Problems solved by technology

[0002] Metal processing parts are often lubricated and cooled with various lubricants during processing. After processing, the workpiece must be cleaned before entering the next process for assembly into finished products, and most cleaning agents wash off the metal surface. When the oil is dirty, the protective layer is destroyed, and the surface is easy to rust, and the subsequent process must be treated with rust removal and anti-rust treatment, which not only prolongs the process, increases production costs, but also increases pollution and energy consumption

Abstract

The invention provides an environment-friendly rust-proof cleaning agent. The environment-friendly rust-proof cleaning agent is characterized by being prepared by adopting raw materials comprising 1 to 99 percent by weight of orange peel extract. The orange peel extract is a multi-component anionic surfactant and a micromolecule oil dissolved cleaning agent, is good in cleaning performance, good in corrosion inhibition performance for ferrous metal and nonferrous metal, capable of being used as the cleaning agent in the environment-friendly rust-proof cleaning agent, capable of forming a layer of protection film on the surface of the metal when used for washing a metal product and capable of preventing the corrosion of the metal and has natural fragrance in the washing process and after the washing.

Description

technical field [0001] The invention belongs to the technical field of metal cleaning and antirust, in particular to a green and environment-friendly antirust cleaning agent. Background technique [0002] Metal processing parts are often lubricated and cooled with various lubricants during processing. After processing, the workpiece must be cleaned before entering the next process for assembly into finished products, and most cleaning agents wash off the metal surface. When the oil is contaminated, the protective layer is destroyed, and the surface is prone to rust, and the subsequent process must be treated with rust removal and anti-rust treatment, which not only prolongs the process, increases production costs, but also increases pollution and energy consumption. [0003] At present, anti-rust cleaning agents that can combine the dual functions of anti-rust and cleaning often add carcinogenic and teratogenic nitrites or nitrates or dichromates. The research on green and e...
