Description
Technical Field
The invention relates to an environment-friendly snow-melting agent and a preparation method thereof, which can be widely applied to the field of melting of ice and snow on road traffic.
Background
The snow melting agent is an agent for assisting melting of ice and snow, and is a chemical. At present, the snow-melting agent has more types and is divided into solid and liquid according to the state of matter; the components are inorganic substances and mixture of the inorganic substances and the organic substances. The existing snow-melting agent has easily available raw materials and low price, and the components of the snow-melting agent are mainly chloride and acetate which are classified. The snow melting agent can melt snow on roads by reducing the melting temperature of the snow and ice, and can be used for removing snow and melting ice on urban roads, expressways, airports, ports, bridges and other facilities. Although the snow-melting agent is convenient for dredging roads and has obvious effect on scattering places, the snow-melting agent has little harm. Research shows that most of snow-melting agents used at present can corrode road surfaces and automobile rubber tires, and also have damage to concrete members and bridge facilities, can damage flowers, plants, trees, crops and animals, and also damage human health. Therefore, in the north of China, in the normal winter, the ice and snow on the road surface are removed by adopting a mode of taking sandy soil and a snow scraper as main materials and taking a snow melting agent as an auxiliary material so far, and the smooth traffic is ensured.
From the viewpoint of snow melting principle, most of the snow melting agents used up to now are based on the point of "freezing point depression". There are also small amounts that involve the release of heat of dissolution of anhydrous compounds such as anhydrous calcium chloride when dissolved in water. Snow-melting agents based on other snow-melting principles have not been found so far. This also reflects that there is much room to explore in the basic research of snow melting principle.

The invention relates to an environment-friendly snow-melting agent, wherein the slag powder is 200-mesh slag powder.
The invention relates to a method for preparing an environment-friendly snow melt agent, which comprises the following steps of proportioning the components of the environment-friendly snow melt agent in parts by mass, and firstly, impregnating natural zeolite slag with waste heat-conducting oil in the parts by mass for 3-6 hours; then adding the petroleum coke powder and the slag powder in the mass part ratio, and stirring for 2-8 hours; and finally, adding the sodium silicate solution according to the mass part ratio, spraying and granulating, and drying at the temperature of 20-80 ℃ to obtain the environment-friendly snow-melting agent finished product.
The invention relates to an environment-friendly snow-melting agent and a preparation method thereof, and the working mechanism is as follows: the blackness coefficient of the environment-friendly snow-melting agent material is utilized to improve the absorption capacity of the ice and snow to the heat radiation of the sun or other objects, so as to melt the ice and snow. The blackness coefficient refers to the absorption capacity of an object to radiation, and if 100% of radiation is absorbed, the blackness coefficient is 1, and if not, the blackness coefficient is 0. The heat radiation of the sun or other objects belongs to radiation heat exchange, the principle is that the radiation heat exchange is carried out between two objects which have different temperatures and are not in contact with each other, and the heat exchange process carried out through electromagnetic waves is one of the important modes of heat transfer. Every object in nature can continuously emit radiant heat to the space, and simultaneously can continuously absorb the radiant heat emitted by other objects. The radiation heat exchange between the solid surfaces depends on the radiation angle coefficient F and the blackness epsilon value, the blackness epsilon value of the white ice and snow approaches to 0, the reflectivity of the white ice and snow to solar heat radiation is up to 90%, and the white ice and snow can only absorb about 10% of the solar heat radiation energy. And dark or black materials, such as dark or black, have a blackness epsilon close to 1 and a reflectivity of 10-0%, and compared with white ice and snow, the absorption phase of the radiation heat exchange energy of the dark or black materials is about 9 times worse. The blackness coefficient of the environment-friendly snow-melting agent material is utilized to improve the snow melting capability.
