Modified slow-release salt storage filler and preparation method thereof
The invention relates to the technical field of functional asphalt materials for roads, and discloses a modified slow-release salt storage filler and a preparation method thereof.The modified slow-release salt storage filler is prepared from 50-80 parts by weight of one or more snow melting salts into a saturated solution, 20-40 parts by weight of a carrier material is added for impregnation, and the salt storage filler is obtained after filtering and drying treatment; performing surface treatment on the obtained salt storage filler and 1-10 parts of a surface modifier at the temperature of 50-120 DEG C to obtain a modified slow-release salt storage filler, selecting a mineral or industrial waste material with a porous structure as a carrier material by adopting a mode of combining a composite snow melting salt and a composite porous carrier, and loading the meltable salt into the porous carrier through processing to obtain the modified slow-release salt storage filler. And preparing a powder material. When an asphalt pavement is paved, the salt can be dispersed in asphalt instead of mineral powder, and under the action of vehicle pressure and osmotic pressure, the molten salt can be separated out from the asphalt pavement, so that the effects of melting snow and inhibiting ice are achieved.
本发明涉及路用功能沥青材料技术领域，且公开了改性缓释蓄盐填料及其制备方法，按照重量计将50～80份的一种或几种融雪盐配成饱和合溶液，加入20～40份的载体材料进行浸渍，经过过滤和干燥处理后得到蓄盐填料，将得到的蓄盐填料与1～10份的表面改性剂在50～120℃温度下进行表面处理得到改性缓释蓄盐填料，采用了复合融雪盐与复合多孔载体相结合的方式，选定具有多孔结构的矿物或工业废弃材料作为载体材料，经过加工使可融盐负载到多孔载体中，制备成粉末材料。在铺筑沥青路面时，代替矿粉分散在沥青中，在车辆压力及渗透压作用下，可融盐从沥青路面析出，起到融雪抑冰的作用。
