Problems solved by technology

Existing brake fluids are prone to air locks, which will cause the attenuation of the brake fluid storage, and will corrode the existing braking system, causing the function of the braking system to be weakened or even lost.

Abstract

The invention relates to a noncorrosive automobile brake fluid which is prepared from the following raw materials in parts by weight: 6-8 parts of hindered phenol antioxidant, 11-14 parts of diethylene glycol-methyl ether, 3-10 parts of sebacic acid, 4-9 parts of sodium benzoate, 3-5 parts of polysorbate, 8-10 parts of glycerol, 7-11 parts of lauryl sodium sulfate, 5-8 parts of 2,6-di-tert-butyl-para-cresol, 6-8 parts of nonylphenol polyethenoxy ether, 1-4 parts of tea polyphenol, 2-6 parts of lubricant, 9-14 parts of castor oil, 5-10 parts of butanol and 6-11 parts of dimethyl silicone oil. The automobile brake fluid has the advantages of favorable low-temperature fluidity, high boiling point and no corrosiveness to the braking system.

Description

technical field [0001] The invention relates to a corrosion-free automobile brake fluid. Background technique [0002] Automobile brake fluid is also called brake fluid. Early cars used mechanical brakes with drum brakes. With the development of hydraulic technology, safe and reliable hydraulic braking system is widely used in automobiles. Automobile brake fluid is the fluid used in the hydraulic braking system of automobiles. Although the mechanism of the brake system is continuously improved. But the working principle of the brake fluid in the brake system remains the same. When the driver steps on the brakes, the force from the pedals is transferred from the piston of the brake master cylinder to the sub-cylinders of the wheels through the brake fluid, so that the friction plates expand to achieve the purpose of stopping the vehicle from moving forward. The existing brake fluid is prone to air lock phenomenon, which will cause the attenuation of the brake fluid stora...
