In 2002, the output of antioxidants of major domestic enterprises was 36,000t, and the leading varieties were antioxidants RD, 4010NA, 4020, etc. Compared with 30,000t and 33,000t in 2000 and 2001, the output increased steadily: It is estimated that in 2003 the domestic rubber antioxidant The output of accelerators will reach about 40,000t: the total domestic output of accelerators in 2002 is about 75,000t, and the main varieties are accelerators M, DM, CBS, TBBS, NOBS, TMTD, etc. The output of these six varieties accounts for 92% of the total output. In 2000 and 2001, the 46,000t and 70,000t have increased substantially. According to incomplete statistics, the total domestic production of accelerators reached 80,000t in 2003, showing a good growth momentum. Due to the poor level of domestic rubber processing aids, quite a few varieties rely on imports, and domestic output grows slowly, basically maintaining at the level of 10,000t/a. In recent years, the output of rubber additives in my country has grown at an average annual rate of about 10%, but it still cannot meet the domestic demand, especially because the pace of domestic tire joint ventures and cooperation has accelerated in recent years, and some wholly-owned tire enterprises are still under construction, so the import volume The number of antioxidants has increased significantly. Most of the imported anti-aging agents are p-phenylenediamine and quinoline varieties with excellent performance. Since most of the domestic export varieties are traditional varieties, they have maintained a relatively stable trend for many years. Since 2002, due to the recovery of the rubber industry in my country's neighboring countries With the development, the export volume has increased to a certain extent;

Due to the relatively low price of accelerators in my country, they have strong competitiveness in the international market, and exports have been increasing steadily. To meet domestic demand, according to the statistics of industry experts, since many domestic accelerators are purchased by domestic joint ventures to prepare rubber masterbatch for export, the export volume in recent years is much higher than the customs statistics. It is conservatively estimated that domestic accelerators were estimated in 2002. About more than 7000t, it is expected that in 2003 will be higher than in 2002.

At present, my country still needs to import a considerable amount of rubber antioxidants and accelerators to meet domestic demand, and imports are showing a steady upward trend. To a certain extent, it can be seen that the market demand for rubber additives in my country is increasing rapidly. On the other hand, it also shows that my country's rubber additives industry still has a certain gap in meeting domestic demand and compared with the world level. In terms of exports, domestic antioxidants and accelerators have also increased, which to a certain extent also shows that the quality of rubber additives in my country is improving, and the overall level has improved to some extent. In addition, my country also imports a certain amount of processing aids every year to meet the needs of domestic rubber processing.

Although the domestic production and demand of rubber additives have grown rapidly, the competition is also very fierce. Due to the less difficult and rapid development of accelerator synthesis technology, the competition has been very fierce since the 1990s. In recent years, the price of rice has little room for decline. Therefore, in recent years, the price of accelerators has been stable and decreased, but the decrease is not large: in the 21st century, my country's rubber antioxidants are no longer enough to almost monopolize production, and the competition is becoming more and more fierce. Considering that the price of the accelerator DM is greatly affected by the price of the accelerator M, the development of the accelerator NOBS is no longer optimistic, and the domestic production and use of the dominant foreign accelerator variety TBBS is less, so the accelerators M, CZ and The three major varieties of TMTD analyze their price trends in recent years, and the three major varieties of antioxidants are currently dominant.
