Abstract

The invention discloses an antirust fluid for an inner cavity of a metal part. The anti-rust fluid is prepared from the following raw materials in parts by weight: 3-4 parts of critic acid, 2-3 parts of triethanolamine, 2-3 parts of petroleum sodium sulfonate, 1-2 parts of fatty alcohol-polyoxyethylene ether, 1-2 parts of sodium molybdate, 30-34 parts of ethanol, 2-3 parts of etidronic acid, 3-4 parts of 2-butoxy-ethanol, 1-2 parts of isopropanol, 10-12 parts of ethoxylated trimethylolpropane triacrylate, 1-2 parts of ethylene diamine tetraacetic acid (EDTA) disodium, 4-5 parts of assistant and 300 parts of water. A film can be formed on the metal surface by using polymer resin and a chelating agent, so as to play air-isolation and anti-oxidation roles; meanwhile, an antirust agent can be firmly adhered, so that the anti-rust effect is long; the ingredients such as volatile acid, heavy metal ions, sodium nitrite and the like do not exist, so that the antirust fluid is free of residual rust slag, free of pollution, low in cost and good in economic benefits, and can be applied to rust control of inner cavity parts of a car of cast iron and steel materials in batches; the anti-rust requirements of the cast iron or steel parts of the car are met.

Description

A kind of metal parts antirust liquid for inner chamber and preparation method thereof

Technical field

The present invention relates to antirust technology field, relate in particular to a kind of metal parts antirust liquid for inner chamber 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 metal parts antirust liquid for inner chamber and preparation method thereof, this rust protection liquid has that the antirust time is long, non-volatility is sour, without the residual feature of anvil cinder.

Technical scheme of the present invention is as follows:

A metal parts antirust liquid for inner chamber, is characterized in that being made by the raw material of following weight part: citric acid 3-4, trolamine 2-3, petroleum sodium sulfonate 2-3, fatty alcohol-polyoxyethylene ether 1-2, Sodium orthomolybdate 1-2, ethanol 30-34,1-Hydroxy Ethylidene-1,1-Diphosphonic Acid 2-3,2-butoxy-ethanol 3-4, Virahol 1-2, ethoxylated trimethylolpropane triacrylate 10-12, 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, tripoly phosphate sodium STPP 1-2, water glass 1-2, urotropine 1-2, Resorcinol 1-2, borax 3-4, urea 2-3, ammonium persulphate 1-2, peach gum 2-3, 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 metal parts antirust liquid for inner chamber, is characterized in that comprising the following steps: water, petroleum sodium sulfonate, fatty alcohol-polyoxyethylene ether are mixed, be heated to 40-50 ℃; Add ethanol, 2-butoxy-ethanol, Virahol, ethoxylated trimethylolpropane triacrylate, 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

The present invention uses macromolecule resin, sequestrant, can form film in metallic surface, plays isolated air, and anti-oxidation effect can be sticked rust-preventive agent more securely, and rust-proof effect is permanent; There is no the compositions such as volatile acid, heavy metal ion and Sodium Nitrite, residual without anvil cinder, pollution-free, met the antirust requirement of automobile cast iron or steel-iron components, automobile inner cavity part antirust that can large batch ofly be applied to cast iron and steel matter, cost is lower, good in economic efficiency.
