Problems solved by technology

[0005] The current anti-icing coatings are often salt deicing agents, which are of a single type and only have a certain effect of lowering the freezing point, and cannot be released stably for a long time. It cannot further soften the ice layer and slow freezing

Abstract

The invention discloses a hydrophobic multifunctional snow-melting agent and a preparation method thereof. The hydrophobic multifunctional snow-melting agent comprises a hydrophobic salts composite snow-melting agent, a hydrophobic composite freezing relieving agent and a hydrophobic composite ice layer softening agent according to the mass ratio of 6-7: 1-2: 1-2; the hydrophobic salts composite snow-melting agent is formed by carrying out slow release treatment and hydrophobic treatment on a salts snow-melting agent successively; the hydrophobic composite freezing relieving agent is formed bycarrying out slow release treatment and hydrophobic treatment on a freezing relieving agent successively; and the hydrophobic composite ice layer softening agent is formed by carrying out slow release treatment and hydrophobic treatment on an ice layer softening agent successively. An ice suppressing coating formed on a road surface by coating has various effects of greatly reducing a freezing point, relieving freezing and softening an ice layer.

Description

technical field [0001] The invention belongs to the technical field of road engineering, and relates to a melting or antifreezing material used on the surface, in particular to a hydrophobic multifunctional deicing agent and a preparation method thereof. Background technique [0002] In the central part of my country, the amount of snowfall in winter is not large and the snow melts quickly. After the snow melts, the continuous low temperature weather will easily lead to the formation of the ice layer. Since the amount of snow is not large, the ice layer will not be too thick, but the ice layer also has a certain hardness. Ordinary methods of spraying salt deicing agent or mechanical deicing consume a lot of manpower and material resources, the deicing effect is not ideal, and it will also cause erosion and damage to the environment. [0003] In recent years, the road surface ice suppression technology that has been widely used is conductive surface technology and heat pipe te...
