Abstract
Description
本発明は、新規な化合物及びこれを含む潤滑油組成物に関する。 The present invention relates to a novel compound and a lubricating oil composition containing the same.
潤滑油に耐摩耗性および極圧性を付与する為の有効な添加剤として、ジアルキルジチオリン酸亜鉛(ZnDTP)が、長期にわたり、広範な分野の潤滑油に対して用いられてきた。
一方、近年、内燃機関の排出ガスに対する規制は年々厳しさを増しており、排出ガスを浄化するための各種触媒やフィルターの装着が必須のものとなって来ている。例えば、ガソリンエンジンを搭載した車両には、炭化水素(HC)や窒素酸化物(NOx)の浄化を目的として三元触媒が装着されている。また、最近のディーゼルエンジンを搭載した車両には、粒子状物質(PM:Particle Material)の低減を目的として酸化触媒やDPF(Diesel Particulate Filter)が、NOxの浄化を目的としてNOx吸蔵触媒等の後処理装置が装着されるようになってきた。
As an effective additive for imparting wear resistance and extreme pressure properties to lubricating oils, zinc dialkyldithiophosphate (ZnDTP) has been used for a wide range of lubricating oils for a long time.
On the other hand, in recent years, regulations on exhaust gases from internal combustion engines have become more stringent year by year, and it has become essential to install various catalysts and filters for purifying exhaust gases. For example, a vehicle equipped with a gasoline engine is equipped with a three-way catalyst for the purpose of purifying hydrocarbons (HC) and nitrogen oxides (NOx). Also, in vehicles equipped with recent diesel engines, oxidation catalysts and DPFs (Diesel Particulate Filters) are used for the purpose of reducing particulate matter (PM), and NOx storage catalysts are used for the purpose of purifying NOx. Processing devices have come to be installed.
更に、内燃機関においては燃料を燃焼させるが、燃料だけでなく使用される潤滑油(エンジン油)の一部も燃焼室内において燃焼することが避けられないために、エンジン油中に配合されているZnDTPも燃焼し、排出ガス中に亜鉛由来の灰分や、また硫黄分やリン分が含まれることになる。
排出ガスの浄化を目的として装着されている各種の後処理装置においては、排出ガスによる被毒や目詰まりなどによって浄化するための性能が次第に低下していくことが報告されている。例えば、三元触媒は硫黄やリンによる被毒により、また、酸化触媒やNOx吸蔵触媒も硫黄による被毒により著しく性能が低下することが知られている。さらに、DPFは灰分により目詰まりを起こし、車両の運行に悪い影響を及ぼしている。
Furthermore, in an internal combustion engine, fuel is burned, but not only the fuel but also a part of the lubricating oil (engine oil) used is unavoidably burned in the combustion chamber, so it is blended in the engine oil. ZnDTP also burns, and the exhaust gas contains zinc-derived ash, sulfur, and phosphorus.
It has been reported that in various post-treatment devices installed for the purpose of purifying exhaust gas, the performance for purification is gradually lowered due to poisoning or clogging by exhaust gas. For example, it is known that the performance of a three-way catalyst is remarkably deteriorated due to poisoning by sulfur or phosphorus, and that of an oxidation catalyst or a NOx storage catalyst is also significantly deteriorated by poisoning by sulfur. In addition, the DPF is clogged with ash, which adversely affects the operation of the vehicle.
そこで、エンジン油中に使用されているZnDTPの量を減少させることは、これら後処理装置を効果的に作用させ、その使用寿命を延長させ、また環境の保全を図る上で非常に重要であるが、ZnDTPの使用量を減少させた場合にも潤滑油の耐摩耗性を低下させないように維持することが同時に重要である。
こうした背景からZnDTPをはじめとする既知の亜鉛及びリンを含有する添加剤の上記したような欠点を考慮して、亜鉛もリンも含まない、少なくともそれらの含有量を減少させた潤滑油用の添加剤を得るための努力が払われてきた。
このようなものの一環として、無亜鉛(無灰)、無リンの潤滑油添加剤としては、例えば、2,5−ジメルカプト−1,3,4−チアジアゾールと不飽和モノ−、ジ−およびトリ−グリセリドとの反応生成物(特許文献1)、ジアルキルジチオカルバメート誘導有機エーテル(特許文献2)、及び5−アルキル−2−チオン−1,3,4−チアジアゾリジン化合物などが挙げられる(特許文献3)。
Therefore, reducing the amount of ZnDTP used in engine oil is very important for effectively operating these aftertreatment devices, extending their service life, and protecting the environment. However, it is also important to maintain the wear resistance of the lubricating oil so as not to decrease even when the amount of ZnDTP used is reduced.
In view of the above-mentioned drawbacks of known additives containing zinc and phosphorus such as ZnDTP, zinc and phosphorus are added, and at least their contents are reduced for this reason. Efforts have been made to obtain drugs.
As part of such, zinc-free (ashless), phosphorus-free lubricating oil additives include, for example, 2,5-dimercapto-1,3,4-thiadiazole and unsaturated mono-, di- and tri- Reaction products with glycerides (Patent Document 1), dialkyldithiocarbamate-derived organic ethers (Patent Document 2), 5-alkyl-2-thione-1,3,4-thiadiazolidine compounds and the like (Patent Documents) 3).
また、上記した内燃機関用の潤滑油のみならず、機械油、油圧作動油、ギヤ油、グリース等においても、環境に対する負荷を低減するという観点から、亜鉛(Zn)やモリブデン(Mo)などの金属分、リン(P)を含有しないもの又はこれらを低減したものするという要請は一層強くなってきている。
本発明は、亜鉛成分、リン成分を含まず、ZnDTPに替わる新規な化合物及びこれを使用した潤滑油組成物を提供しようとするものである。 The present invention is intended to provide a novel compound that does not contain a zinc component and a phosphorus component and replaces ZnDTP, and a lubricating oil composition using the same.
本発明は、下記の一般式(1)で示される化合物であって、
そして、上記一般式(1)のR1、R2の置換炭化水素中のヘテロ原子は、酸素、硫黄、窒素のいずれかまたはこれらの組み合わせであり、このヘテロ原子は、アルコール、ケトン、エステル、エーテル、ニトリル、アミン、スルフィドリル、チオケトン、チオエステル、チオエーテル、ポリエーテル又はアミドなどの形をとっているものがある。
この化合物は、添加剤として潤滑油組成物中に含有されて使用され、通常、0.1質量%以上の添加量で使用される。

(result)
The results of tests 1 and 2 are shown in Table 1.
(Evaluation)
In Example 4, the wear resistance is improved as can be seen from the shell 4-ball test as compared with Comparative Example 1, and the HTT is improved from 5.0 to 8.0 in Comparative Example (JASO M355: According to the 2005 standard, the passing score is 7.0 or higher), which indicates that the cleanliness is improved and the generation of oxidative degradation products is suppressed.
In addition, as compared with Comparative Example 1, Example 5 is improved in wear resistance as can be seen from the shell four-ball test, and HTT has a score of 8.5, which is equal to or better than Example 4. It can be seen that it is excellent in cleanliness.
Moreover, in the thing using the commercially available ZnDTP (zinc dithiophosphate) shown as the comparative example 2, since there is a zinc metal content, the sulfated ash content is increased, and the phosphorus (P) content is also mixed.
In Examples 4 and 5, the results of HTT are superior to those of Comparative Example 2. Therefore, it can be said that the cleanliness is improved by suppressing the generation of oxidative degradation products. Further, as can be seen from the shell 4-ball test, the wear resistance of Example 4 is equivalent to that of Comparative Example 2, and Example 5 is inferior to Comparative Example 2 but superior to Comparative Example 1. Therefore, it is possible to contribute to the reduction of the phosphorus content in the composition by substituting it for a part of ZnDTP.
Accordingly, both examples can be used in place of Comparative Example 2 using ZnDTP, have good cleanliness, do not contain metal and phosphorus, and are environmentally friendly. It has been shown.
