Description
(1)テトラフルオロプロペン冷媒と、
平均分子量が800〜1200で、両末端にアシル基を有するポリプロピレングリコールに、(A)フェノール系ラジカル反応抑制剤を0.5〜2質量%、(B)分子中にエステル基を持たないエポキシ系酸捕捉剤を0.5〜4質量%及び(C)(C−1)リン系極圧剤及び(C−2)グリセリンと分子中に1または2個の不飽和結合を有する脂肪酸とからなるモノエステルの少なくとも一方を0.5〜2質量%添加した冷凍機油組成物とを含有することを特徴とするカーエアコン用作動流体。
冷媒として2,3,3,3−テトラフルオロ−1−プロペンを用い、表1に示す基油とともに規定のガラス管に封入し、湯浴によりゆっくり加熱した。そして、均一な層から油層と冷媒層とに分かれる温度を測定した。尚、基油量は5質量%または15質量%とした。結果を表1に併記する。
試験例1で用いた実施例1、2、比較例1、3、9、11、12の各基油の動粘度及び粘度指数を測定した。結果を表2に示すが、実施例1、2の基油は動粘度及び粘度指数ともに実用的である。これに対し、比較例12の基油は、両末端アシル基変性プロピレングリコールであるが、分子量が800未満であり、流動性に劣り実用的ではない。
実施例1の基油に表3に示す如く添加剤を添加し、2,3,3,3−テトラフルオロ−1−プロペンと混合して試料を調製した。尚、添加量は基油に対する割合である。そして、シールドチューブ試験(JIS K2211準拠)により試料の変色、全酸価及び析出物の有無を評価した。試験条件は下記の通りであり、結果を表3に併記する。
・油/冷媒 : 2mL/2mL
・試験温度 : 175℃
・試験期間 : 14日間
・油中水分量: 2000ppm
・管内空気量: 分圧0.1mmHg以下
・触媒 : 鉄線、銅線、アルミ線を各3cm
チオリン酸系ラジカル反応抑制剤:ジアルキルジチオリン酸亜鉛
グリシジルエーテル系酸捕捉剤:アルキルグリシジルエーテル
イミド系酸捕捉剤:ビス(ジアルキルフェニル)カルボジイミド
リン酸系極圧剤:トリアリールホスフェート
チオリン酸系極圧剤:トリアルキルフェニルチオホスフェート
グリセリド系油性向上剤:グリセリンモノエステル
硫化油脂:硫化なたね油
実施例1の基油に、試験例3で用いたフェノール系ラジカル反応抑制剤を1質量%、グリシジルエーテル系酸捕捉剤を1質量%添加し、更に表4に示す如く試験例3で用いたリン酸系極圧及びグリセリド系油性向上剤を添加し、2,3,3,3−テトラフルオロ−1−プロペンと混合して試料を調製した。尚、添加量は基油に対する割合である。そして、FALEX試験(Pin−Vee Block)により耐焼付性及び耐摩耗性を評価した。試験条件は下記の通りであり、結果を表4に併記する。
・耐焼付性:50℃、慣らし250lbs×5分、回転数290rpm
・耐摩耗性:50℃、300lbs×2時間、回転数290rpm
