The invention relates to the technical field of sound insulation cotton, and discloses heat and sound insulation cotton for a roof in an automobile compartment, the heat and sound insulation cotton comprises a heat preservation layer, a heat insulation layer is arranged at the bottom of the heat preservation layer, a sound absorption layer is arranged at the bottom of the heat insulation layer, and a sound insulation layer is arranged at the bottom of the sound absorption layer. The sound insulation cotton is designed into four layers, the first heat preservation layer enables the sound insulation cotton to have a heat preservation function, the automobile roof is not affected by the external environment, the second heat insulation layer enables the sound insulation cotton to have a heat insulation function, when the temperature of the roof is too high, the heat cannot be transmitted into an automobile, and the comfort of passengers of the automobile is not affected, and the third sound absorption layer converts sound energy into heat energy and reduces the noise influence, the fourth sound insulation layer enables the sound insulation cotton to have the sound insulation function, the sound insulation layer can block sound transmission, noise cannot be generated in the automobile, the functionality of the sound insulation cotton is increased through the multi-layer arrangement, and meanwhile the practicability of the sound insulation cotton is greatly improved.
本发明涉及隔音棉技术领域,且公开了一种汽车车厢内车顶用隔热隔音棉,包括保温层,所述保温层的底部设置有隔热层,所述隔热层的底部设置有吸音层,所述吸音层的底部设置有隔音层,本发明通过将隔音棉设计为四层,第一层保温层使隔音棉具有保温的功能,使汽车车顶不受外部环境影响,第二层隔热层使隔音棉具有隔热的功能,当车顶温度过高时,不会传递到车子内部,影响汽车乘坐人员的舒适性,第三层吸音层,将声能转化为热能,降低噪音影响,第四层隔音层使隔音棉有隔音功能,隔音层可以阻断声音的传播,使车内不会产生噪音,通过多层设置,增加了隔音棉的功能性,同时也大大提高了隔音棉的实用性。
