Description
Technical field
The present invention relates to Snow Agent technical field, particularly relate to a kind of low-cost environmental-protecting composite snow-melting deicer and making thereof
Method.
Background technology
Winter, ice and snow was the factor group having a strong impact on transportation, and icy road accumulated snow is to affect China mostly
The important safety hidden danger that district's traffic in winter runs, makes traffic capacity decline to a great extent, and easily causes vehicle accident, the soonest
Speed ice-melt snow removing becomes China's traffic in winter undoubtedly and runs the unobstructed key issue needing solution badly, and Snow Agent produces therewith.
Snow Agent as its name suggests, is used to reduce the salt of ice and snow freezing point, and its effect is deicing or snow melting, because of its use simply,
Deicing snow melt is effective waits many merits, mainly as the snow removing of the facilities such as urban road, highway, airport, harbour, bridge
Changing ice, some Snow Agent also act as agent for quick melting and the antifreezing admixture etc. of architectural engineering winter construction ice dissolution.Snow Agent
Road, concrete component, bridge facility can not there be is infringement after using, flowers, plants and trees, crops, animal and right can not be destroyed
People has infringement.At present, the villaumite type agent for melting ice and removing snow with sodium chloride as representative is widely used in different kinds of roads ice-melt snow removing,
And the environmental problem using chloride Snow Agent to cause for a long time highlights the most day by day, the chloride ion corrosiveness to road and bridge is right
The impact of plant growing, causes the extensive concern of people to problems such as the pollutions of water body.The eighties in 20th century, U.S. DOT is public
Department develops environment-friendly type calcium acetate magnesium salt (CMA) Snow Agent first, its low corrosivity and to the less harmful of vegetation by the world
Recognized by.But, due to the price problem of its raw material acetic acid so that CMA Snow Agent is difficult to Rapid Popularization, China is only at aircraft
The minority places such as field use.Therefore, use cheap acetic acid and calcium, magnesium predecessor to research and develop the calcium acetate of low cost
Magnesium salt Snow Agent, becomes the important subject eradicating the harm of chloride salt Snow Agent.
" preparation of a kind of low-cost environment-friendly Snow Agent and performance study " selected works are selected by biomass waste material (straw, wood
Bits etc.) the russet waste liquid of generation during carbonization fuel gas, biodegradable and low cost wood vinegar is raw material,
Its acetic acid content of wood vinegar raw material used by this method is up to 6%-12%, and possibly together with a small amount of propanoic acid (about 0.6%), formic acid is (about
0.3%), phenol, tar etc., have studied the process of the CMA class Snow Agent of preparation low cost, products obtained therefrom is low-carbon (LC) mixing
Calcium magnesium carboxylate, by a series of performance tesies of Snow Agent are shown, its snow melt temperature low (minimum up to-34 DEG C), snow melt
Efficiency is high (up to 208.3 cm3Snow/g Snow Agent), to the no corrosion such as metal, flowers and plants and infringement, the performance of each side is equal
It is better than the villaumite Snow Agent such as sodium chloride.
Current existing Snow Agent has powder and two kinds of forms of liquid, and liquid is sprayed on ice and snow face with atomizing type melts
Changing ice and snow, be uniformly dispersed but easily infiltrate into road surface, can bring certain corrosion-damaged, being directly spread on snow face of powder is melted
Snow, but intensity is low and density little Yi is blown to four winds, and causes disperseing uneven, and snow melt effect declines, it is necessary to is improved and makes
The snow melt deicer that intensity is high, had not only been difficult to be blown to four winds by car crushing difficulty but also have preferably heat absorption, absorption property, had accelerated snow melt
Deicing speed also has low corrosion, pollutes the spies such as little, little to plant injury, combination property is high, function diversification, storage convenience
Property.
Summary of the invention
The object of the invention is contemplated to make up the defect of prior art, it is provided that a kind of low-cost environmental-protecting composite snow-melting deicer
And preparation method thereof.
The present invention is achieved by the following technical solutions:
A kind of low-cost environmental-protecting composite snow-melting deicer, is prepared by the raw materials in: wood vinegar 60-62, forsterite
Sand 13-15, Glycine max (L.) Merr. 10-12, wheat straw 8-10, rape straw 15-17, emulsion acrylic resin 16-18, pure-acrylic emulsion 9-11, make
Paper black liquor 25-27, polypropylene fibre 7-9, natrium carbonicum calcinatum 2-3.
The manufacture method of described a kind of low-cost environmental-protecting composite snow-melting deicer, comprises the following steps:
(1) wheat straw, rape straw are dried to moisture content < 25%, attrition grinding crosses 200 mesh dusting covers, add emulsion acrylic resin,
Glycine max (L.) Merr. stirring and evenly mixing stand 12-14 hour, pelletize, put in 80-100 DEG C of baking oven be dried 10-12 hour, under nitrogen protection
Sinter 20-30 minute in 700-1000 DEG C, obtain anti-skidding auxiliary agent；
(2) by forsterite sand, natrium carbonicum calcinatum stirring and evenly mixing, put in black liquid and impregnate 10-12 hour, ultrasonic grinding
