Problems solved by technology

The above patents and some borate brake fluids on the market have the following problems to varying degrees: the selected dialkyl ether contains tert-butyl ether or dibutyl ether, poor water capacity, and large rubber expansion , The boric acid ester in the brake fluid is sensitive to water. When storing or absorbing water, it is easy to precipitate sediment, which brings the hidden danger of unsafe braking.

Abstract

The invention relates to alcohol ether borate brake fluid. The alcohol ether borate brake fluid is prepared from the following raw materials in percentage by weight: 20-50% of triethylene glycol monomethyl ether borate, 10-45% of polyglycol monobutyl ether borate with the number-average molecular weight being 780, 10-40% of polyglycol monoether, 10-40% of multiethylene-glycol, 0-15% of triethylene glycol dimethyl ether, 0-3% of an antioxidant, 0-5% of a pH value adjusting agent, and 0-5% of a corrosion resister. According to the alcohol ether borate brake fluid disclosed by the invention, the problem that conventional alcohol ether borate brake fluid is unstable is solved, and the alcohol ether borate brake fluid has the following advantages of being high in resistance for air resistance, good in low-temperature fluidity, rustproof, anti-corrosion, good in adaptability to rubber parts and excellent in heat stability.

Description

technical field [0001] The invention relates to an alcohol ether borate type brake fluid, in particular to an alcohol ether borate type brake fluid comprising triethylene glycol monomethyl ether borate and polyethylene glycol monobutyl ether borate liquid. Background technique [0002] Automobile brake fluid is commonly known as brake oil. Adding brake fluid to automobile brakes is based on the famous Pascal's principle: when pressure is applied to the liquid, the pressure transmitted by the liquid in all directions is equal. By applying pressure to the brake fluid of the car, the main pump and the slave pump interact to the piston of the brake pump, and then apply it to the brake shoe (caliper) to achieve car braking. With the rapid development of the automobile industry in the past two decades, the technology of automobile braking systems has also been greatly improved. The use of anti-lock brakes (ABS) and four-wheel braking electronic balance stabilization system (ESP) ...
