Abstract

The invention discloses a road coating capable of adsorbing tail gas as well as a preparation method and an application thereof. The road coating material is prepared from raw materials in parts by weight as follows: 42-50 parts of seaweed clay, 17-25 parts of vermiculite, 5-13 parts of cocamidopropyl betaine, 11-19 parts of triethanolamine and 3-7 parts of citric acid. The road coating material takes the seaweed clay and the vermiculite as main raw materials, after treatment with other substances, excellent characteristics of all raw materials are reasonably utilized, and the road coating can purify NOX, HC compounds, CO and other harmful gas in the air, has a certain effect on absorbing greenhouse gas, namely, CO2 and significantly improves the road environment. The road coating is pollution-free and high in mechanical and chemical stability and durability. The road coating is simple and convenient to construct and has excellent pavement performance, the construction process is simple, raw materials are non-toxic and harmless, and the road coating has great social benefit in improving road use quality and protecting the environment.

Description

technical field [0001] The invention relates to the technical field of road materials, in particular to a road coating for absorbing tail gas, a preparation method and application thereof. Background technique [0002] With the rapid increase of the number of automobiles, the environmental pollution caused by automobile exhaust is becoming more and more serious, and the environment around the road is constantly deteriorating. The main harmful components of automobile exhaust are NO X , HC compounds, CO, particulate matter, etc. More than 40% NO in air pollutants X , More than 80% of CO and more than 70% of HC compounds are caused by automobile exhaust. Therefore, controlling the environmental pollution caused by automobile exhaust is of great significance to improving the quality of road use and protecting the environment. For the purification of automobile exhaust, in the field of roads, the technology of coating a layer of air-purifying materials on the surface of aspha...
