Abstract

The invention discloses a water-soluble ferrous metal antirust liquid which is prepared from the following raw materials in parts by weight: 4-6 parts of sodium alkane sulfonate, 32-35 parts of amino resin, 2-4 parts of potassium peroxomonosulfate, 2-3 parts of catechol, 3-4 parts of dimethicone, 1-2 parts of nonylphenol polyoxyethylene ether, 1.2-3.5 parts of polydimethylsiloxane, 4-5 parts of 1,6-hexanediol diacrylate, 1-2 parts of EDTA disodium, 4-5 parts of an auxiliary agent, and 300 parts of water. By using the high-molecular polymer resin monomers, the chelating agent and the surface active agent, the antirust liquid has strong affinity to the surface of a metal, is easy to coat, and besides allows a coating film to have stronger protective ability and have antioxidant ability; and the antirust liquid is used in long and short term rust prevention and inter-process rust prevention of ferrous metal products and machinery parts and has excellent performance, has few harmful substances, allows the coating film to be easy to clean up, and has simple process.

Description

A kind of water-soluble black metal rust-inhibiting liquid and preparation method thereof

Technical field

The present invention relates to antirust technology field, relate in particular to a kind of water-soluble black metal rust-inhibiting 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-soluble black metal rust-inhibiting liquid and preparation method thereof, this rust protection liquid has that application is simple, the feature of favorable rust preventing effect, easy cleaning.

Technical scheme of the present invention is as follows:

A kind of water-soluble black metal rust-inhibiting liquid, it is characterized in that being made by the raw material of following weight part: petroleum sodium sulfonate 4-6, aminoresin 32-35, peroxide list potassium sulfonate 2-4, catechol 2-3, dimethyl silicone oil 3-4, polyoxyethylene nonylphenol ether 1-2, polydimethylsiloxane 1.2-3.5,1,6 hexanediyl ester 4-5, EDETATE SODIUM 1-2, auxiliary agent 4-5, water 300.Described auxiliary agent is made by the raw material of following weight part: polyoxyethylene sorbitan monooleate 2-3, nano titanium oxide 0.1-0.2, sodium bicarbonate 1-2, diethanolamine 2-3, carboxymethyl cellulose 2-3, polyvinyl alcohol 1-2, peach gum 1-2, 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-soluble black metal rust-inhibiting liquid, is characterized in that comprising the following steps: by water, dimethyl silicone oil, polyoxyethylene nonylphenol ether, polydimethylsiloxane, petroleum sodium sulfonate, mixing, be heated to 40-50 ℃; Add aminoresin, 1,6 hexanediyl ester, EDETATE SODIUM, continue to be heated to 85-90 ℃, stir 10-15 minute; Add other remaining components, continue to stir 15-20 minute, obtain.

Beneficial effect of the present invention

Rust protection liquid of the present invention, by using macromolecule resin monomer and sequestrant and tensio-active agent, makes rust-preventive agent strong to metallic surface avidity, easily application, and coating protective ability is stronger, films simultaneously and itself has resistance of oxidation; The present invention is antirust for the shot and long term of ferrous metal product, mechanical component, rust prevention during manufacture all has excellent performance, and objectionable impurities is few, films and easily cleans, and operation is simple.
