Abstract
The invention discloses steel on-line water-based rust inhibitor. The rust inhibitor is prepared from, by weight, 6-10% of nitrous acid diisopropylamine, 3-5% of sodium caseinate, 0.5-1.5% of potassium hydroxide, 1-2% of thiourea, 0.5-2.0% of isopropanol, 0.5-1.5% of ricinoleic acid, 0.1-0.15% of pentaerythritol oleate, 0.05-0.1% of ammonium persulfate, 0.05-0.08% of polyvinylpyrrolidone, 0.05-0.08% of sorbitol, 0.01-0.05% of tetramethyl tetravinyl cyclotetrasiloxane and the balance water. The steel on-line water-based rust inhibitor is remarkable in rust prevention effect,, long in rust prevention time, low in cost, free of pollution, high in safety, short in treatment time and simple and efficient in treatment process. Steel treated with the treatment agent has good product appearance, quite considerable economic benefits, a wide application prospect and a wide market space.
Description
Technical field
The present invention relates to the online water-based rust inhibitor of a kind of iron and steel, the invention still further relates to the preparation method of the online water-based rust inhibitor of a kind of iron and steel.
Background technology
Iron and steel, as important starting material, is widely used in during bridge, harbour, dam, harbour, platform, highway, industry and the various modernization project such as covil construction build, playing vital effect in national economy.Along with the expansion of capital construction scale in recent years, the usage quantity of iron and steel is increasing, also more and more higher to its corrosion proof requirement.Owing to the environmental influence such as to make moist, the problem that storage time long ubiquity easily gets rusty when Finished Steel ironware is deposited, cause visual appearance difference and cause sales difficulty, bringing financial loss to enterprise.Meanwhile, corrosion will produce detrimentally affect to the performance of iron and steel, directly use band rust iron and steel can reduce the performance of concrete integral structure, and before using, rust cleaning will increase cost and operation.
At present, increasing iron and steel producer adopts rust-preventive agent to carry out online rotproofing to the surface of finished product iron and steel.Rust-preventive agent mainly comprises water-based antirust and slushing oil.Ortho-water based anti-rusting agent, due to containing carcinogenic substances such as Sodium Nitrites, will damage the healthy of workman, simultaneously serious environment pollution; Slushing oil can reduce steel surface and concrete bond stress, has a strong impact on the Performance and quality of iron and steel.Meanwhile, existing water-based antirust rust-proof life is shorter, can only be used for inter process short-term rust prevention.At present, the report in prior art not in the water-based rust inhibitor of iron and steel online treatment.Therefore, work out a kind of online treatment water-based rust inhibitor that is efficient, environmental protection and become a kind of active demand.
Summary of the invention
First technical problem to be solved by this invention be for the state of the art provide a kind of energy online treatment of environmental protection, the iron and steel rust inhibitor of water-based.
Second technical problem to be solved by this invention be for the state of the art provide a kind of energy online treatment of environmental protection, the preparation method of the iron and steel rust inhibitor of water-based.
The present invention solves the technical scheme that above-mentioned first technical problem adopt: the online water-based rust inhibitor of a kind of iron and steel, be made up of the raw material of following weight percent: nitrous acid Diisopropylamine 6 ~ 10%, Sodium Caseinate 3 ~ 5%, potassium hydroxide 0.5 ~ 1.5%, thiocarbamide 1 ~ 2%, Virahol 0.5 ~ 2.0%, ricinolic acid 0.5 ~ 1.5%, PETO 0.1 ~ 0.15%, ammonium persulphate 0.05 ~ 0.1%, polyvinylpyrrolidone 0.05 ~ 0.08%, Sorbitol Powder 0.05 ~ 0.08%, t etram-ethyltetravinylcyclotetrasiloxane 0.01 ~ 0.05%, surplus is water.
Wherein, iron and steel online water-based rust inhibitor is made up of the raw material of following weight percent: nitrous acid Diisopropylamine 8%, Sodium Caseinate 4%, potassium hydroxide 1.5%, thiocarbamide 1.5%, Virahol 1.5%, ricinolic acid 1.0%, PETO 0.12%, ammonium persulphate 0.075%, polyvinylpyrrolidone 0.065%, Sorbitol Powder 0.065%, t etram-ethyltetravinylcyclotetrasiloxane 0.03%, surplus is water.
The present invention solves the technical scheme that above-mentioned second technical problem adopt: the preparation method of the online water-based rust inhibitor of a kind of iron and steel, it is characterized in that, comprise the following steps: it is miscible nitrous acid Diisopropylamine and Sodium Caseinate to be added in a kettle. water, and then add potassium hydroxide and thiocarbamide, solution left standstill 1 ~ 5 hour after stirring and dissolving; Leave standstill 10 ~ 50 minutes after stirring and dissolving after adding Virahol, ricinolic acid, PETO, ammonium persulphate, polyvinylpyrrolidone, Sorbitol Powder, t etram-ethyltetravinylcyclotetrasiloxane successively, obtain the online water-based rust inhibitor of iron and steel.
Compared with prior art, the invention has the advantages that:
1, pass through iron and steel online treatment, the chromium-free passivating film of one deck densification is generated rapidly when rust inhibitor contacts with steel surface, thus protective effect is formed to steel surface, and this passive film and concrete firm binding force, improve surface and concrete bond stress, ensure that the Performance and quality of iron and steel after treatment;
2, the Virahol used in the online water-based rust inhibitor of iron and steel of the present invention, ricinolic acid, PETO are as promotor, synergy, the formation speed of passive film at steel surface can be accelerated, within the time of 2 ~ 5 seconds, form chromium-free passivating film at steel surface, thus meet the online rotproofing of iron and steel;
3, ammonium persulphate, polyvinylpyrrolidone, Sorbitol Powder, the adding of t etram-ethyltetravinylcyclotetrasiloxane, greatly can improve density and the thickness of chromium-free passivating film, thus improve the solidity to corrosion of steel surface after online treatment, ensure that simultaneously steel surface and concrete bond stress unaffected.
Compared with prior art, rust-proof effect is remarkable, and antirust time is long, and cost is low, pollution-free, and security is high, and the treatment time is short, and treatment process is simply efficient in the present invention.Iron and steel after treatment agent process of the present invention has good product appearance, has appreciable economic benefit and wide application prospect and the market space.
