Description
Technical field
The invention belongs to cleaning agent field, and in particular to a kind of preparation method of rust remover.
Background technology
Traditional rust remover can chemically react usually using strong acid, acid with iron rust and metal oxide, and generation is solvable
Property salt, so as to reach the purpose of derusting.With the development of recirculated cooling water technology and more and more extensive, the gold of reverse osmosis applications
The corrosion problem of category steel etc. becomes increasingly conspicuous, and the metal material and the weight of equipment that the whole world is scrapped due to corrosion every year are about
More than 20 parts of metal annual production, derusting is primary processing step before taking metallic article various anti-corrosion measures.Metal is put
Got rusty easily under outdoor or open-air condition, not only influence presentation quality, the technique such as can also influence to paint, be bonded it is normal enter
OK, these iron rust have a strong impact on the operation of subsequent technique and the quality of product, such as handle not in time, can more cause the report of material
It is useless, cause unnecessary economic loss.Therefore, derusting is the necessary process of pre-treatment link in Surface Treatment Engineering, Ye Shibiao
First of critical point of face processing.From technique, derusting does not directly influence the operation of next process thoroughly, and may be dirty
Contaminate subsequent production line；For coating quality, derusting can thoroughly not reduce the adhesive force of film, also affect the other of coating
Performance.Through being commonly encountered in industrial production, for example, room temperature blackening film layer is uneven, color is inconsistent, it is local blacks not on, it is chemical
It is bad to plate plating leakage, adhesion, does not all have direct relation thoroughly with pre-treatment derusting the problems such as pin hole.It can be said that under normal circumstances,
50 ~ 70% surface treatment quality problem be due to derusting thoroughly caused by, so workpiece surface rust stain must clean up.
The purpose of derusting be in order to ensure, recover metal material and the original performance of product and function, or ensure that metal material is follow-up
Process unaffected, for example metal substrate is distinctly claimed before application and is not allow for corrosion.Currently, the method for derusting mainly includes thing
Reason method and the class of chemical method two.Wherein, the method for chemical derusting is mainly immersion type pickling, and small part is using brush in addition
The modes such as painting, erasing.Existing derusting agent prescription and technique effect are not obtaining breakthrough in recent years, therefore it provides a kind of
Metal surface corrosion can be effectively removed, the rust remover for substantially reducing the metal scrappage caused by corrosion is very urgent.It is existing
The species of rust remover is a lot, is divided into acid and neutrality from pH value, acidic deruster is by one or more strong acid and additive system
Into acidic derusting technique abbreviation pickling；Neutral rust remover is made up of one or more chelating agents and additive, but chelatropic reaction phase
To weaker, although these rust removers have certain effect, but as that, as rust remover, can cause acid occur using concentrated hydrochloric acid
Mist, while the problem of Hydrogen Brittleness Phenomena can occur in descaling process, thus produce a kind of rust remover of high-efficiency environment friendly there is
The very big market demand.
The content of the invention
The technical problems to be solved by the invention：For at present to pursue rust cleaning efficiency, being used as and being removed using concentrated hydrochloric acid
Become rusty agent, the problem of causing acid mist occur, while Hydrogen Brittleness Phenomena can occur in descaling process, there is provided a kind of preparation side of rust remover
Method.
In order to solve the above technical problems, the present invention is using technical scheme as described below：
A kind of preparation method of rust remover, the preparation method comprise the following steps：
