Description

Environment-friendly snow-melting and ice-melting composition and preparation method thereof Technical Field The invention relates to the technical field of snow-melting agents, in particular to an environment-friendly snow-melting and ice-melting composition and a preparation method thereof. Background At present, snow-melting agents are mainly classified into chloride-type and non-chloride-type. The chloride ion in the chloride snow-melting agent has strong permeability and corrosiveness, and can seriously damage materials such as metal, concrete and the like. The non-chlorine salt type snow-melting agent takes potassium acetate, sodium acetate, calcium magnesium acetate and the like as main components, has the characteristics of environmental protection and no corrosion, but has high price and relatively poor snow-melting and ice-melting capabilities. In the related art, the biomass environment-friendly non-chlorine deicing and snow-melting agent is disclosed, and comprises the following raw materials, by mole, 10-30 parts of tap water, 15-35 parts of glucose degradation products, 6-20 parts of starch degradation products, 8-18 parts of sucrose, 7-18 parts of citric acid monoglyceride and 2-5 parts of corrosion inhibitors. The main components of the snow-melting agent are saccharide derivatives and organic acid salts, can lower the freezing point, do not contain chloride ion components, have weak corrosion effect, have little influence on the germination rate of seeds by raw materials, and belong to environment-friendly products. However, the speed of melting snow and ice of the organic acid salt is far lower than that of the chloride product, and especially in winter in northern alpine regions with the temperature below minus 30 ℃, the speed of melting snow and ice is slower, and the ice and snow can not be removed in time.
