粘结和固化参数对建筑结构胶粘结性能的影响

The influence of bond and curing parameters on performance of building structural adhesive

通过丙烯酸酯AB胶和环氧树脂胶的拉伸剪切强度和粘结抗拉强度试验,研究不同胶层厚度、固化温度对试验结果的影响,试验结果表明,胶层厚度变大,结构胶剪切强度和粘结抗拉强度呈下降趋势;适当提高固化温度有利于提高固化程度,但是固化温度过高会造成粘结力下降,研究结果对建筑结构胶拉伸剪切强度和粘结抗拉强度的检测质量起到了保证作用,同时提高了检测结果的准确率。

Through testing bonding shear strength and tensile tensile strength of acrylates AB structural adhesive and epoxy resin structural adhesive,did some research about the influence of different adhesive thickness,curing temperature on the result of the test.The results show that when adhesive thickness increasing,structure adhesive bonding shear strength and tensile strength present a descending trend,an appropriate increase in curing temperature is helpful to improve the curing degree,but curing temperature is too high can cause bonding degree decline.The results play a rule on the quality of detection of building structure adhesive bonding tensile shear strength and tensile strength,and improve the accuracy of detection results.
