Abstract

The invention discloses a method for prolonging playing time of snow melting function of an environmental-protection snow-melting agent. The environmental-protection snow-melting agent and solid-state polydimethylsiloxane are placed in the same airtight space, it is guaranteed that the environmental-protection snow-melting agent and solid-state polydimethylsiloxane are not in contact and inter-amalgamation, the airtight space is heated, the polydimethylsiloxane is evaporated and coated on the surface of the snow-melting agent, and therefore the environmental-protection snow melting agent coated with the polydimethylsiloxane is formed. A polydimethylsiloxane plated film is formed on the environmental-protection snow melting agent in a vapor plating mode, the direct contact of the environmental-protection snow melting agent and the ground is avoided, and therefore the corrosion on metal and concrete and the harm on surrounding vegetation and soil can be greatly lowered; due to the hydrophobicity of the polydimethylsiloxane, the speed of contact between water penetrating through a PDMS layer and the coated environmental-protection snow melting agent can be slowed down, water absorption of the PDMS layer is slow, melting of the coated environmental-protection snow melting agent is slow, and the reaction time of the environmental-protection snow melting agent is prolonged.

Description

Technical field [0001] The invention involves the field of transportation and environmental safety, which is specifically a way to extend the time -friendly snow melting agent to play the time of snow melting. Background technique [0002] Winter snowfall and icing often cause inconvenience to cities and transportation, and can easily cause traffic accidents, especially on highways, it is likely that the highway is forced to be closed and stopped due to snow or icing, causing causing itGreat economic losses.At present, the methods of removing snow and snow are mainly three types: artificial snow removal, mechanical snow removal, and snow -blending snow removal agent. Among them, snow melting agents are widely used due to the advantages of simple methods, easy operation, and fast snow melting speed. [0003] The raw materials of traditional sodium chloride -chloride -based raw materials are cheap and easy to get, and the snow melting effect is good. However, it has serious corrosi...
