Description

technical field [0001] The invention relates to the field of damping functional materials, in particular to a flame-retardant wide temperature range high damping composite material and a preparation method thereof. Background technique [0002] Vehicles, subways, high-speed rails and other means of transportation are closely related to our lives. The vibration and noise generated during their operation not only cause a significant decrease in ride comfort, but also seriously affect the normal life of surrounding residents. Spraying / paving viscoelastic damping materials inside the vehicle chassis and body profiles is an effective means of reducing vibration and noise. [0003] The commonly used viscoelastic damping material is a polymer material with special viscoelasticity, which mainly utilizes the relaxation effect of the molecular chain segment of the polymer material in a certain temperature range. Under the action of vibration load, the molecular chains of polymer visc...
