摘要
研究苯乙烯-丙烯酸丁酯乳液的单体比例及聚灰比(聚合物与水泥的比)对苯乙烯-丙烯酸丁酯乳液改性水泥砂浆性能的影响。研究结果表明:通过改变单体比例而合成的苯-丙乳液所配制的水泥砂浆,其抗弯性能可以得到很大改善,其密实性也大为提高。该改性水泥砂浆可以作为防渗抗裂护面材料。
It studies on the unit ratio of styrene-acrylate emulsion and polymer-cement ratio. Their modification are important to cement mortar performance. The result shows the cement mortar with modified emulsion owns improved bending resistance and compactness. It can be applied as protection material of face with performance of antipenetration and anticrackness.
