Abstract
The invention relates to the technical field of soldering flux used for the electronic industry, is an improvement on the existing technology and particularly relates to an activating agent used for water-based soldering flux. The activating agent comprises, by weight percent, 70.0%-95.0% of organic acid and 5.0%-30.0% of an oil-soluble film forming agent. Compared with the prior art, the activating agent has the beneficial effects that the activating agent is the activating agent obtained through pretreatment, the activating agent is added into the water-based soldering flux, corrosion of the water-based soldering flux on a printed circuit board and welding equipment can be obviously reduced, and the corrosion problem of the water-based soldering flux is solved.
Description
Technical field
The present invention relates to used in electronic industry scaling powder technical field, is improvements over the prior art, and in particular to Yi Zhongshui
Based scaling powder activator.
Background technology
Scaling powder is one of very important material in electronics industry, and current scaling powder is mainly with alcohols solvent
Composition that is main, being prepared from by organic cosolvent, addition activator, surfactant, rosin resin and other auxiliary agents.It is many
Well known, alcohols solvent and organic cosolvent are all combustible materials, the easy initiation fire during transport, storage and use,
Bring potential safety hazard;Additionally, alcohols solvent and organic cosolvent are used as VOC, gas can be produced and dissipated low
In atmosphere, photochemical fog is formed, direct damaging effect is produced to human body and air pollution is caused.For this purpose, one kind with
Deionized water is arisen at the historic moment for the water-based scaling powder of main component, and it is by adding in deionized water activator, surface-active
Agent and other auxiliary agents etc. are constituted, and it not only can effectively realize that electronic product is welded, and will not be to environment and operating personnel
Directly harm is caused, is the main product of following scaling powder.But, it is not steady enough also to there is electric property in current water-based scaling powder
The problems such as fixed, organic acid for activating agent produces strong corrosion to printed circuit board and welding equipment, hinders the big of water-based scaling powder
Sizable application.
