Abstract

The invention discloses an emulsified asphalt material for purifying automobile tail gas and a preparation method thereof. The emulsified asphalt material includes the following raw material components in parts by weight: base asphalt: 100 parts; first surfactant: 1-10 parts; water: 10-60 parts; asphalt modifier: 1-20 parts; Modified porous carbon material: 1 to 20 parts; the asphalt modifier is based on lanthanide metal oxides as a carrier, and transition metal oxides as catalytic active components; the amount of transition metal is the mass of lanthanide metal oxides 5% to 100% of that; the modified porous carbon material is a porous carbon material modified by the second surfactant. The emulsified asphalt material of the present invention is mainly used for the maintenance of expressway asphalt pavement, wherein the asphalt modifier in the emulsified asphalt material has the function of purifying the automobile exhaust pollutants on the road surface, and can be Car exhaust is purified.

Description

technical field [0001] The invention relates to an emulsified asphalt material and a preparation method thereof, in particular to an emulsified asphalt material for purifying automobile tail gas and a preparation method thereof. Background technique [0002] With the rapid development of China's economy, the per capita car ownership of Chinese residents continues to rise. Although the current emergence of new energy vehicles including lithium-ion electric vehicles and hydrogen vehicles continues to impact traditional fuel vehicles, but in the future for a long time In 2019, fuel vehicles will still occupy a large share of the motor vehicle market, so the problem of vehicle exhaust pollution will still exist for a long time. In the case of fewer vehicles, the self-purification ability of the atmosphere can still purify low-concentration automobile exhaust, but with the increase of traffic volume, especially when traffic congestion becomes normal, the self-purification ability...
