Abstract
The invention discloses a novel metal antirust agent comprising triethanolamine, oleic acid, organic phosphoric acid, barium petroleum sulfonate, naphthenic acid, alumina, ethanol and glycerol. The metal antirust agent has the beneficial effects that: a substance which can be dissolved in water at room temperature and can form a film when being met with a ferrous metal is selected, and organic and inorganic antirust components which have good antirust performance and can be combined with the film-forming agent are selected, so that an antirust protective film which is not dissolved in cold water is formed by combining through a compound bridging effect, and auxiliary agents each have a certain synergistic superposition effect of antirust function.
Description
Technical field
The present invention relates to a kind of novel metal rust-preventive agent, belong to chemical field.
Background technology
Ferrous metal is sealed up for safekeeping in production process and finished product, for preventing surface corrosion, must carry out without the antirust processing of application, for example, applying rust remover on surface.Prior art metallic surface is antirust, early uses and has the good slushing oil of rust-proof effect, forms protective oil film by slushing oil in metallic surface, completely cuts off water in air vapour to corrosion of metal, thereby reaches cloudy rust of long period.But use slushing oil, not only need to consume a large amount of oil plant raw materials, aggravate energy consumption, and for example, in following process (weld, paint, electroplate, assemble) and unpacking, all need to clean oil removing, not only produce a large amount of oily waste liquor discharges of cleaning, cause the pollution to environment, and cleaning oil removing is time-consuming, also can increase cost.Slushing oil drawback manifests gradually, and people more and more pursue the water-based antirust agent that the feature of environmental protection is good.
Summary of the invention
The deficiency existing for prior art, technical problem to be solved by this invention is, a kind of novel metal rust-preventive agent is provided, and forms the anti-rust film of good antirust property in metallic surface, antirust validity period is long, and antirust rete is thin.
For solving the problems of the technologies described above, the technical scheme that the present invention takes is, a kind of novel metal rust-preventive agent, and it comprises trolamine, oleic acid, organic phosphoric acid, barium mahogany sulfonate, naphthenic acid, aluminum oxide, ethanol and glycerine.
Optimize, above-mentioned novel metal rust-preventive agent, its trolamine is that 10-18 weight part, oleic acid are that 3.5-4.7 weight part, organic phosphoric acid are that 5-7 weight part, barium mahogany sulfonate are that 4-8 weight part, naphthenic acid are that 2.5-4.6 weight part, aluminum oxide are that 3.5-6.7 weight part, ethanol are that 5-10 weight part and glycerine are 6-8 weight part.
Optimize, above-mentioned novel metal rust-preventive agent, its trolamine is that 17 weight parts, oleic acid are that 4.2 weight parts, organic phosphoric acid are that 6 weight parts, barium mahogany sulfonate are that 5 weight parts, naphthenic acid are that 3.4 weight parts, aluminum oxide are that 5 weight parts, ethanol are that 8 weight parts and glycerine are 8 weight parts.
The invention has the beneficial effects as follows: can be water-soluble owing to being chosen in normal temperature; meet ferrous metal energy filmogen; and the organic and inorganic antirust composition of selecting good antirust property and being combined with membrane-forming agent; be insoluble to the antirust protective film of cold water in conjunction with composition by the bridging action of compound, each auxiliary agent all has the collaborative additive effect of certain antirust function.More existing water soluble anti-rust agent, there is film formation time short, quick-drying is good, 1-2 minute is film forming, film forming absorption firmly, has extremely strong adsorptive power at ferrous metal surface, and normal temperature environment steam can not ooze to metallic surface, thereby thering is good rust-proof effect, actual antirust use can reach 3-6 month non-corrosive; And film forming is thin and fine and close, only 3-5 micron, does not change workpiece apparent, and general workpiece does not need that membrane removal can directly be assembled, application.
Embodiment
The present invention is a kind of novel metal rust-preventive agent, it is characterized in that: comprise trolamine, oleic acid, organic phosphoric acid, barium mahogany sulfonate, naphthenic acid, aluminum oxide, ethanol and glycerine.
The composition by weight of its composition is: trolamine is that 10-18 weight part, oleic acid are that 3.5-4.7 weight part, organic phosphoric acid are that 5-7 weight part, barium mahogany sulfonate are that 4-8 weight part, naphthenic acid are that 2.5-4.6 weight part, aluminum oxide are that 3.5-6.7 weight part, ethanol are that 5-10 weight part and glycerine are 6-8 weight part.
In the time that the composition by weight of its composition is as shown in following, effect is best:
Trolamine is that 17 weight parts, oleic acid are that 4.2 weight parts, organic phosphoric acid are that 6 weight parts, barium mahogany sulfonate are that 5 weight parts, naphthenic acid are that 3.4 weight parts, aluminum oxide are that 5 weight parts, ethanol are that 8 weight parts and glycerine are 8 weight parts.
The invention has the beneficial effects as follows: can be water-soluble owing to being chosen in normal temperature; meet ferrous metal energy filmogen; and the organic and inorganic antirust composition of selecting good antirust property and being combined with membrane-forming agent; be insoluble to the antirust protective film of cold water in conjunction with composition by the bridging action of compound, each auxiliary agent all has the collaborative additive effect of certain antirust function.More existing water soluble anti-rust agent, there is film formation time short, quick-drying is good, 1-2 minute is film forming, film forming absorption firmly, has extremely strong adsorptive power at ferrous metal surface, and normal temperature environment steam can not ooze to metallic surface, thereby thering is good rust-proof effect, actual antirust use can reach 3-6 month non-corrosive; And film forming is thin and fine and close, only 3-5 micron, does not change workpiece apparent, and general workpiece does not need that membrane removal can directly be assembled, application.
Certainly, above-mentioned explanation is not limitation of the present invention, and the present invention is also not limited to above-mentioned giving an example; those skilled in the art; in essential scope of the present invention, variation, remodeling, interpolation or the replacement made, all should belong to protection scope of the present invention.
