Problems solved by technology

On the one hand, this technology only degrades the nitrogen oxides in the exhaust gas. On the other hand, there will inevitably be a large amount of vehicle exhaust gas that cannot be degraded by contact and will quickly escape into the atmosphere. The effect of exhaust gas treatment is limited.

Abstract

The invention provides a pavement material capable of degrading automobile exhaust and its preparation method. The method of the invention is to use a newly prepared powder material and water, cement, standard sand, etc. to make cement mortar, and then mix it with petroleum asphalt. It is obtained that the material has excellent adsorption capacity, can quickly absorb and degrade automobile exhaust gas (including carbon monoxide, carbon dioxide, nitrogen oxides, hydrocarbons, etc.), and effectively prevent and control automobile exhaust pollution.

Description

technical field [0001] The invention relates to the technical field of environmental protection materials, in particular to a pavement material capable of degrading automobile exhaust and a preparation method thereof. Background technique [0002] In recent years, with the economic development and the increase of national income, the car ownership has increased dramatically. While automobiles bring convenience to daily life, they also bring serious automobile exhaust pollution, which has become one of the main sources of air pollution. Automobile exhaust contains a large number of harmful substances, including carbon monoxide, carbon dioxide, nitrogen oxides, hydrocarbons and solid suspended particles. [0003] At present, preventive treatment and purification are usually used for automobile exhaust, that is, treatment is carried out before the exhaust gas is discharged from the vehicle, and there are relatively few researches on the treatment technology after the exhaust g...
