Flame-retardant warm-mixed modified asphalt as well as preparation method and application thereof
The invention discloses flame-retardant warm-mixed modified asphalt as well as a preparation method and application thereof, and the flame-retardant warm-mixed modified asphalt comprises the following components in parts by mass: 100 parts of modified asphalt; 3-8 parts of a warm mixing agent; and 4-10 parts of a flame retardant. The flame retardant is prepared from decabromodiphenyl ethane, antimony trioxide and aluminum hydroxide according to the mass ratio of (3-7):(0.5-2):(0.5-2); and the warm mixing agent comprises artificial zeolite. According to the flame-retardant warm-mixing modified asphalt disclosed by the invention, the warm-mixing performance of the asphalt is improved through the artificial zeolite, and the artificial zeolite is matched with the flame retardant, so that the oxygen index of the asphalt can be synergistically improved, the ignition time of the asphalt can be prolonged, and the combustion heat release rate and CO release rate of the asphalt can be reduced.
本发明公开了一种阻燃温拌改性沥青及其制备方法和应用，按质量份，包括以下组分：改性沥青100份；温拌剂3‑8份；阻燃剂4‑10份；其中，所述阻燃剂包括质量比为(3‑7)：(0.5‑2)：(0.5‑2)的十溴二苯乙烷、三氧化二锑和氢氧化铝；所述温拌剂包括人造沸石。本发明的阻燃温拌改性沥青，通过人造沸石在提高沥青的温拌性能的同时，与本发明的阻燃剂搭配，可以协同提高沥青的氧指数，延长沥青点燃时间，降低沥青燃烧热释放速率和CO释放率。
