Description

Stripping-resistant agent and preparation method and application thereof
Technical Field
The invention belongs to the petroleum industry and the basic material chemistry field, in particular to an asphalt stripping-resistant agent and a preparation method thereof, which are particularly suitable for an airport asphalt runway.
Background
The highest temperature of air flow sprayed by a modern jet plane engine can reach 850-900 ℃, the air flow speed can reach 180m/s, the air flow is diffused to an airport runway surface in an oval shape, the surface temperature of the runway surface is rapidly increased, and asphalt runway surface damage is caused. The measured data show that when the summer air temperature is 40 ℃, the highest temperature of the asphalt pavement reaches 140 ℃ under the influence of the aircraft height Wen Weiliu. Therefore, in order to avoid the damage of the runway surface, the end parts of the civil airport runway are provided with the anti-blowing flats, and enough preparation time is provided for the airplane in the take-off stage. However, the stage of aircraft running still inevitably causes the temperature of the runway surface to rise suddenly, and the temperature stress is generated to cause the damage of the runway surface, thereby affecting the durability of the runway. The main damage form is that under the blowing of high-temperature air flow sprayed by a jet aircraft, coarse aggregate on the surface of an asphalt runway is extremely easy to peel off, foreign invaders (FOD) are formed, and the FOD can cause serious flight accidents once being sucked into an aircraft engine. Therefore, the high-temperature stripping resistance of the coarse aggregate of the asphalt concrete runway is improved, and the method is an important research direction for improving the civil aviation operation safety.
At present, polymer modified asphalt with better high-temperature performance is widely adopted for paving airport runways worldwide, so that the problems of pavement deformation and threshing under the conditions of aircraft wake baking and high shear stress are solved, but the effect is not ideal, and after a period of use, pavement bulge cracking and aggregate stripping frequently occur, so that huge flight potential safety hazards and high maintenance cost are increased. At present, aiming at the aggregate stripping problem of expressways or common roads, mainly aiming at the water damage resistance, a method for adding an anti-stripping agent into asphalt or asphalt mixture is proposed, but the temperature, the tail gas flow, the air flow speed and the like of automobile tail gas on the roads are greatly different from those of the tail gas of jet aircrafts. Therefore, the aim of adding the stripping-resistant agent on the highway is mainly considered to be water damage resistance and prevent aggregate stripping when asphalt concrete is affected by water; the main consideration on the runway is the purging effect of the jet aircraft with high Wen Weiliu, high temperature (850-900 ℃), large air flow and high air flow speed (180 m/s). There is no anti-stripping agent developed specifically for the problem of asphalt concrete aggregate stripping of airport runways due to the influence of jet aircraft altitude Wen Weiliu.

During the experiment, the asphalt to be tested is melted and then placed in a metal tray, and the asphalt is spread flatly to form a film with the thickness of 3mm plus or minus 0.3 mm. The tray with the asphalt film is arranged at the bottom in the cylinder body and is firmly fixed. The bottom of the cylinder body has a heating function, so that the temperature of asphalt in the tray is maintained at 60+/-20 ℃ (the temperature of Wen Shilu table in summer simulation). The engine is started, so that high-temperature tail gas of the engine enters from one end of the straight cylinder, the other end of the straight cylinder is discharged, the high-temperature tail gas is blown over the asphalt membrane, the blowing is continued for 30 minutes, and the blowing is stopped for 10 minutes, so that the process is continuously repeated for a plurality of times. One experimental period was 240 hours from the initial start of blowing. And then taking out the asphalt, analyzing each performance, and comparing the performance with the performance before the simulation experiment. The method simulates the condition of asphalt on an airport runway (especially in a take-off section) when the asphalt is purged by high-temperature tail gas of an airplane for a long time, and examines the change of asphalt properties, especially the change of stripping resistance.
In the invention, the asphalt adhesion strength is obtained by testing with a drawing tester. The instrument and the test method are as follows:
instrument and equipment: drawing tester with model PosiTest AT-A, tester parameters: a draw rate of 150psi/s; test range 0-2000psi; the test method is as follows:

The liquid asphalt spreads evenly under the action of spindle gravity, and after cooling, the spindle and the white steel plate are bonded, and the thickness of the asphalt film is about 0.1mm. The white steel plate cooled to room temperature and the spindle were put in an environmental box (temperature: 20 ℃ C.; relative humidity: 50 Rh%) and kept AT constant temperature for 1 hour, and then taken out, and the adhesion was measured using a Positest AT-A tester. The drawing strength value at the time of separating the spindle from the metal plate was recorded. The value is used for representing the stripping resistance of asphalt, and the greater the value is, the better the stripping resistance is.
