发明名称 | Brake fluid composition comprising triazole and thiadiazole | ||
摘要 | The present invention relates to a brake fluid composition comprising a glycol compound as a solvent, and triazole, thiadiazole mixture, and antioxidant as metallic corrosion inhibitors. Provided is a brake fluid composition having improved long-term metallic and high-temperature corrosion inhibition. The brake fluid composition according to the present invention significantly improves long-term durability by being a superior anti-corrosive as well as having a reduced weight variation on a test piece, and has a superior high-temperature corrosion inhibition while having negligible effects on the equilibrium reflux boiling point and the wet equilibrium reflux boiling point. | ||

主权项 | 1. A brake fluid composition comprising: 85 to 99 wt %, based on the total weight of the composition, of a glycol compound as a solvent; 0.5 to 10 wt %, based on the total weight of the composition, of a mixture of triazole and thiadiazole, and 0.1-5.0 wt %, based on the total weight of the composition, of an amine compound as a metal corrosion inhibitor; and 0.1-5.0 wt %, based on the total weight of the composition, of an antioxidant; wherein the glycol compound as the solvent is comprised of 5.0-30 wt % of polyalkylene glycol and 70-85 wt % of glycol ether, based on the total weight of the solvent, wherein the glycol ether is one or more selected from the group consisting of polyethylene glycol mono-methyl ether, polyethylene glycol mono-butyl ether and triethylene glycol mono-methyl ether;wherein the triazole is benzotriazole or tolyltriazole;wherein the thiadiazole is 2,5-dimercapto-1,3,4-thiadiazole;wherein the amine compound are two species selected from a group consisting of alkyl diethanol amine, cyclohexyl amine and triethanol amine; andwherein the antioxidant is dibutyl hydroxy toluene. | ||
