Abstract

The invention belongs to the field of chemical cleaning agents, discloses a water-soluble cleaning liquid used for magnesium alloy cleaning and further discloses a preparation method of the water-soluble cleaning liquid. The water-soluble cleaning liquid comprises, by weight, 8-20 parts of non-ionic surfactants, 3-10 parts of corrosion inhibitors, 2-8 parts of anionic surfactants, 2-4 parts of pHregulators, 2-5 parts of chelating agents and 60-80 parts of water. A magnesium alloy cleaning agent is good in emulsibility, high in deoiling ability, stable in performance, good in cleaning performance and high in rust prevention ability and has the excellent anti-corrosion ability to a magnesium alloy.

Description

technical field [0001] The invention belongs to the field of chemical cleaning agents, in particular to a water-soluble cleaning solution for magnesium alloy cleaning and a preparation method thereof. Background technique [0002] With the continuous advancement of modern processing technology and material technology, people have a soft spot for lighter and stronger materials, so people's demand for magnesium alloy materials has become stronger and stronger in recent years. Although magnesium alloy materials have excellent properties, because magnesium metal is a very active metal, it can burn at room temperature, which makes its processing difficult. [0003] Cleaning is an important step in the metalworking process. Magnesium alloy cleaners often have the following problems: 1. The product concentration is too high, the product is unstable and easy to delaminate; 2. The product has a short service life and is not durable; 3. It is easy to cause corrosion to the substrate;...
