摘　　要：利用正交试验研究了可再分散胶粉、木质纤维、膨胀剂及胶砂比对瓷砖粘结剂的粘结强度、压折比及干燥收缩率的影响,结合综合平衡法及功效系数法分析了各因素及水平对粘结剂性能的影响规律;评价了粉煤灰、铝酸盐水泥及憎水胶粉对粘结剂的泛霜抑制效果.研究结果表明:可再分散胶粉与胶砂比显著影响粘结剂的粘结强度、压折比及干燥收缩率;憎水胶粉能显著抑制粘结剂的泛霜程度.The adhesive strength, compressive/flexural strength ratio and drying shrinkage of tile adhesive determined by redispersible polymer powder, wood fiber, expand agent and binder/sand ratio were conducted by means of the orthogonal test. The effect of given factors on the performance of tile adhesive were evaluated with comprehensive equilibrium method and efficiency coefficient method. Meanwhile, the effect of fly ash, aluminate cement and hydrophobic polymer powder on the efflorescence resistance was studied too. The results show that redispersible polymer powder and binder/sand ratio exert marvelous effect on adhesive strength, compressive/flexural strength ratio and drying shrinkage of tile adhesive, and hydrophobic polymer powder can reduce the efflorescence of tile adhesive effectively.
