In the past ten years, the Chinese antioxidant industry has developed rapidly. Specialized, large-scale, and technology-based companies have emerged and developed continuously. Some companies have already enjoyed a good reputation in the world. In particular, in the field of anti-aging chemical additives, Chinese companies have formed a trend of competing with international companies in the field of anti-aging by virtue of their late-comer advantages. At the same time, the decentralized development of China's antioxidant industry for many years has created good resources for the domestic excellent companies in industrial mergers and acquisitions, market advancement, and technology accumulation.

Xinsi industry researchers believe that high-efficiency, diversification, compounding, serialization, and environmental protection have become the general trend of the development of the future antioxidant industry.

1. Efficient. Efficient means that the effect is maximized when the additive amount is determined. The main method is the macromolecular quantification of adjuvants. The common adjuvants have a low molecular weight and are easy to volatilize, migrate, and bleed out, which reduces the effectiveness of the additives. The macromolecular quantification can reduce the volatility and migration, and improve the thermal stability and water resistance. Solution capacity, compatibility with materials, so that the effectiveness of additives to give full play.

2, diversification. The diversification of antioxidants not only lies in the emergence of new varieties and the expansion of the application of polymer materials, but also in the diversification of its role. The function of the antioxidant is determined by the structure of its corresponding functional group. On the one hand, the structure of the traditional functional group is continuously improved and perfected, so that the product sequence is continuously enriched. On the other hand, new functional group structure is continuously found, so that the auxiliary agent can play The ways of action are diversified.

3, composite. Compounding is the blend of various antioxidants. The purpose is to make the antioxidant more versatile and enhance the synergistic effect, making the application simple and convenient. Modern compounding technology has not been simple mixed with several additives at the beginning, and has developed into the research and development of multi-component synergistic performance. The research on the synergistic mechanism between the components and the development of synergistic components will be the composite application technology of antioxidants. The key to R&D.

4, serialization. Serialization refers to the analysis and study of the structure and application performance of the same type of auxiliary products. Based on the basic requirements of high efficiency and environmental protection, the same type of new structural chemical additives are designed based on comprehensive technical and economic evaluation. product. Make reasonable arrangements and plans for the main parameters, types, properties, and basic structures of the new series of auxiliary products, so as to coordinate the more reasonable synergy between similar products, supporting products, and target polymer materials, so as to give full play to the The synergies and co-orientation of the agent products achieve better market versatility.

5, environmental protection. With increasingly stringent environmental regulations and the need for sustainable development, environmental protection will become the focus of chemical additives development. On the one hand, it is the development of cleaner production processes for the manufacture of chemical auxiliaries, which are energy-saving and emission-reducing; on the other hand, they are mainly for the development of environmentally friendly auxiliaries that limit or prohibit the use of additives that are toxic to the human body and the natural environment.

With the rapid development of China’s economic development level, the development speed, scale, and technical level of domestic electronic information, automobiles, electronic and electrical, construction, and mechanical fields have been significantly improved. Plastics have great freedom of design, high production efficiency, and light weight. Quality, energy saving and other characteristics have been widely used, and the market demand for new materials such as engineering plastics and special engineering plastics with higher strength, heat resistance, abrasion resistance, and excellent electrical insulating properties than ordinary plastics will increase at a faster rate.
