Description

Technical Field

[0001] The invention relates to the technical field of asphalt processing, and in particular to an on-site processing method for SBS modified asphalt. Background Art

[0002] SBS modified asphalt is made of base asphalt, with a certain proportion of SBS modifier added. SBS is evenly dispersed in the asphalt through shearing, stirring and other methods. At the same time, a certain proportion of exclusive stabilizer is added to form an SBS blend material, and the asphalt is modified using the good physical properties of SBS.

[0003] In the Chinese patent with application number CN200510049048.2, an emulsified SBS modified asphalt and its processing method belong to the technical field of asphalt modification and emulsification processing, including base asphalt, modifier, and emulsion prepared by adding water to the emulsifier, characterized in that the modifier is a solid high molecular polymer thermoplastic rubber SBS (styrene-butadiene-styrene), and the amount of the modifier added to the base asphalt is 1-8% of the weight percentage of the base asphalt; the amount of the emulsion added to the base asphalt is 50-100% of the weight percentage of the base asphalt. The processing method is to first put the solid SBS into the asphalt to obtain the modified asphalt. Then the modified asphalt and the emulsion are synchronously input into the emulsifier for emulsification to obtain the emulsified SBS modified asphalt. The formula design of the present invention is reasonable, which can improve the low temperature resistance, high temperature resistance, elastic recovery ability of the emulsified modified asphalt, enhance the bonding strength, and is suitable for engineering applications such as slurry sealing, micro-surfacing, and adhesive layer.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] Example 1

[0037] See also Figure 1 , a method for processing SBS modified asphalt on site, comprising the following steps:

[0038] S1: The base asphalt is transferred into a rapid heating tank and heated to a molten state, and a plasticizer polyurethane is added, and then transferred into a working stirring tank and an SBS modifier and a tackifier rubber powder are added, and the modifier is heated and stirred to fully swell, and the tackifier and the base asphalt are fully mixed to obtain a mixture A;

[0039] S2: Use high-speed shearing equipment to shear mixture A, and add the anti-aging agent gum ester into it. During the shearing process, the temperature is stably controlled at 182℃-186℃. After the shearing is completed, it is transferred to the development tank and developed at a constant temperature for 6 hours to complete the preparation of on-site modified asphalt.

[0040] In S2, the high-speed shearing device shears the mixture A at a rotation speed of 4000 r / min for 40 minutes, the shearing temperature is 185°C, and the temperature in the development tank is 186°C.

[0041] In S1, the heating temperature of the working stirring tank is 186°C and the stirring time is 14 min.

[0042] The weight ratio of base asphalt to SBS modifier is 25:1, and the weight ratio of base asphalt to tackifier, anti-aging agent and plasticizer is 1000:20:3:12.

[0043] Specifically, when the shear temperature is 185°C, the shear rate is 4000r / min, and the shear time is 40min, the mixed shear quality is optimal. At the same time, the added plasticizer polyurethane, BS modifier, thickener rubber powder and anti-aging agent gum ester can be mixed more fully with the base asphalt, thereby improving the modified quality of SBS modified asphalt. The thickener can increase the viscosity and viscosity of the asphalt, thereby enhancing its coating performance and anti-fluidity. The anti-aging agent can slow down the aging rate of asphalt during use, improve its weather resistance and antioxidant properties, and the plasticizer can improve the plasticity and deformability of the asphalt, improve its plasticity and fluidity during the construction process, and indirectly improve the quality of the asphalt product.

When the shearing cylinder 6 is placed on the placement plate 71, it is in the middle of the circle. When the shearing cylinder 6 is placed on the placement plate 71, the pneumatic telescopic rod A75 is contracted by gravity, and the gas in the pneumatic telescopic rod A75 is squeezed into the pneumatic telescopic rod B, thereby extending the pneumatic telescopic rod B and extending the telescopic plate 77 until the pneumatic telescopic rod A75 is compressed to the extreme.

When the shearing cylinder 6 is placed on the placement plate 71, it is in the middle of the circle. After the shearing cylinder 6 is placed on the placement plate 71, the pneumatic telescopic rod A75 is contracted by gravity, and the gas in the pneumatic telescopic rod A75 is squeezed into the pneumatic telescopic rod B, so that the pneumatic telescopic rod B is extended, and the telescopic plate 77 is extended. During the extension process of the telescopic plate 77, the upper end of the plug-in plate 792 always moves against the lower bottom surface of the placement plate 71 until the plug-in plate 792 is inserted into the plug-in slot 712, thereby playing a supporting role by utilizing the gravity of the shearing cylinder 6 itself and the raw material, improving the stability of the shearing cylinder 6 during the shearing process, and indirectly improving the shearing quality.

[0053] During the shearing process, the top view outline of the positioning cylinder 471 is the stirring range of the stirring plate 472, and the rotation of the shearing cylinder 6 can be displayed in the coordinate axis. With the lifting and lowering of the lifting rod 32, the mixture A at different depths in the shearing cylinder 6 can be sheared and mixed. With the continuous change of the depth, the outline color of the positioning cylinder 471 on the coordinate axis also changes. The shearing depth can be known by the color change, and the shearing position can be known by the change in the position of the coordinate axis, which is convenient for staff to observe and improves work efficiency.
