Problems solved by technology

[0004] However, there are certain problems in this kind of materials: the release of antifreeze components in antifreeze materials cannot be well controlled, and the asphalt pavement is exposed to the outside for a long time, and the chlorides in asphalt antifreeze materials are easily released from wind and rain, especially in rainy weather. road outflow
In some areas, the effective release of anti-icing components is insufficient, and the de-icing effect is not obvious.

Abstract

The invention relates to a temperature-control-based anti-freezing material and a preparation method thereof. Hydrophobic treatment is performed on anti-freezing agent core material at first, then theanti-freezing agent core material is thrown into a hydrogel reaction liquid, and the temperature-control-based anti-freezing material is manufactured after a hydrogel is formed on the surface of thecore material. The temperature-control-based anti-freezing material is hydrophobic due to hydrogel shrinkage under the high-temperature condition, and is hydrophilic due to hydrogel swelling at low temperature, and release of the saline content in the anti-freezing material can be controlled in real time according to the external temperature, so that an anti-freezing agent can work normally in winter. Invalid release of the saline content can be prevented for reduced in a high-temperature rainy season, so that the function time limit of the saline content in bituminous pavements is effectivelyincreased, and the service life of the anti-freezing material is prolonged.

Description

technical field [0001] The invention belongs to the technical field of antifreezing and deicing of road pavement, and in particular relates to an antifreezing material based on temperature regulation and a preparation method thereof. Background technique [0002] Transportation is the lifeblood of the national economy and plays an inestimable role in the development of the entire national economy. With the rapid development of economy, road traffic, especially expressways, has become the lifeline of modern cities. However, in most parts of our country, the winter climate is cold, and the adhesion coefficient of vehicle tires is greatly reduced due to ice and snow in winter. The potential danger of traffic accidents is also increasing. In severe cases, traffic is even closed, which brings great inconvenience to people's travel. Seriously affect the daily life of the people. To remove ice and snow on roads in winter, the most common methods used at home and abroad are still ...
