Abstract

The invention relates to a fully organic corrosion and deposit inhibitor for industry water treatment and a fabrication method to be concerned, which is fabricated by the weight percentage compositions of the following elements: 20 percent to 30 percent of acrylate-acrylate copolymer, 12 percent to 20 percent of sulfonic acid copolymer, 5 percent to 10 percent of polyepoxysuccinic acid, 0.6 percent to 0.9 percent of benzotriazole, 10 percent to 15 percent of hydroxy ethylidene diphosphoric acid, 2-butane phosphate 1,2,4, 15 percent to 25 of percent tricarboxylic acid, 2 percent to 4 percent of zinc salt and deionized water; the invention is the corrosion and deposit inhibitor for industry water, which is fabricated by acrylate-acrylate copolymer, sulfonic acid copolymer, polyepoxysuccinic acid, hydroxy ethylidene diphosphoric acid, 2-butane phosphate 1,2,4, tricarboxylic acid (PBTCA), benzotriazole and zinc salt, the invention solves the problems of complicated operation for site user and high cost; after testing, the scale removing rate of the invention is over 95 percent.

Description

technical field [0001] The invention relates to water treatment technology, in particular to an all-organic corrosion and scale inhibition industrial water treatment agent and a preparation method thereof. Background technique [0002] At present, the industrial water treatment agents produced in my country cannot contain the functions of scale inhibition, corrosion inhibition and pre-filming at the same time. Users need to add scale inhibitors, corrosion inhibitors and pre-filming agents when using them on site. The operation is cumbersome and the cost is relatively high. high. Contents of the invention [0003] The present invention aims to solve the problems that scale inhibitors, corrosion inhibitors and pre-membrane agents are added when the existing industrial water treatment agents are used on site, the operation is cumbersome and the cost is relatively high, and an all-organic corrosion and scale inhibition industrial water treatment agent is provided. agent.
