Description

气体发动机油组合物及其用途
技术领域
本发明涉及一种气体发动机油组合物及其用途。
背景技术
近年来，随着我国能源结构的调整和节能减排战略的逐步实施，使用清洁气体燃料的纯气体发动机以其低的二氧化碳排放、无硫氧化物和颗粒物排放的优势，开始越来越受到关注。四冲程纯气体中速发动机主要用于各种分布式能源系统、船舶主(副)机、陆用电站、移动电站和煤层气发电等领域。
纯气体中速机相对于中速柴油机，工作温度更高，发动机油更容易发生氧化和硝化反应，生产酸性物质和沉积物；气体燃料硫含量极低，为防止出现碱值过剩现象，要求气体机油具备良好的清净性的同时，碱值较低；由于纯气体发动机点燃方式为火花塞直接点燃，为了保护发动机气阀及火花塞，要求气体发动机油硫酸盐灰分较低。
发明内容
本发明涉及一种气体发动机油组合物。所述气体发动机油组合物，以重量份数计由以下组份组成：
a)1～10份清净剂，所述清净剂选自水盐酸盐、磺酸盐或硫化烷基酚盐中的至少一种；
b)1～10份分散剂，所述分散剂选自高分子无灰分散剂、丁二酰亚胺分散剂或硼化无灰分散剂中的至少一种；
c)1～25份抗氧剂，所述抗氧剂选自硫磷型锌盐、胺型抗氧剂、酚型抗氧剂、噻吩型抗氧剂或氨基甲酸盐类抗氧剂中的至少一种；
d)0.05～1份降凝剂，所述降凝剂选自聚α烯烃或聚甲基丙烯酸酯的至少一种；
e)0.01～1份抗泡剂，所述抗泡剂选自甲基硅油或氟硅油抗泡剂中的至少一种；
f)60～95份基础油，所述基础油选自HVIⅠ类基础油或Ⅱ类基础油中的至少一种。
根据本发明的一个方面，以重量份数计，组份a)的用量为1～8份，组份b)的用量为1～8份，组份c)的用量为1～20份，组份d)的用量为0.1～0.5份，组份e)的用量为0.05～0.5份，组份f)的用量为70～95份。
根据本发明的一个方面，组份a)为水杨酸盐、磺酸盐和硫化烷基酚盐的混合物；所述混合物中水杨酸盐与硫化烷基酚盐的重量比为0.5～2.0，磺酸盐和硫化烷基酚盐的重量比为0.2～3.5。
根据本发明的一个方面，组份b)为高分子无灰分散剂和丁二酰亚胺分散剂的混合物，或者为硼化无灰分散剂与丁二酰亚胺分散剂的混合物。
根据本发明的一个方面，所述组合物中钙与镁总含量不大于3000ppm，优选不大于2300ppm，更优选不大于2000ppm；且氮含量不小于800ppm，优选不小于1300ppm，更优选不小于1600ppm。
本发明气体发动机油组合物的制备方法为：将各组份按比例在50～70℃温度下加入基础油中，搅拌0.5～3小时，使其全部溶解，即可得到本发明的组合物。
本发明气体发动机油组合物用于纯气体中速发动机的润滑。
本发明组合物中的钙与镁主要来自清净剂，氮含量主要来自分散剂、抗氧剂和基础油，通过各组份的协同作用，特别是控制组合物中钙与镁总含量不大于3000ppm，氮含量不小于800ppm，具备优越的抗氧化性能及优越的高温清净性。
下面通过实施例对本发明作进一步阐述。
具体实施方式
【实施例1～6】
将原料各组份调制各配方进行实验，各配方组成见表1。在60℃温度下将以上混合物加热搅拌1小时至完全均匀。
采用氧化诱导期PDSC试验(SH/T 0719)考察油品的抗氧化性能，时间越长表示抗氧性越好；采用曲轴箱模拟试验(SH/T 0300)考察油品的高温清净性，成焦量越少，表明油品高温清净性越好。
各配方试验具体结果见表2。
【对比例4】
同【实施例4】，只是还增加3份稠化剂聚异丁烯。试验结果见表2。
【对比例5】
同【实施例4】，只是清净剂仅仅为磺酸盐和硫化烷基酚盐的混合物，二者的比例为0.16。试验结果见表2。
