8. 酸成分とアルカリ成分を含み、かつ前記の酸成分とアルカリ成分の配合比の調整により、pHを調整して得られる上記7に記載の硬脆性材料用加工液
を提供するものである。
前記酸素含有基としては、例えば、カルボキシル基、水酸基およびオキシエチレン基、およびオキシプロピレン基が挙げられる。ここで、このカルボキシル基や水酸基は、脱プロトン化や中和によってアニオンになっているものも含む。
なお、水溶性高分子化合物とは水に溶ける高分子化合物であり、通常、水に対する溶解度(20℃)が0.1g/水100g以上である高分子化合物をいう。また、本明細書においてスラリーとは加工液および砥粒を含有する混合物をいう。
前記カルボン酸系高分子化合物は重合性基を有する不飽和カルボン酸を重合して得られる高分子化合物である。不飽和カルボン酸としては、例えば、アクリル酸、メタクリル酸、無水マレイン酸、マレイン酸、フマル酸、クロトン酸およびイタコン酸等が挙げられる。カルボン酸系高分子化合物の具体例としては、ポリアクリル酸、ポリメタクリル酸、ポリクロトン酸、ポリイタコン酸、ポリマレイン酸、ポリフマル酸、アクリル酸-メタクリル酸共重合体、アクリル酸-イタコン酸共重合体、アクリル酸-マレイン酸共重合体、アクリル酸-アクリルアミド共重合体、アクリル酸-アクリル酸エステル共重合体、アクリル酸-メタクリル酸エステル共重合体、アクリル酸-スルホン酸系モノマー共重合体、アクリル酸-ビニルピロリドン共重合体等が挙げられる。また、カルボン酸系高分子化合物はこれらの重合体の塩であってもよく、例えば、ポリアクリル酸ナトリウム、ポリアクリル酸カリウム、ポリアクリル酸アンモニウム等が挙げられる。
前記アルキレングリコール系高分子化合物は、アルキレングリコールの重合体であって、例えばポリアルキレングリコールやその誘導体等が挙げられる。アルキレングリコール系高分子化合物の具体例としては、ポリエチレングリコール、ポリプロピレングリコール、酸化エチレンおよび酸化プロピレンのブロック共重合体、並びにこれらの重合体の誘導体(例えばエステル誘導体、エーテル誘導体等)が挙げられる。これらの中でオキシエチレン基を有する重合体が好ましい。
PO含有非イオン界面活性剤は、数平均分子量が70~5,000の化合物が好ましく、100~4,000の化合物がより好ましい。PO含有非イオン界面活性剤は、オキシプロピレン基が分子全体の40~90質量%を占めることが好ましく、50~80質量%を占めることがより好ましい。
これらの添加剤の配合量は、目的に応じて適宜選定すればよいが、これらの添加剤の合計が加工液全量を基準にして、通常0.01~5質量%程度である。
上記のように本発明の硬脆性材料用加工液を含有するスラリーは比較的低い粘度を有するものであり、また、通常、水含有率は高くなる。一般にこのような場合は、遊離砥粒方式では砥粒が沈降し易くなるが、本発明の硬脆性材料用加工液は上記の成分(B)と成分(C)を併用するものであり、これにより優れた砥粒分散安定性が得られる。
第1表に示す組成の加工液を調製した。なお、表中の値は質量部を表す。
水溶性高分子化合物2:ポリアクリル酸〔日本触媒(株)製、商品名アクアリックAS58〕(数平均分子量106,000、重量平均分子量798,000)
水溶性高分子化合物3:ポリアクリル酸ナトリウム〔日本触媒(株)製、商品名アクアリックDL365〕(数平均分子量2,500、重量平均分子量5,400)
非イオン界面活性剤1:1質量%水溶液における曇点が30℃のEO-POブロック共重合体、分子全体におけるオキシプロピレン基の割合79質量%〔三洋化成工業(株)製、商品名ニューポールPE62〕(数平均分子量2,500)
非イオン界面活性剤2:1質量%水溶液における曇点が56℃のEO-POブロック共重合体、分子全体におけるオキシプロピレン基の割合59質量%〔三洋化成工業(株)製、商品名ニューポールPE74〕(数平均分子量3,400)
なお、数平均分子量および重量平均分子量は、GPC(ゲルパーミエーションクロマトグラフィー)法によって得られた値である。(分子量標準サンプル:ポリアクリル酸ナトリウム)
A:水分80質量%以上
B:水分40質量%以上、80質量%未満
C:水分40質量%未満
得られた加工液について、以下に示す方法で砥粒分散安定性試験を行った。
砥粒((株)フジミインコーポレーテッド製GC#1500)と加工液を1:1の質量比で混合しスラリーを調製した。調製直後のスラリー100mlをシリンダー(内径:28mm、容量120ml)に入れ、30℃で静置した。5時間後に、液分離層(砥粒と加工液が分離した層)の割合を以下の計算式により求めた。
液分離層の比率(%)=液分離層の体積(ml)/全体の体積(ml)×100
結果を第2表に示す。
砥粒分散安定性試験と同様の方法によってスラリーを調製し、100mlのスラリーをシリンダー(内径:28mm、容量120ml)に入れて静置した。24時間後にシリンダーを反転させ、堆積していた砥粒が流動した量(ml)を1時間後に測定した。結果を第2表に示す。
砥粒((株)フジミインコーポレーテッド製GC#1500)と加工液を1:1の質量比で混合しスラリーを調製した。調製直後のスラリーの25℃における粘度を、B型回転粘度計〔東機産業(株)製TVB-10〕を用いて測定した。結果を第2表に示す。
試験条件
試験機:(株)オリエンテック製「F-2100」
球:3/16インチSUJ2
試験板:多結晶シリコン
摺動速度:20mm/s
摺動距離:2cm
荷重:1.96N
上記試験条件で往復動摩擦試験を行い、摩擦係数を測定した。結果を第2表に示す。
また、実施例の加工液は、往復動摩擦試験による摩擦係数が0.10~0.12と低く、したがって、固定砥粒ワイヤソーを用いる方式においては、固定砥粒の剥離を抑制することができ、かつ切断抵抗も低減することができる。
