Zusammenfassung:The invention discloses a nano asphalt flame-retardant smoke inhibition modifying agent and preparation thereof. The modifying agent comprises the following components: 25 to 40 parts of nano laminated magnesium hydroxide, 5 to 15 parts of nano cerium oxide, 5 to 20 parts of melamine, 35 to 50 parts of polyolefin, 1 to 10 parts of coupling agent, and 5 to 10 parts of compatibilizer. The invention discloses a method for preparing the asphalt flame-retardant modifying agent. The asphalt flame-retardant modifying agent has the characteristics of good dispersity, easy adding, safety and the like; and because of the nano laminated magnesium hydroxide serving as a flame retardant and the nano cerium oxide serving as a smoke inhibitor, the asphalt flame-retardant modifying agent is environment-friendly, and meanwhile can improve the flame-retardant smoke inhibition performance of the system, reduce the using amount of the flame retardant, improve the mechanical property of the asphalt, achieve multiple effects such
