Description
Technical field
The present invention relates to a kind of electronic component cleaning agent and preparation method, belong to sanitising agent technical field.
Background technology
Along with the fast development of world's electronics and information industry, the electronic component industry development as electronics and information industry basis is also rapidly abnormal.Electronic component is just entering the components and parts epoch of new generation based on new electronic component, it will replace traditional components and parts substantially, electronic devices and components require to be main improvement by original the miniaturization for adaptation complete machine and novel process thereof, become to meet digital technique, to develop the characteristic requirements proposed be master to microelectronics, and be the complete satisfied industrialized development stage.Electronic component is the basis of composition electronic product, and it is study that the kind of the electronic component that understanding is conventional, properity also can correctly be selected, grasp the basic of electronic technology.Conventional electronic component has: resistance, electric capacity, inductance, potentiometer, transformer, triode, diode, IC etc., with regard to mounting means, can be divided into conventional mounting (also known as through hole dress and DIP) and the large class of surface mounting two at present.
Clean-out system solvent is a very large category, of a great variety, comprises inorganic cleaning and the large class of organic washing two.Briefly, organic clear numerous agent is exactly the clean-out system made containing carbon compound, and inorganic clear numerous agent is exactly the clean-out system that carbon-free compound is made, and therefore they belong to inorganics in the difference of organic washing agent and inorganic clean-out system.
Water is most important clean-out system, has the irreplaceable function and position of other any clean-out system.Common water is easy to obtain from occurring in nature, and water has very strong solvency power and dispersion force.But the surface tension of water is large, in use need to add tensio-active agent, to reduce surface tension, increase surface moist.In general industry cleaning, acid, the proportioning of alkali and water is more common, and some metal washes with water and will add rust-preventive agent.Aq. type clean-out system is mixed with by tensio-active agent (as sodium alkyl benzene sulfonate, sodium alkyl sulfate) and various auxiliary agent (as tripoly phosphate sodium STPP), auxiliary, during dirt on washes surface, the surface tension of the aqueous solution can be reduced, improve the material of clean effect.Solid detergent, liquid washing agent is divided into by product appearance form.Solid detergent output is maximum, claims washing powder traditionally, comprises finely powdered, particulate state and hollow bead shape etc.Also have between detergent paste therebetween, also claim washing cream.All kinds of synthetic detergent has different production technique, wherein complicated with solid detergent.Countries in the world generally produce hollow bead shape solid detergent, adopt high tower spray drying method, and its master operation has Pulp preparation, spraying dry, wind to send aging and packaging.Liquid washing agent manufactures easy, only need by tensio-active agent, auxiliary agent and other additives, and treated water, sends into mixing machine and carries out mixing.
Half aq. type clean-out system is also accurate aq. type clean-out system, forms as alcohols, organic hydrocarbon etc. by high boiling solvent and promoting agent etc.Usually containing 5% one 20% moisture, generally nonflammable, but heat cleaning time water-content control improper, may combustion phenomena be produced.Half aq. type cleaning has washed with solvent that some are different, and its Cleaning principle peels off to remove, instead of dissolving.In order to prevent the greasy dirt peeled off to be attached in cleaned material, scavenging solution will circulate continuously, and increases water-and-oil separator again.Partly wash usual cleaning performance fine, but running cost is higher, waste liquid can not regenerate recovery, reuses, containing COD(chemical oxygen demand) higher, need to carry out wastewater treatment.Half aq. type clean-out system adsorbs the novel detergent product of the medicament that various auxiliary agent synthesizes by fine particulate weakly alkaline, the active abrasive particle of natural interface is adopted to be raw material, coordinating multiple actives and sterilant, rumbling compound, that the green technology such as agent and unique bright factor high-tech is seen through in import is formulated, is a kind of multi-functional, efficient comprehensive Environment protection cleaning care products.Be the decontamination product of Modern New, clean effect is unique, and purposes is wide, is free from side effects to human body skin.By active abrasive particle be help with abrasive particle in pollute containing all kinds of serious tough stains more thoroughly can be removed fast with slight soft friction during unique cleaning agent matching purge.The dirt such as black dirt, heavy oil dirt, cement scale, spackling dirt, coin marking, rust deposite, gluing matter, tea stain, drink stain, glue hammering, leather shoes scratch, obstinate wax stain, aluminium trace, wooden trace, grid trace, watermark, footwear print, ink print, environmental protection, do not damage brick face, do not hinder hand.
Leaning solvent refers to water-fast organic solvent.Leaning solvent is made up of varsol, halogenated hydrocarbon solvent, alcoholic solvent, ether solvent, ketones solvent, esters solvent, phenol solvent, mixed solvent.
The clean-out system of electronic component in the market, mostly cleaning performance is bad, and some clean-out systems also have nitrites objectionable impurities, harm environment and people healthy; Because it is higher to the requirement of scavenging solution, there is higher requirement to its corrodibility and cleaning speed, can not should cause damage to electronics again to electronic component Rapid Cleaning.Therefore, develop and a kind ofly novel have environmental hazard low, cleaning performance is excellent, and the clean-out system less to electronic component infringement, has become the problem of those skilled in the art's solution too impatient to wait.
Chinese invention patent specification sheets CN 103555474 A is so a kind of electronic devices and components clean-out system openly.This electronic devices and components clean-out system composition and weight ratio are petroleum hydrocarbon 3 parts, emulsifying agent part, Dipropylene glycol mono-n-butyl Ether 2 parts, 3 parts, 3-methoxyl group-3-methyl isophthalic acid-butanols, 2-aminoethyle alcohol 2 parts, boric acid MEA ester 6 parts, phenylformic acid diethanolamine 5 parts, molybdic acid diethanolamine 1 part, 5 parts, tensio-active agent, water glass 5 parts, thanomin 1 part, ionized water 15 parts.The clean-out system of this invention can remove the residual of tin cream on steel mesh and misprint plate and glue fast, and free from extraneous odour and corrodibility, the danger of not blasting and burning, can not produce steel mesh and wiring board and damage.With the addition of the rust remover such as phenylformic acid diethanolamine or molybdic acid diethanolamine, on the basis of the greasy dirt on clean metal part, can also derusting rust-proofing.But this clean-out system for chip cleaning performance be not fine.
Chinese invention patent specification sheets CN 101368132 A openly so a kind of low-surface tensity circuit chip detergent.This low-surface tensity circuit chip detergent, comprise permeate agent, PH conditioning agent, tensio-active agent, solubilizing agent and pure water, wherein the weight percent of oxygenant is 1% to 5%, the weight percent of PH conditioning agent is 2% to 10%, the weight percent of solubilizing agent is 5% to 10%, the weight percent of tensio-active agent is 1% to 10%, and all the other are pure water; It is alkaline aqueous solution clean-out system, and good to the inhibition of circuit chip surface cleaning tension force, corrodibility is little, not etching apparatus, and not fragile circuit chip is surperficial, is convenient to the treatment and discharge of discarded scavenging solution, meets the requirement of environment protection.But this flocculation agent is not fine for the treatment effect of sewage.But this clean-out system for chip cleaning performance be not fine.
