Abstract
The invention provides a preparation method of water soluble copper corrosion inhibitor, belongs to the technical field of chemical industry, and aims to provide a preparation method of compound corrosion inhibitor which is simple in technological process, low in production cost, stable in quality, and efficient in copper corrosion inhibition. The preparation method of the water soluble copper corrosion inhibitor is characterized in that organic azole which mainly comprises benzotriazole and methyl phenyl propyl triazole nitrogen is compounded with composite amines, wherein the composite amines are mixture mainly compounded by triethanolamine and diisopropylamine according to a certain ratio. The technological process of production of the preparation method is simple, product quality is stable, and the crustation inhibitor efficiency of corrosion inhibition is up to 98%. Meanwhile the production process of the preparation method is an environment friendly cleaning process, free of discharging of three industrial wastes, easy and convenient to operate, low in production cost, and suitable for industrialized scale production.
Description
Technical field
The present invention relates to a kind of preparation method of water-soluble copper inhibiter, belong to chemical technology field.
Background technology
Copper is widely used owing to having good machinery and heat conductivility, but copper corrosion is also more serious in long-term use procedure, and the consumption of often being only Copper Sea Waters just reaches 100,000 tons.And the stopping production that causes due to etching problem or product leakage and pollution loss larger, therefore must protect it.In various guard methods, low and be easy to control to add the inhibiter cost, thereby be widely used.In existing copper inhibitor, mostly be azole and imidazoles.In commercially available copper inhibitor, the concentration of BTA is generally 20mg/L, large usage quantity, use cost is higher, for reducing costs, at present the scientific research personnel is setting about studying the lower inhibiter of new price and is replacing, and also has the researchist to attempt carrying out with several inhibiter composite, utilizes synergistic effect between inhibiter to reduce the consumption of inhibiter, improve inhibition efficiency, reduce costs.At present, the copper inhibitor in industrial application mainly contains: to contain the N compound as main nitrogen azoles type, amine type and pyridine type inhibiter, as benzotriazole, hexamethylenetetramine etc.; Containing S, N compound as main thiazole type inhibiter, as 2-mercaptobenzothiazole (MBT) etc.; To contain N, O compound as main amine aldehyde condensate type inhibiter.When using separately wherein a kind of inhibiter, weak point is arranged all.Low-phosphorous and without phosphorus water treatment formula has application to a certain degree abroad, and is rare to report with the application of composite water soluble rust inhibitor by a certain percentage such as organic azole and organic amine at home.
For adapting to environmental protection needs and the market requirement, the present invention proposes a kind of preparation method of water-soluble copper inhibiter, the Compound Water dissolubility copper inhibitor that is consisted of with certain proportion by benzotriazole, methyl phenylpropyl alcohol triazole and organic amine, overcome the poor difficulty that waits single variety to exist of solubility property, can mix with arbitrary proportion with water, copper, aluminium or X alloy material there are good corrosion inhibition, can use with organophosphorus and polymer combination.
Summary of the invention
The object of the present invention is to provide and a kind ofly have that technical process is simple, production cost is low, steady quality, the preparation method of the complex copper inhibiter that the copper inhibition efficiency is high.
Its technical scheme is: the Compound Water dissolubility copper inhibitor that is made of with certain proportion benzotriazole, methyl phenylpropyl alcohol triazole and compound organic amine; The mixture that benzotriazole and methyl phenylpropyl alcohol triazole form and the quality proportioning of compound By Amine Solutions are: compound a kind of of 5-15: 95-85; In the mixture that benzotriazole and methyl phenylpropyl alcohol triazole form, the quality proportioning of benzotriazole and methyl phenylpropyl alcohol triazole is: compound a kind of of 40-70: 60-30; Compound organic amine is the mixture for trolamine and Diisopropylamine, and the quality proportioning is: 30-60: compound a kind of of 70-40.
Product water solution is weakly alkaline; can be dissociated into negative ion in water, then generate a kind of insoluble stable comple with the cupric ion complexing, this complex compound is adsorbed on the metallic surface; form very firmly surface film of one deck, protection copper and other metal are avoided the corrosion of atmosphere and hazardous medium.In the scope of PH7.0-10, satisfactory stability is arranged, bitter, odorless.Can be miscible with any ratio with water. copper, aluminium or X alloy material there are good corrosion inhibition.
Its technique effect is: phenylpropyl alcohol triazole and methyl phenylpropyl alcohol triazole are composite, and function is replenished mutually; Replace sodium hydroxide with compound organic amine, quality is more stable, and compound organic amine also has corrosion mitigating effect.Simultaneously, its production technique is the environment-friendly type cleaning procedure, and without the three industrial wastes discharging, easy and simple to handle, production cost is low, is fit to commercial scale production.
Embodiment
Embodiment 1: get trolamine 3 grams, Diisopropylamine 7 grams dissolve in and are re-dubbed the compound 10% organic amine aqueous solution in 90 gram water; Get benzotriazole 7 gram methylate phenylpropyl alcohol triazole 4 grams again and be dissolved in 89 gram 10% organic amine compound aqueous solutions, stirring gets final product.
