The metal corrosion widespread metal corrosion loss is very alarming . Prevent metal corrosion is an important work , metal coating solvent diluted anti-rust oil pathway is one important way to prevent metal corrosion , particularly metal products sealed , solvent dilution of anti-rust oil to prevent corrosion material . Since the sixties of the last century , our researchers invested a great deal of effort to study , has been developed the subdural and soft film two series solvent diluted anti-rust oil , and the practical application of metal rust . Solvent dilution of anti-rust oil is an easy-to-use products with excellent anti-corrosion effect , but it is facing environmental problems. The solvent dilution rust preventive oil from oil-soluble corrosion inhibitors , film-forming materials , a base oil and a large amount of solvent . Currently, the market solvent dilution antirust oil generally contains more aromatic hydrocarbon compound and a large amount of heavy metal ions , which is diluted with a solvent used in the anti-rust oil solvent contains aromatic compounds , such as a soft film with a # 200 solvent oil aromatic content in the range of 5% to 15 % , the content of aromatics in the dura mater 120 # solvent oil in the range of 4% to 6 % ; the solvent dilution rust oil used the oil - soluble inhibitor containing heavy metal ions , such as oil - soluble corrosion inhibitor sulfo barium , lead naphthenate, and these agents have excellent anti-rust performance and large-scale use in the rust preventive oil . Solvent dilution type rust preventive oil on the environment and the human body there is a serious chronic hazards , but has been coming for decades , it did not attract enough attention to . With the social progress and the development of technology , people 's awareness of environmental protection has been strengthened and deeply rooted among the people - centered thinking , especially the developed countries of Europe and the United States increasingly stringent environmental protection , China's exports to these countries, hardware, electronic products have been increasingly stringent checks on these products with anti-rust material stringent environmental requirements , such as the European Union requirements per kilogram of lead content less than 90ppm, barium content of less than 1000ppm , in order to adapt to these new challenges , the paper on solvent
