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

A kind of water-based scaling powder activator and preparation method thereof
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.
The content of the invention
The purpose of the present invention is to avoid above-mentioned weak point of the prior art and a kind of water-based scaling powder for providing is lived Agent.Water-based scaling powder activator of the present invention is pretreated activator, in being added to water-based scaling powder, can be significantly Water-based scaling powder is reduced to printed circuit board and the corrosivity of welding equipment, the corrosion problems of water-based scaling powder are solved.This Invention is practical, and market application foreground is wide.
The purpose of the present invention can be realized by following measure:
A kind of water-based scaling powder activator of the present invention, its ingredient percentage by weight(%)For:
Organic acid 70.0 ~ 95.0%,
Oil-soluble film forming agent 5.0 ~ 30.0%,
Each Ingredients Weight sum is 100%.
Described organic acid be 2 hydroxy propanoic acid, levo form 3- hydracrylic acids, glutaric acid, hydroxyacetic acid, citric acid, D- β- Hydroxy-iso-butyric acid, 3- methyl -3, one kind in 5- dihydroxy-acids, positive valeric acid, DL- pantonines-hydroxypentanoic acid, fluoboric acid or It is several.While its Main Function is that the oxide on surface by weldering mother metal and solder is removed in welding process, work is significantly reduced Corrosiveness of the agent to printed circuit board, solves the problems, such as that organic acid for activating agent produces strong corrosion to printed circuit board.
Described oil-soluble film forming agent is by acrylic resin film forming agent, polyvinyl alcohol, polyvinylpyrrolidone, silica acrylic acid One or more in ester.Its Main Function is for wrapping up organic acid.
A kind of preparation method of water-based scaling powder activator of the present invention, comprises the steps:(1)Weigh 70.0 ~ 95.0% Organic acid is added in reactor, and adds the distilled water of 2 times of activating agent weight;(2)Be heated to 50 ± 5 DEG C stirring (1 ± 0.5) h, speed of agitator is 200 ~ 1000r/min;5.0 ~ 30.0% oil-soluble film forming agents are subsequently adding, are rapidly heated to (90 ± 5) DEG C stirring (5 ± 1) h, speed of agitator be 500 ~ 1000r/min;(3)Water-cooled quick stirring simultaneously;(4)Drying, grinding are obtained final product A kind of described water-based scaling powder activator.
The present invention has the advantage that compared to existing technology:Water-based scaling powder activator of the present invention is pretreated work Agent, in being added to water-based scaling powder, can significantly reduce corrosion of the water-based scaling powder to printed circuit board and welding equipment Property, solve the corrosion problems of water-based scaling powder.Of the invention practical, market application foreground is wide.
