    摘要：考察了5种淀粉醚对水泥基瓷砖胶性能的影响。结果表明，ExcelCon T500淀粉醚能延长瓷砖胶的开放时间；淀粉醚在提高拉伸粘结强度上没有明显优势，但ExcelCon T500淀粉醚在瓷砖胶晾置10 min后效果与纤维素醚接近；ExcelCon A850淀粉醚能显著改善瓷砖胶的抗滑移性。

    Abstract：The effect of 5 kinds of starch ether on the properties of cement-based ceramic tile adhesive was investigated. The results show that the starch ether ExcelCon T500 can prolong the open time of ceramic tile adhesive，starch ether has no obvious advantages in improving the tensile adhesion strength of ceramic tile adhesive，but ExcelCon T500 has almost the same effect on tensile adhesion strength as cellulose ether when the ceramic tile adhesive is kept for 10 min.　The starch ether ExcelCon A850 can significantly improve the anti-slip property of ceramic tile adhesive.
    Key words：starch ether，ceramic tile adhesive，open time，tensile adhesion strength，anti-slip property
