Abstract

The invention relates to a green and environment-friendly compound scale and corrosion inhibitor agent and its preparation method. The composition and mass parts of the agent are as follows: polyamino polyether group methylene phosphonic acid: 10-20 parts, polyol phosphate : 15-25 parts, polyepoxysuccinic acid: 5-15 parts, acrylic acid-acrylate-sulfonate copolymer: 10-20 parts, anhydrous zinc chloride: 5-15 parts, co-solvent : 1-10 parts, water: 20-40 parts. The components of the composite antiscaling and corrosion inhibiting agent of the present invention have a good synergistic effect, so that the compounding agent has excellent scale and corrosion inhibiting properties. The calcium ion tolerance is high, and the scale inhibition rate can reach 98% according to the standard measurement. It is especially suitable for industrial circulating water with a water temperature of 50°C-60°C. It has excellent scale and corrosion inhibition performance when used in circulating cooling water systems with high concentration, high temperature, and high alkalinity.

Description

technical field [0001] The invention relates to a compound scale and corrosion inhibitor, in particular to a green and environment-friendly compound scale and corrosion inhibitor and a preparation method thereof. Background technique [0002] Industrial cooling water accounts for a considerable proportion of my country's industrial water. With the continuous growth of the economy, the contradiction between supply and demand of existing water resources has become more prominent. In order to save water and reduce energy consumption, it is necessary to continuously increase the concentration of circulating water. The Ministry of Science and Technology " During the Tenth Five-Year Plan period, it focused on supporting the project of "development and application demonstration of industrial circulating cooling water water-saving technology", and encouraged the concentration of industrial circulating cooling water to increase to more than 5 times, which played an important role in sa...
