The invention discloses a composite sound-insulation flame-retardant cotton felt for automotive interiors and a processing technology of the composite sound-insulation flame-retardant cotton felt, andrelates to the technical field of sound-insulation flame-retardant materials. A plurality of cellucotton felt layers, polyethylene films and graphene layers are fixedly arranged between the pair of metal skins, the cellucotton felt layers and the graphene layers are alternately arranged, the middles of the cellucotton felt layers and the graphene layers are fixedly bonded through the polyethylenefilms, and a plurality of through holes are formed in an inner cavity of each cellucotton felt layer at equal intervals. Activated carbon fiber rods are fixedly arranged in the through holes, so thatthe sound insulation board not only has excellent sound insulation performance, but also has antibacterial and moth-resistant performance. By reducing the glue spraying process, a large amount of labor cost and production cost are saved, and the production efficiency is improved; heat can be rapidly diffused, the phenomenon of local overheating is effectively avoided, and a good flame-retardant effect is achieved.
本发明公开了汽车内饰用复合型隔音阻燃棉毡及其加工工艺,它涉及隔音阻燃材料技术领域;所述一对金属蒙皮之间固定设置有数层纤维棉毡层、聚乙烯膜和石墨烯层,所述纤维棉毡层和石墨烯层保持相间排列交替设置,且纤维棉毡层和石墨烯层的中间通过聚乙烯膜保持固定粘结,所述纤维棉毡层的内腔等距设置有数个通孔,所述通孔内固定设置有活性炭纤维棒,它不仅具有优异的隔音性能,同时还具有抑菌、抗蛀虫性能;并通过减少喷胶工艺,节省了大量人力成本和生产成本,提高了生产效率;其可以迅速将热量扩散,有效避免局部过热的现象,具有很好的阻燃效果。
