[0004] However, among the existing deicing agents, traditional deicing agents contain a large amount of chloride ions. Although they have high efficiency in melting snow and ice, they are poor in environmental protection and will cause serious corrosion to concrete, bridges, and road surfaces, and chloride ions will accumulate in soil and water. In the ecological environment around the road, a large number of plants die, and vehicle tires will be corroded, which will reduce the service life; industrial acetate deicing agent is basically non-corrosive to steel bars, etc., but its produ...

Method used

[0101] From the test results in Table 1, it can be seen that the sugar alcohol compositions provided by Examples 1 to 6 of the present invention have low freezing point characteristics, and the freezing point can be reduced to below -30°C. Comparing the data of Example 6 an...

Abstract

The invention provides a sugar alcohol composition as well as a preparation method and application thereof. The sugar alcohol composition comprises penitol, the mass percentage of the penitol in the sugar alcohol composition is 25-70%, the freezing point is lower than -30 DEG C, and the sugar alcohol composition has the characteristics of being green, environment-friendly and non-corrosive, and can be used in snow-melting agents, anti-freezing agents and corrosion inhibitors. The sugar alcohol composition can be prepared from waste liquid such as xylitol mother liquid, the cost is low, the process is simple, a new resource recycling way is provided for the waste liquid generated in sugar alcohol processing, and the mode of resource recycling economy is met. A snow-melting agent prepared on the basis of the sugar alcohol composition has good snow-melting and deicing capabilities, and is safe and environment-friendly. The sugar alcohol composition can be used as an anti-freezing agent, can meet the construction requirements of concrete at low temperature, and improves the early strength of the concrete. The sugar alcohol composition can also be used in a corrosion inhibitor, and can significantly reduce the corrosion of a mixed solution to metals, especially carbon steel.
