摘要
为比选六种常用防水粘结层材料的力学性能,分别对试件进行斜剪试验、拉拔试验、疲劳试验,从而确定了最佳防水粘结层材料;在此基础上,研究洒布量与抗剪强度、拉拔强度之间的关系,并采用单因素方差分析方法对试验结果进行检验,从而确定了最佳洒布量。试验结果表明:MMA抗剪切性能、抗拉拔性能以及疲劳性能均为最优,MMA最佳洒布量为160~170 g/m^2。
In order to study the mechanical properties of six kinds of commonly used waterproof adhesive layers materials, indoors tests including oblique shear test, drawing test, fatigue test on the specimens have been carried out to determine the best waterproof adhesive layer material, and the best dosage of materials could be determined through study on relations between dosage and shear & pull strength. The results have shown that the shear strength, pull-out resistance and fatigue properties of the MMA are the best, and the optimal dosage of the MMA is 160 -170 g/m2.
