A kind of water-base emulsion type rust protection liquid and preparation method thereof
Technical field
The present invention relates to antirust technology field, relate in particular to a kind of water-base emulsion type rust protection liquid and preparation method thereof.
Background technology
Metallic surface is antirust is the important topic in industrial production, and traditional rust protection liquid, slushing oil have advantage also to have shortcoming.In common aqueous rust preventive, containing a large amount of Sodium Nitrites, there is carinogenicity, be unfavorable for that environmental protection and the person are healthy, and adopt wetting Agent for Printing Inks to extend the life-span of aqueous rust preventive, bring again the disadvantage of touching with one's hand, being covered with dust, and can not be antirust for a long time; Although it is antirust for a long time that general hard film rust preventive oil is applicable to, film forming is also transparent attractive in appearance, and water white resin kind is less, and unstable also easy oxidation discoloration, also needs organic solvent dissolution, brings inflammable and explosive danger to be also unfavorable for environmental protection and health; General slushing oil is used mineral oil, difficult degradation, and also can bring the problem of oil removing difficulty when antirust for short-term.Therefore, comprehensive study performance is more excellent, and the antirust product being more applicable to for different occasion research is new direction and trend.
Summary of the invention
The object of the present invention is to provide a kind of water-base emulsion type rust protection liquid and preparation method thereof, this rust protection liquid has the feature of long, easy and simple to handle, easy cleaning of antirust time.
Technical scheme of the present invention is as follows:
A water-base emulsion type rust protection liquid, is characterized in that being made by the raw material of following weight part: urethane acrylate 12-15, dodecenylsuccinic acid 4-5, monoethanolamine 1-2, Sodium orthomolybdate 0.9-1.4, polyoxyethylene octylphenol ether 1.5-3, Resorcinol 1-2, two ten four carbon alcohols ester 3-4, EDETATE SODIUM 1-2, auxiliary agent 4-5, water 300.Described auxiliary agent is made by the raw material of following weight part: alkylphenol polyoxyethylene 4-5, nano titanium oxide 0.1-0.2, catechol 1-2, morpholine 2-3, gum arabic 2-3, water glass 1-2, urea 3-4, ammonium persulphate 1-2, water 20-24; Preparation method be ammonium persulphate is water-soluble after, then add other leftover materials, stir 10-15 minute, be heated to 70-80 ℃, stirring reaction 1-2 hour, obtains.
The preparation method of described water-base emulsion type rust protection liquid, is characterized in that comprising the following steps: heat water to 40-50 ℃, add polyoxyethylene octylphenol ether; Continue to be heated to 85-90 ℃, add urethane acrylate, dodecenylsuccinic acid, EDETATE SODIUM, stir 10-15 minute; Add other remaining components, continue to stir 15-20 minute, obtain.
Beneficial effect of the present invention
The present invention has used high score polymer monomer, under the effect of sequestrant, nonionogenic tenside, form stable emulsion, be easy to metallic surface and form film, difficult drop-off, anti-oxidant, be difficult for staiing simultaneously, easy cleaning, objectionable impurities of the present invention is few, and cost is low, and the shot and long term that is applicable to metal products, mechanical component is antirust.
Embodiment
A water-base emulsion type rust protection liquid, by following weight part (kilogram) raw material make: urethane acrylate 13, dodecenylsuccinic acid 4.5, monoethanolamine 1.5, Sodium orthomolybdate 1.2, polyoxyethylene octylphenol ether 2, Resorcinol 1.5, two ten four carbon alcohols esters 3.5, EDETATE SODIUM 1.5, auxiliary agent 4.5, water 300.Described auxiliary agent by following weight part (kilogram) raw material make: alkylphenol polyoxyethylene 5, nano titanium oxide 0.1, catechol 1, morpholine 2, gum arabic 2, water glass 1, urea 3, ammonium persulphate 1, water 20; Preparation method be ammonium persulphate is water-soluble after, then add other leftover materials, stir 10-15 minute, be heated to 70-80 ℃, stirring reaction 1-2 hour, obtains.
The preparation method of described water-base emulsion type rust protection liquid, comprises the following steps: heat water to 46 ℃, add polyoxyethylene octylphenol ether; Continue to be heated to 87 ℃, add urethane acrylate, dodecenylsuccinic acid, EDETATE SODIUM, stir 14 minutes; Add other remaining components, continue to stir 17 minutes, obtain.
The water-base emulsion type rust protection liquid that this embodiment obtains detects by national standard, and humid heat test * (1) is qualified; Salt water immersion test * (1): qualified; Corrosion test * (2): qualified; Rust removability (inferior) < 6.Prepared water-base emulsion type rust protection liquid is brushed on the steel matrix surface of being newly processed into and there is no greasy dirt, be placed in and within indoor 20 days, have no obvious iron mold.
