The cumbersome operation process of conventional derusting rust-proofing is become, has only needed simply to brush, spray or soak at normal temperatures, you can synchronously complete
Degreasing derusting rust-proofing.
Chinese patent CN1418920 discloses a kind of metal rust removing and resisting paint and its production method, the formula of the antirust paint
For:H3PO4 36-41%;Acetic acid 8-10%;FePO4 9-13%;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, several times to 5 ∽, 7 parts of reduced iron powders are added in solution, 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, stirred evenly, static 24 hours
It is stand-by afterwards.The patent has the disadvantage that：The ferric phosphate and manganese carbonate contained in formula composition, 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 antirust solution, and it has very strong oozing
Saturating ability, can effectively disintegrate rapidly greasy dirt common on metal surface, and one layer is converted it into while corrosion is decomposed
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 antirust solution.
To achieve the above object, the technical solution adopted by the present invention is as follows：
A kind of antirust solution, in terms of 1 liter, each raw material components and its content are in the solution：
Fluorine zirconic acid 370-410 g/L, sodium dihydrogen phosphate 80-100 g/L, ferric nitrate 90-130 g/L, glycerine 1-5 g/L, nitre
Sour manganese 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 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 antirust solution of the present invention in turn includes the following steps：
(1) fluorine zirconic acid is stirred evenly in kettle with water to miscible；
(2) and then to sodium dihydrogen phosphate is added in it, stir evenly, stand 1-2 hours;
(3) several times slowly to adding reduced iron powder in solution 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 glycerine, ferric nitrate and manganese nitrate, adds octyl phenol and gathers
Oxygen vinethene and disodium ethylene diamine tetraacetate, stir evenly, stand-by after standing 20-24 hours.Wherein Octylphenol polyoxyethylene ether and ferric nitrate
Rust cleaning and film forming speed can be accelerated, disodium ethylene diamine tetraacetate plays complexing, it is ensured that the stability of system.Glycerine is bleeding agent,
Its addition can be such that rust remover is rapidly introduced into inside rusty scale, and the addition of manganese nitrate can improve the resistance to corrosion of the antirust coat of formation.
Main operational principle of the invention is as follows：
Excessive fluorine zirconic acid can playing rust act on, phosphoric acid salt plays film forming corrosion protection, and inorganic manganese salt plays electrochemistry
Protective effect.
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 the enough fluozirconate of generation
Class, plays film forming protective effect.
Iron rust can be transformed into this product the compound of stabilization, and the main component of iron rust is ferrous hydroxide, and its reaction equation is：
Fe(OH)2+H2ZrF6→FeZrF6+H2O
FeZrF6 is securely joined with, in steel surface, forming fine and close protectiveness overcoat, and the formation of fluorine zirconic acid manganese salt improves
The resistance to corrosion of overcoat, so as to reach corrosion protection purpose.
Antirust solution 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 are:Because unique formula is designed, antirust solution has very strong penetrating power, energy
Effectively disintegrating greasy dirt common on metal surface rapidly, and one layer is converted it into while corrosion is decomposed has corrosion protection
The metal protective film of energy, so as to reach excellent rust cleaning and rust-proof effect.
Effect after antirust solution use of the present invention is as follows：
1st, full-featured, effect is unique.The multiple performances such as this product collection " oil removing, decontamination, rust cleaning, phosphatization, passivation, antirust " are in one
