Problems solved by technology

[0002] At present, the road has asphalt, colored asphalt, cement and other road surfaces, and the road surface is easy to stick to ice and snow, and it is difficult to remove
Especially when it freezes in winter, sticky snow is more difficult to remove in a short time, causing traffic jams and accidents.
Nowadays, the main methods for people to remove ice and snow on the road are to use deicing agents and mechanical methods to remove them. Among them, the characteristics of deicing agents can be sprayed on a large area, and the ice and snow can be quickly removed without affecting the traffic of vehicles. If it is used for a long time, it will cause irreversible damage to the environment. , and mechanical shoveling and snow removal, although there is no adverse effect on the environment, but the operation time is long, which affects the normal traffic of vehicles. Generally, the snow removal work needs to be started after the snow. , frequent traffic accidents cause traffic jams

Embodiment 1

[0018] On the original road surface of new and old asphalt, use an asphalt spreader to evenly spray a layer of surface anti-adhesive layer combination group with a thickness of 1-5mm. Immediately roll it with a road compactor so that the powder is embedded in the anti-sticking layer on the surface, and the construction is completed. The hydrophobic powder can be paved with a paver.

[0019] Among them, the old asphalt pavement should be cleaned with a sweeper, vacuum cleaner, or blower first; if the pavement is seriously damaged, the modified asphalt should be sprayed with a coating layer of more than 5mm and the pits should be filled, and then a layer of glass fiber cloth should be spread. A surface release layer can be applied with one coat of modified bitumen. The hydrophobic powder may be rosin powder or the like. Composition mass ratio of surface release layer composition: fluorinated asphalt 40-60%, SBS6-8%, EVA3-4%, high temperature vulcanized silicone rubber compound...

Embodiment 2

[0021] 10-30% of the total mass of the blend of silicone rubber and acrylate glue was added to the composition system of the surface release layer composition in Example 1 to form a new surface release layer composition. Other fluorosilicone blends may also be used. Then add 20-30% rubber powder to the modified asphalt undercoating agent to make a new undercoating agent layer, and apply it on the new and old asphalt pavement with a thickness of 5-10mm to make a long-life non-stick ice and snow road surface.

Embodiment 3

[0023] After cleaning the road surface on the new and old asphalt and cement road surfaces, and filling up the pits and ditches, use a road marking sprayer to continuously spray a layer of surface anti-sticking layer with a thickness of less than 5mm. Adding hydrophobic pigments to the anti-sticking layer on the surface can make pavements or road markings of various colors. The composition of the surface anti-adhesive layer: 20-30% of silicone modified acrylate, 20-30% of acrylic grafted rubber, 5-10% of fluorinated carbon powder below 0.5 μm, and modified rosin below 3% of hydrophobic fiber length 2% below 5mm, and the rest are conventional fillers such as hydrophobic fillers such as montmorillonite. The production and preparation process of the surface anti-sticking layer composition, add the film-forming material into the batching tank, add appropriate amount of butyl acetate and ethylene glycol butyl ether, stir at high speed to disperse, stir at low speed and then add var...

Abstract

The invention is an ice and snow-antitacking road surface and the surface anti- tacking layer combination and constructing method thereof, relating to the road construction field, and its technical solution: making a hydrophobic wearable antitacking coating with enough friction coefficient, mainly comprising organic fluorine and silicon materials or fluorine and silicon-containing modified graft organic polymers, and fillings including hydrophobic nano powders, hydrophobic routine fillings and aggregates including hydrophobic natural fibers and artificial fibers, as well as antiskid materials, and connecting the coating through lower gel layer together with the original road surface. And the road surface can be made into color road surface.

Description

technical field [0001] The invention relates to the field of road construction, and more particularly relates to the construction of a road surface anti-sticking ice and snow and the composition of the road surface anti-sticking layer.
