Embodiment
In order to make technique means of the present invention, creation characteristic, reach object and effect is easy to understand, below in conjunction with specific embodiment, further set forth the present invention.
Embodiment
1. the selection of base oil
Consider that oil require has certain volatility, and can be compatible with lubricating oil, the base oil of hydrocarbon solvent D60 as it selected.
2. the selection of rust-preventive agent
Volatile rust preventive oil had both required liquid phase good antirust property, required again volatile rust prevention performance to touch the mark, the water substituting that also will have can and acid in and performance.Therefore selecting will to consider when rust-preventive agent antirust to black and non-ferrous metal, consider again other performance.Select black and non-ferrous metal all to have additive dinonyl naphthalene sulfonate barium (Hangzhou Refinery T705 technical grade) and petroleum sodium sulfonate (Hangzhou Refinery T702 technical grade) and dodecenylsuccinic acid (WUXI SOUTH PETROLEUM ADDITIVE Co., LTD. T746 technical grade) composite the examine or check water substituting energy stronger with water yield displacement performance of better rustless property for this reason, compositely the results are shown in Table 1.
The selection of table 1 water displacement rust-preventive agent
| Formula number | T705/% | T702/% | T746/% | Water displacement test |
| 1 | 5 | 5 | 0.2 | Defective |
| 2 | 5 | 5 | 0.4 | Defective |
| 3 | 5 | 5 | 0.6 | Defective |

| 7 | 2 | There is rust qualified |
| 8 | 2 | Rustless qualified |
| 9 | 2 | Rustless qualified |
| 10 | 2 | Rustless qualified |
As seen from Table 2, the result of No. 8 No. 9 No. 10 formulas is all qualified, and No. 8 formulation cost is lower, preferably No. 8 formulas.
The selection of 4 vapor phase inhibitors
The vapor phase inhibitor of metal has carbonic acid bicyclohexylamine (the analytical pure AR of Shanghai new peak chemical reagent company limited level) and nitrous acid bicyclohexylamine (the analytical pure AR of Shanghai new peak chemical reagent company limited level).
The oil soluble of nitrous acid bicyclohexylamine is poor, because ethanol (Shanghai brilliance chemical reagent factory AR level analytical pure) has solublization to dodecenylsuccinic acid (T746 of WUXI SOUTH PETROLEUM ADDITIVE Co., LTD. technical grade) and nitrous acid bicyclohexylamine, adopt ethanol to make solubility promoter, the test-results of volatile rust prevention is in table 3.
The test of table 3 volatile rust prevention
From the volatile rust prevention stand the test of 3, No. 18 formulas of watch test, without precipitation.
According to above 3 tests, determine that composition and the scope of formula is as follows: (massfraction %)
The preparation method of machinery seal vapor phase anti-rust, comprises the following steps, according to mass percent meter:
(1) hydrocarbon solvent 5-88% is dropped into mixed cylinder, heat to 45 degrees Celsius;
(2) T705 dinonyl naphthalene sulfonate barium 3%-15%, T702 petroleum sodium sulfonate 3%-15%, dodecenylsuccinic acid 1%-15% are dropped into mixed cylinder successively, 40rpm stirs 1 hour;
(3) nitrous acid bicyclohexylamine 0%-5% and ethanol 0%-5% are mixed mutually even after, drop into mixed cylinder, 40rpm stir 1 hour, obtain product.
Do the every analysis of experiments of machinery seal vapor phase anti-rust, the results are shown in Table 4
The analysis of table 4 machinery seal vapor phase anti-rust
Product application test-results shows, machinery seal vapor phase anti-rust has reached the requirement of slushing oil JB-4050 quality index.And after using, prove that this product rust-preventing characteristic is good, volatile rust prevention performance is strong compared with like product, has solved the blind hole of sealing equipment, and dead angle etc. does not reach the place of slushing oil, easily oxidation, a difficult problem of getting rusty.And construction is simple, and cost is lower.
