Description

【発明の詳細な説明】 ［、産業上の利用分野］ 本発明はポリエーテルエーテルケトン（以下、ｒＰＥＥ
ＫＪと略記する。）製部材の接合方法に係り、特に、Ｐ
ＥＥＫ製のパイプ、継手、バルブ等の配管部品等の接合
に有効なＰＥＥＫ製部材の接合方法に関する。
［従来の技術］ 従来の配管等の接合技術には、次のようなものがある。
■　接着：　有機溶剤（接着剤）にて被接合材の母材を
溶かして、これを押しつけて一体化する。
■　熱溶着：　熱で被接合材の母材を溶かして、これを
押しつけて一体化する。
■　熱溶接：　熱で被接合材の母材に溶接棒を溶は込ま
せて一体化する。
［発明が解決しようとする問題点］ 上記■〜■の接合方法は、次のような理由から、ＰＥＥ
Ｋ製の部材には適用することができない。
■の接着方法は、ＰＥＥＫに適当な、即ちＰＥＥＫを溶
かすことができる有機溶剤（接着剤）がないため、適用
することができない。
■、■の方法によれば、熱でＰＥＥＫを溶かして接合す
ることが可能であるが、この場合、溶融部に気泡が発生
し、この気泡は接合後においても接合部に残存すること
となる。接合部に気泡が残存すると、接合強度は著しく
弱いものとなる上に、接合部に無数の凹凸ができ、実用
には供し得ない接合部材とな、る。
このようなことから、従来より、ＰＥＥＫ製部材に好適
な接合技術の出現が切望されていた。
［問題点を解決するための手段］ 本発明のＰＥＥＫ製部材の接合方法は、ＰＥＥＫ製部材
の被接合部を加熱溶融させて接合する方法において、少
なくとも被接合部近傍を加温して非発泡化処理した後、
溶融接合することを特徴とする。
［作用］ ＰＥＥＫ成形品は、所定温度に所定時間保持することに
より、非発泡化処理することが可能であ　−る、そして
、非発泡化処理したものは、加熱溶融の際に気泡が発生
することが殆どない。
本発明においては、ＰＥＥＫ製部材の加熱溶融接合に先
立ち、少なくとも被接合部近傍を加温して非発泡化処理
するため、加熱溶融接合時の気泡発生が防止され、接合
部に気泡が残存することによる種々の問題が解決される
。
［実施例］ 以下、図面を参照して本発明の実施例方法について説明
する。
第１図〜第４図は本発明のＰＥＥＫ製部材の接合方法の
一例として、ＰＥＥＫ製配管を接合する場合を示す図で
ある。
本発明の方法に従って、ＰＥＥＫ製配管の接合を行なう
には、まず、接合する配管部品、例えば、バイブ、継手
、バルブ等を準備し、バイブ等は必要な長さに切断する
。そして、これらの配管部品の全体又は被接合部近傍を
ヒーターで加温し、一定時間この温度を維持して、非発
泡化処理する。
この場合、加温の程度、時間等は被接合部の形状や大ぎ
さ等によっても異なるが、通常の場合、２００〜２４０
℃で１〜３時間程度を目安として適宜決定される。処理
温度が比較的低い場合には、保持時間を長めに設定し、
逆に処理温度が比較的高い場合には、保持時間は若干短
かめでも十分に目的を達し得る。この処理は、接合する
部品の状態、例えば保管期間即ち古さや保管状況等によ
っても異なるため、適宜温度や時間を調節するのが好ま
しい。
加温は、短管、継手等の小物部品については、全体を恒
温炉に入れることにより容易に行なうことができる。一
方、比較的長さの長いバイブ等は、第１図に示す如く、
キャップ形のヒータ１をバイブ２の被接合端に嵌め込み
、バイブ２の外周には適当な保温材３を取り付けて加温
するのが有利である。第１図に示す方法では、ヒータ１
がバイブ２の端面にも当接するように構成されており、
バイブ内周面からの加温、外周面の保温と共に、端面の
加温も行なえるため、加温効率が良い。勿論、加温はバ
イブ内周面からの加温、バイブ外周面からの加温、バイ
ブ端面からの加温のいずれによる加温でも良い。
次に′、接合する部品の被接合端面同志の間に隙間が生
じないように、端面を平滑に仕上げ処理する。即ち、被
接合端面同志の間に隙間が生じると、十分に溶着するこ
とができなくなるため、隙間なく当接可能に被接合端面
を切削、研磨等の処理を施すことにより、成形する。
この場合において、第２図に示す如く、バイブ２の被接
合端面２ａの内周側エツジ部を若干削り落として面取り
しておくのが好ましい、このようにすることにより、溶
着の際のバイブ内周側の母材の盛り上り（第４図（Ｃ）
のＡの部分）を小さくし、バイブの内周面を平滑化する
ことができる。
このような成形処理を施した後は、溶着部に塵埃等の夾
雑物が混入しないように、被接合端面及びその近傍を適
当な溶剤等で拭き取り、表面を清浄な状態とする。なお
、上記の成形処理は非発泡化処理の前に行なうことも可
能であるが、非発泡化処理後に成形処理を行なう方が、
被接合端面の当接をより良くすることができる。
以上の如き前処理を行なった後、加熱溶融接合を行なう
。
加熱溶融接合に際しては、第３図に示す如く、バイブ２
と、これに接合する継手４等の部品の各々の端面２ａ、
４ａ間にヒータ５を配置し、ヒータ５の輻射熱で両端面
２ａ、４ａを加熱して、被接合端面近傍を溶融させる。
加熱溶融させる範囲は、接合する部品の大きさ等によっ
ても異なるが、一般には、端面から数ｍｍ程度の範囲（
第３図のＢの範囲）にわたって溶融された状態とする。
加熱溶融条件は接合する部品の大きさ、形状等によって
も異なるが、一般には、ヒータ５の表面温度が高いほど
、良好な溶融状態を得られる傾向にある。第３図に示す
方法においては、ヒータ５の温度、ヒータ５とバイブ２
又は継手４との距離、加熱時間等を適宜選定することに
より溶融の程度を調節することができる。
加熱溶融後、ヒータ５を取り除く（第４図（ａ））。そ
して、溶融部２ｂ、４ｂを当接させ（第４図（ｂ））、
更に押し付けて例えば数ｍｍ押し込み、バイブ２と継手
４の材料同志を溶は込ませて一体化させる。これにより
、第４図（Ｃ）に示す如く、溶融接合部Ａが盛り上る如
くして接合されるが、前述の如く面取りを施しであると
、この盛り上りは極めて小さなものとなる。
その後、溶融によって変色していた材料が母材と同色に
戻るまで、溶融部を固定し、溶融部が冷えて固まり、充
分な強度になった後、接合処理を終了する。
なお、図示の例では、溶着により接合する場合について
示したが、本発明の方法は、溶接棒を用いる溶接方法に
よっても同様にして、強固辷接合することができる。
以上、バイブの接合を例示して説明したが、本発明の方
法はバイブ等の配管部品に限らず、板状部材等、あらゆ

以下、具体的な実験例について説明する。
実験例１（本発明例） 第１図〜第４図に示す方法に従って、ＰＥＥＫ製バイツ
バイブ５Ａ）の接合を行なった。
非発泡化処理条件及び溶融条件は下記の通りとした。
匪ｊ口１飢皇」Ｌｋ侘 温度：２４０℃ 時間：２時間 １監ゑ豆 ヒータ表面温度：５７０℃ ヒータとバイブ端面との距離：１．５ｍｍ加熱時間：　
４５ｓｅｃ 加熱溶融後、バイブ同志を押し付けて、１．５ｍｍ押し
込んだ、その後、溶融部の色が母材と同じ色になってか
ら、更に３０秒間固定した後、接合を終了した。
得られた接合部材の引張強度を引張試験機による破壊試
験により測定し、結果を第１表に示した。
また、接合部の表面（内、外面）を観察し、結果を第１
表に記した。
実験例２（比較例） 加温による非発泡化処理を行なわなかったこと以外は、
実験例１と同様にして接合を行ない、接合部の強度を測
定し、また接合部の表面を調べた。結果を第１表に示す
。
第１表より、本発明の方法によれば、高強度で良好な接
合部材が得られることが明らかである。
第１表 ［発明の効果］ 以上詳述した通り、本発明のＰＥＥＫ製部材の接合方法
は、ＰＥＥＫ製部材の加熱溶融接合に際し、接合に先立
ち、ＰＥＥＫ製部材の少なくとも被接合部近傍を加温し
て非発泡化処理するものであって、ＰＥＥＫ製部材を、
