摘要

Disclosed are an eco-friendly road surface coating material for thawing ice and snow and the methods of preparing and using the same. The preparation method includes the following steps: 1) adding 10~50 parts by weight of snow thawing substances into 50~100 parts by weight of water, after dissolving the snow thawing substances completely, adding sodium hydroxide solution to adjust pH to be 8~10, then adding 10~50 parts by weight of support material, and stirring, baking, milling and sieving to obtain a support powder loaded with snow thawing substances; 2) adding 15~40 parts by weight of the support powder loaded with snow thawing substances into 10~30 parts by weight of cation emulsified asphalt, then adding 10~30 parts by weight of aqueous epoxy resin, 10~50 parts by weight of water and curing agent of aqueous epoxy resinto obtain the coating material for thawing ice and snow.
