摘要
用高沸醇竹子木质素合成了木质素环氧树脂和木质素环氧树脂亲水衍生物。用红外光谱对产物进行了表征,并研究了不同聚/灰比和养护条件对高沸醇竹子木质素环氧树脂及其亲水衍生物改性水泥砂浆的力学性能的影响。结果表明:随着聚/灰比的增加,试样的抗折强度提高,而抗压强度降低,试样的韧性增强,当聚/灰比大于0.12时,抗折强度明显提高;混合养护条件所得试样的综合性能优于水养护条件。
High boiling solvent（HBS） lignin epoxy resin and its hydrophilic derivative were synthesized by HBS lignin from bamboo, the IR spectrum of the products, the effect of different ratio of polymer and curing condition of HBS lignin base epoxy resin to mechanical properties of cement mortar were investigated. The results showed that with the increasing of ratio of polymer to cement, the flexural strength of cement mortar was improved, but its compressive strength was decreased. When the ratio of polymer to cement was more than 0.12, its flexural strength and toughness were apparently improved. The result also showed that the combination of wet and dry curing condition was better than wet curing condition.
