Abstract
本发明涉及一种航空燃料抗磨剂及其应用，以重量份计，包括桐油二聚酸：10‑20份；非桐油植物油二聚酸：45‑60份；抗氧剂：0.5‑5份；溶剂：20‑25份。本发明抗磨剂用于航空燃料时，综合使用性能优异，具有良好的抗磨性和防锈蚀能力。
Description
技术领域
本发明属于航空燃料抗磨剂领域，具体涉及一种航空燃料抗磨剂及其应用。
背景技术
随着环保法规对发动机排放的要求不断苛刻，航空燃料在生产过程中主要采用酸碱精制、加氢精制或加氢裂化，使得馏分中的天然抗磨成分硫和芳烃等被脱除，导致航空燃料抗磨性降低，可能会引起燃油泵柱塞球面超量磨损，导致供油量不足，严重时会引起空中停车等事故。在喷气发动机中，燃油泵的润滑是依靠喷气燃料自身的润滑性能来保障的，燃油系统部件特别是旋转和摆动部件的工作寿命很大程度上取决于喷气燃料的润滑性能。因此，需要在航空燃料中加入抗磨剂，防止燃料系统的严重磨损。
目前，国内航空燃料中加入的抗磨剂是T1602，T1602的有效组分是环烷酸，环烷酸的加入会导致航空燃料的酸度增大，还会导致喷气燃料的腐蚀性增大。此外，环烷酸是石油中的天然有机酸，在石油中的含量为0.03～5.0%，由于分离工艺为碱洗-酸化-蒸馏精制，工艺过程产生大量废水，污染环境，国外已陆续停止使用。
US5630852公开了一种有机磷酸酯航空燃料抗磨剂，其酸值最小为1.0mgKOH/g。该抗磨剂在50ppm以上的使用量下才可以满足抗磨性要求。另外，参考Ministry ofDefenceStandard 68-251，Fuel soluble lubricity improving additives for aviationturbine fuels(NATO Code: S-1747)，要求不含有磷成分。
目前，国外普遍采用环保型二聚酸及其衍生物作为航煤的抗磨剂，如InnospecDCI-4A/DCI-6A、Nalco 5403/5405等牌号抗磨剂。二聚酸来源于生物基脂肪酸，经聚合后得到二聚酸及多聚酸的混合物，通过复配后可用于航煤抗磨剂，生产过程绿色环保。
CN104845685A、CN104804782A等公开了一种航空燃料的抗磨剂，包括C36不饱和脂肪酸二聚物，该C36不饱和脂肪酸二聚物包括：通式(1)所示的化合物65%以上，通式(2)所示的化合物25-30%，通式(3)所示的化合物低于10%，以质量计。制备方法包括：(A)混合脂肪酸的制备；(B)C36不饱和脂肪酸二聚物的合成，包括以亚油酸或步骤(A)所得的混合脂肪酸作为原料置于高压反应釜内，再加入9-15%的催化剂和0.5-1.5%的助剂，基于亚油酸或上述混合脂肪酸的质量计，安装好高压釜，并检验气密性，其中催化剂为活化白土，助剂为碳酸锂，催化剂的使用量优选10-13%，助剂的使用量优选0.8-1.2%。其中通式（1）、（2）、（3）都属于二聚酸的同分异构体，该剂加入加氢工艺生产的3号喷气燃料中应符合下列指标（加入量15～23mg/L），润滑性：磨斑直径(WSD)小于0.65mm，(SH/T0687)典型值0.59mm；水分离指数：MSEP≥75，(SH/T0616)典型值85～95。参照标准MIL-PRF-25017H Lubricity improver，fuelsoluble(NATO S-1747)，此抗磨剂在使用过程中存在防锈蚀能力不达标问题。
发明内容
针对现有技术的不足，本发明提供了一种航空燃料抗磨剂及其应用。本发明抗磨剂用于航空燃料时，综合使用性能优异，具有良好的抗磨性和防锈蚀能力。
本发明航空燃料抗磨剂，以重量份计，包括：
桐油二聚酸：10-20份；
非桐油植物油二聚酸：45-60份；
抗氧剂：0.5-5份；
溶剂：20-25份。
本发明中，所述的非桐油植物油二聚酸为棉籽油二聚酸、大豆油二聚酸、米糠油二聚酸、菜籽油二聚酸、花生油二聚酸等中的至少一种。所述的棉籽油二聚酸、大豆油二聚酸、米槺油二聚酸、菜籽油二聚酸、花生油二聚酸等是以棉油酸、大豆油酸、米糠油酸、菜籽油酸、花生油酸等为原料聚合制备的二聚酸，同时包含有无环、单环和双环结构，其中单环结构的含量低于60%，进一步的无环结构的含量高于20%。
本发明中，所述的桐油二聚酸是以桐油酸为原料制备的二聚酸，去除未反应的单酸，其中单环结构的含量高于70%，进一步的无环结构的含量低于10%。具体可以采用CN109879745A、CN109880532A等所述制备方法。进一步的，将桐油酸经分子蒸馏进行提纯，收集轻组分，去除杂质，然后再进行二聚酸制备。
本发明中，所述的抗氧剂为对苯二酚、甲基对苯二酚、叔丁基对苯二酚、2,6-二叔丁基-4-甲基苯酚等中的至少一种。
本发明中，所述的溶剂为航空燃料、二甲苯、乙基苯等中的至少一种，二甲苯可以是邻、间、对同分异构体中的至少一种。
本发明所述航空燃料抗磨剂的应用，当添加量为9-20mg/L，添加后航空燃料磨痕直径≯0.65mm。
本发明提供的航空燃料抗磨剂同时包含桐油二聚酸和非桐油植物油二聚酸，抗磨剂综合性能符合MIL-PRF-25017H标准，兼具良好的抗磨性和抗锈蚀性能，各项性能指标均符合标准要求。由于桐油二聚酸中单环结构的含量高于70%，非桐油植物油二聚酸中单环结构的含量低于60%，通过二者组合在保证抗磨性的同时能够避免出现防锈蚀能力不达标的风险，具有突出的防锈蚀能力。
