The Development Of The Technology of The Rubber Auxiliaries
We rubber auxiliaries industry have already had the base of research and development,and in the future,it still needs progress according to studying with the market demand, enterprises, research institutes and colleges collaborative.
First,to speed up the processing operation system additives industrialization and series of products
China's processing operation system additives start later, its breed is not much, so we need to increase the development efforts. The processing operation system additives though smaller amount, but they have many varieties and miscellaneous, and the technological content is higher, plays an important role in rubber processing industry,improving \ processing technology, improving the production efficiency and product quality.
Even agent used to improve different polarity and viscosity rubber uniformity, Germany S&S. The company, such as chemical company are Rhine series YingShi varieties, domestic has yet to large-scale production. S&S. The company is 40 MSF dark aromatic hydrocarbons mixture of resin, apply to NR, SBR, BR, EPDM, NBR, rubber, and can not only improve different polarity rubber uniformity, and can promote packing quickly dispersion. Its 60 NSF is light hydrocarbon resin fat mixture, apply to light color compound. Visible, to meet the requirements of the strong specificity, need to production series varieties.
Viscous resin is especially suitable for composite multi-layer rubber products, although we had some varieties industrialization in recent years, there are still gaps. If the company BASF Koresin super viscous resin butyl phenolic resin is uncle acetylene, can make the rubber surface viscous kept for weeks, but there is still need to import. In a rubber adhesive cord YongZhuJi, America Cytec company product many in recent years, and the launch of the single component, low cost, no environmental pollution prevention is the bond resin CyrezCRA132 advanced novel since type condensation products, even if in no methylene accept body, them melamine since condensation composition of also can become the cross-linking effect, bond is superior in quality to those HMMM and drill salt products. This new product development train of thought is worth our using for reference.
The processing operation system additives and dispersant, plasticizer, tuomoji, prevent focal agents, all is their own systems of special additives. Dow corning company of silane class tuomoji, spraying agent within the outstanding performance by domestic customers. Nanjing dawn chemical plant developed recently silane coupling agent St-75 four sulfide content low, it is a part of ErLiuHuaWu, reducing coke burning tendency. Changzhou dawn chemical plant has developed between the diffuse a bonding system, and scattered the effect is good. Zhenjiang kingway group Co., LTD develop successful general acid compound metal salt RM series product price low, which is helpful for the user to reduce costs. These products should speed up the industrialization.
Second,age-resistant and promote agent to the development of new varieties, technical to continue
Accelerator and antiager are of the most age-resistant additives, so its production technology progress has been the domestic and foreign research hot spot. Nanjing chemical plant of benzene 2 amine class will age-resistant in technical improvement, the reduction technology production RT hydrogenation which company, reduce pollution and improve quality, so as to the production high quality 4020 and 4010 NA play good raw material base. Muscle class, autumn lamb and times of sulfonylurea cool amine kind of promoting agents are used oxidation process synthesis condensation, the traditional process to use sodium hypochlorite, such as sodium nitrite oxidant, "three wastes" big. Domestic already research and development oxygen catalytic oxidation process, hydrogen peroxide oxidation process, electrochemical synthesis process, "three wastes" is greatly reduced, and comply with the "clean technology" trend of development. Promoting agents of the powder oil filled and granulation techniques already in tianjin and shandong, as to the future, still need to speed up the pace of technical improvement. Different types of promoting agents blends with objects in the foreign sales, can will has cooperative effect variety blends with together to form the performance of new varieties of unique. This is the new products developed in the future.
Since the German 1988 air N-and control nitrate content glue since, countries are to take measures to switch to producers safety promoting agents, in Europe and in the radial tires in recent years has't detect NOBS with the yankees? Lynn promoter composition, "amino accelerator NS and CZ become the dominant accelerator varieties. Our country is the volume NS increased year by year, can completely satisfy the production has CZ market demand, future should continue to promote NS expanding consumption. In addition, the new type safety promoting agents also is still in development in, TBSI function more excellent than NS, nanjing chemical plant, are studied. Should also be developed to two sections for the safety of the raw material cavity promoting agents, and other toxic problems without nitrosamines varieties.
The characteristics of the future should be nontoxic additives and no environmental pollution, price reasonable. If the company's, especially Roy Duravzon 37 with three of the benzene ring of polybenzoxazines two plastic kind of age-resistant, no color pollution, is and the static and dynamic rubber products of oxygen and ozone resistance of age-resistant ideal, with slow, migration resistance, volatile extraction) low advantages.
