Abstract
The invention discloses a micro emulsion type metal anti-rusting liquid and a preparation method thereof. The micro emulsion type metal anti-rusting liquid comprises base oil, an anti-rusting agent, a surfactant, silica sodium, thiourea, sodium metabisulfite, nitrogenous trimethylene phosphoric acid, benzotriazole, myo-inositol hexakis dihydrogen phosphate, vinyl acetate, trimethyl ammonium chloride, methacrylic acid dimethylamino ethyl ester, agar and deionized water. The preparation method comprises the following steps: firstly, mixing the base oil, the anti-rusting agent, silica sodium and thiourea, stirring, heating, subsequently adding myo-inositol hexakis dihydrogen phosphate, stirring so as to obtain a mixture I, further adding the surfactant, sodium metabisulfite, nitrogenous trimethylene phosphoric acid and benzotriazole into the deionized water, heating, adding vinyl acetate, and stirring so as to obtain a mixture II, mixing the mixture I and the mixture II, further adding the rest components, heating, and uniformly stirring, thereby obtaining the anti-rusting liquid. By adopting the anti-rusting liquid disclosed by the invention, the anti-rusting time is prolonged, and the anti-rusting effect is improved.
Description
Technical field
The invention belongs to field of metal surface treatment technology, be specifically related to a kind of micro-emulsion type metal rust protection liquid and preparation method thereof.
Background technology
The corrosion of metal is the problem often run in producing, metal rusting not only makes metal works itself be damaged in profile, color and luster and mechanical property etc., and make the Quality Down of product, especially severe also can make product rejection, China GDP in 2011 is 7.43 trillion dollars, and the financial loss caused because of corrosion is up to 2200 ~ 3,700 hundred million dollars, accounts for 3% ~ 5% of national GDP total value.In order to slow down the corrosion of iron and steel, loss corrosion caused drops to bottom line, and people take a lot of rust protection measure, wherein the use of rust protection liquid be then apply comparatively wide, effect is significantly a kind of.
Rust protection liquid is a kind of synthesis permeate agent of super grade high efficiency, and it can form thin film in metallic surface, prevents corrosion of metal.According to the difference of component, rust protection liquid is divided into oil base rust protection liquid and aqueous protective fluids.
Oil base rust protection liquid is made up of base oil, oil-soluble inhibitor and supplementary additive etc.Oil base rust protection liquid can form the fine and close oil film of one deck in metallic surface, the water in air-isolation, oxygen etc. play rust inhibition.But oil base rust protection liquid subsequent handling need carry out oil removing, the removal difficulty of slushing oil is quite large, and along with the continuous enhancing of petroleum resources growing tension and environmental consciousness, and add the existence of the oil not easily problem such as decomposition, oil base rust protection liquid is replaced gradually.
Aqueous protective fluids is made up of water soluble anti-rust agent, water-soluble additive, inhibiter and water etc.Aqueous protective fluids adds a certain amount of rust-preventive agent in aqueous, to stop the generation of chemistry or electrochemical action, generates insoluble passivation film or react rete and play rust inhibition.But after this kind of rust protection liquid is applied to metallic surface, liquid film easily trickles, after moisture evaporation, also can form one deck bloom in metallic surface, lose due rust-proof effect, rustless property does not reach the effect of slushing oil.Further, traditional aqueous protective fluids is many containing the composition such as nitrite, dichromate, as everyone knows, nitrites is carcinogenic substance, has harm to the health of operator, and simultaneously dichromate composition is because of containing heavy metals such as chromium, to bad environmental, also have impact on performance and the quality of metal.
CN201210582603.8 discloses a kind of Metal surface antirust liquid, and this rust protection liquid is formulated by sodium benzoate, Sodium Nitrite, high polymer composite synergistic activator, ethylenediamine tetraacetic acid (EDTA), tripoly phosphate sodium STPP, xylene, polyoxyethylene glycol, urea, G & W; CN201410000991.3 discloses a kind of micro-emulsion type water-based metal antirust liquid, and this rust protection liquid comprises rust-preventive agent, base oil, tensio-active agent, inhibiter, stablizer, thickening material, pH adjusting agent and deionized water.Although existing a lot of rust protection liquid launch, currently available products all exists the defects such as rust cleaning speed is slow, antirust time is short, working temperature is high, tank liquor unstable properties and rust cleaning to be difficult to thoroughly and the problem such as still to get rusty easily after rust cleaning.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art and provide a kind of micro-emulsion type metal rust protection liquid and preparation method thereof, this rust protection liquid can extend antirust time, improves rust-proof effect.
A kind of micro-emulsion type metal rust protection liquid, comprises with parts by weight: base oil 5 ~ 12 parts, rust-preventive agent 2 ~ 7 parts, 3 ~ 9 parts, tensio-active agent, 1 ~ 4 part, silication sodium, thiocarbamide 2 ~ 7 parts, Sodium Pyrosulfite 2 ~ 6 parts, nitrogen base trimethylene phosphoric acid 3 ~ 9 parts, benzotriazole 1 ~ 5 part, six phosphate ester of cyclohexanhexanol 4 ~ 10 parts, vinyl-acetic ester 2 ~ 7 parts, trimethyl ammonium chloride 3 ~ 6 parts, dimethylaminoethyl methacrylate 1 ~ 5 part, 3 ~ 8 parts, agar, deionized water 8 ~ 15 parts.
