Background technology
Motor vehicle brake fluid is to be used for transmitting the functional liquid of braking energy in automobile liquid pressure type braking system, performance and
Quality condition is directly related to the driving safety of vehicle.Since early 1930s, automobile began to use brake fluid, vapour
Vehicle brake fluid can be divided into three types according to the difference of its raw materials for production：Alcohol type, mineral oil origin and Synthetic Brake Fluid.Alcohol
Type, mineral oil origin brake fluid are eliminated already because of its low boiling point, solidification point height, and Synthetic Brake Fluid is widely used.Synthesis type
Brake fluid mainly has 3 classes, respectively alcohol ether type, borate and silicone oil type again.Wherein silicone oil type is since its price is alcohol ether type
2-3 times and its cannot meet motor vehicle brake fluid over-all properties require and so that its development is restricted.Therefore, main exploitation at present
, it is most practical be alcohol ether type and borate brake fluid.Motor vehicle brake fluid is the pressure transmission medium in hydraulic drive, property
The quality of energy is directly related to traffic safety.There are strict requirements (GB+12981-2003) in country to the quality of motor vehicle brake fluid,
It is mainly concerned with the high temperature of brake fluid and resists gas barrier, low temperature flow, the swellability to rubber, resist metal corrosion, antioxygen
The property changed, stability etc..DOT4 requires ERBP to be not less than 230 DEG C in standard, kinematic viscosity when WERBP is not less than 155 DEG C, -40 DEG C
No more than 1800.Currently, domestic brake fluid is mostly alcohol ether type, the characteristics of this brake fluid is at low cost, but water-resistance pole
Difference, equilibrium reflux boiling point are relatively low.
