Description
[2]潤滑油基油の尿素アダクト値が2.5質量%以下である、[1]に記載の潤滑油組成物。
[3]ポリ(メタ)アクリレートをさらに含有する、[1]又は[2]に記載の潤滑油組成物。
[4]共重合体の含有量に対するポリ(メタ)アクリレートの含有量の質量比が0.4以下である、[3]に記載の潤滑油組成物。
[5]自動変速機に用いられる、[1]~[4]のいずれかに記載の潤滑油組成物。
本実施形態に係る潤滑油組成物は、100℃における動粘度が2.0~3.5mm2/sである潤滑油基油を含有する。潤滑油基油は、潤滑油基油全量を基準として、50質量%以上の水素化脱ろう油成分を含む。潤滑油基油は、水素化脱ろう油成分と水素化脱ろう油成分以外の基油成分とから構成される混合油であり得る。
(I)100℃における動粘度:1.0mm2/s以上2.0mm2/s未満、40℃における動粘度:2.0mm2/s以上6.0mm2/s未満、好ましくは3.0~5.0mm2/s
(II)100℃における動粘度:2.0mm2/s以上3.5mm2/s未満、好ましくは2.0~3.0mm2/s、40℃における動粘度:6.0mm2/s以上14mm2/s未満、好ましくは7.0~13mm2/s、粘度指数:90以上、好ましくは95~150
(III)100℃における動粘度:3.5mm2/s以上4.5mm2/s未満、好ましくは3.5~4.3mm2/s、40℃における動粘度:14mm2/s以上28mm2/s未満、好ましくは14~21mm2/s、粘度指数:110以上、好ましくは120~160
(IV)100℃における動粘度:4.5~20mm2/s、好ましくは4.8~11mm2/s、より好ましくは5.5~8.0mm2/s、40℃における動粘度:28~50mm2/s、好ましくは29~45mm2/s、粘度指数:110以上、好ましくは120~180
(1)パラフィン基系原油及び/又は混合基系原油の常圧蒸留残渣油の減圧蒸留による留出油(WVGO)
(2)潤滑油脱ろう工程により得られるワックス(スラックワックス等)及び/又はガストゥリキッド(GTL)プロセス等により得られる合成ワックス(フィッシャートロプシュワックス、GTLワックス等)
(3)基油(1)~(2)から選ばれる1種又は2種以上の混合油及び/又は当該混合油のマイルドハイドロクラッキング処理油
(4)基油(1)~(3)から選ばれる2種以上の混合油
(5)パラフィン基系原油及び/又は混合基系原油の常圧蒸留残渣油の減圧蒸残渣油の脱れき油(DAO)
(6)基油(5)のマイルドハイドロクラッキング処理油(MHC)
(7)基油(1)~(6)から選ばれる2種以上の混合油
(8)上記基油(1)~(7)から選ばれる基油又は当該基油から回収された潤滑油留分を水素化分解し、その生成物又はその生成物から蒸留等により回収される潤滑油留分について水素化脱ろう(接触脱ろう)処理を行い、又は当該脱ろう処理をした後に蒸留することによって得られる水素化脱ろう油成分
本実施形態に係る潤滑油組成物は、エチレンに由来する構造単位及び酢酸ビニルに由来する構造単位を含み、重量平均分子量が8000~12000である共重合体を含有する。共重合体中の酢酸ビニルに由来するアセトキシ基(-OCOCH3基)による立体障害によって、潤滑油基油中のパラフィン同士の相互作用を低下させ、潤滑油基油が結晶化することを防ぐことが可能となる。そのため、当該共重合体は、例えば、特開平10-237469号公報、特開平11-181453号公報、特開2005-15798号公報等に開示されているように低温流動性向上剤(流動点降下剤)として作用し得る。
本実施形態に係る潤滑油組成物は、ポリ(メタ)アクリレートをさらに含有していてよい。ポリ(メタ)アクリレートは、共重合体と同様に、低温流動性向上剤(流動点降下剤)として作用し得る。なお、ポリ(メタ)アクリレートは、ポリアクリレート又はポリメタクリレートを意味する。
潤滑油組成物は、その目的に応じて、一般的に使用されている任意の潤滑油用添加剤をさらに含有することができる。このような添加剤としては、例えば、金属系清浄剤、無灰分散剤、摩擦調整剤、摩耗防止剤(極圧剤)、酸化防止剤、腐食防止剤、防錆剤、抗乳化剤、金属不活性化剤、消泡剤等を挙げることができる。
[潤滑油組成物の調製]
表1、表2、及び表3に示すように、実施例1~16及び比較例1~8の潤滑油組成物をそれぞれ調製した。得られた潤滑油組成物について、動粘度(40℃及び100℃)、粘度指数、BF粘度(-40℃)、流動点等を測定した。なお、潤滑油基油は、以下の2種の基油成分からなる混合油であり、表1、表2、及び表3における動粘度、粘度指数、及び尿素アダクト値の項目は混合油の数値を意味する。また、混合油の尿素アダクト値は、各基油成分の尿素アダクト値から、その仕込み量における尿素アダクト値を求め、その和を混合油の尿素アダクト値として求めた。例えば、後述の潤滑油基油X-1の尿素アダクト値は、以下のように求めることができる。
潤滑油基油X-1:
尿素アダクト値=1.0×0.80+2.2×0.20=1.2[質量%]
A-1:水素化脱ろう油成分(100℃動粘度:2.2mm2/s、40℃動粘度:7.3mm2/s、粘度指数:106、API基油グループ:グループII、尿素アダクト値:1.0質量%)
A-2:水素化脱ろう油成分(100℃動粘度:4.2mm2/s、40℃動粘度:19.4mm2/s、粘度指数:124、API基油グループ:グループIII、尿素アダクト値:2.2質量%)

JIS K2283に準拠し、各潤滑油組成物の40℃及び100℃における動粘度並びに粘度指数を測定した。
(2)BF粘度
ASTM D 2983に準拠し、各潤滑油組成物の-40℃におけるBF粘度を測定した。本試験においては、BF粘度の値が小さいほど(例えば、12000mPa・s以下)、低温流動性に優れていることを意味する。一方、潤滑油組成物のBF粘度の値が小さすぎると(例えば、3000mPa・s未満)、オイル漏れが生じる傾向にある。そのため、BF粘度は、低温流動性とシール性とのバランスの観点から、特定の範囲(例えば、3000~12000mPa・s)にあることが好ましい。
(3)流動点
JIS K2269に準拠し、各潤滑油組成物の流動点を測定した。本試験においては、流動点が低いほど(例えば、-35℃以下)、低温流動性に優れていることを意味する。
