内蒙古油砂油减压渣油制备特种沥青的研究

以内蒙古油砂油减压渣油为原料，分别与克拉玛依减压渣油、孤岛减压渣油、辽河减压渣油和胜利减压渣油以不同比例调合，考察制备抛光沥青、油漆石油沥青等特种沥青的可行性。结果表明，油砂油减压渣油与克拉玛依减压渣油以25：75的质量比调合后，可作60号抛光沥青，以30：70质量比调合后，可作3号油漆石油沥青；油砂油减压渣油与孤岛减压渣油以 40 ： 60的质量比调合后，可做60号抛光沥青；油砂油减压渣油与辽河减压渣油、胜利减压渣油调合后，调合沥青不宜作特种沥青。

STUDY ON PREPARING SPECIAL TYPES OF BITUMEN USING VACUUM RESIDUE FROM INNERMONGOLIA OIL SANDS

The vacuum residue (VR) of tar sand oil from Innermongolia oil sands was blended with Karamay VR, Gudao VR, Liaohe VR and Shengli VR respectively to investigate the feasibility of preparing asphalt for special uses, such as polishing asphalt and varnish asphalt. Test results showed that 60# polishing asphalt and 3# varnish asphalt could be obtained by blending tar sand VR and Karamay VR in the mass ratios of 25/75 and 30/70, respectively; 60# polishing asphalt could also be prepared by blending tar sand VR and Gudao VR at the mass ratio of 40/60. However, Liaohe VR and Shengli VR could not be used to blend with tar sand VR for preparing special types of asphalt.
