Problems solved by technology

However, at present, phenolic resin cotton is generally used as the material of automobile sound insulation pads and some interior parts. Due to the synthesis mechanism of phenolic resin cotton and its special properties, it contains harmful substances and pungent odors, and it has been placed in the interior of the car for a long time. It will bring some pollution to the environment inside the car, and at the same time, it will also cause certain harm to the human body.

Abstract

The invention discloses a heat-insulated, sound-proof and shock-absorbent fiber mat and a preparation method. The heat-insulated, sound-proof and shock-absorbent fiber mat comprises a damping sound-proof felt, a PVC layer, a heat dispersion layer, a honeycomb layer, a sound-absorbing cotton layer, filling powder and shock-absorbent nets. The damping sound-proof felt is arranged on the outer surface of the heat-insulated, sound-proof and shock-absorbent fiber mat, the PVC layer is attached to the inner surface of the damping sound-proof felt, the heat dispersion layer is attached to the inner surface of the PVC layer, the honeycomb layer is attached to the inner surface of the heat dispersion layer, the sound-absorbing cotton layer, is arranged in the middle of the honeycomb layer, honeycomb holes in the honeycomb layer are filled with the filling powder, and the shock-absorbent nets are arranged in the heat dispersion layer and the honeycomb layer respectively. In the heat-insulated, sound-proof and shock-absorbent fiber mat and the preparation method, multiple layers of sound-proof layers are arranged, and in each layer, a suitable raw material is selected and a scientific raw material ratio is adopted. The prepared heat-insulated, sound-proof and shock-absorbent fiber mat can reduce noise and absorb shock, unnecessary noise hazards are reduced, safe driving can be ensured, the structure is simple, and the fiber mat is convenient to use.

Description

technical field [0001] The invention relates to the technical field of fiber felt production, in particular to a heat-insulating, sound-insulating, and shock-absorbing fiber felt and a preparation method thereof. Background technique [0002] With the rapid development of the world economy and the continuous improvement of people's living standards, the automobile industry has developed rapidly. People's requirements for automobiles are not only beautiful appearance, comfort and functionality of interior decoration, but also new requirements for environmental protection performance and noise resistance performance of vehicle interior decoration. However, at present, phenolic resin cotton is generally used as the material of automobile sound insulation pads and some interior parts. Due to the synthesis mechanism of phenolic resin cotton and its special properties, it contains harmful substances and pungent odors, and it has been placed in the interior of the car for a long ti...
