Description
本發明係關於一種潤滑油添加劑，特別是一種混摻奈米碳球及奈米氮化鋁球為主要成分之潤滑油添加劑。The invention relates to a lubricating oil additive, in particular to a lubricating oil additive which is mainly composed of a carbon nanosphere and a nanometer aluminum nitride ball.
潤滑油常為使用於汽、機車或各式機械內，以減少二物件因接觸摩擦而產生耗損之情形。潤滑油多半是由基礎油與多種添加劑〔例如：清淨劑、分散劑、黏度指數改進劑、抗磨劑或氧化劑等〕調製而成，藉此仰賴添加劑改善潤滑油的使用性能並延長潤滑油的使用壽命。Lubricating oil is often used in steam, locomotives or various types of machinery to reduce the loss of two objects due to contact friction. Lubricating oil is mostly prepared from base oils and various additives (such as detergents, dispersants, viscosity index improvers, anti-wear agents or oxidants), thereby relying on additives to improve the performance of lubricating oils and extend the lubricating oil. Service life.
近年來，由於奈米粉末具有獨特之物理、化學及機械等優異性，故業者遂將其開發成為各種奈米固態潤滑添加劑，以藉此在二物件的摩擦面間建立連續且黏附性佳的奈米薄膜，進而減少二物件相對運動時產生的磨損。該奈米固態潤滑添加劑大致包含有石墨、二硫化鉬、二硫化鎢和聚四氟乙烯等類型，然該些奈米固態潤滑添加劑於實際使用時雖可發揮一定的作用，但卻也產生有以下缺點。In recent years, because nano powder has unique physical, chemical and mechanical properties, it has been developed into various nano solid lubricant additives to establish continuous and good adhesion between the friction surfaces of the two objects. The nano film, in turn, reduces the wear caused by the relative movement of the two objects. The nano solid lubricating additive generally comprises graphite, molybdenum disulfide, tungsten disulfide and polytetrafluoroethylene. However, although the nano solid lubricating additives can play a certain role in actual use, they also have The following disadvantages.
以石墨而言，其碳原子多是排列於一平面上，而形成層層堆疊的層狀結構，以能由層狀構型的平坦表面減少摩擦力的產生。惟，由於層狀結構之石墨具有開放邊界，且排列於邊界之碳原子較為躍動而具有高活性，故當石墨使用在高於325℃的含氧環境時，邊界碳原子係容易與氧作用而氧化生成二氧化碳，以致石墨表面結構改變而失去潤滑效果，更因此導致石墨可能自邊緣產生分散、裂解甚至崩壞等情形，進而降低石墨的使用時效性。In the case of graphite, the carbon atoms are mostly arranged on a plane, and a layered structure in which the layers are stacked is formed to reduce the generation of friction by the flat surface of the layered configuration. However, since the graphite of the layered structure has an open boundary, and the carbon atoms arranged at the boundary are relatively active and highly active, when the graphite is used in an oxygen-containing environment higher than 325 ° C, the boundary carbon atom system easily interacts with oxygen. Oxidation generates carbon dioxide, so that the surface structure of the graphite changes and the lubrication effect is lost. Therefore, the graphite may be dispersed, cracked or even collapsed from the edge, thereby reducing the use time of the graphite.
此外，不論是二硫化鉬或二硫化鎢皆容易在高溫環境下與氧反應而生成硫，故當硫與水氣反應產生硫酸時，便可能會侵蝕機械內的金屬物件及油封，進而造成機械的損毀。縱使以耐高溫的聚四氟乙烯作為添加劑，亦可能在高於400℃的環境作用下，因聚四氟乙烯持續受熱而產生膠化成膜之現象，故當聚四氟乙烯添加於汽缸內，則會於汽缸壁上附著膠化後的鐵氟龍薄膜，而在活塞反覆刮刷時造成鐵氟龍的剝落，嚴重阻塞機械而造成不良影響。In addition, both molybdenum disulfide or tungsten disulfide can easily react with oxygen in a high temperature environment to form sulfur. When sulfur reacts with water vapor to produce sulfuric acid, it may corrode metal objects and oil seals in the machine, thereby causing machinery. Damaged. Even with high temperature resistant PTFE as an additive, it is possible to produce a gelatinized film due to the continuous heating of polytetrafluoroethylene under the action of an environment higher than 400 ° C. Therefore, when PTFE is added to the cylinder, The glued Teflon film is attached to the cylinder wall, and the Teflon peels off when the piston repeatedly scrapes, which seriously blocks the machine and causes adverse effects.

承上，本發明潤滑油添加劑係以奈米碳球及奈米氮化鋁球作為主要成分，以透過奈米碳球具有之形狀優異性、高熱傳導度、可掃除自由基及填補縫隙等特性，以及奈米氮化鋁球之形狀延展性、高熱高壓具液態金屬及填補縫隙等特性進而提升該潤滑油添加劑的實用優勢。詳言之，由於奈米碳球是由多層石墨層以球中球的結構所組成之多面體碳簇，故在其內面堆疊有層層的球形殼層，每一殼層的結構皆相似於多面穹頂(geodesic dome)，進而構成整體封閉且無邊界之奈米球體。如此一來，因奈米碳球於外在構型上並沒有暴露之邊界，故其中碳原子的躍動顯得較為穩定且具有較佳化學安定性，以能降低高溫環境下所產生之氧化作用，進而維持奈米碳球的表面結構，以使該潤滑油添加劑發揮較佳之潤滑效果；甚至，藉由奈米碳球的滾動不僅能降低機件間的相互摩擦，更可以使該奈 米碳球披覆並填補於金屬表面之縫隙中，進而形成潤滑表層，以大量減少機件摩擦的熱能產生，相對降低機件因溫度變化所可能導致之嚴重耗損。而奈米氮化鋁球經特殊之工藝方法製備，當引擎在高溫高壓的狀態下，奈米氮化鋁球被滲嵌到金屬表面凹痕和微孔中並牢固地抓住引擎金屬內壁，藉由液態金屬之特性於引擎內部金屬表面造成類奈米陶瓷保護膜，由於這層薄膜的形成使得摩擦力大幅地降低，提高抗磨能力，增加引擎的輸出功率，達到省油的目的。According to the above, the lubricating oil additive of the present invention is mainly composed of a nano carbon sphere and a nanometer aluminum nitride sphere, and has the characteristics of shape, high thermal conductivity, sweeping free radicals and filling gaps through the nano carbon sphere. And the shape of the nano-aluminum nitride ball ductility, high heat and high pressure with liquid metal and filling gaps and other characteristics to enhance the practical advantages of the lubricant additive. In detail, since the nanocarbon sphere is a polyhedral carbon cluster composed of a multi-layered graphite layer and a spherical ball structure, a layered spherical shell layer is stacked on the inner surface thereof, and the structure of each shell layer is similar to A geodesic dome, which in turn constitutes a generally closed and borderless nanosphere. As a result, the carbon nanotubes have no exposed boundaries in the external configuration, so the carbon atoms are more stable and have better chemical stability, so as to reduce the oxidation generated in a high temperature environment. Further, the surface structure of the nanocarbon carbon sphere is maintained to make the lubricating oil additive exert a better lubricating effect; even, the rolling of the nano carbon sphere can not only reduce the mutual friction between the parts, but also make the nai The carbon carbon ball is covered and filled in the gap of the metal surface to form a lubricating surface layer, which greatly reduces the heat energy generated by the friction of the machine member, and relatively reduces the serious wear and tear caused by the temperature change of the machine member. The nano-aluminum nitride ball is prepared by a special process. When the engine is under high temperature and high pressure, the nano-aluminum nitride ball is infiltrated into the metal surface dent and micro-hole and firmly grasps the inner wall of the engine metal. The nano-ceramic protective film is formed on the metal surface of the engine by the characteristics of the liquid metal. The frictional force is greatly reduced due to the formation of the film, the anti-wear ability is improved, the output power of the engine is increased, and the fuel-saving effect is achieved.
而在奈米碳球方面，奈米碳球之石墨殼層經化學修飾後，更可呈現出較佳的親油特性，而能均勻分散於各式潤滑油之中，以當油品在高溫下與氧作用而裂解生成大量自由基時，奈米碳球便能輕易將大量自由基予以吸附，進而延長油品的穩定性及熱安定性。並且，具3D立體構型之奈米碳球更具有多方向的熱傳導性，而能提高潤滑油之熱傳導度，以及與自然熱對流之散熱效果。In the case of nanocarbon spheres, the graphite shell of the nanocarbon sphere can be chemically modified to exhibit better lipophilic properties, and can be uniformly dispersed in various lubricating oils, so that when the oil is at a high temperature When it is cleaved with oxygen to form a large amount of free radicals, the nanocarbon sphere can easily adsorb a large amount of free radicals, thereby prolonging the stability and thermal stability of the oil. Moreover, the carbon carbon sphere having a 3D configuration has multi-directional thermal conductivity, and can improve the thermal conductivity of the lubricating oil and the heat dissipation effect with natural heat convection.
除上述之外，將本發明潤滑油添加劑混合於各式潤滑油，以應用於汽、機車引擎或各式機械時，係可有效減少燃油使用量，而降低油料的耗損及污染，進而實現綠色環保能源之開發，達到節省能源耗損之功效。In addition to the above, the lubricating oil additive of the present invention is mixed with various lubricating oils for use in steam, locomotive engines or various types of machinery, which can effectively reduce the amount of fuel used, thereby reducing the consumption and pollution of the oil, thereby realizing green The development of environmentally friendly energy has achieved the effect of saving energy and loss.
為了證實本發明潤滑油添加劑具有上述功效，本實施例較佳係選擇以6%之奈米碳球及4%之奈米氮化鋁球，混合18%之黏度調整劑、32%之分散劑、27%之消泡劑及13%之油溶性有機二價金屬作為潤滑油添加劑，並將該潤滑油添加劑加入基礎油中，以形成一潤滑油，其中，該基礎油為全合成型基礎油(採購自德國Kuttenkeuler Lubricants全合成基礎油)，該潤滑油添加劑與該基礎油以重量比1：5(第A1組與第B1組)或1：4(第A2組與第B2組)的比例混合均勻，且該黏度調整劑為甲基丙烯酸酯聚合物，該分散劑為聚異丁烯系化合物，該消泡劑為矽酮系化合物， 以獲得本發明潤滑油添加劑。在此，分別於怠速與定速的模態之下作出油耗結果並顯現於表一及表二，以在不同重量之潤滑油添加劑的添加下，觀察每小時所消耗之汽油量(kg)。In order to prove that the lubricating oil additive of the present invention has the above-mentioned effects, the present embodiment preferably selects 6% carbon carbon balls and 4% nano aluminum nitride balls, and mixes 18% viscosity adjusting agent and 32% dispersing agent. 27% of a defoaming agent and 13% of an oil-soluble organic divalent metal as a lubricating oil additive, and the lubricating oil additive is added to the base oil to form a lubricating oil, wherein the base oil is a fully synthetic base oil (purchased from the German Kuttenkeuler Lubricants total synthetic base oil), the ratio of the lubricating oil additive to the base oil in a weight ratio of 1:5 (Group A1 and Group B1) or 1:4 (Group A2 and Group B2) The mixture is uniform, and the viscosity modifier is a methacrylate polymer, the dispersant is a polyisobutylene compound, and the antifoaming agent is an anthrone compound.

由表一及表二結果可知，不論在怠速或定速之模態下的平均油耗量，皆可以在添加有奈米碳球及奈米氮化鋁球之潤滑油添加劑後獲得提升。It can be seen from the results of Tables 1 and 2 that the average fuel consumption in the mode of idle speed or constant speed can be improved after adding the lubricating oil additive of nano carbon spheres and nano aluminum nitride balls.
然而，於模態測試下的平均油耗提升幅度並不顯著，故本發明另選擇以實車測試方式，以完成如表三所示之平均油耗比較表。其中，第C1組為未添加該潤滑油添加劑至基礎油所得之潤滑油；第C2組為潤滑油添加劑與基礎油以重量比1：5混合所得之潤滑油；第C3組為潤滑油添加劑與基礎油以重量比1：4混合所得之潤滑油者。並且，將不同組別的平均油耗差異程度以百分比呈現如下。However, the average fuel consumption increase under the modal test is not significant, so the present invention additionally selects the actual vehicle test mode to complete the average fuel consumption comparison table as shown in Table 3. Wherein, the C1 group is a lubricating oil obtained by adding the lubricating oil additive to the base oil; the C2 group is a lubricating oil obtained by mixing the lubricating oil additive with the base oil at a weight ratio of 1:5; the C3 group is a lubricating oil additive and The base oil is a mixture of the obtained lubricating oil at a weight ratio of 1:4.

Therefore, it is confirmed that the lubricating oil additive of the present invention can pass the excellent lubricating property, thereby reducing mutual friction between the parts, and relatively reducing the amount of fuel used, thereby reducing the effect of oil consumption and pollution, and the greater the age, the more fuel-efficient The more obvious the situation, the average maximum increase of 11.1% (B) and 23.7% (C) of driving kilometers per hour with no use of nanocarbon balls and nano-aluminum nitride balls.
