摘要
采用水玻璃—聚氨酯相结合的方式,对聚氨酯注浆料进行改性。将廉价的水玻璃材料转化为有机的硅氧链引入聚氨酯,可以降低成本。实验结果表明:随着水玻璃的引入,聚氨酯注浆料的耐水性、抗水溶蚀性、力学性能得到进一步改善,并对水玻璃改性聚氨酯注浆料的机理进行了分析。
Polyurethane grouting material is modified by using combining method of sodium silicate and polyurethane. Costs are reduced by introduction of organic silicon-oxygen chain changed from cheap sodium silicate material into polyurethane. Experiments show that the performance of water resistance, corrosion resistance against water and mechanical properties of modified polyurethane grouting material is further improved. The modification mechanism is also analyzed.
