Abstract: A novel plant-friendly and environmental-friendly snow-melting agent with low corrosion is developed via the screening of components,the optimization of the ratio of snow-melting agent and the addition of corrosion inhibitors.The ice melting ability,corrosion property and plant impact of various snow-melting agent samples are comprehensively tested.It is indicated that the developed sow-melting agent melts ice several times as much as traditional sodium chloride-based snow-melting agent does within 30 min at -25℃,exhibiting a high efficiency.Compared with traditional sodium chloride snow-melting agent,the corrosion of the aqueous solution of the developed snow-melting agent to steel drops by about 93.29% within 72 h,reflecting a low corrosion property.The novel snow-melting agent has also generated hardly damage to winter mint,a kind of commonly used green plant,in six days.This snow-melting agent exhibits plant-friendly and environmental-friendly properties in comparison to traditional sodium chloride-based snow-melting agent.
