Efficient low-phosphorus macromolecule scale inhibition corrosion inhibitor and preparation method thereof

Abstract

The invention relates to an efficient low-phosphorus macromolecule scale inhibition corrosion inhibitor and a preparation method thereof, wherein the components comprise, by mass, 40-60 parts of 2-hydroxyphosphonoacetic acid, 80-120 parts of 2-phosphonic acid butane-1,2,4-tricarboxylic acid, 280-320 parts of a polyacrylate-AMPS copolymer, 70-100 parts of polyaminopolyether methylene phosphonic acid, 60-85 parts of a zinc salt, 10-30 parts of hydrochloric acid, 30-60 parts of a maleic anhydride copolymer, 10-30 parts of sodium gluconate, and 295-320 parts of deionized water. The preparation method comprises: pumping 2-hydroxyphosphonoacetic acid, 2-phosphonic acid butane-1,2,4-tricarboxylic acid, a polyacrylate-AMPS copolymer and polyaminopolyether methylene phosphonic acid into a reaction kettle by using a reciprocating vacuum pump, stirring for 20 min, pumping a maleic anhydride copolymer, continuously stirring, adding a zinc salt, deionized water and hydrochloric acid to another container, completely dissolving, pumping into the reaction kettle, stirring for 10 min, adding sodium gluconate, sealing, stirring for 15-30 min, and discharging the material. According to the present invention, the technical purposes of water saving, low cost, low phosphorus and environmental protection can be achieved.

Description

technical field [0001] The invention relates to an industrial circulating water treatment process, which belongs to the scale and corrosion inhibition technology, in particular to a high-efficiency and low-phosphorus macromolecular scale and corrosion inhibitor and a preparation method thereof. Background technique [0002] The industrial circulating water system is the basic guarantee for the normal operation of industrial enterprises. Scaling, corrosion, and biological slime blockage of circulating water are the main hazards of heat exchange equipment damage and efficiency reduction. Scaling, corrosion, and fouling, which are common in heat exchange equipment in the system, will reduce production efficiency and consume fuel. The light ones will reduce the heat transfer efficiency of the heat exchanger and affect production. In severe cases, it is necessary to stop production for maintenance and even corrode and perforate the heat exchange surface, causing a series of econo...
