Description

TECHNICAL FIELD

[0001] The present application belongs to the field of special asphalt, and particularly relates to a smoke-suppressing bird-repelling sand-containing fog seal and a preparation method thereof. BACKGROUND

[0002] In recent years, the natural environment in China has been significantly improved, and the number of birds has gradually increased. However, their activities cover some airports, which has caused certain influence on the process of taking off and landing of airplanes, and may lead to unexpected bird collision accidents, causing troubles in the operation of airports. In addition, at the present stage, many airport pavements in China have a long service life, and diseases occur in the airport runways. At the same time, the airport runways are often under strong sunlight, and the pavement temperature is relatively high, which leads to the generation of volatile organic compounds, sulfides and other toxic gases from heated asphalt. The release of such gases not only causes harm to the ecological environment, but also has a negative impact on human health. In order to solve the above problems, it is necessary to develop a pavement material which can effectively maintain the airport runway, suppress the release of irritating gases from asphalt and repel birds.

[0003] CN115677267A discloses an anti-falling agent, anti-falling bird-repelling asphalt mixture and a preparation method thereof. The method improves the road performance of the airport pavement and gives it a bird-repelling effect by adding an additive with bird-repelling and anti-falling effects in the process of preparing the asphalt mixture. However, the additive used in the method is mainly sulfur, which has a heavy irritating smell and makes airport personnel feel uncomfortable. In addition, the use of the material requires re-paving the airport pavement, which is difficult to apply on a large scale.

[0004] Therefore, it is necessary to develop a pavement material which can effectively maintain the highway pavement, suppress the release of toxic gases and prevent bird damage, so as to realize the dual goals of driving safety and environmental protection. SUMMARY

[0109] Compared with the prior art, the present application has the following advantages:

[0110] (1) After the smoke-reducing and bird-repelling sand-containing fog seal of the present application is applied to the road surface, the smoke-reducing and bird-repelling microcapsules in the system release an odor that can stimulate the sense of smell of birds, so that the birds feel uncomfortable and leave the surrounding of the road surface.

[0111] (2) Compared with the traditional bird-repelling asphalt material, which has the defects of heavy irritating odor and short bird-repelling time, the smoke-reducing and bird-repelling sand-containing fog seal of the present application can slowly release the bird-repelling component with a certain fragrance for a long time, thus having good bird-repelling effect and avoiding discomfort to the human body.

[0112] (3) The smoke-reducing and bird-repelling sand-containing fog seal of the present application has extremely short curing time under sunlight irradiation and excellent embedding effect on the road surface, thus effectively prolonging the service life of the road surface.

[0113] (4) The smoke-reducing and bird-repelling microcapsules contained in the smoke-reducing and bird-repelling sand-containing fog seal of the present application have a composite shell material comprising silicon dioxide / nano tourmaline, which has three effects, the first of which is that, during preparation, the nano tourmaline acts as a template agent for microcapsule synthesis, maintaining the stability of the core material mixed liquid droplets; the second of which is that, during modification of the metal ions in the microcapsule composite shell material, the negative ion field released by the nano tourmaline under high temperature conditions adsorbs a large amount of metal ions to the surface of the microcapsule, effectively improving the loading amount of the metal ions in the microcapsule shell material and further improving the smoke-reducing ability; the third of which is that, during the service of the asphalt road surface, the nano tourmaline contained in the shell material of the smoke-reducing and bird-repelling microcapsule releases a negative ion field, further attracting the compounds released by the asphalt road surface under the action of high temperature to the surrounding of the smoke-reducing and bird-repelling microcapsule, which not only improves the difficulty of volatilization of these compounds, but also makes the metal ions on the surface of the microcapsule react with more of the above-mentioned compounds, thereby effectively reducing the impact of the irritating gas released during the service of the asphalt road surface on the human body.

[0114] (5) The smoke-reducing bird-repelling microcapsule contained in the smoke-reducing bird-repelling sand-containing fog seal of the present application has a large number of metal ions on its surface modified by chelation, and these metal ions have empty orbits. After the volatile gas is released from the asphalt pavement under the action of high temperature, the metal ions can directly accept the unshared electrons of some relatively active sulfur-containing and nitrogen-containing pollutants with irritating odor in the asphalt and form coordination bonds, thereby stably fixing the above-mentioned compounds on the surface of the microcapsule and effectively preventing them from volatilizing into the air, further reducing the harm of the irritating gas released from the asphalt pavement to the environment and human body.

[0207]

[0208]

[0209] The bird activity frequency in the test area is summarized, and the obtained data is shown in Table 2.

[0212]

[0213] The main gases released by the asphalt pavement under the influence of high temperature are volatile organic compounds and sulfides. To verify the smoke-reducing ability of the smoke-reducing bird-repelling sand-containing fog seal material on the asphalt material, the samples prepared in Examples 1-7 and Comparative Examples 1-4 are spread on the surface of the asphalt mixture test block, the size of the asphalt mixture test block is 10cm*10cm*3cm, and the samples are further moved into a closed container with a gas inlet, and stored at a temperature of 80℃ for 2 days. After storage, the gas in the closed container is sucked, and the VOCs and H2S contents in the gas are tested using a VOC detector and a smoke detector, and the obtained data is shown in Table 3.

[0214] From the test data, the content of volatile organic compounds and hydrogen sulfide in the smoke generated by the test block spread with the smoke-reducing bird-repelling sand-containing fog seal material is greatly reduced. Reducing the smoke-reducing bird-repelling microcapsule can reduce the smoke-reducing effect of the smoke-reducing bird-repelling sand-containing fog seal material, and the smoke-reducing bird-repelling sand-containing fog seal material without adding the smoke-reducing bird-repelling microcapsule has little smoke-reducing effect.
