Abstract
The invention discloses a washing agent of a flexible printed circuit board. The washing agent is prepared from the following components in parts by weight: 20 to 80 parts of hexadecafluoroheptane, 10 to 100 parts of nonafluoro butyl methyl ether, 15 to 20 parts of ethanol, 1 to 5 parts of alkane, 1 to 5 parts of fluorine-containing alcohol, 2 to 3 parts of dimethyl dodecyl amine oxide, 1 to 2 parts of modified cocoanut fatty acid diethanolamide, 1 to 2 parts of sodium xylene sulfonate, 2 to 4 parts of nitrilotriacetic acid trisodium salt, 1 to 5 parts of octylphenol (EO) 12-13 ether and 1 to 3 parts of tetrapotassium pyrophosphate. The washing agent provided by the invention is not inflammable, has a rapid volatilization rate, does not contain substances which damage the atmospheric environment, and has a relatively good dissolving performance on dirt of electronic equipment. The washing agent is suitable for washing electronic elements and is particularly suitable for washing application of the electronic elements with residual glue traces and printed circuit boards polluted by flux residues.
Description
Technical field
The present invention relates to a kind of clean-out system, be specifically related to a kind of flexible printed circuit board clean-out system and preparation method thereof.
Background technology
Electronic devices and components need the dirt such as glue trace, welding assisted agent residuals on surface to remove before assembling, some may need manual operation or implement in airtight space when cleaning these materials.It is good that these require not only to need fluorine-containing clean-out system to remain scavenging effect for glue trace and solder flux, and require fluorine-containing clean-out system composition safety and environmental protection, and rate of volatilization is fast, and toxicity is low, and smell is little, nonflammable.
Fluorochemicals is not fire or nonflammable as its major advantage of solvent of fluorine-containing clean-out system, is namely issued to good cleaning performance in nonflammable prerequisite.The most mainly 1 of use in the past, 1,2-Freon 113 (being called for short CFC-113), CFC-113 is as cleaning solvent, there is the advantage such as solubility property, good selectivity, low viscosity, low surface tension, high wetting property, quick-drying of appropriateness, and have do not fire, low toxicity, low corrosion, chemistry and the feature such as thermally-stabilised, so be particularly suitable for the cleaning of the components and parts such as electronics, motor, precision optical machinery, resin treatment and precision optics, and can use as dry solvent.But the ODP value of CFC-113 is 0.8, ODP is the index characterization of ozone depletion potential, and ODP numerical value is higher, represents larger to the destructiveness of ozone.So this also just illustrates that the ozonosphere of CFC-113 to atmospheric advection layer has destroying infection.So developed country prohibits the use on January 1st, 1996 it, China has also eliminated the use of CFC-113 completely in 2006.
Summary of the invention
The object of this invention is to provide a kind of flexible printed circuit board clean-out system and preparation method thereof, this clean-out system is nonflammable, rate of volatilization is fast, not containing the material destroying atmospheric environment, to electronics dirt, there is good solubility property.Be applicable to the cleaning of electronic component, the Cleaning application of the printed circuit board (PCB) especially having the electronic component of removing residual glue trace and film of flux residue to pollute.
Object of the present invention can be achieved through the following technical solutions:
A kind of flexible printed circuit board clean-out system, count by weight, raw material is composed as follows: ten hexafluoro heptane 20-80 parts, nine fluorine butyl methyl ether 10-100 parts, ethanol 15-20 part, alkane 1-5 part and fluorine-containing alcohol 1-5 part, dimethyl dodecyl amine oxide 2-3 part, modification cocoanut fatty acid diethanolamide 1-2 part, sodium xylene sulfonate 1-2 part, nitrilotriacetic acid trisodium salt 2-4 part, octyl phenol (EO) 12-13 ether 1-5 part, tetrapotassium pyrophosphate 1-3 part.
Preferably, a kind of flexible printed circuit board clean-out system, count by weight, raw material is composed as follows: ten hexafluoro heptane 80 parts, nine fluorine butyl methyl ether 80 parts, ethanol 15 parts, alkane 3 parts and fluorine-containing alcohol 4 parts, dimethyl dodecyl amine oxide 2 parts, modification cocoanut fatty acid diethanolamide 1 part, sodium xylene sulfonate 1 part, nitrilotriacetic acid trisodium salt 2 parts, 2 parts, octyl phenol (EO) 12-13 ether, tetrapotassium pyrophosphate 1 part.
Preferably, described a kind of flexible printed circuit board clean-out system, the carbon atom number of alkane is normal paraffin or the isoparaffin of 5-10.
Preferably, described a kind of flexible printed circuit board clean-out system, alkane is one or more arbitrary combination in Skellysolve A, iso-pentane, normal hexane, isohexane.
Preferably, described a kind of flexible printed circuit board clean-out system, preparation method is as follows: add in encloses container by ten hexafluoro heptane, nine fluorine butyl methyl ethers, ethanol, alkane and fluorine-containing alcohol, 30min-60min is mixed at normal temperatures under normal pressure, then dimethyl dodecyl amine oxide, modification cocoanut fatty acid diethanolamide, sodium xylene sulfonate, nitrilotriacetic acid trisodium salt, octyl phenol (EO) 12-13 ether, tetrapotassium pyrophosphate is added, mix 15min-30min under normal pressure at normal temperatures, finally obtain required rinse product.
Beneficial effect of the present invention: the fluorine-containing clean-out system of the present invention, under the prerequisite ensureing cleaning capacity, avoid in composition using and can destroy atmospheric ozone layer and Greenhouse effect are high, the long chloride material of not easily degrading of atmospheric lifetime, and the fluorochemicals comprised in composition ensure that it is nonflammable.To electronics dirt, there is good solubility property, mutually solvent simultaneously with material, corrosion-free to metal, glass, pottery, polycarbonate, polyphenylene oxide, nylon, epoxy resin, polyethylene, parameters performance can be equal to the fluorine-containing clean-out system of CFC-113, thus the efficient fluorine-containing clean-out system of obtained environmental protection safety.
