Abstract

The invention provides a nano corrosion and scale inhibitor and a preparation method thereof. The nano corrosion and scale inhibitor comprises the following raw material components in parts by weight:30 parts of nano calcium carbonate, 5 parts of nano strontium sulfate, 8 parts of a carboxylic copolymer, 8 parts of metallic salt, 5 parts of phosphorus pentoxide, 20 parts of amino ether phosphonicacid, 5 parts of etidronic acid, 3 parts of polymaleic acid, 5 parts of mercaptobenzothiazole, and 2 parts of sodium hypophosphite. The nano corrosion and scale inhibitor has the advantages of beingconvenient to store and transport, low in metal corrosion in boiler, pipeline and pressure vessel washing, high in antisludging capacity, safe to use, and small in environmental pollution.

Description

technical field [0001] The invention relates to a corrosion and scale inhibitor, in particular to a nanoscale corrosion and scale inhibitor and a preparation method thereof. Background technique [0002] At present, acidifying the formed scale salt is a commonly used method to eliminate carbonate scale, but for sulfate scale, especially barium sulfate and strontium sulfate scale, it is difficult to remove by this method. People often use scale inhibitors to prevent the formation of barium sulfate and strontium sulfate scale salts, but the addition of scale inhibitors is often a kind of pollution to water sources. Adding a strong chelating agent such as disodium ethylenediaminetetraacetic acid (EDTA) to the solution containing barium and strontium ions can delay the scaling speed of barium sulfate and strontium sulfate scale, but this method is costly. Contents of the invention [0003] The purpose of the present invention is to overcome the above disadvantages, to provide...
