Description
Technical field
The present invention relates to deicing salt technical fields, and in particular to a kind of water base deicing salt and preparation method thereof.
Background technology
The effect of deicing salt is to melt ice and snow.It is divided into solid and liquid by states of matter；It is divided into inorganic matter and inorganic matter by composition
With the mixing of organic matter.Common deicing salt includes using potassium acetate organic deicing salt as main component and is main using villaumite
The inorganic deicing salt of ingredient.
In contrast, organic deicing salt is smaller for damages such as road, concrete component, bridge facility and flowers, plants and trees,
But its price is too high；And inorganic deicing salt is since its is cheap, even if it is big to the damage of facility compared with organic deicing salt, but due to
Its relative usage is less.Under comprehensive consideration, inorganic deicing salt is still widely used in merging into nature, and most is
Sodium chloride（That is Nacl）.
For ease of using, Nacl all directly sheds use using solid, in order to avoid being damaged to facility, usually makes
Dosage is less, and due to shedding unevenness, also height is different for the saline solution concentration of formation, in turn results in the ice height of mixture not
Together, average freezing point can only achieve at -5 DEG C, and solid industrial salt can form slush after being contacted with ice and snow, it is impossible to voluntarily flow, need
Artificial or equipment is rooted out again, time-consuming and laborious.
Invention content
The object of the present invention is to provide a kind of low, small, easy to use, at low cost to the facility damage water base snow melts of freezing point
Agent.
The present invention adopts the following technical scheme that：
It is prepared by a kind of water base deicing salt, the raw material including following parts by weight：8 ~ 12 parts of sodium chloride, 1 ~ 5 part of alum, mass fraction
For 30% 0.9 ~ 1.5 part of hydrogen peroxide and supply 100 parts of water.
Preferably, prepared by the raw material including following parts by weight：10 parts of sodium chloride, 3 parts of alum, mass fraction are 30%
1.2 parts of hydrogen peroxide and supply 85.8 parts of water.
Further, it is prepared via a method which：
（1）It takes sodium chloride and alum soluble in water, is stirred and heated to 45 ~ 60 DEG C, continues 5 ~ 10min；
（2）To step（1）Solution in add in hydrogen peroxide, water is added to supply, and adjust system pH as 5 ~ 6.5；
（3）Keep temperature be 45 ~ 55 DEG C, persistently stir 10 ~ 20min to get.
Further, the step（1）Heating temperature be 50 DEG C.
Further, the step（2）PH be 5.0.
Further, the step（2）It is middle to use H2SO4The pH of regulation system.
The beneficial effects of the present invention are：By the chemical combination and redox reaction of several inorganic salts, generate a kind of new
The special low temperature resistant saline solution of type, i.e., freezing point is at -35 DEG C ~ -38 DEG C.Solid snow can be melted in extremely frigid zones, snow-broth does not freeze
And directly flow away, it is 6.5 ~ 7.5 that the snowmelt after snow melt, which can reach pH, meets the discharge standard of national environmental protection.
Specific embodiment
In order to deepen the understanding of the present invention, the present invention is described in detail with reference to embodiment, the embodiment
It is exemplary, is only used for explaining the present invention, protection domain is not formed and is limited.

（2）To step（1）Solution in add in hydrogen peroxide, water is added to supply, and adjust system pH as 5；
（3）Keep temperature be 45 DEG C, persistently stir 10min to get.
In use, according to water base deicing salt: water 1: 10, according to 0.5kg/m2, it is applied to ice and snow road.
Embodiment 2
（1）It takes sodium chloride and alum soluble in water, is stirred and heated to 60 DEG C, continue 10min；
（2）To step（1）Solution in add in hydrogen peroxide, water is added to supply, and adjust system pH as 6.5；
（3）Keep temperature be 55 DEG C, persistently stir 20min to get.
In use, according to water base deicing salt: water 1: 10, according to 0.8kg/m2, it is applied to ice and snow road.
Embodiment 3
（1）It takes sodium chloride and alum soluble in water, is stirred and heated to 50 DEG C, continue 8min；
（2）To step（1）Solution in add in hydrogen peroxide, water is added to supply, and adjust system pH as 5.0；
（3）Keep temperature be 50 DEG C, persistently stir 15min to get.
In use, according to water base deicing salt: water 1: 10, according to 1kg/m2, it is applied to ice and snow road.
Effect example 1
Ten times of dilutions of water base deicing salt, embodiment 1 ~ 3 obtained by by embodiment 1 ~ 3, using mass fraction as 10% and 1%
Sodium chloride solution measures freezing point, the results are shown in Table 1 as control.
The freezing point of the different deicing salts of table 1
。
By table 1 it is found that the freezing point of deicing salt can reach -35 ~ -38 DEG C, ten times of dilutions that when normal use uses
Liquid can also reach -15 ~ -18 DEG C, and performance is far superior to the sodium chloride with concentration, can adapt to the snow melt needs of extremely frigid zones, melts
Snow-broth is not easy to freeze and can directly flow away, and avoids common deicing salt and forms slush, without artificial after-treatment.
