聚合物水泥防水涂料的自修复性能研究

通过试验,考察了不同型号水泥对聚合物水泥防水涂料的自修复性能的影响,结果只有在使用快硬铁铝酸盐水泥情况下聚合物水泥防水涂料才能自我修复。在此基础上,进一步考察了水泥用量、聚醋酸乙烯-乙烯聚合物乳液用量、吸水树脂用量、粉料与液料之比对聚合物水泥防水涂料的自修复性能的影响。试验结果显示:随着水泥及吸水树脂用量的增加,聚合物水泥防水涂料的自修复性能增加;随着聚醋酸乙烯-乙烯聚合物乳液及粉料的增加,聚合物水泥防水涂料的自修复性能先增加后降低。

Study on the Self Repair Property of Polymer Cement Waterproof Coatings

Through the experiments, the influences of different types of cement on the self repair performance of polymer cement waterproof coatings is investigated, getting that only in use of fast hardening ferric aluminate cement, can the self repair performance be obtained. Basing on this, this paper discusses the influence of amount of cement, amount of vinyl acetate - ethylene polymer emulsion, amount of water absorbent resin and the ratio of powder and liquid on the self repair performance. Experiment results show that, with the increase of the amount of cement and water absorbent resin, the self repair performance increases; and with the increase of vinyl acetate - ethylene polymer emulsion and powder, the self repair performance firstly increases and then decreases.
