Description
Technical field
The present invention relates to chemical field, specifically a kind of preparation method of deicing fluid.
Background technology
The full name of deicing fluid is anti-freeze cooling liquid, mean the cooling fluid of antifreeze function, unfrozen cooling fluid when deicing fluid can prevent from cold season from stopping and spalling scatterer and freezing engine cylinder block, also can prevent engine long time service (especially summer) from causing engine water tank to boil; Engine and cooling system thereof are metal manufactures simultaneously, cupric, iron content, also has scolding tin etc. containing aluminium, steely, these metals at high temperature contact with water, time has been grown and all can have been corroded, can get rusty, all deicing fluid especially automotive antifreezing liquid must have antifreeze, anti-ly to boil, protection against corrosion, the several functions such as scale-deposit-preventing; Deicing fluid also can be used in other recycle systems, prevents the recycle system at low temperatures because freeze cause the spalling of recycle system pipeline, thus affects the normal operation of the recycle system.
Current deicing fluid mainly contains water/ethylene glycol type, water/propylene glycol, water/glycerol type, ethylene glycol, propylene glycol are petroleum refining product, be all Nonrenewable energy resources, along with the aggravation of energy dilemma, ethylene glycol, propylene glycol supply can decline, need to find new environmental protection, reproducible starting material carry out alternative ethylene glycol, propylene glycol for the production of deicing fluid, thus reduce petroleum-type product according to patience; Therefore, glycerol is a kind of extraordinary substitute products, and glycerine is the by product producing soap, lipid acid and biofuel, recyclable regenerative, but glycerol heat transfer coefficient is low, can affect engine cool efficiency in engine operation process.
Summary of the invention
The object of the invention is to the deicing fluid preparation method that a kind of environmental protection is more provided to overcome the deficiencies in the prior art.
To achieve these goals, the invention discloses a kind of preparation method of anti-freezing liquid, it is characterized in that: be composed of the following components in mass ratio:
Antifreeze medium 10.0-55.0%
Inhibiter 0.2-5.0%
Press down bubble defoamer 0.01-0.05%
Pigment 0.01-0.5%
Deionized water surplus;
Preparation method is as follows: first by antifreeze medium and deionized water uniform stirring, then add inhibiter, at 5-35 DEG C, stir 30-60 minute, finally adds defoamer and pigment stirring 30-60 minute, obtains deicing fluid.
Compared with the prior art, the present invention selects synthetic glycerine to coordinate α, α, α '-trimethylammonium trimethylene ethylene glycol, N methyldiethanol amine, as antifreeze medium, are environmental protection renewable resourcess, the dependence to the non-renewable petroleum-type product of tradition can be solved, simultaneously by adding α, α, α '-trimethylammonium trimethylene ethylene glycol, N methyldiethanol amine, can viscosity be reduced, solve shortcoming low with glycerine heat transfer coefficient separately; The inhibiter adopted can improve the base number of system, makes deicing fluid base number in long-play process remain in a stable scope; 2,4,6-tri-(caproyl aminomethyl sulfo)-s-triazine keeps the long-time protection to cast iron, steel part; Nucite phosphoric acid ester has inhibition and deactivation function to many metals, has complexing function simultaneously, reduces deicing fluid fouling in operational process; Sodium lignosulfonate is as pigment, natural pigment, biodegradable, be a kind of environmental protection tensio-active agent of recyclable regenerative, there is dispersion and wetting ability, there is heavy metal simultaneously, especially iron, copper, stannous ion have good sequestering power, are effective sequestrants, and red bean criticizes pigment, acorn cup palm fibre uses together in cooperation, the deicing fluid recalled is bright-colored, not fugitive color; A kind of glycerin base deicing fluid of allotment has the features such as, freezing point low, boiling point high, good antiscale property, long service life effective to many corrosion inhibition for metal, and can extend the work-ing life of cooling system, environmental protection is renewable.
Below by way of specific embodiment, explanation is further explained to technical solution of the present invention.
