Description

一种船用气缸油复合剂
技术领域
本发明涉及一种润滑油复合剂配方，更确切的说是一种应用于船载BOB系统的气缸油专用复合剂。
背景技术
目前，在远洋船舶上安装的BOB在线调合系统(Blender-on-Boardsystem)，是将船用系统油与BOB系统专用气缸油复合剂通过自动控制系统，调制成任意目标碱值的气缸油，并能够快速的切换到发动机上使用，以适应不同硫含量燃料对不同碱值气缸油的需要。
BOB系统的工作流程是：从油箱中泵送到发动机各个润滑点进行润滑的系统油，在完成润滑后又回到油箱中，其中一部分润滑油通过侧线采出，与气缸油复合剂通过BOB系统调合成所需碱值的气缸油，气缸油完成润滑后烧掉，残留物流入油泥箱中。
针对BOB系统这种新型的气缸油在线调和工艺，复合剂的开发必须适应在线配制与基础油的配伍性问题，协调气缸油与系统油的性能平衡，保证复合剂具有较为广泛的适用性，能够满足船用发动机的使用需要。
通过对国内、外相关专利进行查新，尚未检索到船载BOB在线调和系统及BOB系统专用复合剂的相关文献。
发明内容
本发明的目的在于提供一种满足船用BOB系统在线调和要求，具有广泛适应性的船用气缸油复合剂。
本发明所述的一种船用气缸油复合剂，其特征在于它的组分及含量按重量百分比为：超高碱值磺酸盐清净剂15-25％、超高碱值酚盐清净剂35-45％、超高碱值环烷酸盐清净剂10-30％、分散剂0-8％、抗磨剂0-4％、高粘度指数I类基础油400SN/500SN/650SN 10-20％。
所述的超高碱值磺酸盐为：长链(C22-30)线型烷基苯超高碱值磺酸钙，碱值为395-430mgKOH/g。
所述的超高碱值硫化烷基酚盐为：长链烷基(C18-24)硫化酚钙，碱值为290-310mgKOH/g。
所述的超高碱值环烷酸盐为：超高碱值长链(C20-30)环烷酸盐清净剂，碱值为390-420mgKOH/g。
所述的分散剂为：单聚异丁烯丁二酰亚胺、双聚异丁烯丁二酰亚胺或者多聚异丁烯丁二酰亚胺。
所述的抗磨剂为：长链(C12-18)伯醇基硫代磷酸锌或者长链(C12-16)仲醇基硫代磷酸锌。
所述的基础油为：高粘度指数I类基础油400SN/500SN/650SN 10-20％，100℃的运动粘度为8.0-11.0cst；。
本发明提供的船用气缸油复合剂选用了三种清净剂，其中：超高碱值磺酸盐清净剂具有优异的清净分散性能，但是抗磨性能和抗氧化性能较差；硫化烷基酚钙具有优异的抗磨性能和抗氧化性能，但是清净分散性能较差；环烷酸盐的油膜扩散性能较好，但是清净性能和抗磨性能较差，将三种清净剂进行复配，既能兼有三种清净剂的优点，同时还弥补了各自性能的不足。
本发明的特点是：该复合剂满足BOB系统工艺对其黏度和碱值要求，能够在线调制，适应范围广，与国内、外各种型号和品牌的系统油混合调制成不同碱值气缸油，在抗磨性、抗氧化性能和高温清净性方面性能优异，满足船用发动机的性能要求；该复合剂具有良好的溶解稳定性和配伍性，不会影响到气缸油的润滑性能。该复合剂已经通过4000小时行船试验，获得船用发动机OEM(设备原制造商)——MAN B&W的技术认证。
