Abstract

The invention relates to an environmental-friendly fulvic acid compound snow-melting agent and belongs to the technical field of materials for roads. The environmental-friendly fulvic acid compound snow-melting agent is prepared by the following steps: by taking lignite as a raw material, crushing the lignite and pre-oxidizing and degrading the lignite with hydrogen peroxide; then combining the lignite with glacial acetic acid; under microwave irradiation, further oxidizing and degrading the lignite to extract fulvic acid; generating more functional groups such as carboxylic acid, alcohol, amine and ester capable of reducing the freezing point; then performing purification and performing a reaction with carbide slag and magnesium oxide and the like to generate fulvic acid/calcium acetate magnesium; and finally, compounding with ammonium chloride to prepare the environmental-friendly fulvic acid compound snow-melting agent. The environmental-friendly fulvic acid compound snow-melting agent prepared by the invention is good in snow-melting effect and small in damage to vegetables, meets the environmental-friendly requirements, is rich in nutritional elements needed by plants to facilitate nutrient adsorption of the vegetables, and has a wide application prospect.

Description

technical field [0001] The invention relates to an environment-friendly fulvic acid composite deicing agent, which belongs to the technical field of road materials. Background technique [0002] Ice and snow accumulation on roads is an important safety hazard affecting traffic operation in winter in most parts of my country. It not only greatly reduces the transportation capacity, but also easily causes traffic accidents. Rapid ice melting and snow removal are undoubtedly the key issues that need to be solved urgently for smooth traffic operation in winter. At present, there are three main methods of deicing and snow melting: manual snow removal, mechanical snow removal, and snow melting agent snow removal. Among them, snow melting agent is widely used because of its simple method, easy operation, and fast snow melting speed. [0003] The development trend of deicing agent is from traditional single chlorine salt deicing agent to multi-component organic deicing agent. At pr...
