Abstract

The invention provides a snow-melting agent and a preparation method thereof and a road fog sealing layer containing the snow-melting agent. The snow-melting agent is prepared from emulsified asphalt and encapsulated salt emulsion, wherein the encapsulated salt emulsion is prepared from an organic non-chlorine salt and a macromolecular encapsulating material, and the mass ratio of the emulsified asphalt to the encapsulated salt emulsion is 1:(0.1-5), preferably 1:(0.2-5). The snow-melting agent disclosed by the invention can be sprayed on the surface of a road before snowfall to form a road fog seal layer, so that the adhesive force of ice and snow on the road surface is weakened, water on the surface of the road is crystallized into a loose and fragile state at a low temperature, is extremely easily crushed by passing vehicles and is further melted into a liquid state, and an ice layer adhered to the road surface is not generated. The snow-melting agent disclosed by the invention is high in snow-melting and deicing efficiency, greatly improve the ice and snow resistance of a road, avoids road closure, and reduces traffic accidents.

Description

technical field [0001] The present invention relates to a snow melting agent and its preparation method and a road fog sealing layer containing the snow melting agent, in particular to a microencapsulated snow melting agent and its preparation method and a road fog sealing layer containing the snow melting agent, belonging to the field of road construction . Background technique [0002] The impact of ice and snow weather on the highway system has become increasingly prominent. On the one hand, it reduces driving safety and leads to traffic accidents; on the other hand, it reduces the traffic capacity of the road network, causing traffic interruption and system paralysis in severe cases. In particular, the long-lasting and large-scale ice and snow extreme climate may also cause serious social problems and cause huge economic losses. At present, the removal method and the melting method are most commonly used for road ice and snow in winter at home and abroad. The removal ...
