摘　　要：采用保水剂、粘结剂改性,可配制施工性、粘结性、耐候性良好的特细砂瓷砖粘结砂浆。它的抗流挂性好,滑移量小于2 mm,有较充分的凉置时间,凉置20 min的粘结强度大于1.0 MPa,可满足瓷砖粘贴薄层施工的要求。采用聚丙烯纤维复合改性,可配制抗裂性较好的柔性瓷砖粘结砂浆。介绍这种新型粘结砂浆的配制原理、方法和性能。By modification with water-retentive agents and organic bonding admixtures, one dry-mixed superfine sand mortar used as ceramic tile bonding was prepared with good workability, adhesive capacity and climate resistance. The test results indicate that this mortar has excellent anti-sagging characteristics, with slippage of less than 2mm, sufficient open time and bonding strength over 1 MPa after being open for 20 minutes. These traits provide the needed qualities for thin construction of ceramic tile bonding. By adding polypropylene fiber, a flexible mortar was prepared with superior crack resistance for use as a ceramic tile bonding agent. The preparation mechanism, method and performance are introduced in detail.
