Embodiment Construction

[0019] The present invention will be further described below in conjunction with embodiment:

[0020] According to the table below, select paraffin oil, naphthenic oil, aromatic oil, coumarone resin, pine tar as softener, SBS, SBR, EVA, PE as modifier, carbon black, white carbon black, attapulgite, Clay, calcium carbonate powder, and calcium carbonate particles are used as fillers, water, methanol, and ethanol are used as fluxes, and toluene, cyclohexane, gasoline, ethylbenzene, and hexane are used as solvents.

[0021] Weigh the mass of base asphalt to 100g, introduce the solvent into a closed mixing tank, control the reaction temperature of a stage at 20-80°C, and stir at a speed of 100-800rpm, add base asphalt, softener and modifier in sequence for mixing, and the mixing time is 5 -12h, the toluene in the material is extracted after mixing, the second stage reaction temperature is raised to 120-160°C, filler and flux are added for mixing, the mixing time is 15-30min, the te...

Abstract

The invention discloses an asphalt composition and a preparation method thereof. The asphalt composition is prepared from the following components in parts by mass: based on 100 parts by mass of matrix asphalt, 5 to 70 parts of softener, 5 to 200 parts of modifier, 5 to 150 parts of filler and 1 to 10 parts of fluxing agent. The asphalt composition disclosed by the invention has the advantages ofgood storage stability, good fuel and oil solubility resistance and corrosion resistance, and good usability at high and low temperatures.

Description

technical field [0001] The invention relates to the technical field of asphalt composition and its preparation method, in particular to an asphalt composition and its preparation method. Background technique [0002] Asphalt in the traditional sense is a colloidal substance composed of resin-wrapped asphaltene molecular groups, which presents a strong oily state (that is, petroleum quality). Colloids are divided into sol (mainly refers to liquid density) and jelly (mainly refers to solid density), depending on the equilibrium state between its components. For bitumen, the equilibrium of the two states depends on the interaction between asphaltenes and resins and is strongly influenced by the external temperature. In fact, the increase of asphalt temperature breaks its jelly state, and the asphalt molecular clusters evolve into a sol state. Therefore, an important characteristic of asphalt is that it is solid or semi-solid at room temperature, but it is very easy to dissolv...
