摘　　要：制备了煤岩体注浆加固用聚氨酯/环氧树脂双组分注浆材料,对A、B双组分浆液的动态流变性能进行了研究。结果表明,浆液的非牛顿指数随着温度升高而减小。在30℃时,当A料中聚醚多元醇KGF400D与KGF450质量比为1∶1,B料PAPI质量分数为90%,TCPP质量分数为10%时,双组分浆液均接近牛顿流体,浆液的灌注性能稳定;在A料组分为纯的KGF400D时,双组分浆液黏度对温度敏感性相同。In order to reinforce broken coal and rock, two-component polyurethane/epoxy grouting material was made. Rheological property of the two-component A and B were studied. The results indicated that the non-Newtonian index showed a downward trend with the increase of the temperature. When the mass ratio of polyether polyol KGF400D and KGF450 was 1 ： 1 in A component at 30℃ and the mass ratio of PAPI and TCPP was 9 ： 1 in B component,the material was close to Newtonian fluid. Syringeability of the materials was stable. The susceptibility of viscosity to temperature of the two-component was almost same when the component in A was pure KGF400D.
