Abstract

The invention provides a salt-storage slow-release snow-melting and deicing agent and a preparation method thereof, comprising the following steps: firstly preparing a saturated solution of anti-coagulation glacial chloride salt and a suspension of diatomite modified by nano-silica, and then adding the anti-freeze The saturated solution of glacial chloride salt is added dropwise to the diatomite suspension modified by nano-silica, stirred, vacuum filtered, dried, and pulverized to obtain a slow-release inorganic salt; the polymer monomer solution is then prepared, and finally the slow-release Release inorganic salt, isopropanol or propylene glycol methyl ether solution into the flask, put the flask in an oil bath and stir evenly, then add the mixed solution of polymer monomer solution, KH570 and gAIBN to it, continue stirring, and lower the temperature , and then add triethylamine into the flask, stir, and then add water to obtain the salt-storage slow-release snow-melting and deicing agent. The snow-melting substance in the salt-storage slow-release snow-melting and deicing agent prepared by the invention is not limited by temperature-controlling molecules, and the snow-melting substance releases for a long time and has a high melting ice amount.

Description

technical field [0001] The invention belongs to the technical field of road materials, in particular to a salt-storage slow-release snow-melting and deicing agent and a preparation method thereof. Background technique [0002] my country's road network is huge, most of which are located in snow-prone areas. The snow and ice on the road surface in winter greatly reduces the adhesion coefficient of the road surface, which seriously affects the smooth flow of the road and causes traffic safety accidents. The traditional methods of snow melting and deicing include manual mechanical removal method and spraying deicing agent method. However, the artificial mechanical removal method is expensive to remove snow and ice, and the deicing rate is low; the method of spreading deicing agent will cause serious pollution to the environment and corrode the road. . Therefore, the adoption of active, long-term, safe and environmentally friendly snow and ice removal technology will become an...
