Freeze the low-temperature bending failure strain of liquid asphalt, and meet《Standard specification for construction and acceptance of highway asphalt pavement》JTGF40-2004
Requirement, the anti-freezing property of asphalt is greatly increased after sprinkling anti frozen liquid.
In actual use, can according to actual needs after 10~100 times of dilute with water, then using sprinkling wagon to asphalt road
Face is sprayed, and to prevent bituminous paving from freezing, its specific operation principle is as follows：
When temperature is less than 0 DEG C, anti frozen liquid of the present invention is sprayed toward bituminous paving, it is few due to be with the addition of in anti frozen liquid of the present invention
The acrylate copolymer of amount, therefore with certain viscosity, poor fluidity, along with a large amount of holes that pitch has in itself, because
This its will not collect on asphalt roads, cross flow, but slowly penetrated into hole in the certain depth on bituminous paving top layer,
A protective layer is formed, when snowing, ice and snow on road surfaces is in contact with protective layer, the inorganic and organic freezing point reduction in protective layer
Agent is contacted with ice and snow, and it is melted into rapidly snow-broth, and the freezing point depressant penetrated into bituminous paving deep layer also can be at any time
The change of concentration difference is gradually moved up, and is discharged into snow-broth, and with snow-broth, freezing point reduction machine concentration increases, and the liquid phase of water is steamed
Air pressure declines, and the solid-state vapour pressure of ice is constant, more and more in order to reach the state of mixture of ice and water solid-liquid vapour pressure balance
Ice just start melt, such that it is able to prevent and delay winter bituminous paving freeze phenomenon.When snowfall is excessive, sprinkling it is freeze proof
When liquid is not enough to all melt ice and snow on road surfaces, directly can carry out deicing toward sprinkling anti frozen liquid on ice and snow.
The present invention is in the anti frozen liquid of bituminous paving, addition inorganic salts sodium chloride to have as Snow Agent to asphalt roads
Standby certain freeze proof anti-icing protective capability, and raw material be easy to get, it is cheap, but its corrosion to large-scale public infrastructure
Destruction with ecological environment is very serious, so the consumption of sodium chloride is less in the present invention.Meanwhile, it is added with corrosion inhibiter phosphoric acid hydrogen two
Nutrient phosphorus and potassium needed for potassium slows down this destruction to reduce, and dipotassium hydrogen phosphate contains plant growth, anti-
Freeze liquid washed away by rainwater or snow melt, inlet channel on both sides of the road when, ecological environment will not be damaged, and can be afforested as roadside
The fertilizer of plant.Potassium formate is a kind of organic Snow Agent, does not have corrosion-damaged substantially to asphalt roads, but due to its freezing point compared with
Height, is difficult to be used in the relatively low area of temperature, significantly limit its range of application and region；And present invention addition ethylene glycol conduct
Antifreezing agent, on the one hand can act synergistically with sodium chloride and sodium formate, play more preferable cryoprotective effects, and on the other hand it is used as one
The liquid for organically possessing certain viscosity is planted, is mixed with sodium chloride and sodium formate in system, play a part of sustained release.
In order to strengthen this slow release, the present invention also added a small amount of acrylate copolymer to increase viscosity, delay each active ingredient
On The Drug Release.But the aqueous solution of acrylate copolymer is acidity, therefore in order that the final product pH value prepared remains neutral,
Potassium hydroxide is with the addition of in formula to neutralize acrylate copolymer, but the aqueous solution of acrylate copolymer and potassium hydroxide react
The viscosity of system can increase suddenly afterwards, and product viscosity is excessive, and the friction of asphalt roads can be then reduced when being sprayed at bituminous paving
Power, is easily caused accident generation, so with the addition of EDETATE SODIUM in the present invention to reduce viscosity, its viscosity is maintained at a conjunction
In suitable scope.Ac-Di-Sol has certain water-retaining property and slow release, and active ingredient is delayed in can making product
