Anti-rust snow melting anti-freezing agent

Abstract

The anti-rust snow melting antifreezing agent has added antirust agent in the amount of 1-5 wt%. The antirust agent is citrate, including sodium citrate, magnesium citrate, calcium citrate, etc. and preferably sodium citrate. The anti-rust snow melting antifreezing agent can prevent metal part form rusting, and has no environmental pollution and toxin to animal and plant. It may be used for melting snow, defreezing and preventing freezing in road, airport, park, yard. The present invention is suitable for mechanical application and manual throwing.

Description

technical field [0001] The invention relates to a snow-melting antifreeze agent, in particular to a novel anti-rust snow-melting antifreeze agent capable of suppressing metal rust. Background technique [0002] In areas with cold winters, traffic is difficult due to snowfall, so countries generally adopt measures of throwing snow-melting antifreeze to solve traffic problems caused by snow and ice in winter. Among many kinds of snow-melting antifreeze agents, inorganic salts are widely used because of their fast melting and thawing, economical and applicable. However, inorganic salts are mostly mixtures or complexes of two of sodium chloride, magnesium chloride, and calcium chloride. These materials have a corrosive effect on metal objects such as road signs and automobile chassis. As a countermeasure to solve metal corrosion, there are some anti-rust snow-melting antifreeze agents such as adding sodium metasilicate or phosphate. Although these products can inhibit the gener...
