Description

A kind of flame retardant soundproof cotton

technical field

The utility model relates to the field of sound-insulating cotton, in particular to a flame-retardant sound-insulating cotton.

Background technique

As we all know, the noise generated by the car when it is idling, accelerating or driving on different road surfaces will be amplified and transmitted into the car after the chassis and car body resonate or resonate, making the driver and passengers feel uncomfortable. The sound insulation cotton can convert the noise vibration energy into the kinetic energy of the fine denier fiber inside the sound insulation cotton and then conduct it into heat energy and disappear, so as to achieve the function of sound absorption and noise reduction. Therefore, the sound insulation cotton quilt is widely used in the automobile manufacturing industry, but the existing sound insulation cotton is Without flame retardant performance, the sound insulation cotton will burn in case of fire, causing major disasters.

Utility model content

The technical problem mainly solved by the utility model is to provide a flame-retardant sound-insulating cotton, which can solve the defect that the existing sound-insulating cotton does not have flame-retardant performance.

In order to solve the above technical problems, a technical solution adopted by the utility model is to provide a flame-retardant sound-insulating cotton, comprising: a polyester foam layer, a flame-retardant fiber fireproof layer attached to the upper and lower surfaces of the polyester foam layer, the The polyester foam layer is evenly distributed with up and down sound-absorbing holes, the diameter of the sound-absorbing holes is 2-8mm, the sound-absorbing holes are filled with sound-absorbing cotton, and the flame-retardant fiber fireproof layer is a flame-retardant glass fiber cloth layer. A flame retardant glass adhesive layer is coated between the flame retardant glass fiber cloth layer and the polyester foam layer.

In a preferred embodiment of the utility model, the thickness of the polyester foam layer is 1-5 cm.

In a preferred embodiment of the utility model, the porosity of the sound-absorbing hole is 40-50%.

In a preferred embodiment of the utility model, the thickness of the flame-retardant glass fiber cloth layer is 0.5-2.5 mm.

The beneficial effects of the utility model are: the utility model adopts a multi-layer composite structure, and a flame-retardant glass fiber cloth layer is attached to the upper and lower surfaces of the polyester foam layer, which can effectively enhance the strength and flame-retardant performance of the sound-insulating cotton. Sound-absorbing holes are evenly distributed on the foam layer, and sound-absorbing cotton is filled in the sound-absorbing holes, which can effectively improve its sound insulation performance.

Description of drawings

Fig. 1 is the structural representation of a preferred embodiment of the utility model flame-retardant soundproof cotton;

The marks of the components in the accompanying drawings are as follows: 1. Polyester foam layer, 2. Flame-retardant fiber fireproof layer/flame-retardant glass fiber cloth layer, 3. Flame-retardant glass glue layer, 11. Sound-absorbing holes, 4. Sound-absorbing cotton.

detailed description

The preferred embodiments of the utility model will be described in detail below in conjunction with the accompanying drawings, so that the advantages and characteristics of the utility model can be more easily understood by those skilled in the art, so that the protection scope of the utility model can be defined more clearly .

Please refer to Fig. 1, the utility model embodiment comprises:

A flame-retardant sound-insulating cotton, comprising: a polyester foam layer 1, a flame-retardant fiber fireproof layer 2 attached to the upper and lower surfaces of the polyester foam layer 1, and the polyester foam layer 1 is evenly distributed with sound-absorbing holes penetrating up and down 11. The diameter of the sound-absorbing hole 11 is 2-8mm, the sound-absorbing hole 11 is filled with sound-absorbing cotton 4, the flame-retardant fiber fireproof layer 2 is a flame-retardant glass fiber cloth layer, and the flame-retardant glass fiber cloth layer 2 and the polyester foam layer 1 are coated with a flame-retardant glass adhesive layer 3.

Preferably, the polyester foam layer 1 has a thickness of 1-5 cm.

The porosity of the sound-absorbing holes 11 is 40-50%, and the sound-absorbing holes 11 are densely and evenly distributed on the polyester foam layer 1, which can effectively absorb noise.

The thickness of the flame retardant glass fiber cloth layer 2 is 0.5-2.5 mm, which can effectively enhance the strength of the sound insulation cotton and make it have flame retardant performance.

The utility model discloses a flame-retardant and sound-insulating cotton, which adopts a multi-layer composite structure, and a flame-retardant glass fiber cloth layer is attached to the upper and lower surfaces of the polyester foam layer, which can effectively enhance the strength and flame-retardant performance of the sound-insulating cotton, and at the same time, it is made of polyester foam. The ester foam layer is evenly distributed with sound-absorbing holes, and the sound-absorbing holes are filled with sound-absorbing cotton, which can effectively improve its sound insulation performance.

The above is only an embodiment of the utility model, and does not limit the patent scope of the utility model. Any equivalent structure or equivalent process conversion made by using the utility model specification and accompanying drawings, or directly or indirectly used in other Related technical fields are all included in the patent protection scope of the present utility model in the same way.
