Abstract
The invention discloses a metal corrosion inhibitor. The metal corrosion inhibitor is prepared from, by weight, 22-24 parts of amino tri(methylene phosphonic acid), 8-10 parts of 1-hydroxy ethylidene-1,1-diphosphonic acid, 8-12 parts of sodium silicate, 2-4 parts of phosphoric acid, 3-5 parts of polyacrylamide, 1-3 parts of polyaspartic acid, 3-6 parts of sodium gluconate, 3-6 parts of zinc sulfate, 3-6 parts of sodium bicarbonate, 6-9 parts of sodium chloride, 4-6 parts of ethylene glycol, 0.3-0.5 part of a surface active agent and 30-40 parts of deionized water. The metal corrosion inhibitor is good in water solubility and remarkable in corrosion inhibition effect, and has high corrosion resisting capacity.
Description
Technical field
The invention belongs to corrosion inhibition for metal technical field, it is specifically related to a kind of metal inhibitor.
Background technology
Inhibiter is a kind of when being present in environment (medium) with suitable concentration and form, it is possible to prevent or slows down chemical substance or the mixture of material corrosion, corrosion inhibitor can also be called, water coolant is the general facilities that industrial enterprise is indispensable, in use procedure, meeting erode metallic surfaces, it is necessary to add inhibiter and prevent metallic corrosion. The most copper inhibiter used now is more or less all toxic, such as conventional BTA, imidazoles, thiazole, carbazole, aniline, thiocarbamide etc., owing to the toxicity of these inhibiter is to bringing numerous inconvenience in application process.
Summary of the invention
It is an object of the invention to provide a kind of metal inhibitor, better water-soluble, corrosion mitigating effect is remarkable, has very strong resistance to corrosion.
The technical solution used in the present invention is, a kind of metal inhibitor, is made up of the raw material of following weight part number: Amino Trimethylene Phosphonic Acid 22-24 part, 1-Hydroxy Ethylidene-1,1-Diphosphonic Acid 8-10 part, water glass 8-12 part, phosphoric acid 2-4 part, polyacrylamide 3-5 part, poly aspartic acid 1-3 part, Sunmorl N 60S 3-6 part, zinc sulfate 3-6 part, sodium bicarbonate 3-6 part, sodium-chlor 6-9 part, ethylene glycol 4-6 part, tensio-active agent 0.3-0.5 part, deionized water 30-40 part.
The present invention has the following advantages: better water-soluble, and corrosion mitigating effect is remarkable, has very strong resistance to corrosion.
