Abstract

The invention discloses a method for prolonging the snow-melting action time of the environmental-friendly snow-melting agent, which is to place the environmental-friendly snow-melting agent and solid polydimethylsiloxane in the same closed space, and ensure that the two do not contact and melt together, and then heat and seal The temperature in the space causes the polydimethylsiloxane to evaporate and cover the surface of the environmentally friendly snow melting agent, thereby forming an environmentally friendly snow melting agent coated with a polydimethylsiloxane coating. Invented to vapor-deposit polydimethylsiloxane coating on the environmental protection deicing agent, which avoids the direct contact between the environmental deicing agent and the ground, thereby greatly reducing its corrosion to metal and concrete and the damage to surrounding vegetation and soil; and because The hydrophobicity of polydimethylsiloxane (PDMS) can slow down the contact speed of water passing through the PDMS layer and the coated environmentally friendly snow-melting agent. The PDMS layer absorbs water slowly, making the coated environmentally friendly snow-melting agent melt slowly. Thereby prolonging the action time of the environmental protection deicing agent.

Description

technical field [0001] The invention relates to the field of traffic environment safety, in particular to a method for prolonging the snow-melting action time of an environment-friendly deicing agent. Background technique [0002] Snowfall and icing in winter often bring inconvenience to cities and transportation, and easily cause traffic accidents, especially on expressways, which are likely to be forced to close due to snow or icing, resulting in huge economic loss. At present, there are three main methods of deicing and snow melting: manual snow removal, mechanical snow removal, and snow melting agent snow removal. Among them, snow melting agent is widely used because of its simple method, easy operation, and fast snow melting speed. [0003] Traditional chlorine-salt deicing agents based on sodium chloride have cheap and easy-to-obtain raw materials and good snow-melting effects, but they are severely corrosive to metals and concrete, and are also harmful to vegetation ...
