Abstract

The invention relates to the technical field of cleaning agents, and specifically discloses a green and environment-friendly neutral water-based cleaning agent as well as its preparation method and application. The cleaning agent includes the following components in mass percentage: surfactant 3%-10%; oil-soluble solvent 10%-20%; builder 2%-8%; defoamer 0.1%-0.5%; deionized water 65%‑80%. The raw materials of the present invention are all neutral products with mild performance, and the cleaning agent produced has light smell, no halogen, no flash point, no corrosion of materials, no phosphorus and environmental protection, no influence on the cleaned components, and good material compatibility , non-flammable, non-explosive, safe to use, strong cleaning power, and the solder joints of parts after cleaning remain bright, etc., suitable for PCB cleaning.

Description

technical field [0001] The invention relates to the technical field of cleaning agents, in particular to a green and environment-friendly neutral water-based cleaning agent and its preparation method and application. Background technique [0002] In recent years, major changes have taken place in the field of electronic assembly technology, such as the miniaturization of components, the high density of component mounting and structure, etc. At the same time, the improvement of solder paste formula makes the residual flux residue on the printed circuit board (PCB) Cleaning of objects is becoming more and more difficult. [0003] Traditional solvent-based cleaning agents have been gradually phased out due to the existence of certain fire safety hazards and the great damage to the environment and human body. At present, the popular PCB water-based cleaning agents on the market are mainly strong alkaline cleaning agents. This type of cleaning agent has a strong decontamination ...
