Chinese patent CN1418920 discloses a kind of metal rust removing and resisting paint and its production method, the formula of the antirust paint For:H3PO436-41%;Acetic acid 8-10%;FePO49-13%;Glycerine 0.1-0.5%;Manganese carbonate 0.1-0.2%;Balance of water. The production method of the antirust paint is:It is I, the water of the phosphoric acid of 50 parts of 38 ∽, 42 parts of 38 ∽ is miscible in reactor, then, Xiang Qi Interior addition 8 ∽, 10 parts of acetic acid.II, after static 0.5 hour, add 5 ∽, 7 parts of reduced iron powders into solution several times, stir evenly.III、 After reacting 12 hours, 0.2 part of manganese carbonate of 0.1 ∽, 0.4 part of glycerine and 0.1 ∽ is added thereto to, is stirred evenly, static 24 hours It is stand-by afterwards.The patent has the disadvantage that：The ferric phosphate contained in the formula composition and manganese carbonate, have not readily dissolved in feed liquid Entirely, particularly ferric phosphate, easily forms precipitation.
The content of the invention
An object of the present invention is to overcome the deficiencies in the prior art, there is provided a kind of derusting rust-proofing liquid, and it has very strong Penetrating power, greasy dirt common on metal surface can be effectively disintegrated rapidly, and convert it into while corrosion is decomposed One layer of metal protective film with anti-corrosion performance, so as to reach excellent rust cleaning and rust-proof effect.
The second object of the present invention is the preparation method for providing above-mentioned derusting rust-proofing liquid.
For achieving the above object, the technical solution used in the present invention is as follows：
A kind of derusting rust-proofing liquid, in terms of 1 liter, each raw material components and its content are in the solution：
Fluorine zirconic acid 360-410 g/L, sodium dihydrogen phosphate 80-100 g/L, ferric nitrate 90-130 g/L, ethylene glycol 1-5 g/ L, manganese nitrate 1-3 g/L, Octylphenol polyoxyethylene ether 3-5 g/L, disodium ethylene diamine tetraacetate 5-10 g/L, balance of water.
The preferred 370-400 g/L of consumption of wherein described fluorine zirconic acid；
The preferred 90-100 g/L of consumption of wherein described sodium dihydrogen phosphate；
The preferred 100-120 g/L of consumption of wherein described ferric nitrate；
The preferred 2-4 g/L of consumption of wherein described ethylene glycol；
The preferred 1.5-3 g/L of consumption of wherein described manganese nitrate；
The preferred 4-5 g/L of consumption of wherein described Octylphenol polyoxyethylene ether；
The preferred 7-9 g/L of consumption of wherein described disodium ethylene diamine tetraacetate.
The preparation method of derusting rust-proofing liquid of the present invention in turn includes the following steps：
(1) fluorine zirconic acid and water are stirred evenly to miscible in kettle；
(2) sodium dihydrogen phosphate and then into it is added, is stirred evenly, stand 1-2 hours;
(3) slowly into solution reduced iron powder is added several times in stirring（5-9g/L) stir evenly, stand 10-12 hours;
(4) contamination precipitation in iron powder to be restored goes down, and is added thereto to ethylene glycol, ferric nitrate and manganese nitrate, adds Octylphenol polyoxyethylene ether and disodium ethylene diamine tetraacetate, stir evenly, and stand stand-by after 20-24 hours.Wherein octyl phenol gathers Oxygen vinethene can accelerate rust cleaning and film forming speed with ferric nitrate, and disodium ethylene diamine tetraacetate plays complexing, it is ensured that system Stability.Ethylene glycol is bleeding agent, and its addition can be such that rust remover is rapidly introduced into inside rusty scale, and the addition of manganese nitrate can be improved The resistance to corrosion of the antirust coat of formation.
The main operational principle of the present invention is as follows：
Excessive fluorine zirconic acid can the effect of playing rust, phosphoric acid salt plays film forming corrosion protection and acts on, and inorganic manganese salt plays electricity Chemoproection is acted on.
The main component of reduced iron powder is di-iron trioxide, and it is reacted with fluorine zirconic acid in solution, and reaction equation is as follows：
Fe2O3+H2ZrF6→Fe2（ZrF6）3+H2O
Adding the purpose of reduced iron powder is, in the case of the iron rust amount deficiency of metal surface, remains to generate enough fluorine zirconiums Barbiturates, plays film forming protective effect.
Iron rust can be transformed into stable compound by this product, and the main component of iron rust is ferrous hydroxide, and its reaction equation is：
Fe(OH)2+H2ZrF6→FeZrF6+H2O
FeZrF6It is securely joined with, in steel surface, forming fine and close protectiveness overcoat, the formation of fluorine zirconic acid manganese salt is carried The high resistance to corrosion of overcoat, so as to reach corrosion protection purpose.
Derusting rust-proofing liquid of the present invention can be used directly under normal temperature normality to spray workpiece, brushed or soaked.
The beneficial effects of the present invention is:Because unique formula is designed, derusting rust-proofing liquid has very strong osmotic energy Power, can effectively disintegrate rapidly greasy dirt common on metal surface, and one layer is converted it into while corrosion is decomposed and have The metal protective film of anti-corrosion performance, so as to reach excellent rust cleaning and rust-proof effect.
Derusting rust-proofing liquid of the present invention is as follows using rear effect：
1st, complete function, effect are unique.The multiple performances such as this product collection " oil removing, decontamination, rust cleaning, phosphatization, passivation, antirust " in Integrally, using unique decomposition and inversion composition principle, complete the step of degreasing derusting rust-proofing one, the slaine diaphragm that it is formed is attached Put forth effort as I grade, be well combined with various paint, meet the requirements of coating standard.
2nd, nontoxic, Environmental Safety.The toxic acids of deep-etching such as this product is not hydrochloric, sulfuric acid, hydrofluoric acid, and adopt Fluorine zirconic acid so as to keep the acid number of safety and stability.
