Description

A kind of asphalt material preparation method with decomposing automobile exhaust function
Technical field
The invention belongs to pitch processing technique fields, and in particular to a kind of asphalt material with decomposing automobile exhaust function Preparation method.
Background technology
It is well known that vehicle exhaust has typical penetrating odor, the NO in tail gas2It is changed into HNO3 Afterwards to eyes Stimulation is generated, in addition, the substance of acute Eye irritation can be caused to further include the substances such as methacrylaldehyde, acetaldehyde, formaldehyde in vehicle exhaust, The vehicle exhaust of higher concentration easily causes expiratory dyspnea, sore-throat, headache, cough simultaneously, and severe patient can also induce asthma.People The respiratory system of body is the organ most directly contacted with vehicle exhaust, and Long Term Contact vehicle exhaust can make respiratory system immunity It reduces, the thing followed is the breaking-out of the relevant diseases such as bronchitis, chronic bronchitis.In addition human body is immunized in vehicle exhaust System, reproductive system have harmful effect, more have scholar to think that vehicle exhaust has mutagenesis and carcinogenic effect.At present for automobile The control techniques of tail gas is substantially focused on the control of exhaust emissions and two aspect of purification of tail gas itself, such as：Combustion chamber The engine interiors purified treatment measures such as ignition advance angle, exhaust gas recycling, washing, tail gas catalytic purification are postponed in system optimization The external engines tail gas clean-up measure such as device.
Invention content
In view of the above-mentioned problems, the present invention is intended to provide a kind of asphalt material preparation side with decomposing automobile exhaust function Method opens up a new road for the purification of vehicle exhaust, while again there is good vehicle exhaust to decompose catalytic effect.
The invention is realized by the following technical scheme：
A kind of asphalt material preparation method with decomposing automobile exhaust function, which is characterized in that including descending step：
（1）It will be filtered, and in 90-110oC with after sodium hydroxide solution immersion 10-30min 20-30 parts of zeolites in parts by weight Then 5-10 part magnesia are added in lower drying, uniformly mixed to be placed in Muffle furnace, and 3-5h is roasted at 380-420 DEG C, obtain through Magnesium oxide modified zeolite；
（2）By step（1）Gains, 20-30 a part nano-titanium dioxide are dispersed in 400-500 parts of deionized waters, room temperature, After stirring 1-2h under 250-350 r/min speed conditions, it is warming up to 65-75 DEG C, is slowly added to 30-50 parts of octadecyl trimethyls Ammonium chloride solution continues to stir 3-5h, stands naturally to room temperature, reaction solution is filtered, and obtains solid precipitation, precipitation is distilled Water washing 2-3 times is fully dried and is ground under the conditions of 80-100 DEG C, and 150-250 mesh sieve is crossed；
（3）80-120 parts of matrix pitches are melted in 120-160 DEG C of baking oven, pitch is transferred on electrothermal furnace after melting and is protected 150-160 DEG C of temperature is held, 5-8 parts of aromatic naphtha are added, and turn in 1500-2500r/min using high speed shearing emulsification blender Speed is lower to carry out shear agitation 10-30min；
（4）By step（2）Gains are slowly added to step in multiple times（3）In gains, wait for after all adding, by rotating speed It is adjusted to 3500-4500r/min, continues to stir 1-2h at a temperature of 150-160 DEG C, gains is made to be dispersed in matrix drip In blueness.
Further, step（1）The concentration of sodium hydroxide solution is 5-10%.
Further, step（2）Described in octadecyltrimethylammonium chloride solution concentration be 30-50%.
Further, step（3）Described in matrix pitch be heavy traffic bitumen A H-90.
Further, which, can be in surface spraying by step in pavement usage（2）The nanometer titanium dioxide of gained Titanium modified zeolite suspension, specific method are to wait for naturally dry by the suspension spray on the asphalt material road surface Afterwards, it sprays, sprays 2-4 times altogether again.
Beneficial effects of the present invention：After zeolite soaking with sodium hydroxide, one be blocked in zeolite cavity can be dissolved A little impurity, dredging hole cavities road, further widen the useful space in duct, enhance the adsorption capacity of zeolite；Then using roasting Magnesia is directly dispersing on natural zeolite by the method for burning, increases its specific surface area, so that it is obtained very alkaline active position and is protected Microcellular structure is stayed, to improve adsorption capacity of the zeolite to vehicle exhaust ammonia nitrogen compound；Be modified zeolite have it is good Nano-titanium dioxide is adsorbed in its duct by absorption property, after octadecyltrimethylammonium chloride solution is added, organic examination The cation of agent can swap reaction with zeolite surface cation, can replace organic cation to modified zeolite surface, this Sample zeolite, nano-titanium dioxide entirety surface be attached to a large amount of organic cations so that zeolite mixture is by original hydrophilic It is changed into hydrophobic, oleophylic, is conducive to its merging with bitumen base, while the addition for the reagent that organises significantly effectively improves boiling The phenomenon that stone particle aggregation, help further to be doped to asphaltene molecule it, enhance between pitch and zeolite nano-titanium dioxide Interaction, significantly improve the pavement performance of composite material；After zeolite mixture is mixed with pitch, viscosity increases, and easily occurs Segregation phenomenon, aromatic naphtha, which is added, to be conducive to improve pitch and adulterates nothing to increase fragrance point content, play stabilizer function Compatibility；Nano-titanium dioxide is a kind of excellent catalyst, can be under illumination condition by the overwhelming majority in vehicle exhaust Pollutant aoxidizes, and ultimately generates carbon dioxide and water, it is combined with modified zeolite carrier, modified zeolite carrier is excellent Adsorption effect can adsorb the vehicle exhaust in large quantity of air, while the nano-titanium dioxide decomposed tail gas being attached on zeolite, The decomposition efficiency and utilization rate for substantially increasing nano-titanium dioxide, when using with road surface, and the asphalt material surface again Zeolite tio_2 suspension is sprayed, has further consolidated the asphalt material absorption degradation effect, vehicle exhaust has been effectively relieved Seriously polluted problem.
