Description
Technical field
The present invention relates to roads to press down ice snow melt technical field, and in particular to a kind of ice melting agent and preparation method thereof.
Background technology
Icy road was readily occurred in November to a period of time of next year April (i.e. winter and early spring).Northern China
, usually there is icy road phenomenon in area, especially the Northeast and Inner Mongol northern territory.And southern region of China, snowfall
Generally " snow slush " tends to belong to 0~4 DEG C of mixed state water, and landing becomes ice water starchiness, as soon as decline to nighttime temperature,
Large stretch of ice cube can be frozen into, as long as local winter minimum temperature is less than 0 DEG C, it is possible to icy road phenomenon occur, as long as warm
Degree, which is not gone back up to, to be enough ice sheet is made to thaw, and will be just as solid as rocks always.In general, it is severe winter, a wide range of strong cold when occurring
When air activity causes the weather (being known as cold wave in meteorology) of mercury dropped, if with sleet, it is easiest to that icy road occurs
Phenomenon.
When there is icy road, since wheel and pavement friction effect weaken significantly, easily skid, stop and do not live vehicle, cause
Traffic accident.Pedestrian also easily slips, and causes tumble injury.At the beginning of 2008, persistently there is sleet, frost in more than ten of province of south China
Weather are waited, causing a plurality of highway, Civil Aviation Airport is largely accumulated because of runway, airplane parking area because of road snow mantle icing first rear enclosed
Snow freezes and closes, and personnel's goods and materials can not transport, and traffic is caused and is seriously affected.
Therefore, a kind of ice melting agent for being capable of quick ice-melt is developed, becomes the technical issues of urgently to be resolved hurrily.
The content of the invention
In view of the deficiencies of the prior art, it is fast with ice-melt speed the object of the present invention is to provide a kind of ice melting agent, it is nontoxic,
It is tasteless, it is easy to produce the characteristics of；It is scientific and reasonable, simple and practicable the present invention also provides its preparation method.
Ice melting agent of the present invention is made of the raw material of following parts by weight：
Preferably, it is made of the raw material of following parts by weight：
Wherein：
The water absorbent gel is one or both of nano-cellulose aerogel or starch gel.
Preferably, the water absorbent gel is the mixture of nano-cellulose aerogel and starch gel, the quality of the two
Than for 2~5：1.
The preparation method of ice melting agent of the present invention, step are as follows：
(1) magnesium acetate with calcium acetate is uniformly mixed, obtains mixture A；
(2) sodium metasilicate and benzotriazole are added to the water, stir, obtain mixture B；
(3) by ethylene glycol, ethyl alcohol and glycerine mixing, mixture C is obtained；
(4) mixture A and mixture B are added in mixture C, mixing obtains mixture D；
(5) it is stirred continuously down, water absorbent gel is added dropwise into mixture D, after dripping off, stands, obtain ice melting agent.
When the standing is that standing 2~3 is small at 30~50 DEG C.The structure of ice melting agent can be stablized, extend its effect
Time, and then enhance its ice melting capability.
In conclusion beneficial effects of the present invention are as follows：
(1) present invention can reduce the solidification of ice and snow using magnesium acetate and calcium acetate through being compounded to form readily soluble salts substances
Point plays the role of eliminating ice and snow.In addition, readily soluble salts substances will not generate corrosiveness to road and bridge, it will not be to water
Body generates pollution, safety and environmental protection.
(2) present invention is compound using ethylene glycol, ethyl alcohol and glycerine, adds hydrogen bond, reduces further solidification point.
(3) present invention is using sodium metasilicate, and since silicate material easily forms colloidality structure, and metasilicate has
Preferable stability and good Corrosion Protection.
(4) present invention is improved the heat conduction velocity of ice melting agent and metal, and can be slowed down rust deposite using benzotriazole
Growing amount weakens the decline of pH value, while it also has good anti-corrosion effect.
(5) present invention is compound using nano-cellulose aerogel and starch gel, and gel is made of the nanofiber grown, fine
A large amount of hydrogen bonds can be formed between dimension, interfibrous winding effect is apparent in solution, on the one hand can enhance the intensity of ice melting agent, extension is melted
The action time of ice agent；On the other hand its ability combined with water can be enhanced, improve ice-melt speed.
(6) preparation method of the present invention, it is scientific and reasonable, simple and practicable.
