Rubber accelerator production situation and development trend

First, overseas production and market overview
In 2003 the world's rubber consumption is about 18,000,000 tons / year, according to Xiao rubber chemicals rubber consumption accounts for 4% of the total global rubber consumption about agent Xiao year 720,000 tons, of which about 35,000 promoter Tons. In view of the increasingly competitive global market, the main promoter of foreign manufacturers are constantly being adjusted to suit the current rubber additives and industrial development needs. 2001, the original promoter of the world's largest manufacturer of solid-Partridge, one of the U.S. company l4 million to the price of its chemicals business sold to AEA by the Investment Company controlled by investment group, which renounced the production of rubber chemicals. At present, the world's leading promoter of U.S. manufacturers have a joint Dutch-rich company Franks, the United States Cape Town, the Czech love of the rich Group of Georgia, Germany's Bayer and so on, these four companies have about 80% of the global rubber Additives market.
Franks Fu (Flexsys) is the United States by the Monsanto Chemical Department of rubber and rubber testing equipment and the Netherlands Ministry of Aksu. Nobel (Ak.zo Nobe1) Department of rubber chemicals joint venture to set up 50 to 50 of the world's largest rubber chemicals production company, and its representative to promote products for Santocure TBBS (N-tert-butyl -2 - Benzothiazole Sulfonamide times), Santocure TB. SI (N. two-tert-butyl .2 - benzothiazolyl times sulfonamide) and Perkacit TMTD (tetramethyl thiuram disulfide). Franks rich companies now account for the global rubber chemicals market share of about 25%, in 2001 global sales of 6.5 billion U.S. dollars, possession of the U.S. market share of 35%, 45% market share in Western Europe's share, the company will The shift in emphasis in the future development of the Asia-Pacific region, plans to close down the British-based promoter M (2 - mercaptan MBT), DM (disulfide-dibenzothiophene), in Malaysia, the construction of insoluble sulfur production unit, also plans to In mainland China and Southeast Asia to promote cooperation in construction equipment agent.
U.S. companies Compton (Crompton) of the rubber chemicals business in 1996 to buy an American company unilever Luo Yier part of the global rubber chemicals market, the company's products account for about 10% to 15% of the share of representation Product promoter TBZTD (IV benzyl thiuram disulfide) and the CBBS rN. Central has been based. Double. (2 - benzothiazolyl) sulfonamide times, and so on. Compton in 2003 in Zhenjiang in China to establish Compton Danyang Chemical Co., Ltd., the main promoter of the compound and carry out granulation, the scope of sales for the Asia-Pacific region, in order to strengthen the competitiveness of the Asian region, and CommScope Dayton in Italy, South Korea, Thailand and China Taiwan have rubber chemicals manufacturer.
Czech love cell-rich group (Agrofert) is the Czech Republic's largest chemical company in recent years, the company's rubber chemicals business has developed rapidly to become the world's four major new production of rubber chemicals supplier of one of its promoters and the benzodiazepine Amine antioxidant accounts for 1 5% of the global market share of its promoter sulfide CBS (N. Central has been the base -2. Benzothiazole times sulfonamide), TBBS major suppliers Goodyear, pass Secretary Li Pu, Mitch Lin, the world famous Pirelli tire manufacturer, and in 2003 set up an office in Beijing, China, the main chemical products sales of the group.
Germany's Bayer has a long history of large-scale chemical manufacturing company, is the world's leading manufacturer of rubber chemicals, rubber chemicals its product range to supply almost all varieties of rubber chemicals products, accounting for about a global market share The 20% 25OA about the company's subsidiary Rhein Chemie is one of the first building in China's foreign joint venture manufacturer of rubber chemicals. Also new on-meat too, live in complex chemistry, chemical engineering, such as South Korea Kumho is the world's more influential rubber chemicals manufacturers and suppliers.
With the Asian region, hard rubber processing industry by its rapid poor), promoter of the current market focus gradually to the Asian region in particular China and South-East Asia regions, the global demand for rubber to promote stability in the long agent. Average annual growth rate of about 4% to 5%. Among the European countries and regions, Jiang was about 2% to 3%, while growth in the Asian region as much as 8% to 10% = promoter consumption in the United States, see table 1. Xi West, South Korea and China Taiwan consumption, see table 2 Japanese consumption of table 3.
At present, promoters of the world gradually moving to the development of environmental protection, and centralized functions. From a technical point of view. In recent years, some of the international promoter in rubber processing, easy to produce harmful nitrosamines promoter of the toxicity of Punic asked more and more emphasis on this aim in view of the world's former number of restrictive laws and regulations following the introduction of caps, Germany as early as 1982 On the promulgation of regulations to control content of nitrosamine, the United States, Japan, France and Britain also have not developed a new type of nitrosamines TBSI, and following the coffin will have to stop using nitrosourea Ying of the promoter. Therefore, the formation of the sulfide to promote environmental protection system, and environmental protection, development and production of a number of new varieties to replace a tumor caused by dangerous products. From marketing, pay more attention to application performance products in the research, development and function throw into confusion to promote Cavity agent masterbatch and pre-dispersion. Compound to increase research and technology to open up to become the major promoter of foreign producers and expand the market occupied one of the main instruments. Global rubber chemicals after years of use, Lang Taosha million. Xu agent varieties of rubber production and application of more and more in the bag, mainly in non-polluting, good performance of some of the varieties above, the main promoter is TBBS, CBS and TMTD, and so on.
Second, domestic production and market
China's rubber industry promoter in the "Eighth Five-Year Plan" and the "Ninth Five-Year Plan" to be inter-Xiang Shu-speed development. At present, not only to meet domestic market demand, and there is a certain amount of rain out. Zhenjiang Thorpe formed a group, the Northeast before the plant agent, an organic chemical factory in Tianjin and other major production base of the 21st century to promote domestic agent Ji show more rapidly. In recent years, setting off a nationwide building boom promoter, the rapid growth of production capacity. According to incomplete statistics. In 2003, China's rubber accelerator cavity of the total production capacity of about 1 foot of 20,000 tons / year or so, the 2003 annual output is about 8 350,000 tons / year. Table 4 for the promotion of China's major rubber producers and varieties: 5 attack our country in recent years, the main promoter of rubber products production: Kunioka oak hills as a result of rapid industrial growth, combined with cup promote Taiwan agent of the box into a simple process, in addition to the above described Production enterprises. In recent years, there are a number of domestic enterprises to invest in building production equipment to promote the agent or agents to promote the production of complex products, such as Shandong Yanggu Huatai Chemical Co., Ltd.. Shandong Sanyi Fine Chemical Co., Ltd.. Additives Qingdao Hua Heng plant in Shandong Branch of the new multi-national chemical company shares. Caio Chemical Co., Ltd. Yixing, Jiangsu, Shanghai, Beijing Chemical Co., Ltd. Sea. Shanghai Yangtze River Chemical Plant, Shanghai Fengxian joint work to help Liu plant. Rabelais smart agent works in Tianjin in 2003, and other agents to promote domestic production of about 83,500 tons or so varieties of the leading promoters M, DM, CBS, TBBS, NOBS, TMTD six varieties such as the production accounted for 88% of the total output, An increase in production. Do not adjust the product mix. But the most obvious is to produce carcinogens nitrite rubber of the meeting Mr Amine sulfonamide NOBS output has been constrained, a slightly downward trend, while the foreign-led primary amines times Sulfonamide accelerator TBBS production growth year after year , 2003 for annual production of 3800 tons, accounting for sub-sulfonamide 15% of the promoter, and so on.
Due to the promotion of China's import and export prices lower doses. Therefore, in the international market with strong competitiveness in exports has been steadily rising. As China's Taiwan-funded wholly-owned by Canadian Tire plant construction. Each year to import a considerable number of high-performance, environment-friendly varieties to meet the promoters of domestic demand in recent years to promote China's export agent in table 6 due to the Customs statistics vary, according to the China Rubber Association statistics, each in 2003 to promote China's export volume of more than 2 agent More than 10,000 tons. On the price front, and promoting domestic production capacity to avoid large doses, competition in the domestic comparison strong enough in the mid-20th century, since the manufacturer is not much room for profit. Therefore, even though in recent years to promote agent with the price of raw material price fluctuations and dynamic cross, but on the whole remain relatively stable situation, with the prices of raw materials in 2004. Promoter prices also rose. However, a smaller increase. Due to the high price of raw materials refuse to run. Promoter profit margins continue to compress, resulting in a number of small and medium-sized enterprises and management more difficult.
C Vulcanized environmental protection system and the establishment of the development of new varieties
In recent years, some of the international promoter in rubber processing, easy to produce harmful nitrosamines promoter of the toxicity of the growing problem of great importance, the formation of nitroso compounds, such as the impact of research in the world rubber accelerator in the field of hot spots Topic. Therefore, the new rubber accelerator also produce nitrosamines as an alternative promoter of the species. At present, foreign study shows the potential of nitrosamines TBSI about amino acid salts, such as PZ, ZDC, ZDBDC (dibutyl disulfide-A zinc), NBC (dibutyl disulfide amino acid nickel) and so on; Mr Amine sulfonyl times as NOBS, DIBS (N, N. Diisopropyl MBT .2. Sulfonamide times), DEBS (N, N. diethyl .2. Benzothiazole times sulfonamide ), And so on; thiuram categories such as TMTM, TMTD, TETD, disulfide tetrabutylammonium Autumn Lamb (TBTD), and so on; Dithio amines such as DTDM (Dithio-morphine) and so on; dithio carbamoyl methyl times Lactams such as OTOS (N. Oxygen Alliance II ethylene sulfide carbamoyl-N. Oxygen Alliance at the Second Asia-methyl-ethyl). In view of the world, many restrictive laws and regulations were introduced, such as Germany as early as 1982 on the promulgation of regulations to control content of nitrosamine, the United States, Japan, France and Britain also have not developed a new type of nitrosamines TBSI, one after another and stop Will have the use of nitrosamines TBSI. 1997 Beijing Rubber Research and Design Institute analysis determined that the tires in Europe and the United States has been less than Puzhuo Morpholine residue traces, which will have to confirm some of the nitrosamines as NOBS, and other promoters in Europe and the United States no longer used.
Sulfonyl meeting which Mr Amine promoter of alternative varieties are TBBS, TBSI, CBBS, and so on; agents thiuram to promote alternative types of species, such as for TBZTD; dithiocarbamate salts promoter of alternative species for ZBEC (II Benzyl dithiocarbamate A zinc), and so on; DTDM commonly used and is OTOS secondary amine-based sulfur-cross-linked to give an alternative system for the species DuralinkHTS (hexamethylene. Double. Thiosulfate) and Perkalink900 [ 3. (N-methyl-Ning to Kangma) benzene]. Therefore, the above-mentioned by some alternative species for the future Granville rubber accelerator development needs of species.
In addition to the above described promoter worthy of development and environmental protection of new varieties, such as the United States also Van. derbilt developed ISObatyl Tuods (isobutyl disulfide tetramethyl thiuram); Goodyear of the United States has developed a OTTOS (N. oxygen support diethyl amino acid S-N. tert-butyl times sulfonamide ) And the ISO. baty
