The greening of rubber additives can be promoted in four aspects

is the general direction of the development of the world chemical industry, but also rubber additives and other fine chemical industry eternal theme. Although after years of efforts, the rubber additive industry has made great progress in clean production, but there are still a small number of products will produce carcinogen nitrosamines, large tonnage products production of clean production process has not yet been popularized, some devices due to environmental pollution problems forced to stop production, production restrictions still occur occasionally. With the improvement of people's environmental awareness, as well as the "gas ten", "water ten", the new "environmental protection law" formal implementation, coupled with the EU REACH regulations brought about by the enormous pressure, "13th Five-Year Plan" period, rubber additives industry greening process must be accelerated. In the author's opinion, the greening of rubber additives can be promoted from four aspects, such as promoting product greening, developing clean production process, promoting effective "three waste" governance model and speeding up the integration of the industry.
Continue to promote the greening of products
At present, the promoter NOBS, anti-age agent D and other large varieties of toxic and harmful rubber additives have achieved a green alternative, but Tyurant, sodium thioamide, PCP and other small varieties have not yet been eliminated. In the future, the focus should be on accelerating the adjustment of the product structure of super-promoters, speeding up the process of industrialization of TBzTD (four-pyrethroids) and replacing TMTD (tetimyl-tetrum) and other autumn lamb products that produce nitrosamines. Among them, Tyuram super-promoter TMTD, TMTM (ithyl methyltylamphetamine) and aminomethylate ZDC will produce carcinogen nitrosamines, the main alternatives TBzTD and TiBTM (ithyl isotretide tyulam) has been gradually industrialized. PCP chemical molybic agents have been discontinued in countries such as Europe and the United States, and their main alternative is DBD (2,2'-dibenzene-diphenyl disulide). Production technologies for these alternatives have been successfully developed in the country and will need to be strengthened in the future. Developing key technologies for clean
the development and implementation of clean production routes are important measures to ensure that rubber additives are environmentally friendly in the production process. In recent years, the clean production technology of oxygen oxidation production NS, the production technology of high thermal stability insoluble sulfur yellow, the rubber additive products of tons of clean predistress, and the clean production process of M, the production promoter of traditional acid-base method, have made breakthroughs in realizing waste water-free discharge. However, M's wastewater problem, which is both a promoter and can be used as a raw material for many promoters, has not been fully solved, and the technology of non-wastewater discharge has yet to be widely popularized. In addition, the secondary sulfonamide promoter and DM product oxidation process, NS oxygen oxidation process, DM hydrogen peroxide oxidation process and other clean production process, although has been successfully developed, but also to be promoted. Promote the "three waste" treatment model
promoter as the representative of rubber additives, its wastewater is mostly high salt, high COD, high resin wastewater. At present, the mainstream water treatment method has many effect evaporation or MVR evaporation, bio-chemical treatment, catalytic oxidation method, adsorption method and so on. However, it turns out that many wastewater treatment methods can not get good results in practical application. Salty wastewater generally evaporates and desalinates first, and then evaporates water for bio-chemical treatment; Difficult biosis can be improved by catalytic oxidation and other methods, and then into bio-chemical treatment. Deep treatment can be used activated carbon adsorption or sand filtration, etc. to bring the water out to meet the standard. Among the existing treatment methods, "multi-effect evaporation or MVR evaporation plus bio-chemical treatment" is the most effective treatment. However, there are still few enterprises in the industry with the processing device at the same time, and they need to speed up the promotion and use in the industry. Speed up the integration of the
because of the promising prospects of rubber additives, in recent years, the rapid expansion of domestic production capacity, market competition will tend to white heat. Many small-scale, single varieties and no raw materials supporting rubber additives enterprises will gradually be inundated in the wave of green chemical industry, large-scale, intensive business model will become the future rubber additives industry adjustment and layout trend.
