Description
The present invention relates to the cleansing composition and the purging method of semi-conductor or metal, liquid crystal cleaning usefulness, be specifically related to the used in electronic industry aqueous cleaning agent.
Hard disc of computer parts such as hard disk drive suspension mechanism and disk drive element HGA, matrix all is stainless material, in the course of processing, various impurity can be stain in its surface, and the liquid dirt is arranged, as the lubricating oil that uses in the processing; The solid dirt is also arranged,, in transmission course, also can stain finger mark simultaneously as dust, abrasive material, metal oxide and carbon deposit etc.These dirts generally all are to be adsorbed on the metallic surface by electrostatic attraction and Van der Waals force.For the liquid dirt, generally be on the metallic surface, to adhere to into the thin even or uneven oil lamella of one deck, and the solid dirt, typically refer to the very little discrete particles of three-dimensional space, they are rare on more uniform and bigger region surface in the adhesion of metallic surface, and often only contact and adhere to the surface on some less points.Because dirt difference, its scavenging mechanism are also different, generally are that the solid dirt is removed than liquid dirt difficulty.
Fluorine Lyons (being CFC) is the fluorochlorohydrocarbon kind solvent, because it is good that it has chemical stability, toxicity is little, do not burn, and surface tension is less, does not damage to be cleaned material and can to keep many advantageous characteristic such as strong perviousness, rapid-drying properties, is widely used as the refrigeration agent of air-cooling system, refrigerator etc. so far, the propellant of atomizer, the clean-out system of the whipping agent of lagging materials such as urethane foam and film, audiotape, electrical equipment, electronic component, precision optical machinery etc.But the ozonosphere in these material havoc earth high-altitudes, the harm humans ecotope, so fluorine Lyons 11, fluorine Lyons 12, fluorine Lyons 113, fluorine Lyons 114, fluorine Lyons 115 and the mixture that contains them all are the materials of time limit production in the world and use.In recent years, also developed some short-term surrogates, as Hydrochlorofluorocarbons (HCFC), perfluoroparaffin (PFC) and other halogenated solvents etc.HCFC is that the part halogen atom in fluorine Lyons is replaced by hydrogen atom, makes the ozone-depleting of CFC value (ODP value) reduction of diving, but it still can damage the ozone layer, and also will be eliminated to the year two thousand twenty, is no more than the year two thousand forty the latest.Some organic solvent also can be used as the surrogate of CFC, but cleaning performance is good not as the CFC cleaning performance, and flash-point is low, inflammable, explosive, and some is also toxic simultaneously, and operating environment is had relatively high expectations.Therefore people's expectation develop can substitute CFC high performance non-halogen be clean-out system, but do not have such clean-out system openly to report up to now as yet with excellent cleaning performance.
The objective of the invention is to overcome the shortcoming of prior art, a kind of nontoxic non-corrosiveness is provided, the cleaning hard disc of computer parts of readily biodegradable or the aqueous cleaning agent composite of liquid crystal.
Cleansing composition of the present invention basic composition is:
Weight percentages (%)
A. polyoxyethylenated alcohol sodium sulfate 5-10
B. polyoxyethylene nonylphenol ether 10-20
C. coconut oleoyl diethanolamine or 10-15
The alkylol amide phosphoric acid ester
D. ethylene glycol alkyl oxide 1-10
E. straight or branched alkyl alcohol 5-10
F. contain nitronic acid or hydroxycarboxylic acid complexing agent 0.1-0.2
G. polyethers GP 1-4
H. deionized water surplus
The complexing agent F that the present invention uses is organic chelate and agent, as ethylenediamine tetraacetic acid (EDTA) (EDTA) and sodium salt, Trisodium Citrate etc.
Described ethylene glycol alkyl oxide D can be an alkyl oxide, also can be dialkyl ether, can be ethyl, propyl group or butyl ether.
Straight or branched alkyl alcohol E of the present invention is side chain or straight chain low-grade alkane alcohol, as the mixing of ethanol, propyl alcohol, Virahol, butanols or its arbitrary proportion.
Described polyethers GP is a colourless transparent liquid, and molecular-weight average is 1000-2000.
The anti-soil dirt that 0.5-1.5% also can be arranged in the above-mentioned cleansing composition is deposition agent I again, and as Xylo-Mucine (CMC), polyvinyl alcohol or polyvinylpyrrolidone (PVP), the dirt under preventing to come off is again attached on the surface that cleans up.
In all raw materials, polyoxyethylenated alcohol sodium sulfate and polyoxyethylene nonylphenol ether are colourless to light yellow transparent liquid, coconut oleoyl diethanolamine or alkylol amide phosphoric acid ester are the reddish-brown transparent liquid, these tensio-active agents are water-soluble fully, do not fire, not quick-fried, readily biodegradable is the main component of clean-out system.The complexing agent that the present invention uses is organic chelate and agent, as ethylenediamine tetraacetic acid (EDTA) (EDTA) and sodium salt thereof, Trisodium Citrate, is white particle or Powdered, except can chelating Ca
2+, Mg
2+Outward, can also chelating Fe
3+, Cu
2+Etc. many other metal ions, thereby prevent the consumption of tensio-active agent, also overcome the overfertilization phenomenon of using the deterioration water quality that the phosphoric acid salt inorganic assistant agent causes simultaneously, environment is not produced pollution.Described ethylene glycol alkyl oxide can be an alkyl oxide, also can be dialkyl ether, can be ethyl, propyl group or butyl ether, is colourless transparent liquid, and dirts such as mineral oil, grease are had stronger dissolving power.Alkyl alcohol is generally side chain or straight chain low-grade alkane alcohol, as ethanol, propyl alcohol, Virahol, butanols etc., is colourless transparent liquid, can dissolve dirt, also can regulate the viscosity of clean-out system.Described polyethers GP is a colourless transparent liquid, molecular-weight average is 1000-2000, the froth breaking effect is arranged, too many as foam in the clean-out system, often bring difficulty to rinsing, waste time and energy and waste a large amount of water, therefore adding some nonionogenic tensides such as polyethers has the effect of the foamy of inhibition, makes that being cleaned parts is easy to flushing.
With above-mentioned raw materials heating for dissolving under 40-60 ℃ of temperature, add above-mentioned each component one by one, make its whole dissolvings, can obtain the light yellow liquid of homogeneous transparent, can be mixed with arbitrary proportion with water, and nontoxic, non-corrosiveness, free from environmental pollution, its key technical indexes is:
