Abstract
The present invention relates to vehicle tail gas degradation asphalt for treating tail gas discharged by vehicles. The vehicle tail gas degradation asphalt comprises nanometer titanium dioxide powder and asphalt, wherein titanium dioxide accounts for 5 to 15% of the quality of asphalt. In a preparation method used for preparing the vehicle tail gas degradation asphalt, nanometer titanium dioxide powder which accounts for 5% to 15% of the quality of asphalt is mixed in asphalt of 150 to 180 DGE C and is stirred at the speed not less than 4000 revolutions per minute until the nanometer titanium dioxide powder is dispersed evenly. The degradation function of nanometer titanium dioxide to vehicle tail gas enables the present invention to have the degradation performance of vehicle tail gas. The present invention mixes rutile type nanometer titanium dioxide in anatase type nanometer titanium dioxide, photocatalytic performance can be improved for the commingling of two structures enlarge the intracell defect density of semiconductor oxide and increases the concentration of current carriers, and the amount of electrons (positive holes) of stones is increased. Thereby, the present invention has strong capacity for capturing pollutants.
Description
One, technical field
The present invention relates to a kind of bituminous material and method for making thereof, relate in particular to a kind of pitch and preparation technology thereof with degraded vehicle exhaust function.
Two, background technology
Vehicle exhaust is one of primary pollution source that causes air environmental pollution.At present, at the major measure that emission of automobile wastes is taked, be relevant regulations according to country, the multiple catalyzing reactor is installed on the vapor pipe of automobile, make qualified discharge behind the obnoxious flavour catalyzed degradation.But, along with expanding economy, the increase of car owning amount, even each vehicle exhaust qualified discharge all, total still exist in the popularity the problem that exceeds standard of Pollutant levels.So, must adopt new technological method, reduce the Pollutant levels in the atmosphere, guarantee the quality of air.
Three, technology contents
Technical problem the invention provides a kind of under the prerequisite that guarantees the pitch pavement performance, has the pitch and the preparation technology thereof of motor-vehicle tail-gas degradation property.
A kind of motor-vehicle tail-gas degraded pitch that is used for handler motor vehicle discharging tail gas of technical scheme comprises nanometer titanium dioxide titanium valve and pitch, and titanium dioxide accounts for the 5-15% of asphalt quality.
A kind ofly be used to make above-mentioned motor-vehicle tail-gas degraded bituminous preparation method, 5%～15% the nanometer titanium dioxide titanium valve that accounts for asphalt quality mixed in 150-180 degree centigrade the pitch and stir until being uniformly dispersed with the speed that is not less than 4000 rev/mins.
Technique effect (1) pitch of the present invention is based on asphalt stock, mixes the nanometer titanium dioxide titanium valve therein, and therefore, the present invention can guarantee the pitch pavement performance.Nano titanium oxide makes the present invention have the degradation property of motor-vehicle tail-gas to the Degradation of motor-vehicle tail-gas.When (2) the present invention sneaks into rutile type nano titanic oxide in the nano titanium oxide of Detitanium-ore-type, can improve photocatalysis performance.This be because, owing to mixing of two kinds of structures increased the intracell defect concentration of conductor oxidate, increased the concentration of current carrier, the electronics-number of cavities of stone increases, and has the stronger ability of catching pollutent with the people.(3) the present invention adds molysite, Fe in containing the pitch of titanium dioxide
3+Enter and substitute Ti in the titanium dioxide crystal lattice
4+, because ferro element has polynary valency, so Fe
3+The shallow gesture that can become electronics and hole is simultaneously caught the position, has effectively promoted separating of electronics and hole, and can effectively move to the surface participation light-catalyzed reaction of titanium dioxide, and role is to improve photo-quantum efficiency here.Also has effect on the one hand, Fe
3+Produce staggeredly with the energy level of titanium dioxide, transition just can take place in the less energy of light induced electron absorption like this, and the absorption spectrum red shift can light absorbing scope thereby enlarged, and can improve solar energy utilization rate.(4) in containing the pitch of titanium dioxide, add silicon-dioxide, on the one hand, SiO
2Has network structure, to TiO
2Crystalline-granular texture has stabilization, makes crystal grain diminish and increases in the dispersion of matrix camber and specific surface area and surface imperfection.On the other hand, work as SiO
2Mix TiO
2The time, can form the network structure of Ti-O-Si, make TiO
2Energy gap increase, photoabsorption is moved to the shortwave direction, help semi-conductor photoproduction electronics and hole separate with quantum yield from improving, thereby its photocatalytic activity is higher than pure TiO
2Particle.TiO
2Structure tends towards stability.(5) the method for the invention is mixed the stirring of heated bitumen high speed with the nanometer titanium dioxide titanium valve, titanium dioxide powder is scattered in the pitch, thereby makes the pitch that contains titanium dioxide, makes it have degradation property.(6) use anionic that nano titanium oxide is handled, its surface is had and the bituminous affinity, help the homodisperse of titanium dioxide powder, further improved photocatalysis performance of the present invention and physicals.
