Abstract
A scavenger for electronic industry consists of C3-C9 alkane 10-85 wt%, C3-C8 ketone 1-30 wt5, C3-C10 ether 1-30 wt%, C1-C5 alcohol 1-30 wt% and additive 0.01-10 wt%. It contains no fluorochloric alkane and similar matter, and thus has no environmental pollution, and has excellent scavengine capability to rosin, resin, oil dirt and pollutant. It may be used in direct soaking and washing of electronic equipment and PCB, and is supersonic cleaning.
Description
Technical field:
The present invention relates to the clean-out system of electronics, mechanical industry, particularly relate to rosiny leaning solvent on greasy dirt on the objects such as being applicable to clean metal, pottery and the wiring board.
Background technology:
At present; electronics; advancing by leaps and bounds of electrician trade; the soldering that matches is with it also proposed higher requirement with material; simultaneously; the importance of HUMAN HEALTH is also more and more paid attention to by people; advocate and taked a series of measures by developed country; be used to improve the global environment that the mankind depend on for existence; United Nations's Environmental Protection Administration has also proposed the requirement of the material of the harmful atmospheric environment of time limit change; and the electron and electrician industry is because very high to the reliability requirement of portioned product; must after producing welding, clean product; and the clean-out system major part of using now is fluorine-containing; the hydrocarbon compound of chlorine substituent; this type of material has serious destruction to atmospheric ozone layer; belong to necessary time limit that United Nations proposes and forbid the scope of producing and using, this type of material of while hazardness very big to operative employee's healthy same existence is at above factor; the electron and electrician industry presses for to be transformed existing clean-out system, to reach the purpose of protection human health and atmospheric environment.Wherein a measure is exactly the clean-out system that clean-out system is made not contain into the fluorochlorohydrocarbon class.The domestic research institute that how tame clean-out system once occurred, some unit has developed aqueous cleaning agent, " a kind of acidic water-based cleaning agent for metals " of the southern power machine of the notification number announced as Chinese patent 1067275 company, this clean-out system contains carboxylic acid, esters surface active agent and inorganic salts, described carboxylic acid contains 2-7 C, the alkyd of at least one carboxyl and a carboxyl, described esters surface active agent is an alkyl phosphate, described inorganic salt are vitriol, but most of electronic products is avoided and is washed with water, makes that aqueous cleaning agent is promoted aspect PCB and utilization is very restricted.
The organic solvent type clean-out system has appearred again subsequently, the notification number of announcing as Chinese patent is 1045134 Chengdu organic chemistry institutes " a kind of remove the multi-component high-efficient detergent that solder flux is used ", this clean-out system is by Nitromethane 99Min., acetonitrile, ethyl acetate, 1,1,1-trichloroethane, and Virahol or propyl alcohol or ethanol composition, also " 1 of notification number 1078257 U.S. United info stock Co., Ltd that announce just like Chinese patent, 1,2,3, the azeotropic shape composition of 3-pentafluoropropane ", this clean-out system is to contain 1,1,2,3,3-pentafluoropropane and methyl alcohol or ethanol and the composition that contains Nitromethane 99Min..Though the clean-out system of these organic types has stability preferably, and the workpiece that is cleaned is not had corrosion, seepage force is stronger, can remove solder flux and degreasing effectively, toxicity is low, but hydrocarbons still fluorine-containing in clean-out system, chlorine.
Summary of the invention:
The object of the present invention is to provide a kind of syntheticly, the ability of good cleaning rosin, resin, greasy dirt, pollutent is arranged, and it is fast to clean after drying by no fluorochlorohydrocarbon class material; Both can be used to embathe electronic component, can be used for the clean-out system of ultrasonic cleaning again.
Clean-out system of the present invention, composed of the following components by weight percentage

3Alcohol 1-30%
Additive 0.01-10%
Alkane is naphthenic hydrocarbon or straight-chain paraffin, and ketone is naphthenone or straight alkane ketone, and ether is straight chain alkane ether, and alcohol is monohydroxy-alcohol; Additive is the mixture of synergy with nonionogenic tenside, inhibiter, complexing agent.
The preparation method that it is concrete:
1, with 1-2 kind C
3-C
9Alkane 10-90%, 1-2 kind C
3-C
8Ketone 1-30%, C
3-C
10Ether 1-30%, C
1-C
3Alcohol 1-30% joins in the reactor, stirs 30-40 minute, forms mixture.
2, in mixture, slowly splash into additive by weight proportion; After dropwising, restir 10-15 minute, obtain clean-out system of the present invention.
Clean-out system among the present invention does not contain the halohydrocarbon such as freonll-11 that atmospheric ozone layer had destruction, and its hydrocarbons is naphthenic hydrocarbon or straight-chain paraffin, its polarity and C
1-C
5The polarities match of alcohol; be complementary with key in the ethers and the bond polarity in the ketone; has tensio-active agent in the additive; inhibiter, complexing agent; be cleaned that metal object smooth finish is good, not oxidation; being cleaned PCB does not return white; the greasy dirt that is cleaned surfaces such as metal such as copper, aluminium is cleaned; the components and parts of PCB generally all are zinc-plated, and the position of leaking copper is arranged once in a while, also do not corrode owing to generate the copper complex of protectiveness; not patination; rosin that it is surperficial and additive reaction are dissolved in wherein and form the material that is soluble in clean-out system, do not contain to remain in PCB surface whitening look.
