A general flux is a corrosive containing an acidic component in a solvent. For this reason, it is desirable to prevent flux from penetrating or adhering to electrical contact parts of electronic parts such as connectors, switches, volumes, semi-fixed resistors, or parts that do not require soldering of printed circuit boards. is there.

[0003] このため、半田づけに先立って、フラックス這い上がりを防止するための前処理が 行われている。この前処理に用いられるフラックス這い上がり防止剤は、通常、フラッ タスの溶媒に対し撥溶媒性のあるポリマーを含む組成物である。従来、フラックスの 溶媒は典型的に IPAであることから、撥 IPAがフラックス這い上がり防止性能の指標 とされてきた。そのため、フラックス這い上がり防止剤の有効成分として、撥 IPA性能 の高い、ポリフルォロアルキル基含有ポリマーが使用されてきた。  [0003] For this reason, prior to soldering, pre-treatment for preventing flux creeping is performed. The flux creep-up preventing agent used for this pretreatment is usually a composition containing a polymer having a solvent repellency with respect to the solvent of the flatus. Traditionally, the flux solvent is typically IPA, so IPA repellent has been regarded as an indicator of flux creep-up prevention performance. For this reason, a polyfluoroalkyl group-containing polymer having high IPA repellency has been used as an active ingredient of the flux creep-up preventing agent.

発明が解決しょうとする課題  Problems to be solved by the invention
[0007] 近年、半田づけ技術は大きく変化しており、半田づけ部品の小型化の流れもあり、 最近の技術としては、プリント基板の上にクリーム状の半田を印刷し、その上に表面 実装部品を配置し、赤外線や熱風加熱で半田を溶融して半田づけをするリフロー半 田づけが主流になっている。このリフロー半田づけでは、基板ごと半田溶融温度の条 件下にさらされる。し力も、環境への配慮から主流となりつつある鉛フリーの材質の半 田は、溶融温度が従来の鉛半田の溶融温度(183°C)よりも高い傾向にある、たとえ ば約 35°C高いものもある。  [0007] In recent years, soldering technology has changed significantly, and there is a trend toward miniaturization of soldered parts. As a recent technology, cream-like solder is printed on a printed circuit board, and surface mounting is performed thereon. Reflow soldering, in which components are placed and the solder is melted by infrared rays or hot air heating, is the mainstream. In this reflow soldering, the entire board is exposed to the solder melting temperature condition. The solder of lead-free materials, which are becoming mainstream due to environmental considerations, tends to have a melting temperature higher than the melting temperature of conventional lead solder (183 ° C), for example, about 35 ° C higher. There are also things.
[0008] これらから、フラックス這い上がり防止剤にも、半田に応じた特殊な環境下でのフラ ックス這い上がり防止性能が要求されるようになってきている。たとえば、従来のフラッ タス這い上がり防止剤は、上記のようなクリーム半田を使用するリフロー半田づけでは 、充分にその性能を発揮できな 、ことが判明した。  [0008] For these reasons, flux scooping prevention agents are also required to have a flux scooping prevention performance in a special environment corresponding to solder. For example, it has been found that a conventional flattening anti-cracking agent cannot sufficiently exhibit its performance by reflow soldering using cream solder as described above.
[0009] また、部品が小型化しているため、這い上がり防止剤は配線部分に塗布するのは 非常に困難であり、部品全体に適用されることが多い。この際、フラックスの這い上が り防止効果を高めるための撥水撥油性の高い這い上がり防止剤を使用すると、保護 シールの接着等の後加工性に大きな影響を与えてしまうと言う問題もある。 課題を解決するための手段 [0009] Further, since the parts are downsized, it is very difficult to apply the scooping-up preventing agent to the wiring portion, and it is often applied to the whole parts. At this time, there is also a problem that the use of an anti-cracking agent having high water and oil repellency to enhance the effect of preventing the flux from creeping up has a great influence on the post-processability such as adhesion of a protective seal. . Means for solving the problem
[0010] 上記のような諸問題に鑑み、本発明は、最近増えてきている表面実装での半田づ けの使用にお 、て、高 、フラックス這 、上がり防止性能を発揮し得るフラックス這 ヽ 上がり防止組成物を提供することを目的としている。さら〖こは、該組成物からなる被膜 を有する電子部品およびプリント基板などの半田用電子部材、該組成物を用いる半 田づけ方法、さらに半田づけされた上記電子部材を含む電気製品を提供することを 目的としている。  [0010] In view of the above problems, the present invention provides a flux that can exhibit high, high flux and anti-raising performance in the use of solder in surface mounting, which has been increasing recently.

式 (a)中、 R1は、水素原子またはメチル基である。 In the formula (a), R 1 is a hydrogen atom or a methyl group.
Rfは、ポリフルォロアルキル基である。このポリフルォロアルキル基は、アルキル基 の水素原子の 2個以上がフッ素原子に置換された基を意味し、このアルキル基の炭 素 炭素結合間に挿入されたエーテル性酸素原子を含むものであってもよい。本明 細書において、ポリフルォロアルキル基または Rf基の表記は、炭素 炭素結合間に 挿入されたエーテル性酸素原子を含むポリフルォロアルキル基の上位概念にあたる ものとして、特にことわりのない限り、該酸素原子を含まないおよび含む両方のポリフ ルォロアルキル基の総称を意味する。 R f is a polyfluoroalkyl group. The polyfluoroalkyl group means a group in which two or more hydrogen atoms of the alkyl group are substituted with fluorine atoms, and includes an etheric oxygen atom inserted between the carbon-carbon bond of the alkyl group. There may be. In this specification, the notation of a polyfluoroalkyl group or R f group is a superordinate concept of a polyfluoroalkyl group containing an etheric oxygen atom inserted between carbon-carbon bonds, unless otherwise specified. It means a generic term for both polyfluoroalkyl groups not containing and containing the oxygen atom.
[0023] 上記ポリフルォロアルキル基 (Rf基)は、通常、炭素数 1〜20のアルキル基に対応 するフッ素置換数 2以上の基であり、直鎖構造または分岐構造のいずれであってもよ い。たとえば、メチル、ェチル、プロピル、ブチル、ペンチル、へキシル、ヘプチル、ォ クチル、ノ-ルなどの直鎖または分岐構造のアルキル基に対応する部分フルォロ置 換またはパーフルォロ置換アルキル基、ォキシポリフルォロエチレン、ォキシポリフル ォロプロピレンなどのォキシポリフルォロアルキレン繰り返し単位を有する基などが挙 げられる。分岐構造のポリフルォロアルキル基としては、イソプロピル基、 3—メチルブ チル基、 5—メチルへキシル基、 7—メチルォクチルのパーフルォロ置換アルキル基 などが挙げられる。 [0024] なお、構造的により高い剛直性を必要とする場合は、 Rf基のノ¾ /キングを良くするた め、 Rf基として、エーテル性酸素原子を含まないポリフルォロアルキル基が選択され 、特にエーテル性の酸素原子を含まな ヽパーフルォロアルキル基が選択される。 [0023] The polyfluoroalkyl group (R f group) is usually a group having 2 or more fluorine substituents corresponding to an alkyl group having 1 to 20 carbon atoms, and has either a linear structure or a branched structure. It's good. For example, a partially or perfluoro-substituted alkyl group corresponding to a linear or branched alkyl group such as methyl, ethyl, propyl, butyl, pentyl, hexyl, heptyl, octyl, nor, And groups having an oxypolyfluoroalkylene repeating unit such as loethylene and oxypolyfluoropropylene. Examples of the branched polyfluoroalkyl group include isopropyl group, 3-methylbutyl group, 5-methylhexyl group, and 7-methyloctyl perfluoro-substituted alkyl group. [0024] In the case that requires structurally higher stiffness is order to improve the Roh ¾ / King of the R f group as the R f group, the polyfurfuryl O b alkyl group containing no etheric oxygen atom In particular, a perfluoroalkyl group containing an etheric oxygen atom is selected.
[0025] 本発明にお 、て、 Rf基は、実質的に全フッ素置換されたパーフルォロアルキル基( 以下、 基とも記す)が好ましぐ炭素数 1〜20の RF基が好ましい。特に主鎖の鎖長 (側鎖を含まな 、炭素数)が 1〜6の RF基が好ま U、。 [0025] Te you, the present invention, R f group is substantially all fluorine-substituted per full O b alkyl group (hereinafter, also referred to as a group) is preferred instrument R F group having 1 to 20 carbon atoms preferable. In particular, an R F group having a main chain length (including side chains, carbon number) of 1 to 6 is preferred.
Rf基は直鎖構造または分岐構造の 、ずれであってもよ!/、が、直鎖構造が好ま 、。 分岐構造である場合には、分岐部分が Rf基の末端部分に存在し、かつ、炭素数 1〜 3程度の短鎖である場合が好まし 、。 The R f group may be either a straight chain structure or a branched structure! /, But a straight chain structure is preferred. In the case of a branched structure, it is preferable that the branched portion is present at the terminal portion of the R f group and is a short chain having about 1 to 3 carbon atoms.
[0026] 本発明の這い上がり防止剤において、 Rf鎖長と這い上がり防止性能とに格別な相 関はない。 Rf基の主鎖の鎖長が 8を越えても、這い上がり防止性能を低下させること はないが、撥油性が強くなり、被処理部品の後加工性に大きな影響を与えてしまう場 合がある。 [0026] In the scooping preventive agent of the present invention, there is no particular correlation between the Rf chain length and scooping preventing performance. Even if the chain length of the main chain of the R f group exceeds 8, the anti-cracking performance will not be reduced, but the oil repellency will increase and the post-processability of the parts to be processed will be greatly affected. There is.
なお、 Rf鎖長と撥水または撥油性能には密接な関係があり、 Rf鎖長の炭素数が 8以 上になると非常に高い撥水撥油性を示すことができる。なお、撥水撥油性について は、接触角を指標とすることができる。たとえばドデカンなどの油に対する接触角が大 きいほど、高い撥油性をもっといえる。 There is a close relationship between the R f chain length and water or oil repellency, and when the R f chain length has 8 or more carbon atoms, extremely high water and oil repellency can be exhibited. For water / oil repellency, the contact angle can be used as an index. For example, the higher the contact angle with oil such as dodecane, the higher the oil repellency.
[0027] し力しながら、這 、上がり防止性能と Rf鎖長に格別な相関はな 、ため、被処理部品 の後加工性の面から、共重合体中、化合物(a)から導かれる単位における全 Rf基の 90質量%以上が、主鎖炭素数 6以下、より好ましくは 3以下の RF基である。 [0027] However, there is no particular correlation between the rise prevention performance and the R f chain length, however, because of the post-processability of the processed part, it is derived from the compound (a) in the copolymer. more than 90% by weight of the total the R f group is in the unit, the main chain carbon atoms of 6 or less, more preferably 3 or less of R F group.
