Abstract

The invention relates to the technical field of automobile brake fluids, particularly a motor vehicle brake fluid and a production method thereof. The motor vehicle brake fluid is prepared from the following raw materials in parts by weight: 20-40 parts of diethylene glycol methyl ether, 10-25 parts of diethylene glycol, 8-12 parts of triethanolamine, 10-15 parts of triethylene glycol monomethyl ether, 6-10 parts of tributyl phosphate, 5-12 parts of boric acid, 4-6 parts of polyethyleneglycol, 5-7 parts of tributyl amine, 5-8 parts of sebacic acid and 8-16 parts of epoxypropane. The motor vehicle brake fluid has the advantages of simple manufacturing process, low volatility, favorable low-temperature fluidity and excellent high-temperature air resistance.

Description

technical field [0001] The invention relates to the technical field of automobile brake fluid, in particular to a motor vehicle brake fluid and a production method thereof. Background technique [0002] Over the past 30 years of reform and opening up, my country's economy has made remarkable achievements. The automobile industry, especially the automobile industry, has developed rapidly. The automobile industry has quickly become the pillar industry of my country's national economy. my country has become a veritable motor vehicle production and sales country in the world. [0003] Brake fluid is the working medium for transmitting pressure in hydraulic transmission, and its performance is directly related to the safety of people's lives and property. Therefore, the country has strict requirements on the quality of automobile brake fluid. In recent years, the development of my country's automobile industry has gradually approached the international level. The main European m...
