摘要

针对煤矿深部巷道围岩加固对注浆材料的高性能需求，系统综述了矿用聚氨酯注浆材料的研究现状。首先，通过剖析聚氨酯注浆材料的组成及反应机理，明确了硬段结构与软段骨架对材料强度与韧性的贡献。其次，结合行业标准JC/T 2041-2020，确立了包括浆液渗透性、固结性能及环境安全性的多维度性能评价体系，并对比了亲水型（WPU）与疏水型（OPU）材料的技术指标差异。重点探讨了近年来国内外在降低反应热、提升阻燃等级、增强力学性能以及开发环境友好型聚氨酯材料等方面的改性策略，为高性能煤矿用聚氨酯注浆材料的研发提供参考。

Abstract：

To meet the high-performance requirements of grouting materials for reinforcing surrounding rocks in deep coal mine roadways, the current research status of mine-use polyurethane (PU) grouting materials were systematically reviewed. Firstly, the respective contributions of hard-segment structures and soft-segment skeletons to material strength and toughness were elucidated by analyzing the composition and in-situ formation mechanism of PU grouting materials. Secondly, a multi-dimensional performance evaluation system was established based on the industry standard JC/T 2041-2020, encompassing slurry permeability, solidified body performance, and environmental safety. The technical specification differences between hydrophilic (WPU) and hydrophobic (OPU) materials were also compared. Furthermore, the recent domestic and international modification strategies were highlighted focused on reducing reaction heat, enhancing flame retardancy, improving mechanical properties, and developing eco-friendly PU materials. It was provided that the theoretical foundation and practical reference for the development of high-performance polyurethane grouting materials in coal mining.
