一种船用气缸油组合物及其制备方法与应用Marine cylinder oil composition and preparation method and application thereof 技术领域Technical field
本发明涉及一种船用气缸油组合物及其制备方法与应用，更确切的说是一种用于低速二冲程船用发动机缸套或活塞润滑，且能够满足硫含量为0.5-2.5％的船用燃料的使用需求的船用气缸油组合物及其制备方法与应用。The invention relates to a marine cylinder oil composition and a preparation method and application thereof, and more particularly to a low-speed two-stroke marine engine cylinder liner or piston lubrication, and can meet the marine fuel with a sulfur content of 0.5-2.5%. Marine cylinder oil composition for use and its preparation method and application.
背景技术Background technique
燃料中的硫在燃烧后生成SO2和SO3，在露点温度下与水结合后经浓缩，在气缸的燃烧室表面形成硫酸，直接导致发动机的机械部件的腐蚀磨损，对发动机的危害极大。因此，船用气缸油的重要作用之一是利用其含有的碱性物质中和掉发动机在燃烧过程中产生的酸性物质，抑制腐蚀磨损以保护发动机部件。The sulfur in the fuel generates SO 2 and SO 3 after combustion, and combines with water at the dew point temperature to concentrate, forming sulfuric acid on the combustion chamber surface of the cylinder, directly causing corrosion and wear of the mechanical parts of the engine, which is extremely harmful to the engine. . Therefore, one of the important functions of marine cylinder oil is to neutralize the acid generated by the engine during combustion by using the alkaline substance contained therein, thereby suppressing corrosion wear and protecting the engine components.
船用发动机OEM对船用油碱值的要求为：当船用燃料中硫含量高于2.5％时，推荐使用70TBN气缸油；当燃料硫含量为0.5-2.5％时，推荐使用40TBN气缸油。气缸油碱值和燃料硫含量的对应关系需要严格遵守。低碱值气缸油应用于高硫含量燃油，没有被完全中和掉的酸性物质会对发动机造成严重的腐蚀磨损；反之，高碱值气缸油应用于低硫含量燃油，“过剩”的碱性物质会造成缸壁表面抛光，形成沉积物还会进入环槽缝隙，使得活塞环无法上下移动，导致严重卡咬和拉缸。Marine engine OEM requirements for marine oil-base value are: 70TBN cylinder oil is recommended when the sulfur content of marine fuel is higher than 2.5%; 40TBN cylinder oil is recommended when the fuel sulfur content is 0.5-2.5%. The correspondence between the cylinder oil base value and the fuel sulfur content needs to be strictly observed. Low-base cylinder oils are used in high-sulfur fuels. Acids that are not completely neutralized can cause severe corrosion and wear on the engine. Conversely, high-base cylinder oils are used in low-sulfur fuels, and “excess” alkalinity. The material will cause the surface of the cylinder wall to be polished, and the deposit will also enter the gap of the ring groove, so that the piston ring cannot move up and down, resulting in serious biting and pulling the cylinder.
近些年，以提高燃烧效率为目标，船用发动机技术逐渐向大缸径和长冲程方向发展，发动机功率及燃烧室温度和压力有了显著提高。高压共轨系统及润滑油脉冲注油器也应用于船舶发动机，明显的降低了发动机的燃油和机油消耗，并且降低了污染物排放。以上新型技术应用于船舶发动机上，对油品的使用性能提出更高的要求。In recent years, with the goal of improving combustion efficiency, marine engine technology has gradually developed toward large bore and long stroke, and engine power and combustion chamber temperature and pressure have been significantly improved. The high pressure common rail system and the lubricating oil pulse oiler are also applied to the marine engine, which significantly reduces the fuel and oil consumption of the engine and reduces pollutant emissions. The above new technology is applied to the marine engine and puts forward higher requirements on the performance of the oil.
文章“40TBN船用气缸油的研制”(《石油炼制与化工》(1997年04期)提到：采用茂名石化基础油，以磺酸盐、环烷酸盐、酚盐及无灰分散剂为主剂研制出40TBN船用气缸油配方，并通过了Bolnes3DNL船用气缸油台架试验。然而Bolnes3DNL台架无论在发动机尺寸还是操作控制系统上与新型船用发动机无法相提并论，并且文献并没有提供行船试验的证明材料，因此不能完全验证产品的真实性能。The article "Development of 40TBN Marine Cylinder Oil" ("Petroleum Refining and Chemical Industry" (1997-04) mentions: using Maoming Petrochemical base oil, mainly sulfonate, naphthenate, phenate and ashless dispersant The agent developed a 40TBN marine cylinder oil formula and passed the Bolles3DNL marine cylinder oil bench test. However, the Bolles3DNL gantry cannot be compared with the new marine engine in terms of engine size and operation control system, and the literature does not provide proof of the ship test. Therefore, the true performance of the product cannot be fully verified.
文章“5040船用气缸油的研制及应用”(《石油商计》(2001,19(6))提到：研制出满足硫含量1.0％-2.5％燃料油使用需要的低速十字头二冲程船用发动机气缸油，经台架试验和使用试验证明油品具有较好的清净分散性、抗磨性和经济性，为航运系统降低运输成本提供了技术保证。但是该产品并没有使用范围并没有覆盖硫含量为 0.5-1.0％船用燃料。The article "Development and Application of 5040 Marine Cylinder Oil" ("Petroleum Business Plan" (2001, 19(6)) mentions: Develop a low-speed crosshead two-stroke marine engine that meets the needs of fuel oil with a sulfur content of 1.0%-2.5%. Cylinder oil, through bench test and use test, proves that the oil has good clean dispersibility, anti-wear and economy, and provides technical guarantee for the shipping system to reduce transportation cost. However, the product does not cover the scope and does not cover sulfur. Content is 0.5-1.0% marine fuel.
CN103374442A公开了一种船用气缸油组合物及其制造方法，该组合物包含曼尼希碱、抗磨剂、金属清净剂和润滑油基础油。应用分子单元结构适宜的曼尼希碱，生产的船用气缸油组合物具有优异的清净分散性能和防锈性能，适用于大功率低速船用十字头式柴油机气缸的润滑。该船用气缸油组合物的碱值、燃料硫含量范围和发动机台架或行船试验数据等并没有被明确提及。CN103374442A discloses a marine cylinder oil composition and a method of producing the same, the composition comprising a Mannich base, an antiwear agent, a metal detergent, and a lubricating base oil. The use of Mannich base with suitable molecular unit structure, the marine cylinder oil composition produced has excellent clean dispersing performance and anti-rust performance, and is suitable for lubricating the cylinder of high-power low-speed marine crosshead diesel engine. The base value of the marine cylinder oil composition, the range of fuel sulfur content, and engine bench or row test data are not explicitly mentioned.
目前尚无能够满足硫含量为0.5-2.5％的船用燃料的使用需求、具有优异的清净分散、抗氧化和抗磨性能，并且通过实船试验验证的40TBN气缸油产品，研发此类产品是本领域亟待解决的问题之一。At present, there is no need to meet the requirements of marine fuels with a sulfur content of 0.5-2.5%, 40BSN cylinder oil products with excellent clean dispersion, anti-oxidation and anti-wear properties, and verified by real ship test.
