ENVIRONMENTALLY-FRIENDLY IMPROVED DEICER COMPOSITIONS

摘要

The present disclosure relates generally to deicer compositions comprising a liquid deicing agent which is as an aqueous solution of a deicing salt and additives that provide reduced corrosiveness with reduced biochemical oxygen demand. Aspects of the disclosure are particularly directed to use of the deicer composition as a liquid deicer or an anti-icer. The deicer composition can further include a solid deicing agent such as sodium chloride, where the liquid deicing agent and additive form a pre-wetting agent when mixed with the solid deicing agent to form a pre-wetted deicer.

主权项

1. A deicer composition comprising:
a. A liquid deicing agent, wherein the liquid deicing agent comprises an aqueous solution of a deicing salt or liquid bittern; and b. A corrosion inhibiting additive, wherein the additive comprises gluconic acid, saccharic acid, gluconate salts, saccharate salts or combinations thereof; and c. A viscosifying additive, wherein the additive comprises xanthan gum, cellulose gum, polyvinyl pyrrolidone, acrylic acid polymers, cross linked acrylic polymers, polyether polyols, sodium carboxymethyl cellulose, hydroxyethyl cellulose, carboxymethyl hydroxypropyl guar, hydroxypropyl guar, polyanionic cellulose, pregelatinized crosslinked starch such as hydroxypropyl distarch phosphate and distarch phosphate, scleroglucan, pectin or combinations thereof.
