Abstract

The invention relates to the technical field of automobile brake fluid, and discloses borate type automobile brake fluid which is prepared from the following raw materials in parts by weight: 60-70 parts of propylene glycol monomethyl ether borate, 3-7 parts of silicone oil, 10-40 parts of polyethylene glycol monoalkyl ether, 75-85 parts of triethylene glycol monomethyl ether borate, 0.2-0.8 partof 6-methyl-2-mercaptobenzothiazole, 0.5-0.9 part of an antioxidant; 1-3 parts of an alkalinity regulator, 1-3 parts of a corrosion inhibitor and 0.1-0.3 part of a metal preservative. According to theborate type automobile brake fluid, the brake fluid is prepared from borate, the production cost of the brake fluid is effectively reduced, industrial production is facilitated, the product quality meets the GB12981-2012HZY6 standard requirement, and the borate type automobile brake fluid not only has high dry and wet boiling points, but also has good low-temperature kinematic viscosity, and canmeet the requirements that the dry boiling point is greater than 270 DEG C and the wet boiling point is greater than 190 DEG C; the technical requirement that the low-temperature kinematic viscosity is not higher than 650 mm < 2 >/s is met, and meanwhile, the experimental requirement of 240-hour long-term metal corrosion resistance specified by the standard can be met.

Description

technical field [0001] The invention relates to the technical field of automobile brake fluid, in particular to a borate type automobile brake fluid. Background technique [0002] There are three types of brake fluid. When purchasing, choose a reliable manufacturer, and the higher the level, the better. Its braking pressure is generally 2MPa, and the highest can reach 4-5MPa. All liquids are incompressible. In a sealed container or a pipeline filled with liquid, when the liquid is under pressure, the pressure will be quickly and evenly transmitted to all parts of the liquid. Hydraulic brakes use this principle to work. [0003] Most of the brake fluids used in the automobile market are alcohol ether synthetic type and borate type. Generally, medium and high-end cars mostly use borate type brake fluid. Borate brake fluid technology has become a high-performance brake fluid technology. Technology is required. Therefore, the research and synthesis of high-performance borat...
