Problems solved by technology

With the development of expressways in our country, cars brake more frequently when driving at high speed, and a large amount of frictional heat will inevitably cause the temperature of the brake system to rise. The original motor vehicle brake fluid in my country cannot meet modern requirements.

Embodiment 1

[0060] Preparation of polymer mixture

[0061] Take 430kg of diethylene glycol, 100Kg of cyclohexane, and 10kg of activated carbon into the reactor, add nitrogen gas, raise the temperature to 100°C, stir, add 46kg of metal sodium scraps in batches, and add 198kg of 1,1-dichloroethane, 2 After hours of dripping, keep at 100°C for 2 hours, distill off cyclohexane, cool to room temperature, press filter, add 100kg of non-ionized water to the filtrate, stir for 20 minutes at room temperature to obtain material A, and pass material A through 732 cation exchange resin bed, 717 in turn Anion exchange resin bed and anion-cation mixed ion exchange resin bed, wherein the mass ratio of anion exchange resin 717 and cation exchange resin 732 in the anion-cation mixed ion exchange resin bed is 1:1. Material B is obtained from the outflow of material liquid, and the conductivity of material B is 2.1μScm. -1 , Chloride ion <1.2ppm. Add material B into a vacuum distillation kettle and distill off ...

Abstract

A brake liquid for the hydraulic brake system of motor-driven vehicle is prepared through preparing polymer mixture by catalytic reaction between biethanediol and 1,1-dichlorethane, adding triethanediol monoethylether borate, triethanediol monomethyl ether, diethanediol monobutylether, diethanediol monoethylether, diethanediol monomethylether and additive, stirring, dissolving, vacuum processing and filtering. It features high properties.

Description

1. Technical Field: [0001] The invention relates to a preparation of a polymer mixture of main raw materials of a motor vehicle brake fluid suitable for a motor vehicle hydraulic brake system, a motor vehicle brake fluid formula and a production method thereof. 2. Background technology: [0002] Motor vehicle brake fluid is an important part of the automobile brake system. With the development of highways in our country, cars brake frequently at high speeds, and a large amount of frictional heat will inevitably cause the temperature of the brake system to rise. my country's original motor vehicle brake fluid cannot meet modern requirements. In order to ensure the safety and reliability of the brake system, the National Bureau of Quality and Technical Supervision issued the National Standard of the People’s Republic of China GB10830-1998 on September 16, 1998, and the State Administration of Machinery Industry on December 07, 2000, issued the automotive industry of the People’s Re...
