全有机硬水稳定型发动机冷却液的研制

Development and optimization of hard water stabilized all-organic engine antifreezing fluid

将有机羧酸缓蚀剂、唑类化合物与聚羧酸类硬水稳定剂复配,并进行了配方优化,得到了全有机硬水稳定型发动机冷却液。该新型冷却液不仅对多种金属具有优良的保护性能,而且能够有效地改善冷却液的硬水稳定性。

The organic acid based corrosion inhibitors, azole compounds and polycarboxylic acid based hard water stabilizers were compounded and optimized as engine antifreezing fluid. The obtained formulations were defined as the hard water stabilized all - organic engine antifreezing fluids, which not only have excellent multi -metal protection performances, but can effectively improve the hard waterstability of antifreezing fluid.
