摘　　要：为解决阻化剂防火技术在应用过程中阻化材料渗透性差、渗流范围难以监测等技术难题,在研究的阻化材料中添加具有渗润作用及荧光示踪作用的罗丹明B。通过接触角测定试验、真三轴煤体渗流试验、热重分析试验,对增润-阻化材料进行了渗润性能和阻化性能的相关测定。研究发现:添加罗丹明B可提高原有阻化液的渗润性能,并且仍具有优良的阻化性能。当罗丹明B添加量在0.1‰时,其渗润、阻化性能最优,接触角相较于未经处理的煤样降低了40.56°,渗透率提高70%左右,干裂温度提升80.13℃,着火温度提高40.2℃。研究结果对渗润范围的快速表征及原位阻化工艺的发展具有积极的促进作用。In order to solve the technical problems such as poor permeability of inhibitor materials and difficult monitoring of seepage range in the process of technical application of inhibitor fire prevention, Rhodamine B with infiltration and fluorescence tracing effects was added to the studied inhibition material. Through contact angle measurement test, true triaxial coal seepage test, and thermogravimetric analysis test, the infiltration and inhibition properties of the infiltration-inhibition materials were measured. Research has found that adding Rhodamine B can improve the infiltration performance of the original inhibitor solution and still has excellent inhibition performance. When the amount of Rhodamine B added is 0.1‰, its infiltration and inhibition performance is optimal. Compared with untreated coal samples, the contact angle is reduced by 40.56°, the permeability is increased by about 70%, the dry cracking temperature is increased by 80.13 ℃, and the ignition temperature is increased by 40.2 ℃. The research results have a positive promoting effect on the rapid characterization of infiltration range and the development of in-situ inhibition technology.
