[0002] Composite silicone sealants are widely used in fields such as construction, automotive engineering, and aerospace engineering. In their applications, fatigue resistance is crucial because these materials usually need to maintain their performance and integrity under long-term dynamic loading and deformation. Therefore, it is necessary to design a composite silicone sealant fatigue resistance testing equipment;

The silicone sealant performance testing device provided by the present invention utilizes a heating component to heat the tank body of the thermal expansion gas storage tank. The heating of the thermal expansion gas storage tank can cause the nitrogen in the tank to expand after the thermal expansion gas storage tank is heated. As the nitrogen in the thermal expansion gas storage tank expands, the expanded nitrogen in the thermal expansion gas storage tank enters the gas cylinder through the detection hole, thereby pushing the piston in the gas cylinder and the sliding rod on the piston to slide along the outside of the gas cylinder. At this time, the spring begins to compress, and the indicator needle on the sliding rod can well indicate the amount of internal expansion of the thermal expansion gas storage tank, thereby facilitating the staff to monitor the silicone sealant products and ensure that the silicone sealant products sold are all qualified products;
