一种乳化沥青改性剂、制备方法及其在制备改性乳化沥青中的应用
摘要：
本发明公开了一种乳化沥青改性剂、制备方法及其在制备改性乳化沥青中的应用，属于道路建筑材料技术领域。本发明的技术方案要点为：一种乳化沥青改性剂，是由以下重量份的原料制备而成的：多聚磷酸3‑6份、苯乙烯‑丁二烯嵌段共聚物12‑24份、非离子沥青乳化剂10‑15份和去离子水30‑40份。本发明还具体公开了该乳化沥青改性剂的制备方法及其在制备改性乳化沥青中的应用。本发明的乳化沥青改性剂生产工艺中不使用溶剂，不仅避免了环境污染，而且避免了溶剂残留对乳化沥青蒸发物性能的负面影响，并具有简单便捷的技术优势。
摘要（英）：

The invention discloses an emulsified asphalt modifier, a preparation method and application of the preparation method to preparation of the modified emulsified asphalt, and belongs to the technical field of road building materials. The technical scheme of the invention is characterized in that the emulsified asphalt modifier is prepared from the following raw materials in parts by weight: 3 to 6 parts of polyphosphoric acid, 12 to 24 parts of styrene-butadiene block copolymer, 10 to 15 parts of non-ionic asphalt emulsifier, and 30 to 40 parts of deionized water. The invention further specifically discloses a preparation method of the emulsified asphalt modifier and application of the preparation method to preparation of the modified emulsified asphalt. In a production process of the emulsified asphalt modifier, no solvent is used, so that environmental pollution is avoided, and negative influences of solvent residue on the performance of evaporated emulsified asphalt are avoided; the preparation method is simple and convenient.
