Problems solved by technology

[0004] At present, the road industry is actively researching and adopting various measures (water-retaining pavement, heat-shielding pavement, aggregates with high thermal resistance, etc.) These measures cannot fundamentally alleviate the road surface problems caused by high temperature and effectively reduce the temperature of the road surface
[0005] Now our country has put forward clear requirements for strengthening the prevention and control of motor vehicle pollution. All relevant departments and regions have formulated work plans for motor vehicle pollution emissions and corresponding supporting policies, and implemented various methods to reduce exhaust emissions and treat exhaust emissions. , but as a road directly for vehicles—the structure that is most directly in contact with automobile exhaust has no corresponding effective countermeasures in terms of exhaust gas control, so a coating material that is directly coated on the road surface to degrade exhaust gas will be applied from time to time

Description

technical field [0001] The invention belongs to the technical field of road engineering materials, and in particular relates to a road-use multifunctional coating material capable of both heat insulation and cooling and automobile exhaust treatment and a preparation method thereof. Background technique [0002] As a black pavement material, asphalt mixture has a high absorption rate of sunlight, which leads to a high temperature on the asphalt pavement. The use performance and service life of the road, and the heat of the road surface is continuously released to the outside when the temperature is low at night, which keeps the outside temperature high for a long time, which is also one of the reasons for the urban heat island effect. [0003] Today, with the rapid economic development, the per capita car ownership continues to increase. my country has become the world's largest motor vehicle production and sales country for three consecutive years. Vehicles emit a large amou...
