Description
Technical field
The present invention relates to a kind of antirust agent, belongs to organic compound technical field, more particularly to a kind of antirust agent and its
Preparation method rolls acid with it antirust application of chill coil of strip of middle database.
Background technology
Domestic sour rolling mill annual output crosses million tons, and the advanced turbulence acid dip technique of sour rolling mill generally use is sour
Liquid is sprayed from the spray beam for being located at each acid tank both ends to strip, acid solution is formed strong turbulent condition in groove, can be improved
Pickling efficiency, shorten pickling time, so as to improve pickling speed.
Hydrochloric acid takes off that hot rolled plate oxide skin ability is strong, and iron salt dissolved speed is big, and powder precipitate is few in hydrochloric acid pickler,
Pickling rear surface is in good condition, and it is small to ooze hydrogen influence.During hot rolled plate hydrochloric acid pickling, it can be seen that surface of steel plate has substantial amounts of gas
Bubble is emerged, while has scale spallation, and substantial amounts of bubble is the hydrogen that acid corrosion iron-based is released, and bubble speed of emerging is faster, acid
It is also more serious to corrode iron-based.Hydrochloric acid high volatility, can produce substantial amounts of acid mist in use, and an acid mist part is iron in corruption
Hydrogen is generated during erosion with effusion, another part is that acid solution heat is volatilized and produced.Acid mist seriously pollutes production operation ring
Border, it is also very serious to workshop and equipment corrosion, serious harm is also brought at the same time to health of human body.Therefore, in chlorohydric acid pickling mistake
How Cheng Zhong, prevent acid mist from becoming focus of concern.
The planisher for being usually provided at acid tank outlet is used for improving strip profile and flatness and surface quality, required by obtaining surface
Roughness, has the function that to improve strip mechanical performance, while also higher to the surface quality requirements of pickling chill plate.
Acid rolls the side that middle database is usually just arranged on sour rolling mill, and particularly summer temp is high, humidity is big, acid mist is big,
The chill coil of strip of middle database is stored 2 days or so, and yellow rust occurs in its outer ring, inner ring, edge, and after storing 10 days, coil of strip occurs
Serious yellow rust.Therefore, the acid stored there is an urgent need to reservoir area rolls chill coil of strip and deposits phase extension, and initial time of getting rusty is delayed, corrosion ratio
Reduce.
If carrying out antirust treatment to chill coil of strip, above-mentioned purpose can be reached.
Existing antirust agent is divided into oiliness antirust agent and water-based antirust agent, environmentally-friewater-borne water-borne antirusting agent have it is fire retardant, less toxic,
The features such as environmentally friendly, be environmentally friendly product, brush and continuous, fine and close protective layer is formed in steel surface, is completely cut off in air
Oxygen and water are contacted with steel surface, achieve the purpose that antirust.The protective film of formation is very thin and very fine and close, can keep steel base
Body colour, antirust is easy to operate, and the modes such as immersion, spraying, brushing can be used to handle.
The content of the invention
In order to solve the above technical problems, middle database is rolled to acid with it the invention discloses a kind of antirust agent and preparation method thereof
The antirust application of chill coil of strip.
To achieve the above object, the invention discloses a kind of antirust agent, by percentage to the quality, it is by following component group
Into：Main corrosion inhibiter：40~60%, corrosion inhibitor：10~15%, surplus is deionized water；The main corrosion inhibiter is by following matter
Measure the component composition of degree：Phytic acid：30~50%, tannic acid：30~50%, hexamethylenetetramine：10~20%, three
Monoethanolamine：10~20%.
It is further preferred that the main corrosion inhibiter is made of the component of following mass percentage content：Phytic acid：30~
40%, tannic acid：30~40%, hexamethylenetetramine：15~20%, triethanolamine：15~20%.
Further, the corrosion inhibitor is made of the component of following mass percentage content：Urea：50~
80%, methenamine：20~50%.
Preferred as technical scheme, the main corrosion inhibiter is made of the component of following mass percentage content：
Phytic acid：30%, tannic acid：40%, hexamethylenetetramine：20%, triethanolamine：10%.The corrosion inhibitor is by following matter
Measure the component composition of degree：Urea：60%, methenamine：40%.
The invention also discloses the method for preparing above-mentioned antirust agent, it includes the following steps：
1) phytic acid that mass percentage content is 30~50%, 30~50% tannic acid, 10~20% six first are taken
Urotropine and 10~20% triethanolamine are added in deionized water after mixing, and configuration obtains main corrosion inhibiter liquid；
2) urea that mass percentage content is 50~80% is taken to be added sequentially to 40~50 DEG C with 20~50%
In ionized water, it is evenly stirred until that being completely dissolved configuration obtains corrosion inhibitor liquid；
3) take the main corrosion inhibiter liquid of the step 1) to be uniformly mixed with the corrosion inhibitor liquid of the step 2), add surplus
Remaining deionized water, that is, be prepared antirust agent.
Preferably, the deionized water in the step 1) and the deionized water in step 2) and main corrosion inhibiter, auxiliary inhibition
Agent forms absolutely content.
In order to preferably realize technical scheme, in being rolled using above-mentioned antirust agent for acid
Between the chill coil of strip in storehouse antirust.
Specific antirust treatment process is that the chill coil of strip that acid is rolled to middle database is impregnated in by the main corrosion inhibiter, auxiliary
In the solution of corrosion inhibiter and deionized water composition, 3~10min is handled, is then taken out in the sour milling train working environment for being placed in simulation,
Calculate coil of strip surface and the time of corrosion occur.
Further, there is the time ＞ 10min of corrosion in the chill coil of strip surface after the antirust agent solution treatment.
The selection principle of each component in the antirust agent of the present invention：
Phytic acid：Be otherwise known as phytic acid, is the organic phosphoric acid compound extracted from cereal crops, same containing energy
24 oxygen atoms of metal combination, are a kind of multiple tooth chelating agents of very strong metal, when with metal complex, are easily formed and contain multiple chelas
The fine and close unimolecule organic protective film of cyclization, the unimolecule organic protective film all have extremely strong stabilization in extensive pH value range
Property, it can effectively stop O2Deng metal surface is entered, so as to suppress corrosion of metal, the metal surface after processing is due to formation
With hydroxyl and phosphate isoreactivity group chemical action occurs for organic monolayers layer, has stronger cementitiousness, in addition, phytic acid
Self assembly and sustained release performance in steel surface, can also improve corrosion resistance.
