Halogen-free environment-friendly cleaning agent

Abstract

The invention discloses a cleaning agent mainly used for cleaning residues and other oil stains after wave soldering and reflow soldering in the electronic industry. The cleaning agent comprises 80-90 percent by weight of solvent and 5-20 percent by weight of activated additive relative to the percent by weight of the cleaning agent, wherein the solvent comprises one or more of absolute ethanol, isopropanol, normal hexane and cyclohexane; and the activated additive comprises one or more of nonylphenol polyoxyethylene (6) ether, trimethoxy methyl propionate and oleic acid. The cleaning agent does not contain any halogen matter such as trichloroethylene, and the like, can not cause environment problems such as ozone layer depletion, and the like, and basically has no any toxic effect to thehuman body; in addition, compared with the velocity speed and the cleaning capacity of the general trichloroethylene matters, the environment-friendly cleaning agent approaches or completely reaches the velocity speed same as that of the trichloroethylene matters and has remarkable cleaning effect.

Description

technical field [0001] The invention relates to a cleaning agent for cleaning residues and other oil stains after wave soldering and reflow soldering in the electronics industry, especially a cleaning agent that does not contain trichlorethylene, tetrachlorethylene, and does not add any other halogen-containing substances. Substance cleaning agent. Background technique [0002] As electronic products gradually turn to miniaturization, integration, and multi-function, the electronic assembly industry is also developing at a high speed, and the requirements for the safety performance and appearance of assembled products are also getting higher and higher. [0003] After the electronic components are assembled, various pollutants will remain on the circuit, especially the residue formed after welding. If it is not cleaned or cleaned, it will not only affect the appearance of the product, but also affect the long-term reliability of the circuit. cause an impact, and even affect...

Problems solved by technology

[0003] After the electronic components are assembled, various pollutants will remain on the circuit, especially the residue formed after welding. If it is not cleaned or cleaned, it will not only affect the appearance of the product, but also affect the long-term reliability of the circuit. affect, and even affect the electrical performance of the circuit

Usually we use substances such as trichlorethylene or freon to clean the surface of the welded components. Trichlorethylene is an organic solvent-based cleaning agent. Although it has a good cleaning effect, it is highly toxic and extremely damaging to the ozone layer of the atmosphere. Big
