The invention discloses a resin material with low density and high sound insulation as well as a preparation method and application thereof. The resin material comprises the following components in parts by weight: 40-60 parts of copolymer resin, 35-50 parts of inorganic nano filler, 5-20 parts of hollow glass beads, 1-5 parts of a lubricant, 0.1-5 parts of a compatilizer and 0.1-5 parts of a surface modifier. By compounding the hollow glass beads and the inorganic nanofiller, the sound insulation performance of the resin material is greatly improved under a small addition amount, and the hollow structure of the hollow glass beads is not damaged under the protection of the lubricant, so that the resin material keeps low density.
本发明公开了一种具有低密度、高隔音的树脂材料及其制备方法和应用。本发明的树脂材料,包括如下重量份的组分:共聚物树脂40~60份,无机纳米填料35~50份,空心玻璃微珠5~20份,润滑剂1~5份,相容剂0.1~5份,表面改性剂0.1~5份。通过空心玻璃微珠与无机纳米填料复配,在较小的添加量下大幅提高了树脂材料的隔音性能,且空心玻璃微珠在润滑剂的保护下,空心结构不被破坏,使得树脂材料保持低密度。
