Description

一种发动机清洁剂及其制备方法
技术领域
本发明属于发动机清洁剂制备领域，尤其涉及一种发动机清洁剂及其制备方法。
背景技术
车辆行驶中，因为燃油中的胶质和燃烧后形成的积碳引起故障是比较常见的，而且危害极大。长时间不对进气系统和喷油嘴及气缸内进行清洗，会使发动机进气受阻和喷油雾化不良及喷油不均，小颗粒积碳在气缸内会对活塞、气缸套及活塞环加快磨损，严重者会堵塞三元催化器，造成发动机爆震，发动机工作不良，并增加油耗及造成尾气排放超标。而汽缸盖部位产生积碳后，会降低发动机的冷却效果。使发动机的动力性和经济性都大大降低。活塞顶部积碳，会形成许多炽热面，引起早燃和爆震，造成点火提前角滞后，引起汽缸内燃烧不完全，发动机无力，机体发热等，从而缩短发动机的使用寿命。
但现有的发动机清洗剂存在着以下缺点与不足：着车清洗的清洗效果差，需要多次重复清洗及较长时间清洗才能达到较好的清洗效果，清洗时间长，费用高。
因此，提出一种发动机清洁剂及其制备方法，具有良好的清洗效果。
发明内容
为了解决上述技术问题，本发明提供一种发动机清洁剂，该发动机清洁剂由以下重量份组成：基础油150N 70-90％、烷基苯5-20％、降凝剂0.1-0.4％、抗磨剂0.2-0.8％、清净剂1-3％、分散剂1-3％、增粘剂5-10％、消泡剂50-200ppm。
优选的，所述降凝剂为聚甲基丙烯酸酯降凝剂。
优选的，所述抗磨剂为丁辛基ZDDP或双丁辛基ZDDP其中一种。
优选的，所述清净剂为低碱值石油磺酸钙或低碱值合成磺酸钙其中一种。
优选的，所述分散剂为双丁二酰亚胺或单丁二酰亚胺其中一种。
优选的，所述增粘剂为聚异丁烯或二元乙丙胶溶液其中一种。
优选的，所述消泡剂为2号复合消泡剂。
优选的，该方法步骤为：
步骤1：首先打开调和釜外置循环泵，加入上述重量份的基础油150N、烷基苯，对基础油150N、烷基苯进行搅拌，并升温至55±5℃，搅拌完成后取样，进行底油粘度检验；
步骤2：待底油粘度检验合格后，先向调和釜外置循环泵投入消泡剂，再投入降凝剂，之后投入增粘剂；最后在依次投入清净剂、分散剂和抗磨剂，投料完毕，打开调和釜外置循环泵进行搅拌，循环搅拌30min,完成调和，取样送检。
优选的，所述调和釜外置循环泵的搅拌速率为40r/min。
与现有技术相比，本发明的有益效果为：
1.本发明具有超强的溶解能力，能够溶解发动机油润滑系统残留的油泥、积碳以及其余机械杂质。
2.本发明具有优异的低温分散能力，能够将溶解下来污染物，以胶体或胶束的形式，均匀的分散在清洁剂中排出。
3.本发明具有一定的碱性，能够中和发动机润滑系统残留的酸性物质，延长下次更换油品的使用寿命，避免酸性物质对下次保养加入油品污染。
4.本发明的油品的抗磨性能强，且油膜强度适宜，能够为发动机清洁过程提供更好的保护。
