Abstract

The invention discloses an asphalt aging inhibitor applied to northeast coastal areas. The common action of propylene glycol, nano-scale spinel powder, raw vermiculite powder and flame-retardant polyamide 66 composite fibers achieves excellent flame retardation and smoke suppression effects in the combustion process, so the flammability of asphalt is effectively reduced, and the use safety and theconstruction safety of an asphalt pavement are improved; the addition of propylene glycol can improve the low temperature resistance of the aging inhibitor, and an added iron-sodium diethylenetriaminepentaacetate complex can resist the corrosion of chloride ions and other inorganic salts in seawater to the asphalt pavement; and the aging inhibitor is mainly prepared by grinding natural minerals,is free from phosphorus and halogen, has no adverse effects on the environment, and has a remarkable environmental protection benefit.

Description

technical field [0001] The invention relates to the technical field of modified asphalt, in particular to an asphalt anti-aging agent used in northeast coastal areas and a preparation method thereof. Background technique [0002] In recent years, my country's high-grade highways are gradually extending from plains and slightly hilly areas to mountainous and heavy hilly areas, so the construction of tunnels has achieved rapid development. Asphalt pavement material is widely used in tunnel pavement because of its advantages of comfortable driving, low noise and high traffic safety. However, while the tunnel traffic is constantly improving, the risk of tunnel fire accidents is also increasing. When accidents such as collision of faulty vehicles and spontaneous combustion of vehicle-loaded goods occur in the tunnel, it is very easy to cause tunnel fire accidents. Once a fire breaks out in the tunnel, the asphalt will participate in the combustion and produce a large amount of ...
