Description

一种发动机冷却液用缓蚀剂
技术领域
本发明属于发动机冷却技术领域，具体涉及一种发动机冷却液用缓蚀剂。
背景技术
冷却液，又称防冻液、抗冻液等，汽车循环冷却系统的冷却介质，主要功能为保护发动机正常良好运行，随着汽车工业的发展，对发动机的性能要求也越来越高，不仅要求冷却液具有较低的冰点和较高的沸点，还应具有较好的金属防腐性、防气蚀性、防结垢性，且有较长的使用寿命等等方面的综合性能。据国内有关资料报导，在正常使用的汽车发动机的维修工作中，有6%是发动机冷却系统出现故障，而故障的主要原因是水垢和金属部件被腐蚀，由此可见水垢和金属部件的腐蚀对发动机水冷系统的危害有多大。市场上的冷却液中的乙二醇、丙三醇等容易生成酸性物质，腐蚀冷却系统的金属件。
发明内容
针对现有技术的不足，本发明提供一种发动机冷却液用缓蚀剂，对发动机冷却液起到很好的缓蚀作用，防止冷却液腐蚀发动机冷却系统的金属件。
本发明的技术方案是：一种发动机冷却液用缓蚀剂，由以下重量份数的原料组成：乙二醇30-40份、丙三醇10-15份、聚丙烯酰胺30-40份、硅酸钠10-15份、乙二胺四甲叉膦酸钠2-3份、氯化铜1-5份、癸二酸0.5-1份、苯甲酸0.05-0.1份、月桂酸0.05-0.1份、二乙烯三胺0.1-0.5份、8-羟基喹啉0.1-0.5份、2-巯基苯并噻唑0.05-0.08份、十二烷基苯磺酸钠2-5份。
与现有技术相比，本发明优点在于：对发动机冷却液起到很好的缓蚀作用，防止冷却液腐蚀发动机冷却系统的金属件。
