Problems solved by technology

Once the solution is diluted below a critical ion concentration for a specific temperature, ice crystals begin to form in the solution and it is no longer useful as a de-icer.
Chloride salts and brine solutions have numerous problems as road de-icers.
A first problem is that typical brine solutions containing chloride salts do not exhibit useful melting properties below, at the lowest, about −5 deg. F. A second problem is that such brine solutions impact the environment in negative ways.
They may damage the soil and vegetation surrounding the road, in large part because of the salts, they may adversely impact surrounding lakes, rivers, or streams, and the compounds may be absorbed into water supplies.
A final problem is that such brine solutions may exhibit corrosive effects, damaging vehicles on roads as well as the structure of

A. GENERAL OVERVIEW

The de-icing embodiments of the invention discussed below may be used as anti-icing or de-icing agent on surfaces, such as outdoor surfaces, or for pre-wetting of solids or pre-treating of stockpiles of solids to be used as anti-icing or de-icing agents. Any of the compositions described below may be applied to surfaces at varying rates as de-icing compositions.

One embodiment of the invention is a composition for reducing the buildup of snow and ice on outdoor surfaces. In this embodiment, the composition contains a sweetwater (sugar-water) mixture. Another embodiment of the composition of the invention comprises adding a brine solution to the sweetwater mixture. The brine mixture and the sweetwater mixture may be combined in varying amounts to form the composition of the invention. A corrosion inhibitor may also be added to the composition. In addition, a steepwater solubles mixture, which may function partially as a corrosion inhibitor, may be added to the c...

Abstract

A composition for reducing the buildup of snow and ice on a surface. The composition includes a sugar-water mixture having approximately 15 to 80 percent by weight of a sugar solid, wherein the sugar solid contains approximately 2-60 percent by weight of a monosaccharide.

Description

FIELD This invention relates to a de-icing composition and method for reducing the buildup of snow and ice on roads and other outdoor surfaces. More particularly, this invention relates to a de-icing composition and method that exhibits low corrosive affects, has a low eutectic point, and is environmentally safe. BACKGROUND Chloride salts have been applied on roads to inhibit the accumulation of snow and ice for many years. Such chloride salts may be applied to the surface of the road directly in solid form or in admixture with water or some other liquid. Spreaders, for instance, may apply solid or liquid de-icing compositions somewhat evenly over the surface of roads. Other substances, such as sand, may also be applied to the road with the solid or liquid composition having chloride salts to treat the roads and help reduce slipping on the road. Brine solutions that contain high concentrations of earth metal and chloride ions are commonly used for application to roads. As long as...
