According to the statistics of the water-proof society, the asphalt water-proof material occupies more than 65 percent of domestic market in China. The asphalt-based waterproof material mainly comprises a modified asphalt waterproof coiled material, a self-adhesive asphalt waterproof coiled material, an asphalt coating, a felt, an asphalt tile and the like, wherein the hot-melt modified asphalt waterproof coiled material is the waterproof material with the highest occupancy rate due to the advantages of superior performance, wide application, low price and the like, and accounts for over 26 percent in 2017.
The patent inquiry shows that the coating material of the modified asphalt waterproof coiled material generally comprises polymer particles or reclaimed materials and fillers such as matrix asphalt, softening oil, SBS, SBR, rubber powder and the like, and the preparation process generally comprises the following steps: heating asphalt and softening oil to over 160 deg.C, adding high-molecular particles or recovered material, heating to 165-230 deg.C, swelling high-molecular material with colloid mill, and adding filler such as talcum powder and heavy calcium. In the preparation process, the light components in the asphalt and the softening oil can volatilize a large amount of gases such as organic volatile matters, carbon monoxide, sulfur dioxide and the like due to overhigh heating temperature, and the production line cannot realize complete sealing, and the environment-friendly treatment device cannot realize 100 percent waste gas treatment, so that the modified asphalt waterproof coiled material workshop has obvious smell, thereby causing serious threat to the body health of production workers and also causing serious influence on residents living around.
The scheme of reducing the production temperature in the prior art mainly comprises two schemes, one scheme is that a solvent is adopted to pre-dissolve high molecular modifiers such as SBS, SBR and the like, for example, Chinese patent application CN00129156.4, the method can improve the dissolving rate of SBS and can mix with asphalt, but the solvent needs to be separated out, the needed process is complex, the recovery efficiency of the added solvent cannot be guaranteed, and part of the solvent is remained in the modified asphalt, thereby affecting the property of the modified asphalt. Secondly, the low-temperature modification is realized by adopting a mode of activating rubber powder, for example, Chinese patent application CN201610005365.2, in the patent, an inventor carries out pretreatment on the rubber powder by utilizing an ultrasonic energy-gathering mode, the swelling activity of the rubber powder is improved, and the low-temperature modification is realized.

The production temperature is reduced and the product quality is improved while the production efficiency is not reduced.
1. In the prior art, normal pressure distillation and reduced pressure distillation are adopted during the refining of general heavy oil, and the normal pressure distillation is carried out, wherein the normal pressure distillation is gasoline fraction at the temperature of less than 200 ℃; 200 ℃ and 350 ℃ are coal and diesel oil fractions; atmospheric heavy oil fraction at the temperature of more than 350 ℃; performing reduced pressure distillation at 350 ℃ and 500 ℃ to obtain a lubricating oil fraction or a catalytic cracking raw material; vacuum distillation is carried out at the temperature of more than 500 ℃ to obtain a vacuum residue fraction, namely common petroleum asphalt, the grade of the asphalt is divided according to the penetration, tests show that the penetration of the initial vacuum residue fraction is 40-80, the crude oil is different, the process is different, and the grade of the straight-run asphalt is also greatly different, and No. 70, 90 and No. 110 petroleum asphalt used in the market is generally prepared by adopting the refining process, and then normal pressure heavy oil fraction, lubricating oil fraction or recovered lubricating oil, catalytic slurry oil and the like are added into the petroleum asphalt for blending to prepare blended petroleum asphalt with corresponding grade.
