Sound insulation composite material as well as preparation method and application thereof
The invention relates to a sound insulation composite material and a preparation method and application thereof, and belongs to the technical field of noise reduction materials. The composite material comprises epoxy resin, hollow glass beads, a curing agent, an accelerant, a coupling agent and short carbon fibers. According to the invention, the hollow glass beads are added into the epoxy resin, and the sound insulation effect of the epoxy resin can be further improved by adjusting the content of the hollow glass beads in the composite material; meanwhile, due to the synergistic effect of the chopped carbon fibers and the epoxy resin, the mechanical property of the composite material can be improved while the dispersity and the sound insulation effect of the composite material are not affected, and the composite material has higher practicability. The product is a high-performance acoustic material which is low in price, light in weight and excellent in barrier effect, can be used for low-frequency noise isolation in a living environment, such as a sound insulation and noise reduction plate on a room wall surface, and has wide practical application potential.
本申请涉及一种隔音复合材料及其制备方法和应用，属于降噪材料技术领域。该复合材料包括环氧树脂、空心玻璃微珠、固化剂、促进剂、偶联剂和短切碳纤维。本申请中，在环氧树脂中加入空心玻璃微珠，并通过调节空心玻璃微珠在复合材料中的含量可以进一步的提高环氧树脂的隔音效果；同时，由于短切碳纤维和环氧树脂的协同作用，在不影响复合材料分散性和隔音效果的同时还可以提高复合材料的力学性能，使其具有更高的实用性。该产品是一类价廉、质轻、阻隔效果优异的高性能声学材料，可用于居住环境中的低频噪声隔离，如房间墙面上的隔音降噪板，有广泛的实际应用潜力。
