Beschreibung
Zusammenfassung:	The invention relates to the technical field of heat insulation and sound insulation materials, and provides an acoustic glass wool board which comprises the following raw materials in parts by weight: 60-80 parts of glass fibers, 20-30 parts of modified silicon dioxide aerogel and 8-12 parts of an adhesive. The modified silicon dioxide aerogel is obtained by carrying out combined modification on silicon dioxide aerogel by virtue of 4-propyl-naphthalene-1-carboxylic acid and hexadecyl trimethoxy silane. By means of the technical scheme, the problem that in the prior art, glass wool is poor in sound insulation performance is solved. 本发明涉及隔热隔音材料技术领域，提出了一种声学用玻璃棉板，包括以下重量份组分的原料：60~80份玻璃纤维、20~30份改性二氧化硅气凝胶、8~12份粘合剂；所述改性二氧化硅气凝胶为二氧化硅气凝胶经4-丙基-萘-1-羧酸和十六烷基三甲氧基硅烷组合改性得到。通过上述技术方案，解决了现有技术中玻璃棉隔音性能差的问题。
