This invention belongs to chemical category, it is complex salt field. It is consisted by three, four, five kind of water, calcium nitrate, calcium chloride, magnesium chloride, aluminum chlorate or polyaluminium chloride, calciuim hypochlorite, sodium hypochlorite, sodium peroxide seven chemical materials, and at least two kinds of dium metasilicate, sodium molybdate, sodium tripolyhosphate, benzapyrene three nitrogen azole, sodium benzoate and water quality stabilizer-PTX-CS used as corrosion inhibitor. 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.
