Abstract

Belonging to the field of electronic industry environment-friendly cleaning agents, the invention provides an environment-friendly cleaning agent for electronic industry and a preparation method thereof, and in particular relates to a PCBA cleaning agent for wave soldering post-weld FLUX residue. The environment-friendly cleaning agent is composed of the following raw materials by mass percentage: 41.2%-42.9% of lower alcohol, 51.1%-56.8% of methylsiloxane, 1%-3% of propylene glycol ether, and 1%-3% of limonene. Compared with existing traditional cleaning agents for electronic industry, the electronic environment-friendly cleaning agent provided by the invention does not contain CFC / HCFC or HAP, is friendlier to workers' health in practical use, is safer and more environmentally friendly to the atmospheric environment, and helps enterprises meet EU ROSH, REACH and HF requirements and enhance international competitiveness.

Description

technical field [0001] The invention belongs to the field of environmentally friendly cleaning agents for the electronic industry, and relates to an environmentally friendly cleaning agent for the electronic industry and a preparation method thereof, in particular to a PCBA cleaning agent for residual FLUX after wave soldering and its preparation technology. Background technique [0002] The cleaning agents currently used in the electronics industry contain CFC / HCFC and HAP substances, which not only have a strong pungent odor, but also cause serious corrosion and damage to components, and are extremely harmful to workers' health, destroy the ozone layer of the atmosphere, and pollute water bodies. With the acceleration of the global lead-free process and the implementation of EU ROSH, REACH and HF directives, traditional cleaning agents for the electronics industry cannot meet the existing technical requirements. [0003] For example, the relevant prior art CN104194971A dis...
