A kind of corrosion resistant slushing oil
Technical field
The invention provides a kind of slushing oil, particularly a kind of slushing oil of corrosion-resistant, salt spray resistance belongs to technical field of lubricating oil.
Background technology
Slushing oil is take lubricating oil as base oil, adds therein rust-preventive agent and some and improves additive and make.Usually slushing oil can be divided into displacing type rust preventive oil, lubricating type rust preventing oil, solvent cutback rust preventing oil etc.
Wherein, lubricating type rust preventing oil is the main slushing oil kind of China, and its use range is very wide, and it is inner antirust to be mainly used in machinery, can be used for after rust-proof seal and the unpacking immediately lubricated the use.In addition, this product also goes for the antirust and lubricated usefulness of the operation friction working face of various machineries, and especially, the friction position on harbour machinery, ship machinery is widely used, such as wireline etc.
But the common deficiency of this class lubricating oil is, and is corrosion-resistant, endurance quality is bad, the phenomenons such as after having used for some time, the lubricating oil on surface hardening occurs easily, comes off, cracking.On harbour, boats and ships, its deteriorated process is accelerated in the easier impact that is subject to salt fog.If when being coated with rust preventive lubricating oil thicker, can affect its lubricant effect again, can't reach desired performance.
Summary of the invention
For above commentary to prior art, technical problem to be solved by this invention is: the problem that the erosion resistance of rust preventive lubricating oil, weather resistance are short, and the technical scheme of employing is:
A kind of corrosion resistant slushing oil, include following component by weight: 300~450 parts in mineral oil, 5~10 parts in polymethyl acrylic acid 14 fat, 15~20 parts of polyolefine, 2~3 parts of barium mahogany sulfonates, 2~3 parts of dinonylnaphthalene sulfonic acid calcium, 20~30 parts of oxidized petrolatums, 20~30 parts of methyl-silicone oils, 1~2 part of alkylthio zinc phosphate, 1~5 part of Ursol D, 1~5 part of 2,6-di-t-butyl-4 (dimethyl aminomethyl) phenol, 2~4 parts in lanolin, 3~6 parts of dibutyl phthalates, 3~6 parts of sad dicyclohexyl amines, 1~3 part of epoxy polyaniline, 1~2 part of calcium dodecylbenzene sulphonate, 2~4 parts of dibutyl succinates, 30~50 parts of hydrogenated castor oils, 15~20 parts of hydrogenated styrene-diene copolymer, 3~5 parts of magnesium borates.
Above-mentioned mineral oil is preferably from paraffin base mineral oil; More preferably, be No. 39 machine oil.
Above-mentioned polyolefine is preferably from PAO4.
Barium mahogany sulfonate and dinonylnaphthalene sulfonic acid calcium play a part antirust; Alkylthio zinc phosphate, Ursol D, 2,6-di-t-butyl-4 (dimethyl aminomethyl) phenol is antioxidant; The collocation of methyl-silicone oil and lanolin plays a part to improve lubricity; Hydrogenated styrene-diene copolymer plays a part to adjust the lubricating oil viscosity; That the epoxy polyaniline plays a part in lubricating oil is anticorrosion, anti-salt fog; Dibutyl succinate is dispersion agent, makes that component is uniformly dispersed in lubricated preparation and the storage process, does not produce caking and precipitates; Magnesium borate is extreme pressure agent.
The preparation method of above-mentioned slushing oil is:
S1: in reactor, add mineral oil, warming while stirring to 120~130 ℃;
S2: add while stirring polymethyl acrylic acid 14 fat, polyolefine, barium mahogany sulfonate, dinonylnaphthalene sulfonic acid calcium, oxidized petrolatum, methyl-silicone oil, alkylthio zinc phosphate, Ursol D, 2,6-di-t-butyl-4 (dimethyl aminomethyl) phenol, lanolin, dibutyl phthalate, sad dicyclohexyl amine, epoxy polyaniline, calcium dodecylbenzene sulphonate, dibutyl succinate stir 2~3h;
S3: cool to 40~50 ℃, add while stirring hydrogenated castor oil, hydrogenated styrene-diene copolymer, magnesium borate, continue to stir 2~3h, filter, and get final product.
Slushing oil provided by the invention has good lubricity, and antiseptic property also is better than like product.Weather resistance in the salt-fog test can reach 108 days, and the weather resistance in the warm test can reach 30 days.
Embodiment
Prepare each component by the weight ratio shown in the table 1.
The weight proportion of table 1 embodiment 1~embodiment 3
Above-mentioned mineral oil is No. 39 machine oil.
Above-mentioned polyolefine is PAO4.
The preparation method is as follows:
Embodiment 1
S1: in reactor, add mineral oil, warming while stirring to 120 ℃;
