合成例1〜11により得られた、各酸性リン酸エステルと金属とのアダクトと、粘稠性物質と、低粘度液体と、をそれぞれ所定の割合で常温にて混合することにより、本液状組成物を調製した。
G−UR:ウレア系グリース(和光ケミカル社製「BMG−U/ブームグリース」、稠度265)
G−Li:リチウム石鹸系グリース(東レダウコーニング社製「モリコート」、稠度260)
G−Ca:カルシウム石鹸系グリース(住鉱潤滑剤社製「スミグリースシャシー」、稠度280)
なお、稠度は、JIS K2220に準拠して測定した、25℃におけるものである。
n−ヘキサン:動粘度0.37mm2/s、沸点68℃
n−ドデカン:動粘度1.46mm2/s、沸点216℃
酢酸ブチル:動粘度0.78mm2/s、沸点126℃
イソドデカン:動粘度1.35mm2/s、沸点177℃
なお、動粘度は、JIS K2283に準拠して測定した、40℃におけるものである。
調製した各本液状組成物について、JIS Z8803に準拠して、常温における粘度を測定した。粘度が10Pa・s未満のものを良好「○」、粘度が10Pa・s以上のものを不良「×」とした。
常温下で、調製した各本液状組成物に、5×50×0.2mmの短冊状銅板を30秒間浸漬し、取り出した後、水平の状態で、100℃のオーブンに20分間放置後、2時間常温放置した。その後、塗布表面を目視で観察し、ムラなく均一に塗布できているものを合格「○」、波打つようなムラが生じ、均一に塗布できていないものを不合格「×」とした。
均一塗布性の評価において合格であったものについて、垂直に立てかけたまま、120℃の恒温槽に48時間放置し、取り出して常温まで放冷した後、再び塗布表面を目視で観察した。恒温槽に投入する前と同様、均一に塗布された状態が維持されているものは合格「○」、垂れ落ちが生じているものを不合格「×」とした。
