Description

technical field

[0001] The invention relates to the technical field of polymer composite materials, in particular to a high-toughness sound-insulating composite material and a preparation method thereof. Background technique

[0002] At present, noise has become a major environmental pollution, and people pay more and more attention to the problem of acoustic environment. Selecting appropriate materials for sound absorption and sound insulation is one of the most commonly used and basic technical measures in noise control engineering. The difference between material sound absorption and material sound insulation is that material sound absorption focuses on the size of the reflected sound energy on one side of the sound source, and the goal is to reduce the reflected sound energy; material sound insulation focuses on the size of the transmitted sound energy on the other side of the incident sound source, and the goal is The transmitted sound energy is smaller.
