preparation example Construction

[0027] The invention provides a kind of preparation method of pH-nanometer iron and steel corrosion inhibitor, comprises the following steps:

[0028] (1) prepare palm wax and sodium hydroxide respectively; prepare the mixture of absolute ethanol and deionized water; then prepare the first deionized water;

[0029] (2) Heat and melt the prepared palm wax until clear, and pour it into the first three-neck bottle;

[0030] (3) Pour the prepared sodium hydroxide into the first portion of deionized water until it is completely dissolved, then pour it into the first three-necked bottle filled with liquid palm wax, and finally mix the prepared anhydrous ethanol and deionized water All the mixed solution is poured into the first three-necked bottle;

[0031] (4) the first three-necked bottle in the step (3) is placed in an oil bath, and then three ports of the first three-necked bottle are respectively equipped with a thermometer, an agitator and a reflux condenser, and reacted for ...

Embodiment 1

[0051]Prepare 2000 grams of palm wax and 120 grams of sodium hydroxide, prepare 500 ml of a mixture of absolute ethanol and deionized water with a volume ratio of 1:1, and prepare the first 300 ml of deionized water. Heat and melt the prepared 2000 grams of palm wax at 100°C until clear, then pour it into the first three-necked bottle. Pour 120 grams of sodium hydroxide into the first part of deionized water of 300ml until it is completely dissolved, then slowly pour it into the first three-necked bottle filled with liquid palm wax, and then add the prepared absolute ethanol and deionized water All the mixed solution was poured into the first three-necked bottle. Finally, place the first three-necked flask in an oil bath whose temperature is controlled at 105°C, install a thermometer, a stirrer, and a reflux condenser on the three ports of the first three-necked flask, and react for about 6 hours to obtain a dark red liquid . Prepare 120ml of concentrated sulfuric acid and 5...

Embodiment 2

[0054] Prepare 1600 grams of palm wax and 96 grams of sodium hydroxide, prepare 500 ml of a mixture of absolute ethanol and deionized water with a volume ratio of 1:1, and prepare the first 300 ml of deionized water. The prepared 1600 grams of palm wax is heated and melted at 100°C until clear, and then poured into the first three-necked bottle. Pour 96 grams of sodium hydroxide into the first part of deionized water of 300ml until it is completely dissolved, then slowly pour it into the first three-necked bottle filled with liquid palm wax, then add the prepared absolute ethanol and deionized water All the mixed solution was poured into the first three-necked bottle. Finally, place the first three-necked flask in an oil bath whose temperature is controlled at 106°C, install a thermometer, a stirrer, and a reflux condenser on the three ports of the first three-necked flask, and react for about 6 hours to obtain a dark red liquid . Prepare 96ml of concentrated sulfuric acid a...

Abstract

The present invention provides a kind of preparation method of PH-nanometer iron and steel corrosion inhibitor, comprises the following steps: (1) prepare palm wax, sodium hydroxide respectively; Prepare the mixed solution of dehydrated alcohol and deionized water; Prepare the second One part of deionized water; (2) heat and melt the prepared palm wax until clear, and pour it into the first three-neck bottle; (3) pour the prepared sodium hydroxide into the first part of deionized water until dissolved Completely, then pour into the first three-necked bottle equipped with liquid palm wax, and finally pour the mixed solution of absolute ethanol and deionized water into the first three-necked bottle. The product prepared by the method has stable performance, good physical and chemical properties, long anti-corrosion time, high temperature resistance, thin coating film, guns and cannons do not need to be cleaned before use, and have no adverse effect on the performance of the guns and cannons after shooting.

Description

technical field [0001] The invention relates to iron and steel anticorrosion technology, in particular to a preparation method of a pH-nanometer iron and steel anticorrosion agent, which belongs to the field of organic macromolecule synthesis. Background technique [0002] Anti-corrosion and anti-corrosion of steel equipment and products are very important to maintain stable performance, safety, and prolong life of equipment; in steel equipment and products, anti-corrosion and anti-corrosion of guns and cannons are particularly important. Nowadays, guns and guns are mainly used for anti-corrosion of various oils such as gun oil, butter, etc., as well as various greases. It needs to be washed before use and it is difficult to clean. Smoke is produced when guns and cannons are fired, and coking occurs after shooting, so it is difficult to meet the needs of guns and cannons for sealing. Contents of the invention [0003] The purpose of the embodiments of the present inventi...
