Problems solved by technology

In chemical derusting, the dipping derusting method is now used in China. When this method is used, it is first necessary to build a huge immersion tank, and the construction investment is very large; secondly, the hydrogen released during the derusting process is easy to cause rust on the metal surface Hydrogen embrittlement, affecting organic properties
In addition, there is a more serious problem of waste liquid treatment when changing the bath liquid.
The construction cost of the huge waste liquid treatment plant and the high daily consumption of waste liquid treatment facilities are the Achilles heel of this rust removal method

Abstract

The invention discloses a self-stripping type metal rust remover. The self-stripping type metal rust remover consists of the following raw materials in parts by weight: 15-18 parts of n-ethyl maleimide, 15-16 parts of succinimide, 13-14 parts of phthalimide, 12-15 parts of maleimide, 13-16 parts of fumaric acid, 15-18 parts of phthalic anhydride, 18-20 parts of methylhexahydrophthalic anhydride, 15-18 parts of methacrylamide, 13-15 parts of methyl nadic anhydride, 16-18 parts of dimethylacetamide, 13-15 parts of acrylamide, 5-6 parts of methyl methacrylate, 3-4 parts of styrene, 5-6 parts of hydroxyethyl acrylate, 6-8 parts of sodium polyacrylate, 5-6 parts of sodium polymethacrylate, 3-5 parts of lauroamide propyl betaine, 75-80 parts of deionized water and the like. After the self-stripping type metal rust remover is applied to the rust surface of the metal, the rust remover is used for enabling the metal rust to be made into solid flake-shaped substances and automatically stripping the solid flake-shaped substances; the self-stripping type metal rust remover is not required to be dipped in a tank during constructing; the self-stripping type metal rust remover can be applied in a spray coating manner, also can be applied in a brush coating manner and is suitable for a variety of industries for a variety of purposes.

Description

technical field [0001] The invention relates to the technical field of a rust remover, in particular to a self-stripping metal rust remover. Background technique [0002] At present, the weight of metal equipment and materials scrapped due to corrosion every year in the world is about 100 million tons or more, so metal anticorrosion is an important task for human beings. Before people adopt various anti-corrosion measures on various metal products, the process of rust removal is almost always indispensable. The current rust removal methods mainly include mechanical rust removal and chemical rust removal, with the latter being the main method. In chemical derusting, the dipping derusting method is now used in China. When this method is used, it is first necessary to build a huge immersion tank, and the construction investment is very large; secondly, the hydrogen released during the derusting process is easy to cause rust on the metal surface Hydrogen embrittlement, affecti...
