Problems solved by technology

In the existing technology, the disadvantages of carpets such as heavy weight, high price, and low sound insulation performance have become bottlenecks, restricting the development of carpets in cars, and cannot meet the performance requirements of some cars for carpets
[0003] However, the current production process of automobile sound-proof carpet mainly has the following problems: 1. The raw materials shrink seriously after drying; 2. The production process is complicated, which also greatly increases the production cost; 3. The problem of complicated adjustment of acoustic performance; 4. The preparation process needs to be coated with adhesive, which will inevitably produce harmful substances and is not environmentally friendly; 5. The problem of heavy weight and limited sound insulation effect of the sound insulation pad cannot be solved
However, the carpet is too thick and difficult to dissipate heat due to the multi-layer sound insulation layer and sound absorption layer for sound insulation.

Abstract

The invention provides a high-sound-insulation carpet as well as a preparation method and application thereof. The high-sound-insulation carpet comprises a surface carpet layer, a heavy coating and athermoplastic respun cotton layer which are sequentially stacked. On the basis of reducing the gram weight and the cost of the carpet, the sound absorption and sound insulation performance of the carpet with high sound insulation performance can still be effectively improved.

Description

technical field [0001] The invention belongs to the technical field of automobile interior decoration, and in particular relates to a high-sound-insulating carpet and a preparation method and application thereof. Background technique [0002] With the rapid development of the automobile industry, people's requirements for automobiles are not only beautiful appearance, but also high requirements for comfort, functionality and noise resistance of interior decoration. During the driving process of automobiles, there will be various This kind of noise is transmitted to the compartment, causing noise pollution to the drivers and passengers. Therefore, car carpets are generally installed on the body sheet metal in the car compartment for sound insulation. In the prior art, the disadvantages of carpets such as heavy weight, high price, and low sound insulation performance have become bottlenecks, restricting the development of carpets in cars, and cannot meet the performance requi...
