Damping materials are materials that convert solid mechanical vibration energy into thermal energy and dissipate it, mainly used for vibration and noise control. The damping performance of a material can be measured based on its ability to dissipate kinetic energy, and the standard for evaluating damping is the damping coefficient. Missiles, launch vehicles, and aircraft during flight can cause severe broadband random vibration and noise environments due to engine operation and aerodynamic noise. They can also excite numerous resonance peaks in structures and electronic control instrument systems, causing fatigue failure and dynamic instability of structures, reducing the accuracy of electronic control instruments, and even causing malfunctions. Statistics show that about one-third of rocket ground and flight test failures are related to vibration, and the poor damping performance of structural materials is an important reason for such failures. In order to improve the damping performance of the structure, structural materials and damping materials can be combined into composite materials, that is, the structural materials bear stress, and the damping materials produce damping effect to achieve the purpose of controlling vibration and reducing noise. It is one of the best materials for shock absorption and noise reduction. The pollution and harm caused by noise are receiving increasing attention from people. This also puts forward higher requirements for the vibration reduction and noise reduction performance of damping materials. According to the paper by PDA International Director Wang Baozhu and others, damping materials represented by water-based damping coatings and constrained damping coatings have achieved breakthrough applications in the following aspects. In the automotive industry, the use of damping materials enhances the airtightness of cars, reduces vibration, reduces noise, and improves the comfort of cars; In construction engineering, the application of damping materials can not only reduce the harm caused by wind vibration, but also offset the natural cycle of the building from the seismic cycle, thereby minimizing these natural hazards and ensuring the safety of people's lives and property; In the mechanical industry, the use of damping materials can minimize mechanical noise and vibration, enabling smooth and quiet operation, improving work efficiency, and extending the service life of equipment
