Abstract

The invention discloses a multi-layer structure sound-insulating carpet and a preparation method thereof. The sound-insulating carpet separates the inner wall of an automobile compartment from the space of the automobile compartment; the sound-insulating carpet is arranged on the inner wall of the automobile compartment at prescribed intervals; the sound-insulating carpet It has a sound insulation part; the sound insulation part is arranged between the sound insulation carpet and the inner wall of the car compartment; the sound insulation part has a transmission favorable part and a transmission unfavorable part, and the transmission favorable part is a favorable part for the transmission of outside noise, And the transmission favorable part surrounds the periphery of the transmission unfavorable part, and the transmission favorable part is more favorable for the transmission than the unfavorable part; the noise transmission is suppressed from the transmission mode by the sound insulation member, thereby suppressing the transmission of the noise to the vehicle compartment. ; The sound insulation carpet installed in the way of ensuring the normal use of materials, through the combination of dispersion and extension, weakens the energy of the sound in the transmission, enhances the acoustic impedance, and has higher sound insulation.

Description

technical field [0001] The invention relates to the technical field of carpets, in particular to a multi-layer structure soundproof carpet and a preparation method thereof. Background technique [0002] The noise generated by the moving car and the outside of the car will be transmitted into the car compartment, including but not limited to: noise from friction between the road and tires, noise from the engine and transmission, and noise from the chassis of the car, etc. ; [0003] These noises will be introduced into the car compartment through the car, thus affecting the ride experience and quietness of the car. Usually, manufacturers use carpets to sound insulation. Carpets are equipped with sound insulation materials. improve the sound insulation of the cabin by means of materials (increasing the amount of materials and using more expensive and rarer materials); [0004] Schematic illustration: ordinary soundproof carpets have less than 5 layers of structure, and incre...
