Abstract
The invention discloses a kind of inorganic acid rust removers and preparation method thereof, it is made of the raw material of following weight parts proportioning, 10 15 parts of hydrochloric acid, 5 10 parts of sulfuric acid, 35 parts of citric acid, 57 parts of lauryl sodium sulfate, 12 parts of methenamine, 0.5 1 parts of calgon, 60 80 parts of deionized water.Sulfuric acid is first dissolved in deionized water, adds hydrochloric acid, citric acid, methenamine, calgon, lauryl sodium sulfate is finally added under heating conditions, dissolving is complete.Finished product is obtained, the inorganic acid rust remover in the present invention can reduce inorganic acid to corrosion of metal, effectively inorganic acid can be inhibited to escape, and reduce the health hazards to operating personnel, and derusting ability is strong, derust fast.
Description
Technical field
The present invention relates to rust remover technical field, especially a kind of inorganic acid rust remover and preparation method thereof.
Background technology
Ferrous metal (steel) is placed under outdoor or open-air condition and gets rusty easily, and not only influences appearance, can also influence to spray
Being normally carried out for the techniques such as paint, bonding, such as handles, but will cause scrapping for material not in time, leads to unnecessary economic damage
It loses.
Inorganic acid rust remover is also referred to as pine rust agent, it can form lasting anti-corrosion protection in exposed metal surface, prevent
Only new corrosion is formed.It can be widely applied to manufacturing industry, construction industry, repairing trades, traffic, the energy, electric power, oil and mine
A variety of industries such as exploitation are suitable for mechanical equipment, vehicle, ship, ordnance, hardware tool, building template, metal spare and accessory parts etc.
The derusting of steel.
There is very strong corrosivity, when use to generate a large amount of gas for existing inorganic acid rust remover, the inorganic acid used
It steeps, the inorganic acid in rust remover enters air with bubble, is damaged to the health of operating personnel.
Invention content
The purpose of the present invention is to provide a kind of inorganic acid rust remover and preparation method thereof, and inorganic acid of the present invention removes
It becomes rusty agent, derusting ability is strong, derusts fast, reduces inorganic acid to corrosion of metal, it is suppressed that the spilling of inorganic acid reduces pair
The health hazards of operating personnel.

1 part, 80 parts of deionized water 60-.
The mass fraction of inorganic acid rust remover above-mentioned, the hydrochloric acid is 36-38%.
The mass fraction of inorganic acid rust remover above-mentioned, the sulfuric acid is 95%-98%.
The preparation method of inorganic acid rust remover, it is characterised in that：It is prepared according to the following steps,
A, sulfuric acid is added along wall in deionized water, is stirred while adding, added and continue stirring 10 minutes, obtain A product；
B, hydrochloric acid, citric acid, methenamine, calgon are added into A product, stirring is complete to dissolving, and obtains B product；
C, lauryl sodium sulfate is added into B product, stirs 15-20 minutes, obtains finished product.
B product are heated to 0 DEG C of 60-8 in step c by the preparation method of inorganic acid rust remover above-mentioned.
Compared with the prior art, in the present invention, the calgon being added in inorganic acid rust remover is a kind of corrosion inhibiter,
Inorganic acid can be reduced to corrosion of metal；The lauryl sodium sulfate being added in inorganic acid rust remover is a kind of surface-active
Agent can be adsorbed in acid solution interface, form firm liquid film, and liquid film forms certain froth bed under the action of bubble buoyancy,
Effectively inorganic acid can be inhibited to escape, reduce the health hazards to operating personnel, the inorganic acid rust remover in the present invention removes
Rust ability is strong, derusts fast.
