Abstract
The invention discloses a cast iron derusting antirust liquid which is prepared from the following raw materials in parts by weight: 6-8 parts of dicyclohexylamine, methanol, 2-4 parts of trisodium phosphate, 5-8 parts of sodium nitrite, 3-6 parts of zinc oxide, 3-4 parts of polyoxyethylene alkyl ether, 1-2 parts of polysorbate, 3-6 parts of cellulose acetate, 20-25 parts of phenolic resin, 1-2 parts of hydrolyzed polymaleic anhydride, 6-10 parts of fluorocarbon resin, 1-2 parts of EDTA disodium, 4-5 parts of an auxiliary agent, and 300 parts of water. With use of various organic high-molecular polymer monomers and the chelating agent, an antirust film can be formed on a metal surface, isolates air, adheres an antirust agent, prevents oxidation, is easy to clean up, and can be immediately removed by water washing; and the antirust liquid does not easily stick dust, allows the cast iron surface to be quite clean, has small pollution on the environment, and has simple operation, no damage to an operator, long antirust time and high safety.
Description
Technical field
The present invention relates to antirust technology field, relate in particular to a kind of cast iron rust-removing and antirusting agent 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 cast iron rust-removing and antirusting agent and preparation method thereof, this rust protection liquid have the antirust time grow, be not covered with dust, the feature of easy-clear.
Technical scheme of the present invention is as follows:
A cast iron rust-removing and antirusting agent, is characterized in that being made by the raw material of following weight part: dicyclohexyl amine 6-8, methyl alcohol, tertiary sodium phosphate 2-4, Sodium Nitrite 5-8, zinc oxide 3-6, Voranol EP 2001 3-4, polysorbate 1-2, cellulose acetate 3-6, resol 20-25, hydrolytic polymaleic anhydride 1-2, fluorocarbon resin 6-10, 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 cast iron rust-removing and antirusting agent, is characterized in that comprising the following steps: water, Voranol EP 2001, polysorbate are mixed, be heated to 40-50 ℃; Add cellulose acetate, resol, hydrolytic polymaleic anhydride, fluorocarbon resin, EDETATE SODIUM, continue to be heated to 80-90 ℃, stir 15-20 minute; Add other remaining components, continue to stir 15-20 minute, obtain.
Beneficial effect of the present invention
The present invention uses multiple organic high molecular polymer monomer and sequestrant, can form anti-rust film in metallic surface, and isolated air, sticks rust-preventive agent, anti-oxidation, and film easy-clear, and washing is fallen; Rust protection liquid of the present invention is difficult for sticky dust, and Cast Iron Surface is very clean, and environmental pollution is less, easy and simple to handle, and to operator, without injury, the antirust time is long, safe.
