Problems solved by technology

As the most commonly used means of transportation, cars have become an indispensable part of people's lives, so it is very necessary to solve the noise generated by the car itself and the noise generated by the outside to improve the comfort of the car occupants. However, the sound insulation effect of the sound insulation cotton used in automobiles is poor at present, and the heat preservation and heat insulation performance of the sound insulation cotton are not good.

Abstract

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.

Description

technical field [0001] The invention relates to the technical field of sound-insulating cotton, in particular to a heat-insulating and sound-insulating cotton for the roof of an automobile compartment. Background technique [0002] Car sound insulation is based on the performance of the vehicle, the corresponding road conditions, etc., the noise generated by the car engine, the vibration resonance sound generated by the tire and the ground, and the friction sound of the components in the compartment due to gaps or aging extrusion force, etc., to improve the quality of the car. ride comfort. As the most commonly used means of transportation, cars have become an indispensable part of people's lives, so it is very necessary to solve the noise generated by the car itself and the noise generated by the outside to improve the comfort of the car occupants. However, the sound insulation effect of the sound insulation cotton used in automobiles is relatively poor at present, and the...
