Abstract

The invention provides a multi-metal surface protective agent and a preparation method and application thereof. The multi-metal surface protective agent comprises the following raw materials in parts by weight: 15-21 parts of a sealing agent, 43-55 parts of a film-forming agent, and 9-5 parts of a catalyst 15 parts and 17-23 parts of pH regulator; wherein, the raw materials of the film-forming agent include organic acids, alcohol amine compounds, benzotriazole and deionized water; the raw materials of the sealing agent include organic dibasic acids , alcohol amine compounds, ammonium citrate and deionized water; the catalyst includes citric acid and lactic acid; the pH adjuster includes methyl benzotriazole and triethylamine. The polymetallic surface protective agent provided by the invention can be applied to the circulating water system, has no requirement on the water quality in the water circulating system, is suitable for water quality such as deionized water, soft water, groundwater and surface water, and has strong resistance to hard water, good The reserve alkalinity and the performance of acid and alkali resistance and high temperature resistance.

Description

technical field [0001] The invention relates to the technical field of water circulation systems, in particular to a multi-metal surface protective agent and a preparation method and application thereof. Background technique [0002] With the rapid development of economy and the rapid increase of population, water shortage has become an important factor restricting my country's economic construction and development. In my country, a large amount of water resources are used and consumed in industrial circulating water and urban heating circulating water. However, because water contains colloids, suspended solids, soluble salts such as calcium, magnesium, potassium and other oxidizing substances and dissolved gases, In the process of application, the circulating water inevitably produces scaling (calcium carbonate, calcium sulfate, barium sulfate, etc.), and at the same time, the problems of bacteria breeding and corrosion under the scale are also more prominent. Therefore, it ...
