A superhydrophobic asphalt pavement anti-icing coating and preparation method thereof

Abstract

The invention belongs to the technical field of asphalt concrete pavement coating design, and relates to a super-hydrophobic asphalt pavement anti-icing coating and a preparation method thereof. layer and anti-wear filler dispersed in the functional layer; the functional layer is a low surface energy material; the slurry of the adhesive layer is formulated from epoxy resin 128, amine curing agent and epoxy toughener 277, the functional layer The slurry is prepared from MHX-1107 hydrogen-containing silicone oil, γ-aminopropyltriethoxysilane, dibutyltin dilaurate, absolute ethanol, ammonia water and deionized water; the anti-wear filler is evenly dispersed in the slurry of the functional layer In the body; the performance of the superhydrophobic asphalt pavement anti-icing coating of the present invention can fully meet the requirements of superhydrophobic, anti-icing, wear resistance and high friction coefficient.

Description

technical field [0001] The invention belongs to the technical field of asphalt concrete pavement coating design, and relates to an environmentally friendly, economical and simple superhydrophobic asphalt pavement anti-icing coating and a preparation method thereof. Background technique [0002] In most parts of our country, the road surface will freeze in winter, and the road surface after freezing will have a huge impact on traffic, human production and life. On December 4, 2017, in Xi'an City, Shaanxi Province, during the sprinkling process of the road surface, the water could not be quickly drained from the road surface, which caused the road surface to freeze, resulting in a series of collisions of 38 vehicles, causing many casualties and a large number of economic losses. On January 10, 2008, my country's Northwest, Southwest, Central Plains, and South China successively experienced the largest and longest-lasting rainy and snowy weather, which had an extremely adverse ...

On December 4, 2017, in Xi'an City, Shaanxi Province, during the sprinkling process of the road surface, the water could not be quickly drained from the road surface, which caused the road surface to freeze, resulting in a series of collisions of 38 vehicles, causing many casualties and a large amount of economic losses.

Due to the rough surface of asphalt concrete, after the water drips, the heat releases and freezes, and the ice and rain concrete on the road interpenetrates each other to form a stable physical connection, which makes deicing difficult

(5) Indirect damage, the use of deicing salt after the pavement is frozen will cause greater damage to the pavement structure

However, there are few reports on the application of superhydrophobic materials in road anti-icing and deicing, and it is still in the initial stage of exploration.

In addition, the preparation process of super-hydrophobic materials is complex and expensive. Whether it is the construction of rough surfaces or the cost of fluorinating agents used to reduce the surface energy of materials, the cost is relatively high. The large-scale use of super-hydrophobic coatings is not suitable for the market in my country's road industry, so In order to be used in the road field of our country, it is necessary to reduce the cost of the material without reducing the performance of the material, simplify the preparation process of the material and be environmentally friendly.
