A kind of urea gas phase slowly-releasing slushing oil and preparation method thereof
Technical field
The present invention relates to a kind of volatile rust preventive oil, belong to the metal rust preventing technical field.
Background technology
The corrosion of metal problem spreads all over the national economy all trades and professions, and the 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, it is annual because the direct economic loss that corrosion of metal causes 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 reaches more than 36,000,000,000 yuan at least, 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 present modal means of defence.But existing slushing oil all is comprised of base oil and oil-soluble inhibitor, can only play the antirust function of contact, does not reach the position of slushing oil for those, then can not form effective corrosion protection.And vapor phase inhibitor technology is one of present non contact metal rust-proofing method.It is to utilize vapour-phase inhibitor automatically to volatilize at normal temperatures to give vent to anger
Body forms protective membrane in the metallic surface, plays the effect that suppresses metallic corrosion.During the World War II, because the antirust needs of armament equipment, vapor phase inhibitor technology begins 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 some large enterprises are widely used in antirust in metal product production, transportation, use and the storage process with vapour-phase inhibitor.
The present invention makes a kind of volatile rust preventive oil with base oil and the combination of a kind of oil soluble vapour-phase inhibitor because this slushing oil contains vapor phase inhibitor, thereby when rust-proof seal, oil be stained with less than the position also owing to 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 purpose of this invention is to provide a kind of urea 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 there is antirust function more.
Technical scheme of the present invention is as follows:

The test of salt water logging pool | Qualified | SH/T0025-1999 |
Humid heat test (10d) | Qualified | GB/T2361-1992 |
2, the slushing oil performance test of volatile rust preventive oil
(1) static state does not contact accelerated test
With the volatile rust preventive oil of the present invention of 5ml and 10ml, be placed in the small beaker respectively, with metal testing plate (50mm * 25mm * 2mm) processes by the method for GB/T4879-1999 regulation and is placed in the device, room temperature teleblem 24h, electrolyte solution contains respectively HCO
S-1000mg/L, SO
4 2-2500mg/L, C1
-1500mg/L puts into large burning bosom, and electrolyte solution is remained 40 ℃.In addition, do not put slushing oil as the test of blank.Test-results is shown in Table 2.
Table 2 static state does not contact the accelerated test result
Corrosion all appears in the steel class test piece 1h without slushing oil as shown in Table 2, variable color and corrosion also appear in brass, zinc-plated, chromium plating 2h, and when 5ml slushing oil of the present invention is arranged, no matter be all to rise appreciably the test piece of steel class or antirust time of other test piece, and rust-proof effect is more obvious when 10ml slushing oil of the present invention is arranged.This slushing oil of the present invention has the volatile rust prevention effect.Thereby do not contact accelerated test by static state, show that volatile rust preventive oil of the present invention has good rust-proof effect to many metals.
(2) salt fog cabinet accelerated corrosion test
Test method is with reference to GJBI45A-1993 and SH/T0081-1991.After three metal testing plate 50mm * 25mm * 2mm being pressed the method processing of GB/T4879-1999 regulation, stand-by.To shake uniform 500ml slushing oil sample, remove the specimen surface bubble, and adjust its temperature in (23 ± 3) ℃, with suspension hook 1min is vertically immersed in clean test piece, then mention extension on the top of the shelf with the speed of about 100mm/min, then test piece is hung over relative humidity below 70%, temperature (23 ± 3) ℃ drains 24h without direct sunlight and the little clean place that ventilates.And then get three same metal testing plates and do blank test, the oil of blank test is No. 120 solvent oils.
The spraying salts solution of test usefulness is 5% sodium chloride solution, and test temperature is 35 ℃, spraying 3min, and interval 5min, salt fog sinkability are 1~2ml(80cm
2H).Test-results is shown in Table 3,
As shown in Table 3, the transformer that does not add the oil soluble vapour-phase inhibitor compares, and this slushing oil has fine contact rust-proof effect, and salt spray corrosion resistance is better, and various metals is all had good effect.
Table 3 salt fog cabinet accelerated corrosion test result
Conclusion: do not contact accelerated test and salt fog cabinet accelerated corrosion test by static state, it is good antirust to show that this volatile rust preventive oil has, have again excellent contact rust-proof effect, thereby it can be widely used in the antirust of the inner chamber such as mechanical means or other contact or non-contacting metal.
