Description
Technical field
The present invention relates to cleaning metal surface field, in particular to a kind of preparation side of neutral metal surface derusting cleaning agent
Method and its application.
Background technique
In use, many metal materials can cause surface corrosion feelings occur to metal with the extension of use time
Condition, and once corrode, then weathering phenomenon easily occurs, metal material service performance is caused to substantially reduce, and corrode
There are the surface layers of metal for metal, and often leading to entire metal cannot use.Getting rusty is a kind of chemical reaction, long when the time that iron is put
It will get rusty.When the oxygen in air is dissolved in water, oxygen reacts in the environment for having water with iron, can generate iron oxide
Thing, here it is iron rust, iron rust is a kind of substance of brownish red, it is so hard unlike iron, it is easy to be fallen off, one block of iron is complete
After getting rusty, 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
It obtains faster, iron is after 3 to 5 times Shi Huigeng heavy, about original of weight of getting rusty, metal rusting, quality and aesthetics
It will be influenced accordingly.Steel product is easily corroded in an atmosphere, the steel quantity that the whole world is lost by corrosion every year
It is very huge, in order to solve the corrosion of steel product, various anti-corrosion measures need to be often taken steel surface.It is industrial at present universal
The metal surface treating liquid used mainly has the function of derusting, antirust, decontamination, phosphatization, passivation etc., the existing single function of product
Can, also there is multi-functional unification.But it is at high cost in practical applications, or because cost of material is expensive；Or because degreasing and rust removal is not thorough,
Anti-corrosion performance, especially long-term anti-corrosion performance are poor；Or because complicated composition are unfavorable for tank liquor stability contorting；Or because in treatment process,
A large amount of acid mists are generated, contains the noxious materials such as strong acid, highly basic, heavy metallic salt, fluoride in product, jeopardizes equipment and operator
Health, therefore application have obvious limitation.
Currently, derusting method mainly has a Mechanical Method, chemical method two major classes, Mechanical Method be by manually striking shovel, polishing, the disadvantage is that
Large labor intensity, low efficiency, dust pollution are serious, and rust deposite is difficult to clean off completely, chemical method good, high-efficient, technique with effect
The advantages that easy to operate at low cost；But conventional chemical treatment rust remover be all it is acid, while removing rust is removed in cleaning,
Corrosion can be caused to metal surface, cause new corrosion, therefore, when using conventional acid rust remover, generally also needed simultaneously
Cooperate corrosion inhibiter to use, be not used only troublesome in poeration, and increase cost, and the discharge of cleaning solution will also result in ring after derusting
Border pollution.
Therefore it provides a kind of derusting effect is good, not damaged to metal base corrosion-free, no pollution to the environment is easy to operate,
Metal surface rust-removing agent at low cost is very necessary.
Summary of the invention
A kind of preparation method of neutral metal surface derusting cleaning agent, which is characterized in that this method is walked with following technique
It is rapid:
(1) A liquid is prepared: in reactor, it is added by following composition mass percentage concentration, ethyl alcohol: 52 ~ 56%, and phosphoric acid: 42 ~ 46%, oil

Sodium: 1 ~ 3.0%, glycine betaine: 3 ~ 6%, Glucosamine: 8 ~ 12%, the sum of each component is absolutely that stirring and dissolving is to get B liquid；
(3) C liquid is prepared: in reactor, it is added by following composition mass percentage concentration, water: 62 ~ 66%, and triisopropanolamine: 24 ~
28%, water-soluble defoaming agent: 8 ~ 12%, the sum of each component is absolutely, to be uniformly mixed to get C liquid；
(4) preparation of neutral metal surface derusting cleaning agent: being 1:1 by A liquid, B liquid and C liquid in reactor by volume: turning
Speed is 200 turns/min, stirs 2 hours to get neutral metal surface derusting cleaning agent.
The molar ratio of phosphoric acid described in step (1) and ethyl alcohol is 1:2.8 ~ 3.0.
The obtained neutral metal surface derusting cleaning agent application method of the present invention: by neutral metal surface derusting cleaning agent
Spraying is cleaned after reacting 40 ~ 60min on the metal surface, then clear water is rinsed well.
Advantages of the present invention and effect are:
(1) the obtained neutral metal surface derusting cleaning agent of the present invention, pH value is between 6.0 ~ 7.5；Cleaning agent and the waste liquid of cleaning
It is in neutrality, acid mist will not be generated, the structure of steel will not be corroded, while there have the presence of corrosion inhibiter oil acid based imidazolines to have to be anti-
Corrosivity prevents secondary corrosion, using safety and environmental protection, is suitble to promote.
(2) present invention obtains neutral metal surface derusting cleaning agent, and preparation process is simple, and condition is easily controllable, is produced into
