Abstract
The invention relates to a corrosion inhibitor, which is mainly used for corrosion inhibition in a continuous acid cleaning technology of a cold-rolled sheet. The corrosion inhibitor comprises the following components in percentage by weight: 10-25% of hexamine, 0-10% of vinylamine, 0-10% of ethanolamine, 0-3% of alkynol alkoxylate, 0-4% of oxalic acid, 2-5% of additive and 43%-88% of water. The corrosion inhibitor can effectively inhibit corrosion, improve the brightness of the surface of a sheet, prolong the use period of an acid liquid and has a certain rust-proof property.
Description
Technical field
The present invention relates to a kind of corrosion inhibitor, especially relate to the corrosion inhibition of cold rolled sheet continuous pickling process, belong to steel product and material surface treatment industry technical field.
Background technology
Along with science and technology development, industries such as automobile, household electrical appliances are more and more higher to the quality and the quantity demand of cold rolled sheet, and domestic in recent years cold-reduced sheet industry obtains very big development.At present, cold rolled sheet generally uses the continuous pickling production line, and pickling tank generally is divided into three sections, and working concentration about 25% or above hydrochloric acid carry out continuous pickling under the temperature more than 70 ℃.Pickling under the condition of high temperature and high acidity prevents that hydrochloric acid is very important to the overpickling of thin plate, and is general by using the corrosion inhibitor head it off.At present, multiple bite inhibitor is arranged both at home and abroad, but when being applied in the thin plate continuous pickling technology, mostly have after short, the pickling of corrosion inhibition rate variance, life-span defectives such as thin plate obfuscation.Above deficiency at product existence on the market, the present invention proposes a kind of corrosion inhibitor, is characterised in that the good corrosion mitigating effect of maintenance under the condition of the high acidity of high temperature, the thin sheet surface light after pickling, have certain rust-preventing characteristic after the washing oven dry, can avoid the preceding degree of depth corrosion of reworking.
Summary of the invention
The invention provides a kind of corrosion inhibitor, be mainly used in corrosion inhibition in the cold rolled sheet continuous pickling process, formulated by following components in weight percentage:
Vulkacit H 10～25%
Vinyl-amine 0～10%
Thanomin 0～10%
Alkynol alcoxylates 0～3%
Oxalic acid 0～4%
Additive 2～5%
Water 43～88%
Above-mentioned described a kind of corrosion inhibitor is the reddish-brown transparent liquid.Each components description is as follows:
1. vulkacit H can be adsorbed on the steel sheet surface, stops or slows down acid to the corrosion of matrix.
2. vinyl-amine is one or more combinations that comprise in triethylene tetramine, tetraethylene pentamine, five ethene hexamines, the polyethylene polyamine.
3. thanomin is one or more the combination that comprises in Monoethanolamine MEA BASF, diethanolamine, the trolamine, and this component can make the sheet material after the pickling have certain rust-preventing characteristic, avoids the degree of depth corrosion before the reworking.
4. the alkynol alkoxy compound is one or more mixtures that comprise in butynediol propoxylated glycerine, BEO, propiolic alcohol ethoxylate, the propiolic alcohol propoxylated glycerine, this component is mainly used in inhibition and light effect, can improve the luminance brightness of thin plate after the pickling.
5. oxalic acid has certain reductibility, can quicken rust cleaning.
6. additive is non-ionic type or both sexes class tensio-active agent, comprises one or more compounds in fatty alcohol-polyoxyethylene ether (n=7～10), the AMONYL 380LC, is used to improve the perviousness of hydrochloric acid, improves pickling speed, suppresses the acid consumption.
Best composition of the present invention and content are:
Vulkacit H 18%
Vinyl-amine 4%
Thanomin 4%
Alkynol alcoxylates 3%
Oxalic acid 2%
Additive 3%
Water 66%
The invention is characterized in:
1, under high temperature and high acidity condition, can keep good corrosion inhibition performance lastingly, effectively reduce the excessive erosion of hydrochloric acid to thin plate.
2, the thin plate after pickling, surface-brightening, no dust.After the washing oven dry, have certain rust-preventing characteristic, can avoid the preceding degree of depth corrosion of reworking.
3, consumption is few, generally adds according to 2 ‰-1% of acid solution total mass and uses, and need not supplemental production midway, can prolong about 1～2 cycle in hydrochloric acid life-span.
Embodiment
According to described compound method preparation corrosion inhibitor of the present invention, each component and content are respectively: vulkacit H 18%, vinyl-amine 4%, thanomin 4%, alkynol alcoxylates 3%, oxalic acid 2%, additive 3%, water 66%.Make corrosion inhibitor of the present invention, its quality index is:
| Outward appearance | Deep yellow is to brown transparent liquid |
| Density (20 ℃, g/ml) | 1.040 |
| PH value (1% aqueous solution) | 7.2 |
| Solid content | 30％ |
Embodiment 1:
Experiment condition: heat under 80 ℃ of water bath with thermostatic control conditions, hydrochloric acid mass concentration 25%, the experiment steel plate material is Q235, rusty degree is B.Experimental result is as follows:
| Use the present invention | Do not use the present invention | |
| Corrosion inhibition rate % | 80％ | - |
| Surface quality | Light | Obfuscation has dust |
| The dynamic rust cleaning time (second) | 12～16 | 13～15 |
By above data as can be seen, when the present invention has higher corrosion mitigating effect, cleaning speed there is not influence.There are not phenomenons such as dust in steel sheet light after the pickling.
Embodiment 2:
For further specifying effect of the present invention, describe in conjunction with following practical application.
The continuous pickling technology of this product application new big-and-middle thin plate company limited in the Wuxi uses addition to be 4 ‰ of hydrochloric acid quality.According to investigations, compare with Japanese firm's " bite inhibitor ", the thin plate after the pickling of the present invention is brighter, prolongs acid solution work-ing life to 1 simultaneously～2 cycles.The result shows that the present invention is applied to can effectively improve the quality of products in the cold rolled sheet acid cleaning process, saves production cost simultaneously.
