[0004] Chinese patent (CN103819915A) discloses a graphene oxide modified asphalt and its preparation method. Graphene oxide can be used as a modifier to improve the basic performance of asphalt, but there is a lack of related research on the performance of modified asphalt waterproof membranes for roads and bridges , In addition, the price of graphene is high, and the amount of too much directly leads to an increase in the cost of road and bridge construction; Chinese patent (CN102190957A) proposes to add magnesium-aluminum-based layered double hydroxide to asphalt, and use magnesium-aluminum-based layered double hydroxide The physical shielding effect on ultraviolet rays can improve the anti-ultraviolet aging ability of elastomer-modified asphalt, but in the process of use, asphalt is not only aged by ultraviolet light, but also thermal-oxidative aging by heat and oxygen. The effect of magnesium-aluminum-based layered double hydroxide on improving the heat-oxidative aging resistance of asphalt is not obvious; adding antioxidants to asphalt can improve the heat-oxidative aging resistance of asphalt to a certain extent, but due to the antioxidant It is a low-molecular-weight organic compound, which is easily volatilized by heat when it is mixed with hot asphalt under high temperature conditions, and its own aging resistance to thermal oxygen aging will also be reduced, resulting in the anti-aging effect of antioxidants on asphalt not being effective for a long time

Background technique [0002] Asphalt has long been used as a building waterproof material, but asphalt is easy to flow at high temperature and cracks at low temperature, which is difficult to meet the application of roof waterproofing projects. The properties of asphalt-based waterproof materials mainly depend on the asphalt coating material used, polymer modified asphalt Due to its excellent high-temperature heat resistance and low-temperature crack resistance, coating materials have become one of the important asphalt coating materials. Road and bridge waterproofing projects are exposed to direct sunlight, and high-temperature environments have a strong effect on asphalt and polymer modifiers. , it is e...
