Description
Technical field
The present invention relates to field of metal surface treatment technology, the more particularly to preparation technology of multi-function metal antirust agent and should
With.
Background technology
Metal in an atmosphere, can under certain condition occur chemical action or electrochemical action with oxygen, water and other impurities
And produce metal erosion.Particularly be in the metal material between metalworking procedures, because surface-active is high, workpiece processing,
In carrying, checking, air, sweat and contacted with the pernicious gas in air through moisture, make workpiece be easy to produce corrosion,
Finished work is caused to scrap or do over again.In order to prevent metal works corrosion during storing, it is necessary to carry out antirust treatment.
Antirust agent is a kind of synthesis bleeding agent of super grade high efficiency, and it can form thin film in metal surface, prevent metal
Corrosion.According to the difference of component, antirust agent is divided into oil-based rust inhibitor and water-based antirust.Oil-based rust inhibitor is by base oil, oil
Soluble corrosion inhibitor and auxiliary additive etc. are constituted.Oil-based rust inhibitor can form one layer of fine and close oil film in metal surface, and isolation is empty
Water, oxygen in gas etc. play anti-rust action.But oil-based rust inhibitor subsequent handling need to carry out oil removing, the removal difficulty phase of antirust oil
When big, and with the continuous enhancing of petroleum resources growing tension and environmental consciousness, the problems such as be not easily decomposed along with oil
In the presence of oil-based rust inhibitor is gradually substituted.Water-based antirust is by water soluble anti-rust agent, water-soluble additive, corrosion inhibiter and water etc.
Composition.Water-based antirust is to add a certain amount of antirust agent in aqueous, raw to prevent the generation of chemistry or electrochemical action
Anti-rust action is played into insoluble passivation film or reaction film layer.But after this kind of antirust agent is applied to metal surface, liquid film easily trickles, water
After dividing volatilization, also one layer of bloom can be formed in metal surface, lose due rust-proof effect, rustless property does not reach antirust oil
Effect.Also, containing the composition such as nitrite, bichromate traditional water-based antirust, it is well known that nitrites are more
Carcinogen, has harm to the health of operator, while bichromate composition is because containing heavy metals such as chromium, it is harmful to environment,
Have impact on the performance and quality of metal.Even if the novel water-based antirust agent for having partial monopoly file to disclose at present can effectively solve the problem that
Problem in terms of environmental protection, but there is the defect such as not good enough rust-proof effect, unitary function, relatively costly.
The content of the invention
In order to solve the above technical problems, the present invention provides a kind of preparation technology of multi-function metal antirust agent, by specific
Production technology, be aided with Suitable base combination so that the multi-function metal antirust agent impact resistance being prepared from is high, while resistance to
Salt fog time and resistance to copper sulphate time persistently, disclosure satisfy that the requirement of industry, with preferable application prospect.
