Abstract

The invention discloses a green phosphorus-free anti-scale corrosion inhibitor and relates to the technical field of chemical water treatment. The green phosphorus-free anti-scale corrosion inhibitor is prepared from the following components in percentage by weight: 20 percent to 40 percent of polyamino polyether methylene phosphonates, 5 percent to 10 percent of 2-phosphonio-6-sulfonic acid-1,2-dicarboxylhexane, 5 percent to 10 percent of 2-phosphonobutane-1,2,4-tricarboxylic acid, 10 percent to 20 percent of an acrylic acid/2-methyl-2-acrylamido propane sulfonic acid type polymer, 10 percent to 20 percent of an isopropenyl phosphoric acid and acrylic acid copolymer, 3 percent to 8 percent of ZnSO4.7H2O, 0.5 percent to 1.5 percent of sodium molybdate and the balance of water. The green phosphorus-free anti-scale corrosion inhibitor has stable properties, is easy to store and has an excellent anti-scale corrosion inhibition performance; the green phosphorus-free anti-scale corrosion inhibitor is simple and convenient to treat at a later period and has no harms to the environment.

Description

A kind of green non-phosphorus scale and corrosion inhibitor
Technical field：
The present invention relates to chemical industry water-treatment technology field, and in particular to suitable for high concentration multiple A kind of green non-phosphorus scale and corrosion inhibitor.
Background technology：
At present the cycles of concentration of domestic cycle cooling water is mostly 3-4 times, in high rigidity, high-alkali Under degree, the harsh conditions of high Ph, accessible cycles of concentration is lower.
The content of the invention：
Present invention aims to the defect and deficiency of prior art, there is provided a kind of green nothing Phosphorus anti-incrustation corrosion inhibitor.
In order to solve the problems of background technology, a kind of recirculating cooling water system of the present invention Non-phosphorus scale and corrosion inhibitor, its components by weight is：Multiple-β transistor： 20%-40%, 2- phosphino- -6- sulfonic acid -1,2- dicarboxylic acids hexanes：5-10%, 2- phosphonobutane - 1,2,4- tricarboxylic acids：5-10%, acrylic acid/2- methyl -2- acrylic acid amido propane sulfonic acid classes Polymer：10-20%, isopropenylphosphonic acid and acrylic copolymer：10-20%, ZnSO4·7H2O： 3-8%, sodium molybdate：0.5-1.5%, water：Surplus.
The present invention has the beneficial effect that：With stable speciality, easily storage, excellent scale inhibitor Performance, the later stage processes easy, and environmental sound.
