Abstract
The invention discloses an asphalt composition and a preparation method thereof. The asphalt composition is prepared from the following raw materials: asphalt, ethanol, acrylic resin, glycerol, rubber powder, organic pigments, sodium dodecyl sulfate, p-phenylenediamine, pentaerythritol ester and dimethylaniline. The preparation method comprises the following steps: fully mixing acrylic resin and rubber powder; adding ethanol, glycerol and sodium dodecyl sulfate; after fully stirring and mixing, putting into asphalt which is heated to 200-220 DEG C; maintaining temperature; adding a mixture of organic pigment and pentaerythritol; and finally, adding p-phenylenediamine and dimethylaniline and fully mixing to obtain the asphalt composition. The preparation method disclosed by the invention is simple, and the prepared asphalt composition is good in anti-aging performance. According to the asphalt composition disclosed by the invention, the anti-aging performance of asphalt is improved by adding rubber powder and dimethylaniline, and the viscosity of asphalt is improved and the elasticity is well recovered by adding acrylic resin, organic pigments, sodium dodecyl sulfate and p-phenylenediamine.
Description
Technical field
The present invention relates to a kind of bituminous composition and preparation method thereof, belong to industrial chemical technical field.
Background technology
Pitch is usually used in preparing the material of paving the way with roof Material.In road construction and road pavement industry, ripe practical method is fluid asphalt coating aggregate (aggregate) material utilizing heat, such as sand, gravel, rubble or its mixture, when its also heat, the material of coating is sprawled as homogeneous layer on roadbed or the previous road built, and by heavy road roller roll extrusion by homogeneous layer compacting, to form ganoid road.
The combination of pitch and aggregate materials such as sand, gravel, rubble or its mixture is referred to as " bituminous concrete ".Pitch, is also referred to as " bituminous concrete tackiness agent ", normally a kind of liquid adhesive containing bituminous matter, resin and oils.It can be naturally occurring, also can be (such as, by the fractionation or by precipitation (such as utilizing propane)) that obtain from the residue of crude oil, or obtain afterwards at crude refinement processes (such as cracking).Pitch comprises the hydro carbons with high asphalt content (such as, 12 % by weight or higher) usually.Pitch also can through some further process (such as blowing), thus make pitch component through the oxidation of peroxide (as air) or chemical composition (as phosphoric acid).
Along with the fast development of highway in China carrier, oil and asphalt price rise steadily, and bituminous coat project investment increases greatly.In addition, the vehicle in transport by road maximizes, heavily loaded, overloading is more and more serious, and highroad is more and more higher in high-temperature stability, low-temperature cracking-resistance, resistance to deterioration and life requirement.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, bituminous composition providing a kind of resistance to deterioration good and preparation method thereof.
Technical scheme of the present invention is as follows:
