Abstract
The invention discloses a preparation method of an antirust glycerol. The antirust glycerol is prepared from the following components in percentage by weight: 0.1-0.5% of sodium molybdate, 0.1-0.4% of zinc borate, 0.1-0.3% of furfural, 0.1-0.4% of alkylamino alcohol, 0.1-0.3% of ammonium benzoate, 0.1-0.3% of benzotriazole, 0.1-0.4% of mercaptobenzothiazole, 1-4% of sodium carbonate and the balance of glycerol. The preparation method comprises the following steps: adding sodium carbonate, sodium molybdate and zinc borate into glycerol, heating to 90 DEG C while stirring, adding the other components, stirring, decoloring by adding activated carbon, filtering, cooling and packaging. The antirust glycerol disclosed by the invention is soluble in water or ethanol and insoluble in benzene, chloroform and other organic solvents, has wetting property, can lower the freezing point of water, and is nontoxic; and the antirust glycerol can be used as a corrosion inhibitor for multiple metals, a high / low-temperature-resistant corrosion inhibitor for water paint, an antifreezing fluid and coolant for automobiles and locomotives, an antifreezing lubricant and corrosion inhibitor for instrumentsand meters, and an antiscaling corrosion inhibitor, softening agent and heat conducting agent for cooling water circulation systems.
Description
technical field [0001] The invention relates to a corrosion inhibitor for metal materials, in particular to a method for preparing a corrosion inhibitor compounded with various metal corrosion inhibitors with glycerol (glycerol) as the main component. Background technique [0002] A corrosion inhibitor is a chemical substance or a mixture of several chemical substances that can prevent or slow down the corrosion of metal surfaces when present in the environment (medium) in an appropriate concentration and form. At present, the corrosion inhibitors used by people include inorganic compound corrosion inhibitors and organic compound corrosion inhibitors. Most of the known corrosion inhibitors have a single function, and can only be used to prevent or slow down the corrosion of a single metal, that is, only play a major role in one of the metals such as iron, steel, copper, etc.; its use is single, and it is only suitable for one medium ;In addition, in addition to delaying met...
