Anti-freezing agent as well as preparation method and application thereof
The invention discloses an anti-freezing agent and a preparation method and application thereof, and belongs to the technical field of anti-freezing of road surfaces in cold and cold mountainous areas, the anti-freezing agent is prepared from the following raw materials in parts by mass: 460-560 parts of a composite salt saturated solution, 60-80 parts of a corrosion inhibitor, 130-165 parts of a hydrophobic active agent and 230-280 parts of a wrapping material. Composite salt in the anti-freezing agent is screened with the solubility of single-component salt and the phase transformation point of a saturated solution as indexes, and then based on the three-component simplex centroid design thought in mixed material design, the proportion combination with the maximum target value is selected with the ice melting amount as the index; salinization substances are controlled to be uniformly released within the service life of a pavement, the use durability of the pavement is guaranteed, the pavement is used for preparing anti-freezing concrete, the anti-freezing asphalt concrete which is suitable for high and cold areas and has excellent high-temperature performance and water stability is obtained, and the problems of road traffic safety and the like in the high and cold areas can be solved.
本发明公开了一种抗凝冰剂及其制备方法和应用，属于高寒山区路面抗凝冰技术领域，该抗凝冰剂由以下质量份的原料组成：复合盐饱和溶液460～560份、缓蚀剂60～80份、疏水活性剂130～165份、裹附材料230～280份。本发明中抗凝冰剂中复合盐以单组分盐的溶解度以及饱和溶液的相变点为指标进行筛选，其次基于混料设计中三组分单纯型质心设计思想，以融冰量为指标选出目标值最大的配比组合；在路面使用年限内控制盐化物均匀释放，保障其使用耐久性，并将其用于制备抗凝混凝土中，得到适用于高寒地区的具有优异高温性能和水稳定性能的抗凝冰沥青混凝土，可解决高寒地区道路行车安全等问题。
