The invention provides a production method of sorbitol and maltitol inhibitor. The sorbitol and maltitol inhibitor comprises, by weight percent, 2-3% of sodium molybdate, 2-3% of alkyl benzimidazole, 6-7% of sodium benzoate, and the balance of sorbitol and maltitol. The ratio of the sorbitol to the maltitol in the balance is 1:1. The production method includes mixing the maltitol and the sorbitol, heating to 70 DEG C, mixing well, adding the alkyl benzimidazole, continuing mixing, heating to 90 DEG C, then heating to 110 DEG C, continuing mixing for 2 hours, chelating and combining, allowing for cooling to 100 DEG C, mixing, adding active carbon for discoloration, mixing again, allowing for cooling to below 70 DEG C, and cooling and packing. The sorbitol and maltitol inhibitor is applicable to various medium corrosion environments, is applicable to black and nonferrous metals, and is water-soluble, non-corrosive, nonflammable and low-toxicity. The production method is free of emission of waste gas, waste water and waste residue, is low in noise and low in energy consumption and is widely applicable.

Description

A kind of sorbyl alcohol and maltose alcohol inhibiter and preparation method thereof
Technical field
The present invention relates to a kind of mechanical surface protection engineering, a kind of rust preventive for metal surface and manufacture method thereof, be specifically a kind of be inhibiter of making of base-material and preparation method thereof by sorbyl alcohol and maltose alcohol.
Background technology
Inhibiter, English name: anti-corrosive; Corrosion inhibitor is a kind ofly under lower concentration, can stop or reduce the material that metal corrodes in surrounding medium.Inhibiter is also known as stopping agent, stopping agent, rust-preventive agent or corrosion inhibitor.Inhibiter resist technology has developed into an important anticorrosion technique, is widely used in the departments such as oil, chemical industry, metallurgy, machinofacture, communications and transportation and power.At neutral medium; as the inhibiter of the equipment of boiler feed water, recirculated cooling water, pipeline; the inhibiter that general employing 2-HPAA (HPAA) and organophosphate are main flow; this inhibiter; nontoxic or low toxicity, has good provide protection to various metals, still; its purposes is single, can only be applied to a kind of dielectric corrosion environment.In fields such as Metal smelting, metal processing and manufacturings, still continuity is used the inhibiter taking chromic salt, nitrite, inorganic phosphate etc. as main flow at present, the finished product of this type of inhibiter, also be that purposes is single, not to be exclusively used in ferrous metal, only be exactly for non-ferrous metal, and it is suitable for the corrosive deposit in single surrounding medium, as neutral medium, as boiler feed water and circulating cooling wetting system pipeline, or as acidic medium, as the acid dip solution of descale hydrochloric acid and the front plating piece rust cleaning of plating use etc., be not suitable for the corrosive deposit in multiple surrounding medium.
Before technical solution of the present invention completes, the inhibiter of not seeing the method manufacture identical with technical solution of the present invention uses in people's work, the inhibiter of not seeing the method manufacture identical with technical solution of the present invention has sale on market, also do not see the method identical with technical solution of the present invention, and the inhibiter that adopts said method to manufacture is on the books in any document.
Summary of the invention
The object of the present invention is to provide one to can be used in medium corrosive environment, and be not only applicable to ferrous metal, also be applicable to the inhibiter of various non-ferrous metals, it is a kind of water-soluble, non-corrosiveness, without inflammable and explosive property, hypotoxic safe and reliable inhibiter, provide in a kind of production process without waste gas, without waste water, without waste sludge discharge, the inhibiter of the environmental protection that noise is low, energy consumption is low, inhibition efficiency than the inhibiter of any Single Medium corrosive environment and special purpose improves greatly, and corrosion inhibition is strengthened greatly.
For achieving the above object, the present invention adopts following technical proposals:
A manufacture method for sorbyl alcohol and maltose alcohol inhibiter,
Its compositions in weight percentage is:
In reactor, maltose alcohol and sorbyl alcohol are mixed, be heated to 70 DEG C, stir, add alkyl benzimidazole, continue to stir, be heated to 90 DEG C, be then heated to 110 DEG C, continue to stir 2 hours, carry out chelating composite, be cooled to 100 DEG C, stir, add activated carbon decolorizing, then stir, be down to below 70 DEG C, carry out cooling, packaging, complete the manufacture of product.
Said Sodium orthomolybdate is a kind of inorganic inhibitor, it is anodic corrosion inhibitor, it is inorganic strong oxidizer, its effect is at positive column, metallic surface and Action of Metal Ions, generating oxide compound oxide film covers and on anode, forms protective membrane, suppressed metal and dissolved in water, anodic reaction is controlled, and anode is passivated; Sodium Benzoate is a kind of organic inhibitor, is cathode type inhibiter, is precipitation membranous type inhibiter, and its effect is with relevant ionic reaction in medium and generates the precipitation membrane that has certain protective role in metallic surface, thereby stops the material of metallic corrosion; Alkyl benzimidazole is the nitrogenous surface-active organic inhibitor that has, in its molecule, there are two kinds of incompatible polar groups, can be adsorbed on clean metallic surface and form unimolecular film, they can be in anode film forming, also can be at cathode filming, stop water and oxygen in water to the diffusion of metallic surface, played corrosion inhibition.That oxide film, precipitation membrane and the adsorption film covering metal surface that three kinds of materials of said Sodium orthomolybdate, Sodium Benzoate and alkyl benzimidazole form forms is tight, complete, three-layer protection film firmly, produces good synergistic function.Alkyl benzimidazole can not be directly water-soluble, but can be dissolved in sorbyl alcohol and maltose alcohol, thereby reach synergy, integrated antirust object.Sorbyl alcohol, maltose alcohol, alkyl benzimidazole, Sodium Benzoate and Sodium orthomolybdate itself is exactly good inhibiter to cast iron, carbon steel, copper, aluminium etc., after composite their chelating, use any said inhibiter greatly to improve inhibition efficiency than single, comprehensive rust inhibition obviously strengthens.
The present invention can directly use, also can be using water as solvent, configure the solution of various concentration, as the corrosion inhibitor solution of 0.3 mg/litre.
Due to this product at low temperatures viscosity increase, when use, this product can be heated to 30-50 DEG C.
The present invention has some effects and positively effect below:
The test experience report that the inventor adopts a kind of sorbyl alcohol of said the present invention and maltose alcohol inhibiter and preparation method thereof to carry out in laboratory below:
