Abstract
The invention provides a metal corrosion inhibitor. The metal corrosion inhibitor is prepared from the following raw materials by weight: 5 to 11 parts of acetic acid, 3 to 8 parts of ethanol, 1.5 to 4 parts of a dispersant, 6 to 10 parts of polypropylene glycol, 3.5 to 9 parts of ethyl acrylate, 4.5 to 7 parts of methyl acrylate oligomer, 2.3 to 6 parts of aluminum tripolyphosphate, 1.5 to 3.6 parts of triethanolamine, 1.3 to 3.4 parts of polycarboxylic acid, 2.7 to 5.9 parts of ethylenediaminetetraacetic acid and 2.6 to 8.4 parts of tributyl phosphate. The invention has the following beneficial effects: the metal corrosion inhibitor can inhibit metal corrosion, exerts an obvious effect and has the advantages of a small application amount and low cost.
Description
Technical field
The present invention relates to a kind of metal corrosion inhibitor.
Background technology
Corrosion inhibitor forms by organic phospho acid, poly carboxylic acid, carbon steel corrosion inhibitor and copper inhibitor are composite, and the calcium carbonate in water, calcium sulfate, calcium phosphate etc. are all had good chelating dissemination and carbon steel, copper are had to good corrosion mitigating effect.Corrosion inhibitor corrosion inhibitor N is mainly used in recirculating cooling water system corrosion-mitigation scale-inhibition, and as recirculating cooling water systems such as power plant, chemical plant, petrochemical industry, iron and steel, corrosion inhibitor N-501 corrosion mitigating effect is good, scale inhibition power is strong.
Summary of the invention
For the deficiencies in the prior art, the technical problem to be solved in the present invention is, a kind of corrosion inhibitor is provided, and can suppress metallic corrosion, successful, and addition is less simultaneously, cost is lower.
For solving the deficiencies in the prior art, technical scheme of the present invention is: a kind of metal corrosion inhibitor, made by the raw material of following parts by weight:
Acetic acid 5-11 part, ethanol 3-8 part, dispersion agent 1.5-4 part, polypropylene glycol 6-10 part, ethyl propenoate 3.5-9 part, methacrylate oligomers 4.5-7 part, aluminium triphosphate 2.3-6 part, trolamine 1.5-3.6 part, poly carboxylic acid 1.3-3.4 part, ethylenediamine tetraacetic acid (EDTA) 2.7-5.9 part, tributyl phosphate 2.6-8.4 part.
The technical scheme of optimization of the present invention is, a kind of metal corrosion inhibitor is made up of the raw material of following parts by weight:
8 parts of acetic acid, 5 parts of ethanol, 2.7 parts of dispersion agents, 8 parts of polypropylene glycols, 5.8 parts of ethyl propenoates, 5.9 parts of methacrylate oligomers, 4.2 parts of aluminium triphosphates, 2.2 parts of trolamines, 2.1 parts of poly carboxylic acid, 4.3 parts of ethylenediamine tetraacetic acid (EDTA)s, 5.2 parts of tributyl phosphates.
The invention has the beneficial effects as follows, corrosion inhibitor of the present invention can suppress metallic corrosion, and addition is less simultaneously, cost is lower for successful.
