Description

Technical Field

[0001] The invention relates to the field of interface separation testing between two different substrates in civil engineering, in particular to an interface tensile / shear strength tester for rubber particles and a composite modifier. Background Art

[0002] The pull-off shear tester is a test device used to evaluate the mechanical properties of the material interface, especially for determining the bond strength of composite materials, modified materials, etc. The device evaluates the bond strength of the interface between different materials by simulating the tensile and shear forces that the materials may encounter in actual use. This test is essential to determine the service life, safety and reliability of materials, especially in construction and engineering applications, to ensure that the materials can withstand various loads without failure.

[0003] There are many designs of pull-shear instruments. The basic principle is to use a mechanical arm or electric motor to generate pulling and shearing forces, and to apply forces through a fixture connected to the test sample. These devices usually include mechanical sensors that can accurately measure the force applied to the sample and its response. In this way, data on the behavior of the material when subjected to tension or shearing forces can be obtained, and then the performance indicators of the material can be analyzed. In many industrial and research fields, these data are indispensable for the development of new materials and the improvement of existing materials.

[0004] Although existing pull-off shear instruments have been widely used in many fields, they still have several major limitations. First, the complex design of many devices makes operation and maintenance relatively difficult, which is particularly disadvantageous in a rapid testing environment. Secondly, the continuity and accuracy of data acquisition are often limited by the mechanical properties of the equipment, which is particularly prominent in situations where high-precision testing is required. In addition, the adaptability of existing equipment is poor, and testing of different materials may require equipment with different configurations, which increases costs and operational complexity. Finally, existing technologies often have large errors in characterizing the separation and failure of the interface between two substrates, which is a significant obstacle to the development of new materials that require high-precision interface performance evaluation.

[0045] The present invention also provides a method for using a rubber particle and composite modifier interface tensile / shear strength tester, comprising the following steps:

[0046] Step 1: Prepare two substrates, namely a rubber sheet and a composite modifier, and paste the rubber sheet on the upper surface of a working platform composed of three steel plates 4. The rubber sheet to be pasted needs to be placed in the center of the working platform. After pasting, wait for it to be completely cured. Then, according to the actual construction process of the two substrates, effectively bond the composite modifier on the rubber sheet, that is, complete the combination of the two substrates in the actual state;

[0047] Step 2, when the time for maintenance is reached, the steel ingot 15 and the composite modifier are pasted to the side away from the rubber sheet. After curing, the steel ingot 15 and the lifting ring 11 are sequentially connected to the Z-shaped sensing block 13 by using the screw 12. After connection, the steel wire rope 23 is tightened and then reeled by driving the electric hand chain hoist 20. During this period, the steel wire rope 23 is gradually stressed until the interface between the two substrates is separated and damaged. At this time, the test value can be displayed on the display 19 under the action of the Z-shaped sensing block 13 and the connecting line 14, so that the tension between the two substrate interfaces during the drawing process can be directly read;

[0048] Step three, when the specimen is subjected to a shear test, the preliminary preparation work is the same as the previous steps. The electric hand winch 20 is started and the wire rope 23 is driven to rotate in the opposite direction, so that it is in a relaxed state before the test. At this time, the electric motor 16 is started to rotate the vertical long steel bar 6, the steel pipe 7 and the paper-oriented short steel bar 8 to the paper-oriented plane. At this time, the electric motor 16 is turned off and the value of the display 19 is reset to zero. Then the electric hand winch 20 is driven to reel the wire rope 23 until the interface between the two substrates is separated and damaged. The shear force value between the interfaces of the two substrates during the drawing process can be directly read on the display 19.
