Description

TECHNICAL FIELD

[0001] The present application belongs to the field of special asphalt, and particularly relates to an environmentally-friendly sand-containing fog seal layer for insect repelling and a preparation method thereof. BACKGROUND

[0002] In recent years, the natural environment has been significantly improved, and the number of insects has gradually increased. However, the activity range of these insects covers some highways, which poses a threat to driving safety. During high-speed driving, a large number of insect corpses will adhere to the windshield of the vehicle, seriously blocking the driver's view. In addition, many highways have been in service for a long time, and there are disease problems that need to be solved. At the same time, some sections of highways and parks are often under strong sunlight, causing the road surface temperature to rise and generating toxic gases such as volatile organic compounds and sulfides. The release of such gases not only harms the ecological environment, but also has a negative impact on human health.

[0003] CN113881341B discloses a high-performance fog seal material and its application, which introduces water-based epoxy resin, water-based polyurethane and water-based acrylic resin into the fog seal material to improve the high-low temperature performance of the fog seal material. However, the material provided by this method can only repair early-stage diseases of asphalt pavement and cannot inhibit the release of asphalt fumes from asphalt pavement under the action of high temperature, nor can it avoid the impact of insects on driving safety.

[0004] Therefore, there is an urgent need to develop a road surface material that can effectively maintain the highway pavement, inhibit the release of toxic gases, and prevent insect pests, so as to achieve the dual goals of driving safety and environmental protection. SUMMARY
