若依本發明，可提供一種包含碳中和成分、顯示良好潤滑性且金屬腐蝕性低之潤滑劑。According to the present invention, a lubricant containing carbon-neutral components, showing good lubricity and low metal corrosion can be provided.
用以實施發明之形態 於本說明書中，就較佳數值之範圍(例如含量等之範圍)而言，以階梯式記載之下限值及上限值可各自獨立地予以組合。舉例來說，可從「宜為10~90，較佳為30~60」之記載中，將「理想之下限值(10)」與「較佳之上限值(60)」組合成「10~60」。同樣地，本說明書中與數值範圍之記載相關之「以上」、「以下」、「小於」、「大於」之數值為可任意組合之數值。 Form used to implement the invention In this specification, with respect to the range of preferred numerical values (such as the range of content, etc.), the lower limit and upper limit described in a stepwise manner can be combined independently. For example, from the description "10 to 90 is preferred, and 30 to 60 is preferred", the "ideal lower limit value (10)" and the "preferable upper limit value (60)" can be combined into "10 ~60". Similarly, the numerical values "above", "below", "less than" and "greater than" related to the description of numerical ranges in this specification are numerical values that can be combined arbitrarily.
[潤滑劑] 本實施形態之潤滑劑為含有由氫鍵受體與氫鍵施體構成之深共晶溶劑且鹵素原子含量為0.1質量%以下之物。 潤滑劑中之鹵素原子含量若大於0.1質量%，對金屬之腐蝕性將會提高。 以下，針對本實施形態之潤滑劑所含各成分進行說明。 [Lubricant] The lubricant of this embodiment contains a deep eutectic solvent composed of a hydrogen bond acceptor and a hydrogen bond donor, and has a halogen atom content of 0.1 mass % or less. If the halogen atom content in the lubricant is greater than 0.1% by mass, the corrosiveness to metals will increase. Each component contained in the lubricant of this embodiment will be described below.
＜深共晶溶劑＞ 本實施形態之潤滑劑所含深共晶溶劑不同於由陽離子種與陰離子種構成之離子液體，係由氫鍵受體與氫鍵施體構成者，且藉由混合此等2種成分而發生共晶熔點降低。 深共晶溶劑於常溫(25℃)下可為液態物亦可為固態物，從作為潤滑劑之處置性觀點來看，以常溫(25℃)下呈液態之物為宜。 ＜Deep eutectic solvent＞ The deep eutectic solvent contained in the lubricant of this embodiment is different from the ionic liquid composed of cationic species and anionic species, but is composed of a hydrogen bond acceptor and a hydrogen bond donor, and is generated by mixing these two components. The eutectic melting point is lowered. The deep eutectic solvent can be liquid or solid at normal temperature (25°C). From the perspective of handleability as a lubricant, it is suitable to be liquid at normal temperature (25°C).
本實施形態之潤滑劑於使用深共晶溶劑來作為基劑時，相對於潤滑劑全量，宜含深共晶溶劑50質量%以上，且較宜含70質量%以上，更宜含90質量%以上。 另一方面，將上述深共晶溶劑用作添加劑時，相對於潤滑劑全量，亦可含有深共晶溶劑0.1~10質量%左右。 When the lubricant of this embodiment uses a deep eutectic solvent as a base, it is preferable to contain more than 50 mass% of the deep eutectic solvent relative to the total amount of the lubricant, and more preferably it contains more than 70 mass%, and more preferably it contains 90 mass%. above. On the other hand, when the above-mentioned deep eutectic solvent is used as an additive, the deep eutectic solvent may be contained in an amount of about 0.1 to 10% by mass relative to the total amount of the lubricant.
＜氫鍵受體＞ 本實施形態之潤滑劑所含氫鍵受體僅需為與氫鍵施體形成共晶之物即可。然而，如同上述，由於本實施形態之潤滑劑中之鹵素原子含量需在0.1質量%以下，氫鍵受體以不含鹵素原子者為宜，其具體例可舉如甜菜鹼。 ＜Hydrogen bond acceptor＞ The hydrogen bond acceptor contained in the lubricant of this embodiment only needs to form a eutectic with the hydrogen bond donor. However, as mentioned above, since the halogen atom content in the lubricant of this embodiment needs to be less than 0.1% by mass, it is preferable that the hydrogen bond acceptor does not contain halogen atoms, and a specific example thereof is betaine.
就上述甜菜鹼而言，更具體來說宜為下列通式(1)所示者。 [化學式1] (式中，R 1~R 3各自獨立為碳數1~5之烴基，n為1~3之整數)。 上述R 1~R 3宜各自獨立為碳數1~3之烷基，較宜為碳數1或2之烷基。 上述n宜為1或2。 上述通式(1)所示甜菜鹼之具體例可舉如N,N,N-三甲甘胺酸。 就氫鍵受體而言，可單獨使用上述者中之1種，亦可組合2種以上來使用。 The above-mentioned betaine is more specifically preferably represented by the following general formula (1).

＜氫鍵施體＞ 本實施形態之潤滑劑所含氫鍵施體僅需為與氫鍵受體會形成共晶之物即可。然而，如上所述，由於本實施形態之潤滑劑中之鹵素原子含量需在0.1質量%以下，故氫鍵施體以不含鹵素原子者為宜，更具體例來說，較宜為選自醇、羧酸及含氮化合物中之1種以上。 ＜Hydrogen bond donor＞ The hydrogen bond donor contained in the lubricant of this embodiment only needs to be a substance that forms a eutectic with the hydrogen bond acceptor. However, as mentioned above, since the halogen atom content in the lubricant of this embodiment needs to be 0.1% by mass or less, the hydrogen bond donor is preferably one that does not contain halogen atoms.
