Abstract

The invention discloses a quaternary polymeric form corrosion and scale inhibitor which consists of maleic anhydride, hydroxy-propyl acrylate, acrylic acid, sodium alkyl sulfonate, sodium peroxydisulfate, sodium hypophosphite, isopropyl alcohol and water. The invention also discloses a preparation method of the quaternary polymeric form corrosion and scale inhibitor. The corrosion and scale inhibitor has good performance in inhibiting calcium carbonate scale, calcium sulphate scale, calcium phosphate scale and zinc scale and good dispersing performance for dispersing ferric oxide and is also characterized by corrosion resistance, high temperature resistance, stable molecule structure and low phosphorus content; the whole production process has no emission of 'the three wastes'. The technique of the product of the invention for treating circular cooling water is simple and the product of the invention has the advantages of little dosage, low cost, good effect and good economic benefit and wide social benefit.

Description

technical field

[0001] The invention belongs to the field of chemical industry, and relates to a quaternary polymerization type corrosion and scale inhibitor used in industrial cooling water systems and a preparation method thereof. Background technique

[0002] With the scale of industrial production and the rapid increase of population, water resources are seriously scarce. Since cooling water consumption accounts for 60-70% of industrial water consumption, it is particularly important to save cooling water reasonably. The main way to save cooling water is to increase the recycling rate of cooling water and increase the concentration of cooling water, but this will bring serious corrosion and scaling problems to the cooling water system, and it also poses a problem for water treatment chemicals. Higher requirements are imposed to ensure the normal operation of the circulating cooling water system under the conditions of high hardness, high alkalinity, high chloride ions o...
