Anti-rust liquor and processing method therefor

Abstract

The invention relates to antirust fluid. The invention also relates to a processing method of the antirust fluid. The antirust fluid made by the method is provided with obvious antirust function and has light even no pollution to the environment. The antirust fluid is generated mainly from the action of alkcnyl succinic acid and monoethanolamine. The mole ratio of alkcnyl succinic acid to monoethanolamine is 0.5-1 to 1. The main components of the antirust fluid are alkcnyl succinic acid dodecenylbutadioic, water and monoethanolamine.

Description

(1) Technical field [0001] The invention relates to the field of antirust technology, in particular to an antirust liquid and a processing method thereof. (2) Background technology [0002] At present, in the processing of domestic mechanical product parts and components, sodium nitrite aqueous solution is generally used for anti-rust treatment between processes. Its advantages are low price, good anti-rust effect on ferrous metals, and easy to use. However, sodium nitrite is toxic and carcinogenic, and when the surface water of the workpiece that uses sodium nitrite to prevent rust evaporates, there will be hard solid sodium nitrite on the surface, which will affect the processing quality of the next process. In China, new water-soluble corrosion-inhibiting materials are extensively developed to replace sodium nitrite. In the industry, such as triethanolamine hydroxyethyl cellulose and sodium nitrite are used in combination to reduce the amount of sodium nitrite used, espec...

Problems solved by technology

However, sodium nitrite is toxic and carcinogenic, and when the surface water of the workpiece that uses sodium nitrite to prevent rust evaporates, there will be hard solid sodium nitrite on the surface, which will affect the processing quality of the next process. In China, new water-soluble corrosion-inhibiting materials are extensively developed to replace sodium nitrite. In the industry, such as triethanolamine hydroxyethyl cellulose and sodium nitrite are used in combination to reduce the amount of sodium nitrite used, especially in grinding and cutting. Emulsion is used, the mineral oil in the emulsion is easy to deteriorate during use, and it is difficult to treat the waste liquid of the emulsion

The parts of mechanical products are sealed with anti-rust oil or anti-rust grease to prevent rust. These anti-rust materials can meet the anti-rust period of 1-2 years, but the parts need to be washed with water before applying anti-rust grease. Then dehydration or gasoline cleaning and drying several processes, which not only consumes energy, but also causes certain pollution to the working environment, and there are certain potential safety hazards.
