S2: it obtains that montmorillonite and carbon nanotube are added in calcium of organic acid to step S1, specific surface area of carbon nanotube is >=233m2/
G, internal diameter 3-5nm, outer diameter 8-15nm, after stirring 12min at room temperature with the revolving speed of 250r/min, are in frequency by 50 μm of length
40kHz, power filter, dry, grinding obtains modified calcium of organic acid to shake 1.5h in the ultrasonic wave of 500W.
Performance test
Ice-melt rate test
500 milliliters of distilled water are injected in ice pan, are placed in refrigerator-freezer, glaciation in 12 hours is freezed under the conditions of -25 DEG C.By ice
Cabinet lid is opened, and temperature is adjusted and arrives -15 DEG C, and each ice pan is displayed.10 grams of ice melting agents are uniformly sprayed onto ice pan in one minute
On face.The water melted was collected at 5,10,20,30 minutes respectively, and is weighed, test result is referring to table 3.

The test of other performances, referring to GB/T 23851-2017, test result is referring to table 4.
4 embodiment 1-8 of table and comparative example 1-4 ice melting agent the performance test results
In conjunction with table 3 and table 4,2-8 ice-melt rate of the embodiment of the present invention is tested, under the conditions of -15 DEG C, is spread when ice melting agent
When generating ice-melt effect in ice face, the ice crack sound of whip can be heard, formed very much " pittings ", melted around ice melting agent
The position of ice agent ultimately forms the ice face in gully in length and breadth, has excellent ice-melt effect at low ambient temperatures, and ice-melt rate is fast.Ice
Point is at -40 DEG C hereinafter, the aggrieved very little of corrosion and vegetable seeds to carbon steel, excellent combination property.Comparative example 1 omits acetic acid
Potassium, the ice-melt rate decline of ice melting agent is obvious, freezing point significantly rises, and comparative example 2 lacks sodium acrylate, the corrosion and plant to steel
The injury of species is maximum；Calcium of organic acid is not modified by comparative example 3, and the ice-melt rate of ice melting agent is decreased obviously, in freezing point
It rises obvious；Comparative example 4 is not modified montmorillonite, and short time Internal melt effect is poor, the comprehensive performance of ice melting agent under
Drop.Illustrate that inventive formulation and technique suitability are good, be between each raw material it is complementary, lack any raw material, material
Performance will be decreased obviously.
The above is a preferred embodiment of the present invention, it is noted that for those skilled in the art
For, without departing from the principles of the present invention, it can also make several improvements and retouch, these improvements and modifications
It should be regarded as protection scope of the present invention.
