以下に示す基油、ジチオリン酸エステル、及びホスホン酸エステルと、その他の添加剤(トリフェニルホスホロチオネート(チオリン酸トリエステル)、酸捕捉剤及び酸化防止剤を含む)1.7質量%とを混合して、冷凍機油を調製した。ジチオリン酸エステル及びホスホン酸エステルの種類及び含有量は表1に示すとおりであり、基油の含有量は、冷凍機油全量から基油以外の成分(添加剤)の含有量の合計を差し引いた残部である。なお、各成分の含有量は、冷凍機油全量を基準とした含有量(質量%)である。
基油1:ペンタエリスリトールと、2-メチルプロパン酸/3,5,5-トリメチルヘキサン酸との混合脂肪酸(混合比(質量比):60/40)とのポリオールエステル(40℃動粘度:46mm2/s、100℃動粘度:6.3mm2/s)
基油2:ネオペンチルグリコール(1モル)及び1,4-ブタンジオール(0.2モル)にアジピン酸(1.5モル)を反応させたエステル中間体に、3,5,5-トリメチルヘキサノール(1.1モル)を更に反応させ、残存した未反応物を蒸留で除去して得たコンプレックスエステル(40℃動粘度:146mm2/s、粘度指数:140)
ジチオリン酸エステル及びホスホン酸エステルの種類及び含有量を表1に示すとおりに変更した以外は、実施例1と同様にして冷凍機油を調製した。
以下の手順で耐摩耗性を評価した。まず、上側試験片としてベーン(SKH-51)、下側試験片としてディスク(SNCM220 HRC50)を用いた摩擦試験装置を、密閉容器の内部に装着した。摩擦試験部位に各冷凍機油600gを導入し、系内を真空脱気した後、冷媒(ジフルオロメタン(R32))100gを導入して加熱した。密閉容器内の温度を110℃とした後、負荷荷重1000N、回転数750rpmの条件で摩耗試験を行い、60分間の試験後のディスクの摩耗量を計測した。摩耗量の値が小さいほど、耐摩耗性に優れていることを意味する。結果を表1に示す。
安定性の評価は、JIS K2211-09(オートクレーブテスト)に準拠して行った。具体的には、水分含有量を1000ppmに調整した冷凍機油30gをオートクレーブに秤取し、触媒(鉄、銅、アルミの線、いずれも外径1.6mm×長さ50mm)と、冷媒(ジフルオロメタン(R32))30gとを封入した後、175℃に加熱し、168時間後の冷凍機油の酸価(JIS C2101)を測定した。結果を表1に示す。なお、比較例2については、耐摩耗性の評価結果が非常に悪かったため、安定性の評価を行わなかった。
