Description
Technical field
The present invention relates to a kind of volatile rust preventive oil, belong to metal rust preventing technical field.
Background technology
Corrosion of metal problem spreads all over national economy all trades and professions, and corrosion of metal meeting makes the performance of metal products and commodity value be subject to great infringement, even can cause significant trouble and make equipment scrapping.According to statistics, the direct economic loss causing due to corrosion of metal every year accounts for the 2%-4% of total value of production in national economy, calculate with China GDP18.23 trillion yuan Renminbi in 2005, the loss that China causes because of corrosion the whole year at least reaches more than 36,000,000,000 yuan, and its harm is very surprising.For avoiding corrosion, people have adopted multiple technologies and method to prevent the generation of metallic corrosion.Wherein, protecting metal products with slushing oil is one of current modal means of defence.But existing slushing oil is all made up of base oil and oil-soluble inhibitor, can only play the antirust function of contact, the position that does not reach slushing oil for those, can not form effective corrosion protection.And vapor phase inhibitor technology is one of current non contact metal rust-proofing method.It is to utilize vapour-phase inhibitor automatically to volatilize and give vent to anger at normal temperatures
Body forms protective membrane in metallic surface, plays the effect that suppresses metallic corrosion.During World War II, due to the antirust needs of armament equipment, vapor phase inhibitor technology starts application and development.For many years, many developed countries national defence and civilian aspect all adopt in a large number vapour-phase inhibitor to be used for metal rust preventing, product form has volatile rust prevention powder, volatile rust preventive paper, gas phase anti-tarnishing film, gas-phase anti-corrosion paint etc.At industrial circle, abroad vapour-phase inhibitor is widely used in antirust in metal product production, transportation, use and storage process by some large enterprises.
The present invention, by base oil and the combination of a kind of oil soluble vapour-phase inhibitor, makes a kind of volatile rust preventive oil, because this slushing oil contains vapor phase inhibitor, thereby in the time of rust-proof seal, oil be stained with less than position also because the effect of vapor phase inhibitor is protected.At home, the antirust problem of the special gear box of engine, large-scale compressor etc. does not thoroughly solve always.
Summary of the invention
The object of this invention is to provide a kind of urotropine gas phase slowly-releasing slushing oil, this volatile rust preventive oil had both had the rust-preventing characteristic of slushing oil contact, had again the high-performance of vapour-phase inhibitor volatile rust prevention.The present invention can be widely used in the antirust for a long time of weaponry and civilian metallic substance, is mainly used in airtight inner chamber system.Various metals are had to antirust function more.
