Abstract

The invention relates to the technical field of environment-friendly materials, in particular to an environment-friendly scale inhibitor and a manufacture method thereof. The environment-friendly scale inhibitor is manufactured with polyepoxysuccinic acid, 1-hydroxyethanediphosphonic acid potassium salt, sodium dodecyl sulfate, ethylenediaminetetraacetic acid disodium salt, aluminum potassium sulfate, sodium alginate, polyacrylamide, sodium citrate, sodium pyrophosphate, a dispersant, a hydrochloric acid solution and suitable deionized water. Polyepoxysuccinic acid and 1-hydroxyethanediphosphonic acid potassium salt are used as raw materials and are synergic in terms of scale inhibition; sodium alginate is dissolved in the dispersant; the mixed component A of sodium alginate and the dispersant is mixed with the other materials so that sodium alginate may be dispersed in the scale inhibitor more evenly; the cooperated use of sodium alginate and aluminium potassium sulfate can enhance complexing reaction with metal ions so that scale inhibiting capacity of the scale inhibitor is enhanced; in addition, both polyepoxysuccinic acid and sodium alginate are easily degradable, no environmental pollution is caused, and the environmental protection concept is met.

Description

technical field [0001] The invention relates to the technical field of environment-friendly materials, in particular to an environment-friendly scale inhibitor and a manufacturing method thereof. Background technique [0002] Scale inhibitors are a class of agents that can disperse insoluble inorganic salts in water, prevent or interfere with the precipitation and scaling of insoluble inorganic salts on metal surfaces, and maintain good heat transfer effects for metal equipment. The anti-scaling and anti-scaling agent for cold-exchange equipment is made up of epoxy resin and specific amino resin as base materials, adding appropriate amount of various anti-rust, anti-corrosion and other auxiliary agents, and it is a single component. It has excellent shielding, impermeability, anti-rust properties, good scale inhibition, thermal conductivity, excellent resistance to weak acids, strong alkalis, organic solvents, etc. It has strong adhesion, and the film layer is bright, flexib...
