Abstract

The invention relates to the technical field of brake fluid production, and discloses an efficient borate type brake fluid and a preparation method thereof, and the preparation method comprises the following production steps: (1) synthesizing an esterification fluid, (2) blending a base fluid, and (3) preparing the efficient borate type brake fluid. According to the efficient borate type brake fluid and the preparation method thereof, the produced efficient borate type brake fluid takes a polyalcohol ether as a diluent, the borate and the polyalcohol ether are combined, the reasonable mass percent is adopted, the consumption of the borate is reduced, the cost is reduced, nitrogen atoms are introduced into the molecular structure of the borate, and a stable six-membered ring internal ligandis formed; on the basis of improving the wear resistance and friction reduction performance, a long carbon chain is introduced into molecules, triester is formed, steric hindrance is increased, attack of water molecules is hindered, and therefore the hydrolysis resistance of the brake fluid is better improved, the problem that boric acid is likely to be separated out through water due to the toohigh content of boric acid is solved, and meanwhile it is guaranteed that the brake fluid has good high-temperature air resistance.

Description

technical field [0001] The invention relates to the technical field of brake fluid production, in particular to a high-efficiency borate-type brake fluid and a preparation method thereof. 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 a...
