As everyone knows: use the greasy dirt on the oil type clean-out system clean metal component of machine surfaces such as gasoline, diesel oil, not only wasted a large amount of energy; And toxicity is large, sensitivity response is many; Easily catch fire, dangerous; Also pollute the environment.For overcoming the shortcoming of above-mentioned existence, people are devoted to research, the development and application of water base metal cleaning agent, with displace oil Base Metal clean-out system.
Existing water base metal cleaning agent prescription is various, and wherein outstanding person is no doubt many, yet along with the develop rapidly of national economy, still can not need and various processing requirement by satisfying the market.For example big machinery enterprise in Xiamen proposes following specification of quality to clean-out system: (1) low bubble.(2) deoiling speed is fast.Be that 60 ℃~80 ℃, clean-out system usage quantity are 5% aqueous solution flushing steel part 3~5 minutes with working temperature, it is clean that its surface reaches.(3) resistance to corrosion is strong, surperficial rustless phase 〉=7 through cleaning day.(4) substantially nontoxic.Existing many metal cleaners.Such as: cleanser 105.It is by fatty alcohol-polyoxyethylene ether 24%, and dodecyl diglycollic amide 24%, polyoxyethylene octylphenol ether 12% and water are formulated.This prescription lacks the cathode type tensio-active agent, with the aqueous solution of its dilution when being heated to 60 ℃~80 ℃, surpasses 61~67 ℃ of the cloud points of polyoxyethylene octylphenol ether, and solution can be muddy, and impact is except speed oil.Simultaneously this prescription also lack the components such as defoamer, inhibiter and oil rub resistance deposition agent [Liu Cheng. the tensio-active agent handbook. Beijing: Chemical Industry Press, 1993:653]; And for example the Germany patent 1,258,529 metal cleaner, and it is by tertiary sodium phosphate 81.25%, potassium bichromate or sodium 12.5%, disodium ethylene diamine tetraacetate (EDTA) 3.125% and tridecanol polyoxyethylene acid 3.125% form.The greatest problem that this prescription exists is to use extremely malicious potassium bichromate or sodium as inhibiter, harmful mankind's health.Problem like that is too numerous to enumerate, and all the chemical constitution because of metal cleaner is unreasonable for they, can not satisfy simultaneously above-mentioned four point mass requirements.
Summary of the invention
The object of the present invention is to provide a kind of high-efficient multifunctional metal detergent prescription, compound method and using method.Not only deoiling speed is fast for this high-efficiency multi-function clean-out system, and the surface through cleaning has good corrosion inhibiting ability, is again simultaneously a kind of low bubble, substantially nontoxic green product.
Technological line and the action principle taked for the purpose that realizes the present invention are as follows:
(1) selection of nonionic surface active agent and action principle thereof:
This product selects the nonionic surface active agent such as alkylphenol polyoxyethylene (OP-10), fatty alcohol-polyoxyethylene ether (AEO-9) and alkylol amide (6501) as the principal constituent of clean-out system.They all are amphiphile, amphiphilic molecules: have oleophilic group and hydrophilic group, soluble in water, unionization in water has the functions such as good infiltration, infiltration, emulsification, diffusion, acid and alkali-resistance, anti-hard water.Yet because molecular structure is different, advantage is separately arranged respectively.The hydrophobic ability of OP-10 is strong.The functions such as AEO-9 and 6501 infiltration infiltration decontamination and anti-hard water are then more outstanding.6501 also have the functions such as anticorrosive and oil rub resistance deposits again concurrently.They are composite, have complementary advantages, and the synergy of generation can improve the cleansing power of clean-out system greatly.
(2) selection of cathode type tensio-active agent and the mechanism of action thereof:
The compound of above-mentioned nonionic surface active agent, because OP-10 and AEO-9 cloud point are respectively 61~67 ℃ and 75~81 ℃, in the cleaning process of heating, solution can be muddy, cleansing power descends.Add the cathode type tensio-active agent and then can effectively eliminate or improve the cloud point of monomer nonionic surface active agent.To adapt to the needs of the situation of heating.Can improve simultaneously the deoiling ability of clean-out system.
Cathode type tensio-active agent commonly used has Sodium dodecylbenzene sulfonate, sodium lauryl tri(oxyethyl) sulfate, sodium lauryl sulphate, sodium laurylsulfonate, triethanolamine oleate etc.Test shows: sodium laurylsulfonate and triethanolamine oleate are more suitable.The former is not used owing to too expensive.Triethanolamine oleate is by oleic acid and excessive trolamine direct reaction and get.
Excessive trolamine remains the important component of clean-out system, and it is tensio-active agent (emulsifying capacity is strong), is again tenderizer, inhibiter, suds-stabilizing agent, or anti-dirt deposition agent again.This be since its molecule in have a plurality of hybridized atom O and N, can with the Ca of the aqueous solution 2+, Mg 2+Chelating makes it softening, also can with greasy dirt in two valency heavy metal ion chelatings, strengthen soil removability, simultaneously it can also with the Fe of steel surface 2+Or exposed iron atom chelating, form chemisorbed film, play rust inhibition.
(3) selection of organic solvent and the mechanism of action thereof:
Organic solvent both can directly be dissolved down greasy dirt, also can increase the solubleness of tensio-active agent, and two kinds of effects can both promote the cleansing power of clean-out system.Through repeatedly comparing, from all multi-solvents such as ethanol, Virahol, propyl carbinol, propandiol butyl ether, ethylene glycol monobutyl ether, pick out ethylene glycol monobutyl ether as the important component of clean-out system.Ethylene glycol monobutyl ether is good solvent, also is good tensio-active agent.It has, and low toxicity, boiling point are high, viscosity is little, can arbitrary proportion and the advantage such as water is miscible.
(4) selection of washing assistant and action principle thereof:
Select anhydrous sodium metasilicate and sodium metaborate as washing assistant.Anhydrous sodium metasilicate is soluble in water, vitrification phenomenon can not appear, in inorganic electrolyte, active alkalinity and the pH value buffer index of Starso are the highest, the effect of stronger moistening, emulsification and saponification grease is arranged, have outstanding performance aspect removal, dispersion and the suspension greasy dirt, and can stop soil redeposition, can with above-mentioned component compatibility.
Sodium metaborate is soluble in water, generates NaOH and HBO in water after the intense hydrolysis 2, be strong basicity.NaOH can make the esterification of workpiece surface greasy dirt, has improved the oil removing ability of clean-out system.And HBO 2Might and Fe 2+Effect generates [Fe-(BO 2) 2] settling; Also may with the trolamine molecule in the amino effect generate the metaboric acid trolamine, this material easily forms chemisorbed film at steel surface, therefore, sodium metaborate is not only washing composition, also is a kind of sanitas.
(5) selection of inhibiter and action principle thereof:
Select the Sodium orthomolybdate of low toxicity to replace extremely malicious potassium bichromate as inhibiter, be conducive to the environment that to protect mankind is depended on for existence.Sodium orthomolybdate is soluble in water.Have oxidisability, it can be the Fe of steel surface 2+Be oxidized to γ-Fe 2O 3, and self is reduced to MoO 2, simultaneously owing to exist two hybridized atom O in its molecule, can with Fe 2+Chelating forms [Fe-MoO 4].Steel surface has just formed by γ-Fe like this 2O 3, MoO 2[Fe-MoO 4] passive film that forms, add the synergistic slow corrosion effect of alkylol amide, triethanolamine oleate, trolamine, water glass, sodium metaborate etc., so this clean-out system has good erosion resistance.
(6) selection of defoamer and action principle thereof:
From various defoamers, select the H-580 silicone antifoam agent as the important component of clean-out system.This be since H-580 have antifoaming speed fast, press down long, good dispersity of bubble time, the advantage such as stability is extremely strong, can work below 100 ℃, and usage quantity is little.Its action principle is: organosilicon has hydrophobic nature, and very easily is adsorbed on the foam, and the local surface tension of liquid film is reduced, and takes away liquid contiguous under the liquid film, causes thinning of liquid film and breaks.
