Embodiment

[0029] As a specific embodiment of the present invention, aluminum flakes and glass flakes are used as substrates. Aluminum flake 1 is a cuboid with a size of 100mm*25mm*2mm; glass flake 5 is a cuboid with a size of 100mm*25mm*5mm; aluminum flake, glass The sheet is cleaned with cleaning agent first, and after drying, the surface of the end of the aluminum sheet is treated with primer 2, and the treatment size is 100mm*25mm*12.5mm; the surface of both ends of the glass sheet is treated with primer 2, and the treatment size is 100mm* 25mm*12.5mm. The aluminum sheet 1 is placed on the first operation part of the sample preparation operation platform, and the end treated by the primer 2 is placed close to the second operation part upwards, and a 4 mm thick one-component moisture-curing polyurethane elastic adhesive 3 is coated on it, and the The glass piece 5 is placed on the second operating part of the sample preparation operation platform, and the surface treated by the primer...

Abstract

The invention provides an elastic adhesive fatigue property test structure and a manufacturing method thereof. The elastic adhesive fatigue property test structure comprises an operating platform, two aluminum sheets and a glass sheet, wherein the operating platform comprises first operating parts and a second operating part, the two operating parts are arranged on two sides of the second operating part respectively, the horizontal plane where the upper surface of the second operating part is located is higher than the horizontal plane where the upper surfaces of the first operating parts are located, the two aluminum sheets are arranged on the first operating parts respectively, end parts of the aluminum sheets are connected with the side surface of the second operating part, the upper surface, close to one end of the second operating part, of each aluminum sheet is coated with one layer of ground coat, elastic adhesives are arranged on the ground coats, the glass sheet is arranged on the second operating part, the lower surfaces of the two end parts of the glass sheets are coated with one layer of ground coat respectively, and the ground coats are connected with the elastic adhesives. The sample preparation process is simple, the labor intensity and the difficulty of the sample preparation process are reduced, the sample preparation time is shortened, and the sample preparation efficiency is improved.

Description

technical field [0001] The invention relates to an elastic adhesive fatigue performance testing structure and a manufacturing method thereof, belonging to the technical field of elastic adhesive performance testing. Background technique [0002] With the development of bonding technology, more and more elastic adhesives are used in the production of rail vehicles, and they play a vital role. However, the theoretical basis for the vibration fatigue of elastic adhesives with large elastic modulus is still in the domestic market. There is no specific theoretical and experimental proof for the service life of elastic adhesives, and there are limitations to the aging resistance of elastic adhesives and the application of elastic adhesives. In order to better understand the aging resistance of elastic adhesives and improve the basic theory of elastic adhesive application, it is necessary to simulate the actual operating conditions of vehicles to verify the technical data of elasti...
