Embodiment 1

[0023] A high-flash point electric welding cleaning agent based on absolute ethanol is composed of the following raw materials in parts by weight:

[0024] 12 parts of absolute ethanol; 6 parts of trichlorethylene; 18 parts of triethyl phosphate; 5 parts of stabilizer, wherein the stabilizer consists of polyvinyl alcohol, polyacrylamide and tert-butyl hydroquinone in a mass ratio of 5:2 :3 mixed; 2 parts of saponifier, saponified by triethanolamine and fatty alcohol polyoxyethylene ether mixed according to the mass ratio of 3:2; 52 parts of distilled water.

Embodiment 2

[0026] A high-flash point electric welding cleaning agent based on absolute ethanol is composed of the following raw materials in parts by weight:

[0027] 14 parts of absolute ethanol; 10 parts of trichlorethylene; 21 parts of triethyl phosphate; 6 parts of stabilizer, wherein the stabilizer consists of polyvinyl alcohol, polyacrylamide and tert-butyl hydroquinone in a mass ratio of 5:2 :3 mixed; 3 parts of saponifier, saponified by triethanolamine and fatty alcohol polyoxyethylene ether mixed according to the mass ratio of 3:2; 62 parts of distilled water.

Embodiment 3

[0029] A high-flash point electric welding cleaning agent based on absolute ethanol is composed of the following raw materials in parts by weight:

[0030] 18 parts of absolute ethanol; 14 parts of trichlorethylene; 27 parts of triethyl phosphate; 8 parts of stabilizer, wherein the stabilizer consists of polyvinyl alcohol, polyacrylamide and tert-butyl hydroquinone in a mass ratio of 5:2 :3 mixed; 3 parts of saponifier, saponified by triethanolamine and fatty alcohol polyoxyethylene ether mixed according to the mass ratio of 3:2; 68 parts of distilled water.

[0031] The difference between Comparative Example 1 and Example 2 is that in Comparative Example 1, there are 14 parts of absolute ethanol and 26 parts of triethyl phosphate.

Description

technical field [0001] The invention relates to the technical field of power grid maintenance, in particular to a high-flash point electric welding cleaning agent based on absolute ethanol. Background technique [0002] In the electronic component industry, electronic soldering is an essential process in PCBA, that is, electronic assembly. Flux is often used during soldering. Flux is an important part of solder, which has a great influence on the final electronic soldering performance of products. The use of flux can not only effectively remove oxides or other surface pollution on the surface of the printed circuit board and the solder itself, but also wet the metal surface to be soldered. It can also protect the metal surface from being re-oxidized during soldering and reduce the surface tension of molten solder to promote solder expansion and flow. Electronic components often leave flux residue after soldering. Flux Residue Residues have a significant impact on the app...
