AI Technical Summary
The flame retardant and sound insulation cotton has aging over time during use, and the sound insulation effect is limited, so it cannot effectively reduce noise penetration.
A high-density flame-retardant sound-insulating cotton is designed. By setting a fused cotton column and flame-retardant ball in the rubber frame, and setting a sound-absorbing cotton cylinder and sound-absorbing hole in the sound-insulating cotton layer, a multi-layer structure is formed to achieve rapid flame retardant and efficient sound-absorbing.
When the flame retardant material ages, the fused cotton column burns and releases the substance in the flame retardant ball, forming a fast flame retardant barrier. At the same time, the sound-absorbing cotton cylinder reduces noise through multiple reflections and sound-absorbing grooves, improving the flame retardant and sound insulation effect.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of flame-retardant sound insulation cotton, and specifically, to a high-density flame-retardant sound insulation cotton. Background Art
[0002] Flame-retardant sound insulation cotton is a material with flame-retardant and sound insulation functions. Its main component is polyester fiber, and a flame retardant is added through special treatment to achieve the purpose of flame retardancy. This material not only has good sound insulation effect, can effectively reduce the transmission of noise, and provide a quiet environment, but also has flame-retardant properties, that is, it is not easy to burn, automatically extinguishes after leaving the fire source, and will not reignite, thus improving the fire safety of the material. In addition, this material also has excellent properties such as heat preservation, flame retardancy, environmental protection, light weight, easy processing, stability, and impact resistance, and is particularly suitable for places such as offices that require good sound insulation and fire prevention.
[0003] However, when the existing flame-retardant sound insulation cotton is in use, the flame-retardant effect is only achieved through materials with flame-retardant properties. However, as the material is used and time goes by, the flame-retardant performance of the flame-retardant material will age, affecting the subsequent flame-retardant effect. Moreover, the sound insulation performance of the existing flame-retardant sound insulation cotton is also achieved through sound-absorbing cotton. Simply using sound-absorbing cotton for sound insulation treatment has a poor effect, can only simply isolate large noises, and cannot prevent the penetration of noise to the greatest extent. Therefore, the sound insulation effect has limitations. Summary of the Utility Model

[0013] (III) Beneficial effects
[0014] Compared with the prior art, the present utility model provides a high-density flame-retardant sound-absorbing cotton, which has the following beneficial effects:
[0015] 1. For this high-density flame-retardant sound-absorbing cotton, by arranging the flame-retardant ball and the fuse cotton column, and setting them inside the rubber frame and between the flame-retardant and sound-absorbing materials to form a flame-retardant layer. When the flame-retardant performance of the flame-retardant material deteriorates due to aging, high temperature and flame will burn off the fuse cotton column. At this time, the flame-retardant gas or flame-retardant liquid inside the flame-retardant ball will be released, and then a flame-retardant barrier will be formed, thereby achieving rapid flame retardancy, improving the flame-retardant effect of the flame-retardant sound-absorbing cotton, and ensuring safety in a timely manner when the flame-retardant material ages and fails.

Then, a sound-absorbing groove is drilled through the inside of the sound-absorbing cotton cylinder and sound-absorbing holes are opened on the surface. When noise enters the inside of the sound-insulating cotton layer, sound waves will be absorbed and reflected when hitting the sound-absorbing cotton cylinder. Subsequently, through the hexagonal sound-absorbing cotton cylinder, the sound is reflected at multiple angles. The sound waves enter the sound-absorbing groove through the sound-absorbing holes and are continuously reflected in the sound-absorbing groove, thereby reducing the sound wave energy and achieving an efficient sound-absorbing and noise-reducing effect, enhancing the sound-insulating effect of the flame-retardant sound-insulating cotton.

[0022] The following further describes in detail the embodiments of the present invention in conjunction with the drawings and examples. The following examples are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.
[0023] Example 1
[0024] Please refer to Figures 1-4, the present utility model: a high-density flame-retardant sound insulation cotton, comprising a flame-retardant sound insulation cotton layer 1. On both opposite sides of the flame-retardant sound insulation cotton layer 1, there are isolation cotton layers 2. On the edge position of one side of the isolation cotton layer 2 away from the flame-retardant sound insulation cotton layer 1, there is a rubber frame 3. On the other side of the upper rubber frame 3, there is a flame-retardant glue layer 4. On the other side of the flame-retardant glue layer 4, there is an outer layer 5. On the side of the other rubber frame 3 away from the isolation cotton layer 2, there is a mesh yarn flame-retardant glue layer 6. On the side of the mesh yarn flame-retardant glue layer 6 away from the rubber frame 3, there is a release paper 7. Inside the flame-retardant sound insulation cotton layer 1, there is a sound-absorbing cotton cylinder 8. The sound-absorbing cotton cylinder 8 is provided with sound-absorbing grooves 9 running through it, and the surface of the sound-absorbing cotton cylinder 8 is provided with sound-absorbing holes 10 running through it. The sound-absorbing holes 10 communicate with each other. After the sound enters the sound-absorbing holes 10, through reflection inside the sound-absorbing grooves 9, the sound energy is continuously weakened, and then the noise is absorbed, thereby achieving a more efficient sound insulation and noise reduction effect. Inside the rubber frame 3, there is a fixed connection with a fuse cotton column 11, and the fuse cotton column 11 is fixedly connected with a flame-retardant ball 12. The flame-retardant ball 12 serves as a structure for assisting in flame retardancy. When the outer side of the flame-retardant sound insulation cotton is damaged and burns due to flames and high temperatures, at this time, the flame-retardant ball 12 can rupture and release flame-retardant substances for rapid flame retardancy and fire extinguishing, minimizing the combustion damage as much as possible and quickly achieving the flame retardant effect of the flame-retardant sound insulation cotton.
[0025] The flame-retardant ball 12 is made of rubber material, and inside the flame-retardant ball 12, there is filled with one or more of flame-retardant gas and flame-retardant liquid. The outer layer 5 is one or more of aluminum foil paper and fiberglass cloth. The thickness of the outer layer 5 is 0.13 mm, the thickness of the flame-retardant glue layer 4 is 40 μm, and the thickness of the mesh yarn flame-retardant glue layer 6 is 55 μm. Through the mesh yarn flame-retardant glue layer 6 and the flame-retardant glue layer 4, replacing the original flame-retardant cotton, the glue has better flame-retardant characteristics and a longer service life of the glue. Therefore, in cooperation with the internal flame-retardant ball 12, it can better play the flame-retardant role of the flame-retardant sound insulation cotton.
[0026] Embodiment Two
[0027] Refer to Figure 1 - Figure 3 , on the basis of Embodiment One, there is a further improvement:
[0028] On the inner wall of the sound-absorbing groove 9, there is a fixed connection with a rib 13. The two arc surfaces of the rib 13 are arranged. The cross-section of the end of the sound-absorbing cotton cylinder 8 is hexagonal. There are two rows of the sound-absorbing cotton cylinders 8, and they are arranged alternately up and down. Between the upper and lower two rows of sound-absorbing cotton cylinders 8, there is a reinforcing cotton 14. The sound-absorbing cotton cylinder 8 is a hexagonal cylinder, having good impact resistance. And between the sound-absorbing cotton cylinders 8, there is also a reinforcing cotton 14, providing a supporting force between the sound-absorbing cotton cylinders 8. Therefore, the internal structure of the flame-retardant sound insulation cotton layer 1 has good impact resistance, enabling the flame-retardant sound insulation cotton to have better high-density and high-strength characteristics.
[0029] The working principle of the present utility model is as follows: When in use and a fire breaks out, the flame retardant glue layers 4 on both sides of the flame retardant and sound insulation cotton and the grid yarn flame retardant glue layer 6 can timely carry out flame retardant isolation. However, when the flame retardant glue layer 4 and the grid yarn flame retardant glue layer 6 have a decline or failure in the flame retardant effect due to various reasons such as aging or damage, at this time, the flame burns to the position of the rubber frame 3. At this time, the high temperature and flame will burn off the fuse cotton column 11. At this time, the flame retardant ball 12 falls off and melts at high temperature, and the flame retardant inside the flame retardant ball 12 is released for flame retardant, so that the flame retardant and sound insulation cotton can carry out flame retardant better and more stably. During daily use, the flame retardant and sound insulation cotton reduces noise for the externally transmitted noise. When the sound wave enters the flame retardant and sound insulation cotton layer 1, at this time, the sound is blocked and reflected by the sound absorption cotton cylinder 8. Through multiple reflections, part of the sound is blocked and absorbed by the sound absorption cotton cylinder 8 and the reinforcing cotton 14, and the other part of the sound is reflected and enters the sound absorption groove 9 through the sound absorption holes 10. Subsequently, the sound is repeatedly reflected and absorbed in the sound absorption groove 9, thereby reducing noise. And the sound wave is blocked by the convex strip 13 in the sound absorption groove 9, and thus presents the effect of being reflected in different directions, greatly increasing the time for the sound to be absorbed and filtered, and thus improving the sound insulation effect of the flame retardant and sound insulation cotton.
[0030] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present utility model, rather than to limit the protection scope of the present utility model. Although the present utility model has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present utility model can be modified or equivalently replaced without departing from the essence and scope of the technical solutions of the present utility model.
