Abstract
The invention relates to an infrared powder asphalt mixture and a preparation method thereof. The infrared powder asphalt mixture is composed of asphalt, mineral aggregate and infrared powder, and is characterized in that the infrared powder accounts for 4-15 wt% of the infrared powder asphalt mixture. The preparation method comprises the following steps: (1) weighing treated infrared powder base material and oxide, and uniformly mixing; (2) sintering the mixture obtained in the step (1) at 1000-1200 DEG C for 2-4 hours; (3) respectively carrying out primary crushing, secondary crushing and superfine grinding on the infrared powder crystal obtained in the step (2); (4) putting the infrared powder in a stirrer, adding the mineral aggregate, and carrying out dry mixing for at least 15 minutes; and (5) adding the asphalt, and carrying out wet mixing for 0.5-1 hour. The infrared powder asphalt mixture has favorable infrared radiation characteristic and heat insulation, and can effectively lower the pavement temperature and relieve the urban heat island effect.
Description
Technical field
The present invention relates to material engineering field, be specifically related to a kind of using the asphalt mixture and preparation method thereof of infrared powder as modified formula.
Background technology
Well-known bituminous pavement has the advantages such as comfort level of better driving a vehicle, short construction period and maintenance cost are few compared to concrete road surface, but summer bituminous pavement be subject to temperatures involved and easily occur gathering around the caloric disease evils such as bag, cracking, bellding, have a strong impact on service life of road surface and travel safety, the heat energy that road surface is gathered simultaneously also can cause the rising of free air temperature, affects human settlement environment in city.Infrared radiant material is a kind of new function material risen the thirties in 20th century, obtain in heating and energy saving fields such as health care, military affairs, construction work, Industrial Stoves and apply extremely widely, 2010, the people such as National and Capodistrian University of Athens Synnefa Afroditi have developed a kind of thin layer colour pitch, utilize it to the high reverse--bias performance of radiation, reduce bituminous pavement skin temperature in summer, to reach the object of alleviating urban heat island effect, better performances, but it selects industrial chemicals to there is the problem of high cost as the base-material of infrared radiant material.
Summary of the invention
The object of this invention is to provide that a kind of technique is simple, cost is low and have from infrared powder asphalt of heat dispersion and preparation method thereof.The present invention with more than 90% industrial residue for base-material synthesizes infrared powder be applied to road engineering, utilize powder at the high radiation character of air infrared window, the heat that bituminous pavement is accumulated is emitted to the outer space with ultrared form, thus reaches the object of road surface cooling.
Technical scheme:
A kind of infrared powder asphalt, be made up of pitch, mineral aggregate and infrared powder, the weight ratio of described infrared powder in infrared powder asphalt is 4-15%, described infrared powder ways added is: be spiked in asphalt with infrared powder Substitute For Partial mineral aggregate as filler, described infrared powder with industrial residue and raw mineral materials for base-material, with oxide compound for mix composition outward, adopt high temperature sintering and super-refinement to mill infrared powder that technique formed, in described infrared powder, material composition weight percent is:
