Description
Technical field
The present invention relates to field of metal surface treatment, more particularly to a kind of metal surface treating method of high-efficiency environment friendly.
Background technology
Conventional metal material, corrosion easily occurs during use.Traditional hardware method of inhibiting corrosion is：It is de-
Fat, cleaning, phosphatization and dust.
The Chinese patent of Application No. 201410402437.8 discloses the flowing water of a kind of metal surface pre-treatment and plastic-spraying
The production line balance technique of line production technology, the metal surface pre-treatment and plastic-spraying is able to ensure that metal front surface processing and plastic-spraying
Sequence continuation, linking is in time, it is ensured that plastic-blasting surface color stability, levelling uniformity, surface is clean sliding bright, attachment
Power is strong.But this invention increases the adhesive force of plastic-spraying using phosphatization mode, environment is unfriendly, it is also necessary to which spray coating powder paint is prevented
Rust, cost increase.
The content of the invention
In order to solve the above-mentioned technical problem, the invention provides a kind of metal surface treating method of high-efficiency environment friendly, pass through
Using metal ion liquid rust remover, cost is reduced, improves metal treatment effect, is a kind of gold suitable for industrialized production
Metal surface processing method.
The present invention concrete technical scheme be：The method includes the steps of：
1) clean：Hardware is cleaned with pure water；
2) degreasing：Sprayed with degreasing agent or soak hardware, clean oil removing；
3) derust：Sprayed with metal ion liquid rust remover or soak hardware, remove surface rusty stain；
4) it is cleaned and dried：Hardware is sprayed with clear water, then dry solidification cools down.
Preferably, the metal ion liquid rust remover contains following components：40-55wt% organic acids, 8-20wt%
Metal ion liquid, surplus are water.
Preferably, the organic acid is citric acid or lactic acid.
Preferably, the metal ion liquid is the compound with following structure：
Wherein R1For C1-C4Aliphatic hydrocarbon, R2For C4-C12Aliphatic hydrocarbon, M Cu2+, Mn2+, Fe2+, Zn2+, Ni2+And Co2+
In one kind.
Rust remover in the present invention uses organic acid as main derusting composition, to environment nontoxic pollution-free.But due to having
Machine acid is acid weaker compared to hydrochloric acid or sulfuric acid, therefore adds metal ion liquid as accelerator.Metal ion liquid contains
Hydrophilic polar portion, it also containing hydrophobic nonpolar moiety, can be good at soaking metal surface, help organic acid infiltration,
Promote the progress of descaling process.The cationic moiety of metal ion liquid contains long aliphatic chain simultaneously, can prevent organic acid it
Between mutually assemble, increase active area.N atoms on other imidazole ring contain lone pair electrons, can be coordinated and inhale with metal surface
It is attached, adsorbed film is formed, there is inhibition, therefore function of the formula with extraordinary derusting rust-proofing of the present invention.
Preferably, the preparation method of the chelate type ionic liquid comprises the following steps：

2) one kind added after reaction terminates in divalent metal chloride, bromide, sulfate or nitrate is coordinated
Reaction；
3) one kind in the chlorate of addition cationic containing general formula, Bromide, sulfate, nitrate, passed through
Filter, remove solvent and obtain crude product；
4) obtained crude product is dissolved in organic solvent, then adds isometric water, vibrate 3-10 minutes, static point
Water layer is removed in layer, liquid separation, repeats above step 3-5 times, collects rich ionic liquid body phase；
5) evaporative removal organic solvent, products obtained therefrom vacuum drying 22-26h obtain metal ion liquid.
Metal ion liquid is not soluble in water, but can be with any immiscible organic solvent, therefore rust remover is before use, due to having
Machine acid presence, rust remover is homogeneous solution, and after rust remover use, organic acid is largely consumed, generation metal salt and
After the products such as water, metal ion liquid solubility reduces, and a part of metal ion liquid directly adsorbs in metal component surfaces, does
After dry, at room temperature, the metal ion liquid is solid, can suppress the corrosion of hardware, another part as coating
Metal ion liquid in a liquid can reduce cost with water direct layering with recycling, environmentally safe.
Preferably, the mol ratio of the hexafluoroacetylacetone and ammonia in the step 1) is 1: 1.1-2.
Preferably, the neutralization reaction temperature in the step 1) is 25-40 DEG C.
Preferably, the complexation reaction temperature in the step 2) is 50-80 DEG C.
Preferably, the step 1) or 2) in reaction time be 10-32h.
It is compared with the prior art, the beneficial effects of the invention are as follows：The metal surface treating method derusting rust-proofing of the present invention
Significant effect, raw material is recyclable, and metal surface treating method of the invention simplifies work without phosphatization and the step of dust in addition
Skill flow, reduces production cost and cost of sewage disposal, is a kind of metal surface treating method of high-efficiency environment friendly.
