Problems solved by technology

At present, passive snow-melting technology is mainly used for deicing and snow-melting roads: spreading snow-melting agents, anti-skid materials, mechanical cleaning, etc. These technologies have certain problems: spreading salts or environmentally friendly snow-melting agents will cause serious pollution to the environment and road surfaces, and the efficiency of deicing snow is relatively low. Low; artificial or mechanical snow removal, dark ice cannot be removed within the depth of the structure, and the cost is high, the operation is dangerous, and the efficiency is not high
The research found that this patent ha...

Abstract

The invention discloses a slow-release three-component road de-icing and snow-melting coating and a preparation method thereof. The coating comprises a film-forming component A, a cementing component B and an ice inhibiting component C, wherein the ratio of the mass part of the film-forming component A, the cementing component B and the modified ice inhibiting component C is 100:(1-2):(2.4-4). The preparation method comprises the steps of preparing the film-forming component A; preparing the cementing component B; preparing the ice inhibiting component C; modifying the ice inhibiting component C; and preparing the slow-release three-component road de-icing snow-melting coating. The coating is solidified on the road surface and in the structural depth of the coating to form a good-adhesive de-icing snow-melting film layer after spraying, the ice inhibiting component C of the film layer actively releases an ice point inhibitor to prevent hydrogen bond association between water molecules and reduce the ice point to (-4)-(-8) DEG C, thereby achieving the effect of active de-icing and snow melting, and meanwhile, as the ice point inhibitor has long-acting slow-release performance due to the adoption of slow release control technology, the coating can achieve the effect of active snow melting and de-icing in a winter.

Description

technical field [0001] The invention relates to a coating and a preparation method thereof, in particular to a slow-release three-component road surface deicing and snow-melting coating and a preparation method thereof, belonging to the technical field of chemical coatings. Background technique [0002] Snowfall and ice accumulation on roads in winter have a serious impact on smooth roads and driving safety. When there is ice and snow on the asphalt road, the adhesion coefficient of the road surface is only 1 / 4 ~ 1 / 3 of that of the dry road surface. The sharply reduced adhesion coefficient seriously affects the braking and steering operations of the vehicle, which easily induces traffic accidents and brings life and property to the people. loss. In order to ensure smooth road surface and driving safety, avoid or reduce traffic accidents, improve road capacity and operational efficiency, measures must be taken to remove ice and snow from the road surface. At present, passiv...
