Abstract

The invention discloses an automobile exhaust degenerating material as well as the application thereof, and relates to an environment-friendly material as well as the application thereof. The invention solves the problems existing in prior automobile exhaust degenerating material that the application scope is small, the cost is high, and the manufacture method is complicate. The automobile exhaust degenerating material of the invention is composed of a nanometer titanium dioxide photocatalyst and a binder by the weight ratio of (1-2):20. The automobile exhaust degenerating material of the invention is used for degrading the automobile exhaust road surface, wherein, the application method of the automobile exhaust degenerating material is of a spraying method or a spreading method. The automobile exhaust degenerating material has the advantages of strong practicality, simple process, easy construction application, wide application scope, less material dosage per unit area and low cost. The efficiency in degrading toxic gases of HC and CO in the automobile exhaust can reach higher than 70 percent, the automobile exhaust degenerating material of the invention can be recycled, and the degradation degree to toxic gases after the automobile exhaust road surface degraded by the invention is flushed by rain can be still maintained above 60 percent.

Description

technical field [0001] The invention relates to an environment-friendly material and its application. Background technique [0002] Reducing the air pollution caused by motor vehicle exhaust is one of the urgent problems to be solved in many countries. At present, the main measures to solve exhaust pollution in the world have limitations: although administrative control measures such as the "car-free day" tried in several major cities in my country and Beijing's "odd-even number travel" can limit exhaust emissions to a large extent, Improve air quality, but this measure is still in the initial stage of experimentation, and there are still great difficulties in management and control, and it will bring certain difficulties to residents’ travel. It requires a lot of scientific research and funding, and there are certain difficulties in popularization and application. It is a measure that is difficult to work in the short term; although three-way catalysts have been researched a...
