Abstract
The invention relates to an environment-friendly snow melting agent and a preparation method of the snow melting agent, and belongs to the field of the snow melting agents. The snow melting agent is prepared from acetates and chlorine salts with low corrosivity as the main raw materials by mixing acetates including potassium acetate, magnesium acetate and calcium acetate with calcium chloride and magnesium chloride in a certain proportion, as well as a small quantity of corrosion inhibitor. The common fault that a common inorganic snow melting agent is high in corrosivity is effectively overcome, the cost is reduced, and therefore the snow melting agent is suitable for promotion and application.
Description
Technical field
The present invention relates to a kind of environment-friendly snowmelt agent and preparation method thereof, particularly relate to preparation prescription and the preparation technology of this environment-friendly snowmelt agent.
Background technology
Winter, ice and snow brought serious hidden danger to traffic safety all the time, because the traffic accident that ice and snow road causes has caused enormous economic loss and loss of life and personal injury.The snow removing mode mainly is divided into snow removal with machine and chemistry snow removing dual mode at present.Wherein, snow removal with machine maneuverability, speed are fast, applied widely, but have deficiencies such as Ex-all rate variance, fragile road surface; The snow-removing method of chemistry Snow Agent can remedy the deficiency of snow removal with machine, is a kind of effective deicing or snow melting means, and its use is irreplaceable.The type of the Snow Agent of Snow Agent and amount of application are generally comprehensively determined in conjunction with climatic characteristic, the snowfall of this area according to different areas.Current Snow Agent comprises chloride salt and non-villaumite two big classifications, the chloride salt Snow Agent belongs to inorganic Snow Agent, pitch and cement concrete pavement, bridge, soil, roadside trees, greening and physical environment are caused to a certain degree destruction, field irrigation water source water quality and municipal Infrastructure are had a strong impact on according to causing, and this influence is paid attention to by society day by day.Non-chloride salt Snow Agent comprises organic Snow Agent such as acetic acid salt and urea, and the principal feature of such Snow Agent is expensive, and it is many that snow melt relies on natural cause restrictions such as temperature, daylight, the snow melt long reaction time.Current environment-friendly snowmelt agent of generally acknowledging in the world only limits to the acetate series products, this product slate raw material type is less, production technique is simple, the characteristics of environmental protection meet the Economic development policy of China, but because the restriction of economic factorss such as cost, some developed countries also can only use on a small quantity.China is developing country, the more impossible a large amount of uses in a short time of non-villaumite type Snow Agent.But environment protection comes into one's own day by day, and particularly high-grade highway, large-scale bridge floor, particularly steel bridge face etc. more need environment-friendly snowmelt agent.
Summary of the invention
Goal of the invention:
In order to address the above problem, the present invention proposes a kind of environment-friendly snowmelt agent and preparation method thereof, effectively improve the high common fault of common mineral-type Snow Agent corrodibility, and reduced the cost of the organic Snow Agent of CMA class in the world.
Technical scheme:

Advantage and effect:
Compare with sodium-chlor, this environment-friendly snowmelt agent of the present invention has better water solubility, and the ice eutectic point is lower, biodegradable and have a very strong snow melt ability, can make accumulated snow loosening, easier rooting out, and to very low along the aspects such as toxicity of influence, soil and the contaminated water source of road plant, corrosion of metal, chemical, meet national environmental standard.
The present invention does not need additionally to increase rare material in raw-material use, all major ingredient constitutes by common salt, when having reduced production cost, has also simplified production technique.
The Snow Agent deicing or snow melting performance of producing by prescription of the present invention and manufacture craft is good, freezing point is low, little, extremely low to farmland and afforestation vegetation destructiveness to the corrodibility of materials such as the metal of municipal Infrastructure and concrete, and the simple advantage of production technique, be fit to industrialization production.
Description of drawings:
Fig. 1 is process flow sheet of the present invention.
Embodiment:
Below in conjunction with accompanying drawing the present invention is added and to be described further:
Principle of work of the present invention is as follows:
The principle of Snow Agent deicing or snow melting mainly is to utilize the freezing temperature of the material reduction moisture content of snow melt effect, melts new snow in the snowfall process, prevents that accumulated snow from freezing.Because the freezing point of snow-melting agent is lower, directly is sprinkled upon on the ice and snow on road surface, freezing ice sheet accumulated snow is disappeared be frozen into water.Compare with sodium-chlor, this environment-friendly snowmelt agent has better water solubility, and the ice eutectic point is lower, biodegradable and have a very strong snow melt ability, can make accumulated snow loosening, easier rooting out, and to very low along the aspects such as toxicity of influence, soil and the contaminated water source of road plant, corrosion of metal, chemical, meet national environmental standard.
This product does not need additionally to increase rare material in raw-material use, all major ingredient constitutes by common salt, when having reduced production cost, has also simplified production technique.
Environment-friendly snowmelt agent is main raw material with acetate and the lower villaumite of corrodibility, mainly comprises acetic acid first, magnesium acetate and calcium acetate, allocates a certain proportion of calcium chloride and magnesium chloride and a spot of inhibiter into.During production various starting material are all fully pulverized, formed powder, fully mix in proportion, through granulation process, make particulate state or sheet to also.
The Snow Agent deicing or snow melting performance of producing by prescription of the present invention and manufacture craft is good, freezing point is low, little, extremely low to farmland and afforestation vegetation destructiveness to the corrodibility of materials such as the metal of municipal Infrastructure and concrete, and the simple advantage of production technique, be fit to industrialization production.
