Description

A kind of motor vehicle antifreeze fluid and preparation method thereof

Technical field:

The present invention relates to anti-icing fluid technical field, be specifically related to a kind of motor vehicle antifreeze fluid and preparation method thereof.

Background technology:

The full name of anti-icing fluid should be anti-freeze cooling liquid, mean the coolant of antifreeze function, unfrozen cooling fluid when anti-icing fluid is possible to prevent stop cold season and spalling radiator and freezing engine cylinder block, but we to correct a misunderstanding, anti-icing fluid is not only winter, in automobile maintenance project normally, often travels 1 year, need to changing engine fluid, special car anti-icing fluid replacement frequency wants height. Except antifreeze, anti-icing fluid also should have anticorrosion and rust removing function. Electromotor and cooling system thereof are that metal manufactures, and have copper, have ferrum, have aluminum, have steel to also have scolding tin. These metals at high temperature contact with water, and time length all can be corroded, and can get rusty.

At present, anti-icing fluid is broadly divided into inorganic salts, polysaccharide and alcohols. Wherein, there is corrosion phenomenon in inorganic salts anti-icing fluid, affects the service life of electromotor; Polysaccharide anti-icing fluid exists that freezing point reducing effect is not good, the shortcoming of poor heat stability; And there is flash-point problem low, fire-hazardous in alcohols anti-icing fluid.

Summary of the invention:

The technical problem to be solved is in that to provide a kind of antifreezing effect and the motor vehicle antifreeze fluid having anticorrosion and rust removing function concurrently and preparation method thereof.

The technical problem to be solved adopts following technical scheme to realize:

A kind of motor vehicle antifreeze fluid, is made up of the raw material of following parts by weight:

Emulsifying glycerol 20-25 part, polyvinyl alcohol 12-17 part, terpene resin 10-15 part, spermol 8-12 part, glucoside 6-10 part, polypropylene glycerol aether 6-10 part, paraffin oil 5-8 part, dodecylbenzene sodium sulfonate 4-6 part, sodium laureth sulfate 3-5 part, Sorbitol 3-5 part, stearic acid 2-3 part, magnesium chloride 1-2 part, rare earth 0.1-0.2 part, Polyethylene Glycol 20-25 part, water 120-150 part.

The preparation method of a kind of motor vehicle antifreeze fluid, comprises the steps:

(1) in emulsifying glycerol, add terpene resin and stearic acid, after mix homogeneously under microwave frequency 2450MHz, power 800W microwave treatment 15min, add paraffin oil and magnesium chloride, at 0��5 DEG C, place 12h after being sufficiently mixed, obtain material I;

(2) in water, add polyvinyl alcohol and spermol, first heat to 60-70 DEG C of insulation mixing 10min, be again heated to reflux state insulation 15min, obtain material II;

(3) in material II, glucoside, polypropylene glycerol aether and dodecylbenzene sodium sulfonate are added, at-5��0 DEG C, 8h is placed after being sufficiently mixed, under room temperature, add material I, sodium laureth sulfate, Sorbitol, rare earth and Polyethylene Glycol, be sufficiently mixed uniformly.

The invention has the beneficial effects as follows: the present invention is with emulsifying glycerol for primary raw material, it is aided with polyvinyl alcohol, terpene resin and multiple auxiliary agent and prepares motor vehicle antifreeze fluid, this anti-icing fluid have excellence antifreezing effect, can effectively reduce freezing point, it is ensured that winter electromotor normal operation; And have good anticorrosion and rust removing function concurrently, can effectively extend the service life of electromotor, reduce replacement cost.
