Object or other external contaminants not only influence product appearance, but also product reliability can be made to be deteriorated, and cause short circuit, corrosion etc.
Cause electric fault.
The cleaning agent of traditional ODS substance containing freon one kind has grease rosin and other resins clear well
Wash effect.But such cleaning agent contains the substance for destroying ozone layer, the in process of production improper use of halogen and its compound
Harm can be brought to staff's body and environment, with the raising of safety and environmental consciousness, ODS is gradually disabled.
Currently used halogen-free cleaning agent is mainly by alcohols, ketone, alkanes, and the low lightning such as lipid is low-boiling
Solvent composition, residue is less after cleaning but its higher cost for such cleaning agent, and toxic, inflammable and explosive, volatility is big, this
Outside, the alcohol of low-carbon class blushing can occur because of the surface that water imbibition is strong and occurs cleaning.
Nowadays the cleaning agent of domestic research and development is various in style, and " water base " bright spot the most can be divided into half water according to the content of water
Based cleaning agent and aqueous cleaning agent, wherein aqueous cleaning agent can also be divided into according to acid-base property alkaline cleaner, neutral cleaners,
Alkaline cleaner.It is able to satisfy cleaning requirement although being substantially all, on the one hand, kind of most of cleaning agents to solder and scaling powder
Class dependence is strong, and clean range is limited, and stability is poor, volatile and to human health.On the other hand, most of cleaning agents
Preparation method is cumbersome, and some need introduces other ancillary equipments, and the complicated component of cleaning agent, and butt welding point can generate corrosion,
A large amount of bubbles can be generated in cleaning process, be not used to full-automatic cleaning and ultrasonic cleaning.
Summary of the invention
The present invention is directed to the above-mentioned deficiency of the prior art, and the purpose of the present invention is to provide a kind of alkalescent composite multifunctions

It closes or four kinds is mixed with the mass ratio for being each greater than 0%；
The aqueous anionic surfactant is: Du Pont's fluorocarbon surfactant 3100, Du Pont's fluorocarbon surfactant 63,
Any one of fluorosurfactant FC-4430 or any two be each greater than 0% mass ratio mixing or three kinds with each
It is mixed from the mass ratio greater than 0%；
The Gemini nonionic surface active agent is by any in Surfynol420, Surfynol440, Surfynol465
Kind or any two be each greater than 0% mass ratio mixing or three kinds be each greater than 0% quality percentage percentage mixing；
The zwitterionic surfactant is: dodecyl alanine, TX-10 phosphate (nonylphenol polyoxyethylene ether phosphorus
Acid esters) any one of or two kinds be each greater than 0% mass fraction mixing.
The corrosion inhibiter is isopropylamine.
The defoaming agent is polyether modified silicon oil.
The aqueous cleaning agent is alkaline species cleaning agent, and PH is 8.0 ~ 9.5.
The nonionic surfactant, Gemini nonionic surface active agent, aqueous anionic surfactant and
