Abstract

The invention relates to braking fluid for a motor vehicle and a preparation method of the braking fluid, particularly to braking fluid suitable for a hydraulic braking system of the motor vehicle and a preparation method of the braking fluid. The preparation method comprises the following steps: adding glycol ethers, diethylene glycol and F600 polyether proportionally, mixing and stirring uniformly, measuring the moisture content, when the moisture content is more than 0.1%, heating and carrying out vacuum dehydration until the moisture content is less than or equal to 0.1%, and obtaining solvent; and cooling the solvent to 70-80 DEG C, adding an antirusting agent, stirring and carrying out heat preservation for 1.5-2h, continuing cooling to below 60DEG C, sequentially adding benzotriazole, derivatives of benzotriazole, sodium molybdate, sodium nitrite, an antioxidant and a pH regulator, stirring for 1-2h, filtering and packaging, and obtaining a product of the braking fluid for the motor vehicle. All indexes of the braking fluid for the motor vehicle prepared by the invention reach or are higher than the V3 standard in QC / T670-2000, and a moisture content index and the effects of anticorrosion and rust protection are highlighted; the braking fluid provided by the invention is suitable for the hydraulic braking systems of all models of imported and domestic cars, passenger cars and other motor vehicles; and the braking fluid and the preparation method, provided by the invention, are simple in process and remarkable in economic effects, and are suitable for industrial production.

Description

technical field [0001] The invention relates to a motor vehicle brake fluid and a preparation method thereof, in particular to a motor vehicle brake fluid suitable for a motor vehicle hydraulic braking system and a preparation 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 our national economy. my country has become a veritable motor vehicle production and sales country in the world. [0003] In recent years, the development of my country's automobile industry has gradually approached the international level. The main European models, Japanese models, and American models have been jointly produced in my country. At the same time, the index requirements and test items of my country's brake fluid standard GB 12981 have shown in...
