Abstract

The invention relates to a structure adhesive steel-to-steel tensile shear strength sample preparation method. The structure adhesive steel-to-steel tensile shear strength sample preparation method comprises the following steps: performing surface wetting on steel sheets subjected to sand blasting treatment, wherein a steel wire is placed on one steel sheet, a steel wire is not placed on the othersteel sheet, and the surface is subjected to gluing treatment; placing a horizontal plate well; sequentially placing tables, completely covering the tables with transparent plastic sheet membranes, and fitting the two steel sheets subjected to different treatment according to the size of table cells of the tables; enabling the two steel sheets to be vertical and align with the horizontal plate, clamping the two ends of the overlapped steel sheets by a clamping tool, guaranteeing the positions of the two steel sheets not to be changed, maintaining the test sample under the environment of 23 DEG C for 24 hours, detaching the clamping tool and performing conventional maintenance. By the sample preparation method, the limitation of a specific complex tool can cast off, and accurate sample preparation under the condition of no tools can be realized. The tool is simple and easily available; the limitation that the work sample preparation cannot realize mass continuous sample preparation issolved; and by the method, continuous unlimited sample preparation can be realized.

Description

technical field [0001] The invention relates to the field of measuring adhesive steel-to-steel tensile shear strength, in particular to a sample preparation method for structural adhesive steel-to-steel tensile shear strength. Background technique [0002] GB50728-2011 stipulates the content of the safety appraisal of structural adhesives, among which the steel-to-steel tensile shear strength of the adhesive is an important appraisal index in measuring the bonding ability of the adhesive. GB50728-2011 stipulates that the determination of the tensile shear strength of adhesive steel to steel should be prepared and tested according to the existing national standard GB / T7124. In the existing domestic patented technology, in the tensile and shear sample preparation, it is mentioned that it is necessary to use a correspondingly designed tooling mold to complete the sample preparation more accurately, which is greatly limited by the mold; and a mold There is an upper limit on the...
