Abstract
The invention discloses a rust removing and preventing liquid for steel. The rust removing and preventing liquid is prepared from the following raw materials in parts by weight: 1-2 parts of diallylamine, 2-3 parts of rosin-polythylene oxide ester, 1-2 parts of phosphoric acid, 1-2 parts of magnesium chloride, 2-3 parts of thiourea, 1-2 parts of sodium dodecyl sulfate, 6-9 parts of diethylene glycol dibenzoate, 1.5-2.5 parts of peregal, 1-2 parts of EDTA (ethylene diamine tetraacetic acid) disodium, 4-5 parts of additives, and 300 parts of water. The rust removing and preventing liquid for steel disclosed by the invention is rapid in rust removal; due to an adopted high-molecular polymer and a chelating agent, a layer of thin film is formed on the metal surface so as to achieve air-isolating and anti-oxidation effects, and the thin film is easily removed just by virtue of water washing. The rust removing and preventing liquid for steel disclosed by the invention is low in manufacturing process cost, and suitable for being used under the low temperature condition of 12-35 DEG C, and the film can be rapidly formed in 0.5-3 minutes, so that the rust prevention performance of the rust removing and preventing liquid for steel is good, and superior to GB6807 standards; the rust removing and preventing liquid for steel disclosed by the invention is small in environmental pollution, and beneficial to popularization and utilization.
Description
Technical field
The present invention relates to antirust technology field, relate in particular to a kind of steel derusting 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 steel derusting rust protection liquid and preparation method thereof, this rust protection liquid has long feature of fast, antirust time of film forming.
Technical scheme of the present invention is as follows:
A steel derusting rust protection liquid, is characterized in that being made by the raw material of following weight part: diallyl amine 1-2, sylvic acid polyoxyethylene ester 2-3, phosphatase 11-2, magnesium chloride 1-2, thiocarbamide 2-3, sodium laurylsulfonate 1-2, Diethylene Glycol Dibenzoate 6-9, peregal 1.5-2.5, 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 steel derusting rust protection liquid, is characterized in that comprising the following steps: heat water to 40-50 ℃, add sylvic acid polyoxyethylene ester, peregal, sodium laurylsulfonate; Continue to be heated to 85-90 ℃, add Diethylene Glycol Dibenzoate, diallyl amine, stir 10-15 minute; Add other remaining components, continue to stir 15-20 minute, obtain.
Beneficial effect of the present invention
The present invention eliminates rust soon, and uses high molecular polymer and sequestrant, can form thin film in metallic surface, and isolated air is anti-oxidation, film easy-clear, and washing is fallen; Manufacturing process cost of the present invention is low, is suitable for 12 ℃ of-35 ℃ of cold condition and uses, can be in 0.5-3 minute fast filming, good antirust property, is better than GB6807 standard; Environmental pollution of the present invention is little, is beneficial to and promotes the use of.
