摘　　要：提出通过掺加丁—苯共聚物乳液来改善磷酸镁水泥的柔性。强度结果表明,聚合物的加入,在保证抗压强度的同时,能够明显提高抗折强度,此外还起到缓凝的作用。SEM结果表明,聚合物的加入可以阻止大裂缝的产生。In this paper,the improvement of the flexibility of magnesium phosphate cement by adding butadiene-styrene copolymer emulsion is presented.The strength results show that the addition of polymer can not only ensure the compressive strength but also improve the flexbility and retarder.SEM results show that the addition of polymer can prevent the formation of cracks.

关 键 词：磷酸镁水泥 丁—苯共聚物乳液 抗折强度
