This invention belongs to chemical category, it is complex salt field. It is consisted by water, calcium nitrate, calcium chloride, magnesium chloride, sodium chloride, sodium hypochlorite, aluminum chlorate, sodium peroxide and other chemical materials, and odium metasilicate, sodium molybdate, sodium nitrate, sodium tripolyhosphate, benzapyrene three nitrogen azole, sodium benzoate, water quality stabilizer-PTX-CS used as corrosion inhibitor. They are compounded by their attribution; there are solid and liquid states. Its sleet melting and snow removing velocity is quickly, environmental capability is good, and it can efficiently reduce the corruption to metal and cement concrete. Plant growth can be boost, and deodorization, bactericidin, purification water quality, pavement cleaning and other function can be realized to water after cleaning of ice and snow. It can be used widely above -400C, and for protecting city communication through, reducing traffic accident, and ensuring human body and auto safety, it has good effect. Is it fit for city and country road, freeway, airport, plaza, court and bridge.
