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 needs to be rust-removed and anti-rust, which not only prolongs the process, increases production costs, but also easily produces secondary pollution and increases energy consumption.
[0003] In addition, the current environment-friendly 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, such as the invention with the patent publication number CN102586788 Provided are a cleaning antirust agent and a preparation method thereof, and a technical scheme for using the cleaning antirust agent to remove scale and prevent rust. The cleaning antirust agent mainly consists of citric acid, ethylenediaminetetraacetic acid salt, ammonium nitrate, It is composed of scale inhibitor dispersant, penetrant, corrosion inhibitor, solubilizer and deionized water. Because ammonium nitrate is used in the preparation process of this invention, it will obviously bring certain safety to customers in the production and use links. Hidden danger

Abstract

The invention provides an environment-friendly rustproof cleaning agent prepared from the following raw materials in percentage by weight: 2-5% of one or mixture of multiple of phosphoric acid or phosphate, 2-5% of one or mixture of multiple of boric acid or borate, 0-5% of strong base, 0.5-1% of anionic surface active agent, 0.5-1% of nonionic surface active agent, 0.5-1% of one or more than one of edetic acid or ethylenediamine tetraacetates and the balance of water. According to the invention, the raw materials are added into water in sequence to obtain the rustproof cleaning agent. The environment-friendly rustproof cleaning agent provided by the invention is safe and environment-friendly and has good dustproof cleaning capability.

Description

technical field [0001] The invention provides a cleaning agent, which is an environment-friendly anti-rust cleaning agent especially suitable for cleaning metal.
