Abstract

The present invention discloses a kind of method for removing steel surface rusty stain, and it is put into soak I including pending steel, and is soaked under specific Ultrasonic Conditions；The soak I is made up of following raw material：Neopelex, ethyoxyl lauryl alcohol, NONYL PHENOL ETHOXYLATED ether, hydroxyacetic acid, sodium tripolyphosphate, carboxyl acetic acid and water；Steel is taken out, cooled down, and is immersed in soak II, and is soaked under the conditions of special ultrasonic ripple；The soak II is made up of following raw material：Vinyl triamine, ethylene glycol, modified silicone resin, acrylic acid ester emulsion, phosphoric acid, zinc oxide, sodium dichromate, nitric acid and water.It is of the invention that ultrasound is first carried out according to the specific ultrasonic power of components utilising and frequency of soak I, recycle the principle expanded with heat and contract with cold, and handled according to the specific ultrasonic power of components utilising and frequency of soak II, so as to not only remove the purpose of rusty stain, it can also effectively prevent steel surface and occur the phenomenon got rusty again.

Description

The method for removing steel surface rusty stain
Technical field
The present invention relates to metal Surface Treatment Technique field, more particularly to a kind of method for removing steel surface rusty stain.
Background technology
It is a kind of chemical reaction to get rusty, and is substantially the oxidation reaction of metal.Most common phenomenon of getting rusty is ironwork length Phase is exposed in air and oxygen is there occurs oxidation reaction, or turns into oxide by the oxygen element erosion in water.Iron rust is A kind of material of brownish red, it is so hard unlike iron, it is easy to comes off, after one block of iron gets rusty completely, volume can swell 8 times. If iron rust does not remove, this spongiform iron rust is particularly easy to absorb moisture, and iron also just gets rusty faster.
However, the minimizing technology on steel surface rusty stain has much at present, but removal effect is bad, by place of derusting Easily there is the phenomenon got rusty again in steel after reason.
The content of the invention
The present invention provides a kind of method for removing steel surface rusty stain, and this method can solve existing removal steel surface rust The method removal effect of mark is bad, and the phenomenon got rusty easily occurs again in the steel after processing of derusting.
In order to solve the above-mentioned technical problem, the technical solution adopted in the present invention is：
It comprises the following steps：
A. pending steel is put into soak I, and ultrasonic power be 20W~30W, supersonic frequency be 30KHz~40KHz Ultrasonic Conditions under carry out, be completely soaked 30min~60min；
Wherein, the soak I is to be prepared from the following raw materials in parts by weight：4 parts~6 parts of neopelex, ethoxy 1 part~3 parts of base lauryl alcohol, 1 part~5 parts of NONYL PHENOL ETHOXYLATED ether, 5 parts~10 parts of hydroxyacetic acid, sodium tripolyphosphate 5 parts~8 50 parts~75 parts of part, 15 parts~20 parts of carboxyl acetic acid and water；
B. the steel Jing Guo step A immersion treatment is taken out, dries its surface moisture, be then first cooled to 5 DEG C~10 DEG C, then Be fully immersed in 50 DEG C~60 DEG C of soak II, and ultrasonic power be 80W~95W, supersonic frequency be 65KHz~ The min of 10min~15 is handled under 75KHz Ultrasonic Conditions；
Wherein, the soak II is to be prepared from the following raw materials in parts by weight：1 part~5 parts of vinyl triamine, 8 parts of ethylene glycol ~10 parts, 15 parts~25 parts of modified silicone resin, 15 parts~25 parts of acrylic acid ester emulsion, 5 parts~10 parts of phosphoric acid, 5 parts of zinc oxide~ 100 parts~150 parts of 10 parts, 5 parts~8 parts of sodium dichromate, 15 parts~20 parts of nitric acid and water.
Due to using above-mentioned technical proposal, the beneficial effect that the present invention obtains is：
It is of the invention that ultrasound is first carried out according to the specific ultrasonic power of components utilising and frequency of soak I, so as to promote to soak Liquid I is sufficiently infiltrated through in the top layer rusty stain of steel, reaches the purpose for removing rusty stain；Meanwhile recycle the original expanded with heat and contract with cold Reason, and handled according to the specific ultrasonic power of components utilising and frequency of soak II, so as to further phosphating solution Sufficiently infiltrate through the top layer of steel and carry out phosphating reaction, reach effectively prevention steel surface showing of occurring getting rusty again As.
