Problems solved by technology

[0002] Deicing salt, also known as deicing agent, is a kind of deicing agent. As the name implies, it refers to a chemical that can reduce the melting temperature of ice and snow. Most of the traditional deicing salt is composed of sodium chloride, calcium chloride, The composition of magnesium chloride, potassium chloride, etc. has the advantage of being cheap, which is only equivalent to 1 / 10 of the organic deicing agent, but its corrosion to large-scale public infrastructure is very serious. Therefore, we propose an effective Additives for inhibiting freezing and thawing corrosion damage of melting salt

Abstract

The invention discloses an additive for effectively inhibiting freezing-thawing corrosion damage of melting salt in the field of additive technology, and the additive for effectively inhibiting freezing-thawing corrosion damage of melting salt includes the following material composition: active nano Material 5-40%; Silicate: 5-40%; Silicone material: 5-30%; Fatty acid salt: 1-10%; Preservative: 0.5-5%; Surfactant: 0.5-5%; The balance is water; the production method is simple, by mixing and testing the materials, when a 3.5% salt water freeze-thaw cycle test is carried out, -20°C, 25 freeze-thaw cycles, the test result: the test piece soaked with the additive mixture of the present invention , the average freeze-thaw loss rate was 1.15%; while the loss rate of the blank specimen was as high as 19.5%.

Description

technical field [0001] The invention relates to the technical field of additives, in particular to an additive for effectively inhibiting freezing and thawing corrosion damage of melting salt. Background technique [0002] Deicing salt, also known as deicing agent, is a kind of deicing agent. As the name implies, it refers to a chemical that can reduce the melting temperature of ice and snow. Most of the traditional deicing salt is composed of sodium chloride, calcium chloride, The composition of magnesium chloride, potassium chloride, etc. has the advantage of being cheap, which is only equivalent to 1 / 10 of the organic deicing agent, but its corrosion to large-scale public infrastructure is very serious. Therefore, we propose an effective An additive for inhibiting freezing and thawing corrosion damage of deicing salt, through the addition of additives to effectively inhibit the destructive damage of deicing salt freezing and thawing corrosion.
