Composite sound insulation material, composite sound insulation board and preparation method of composite sound insulation board
The invention discloses a composite sound insulation material, which is prepared from the following raw materials in parts by mass: 50 to 60 parts of ethylene-vinyl acetate copolymer, 10 to 20 parts of polystyrene, 5 to 8 parts of glass fiber cotton, 8 to 10 parts of aluminum hydroxide, 6 to 8 parts of 2-butyl phenol, 13 to 18 parts of zinc stearate and 10 to 12 parts of xylene. According to the sound insulation material, the ethylene-vinyl acetate copolymer and the polystyrene are adopted, so that the use amount of the glass fiber cotton is reduced, the sound insulation effect is improved, and meanwhile, the weight of a sound insulation plate made of the sound insulation material is reduced.
本发明公开了一种复合隔音材料，所述复合隔音材料由以下质量份数的原料组成：50‑60份乙烯‑醋酸乙烯共聚物，10‑20份聚苯乙烯，5‑8份玻璃纤维棉，8‑10份氢氧化铝,6‑8份2‑丁基苯酚，13‑18份硬脂酸锌、10‑12份二甲苯。本发明的隔音材料通过采用乙烯‑醋酸乙烯酯共聚物和聚苯乙烯，降低了玻璃纤维棉的使用量，不仅提高了隔音效果，同时，降低了使用该隔音材料制成的隔音板的重量。
