Embodiment Construction
[0018] The road vehicle exhaust gas degradation composite material of the present invention comprises rubber powder, titanium dioxide powder, coupling agent and diluent. The titanium dioxide powder has a photocatalytic function. According to the relationship between the photocatalytic degradation efficiency of the titanium dioxide powder and the particle size, the particle size of the titanium dioxide powder can be selected from 10 nm to 1 μm; according to the roughness of the actual road surface, the particle size of the rubber powder can be selected from 20 to 1 μm. 120 mesh; the coupling agent is one or a mixture of silicon, titanium, aluminum, chromium, zirconium, zinc, and calcium; diluents include water, ethanol, isopropanol, engine oil, One or more of white oil and solvent oil.
[0019] The designed pavement automobile exhaust degradation composite material of the present invention is mainly based on titanium dioxide powder and rubber powder (the consumption on the road...
