Anti-freezing agent as well as preparation method and application thereof

Abstract

The invention discloses an anti-freezing agent and a preparation method and application thereof, and belongs to the technical field of anti-freezing of road surfaces in cold and cold mountainous areas, the anti-freezing agent is prepared from the following raw materials in parts by mass: 460-560 parts of a composite salt saturated solution, 60-80 parts of a corrosion inhibitor, 130-165 parts of a hydrophobic active agent and 230-280 parts of a wrapping material. Composite salt in the anti-freezing agent is screened with the solubility of single-component salt and the phase transformation point of a saturated solution as indexes, and then based on the three-component simplex centroid design thought in mixed material design, the proportion combination with the maximum target value is selected with the ice melting amount as the index; salinization substances are controlled to be uniformly released within the service life of a pavement, the use durability of the pavement is guaranteed, the pavement is used for preparing anti-freezing concrete, the anti-freezing asphalt concrete which is suitable for high and cold areas and has excellent high-temperature performance and water stability is obtained, and the problems of road traffic safety and the like in the high and cold areas can be solved.

Description

Technical field [0001] The present invention relates to the field of anti-icing technology on the pavement of alpine mountainous areas, specifically relates to an anti-icing agent and preparation method and application thereof. Background [0002] Most of the alpine mountains in western Sichuan belong to alpine and high-altitude areas, with strong ultraviolet rays, large temperature differences in sunshine, unpredictable weather, and unfavorable weather conditions such as rain and fog that occur at any time. High altitude and large temperature differences between day and night lead to foggy and icy weather in autumn and winter, and winter ice and saliva ice sections seriously threaten the safety of drivers. [0003] Due to the high air humidity, the road surface in the alpine area is very easy to form ice on the asphalt pavement, causing huge casualties and property losses to the highway, which has become a technical problem plaguing the western transportation department. The ha...

Problems solved by technology

When the temperature rises during the day, the condensed ice on the road melts into water, but the melted ice water is not removed from the road in time. In addition, due to the low temperature and high humidity, it cannot evaporate and remains on the road. When the temperature drops suddenly, the melted ice water condenses into ice again, reducing the anti-skid coefficient of the road surface, resulting in poor braking stability and steering operation stability of the vehicle, and causing traffic accidents

At present, the mixing method of anti-icing asphalt mixture is mostly hot-mixing type. Since the annual average minimum temperature in the alpine region of western Sichuan will reach -5°C, the construction efficiency of hot-mix asphalt mixture is low when paving and repairing pavement under this temperature environment in winter. , traffic pressure and many other disadvantages
