Abstract
The invention discloses a kind of Water-emulsion-type antirust liquid, it is made up of the raw material of following weight portion: ammonium nitrate 1-2, sodium benzoate 1-2, m-xylene diamine 1-2,3-methyl-1-butanol 4-5, methyl trichlorosilane 3-5, isopropyl acetate 20-22, sodium laurate 1-2, dimethylaminoethyl methacrylate 10-12,1,6 hexanediyl ester 10-12, EDETATE SODIUM 1-2, auxiliary agent 4-5, water 300.Present invention uses macromolecule resin and chelating agen, can form thin film in metal surface, play isolation air, anti-oxidation effect, and antirust agent difficult drop-off, thin film itself has antioxidative effect, improves corrosion mitigating effect, and thin film easily removes；The present invention is little to metal surface tension, it is easy to application, has the feature of osmosis type, transformant and three kinds of antirusting paints of stable type simultaneously, produces extremely simple.
Description
Technical field
The present invention relates to technical field of rust prevention, particularly relate to a kind of Water-emulsion-type antirust liquid and preparation method thereof.
Background technology
Metal surface is antirust is the important topic in commercial production, and traditional antirust solution, antirust oil have advantage also to have shortcoming.Containing substantial amounts of sodium nitrite in common aqueous rust preventive, there is carcinogenecity, be unfavorable for that environmental protection and the person are healthy, and adopt wetting agent to extend the life-span of aqueous rust preventive, bring again the disadvantage touched with one's hand, be covered with dust, and can not long-term rust prevention；Although general hard film rust preventive oil is suitable for long-term rust prevention, film forming is also transparent attractive in appearance, but water white resin types is less, and instability is easy oxidation discoloration also, in addition it is also necessary to 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 brings along the problem that oil removing is difficult during for short-term rust prevention.Therefore, comprehensive study performance is more excellent, and the antirust product being more suitable for for different occasion researchs is new direction and trend.
Summary of the invention
It is an object of the invention to provide a kind of Water-emulsion-type antirust liquid and preparation method thereof, this antirust solution has antirust time length, feature easy and simple to handle.
Technical scheme is as follows:
A kind of Water-emulsion-type antirust liquid, it is characterized in that being made up of the raw material of following weight portion: ammonium nitrate 1-2, sodium benzoate 1-2, m-xylene diamine 1-2,3-methyl-1-butanol 4-5, methyl trichlorosilane 3-5, isopropyl acetate 20-22, sodium laurate 1-2, dimethylaminoethyl methacrylate 10-12,1,6 hexanediyl ester 10-12, EDETATE SODIUM 1-2, auxiliary agent 4-5, water 300.Described auxiliary agent is made up of the raw material of following weight portion: polyoxyethylene sorbitan monooleate 2-3, nano titanium oxide 0.1-0.2, catechin 1-2, ethanol 10-12, sodium silicate 3-4, resorcinol 1-2, propylene glycol 3-4, morpholine 1-2, Resina persicae 2-3, Ammonium persulfate. 1-2, water 20-24；Preparation method is after dissolving ammonium persulfate into water, adds other leftover materials, stirs 10-15 minute, heats to 70-80 DEG C, stirring reaction 1-2 hour, to obtain final product.
The preparation method of described Water-emulsion-type antirust liquid, it is characterised in that comprise the following steps: by water, sodium laurate mixing, heating is to 40-50 DEG C；Add 3-methyl-1-butanol, isopropyl acetate, dimethylaminoethyl methacrylate, 1,6 hexanediyl ester, EDETATE SODIUM, continue to be heated to 85-90 DEG C, stir 10-15 minute；Add other residual componentss, continue stirring 15-20 minute, to obtain final product.
Beneficial effects of the present invention
Present invention uses macromolecule resin and chelating agen, can form thin film in metal surface, play isolation air, anti-oxidation effect, and antirust agent difficult drop-off, thin film itself has antioxidative effect, improves corrosion mitigating effect, and thin film easily removes；The present invention is little to metal surface tension, it is easy to application, has the feature of osmosis type, transformant and three kinds of antirusting paints of stable type simultaneously, produces extremely simple.
