| 摘 要： | 利用醋酸乙烯酯／甲基丙烯酰氧乙基三甲基氯化铵（VAC／DMC）阳离子型无皂乳液对水泥砂浆进行了改性研究，并与普通VAC均聚物乳液进行了比较。研究表明，！与普通水泥砂浆相比，VAC/DMC节离子型无皂乳液改性砂浆（聚灰比为0．1时）的抗折强度较普通砂浆够提高77％，其改性效果明显好于普通VAC乳液，表明用阳离子无皂乳液改性水泥性能能够取得良好效果。探讨VAC／DMC对水泥砂浆改性的原因。 |

| Abstract: | Cement mortars were modified with the soap_free cationic emulsion copolymer of vinylacetic acid (VAC) and methacyloyloxyethyl trimethylammonium chloride (DMC). The properties of the modified mortars were compared with those modified with polyvinyl acetate (PVAC). The results indicate that in comparison with plain cement mortar, the bending strength of the mortars modified with soap_free emulsion of VAC/DMC[ m (p)/ m (c)=0.1] increases by 77%, better than with PVAC. The mechanism of the modification is discussed. |
