Abstract

The invention provides a preparation method of an industrial machine tool cleaning agent. The cleaning agent is prepared from 3-10% of a sodium salt, 10-20% of ethylene glycol tert-butyl ether, 20-30%of concentrated sulfuric acid, 10-20% of ethylene glycol and the balance of water. According to the invention, after the cleaning agent is used for cleaning, the antirust time of a workpiece is long,is 5-7 days and greatly exceeds the storage time between common procedures, so that the antirust requirement between the procedures is completely met; the cleaning agent and the method for cleaning the workpieces are suitable for cleaning the workpieces in the fields of automobile parts, engineering machinery, agricultural machinery and the like, and particularly have obvious advantages when theworkpieces are iron castings or cold-rolled sheet workpieces.

Description

technical field [0001] The invention belongs to the technical field of cleaning agent preparation, and in particular relates to a preparation method of an industrial machine tool cleaning agent. Background technique [0002] In the process of machining and manufacturing, the workpiece is often contaminated with various oil stains, and the existence of oil stains seriously affects the operation of the next process, such as electric welding, electroplating, etc. Therefore, degreasing is the basis for the next treatment. After cleaning with cleaning agents that are commonly used now, the workpieces are prone to rust and the storage time is short, especially cast iron and cold-rolled plate workpieces. Therefore, ordinary cleaning agents are not suitable for long-term storage between processes and humid conditions in the storage workshop. Moreover, ordinary cleaning agents are very alkaline and are not suitable for manual cleaning. Therefore, we have developed this cleaning ag...
