Abstract

The invention discloses a protective agent for a water circulation system, and a preparation method thereof. The protective agent for the water circulation system comprises the following raw materialcomponents: 8-12 parts of gluconic acid, 15-25 parts of HEDP synthetic agents, 8-12 parts of poly-aspartic acid, 3-7 parts of adipic acid, 8-12 parts of sodium caprylate, 10-20 parts of triethanolamine, 25-35 parts of deionized water and 5-7 parts of monoethanolamine. The protective agent has the beneficial effects that a firm and elastic protective film is formed on a metal surface, and used forisolating water from the metal surface; damage to the metal surface by water flow is avoided; the protective agent has the advantages of long life, resistance to acid and alkali, extremely high resistance to high temperature, a certain repair function for the metal surface damage and excellent osmosis prevention, and the airtightness of a water system is improved; slight leakage of equipment and pipelines is avoided; the protective agent has the high hard water resistance, and calcium and magnesium in water can be decomposed quickly; the protective agent can be chelated with various metals, and no scaling is generated; and the water quality remains stable.

Description

technical field [0001] The invention relates to the technical field of chemical corrosion and electrochemical corrosion protection, in particular to a water circulation system protective agent and a preparation process thereof. Background technique [0002] Metal materials are damaged by the action of the surrounding medium, which is called metal corrosion. Metal rusting is the most common form of corrosion. During corrosion, a chemical or electrochemical heterogeneous reaction occurs at the interface of the metal, turning the metal into an oxidized (ion) state. This will significantly reduce the mechanical properties of metal materials such as strength, plasticity, and toughness, destroy the geometry of metal components, increase wear between parts, deteriorate electrical and optical physical properties, shorten the service life of equipment, and even cause disasters such as fire and explosion. sex accident. The corrosion of metals in natural fresh water can be divided i...
