【摘要】：为使缓释络合盐填料国产化,促进蓄盐沥青路面的发展,通过渗水性试验、溶出性试验和氯离子浓度测定试验对缓释络合盐填料的载体、生产工艺、憎水处理剂以及成分配比进行了设计和选择.确定了具有除冰雪功能和缓释功能的缓释络合盐填料组成为载体C,氯化钠,改性聚硅氧烷A和乙醇,且四者的比例约为4g∶19g∶3mL∶30mL.同时确定了该缓释络合盐填料的生产工艺为:将载体C放在过饱和的氯化钠溶液中,于60℃下恒温搅拌至糊状,然后在135℃下烘干,粉碎后用湿法表面改性工艺对粉体进行憎水处理,最后在135℃下烘干、粉碎.试验结果证明添加了该缓释络合盐填料的沥青路面具有很好的除冰雪能力.
[Abstract]:In order to make the slow release complex salt filler domestic and promote the development of salt storage asphalt pavement, the carrier and production process of slow release complex salt filler were studied by water permeability test, dissolution test and chloride ion concentration determination test.The hydrophobic agent and composition ratio were designed and selected.The slow release complex salt packing with snow and ice removal function and slow release function was determined as carrier C, sodium chloride, modified polysiloxane A and ethanol, and the ratio of the four was about 4 g: 19 g / 3 mL: 30 mL.At the same time, the production process of the slow release complex salt filler was determined as follows: the carrier C was placed in supersaturated sodium chloride solution, stirred to paste at 60 鈩，
