Abstract
A bromine-containing solvent, which has been used as an alternative solvent to a chlorofluorocarbon solvent or a chlorine-containing solvent, is characterized in that it is likely to degrade compared with a chlorofluorocarbon solvent or a chlorine-containing solvent. In the conventional bromine-containing cleaner compositions, the degradation of the compositions are prevented by using a corrosion-protecting agent or a stabilizing agent (e.g., nitroethane). However, when the cleaner compositions are used as cleaners for print circuit boards, the reduction in insulation resistance or leak failure is often caused. Thus, provided is a non-flammable cleaner composition comprising a mixture of a bromide selected from n-propylbromide, methylenebromide, bromochloromethane, n-butylbromide, isobutylbromide, sec-butylbromide and ter-butylbromide as a stabilizer for a bromine-containing solvent and an alkene- or alkyne-type hydrocarbon having 4 to 10 carbon atoms.
Description
Technical field
The present invention relates to the cleaning composition of non-flammable, relate in particular to the non-flammable cleaner composition that in the degreasing of the solder flux washing of printed base plate, electronic unit etc. and electronic unit, structure unit, uses.
Background technology
The printed base plate of paying attention to using in the e-machine of safety, when electronic unit has flux residue at the immersed solder postadhesion; After long-time; This flux residue can moisture absorption, or on flux residue, adhere to impurity, dust etc.; Not only cause the insulativity deterioration between conductor, also can cause producing disadvantageous effects such as corrosion product.Therefore, these printed base plates, electronic unit can wash after immersed solder.
In addition; The parts of accurate instrumentation its make the residual machining oil that adheres to when having in the way in cut, the words of the lubricant that adheres to during in plastic working etc.; With component-assembled behind the accurate apparatus, then become get rusty, sliding coordinates these bad reasons inadequately.Therefore, the parts used of accurate apparatus also will wash after processing.
In the past, in the washing of these electronic units, mechanical part, used washing composition such as the fluorine Lyons can dissolve solder flux or oil well, 1.Yet, fluorine Lyons, 1,1; Washing composition such as 1-trichloroethane can destroy the ozonosphere that surrounds the earth, make a large amount of ultraviolet rays arrive the earth, become the mankind and suffer from skin carcinoma, cataract; Perhaps therefore the reason of the contaminated grade of underground water limits its use in Montreal Protocol in 1988.And then, use gradually than the chlorine series solvents such as methylene dichloride that fluorine Lyons, 1 decompose more easily and the ozone layer destroying coefficient is lower, but these volatile organic solvents decompose generation CO
2, become the former of global warming thereby become gradually and can not use.Like this, owing to can not use fluorine Lyons, 1 etc., recently, new washing composition such as their fluorine Lyons surrogate of a lot of replacements, ethane surrogate have been proposed gradually.
As unrestricted washing composition, also have type aqueous cleanings such as terpene compound that mix use with water, but in the drying of printed base plate; Need to use IPA organic solvents such as (Virahols); Compare with fluorine Lyons 12, methylene dichloride etc., the drying property of the IPA that in the drying of class aqueous cleaning, uses is slower, is easy to generate stain after the washing; Therefore, there is apparent problem.

Summary of the invention
The problem that invention will solve
Patent documentation 1 is in order to solve halogen series solvent and aluminium, reactive magnesium and make the problem of metallic corrosion; Make rust-preventive agent coexistence, but be exactly the rust-preventive agent that mechanical part such as iron and steel is used, therefore as the METALEX itself that Yuka Sangyo K.K. that rust-preventive agent uses makes; Stainless steel for the such automatic immersed solder device of patent documentation 1 keeps the washing of pawl can not have problems; But when being used for the washing of printed base plate, then the insulating resistance value after the washing reduces, can produce leak bad.Though the halogen series solvent is high to the solvability of resinous principles such as rosin; But the detergency to the ionic composition of bioactive agent composition and so on is low, and therefore, patent documentation 2 is inventions of on the basis of patent documentation 1, having added organic solvents such as Virahol; But it does not solve following problems; That is, if rust-preventive agent such as use METALEX, then the insulation resistance of the printed base plate after the washing reduces this problem.This problem was not understood at that time in application but was understood just after application that therefore, the invention of patent documentation 2 did not have petition for examination, but has recalled application.
The cleaning composition of patent documentation 3 is in order to solve that halogen series solvent etch aluminum, magnesium make its corrosive problem and the compsn that added the stablizer that is selected from nitro-paraffin, ether, epoxide, amine; But in the method for the stablizer that has used nitro-paraffins such as previous cited Nitromethane 99Min., nitroethane, nitropropane; Washing composition becomes acidity easily; In patent documentation 3, the also easy step-down of the insulation resistance of the printed base plate after the washing.In addition, the stablizer deficient in stability of nitro-paraffin decomposes easily, if nitro-compound decomposes, then the anticorrosion ability to aluminium, magnesium also reduces.
The problem that the present invention will solve is, existing halogen is that washing composition exists stability problem, if be used for the washing of printed base plate, the reduction of insulation resistance takes place easily then, and it is washing composition that the present invention provides the bromine that solves these problems.
The scheme that is used to deal with problems
Discoveries such as the inventor, the alkene with two keys are hydrocarbon and have bromine that triple-linked alkyne series hydrocarbon produces when the bromine series solvent is decomposed and add in pair keys and the triple bond and have the function of stablizer, thereby have accomplished the present invention.
The present invention is a kind of non-flammable cleaner composition, its comprise be selected from positive propyl bromo, methylene bromide, bromochloromethane, n-butyl bromide, isobutyl bromide, sec.-butyl bromide, the tert.-butyl bromide bromide and, the alkene of carbon number 4～10 is that hydrocarbon and/or alkyne series hydrocarbon mix the mixture that obtains.
Employed bromine series solvent in the cleaning composition, that is, the brominated hydrocarbon after the H in the hydrocarbon is replaced by Br is suitable for the washing of printed base plate.Such brominated hydrocarbon is normally stable, but because it has strong polarity, becomes in the washing composition moisture absorption when containing moisture, and its ionization and reacting with basic metal, earth alkali metal, aluminium etc. makes the alloy corrosion that contains them.Under the situation of printed base plate, owing to used aluminium in the semi-conductor, electrolytic condenser, its and bromine are that cleaning composition reacts and they are corroded.In the present invention; The alkene that is blended in the brominated hydrocarbon is that hydrocarbon and alkyne series hydrocarbon play a role as stablizer; Bromine and two keys that alkene is hydrocarbon, the triple bond generation addition reaction of alkyne series hydrocarbon of the brominated hydrocarbon that ionization is decomposed make the bromine addition, do not produce the corrosive free bromine that can cause aluminium etc.And then because brominated hydrocarbon has the effect of non-fire material, cleaning composition of the present invention has the characteristic of non-flammable.
The effect of invention
Non-flammable cleaner composition of the present invention is the insulating resistance value reduction after a kind of washing that promptly is used in printed base plate can not make washing yet; And can not corrode the high cleaning composition of safety of the alloy of aluminium, magnesium etc.; Owing to have non-flammable, has not the advantage that can treat as the hazardous material in the fire service law.
