Flame-retardant asphalt mixture and preparation method thereof
The invention discloses a flame-retardant asphalt mixture and a preparation method thereof, and belongs to the technical field of tunnel construction, the flame-retardant asphalt mixture comprises the following raw materials: matrix asphalt, mineral powder, gravel and a flame retardant; the flame retardant is obtained by emulsion polymerization, washing and drying of an aqueous solution containing 8-12 parts of hydroxide, 2-3 parts of zinc borate and 3-5 parts of calcium bicarbonate and a solution containing 8-12 parts of poly (N-isopropylamide), 4-8 parts of polypropylene, 3-7 parts of paraffin and 10-15 parts of polydimethylsiloxane; the preparation method of the flame-retardant asphalt mixture comprises the following steps: mixing and stirring the broken stones and the mineral powder to obtain a mixture; and heating the matrix asphalt to 150-165 DEG C, stirring, then adding the mixture and other raw materials, and carrying out wet mixing to obtain the flame-retardant asphalt mixture. The flame retardant has the characteristics that the defects caused by overlarge addition amount of hydroxide flame retardants are overcome, and meanwhile, the flame retardant property is excellent.
本发明公开了一种阻燃沥青混合料及其制备方法，属于隧道施工技术领域，所述阻燃沥青混合料原料包括基质沥青、矿粉、碎石和阻燃剂；所述阻燃剂由含8‑12份氢氧化合物和2‑3份硼酸锌以及3‑5份碳酸氢钙的水溶液以及含有8‑12份聚N‑异丙基酰胺、4‑8份聚丙烯和3‑7份石蜡以及10‑15份聚二甲基硅氧烷的溶液通过乳液聚合后洗涤干燥得到；阻燃沥青混合料制备方法包括以下步骤：将碎石和矿粉混合搅拌，得到混合物；将基质沥青加热到150‑165℃，并进行搅拌，然后加入混合物和其余原料，进行湿拌，得到阻燃沥青混合料。本申请具有解决氢氧化合物阻燃剂添加量过大引发的缺陷，同时具有优异的阻燃性能的特点。
