Description

Technical Field

[0001] This invention belongs to the field of petroleum industry and basic materials chemistry, specifically relating to an anti-shedding and anti-aging agent and its preparation method, which is particularly suitable for airport asphalt runways. Background Technology

[0002] Modern jet aircraft emit high-temperature exhaust fumes (850℃-900℃) and high-speed airflow (180m / s). Under the influence of these high-temperature exhaust fumes, the light components in airport asphalt runways are prone to volatilization, easily causing thermal aging of the asphalt. As the oil content decreases, the asphalt becomes heavier, gradually hardening and becoming brittle, easily causing the surface coarse aggregate to loosen and detach. If the detached aggregate is ingested into the aircraft engine, it can cause serious flight accidents. Therefore, improving the high-temperature stability and coarse aggregate detachment resistance of asphalt concrete materials is an important research direction for improving civil aviation operational safety. It is necessary to develop a high-temperature resistant, detachment-resistant asphalt material suitable for use in airport runways, establish a dedicated evaluation method for high-temperature resistance and detachment resistance of airport asphalt, and form a complete set of systematic and scientific supporting technologies to meet the future demand for high-quality asphalt materials for airport runways. However, currently, there is no anti-detachment and anti-aging agent specifically developed for the problems of asphalt aging and concrete aggregate detachment caused by the high-temperature exhaust fumes of jet aircraft on airport runways.

[0030] The present invention has the following beneficial effects:

[0031] 1. The anti-detachment and anti-aging agent of this invention can not only significantly improve the anti-detachment performance of asphalt, but also improve the heat aging resistance of asphalt.

The resulting product has high viscosity and flexibility, as well as good polarity, so that the anti-detachment and anti-aging agent can enable asphalt to have better high-temperature detachment resistance and heat aging resistance under high temperature environment. Detailed Implementation

[0034] The technical solution of the present invention will be described in detail below with reference to the embodiments, but the present invention is not limited to the following embodiments. In the present invention, wt% is a mass fraction.

[0035] This invention presents a method for simulating high-temperature aircraft exhaust blast: An aircraft engine (e.g., a replaced engine) is connected to a cylindrical, heated, high-temperature resistant material at its tail. During the experiment, the asphalt to be tested is melted and placed in a metal tray, spread out as a thin film with a thickness of 3mm ± 0.3mm. The tray containing the asphalt film is placed at the bottom of the cylindrical body and secured firmly. The bottom of the cylindrical body has a heating function to maintain the asphalt temperature in the tray at 60℃ ± 20℃ (simulating road surface temperature during summer). The engine is turned on, allowing high-temperature exhaust gas to enter from one end of the cylindrical body and exit from the other, blowing over the asphalt film continuously for 30 minutes, followed by a 10-minute pause, repeating this process multiple times. One experimental cycle is 240 hours, starting from the initial blowing. The asphalt is then removed, and its properties are analyzed and compared with those before the simulation experiment. This simulates the condition of asphalt on airport runways (especially the takeoff section) under long-term exposure to high-temperature aircraft exhaust blast, examining changes in asphalt properties, particularly its resistance to shedding.

[0036] In this invention, the asphalt adhesion strength is obtained by testing with a pull-out tester. The instrument and testing method are as follows:

[0037] Instruments and equipment: PosiTest AT-A pull-out tester; tester parameters: pull-out rate 150 psi / s; test range 0-2000 psi; test method as follows:

[0038] Weigh 0.03g of asphalt onto the test surface of the spindle. Place the asphalt-coated spindle on a hot plate. After the asphalt melts, spread it evenly within 10 seconds. Simultaneously, quickly transfer a preheated stainless steel plate to a horizontal workbench. Place the asphalt-coated spindle onto the stainless steel plate and allow it to cool to room temperature (approximately 1 hour). The liquid asphalt spreads evenly under the weight of the spindle and, after cooling, bonds to the spindle and stainless steel plate, forming an asphalt film thickness of approximately 0.1mm. Place the cooled stainless steel plate and spindle in an environmental chamber (temperature: 20℃; relative humidity: 50%RH) for 1 hour, then remove them and test the adhesion using a PosiTest AT-A tester. Record the pull-out strength value when the spindle separates from the metal plate. This value characterizes the asphalt's resistance to detachment; a higher value indicates better resistance.

[0067] As shown in Table 2, adding the anti-detachment and anti-aging agent of this invention to asphalt significantly improves the adhesion strength and anti-detachment performance of asphalt. After one cycle of aircraft high-temperature wake simulation experiments, the adhesion strength of asphalt with the added anti-detachment and anti-aging agent not only did not decrease but actually increased, indicating that the anti-detachment and anti-aging agent of this invention not only improves the anti-detachment performance of asphalt but also has strong anti-heat aging properties, making it highly adaptable to the high-temperature wake environment of aircraft. In contrast, the adhesion strength of asphalt without the added anti-detachment agent decreased significantly after the simulation experiment. Adding a commercially available anti-detachment agent, compared to the anti-detachment and anti-aging agent of this invention, resulted in a smaller improvement in adhesion strength; although the adhesion strength did not decrease after the simulation experiment, it also showed little significant improvement.
