Abstract
The invention relates to an oxidation and corrosion inhibitor for lubricating oil. The oxidation and corrosion inhibitor is prepared from the following raw materials in parts by weight: 3-7 parts of bis(salicylidene)propanediamine, 2-6 parts of calcium acetate, 6-10 parts of alkyl succinimide, 4-8 parts of pentaerythritol, 3-7 parts of a solubilizer, 4-6 parts of neutral oil, 0.5-3 parts of calcium oxide, 4-6 parts of n-octane, 1-5 parts of calcium hydroxide, 5-7 parts of methylsilicone oil, 2-4 parts of linoleic acid and 0.5-2 parts of a dispersing agent. By adopting the oxidation and corrosion inhibitor for lubricating oil disclosed by the invention, a film capable of preventing from being abraded and having very strong adsorption capability on metal can be formed on the friction surface under the condition of a medium load and a tight adsorption film can be formed on the interface of the metal and oil to isolate the erosions of water, moisture and the acidic substances.
Description
Technical field
The present invention relates to a kind of lubricating oil oxidation and corrosion inhibitor.
Background technology
Before the eighties, the additive raw material of China's blended lubricating oil is all single dose substantially, namely according to the specification of quality of adjusted oil product, selects the base oil of certain character and adds the additive single dose that some can improve a certain oil property.Because quality of lubrication oil class is lower, oil property evaluation requires also fairly simple, so widely used the blending technology of single dose raw material.Lubricating oil additive concept is one or more compounds added in lubricant, obtains certain new characteristic or improve more existing characteristics in lubricant to make lubricant.Additive divides by function types such as mainly containing antioxidant, anti-wear agent, friction modifier (having another name called oiliness improver), extreme-pressure additive, purification agent, dispersion agent, froth suppressor, corrosion prevention rust preventer, flow point activator, viscosity index improver.Lubricant can form film at friction surface under light load and moderate duty condition, prevents the ability of wearing and tearing.As: sulfuration grease, phosphoric acid ester, metal dithiophosphate.
Summary of the invention
For the deficiencies in the prior art, technical problem to be solved by this invention is, a kind of lubricating oil oxidation and corrosion inhibitor is provided, film can be formed at friction surface under moderate duty condition, prevent the ability of wearing and tearing, have very strong adsorptive power to metal, can metal and oil interface on be formed closely adsorption film with the erosion of isolated moisture, moisture and acidic substance.
For solving the problems of the technologies described above, the technical scheme that the present invention takes is, a kind of lubricating oil oxidation and corrosion inhibitor is made up of the raw material of following parts by weight:
Two salicylidene propylene diamine 3-7 part, calcium acetate 2-6 part, alkyl succinimides 6-10 part, tetramethylolmethane 4-8 part, solubilizing agent 3-7 part, neutral oil 4-6 part, calcium oxide 0.5-3 part, octane 4-6 part, calcium hydroxide 1-5 part, methyl-silicone oil 5-7 part, linolic acid 2-4 part, dispersion agent 0.5-2 part.
The invention has the beneficial effects as follows, lubricating oil oxidation and corrosion inhibitor of the present invention, film can be formed at friction surface under moderate duty condition, prevent the ability of wearing and tearing, have very strong adsorptive power to metal, can metal and oil interface on be formed closely adsorption film with the erosion of isolated moisture, moisture and acidic substance.
