[0026] A process for preparing a highway asphalt additive comprises the following steps: Step 1: preparing raw materials for preparing asphalt additives, the raw materials including styrene, butadiene, isophorone, peroxide, toluene and plasticizer; Step 2: quantitatively add the raw materials in step 1 into the interior of the mixing reaction mechanism 4 by means of the quantitative adding mechanism 5, start the air pressure generating mechanism 2, and stir and shake the materials in the mixing reaction mechanism 4 by means of the power provided by the air pressure generating mechanism 2; Step 3: Cooling the mixed reaction materials in the mixing reaction mechanism 4 to room temperature to obtain the prepared asphalt additive; Step 4: discharge the asphalt additive in the mixing reaction mechanism 4 from the inside of the mixing reaction mechanism 4 and store it.

[0027] Working principle: when preparing the asphalt additive, after the raw materials of the additive are placed inside the mixing reaction mechanism 4, the motor 201 is started, and the output end of the motor 201 rotates, thereby driving the rotating disk 202 to rotate. After the rotating disk 202 rotates, it drives one end of the connecting rod 203 to rotate, forcing the other end of the connecting rod 203 to move back and forth, and then it can drive the slide 204 to move back and forth. After the slide 204 moves back and forth, it can drive the outer sleeve 205 to move back and forth. When the outer sleeve 205 moves toward the direction of the inner rod 207, the one-way valve 1 208 is opened, and the one-way valve 209 is closed to inflate. When the outer sleeve 205 moves in the direction away from the inner rod 207, the one-way valve 1 208 is closed, and the one-way valve 209 is opened to inhale. When inflating, gas is filled into the gas storage box 301 through the air inlet pipe 302. When the air pressure inside the gas storage box 301 is too high, the movable plug 308 is pushed upward under the action of the air pressure. At this time, the movable plug 308 drives the top plate 309 to overcome the tension of the tension spring 310 and move upward. At this time, when the movable plug 308 moves out of the exhaust hollow column 307, the gas storage box 301 can be exhausted to avoid excessive pressure inside the gas storage box 301. When inhaling, The gas inside the pressure stabilizing box 311 is evacuated through the air extraction pipe 312. When the air pressure inside the pressure stabilizing box 311 is too low, the hole disk 315 can be driven downward by the air pressure, and then the air intake column 316 can be driven downward. When the air intake groove 317 moves to the inside of the base tube 313, the outside air will enter the inside of the base tube 313 through the air intake groove 317, and enter the inside of the pressure stabilizing box 311 through the holes on the hole disk 315, so as to prevent the air pressure inside the pressure stabilizing box 311 from being too low. When the reactor 401 moves back and forth, it can drive the toothed flywheel 411 to move. At this time, with the cooperation of the toothed plate 412, the toothed flywheel 411 can be driven to rotate. The toothed flywheel 411 can drive the rotating shaft 402 to rotate. The rotating shaft 402 drives the mounting plate 403 to rotate, thereby driving the mounting cylinder 404, the connecting column 407 and the scraping stirring frame 408 to rotate, and then the materials inside the reactor 401 can be stirred to accelerate the reaction. When discharging, the hydraulic cylinder 8 can be started. After the output end of the hydraulic cylinder 8 is extended, it can drive the reactor 401 to rotate, so that the discharge pipe 7 rotates to the bottom. At this time, the solenoid valve 409 is opened. At this time, the gas in the air storage box 301 will enter the interior of the reactor 401 through the ventilation hose 410, accelerating the discharge of the reactor 401 and making the material discharge cleaner. When adding materials, open automatic valve 1 502, and the air inside the metering cylinder 501 is extracted through the vacuum hose 503. At this time, open automatic valve 2 504. Since the gas inside the metering cylinder 501 is extracted, suction is generated inside the metering cylinder 501, and then the raw materials can be drawn in through the feed pipe 505. When the material reaches the required amount, automatic valve 2 504 is automatically closed. At the same time, close automatic valve 1 502 and open electric valve 507, and the material inside the metering cylinder 501 will enter the interior of the reactor 401, thereby completing the addition of raw materials.
