Rubber antioxidant additives RD problems

After the accession to the WTO, China's rubber chemicals industry is no longer a face in the traditional sense of both domestic and foreign markets, but the world's largest integrated market, the world's understanding of the rubber chemicals developments and trends closely follow the trend of international development, China's rubber chemicals industry is very necessary and important. Although China's market demand, RD antioxidant potential, but because of the quality of domestic products abroad, compared with the gap between the great cause of many domestic antioxidant RD serious shortage of equipment operating rate, so the formation of the domestic production capacity, small-production situation, and the market Demand for the formation of great contradictions. In view of the antioxidant RD production industry market conditions and opportunities for development, I think: China's antioxidant RD industrial synthesis of the need to improve and enhance the quality, scale and at the same time increase the application of propaganda, in order to promote the antioxidant RD Production and development. China's production of antioxidant RD industry should focus on the following questions:

1, to accelerate advances in industrial technology, improve product quality

Antioxidant RD prevalent in China because of low-dimer, the product of impurities, such as poor quality of the internal problems in the use of radial tire is limited, we can see the current antioxidant RD key does not lie in the expansion of production capacity, but Improve product quality inherent. Despite the two-step antioxidant RD excellent quality but low-yield, high consumption, a long line of technology, equipment, the large number of serious environmental pollution, resulting in higher product costs, it is difficult to win the market and therefore increase the synthesis of one-step process to improve, by To improve the product quality is critical. One-step production process of antioxidant RD line, the first step to remove condensation, significant improvements are: First, the use of toluene, and toluene in the production of antioxidant RD play multiple roles, such as dehydration used as a solvent, and so on, a So that the smooth-reaction, reaction conditions, easier to control, at the same time re-use of recyclable toluene; II is a single function and the use of better understanding on the formation of a means of controlling their production, be able to recover, reuse of the dynamic cycle routes . Synthesis of antioxidant RD focus on how to improve the content of dimer, and reduce the amine polymer content is generally believed that the production quality is only as good antioxidant RD, the most affected by the condensation reaction. Antioxidant composition of the RD complex, according to information reported to contain a total of 5O substance, a more complex reaction mechanism. Therefore, the relevant mainland authorities should be fully aware of the reaction mechanism and constantly optimize and improve the synthesis and improve the content of dimer. Reducing impurity, to produce high-quality antioxidant RD, in order to meet the needs of tire.

2, the realization of large-scale, series production, enhance economic efficiency

Antioxidant RD synthetic raw materials needed for aniline, acetone, the public are organic chemical products, not the source of pressure, and the synthesis of simple technology, it was decided that antioxidant RD is not a high-value-added products, but in the size and serialization Products to obtain cost-effective products, while China's production capacity of antioxidant RD small current size of the majority of antioxidant RD in the 1000t / a or so, there is no economies of scale, production costs can not compete with foreign advanced level of competition. Therefore, domestic enterprises to improve the synthesis process on the basis of antioxidant RD to speed up the process of the size of new or extended device the size of the minimum in the 5000t / a, a conditional construction companies to l million t / a unit level.

3, step up publicity to promote market demand

With the global economic integration process, rubber additives and Industry will also internationalized. According to the trend of international market development, China will continue to adjust product mix, domestic antioxidant antioxidant and a small mission at any time will be the end of the day, the antioxidant RD manufacturers should vigorously promote the product, a good antioxidant and old age Ding agent alternatives with a view to promoting the antioxidant RD demands of the market.

4, domestic enterprises should aim at international markets and increase export volume

At present, the international market antioxidant RD big gap, and our research and development has attracted the attention of the world rubber industry, China has become the world's major exports RD antioxidant power, China's accession to the WTO to the domestic industry with the production of antioxidant RD To a good opportunity for development. Along with antioxidant RD synthesis technology to improve quality and increase our focus on RD in the domestic market, it is also necessary to speed up international markets, in particular, pay attention to Russia, India, the Middle East Rubber additives such as the production of weak demand growth gradually The regions and countries.

5, a means of improving the detection analysis, in order to open up the market to provide protection

For a long time attached great importance to domestic non-synthetic antioxidant RD process and product quality testing analysis, synthesis process and product quality analysis is not only to provide quality data, but can promote the synthesis of improvement. Home is usually only vague to provide products and softening point average relative molecular weight, and the antioxidant RD is the main active ingredient dimer levels as a result of modern analytical instruments and means of strengthening the domestic should attach great importance to the middle of control and product analysis , The use of advanced scientific and effective analytical instruments analyze the content of the product's active ingredient and impurities in the type and quantity in order to promote product quality.

6, it is necessary to develop, but also to strengthen macro-control efforts to prevent the emergence of excess production capacity and the situation

At present, the antioxidant RD has been unable to meet the demand of the market situation is expected to meet the demand in a certain range will continue for some time, and people with the improvement of living standards, which demand situation may be further strengthened. At present, many domestic enterprises are investing in the construction of production plant or expansion of existing devices to carry out reform, the state must strengthen macro-control, rushing headlong into mass action to prevent the emergence of excess production capacity and output. And excess production capacity is bound to lead to excessive competition, falling prices and declining effectiveness. China's rubber chemicals industry on this issue has a deep understanding of antioxidant RD market has also experienced the Asian financial crisis, after a long market slump, was once the product at a loss.
