Abstract

The invention discloses environmentally-friendly cleaning-free water-based scaling powder. The powder at least includes a mixture composed of one or more of OP-10-polyethylene glycol octylphenol ether, cetyl trimethyl ammonium bromide, dioctyl sodium sulfosuccinate, fatty acid methyl ester sulfonate, succinic acid, adipic acid, DL-malic acid, dibromo butene diol, citric acid, glutaric acid, dimethylamine hydrochloride, polyethylene glycol 400, propylene glycol monomethyl ether, glycolic acid and absolute ethyl alcohol and the balance pure water. In this way, in order to solve the problems existing in the prior art, the environmentally-friendly cleaning-free water-based scaling powder can substitute traditional solvents and does not need to be heated before usage, and the problem that traditional scaling powder is likely to get explosive and flammable is effectively solved; moreover, surface tension of water and tin is greatly reduced, the quality of processing technologies including electronic installation and connection, tin coating on copper strips, reflow soldering and the like is improved, and the scaling powder has the advantages of being long in preservation time, stable andsafe in property, adaptive to a severe cold environment, environmentally friendly, free of pollution and the like.

Description

technical field [0001] The invention relates to the field of chemical industry, in particular to an environment-friendly no-cleaning water-based flux. Background technique [0002] The main components of traditional soldering flux are rosin, methanol, ethanol, etc., which volatilize into the air to form photochemical smog, which causes great pollution to the environment. At the same time, a large amount of residue is produced during production, which is not easy to clean. In particular, due to poor stability, it needs to be heated before use, and there is a risk of explosion. Contents of the invention [0003] The main technical problem to be solved by the present invention is to provide an environmentally friendly no-cleaning water-based flux, which can replace traditional solvents for the problems existing in the prior art, without heating before use, effectively solving the problem of flammability and explosion of traditional fluxes, and extremely Greatly reduce the su...
