摘要
通过斯莫尔Small.P.A分子引力常数的分子构造推定方法,运用溶解度参数以及高分子相对质量分布等理论,研究分析了不同溶剂和稀释剂对环氧树脂灌浆材料黏度的影响,并结合Dual-Arrhenius方程探讨了灌浆材料在不同温度下的化学流变特征。结果表明,溶剂与树脂溶解度越相似,其树脂体系的黏度越小;单环氧基的活性稀释剂501对灌浆材料稀释的效果与溶剂丙酮相当,是环氧树脂灌浆材料的优良稀释剂;建立了环氧树脂灌浆材料的流变模型,该模型与实际测试结果相关性良好,可以用于确定不同温度下灌浆材料的可操作时间。
With the theories of solubility and relative molecular mass distribution,the influence of different solvent and thinner on the viscosity of epoxy resin grouting material was studied and analyzed by method of molecule construction, in which Small·P·A gravitational constant was used. Its chemical rheological behaviors under different temperatures were also discussed based on the Dual-Arrhenius equation. The results indicate that the more semblance of the solubility between solvent and resin, the less on the viscosity of resin：the dilute effect of 501 with one epoxy group is similar with acetone,so it＇s an excellent thinner in epoxy resin. A rheological model was constructed and met the factual experimental number perfectly,so it can fix on the operational time of the grouting material under different temperatures.
