A technical scheme of the present invention is characterized in that the metal antirust treatment fluid comprises the following raw materials by weight percentage: 15-25% of sodium hydroxide, 4-10% of sodium nitrite, 0.5-1.2% of iron oxide red, 0.1-0.3% of glycerinum, and 65-80% of water.
Description
Technical field
The present invention relates to a kind of metal surface treating liquid, particularly relate to a kind of metal works to machinery industry and enter
The Metal anti-rust treatment liquid of the final antirust treatment of row and application process thereof.
Background technology
For a long time, the surface of workpiece of machinery industry typically after chemical derusting, can be existed by various technology
Surface of workpiece forms layer protecting film, but this layer of protecting film can only to the antirust function of surface of workpiece
Playing temporary transient corrosion inhibition, retention time long the most just can only keeping about 1 year, new corrosion again can be
Gradually form under protecting film and develop.Therefore, research is a kind of can prolonged application be formed anti-at surface of workpiece
The antirust treatment liquid of protective function becomes a theme of current research.
Summary of the invention
It is an object of the invention to the problem short for above-mentioned antirust treatment liquid antirust time, it is provided that a kind of machinery industry
Metal works antirust treatment liquid, after this antirust treatment liquid is grasped by the application process that the present invention provides,
Extend the antirust time length of metal works, favorable rust preventing effect.
The present invention is achieved through the following technical solutions:
Metal anti-rust treatment liquid is formed by the preparation of raw material of following weight percents: sodium hydroxide 15～25%,
Sodium nitrite 4～10%, iron oxide red 0.5～1.2%, glycerol 0.1～0.3%, water 65～80%.
Further improvement of the present invention method is: the purity of described sodium hydroxide is more than 98%, described sodium hydroxide
For chip solid.
Further improvement of the present invention method is: the purity of described sodium nitrite is more than 97%.
Further improvement of the present invention method is: described water distilled water.
The method of applied metal antirust treatment liquid that the present invention provides, including following applying step: by described former
Material and proportioning,
(1) by the raw material mixing post-heating to 150 DEG C of each component ± 5 DEG C, wait to be operated；
(2) metal works after preliminary cleaning is put in the phosphoric acid solution of 3% concentration pickling 2～5 minutes,
Then
Put into the phosphoric acid solution washing surface of the work in clear water reserviors；
(3) metal works after cleaning is placed in special frock, retains certain gap between workpiece and workpiece；
(4) metal works in frock is all submerged in Metal anti-rust treatment liquid, keep antirust treatment liquid in liquid bath
Temperature control at 150 ± 5 DEG C, and rocked special tooling once at interval of 3～4 minutes；Persistently process 10～
After 30 minutes, workpiece is hung antirust treatment liquid, after its surface antirust treatment liquid is dry, hangs treatment trough；
(5) metal works after the antirust treatment of surface be individually placed to two flowing clear water reserviors in repeatedly rinsing until
Process the residue of clean surface of the work completely；
(6) it is completely soaked the workpiece processed with machinery oil, is then placed on special tooling dry.
In the component of technique scheme, the present invention selects sodium hydroxide, sodium nitrite, iron oxide red, glycerol
And water is that raw material is combined so that each raw material effect produces synergism such that it is able to effectively extend metal
The antirust time of work, improves the rust-proof effect of metal.The function of each raw material is respectively as follows:
Sodium hydroxide: existing hydrophilic, has again lipophile, when jointly acting on sodium nitrite and iron oxide red, generates and causes
The complex oxide films such as close Fe3O4 penetrate into metal surface, protect irony article.
Sodium nitrite: in faintly acid, its aqueous solution is more stable, has rust inhibition, belongs to anodic corrosion inhibitor,
Also it is type oxide film corrosion inhibiter, makes metal surface form the very thin even compact oxide-film of passive state, cause metal
Ionizing is obstructed, and suppresses corrosion electrochemistry anode reaction, slows down corrosion of metal.
Iron oxide red: stable in properties, strong covering power, granule is trickle, can play good sealing process in oxide-film.
Heat-resisting, light resistance is good, and the effect to air, bases and diluted acid is highly stable, can strengthen permeability and antirust
Effect.
Glycerol: water absorption is strong, can be used as various metals corrosion inhibiter, high-and low-temperature resistance excellent performance.
Metal works is soaked by the Metal anti-rust treatment liquid of the present invention, the protective oxide layer formed in metal surface, its
Organizational structure is fine and close, granule is trickle, thus improves the ability of the anticorrosive of metal surface and high-and low-temperature resistance.
Its rust-proof effect is: after the metal rust-inhibiting liquid provided by the present invention carries out antirust treatment to metal works, with general
Logical antirust treatment liquid carries out the contrast test after antirust treatment to metal works, at same temperature and humidity bar
Under part, when the flange that common antirust solution processes is put in sample cabinet 6 months, surface produces corrosion phenomena, and same
Time the present invention antirust treatment liquid process flange within 36 months, do not produce corrosion phenomena yet.Described commonly
Antirust treatment liquid is Phosphating Solution, and described Phosphating Solution is made up of the material of following weight ratio: phosphoric acid 2.0-4.0%, oxygen
Change zinc 0.4-0.6%, zinc nitrate 0.5-1.5%, nickel nitrate 3.0-5.0%, manganese nitrate 2.0-4.0%, boron fluoric acid sodium
0.2-1.0%, sodium chlorate 2.0-3.0%, citric acid 0.5-2.0%, soften water, surplus.
Detailed description of the invention
Embodiment is set forth below, and the invention will be further described:
(1) taking by weight percentage: purity is the chip solid sodium hydroxide 20% of 98%, purity is 97%
Sodium nitrite 7%, iron oxide red 1%, glycerol 0.3%, distilled water 72%, put into and liquid pool is mixed to form gold
Belong to antirust treatment liquid and heat
To 150 DEG C, Metal anti-rust treatment liquid pH value is 7.5-10, and pH value is 9 in the present embodiment；
(2) overflow valve after preliminary cleaning is put into pickling 3 minutes in the phosphoric acid solution of 3% concentration, then puts
Enter clear water reserviors wash the phosphoric acid solution of valve surface；
(3) overflow valve after cleaning is placed in special frock, retains certain gap between valve and valve；
(4) overflow valve in frock is all submerged in Metal anti-rust treatment liquid, keep antirust treatment liquid in liquid bath
