Description
Technical field
The present invention relates to a kind of high-grade braking liquid for car composition, is combined more particularly, to a kind of borate type braking fluid
Thing.
Background technology
Motor vehicle brake fluid is also known as brake fluid or brake-fluid, is to be used to transmit pressure in hydraulic braking system for automobile, makes wheel
Brake realizes a kind of functional liquid of braking action.With the continuous development of automotive engineering, the structure of brake fluid system
Obtain updating with perfect with performance, the quality of brake fluid is also improving constantly.Begin to use from automobile the 1930s
Since brake fluid, three the development experience alcohol brake fluid of motor vehicle brake fluid, mineral oil origin brake fluid and Synthetic Brake Fluid masters
Want developing stage, at present, alcohol type and mineral oil origin brake fluid due to exist high temperature performance difference and with rubber cup adaptability
The shortcomings of poor, has all been eliminated, and most countries mainly use Synthetic Brake Fluid at this stage.Synthetic Brake Fluid is broadly divided into
Alcohol-ether type, ester type and the class of silicone oil type three.
Alcohol-ether type brake fluid starts to occur in the 1950s, the brake fluid have higher equilibrium reflux boiling point and
Relatively low low temperature viscosity, but the moisture easily in absorption air, cause high-temperature behavior to decline, easily produce vapour lock；Simultaneously as inhale
Water increases the corrosion that can also accelerate metal parts.
Ester type brake fluid starts to occur in early 1970s, dosage it is maximum surely belong to borate-type, basic ingredient with
Based on borate, make diluent with alcohol ether, add the allotments such as a small amount of antirust agent, lubricant and antioxidant and form.The brake fluid has
There are excellent high-temperature behavior and cryogenic property, limited amount moisture can be absorbed, to overcome atmospheric water to be congealed into brake
Free water, there is hydrophobicity again, it is non-swelling to rubber to metal non-corrosiveness to ensure that brake fluid boiling point is stable, by temperature shadow
Ring less, good weatherability, turn into the new automobile braking liquid that various countries competitively develop.Existing motor vehicle brake fluid exist compatibility,
The anti-vapour lock poor performance of antioxidant, corrosion resistance, high temperature, the problem of metal rust preventing and also poor cryogenic property.
Motor vehicle brake fluid performance quality is directly connected to traffic safety and the life security of driver.With increasing for vehicle
With the raising of speed, to brake fluid performance requirement also more and more higher, it is desirable to its adapt to various modern automobile performance requirement.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of with good compatibility, antioxidant, corrosion resistance, height
Anti- vapour lock performance of temperature etc., while also there is the high-grade braking liquid for car combination of more preferable metal rust preventing and prominent cryogenic property
Thing.
What above-mentioned purpose was realized in：A kind of high-grade braking liquid for car composition by triethylene glycol monomethyl ether borate,

Triethylene glycol monomethyl ether borate accounts for 60-73%, and dibutyl ethylene glycol ether accounts for 15-20%, polyalcohol rubber swelling
Inhibitor accounts for 10-20%, and antioxidant accounts for 0.1-1.0%, and preservative accounts for 0.1-2.0%, and antirust agent accounts for 0.2-1.0%, pH regulations
Agent accounts for 0.5-1.0%；The percentage that each raw material sum accounts for composition total weight is 100%；
The preparation method of described triethylene glycol monomethyl ether borate is：In the confined reaction with heating, decompression
Metered triethylene glycol monomethyl ether in kettle, when stirring, being warming up to 60 DEG C, boric acid is added in reactor, stir, heat up,
Depressurize (pressure is -0.09--0.1MPa), temperature control reacts 4h at 90-150 DEG C；Reaction terminate after out of kettle sampling Detection
Water content, when water content≤0.1%, qualified esterifying liquid is obtained, i.e. esterification is completed, the weight of triethylene glycol monomethyl ether and boric acid
Amount is than being 10: 1；
Manufacturing process：By triethylene glycol monomethyl ether borate, dibutyl ethylene glycol ether, polyalcohol rubber swelling inhibitor,
Antioxidant, preservative, antirust agent and pH adjusting agent are dosed in reactor by above-mentioned percentage by weight, are stirred under normal temperature and pressure
60min, it is 50r/min to be kept stirring for speed, and sampling Detection, detection are qualified out of kettle after various raw materials are sufficiently mixed dissolving
Afterwards, filter, import standby in finished pot.
Described dibutyl ethylene glycol ether is diluent.
Described polyalcohol rubber swelling inhibitor is glycerine or triethylene glycol or diethylene glycol or tetraethylene glycol.
