| titleOfInvention | Preparation method of high-grade borate type automobile brake fluid |
| abstract | The invention relates to a preparation method of a high-grade borate type automobile brake fluid, which comprises a synthesis of polyxinolum and borate as well as blending of the brake fluid. The method is characterized in that n-propanol and epoxypropane are taken as raw materials, a polymerization is generated under the effect of a basic catalyst, and the high polyxinolum with 4-6polymerization degree can be obtained after decolouring, adsorbing, filtering and performing reduced pressure distillation. The method takes high polyxinolum, boric acid and 1,3-propylene glycol as raw materials to synthesize six-membered ring borate with low-viscosity by a two stages esterification method, and the dry equilibrium reflux boiling point and the hydrolytic stability of the brake fluid. The semi-polar boric acid diglyceride is synthesized, and can be used as a basic additive solution to increase the wet equilibrium reflux boiling point of the brake fluid, and can be used with glycerol to prevent the swelling of the rubber. According to the invention, the six-membered ring borate and the boric acid diglyceride are taken as basic liquids, low polyxinolum is taken as a diluent, a proper amount of additive is added, and the high-grade borate type automobile brake fluid can be blended. |
