摘要:
针对水性环氧乳化沥青应用于道路养护存在提前破乳和分层等相容性问题,调研了国内外水性环氧乳化沥青相容性的研究进展,深入探讨了影响其相容性的关键因素,归纳对比了其相容性评价方法,并从原材料、添加剂和工艺角度总结了其相容性改善措施。研究结果表明:水性环氧乳化沥青的相容属于工艺性相容,环氧树脂与沥青的溶解度参数存在差异是导致其破乳和分层的根源,乳化剂界面膜强度、液体黏度和共混体系粒径差等均显著影响水性环氧乳化沥青的相容性; 现有相容性评价方法可分为客观评价和主观评价,不同方法评价角度不同,原理不一样,且评价标准不统一,主观评价方法最易受到人为及外界因素的影响; 在制备水性环氧乳化沥青时,可以从选择溶解度参数相近的原材料、提高乳液分散均匀程度及添加含活性基团的外加剂等方面改善其的相容性; 在制备和施工过程中,应注意温度、时间等因素的影响,以获得分布均匀、性质稳定的水性环氧乳化沥青; 未来研究应聚焦于构建多相乳液体系模型和发展直观化与量化评价方法,进一步探究水性环氧乳化沥青相容性与混合料性能的内在关联,着力提升水性环氧乳化沥青相容性,并将相容性改善思想贯穿于整个生产和应用过程。
Abstract:
In view of the compatibility issues of waterborne epoxy emulsified asphalt(WEEA)applied in roadmaintenance, such as premature demulsification and phase separation, the research progress on the compatibility of WEEA both domestically and internationally was investigated, key factors affecting itscompatibility were thoroughly analyzed, compatibility evaluation methods were systematically categorized and comparatively analyzed, and compatibility improvement measures were summarized from the perspectives ofraw materials, additives, and processing techniques. The research results demonstrate that the compatibility of WEEA is processing-dependent. The difference in solubility parameters between epoxy resin andasphalt is identified as the root cause of demulsification and phase separation. The interfacial filmstrength of emulsifier, liquid viscosity, and particle size difference in the blendedsystem significantly affect the compatibility of WEEA. Existingcompatibility evaluation methods can be classified into objective assessments and subjective observations.Different methods are characterized by distinct evaluation perspectives and principles, and lack unified criteria. Subjective evaluation methods are particularly prone to being affected by human and external factors. When preparing the WEEA in practice, its compatibility can be improved by selecting raw materials with closely similar solubility parameters, enhancing emulsion dispersion homogeneity, and incorporating additives containingactive functional groups. During preparation and construction processes, attention should be paid to the factors such astemperature and duration to achieve uniformity and stability of WEEA.Future research should focus on developing the construction of multiphase emulsion systemmodels and the establishment of visualized and quantifiable evaluation methods, further exploration of the intrinsicrelationship between the compatibility of WEEA and mixture performance,investigation of strategies to enhance compatibility, and the integration of compatibility optimization principlesthroughout the entire production and application processes.5 tabs, 11 figs, 62 refs.
