A kind of water base cutting cooling antirust liquid and preparation method thereof
Technical field
The present invention relates to antirust technology field, relate in particular to a kind of water base cutting cooling antirust liquid and preparation method thereof.
Background technology
Metal surface is antirust is the important topic in industrial production, and traditional antirust solution, antirust oil has advantage also to have shortcoming. In common aqueous rust preventive, containing a large amount of natrium nitrosums, there is carcinogenicity, be unfavorable for environmental protection and person health, and adopt NMF 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 antirust oil uses 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 cutting cooling antirust liquid and preparation method thereof, this antirust solution has the feature of favorable rust preventing effect, easy and simple to handle, easy cleaning.
Technical scheme of the present invention is as follows:
A kind of water base cutting cooling antirust liquid, is characterized in that being made up of the raw material of following weight portion: methylisobutylketone 9-12,2-methyl isophthalic acid-propyl alcohol 4-6, oleic acid 3-4, triethanolamine 1-2, machine oil 3-4, kerosene 10-12, polyoxyethylene nonylphenol ether 2-3, methenamine 1-2, zinc dialkyl dithiophosphate 0.5-1.2, neopelex 0.9-1.4, acrylic acid dimethylamino ethyl ester 4-5, EDETATE SODIUM 1-2, auxiliary agent 4-5, water 300. Described auxiliary agent is made up of the raw material of following weight portion: APES 4-5, nano titanium oxide 0.1-0.2, catechol 1-2, morpholine 2-3, Arabic gum 2-3, sodium metasilicate 1-2, urea 3-4, ammonium persulfate 1-2, water 20-24; Preparation method be ammonium persulfate is water-soluble after, then add other leftover materials, stir 10-15 minute, be heated to 70-80 DEG C, stirring reaction 1-2 hour, to obtain final product.
The preparation method of described water base cutting cooling antirust liquid, is characterized in that comprising the following steps: heat water to 40-50 DEG C, add polyoxyethylene nonylphenol ether, zinc dialkyl dithiophosphate, 2-methyl isophthalic acid-propyl alcohol, neopelex; Continue to be heated to 85-90 DEG C, add methylisobutylketone, triethanolamine, machine oil, kerosene, acrylic acid dimethylamino ethyl ester, EDETATE SODIUM, stir 10-15 minute; Add other residual components, continue to stir 10-15 minute, to obtain final product.
Beneficial effect of the present invention
The present invention uses organic high molecular polymer monomer and plasticizer, chelating agent acting in conjunction, can form film in metal surface, antirust material by uniform fold in metal surface, isolated air, anti-oxidation, and film easy-clear; Conveniently, production cost is low for good antirust property of the present invention, production and application.
Detailed description of the invention
A kind of water base cutting cooling antirust liquid, by following weight portion (kilogram) raw material make: methylisobutylketone 11,2-methyl isophthalic acid-propyl alcohol 5, oleic acid 3.5, triethanolamine 1.5, machine oil 3.5, kerosene 11, polyoxyethylene nonylphenol ether 2.5, methenamine 1.5, zinc dialkyl dithiophosphate 0.9, neopelex 1.2, acrylic acid dimethylamino ethyl ester 4.5, EDETATE SODIUM 1.5, auxiliary agent 4.5, water 300. Described auxiliary agent by following weight portion (kilogram) raw material make: APES 5, nano titanium oxide 0.1, catechol 1, morpholine 2, Arabic gum 2, sodium metasilicate 1, urea 3, ammonium persulfate 1, water 20; Preparation method be ammonium persulfate is water-soluble after, then add other leftover materials, stir 10-15 minute, be heated to 70-80 DEG C, stirring reaction 1-2 hour, to obtain final product.
The preparation method of described water base cutting cooling antirust liquid, comprises the following steps: heat water to 45 DEG C, add polyoxyethylene nonylphenol ether, zinc dialkyl dithiophosphate, 2-methyl isophthalic acid-propyl alcohol, neopelex; Continue to be heated to 88 DEG C, add methylisobutylketone, triethanolamine, machine oil, kerosene, acrylic acid dimethylamino ethyl ester, EDETATE SODIUM, stir 13 minutes; Add other residual components, continue to stir 13 minutes, to obtain final product.
The water base cutting cooling antirust liquid that this embodiment obtains detects by national standard, and damp heat test * (1) is qualified; Salt water immersion test * (1): qualified; Corrosion test * (2): qualified; Rust removability (inferior) < 6. Prepared water base cutting cooling antirust 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.
