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, feed in nitrogen, raise the temperature to 100°C, stir, add 46kg of metal sodium chips in batches, and drop 198kg of 1,1-dichloroethane, 2 The dropwise addition was completed within 1 hour, kept at 100°C for 2 hours, distilled out cyclohexane, cooled to room temperature, press-filtered, added 100kg of deionized water to the filtrate, stirred at room temperature for 20 minutes to obtain material A, and passed material A through 732 cation exchange resin bed, 717 Anion exchange resin bed, anion-cation mixed ion exchange resin bed, wherein the mass ratio of anion exchange resin 717 to cation exchange resin 732 in the anion-cation mixed ion exchange resin bed is 1:1. Material B was obtained by flowing out the material liquid, and the conductivity of material B was detected to be 2.1μScm -1 , Chloride <1.2ppm. Put material B into a v...

Abstract

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

Description

1. Technical field: [0001] The invention relates to the preparation of the main raw material polymer mixture of the motor vehicle brake fluid suitable for the hydraulic braking system of the motor vehicle, the formula of the motor vehicle brake fluid and its production method. 2. Background technology: [0002] Motor vehicle brake fluid is an important part of the car braking system. With the development of expressways in our country, automobiles brake more frequently when driving at high speed, and a large amount of frictional heat will inevitably cause the temperature of the braking system to rise. The original brake fluid of motor vehicles in my country cannot meet modern requirements. In order to ensure the safety and reliability of the braking system, the National Bureau of Quality and Technical Supervision issued the national standard GB10830-1998 of the People's Republic of China on September 16, 1998, and the National Bureau of Machinery Industry issued the Automobil...
