preparation example Construction
[0030] In the present invention, the preparation method of described deoiled bitumen preferably comprises:
[0031] Prepared by solvent deasphalting process.
[0032] The present invention has no special limitation on the source of the deoiled asphalt, which can be prepared according to the above method, or purchased from the market, such as Hengli Petrochemical deoiled asphalt 200#.
[0033] In the present invention, the oily substance is selected from hydrogenated tail oil and / or re-refined oil; the kinematic viscosity of the oily substance at 100°C is preferably 1-10mm 2 / s, more preferably 2-8mm 2 / s, most preferably 3~6mm 2 / s; the flash point of the oily substance is preferably ≥ 260°C; the mass content of aromatics in the oily substance is preferably 65-75%, more preferably 68-72%, and most preferably 70%.
[0034] In the present invention, the hydrogenated oil can be purchased from the market, for example, hydrogenated tail oil from Hengli Petrochemical can be used....
Embodiment 1
[0051] Using deoiled asphalt (penetration at 25°C 2dmm, softening point 110°C), re-refined oil (kinematic viscosity at 100°C 2mm 2 / s, aromatics mass content 67%), SBS modifier (molecular weight 125,000), sulfur (content (purity) > 99%) prepares No. 10 of construction petroleum asphalt, with 150 weight parts of deoiled asphalt, 30 weight parts of back refining oil Mix evenly, heat and stir evenly at 150°C, then add 3 parts by weight of SBS, heat and stir at 170°C until there are no solid particles, add 0.017 parts by weight of sulfur, stir evenly at 170°C, and take 3 hours in total.
[0052] The performance test was carried out on No. 10 construction petroleum asphalt prepared in Example 1 of the present invention, and the test results are shown in Table 1.

Embodiment 2
[0057] Using deoiled asphalt (penetration at 25°C 2dmm, softening point 110°C), re-refined oil (kinematic viscosity at 100°C 2mm 2 / s, aromatics mass content 67%), SBS modifier (molecular weight 125,000), sulfur (content > 99%) prepare No. 10 construction petroleum asphalt, 160 weight parts of deoiled pitch, 20 weight parts of back refining oil are mixed uniformly, Heat and stir at 150°C, then add 2 parts by weight of SBS, heat and stir at 170°C until there are no solid particles, add 0.017 parts by weight of sulfur, and stir at 170°C for a total of 3 hours.
[0058] The performance test was carried out on the construction petroleum asphalt No. 10 prepared in Example 2 of the present invention, and the test results are shown in Table 2.
