Description

Technical Field

[0001] This utility model relates to the field of foam, and in particular to a breathable, sound-absorbing, flame-retardant foam. Background Technology

[0002] Sound-absorbing and flame-retardant foam is a high-performance foam material that integrates sound absorption, heat insulation and flame retardancy. It is widely used in many fields such as construction, automobiles, home appliances, and audio equipment. Its main function is to effectively reduce noise transmission, improve environmental comfort, and enhance the fire safety of materials to a certain extent. Sound-absorbing and flame-retardant foam is usually made of polyurethane, polyethylene or other synthetic polymers, which are formed by special foaming processes.

[0036] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0037] Example 1

[0038] This utility model provides, for example Figure 1-2 The invention relates to a breathable, sound-absorbing, and flame-retardant foam, comprising a foam body 1, a slotted assembly, and a reinforcing assembly 3. The foam body 1 is made of polyurethane, polyethylene, and other synthetic polymers, giving it sound-absorbing and flame-retardant properties. The slotted assembly is formed on the foam body 1 and is used to dissipate heat and reduce the sound absorption effect. The reinforcing assembly 3 is disposed on the foam body 1 and is used to protect the foam body 1 from bending, thereby improving the overall strength of the foam body 1.

[0039] Specifically, the slot assembly includes a first transverse slot 21, a second transverse slot 22, a first venting slot 23, a first longitudinal slot 24, a second longitudinal slot 25, and a second venting slot 26. The first transverse slot 21 is located at the top of the foam body 1, the second transverse slot 22 is located at the bottom of the foam body 1, the first venting slot 23 is located on the side of the foam body 1, and the first transverse slot 21 communicates with the second transverse slot 22 through the first venting slot 23. The first longitudinal slot 24 is located at the top of the foam body 1, and the first longitudinal slot 24 and the first transverse slot 21 are arranged alternately. The second longitudinal slot 25 is located at the bottom of the foam body 1, and the second longitudinal slot 25 and the second transverse slot 22 are arranged alternately. The second venting slot 26 is located on the side of the foam body 1. The first longitudinal groove 24 is connected to the second longitudinal groove 25 through the second ventilation groove 26. Under the action of the first ventilation groove 23 and the second ventilation groove 26, the first transverse groove 21 and the first longitudinal groove 24 at the top of the foam body 1 can be connected to the second transverse groove 22 and the second longitudinal groove 25 at the bottom of the foam body 1, thereby connecting the two sides of the foam body 1, improving its air permeability. Since no holes are opened on the foam body 1, the sound insulation performance of the foam body 1 can be guaranteed. The first transverse groove 21, the second transverse groove 22, the first ventilation groove 23, the first longitudinal groove 24, the second longitudinal groove 25 and the second ventilation groove 26 can be formed by using the convex marks of the foaming mold during the foaming molding of the foam body 1, or they can be formed by post-cutting.

[0040] Furthermore, the reinforcing component 3 includes a foam column 31, a first reinforcing rod 32, and a second reinforcing rod 33. The outer wall of the foam column 31 is fixedly connected to the foam body 1. The first reinforcing rod 32 and the second reinforcing rod 33 are crisscrossed and fixedly connected to the foam column 31. The outer walls of the first reinforcing rod 32 and the second reinforcing rod 33 are interlocked with the foam body 1. The foam column 31 and the foam body 1 are made of the same material, and the height of the foam column 31 is the same as the thickness of the foam body 1. Thus, when the foam body 1 is foamed and molded, by installing the foam column 31, the first reinforcing rod 32, and the second reinforcing rod 33 in the foaming mold, the stability of the position of the first reinforcing rod 32 and the second reinforcing rod 33 inside the foam body 1 can be guaranteed.

[0041] Furthermore, the reinforcing component 3 also includes a first snap-fit ​​member 34, a second snap-fit ​​member 35, a snap block 36, and a connecting rod 38. The first snap-fit ​​member 34 is sleeved on the outside of the second reinforcing rod 33, and the second snap-fit ​​member 35 is sleeved on the outside of the first reinforcing rod 32. Both the first snap-fit ​​member 34 and the second snap-fit ​​member 35 are C-shaped. The snap block 36 is fixedly connected to the side of the second snap-fit ​​member 35, and there are two snap blocks 36 on both sides of the second snap-fit ​​member 35, so that the second snap-fit ​​member 35 can be snapped with the first snap-fit ​​member 34 through the snap block 36. The side of the first snap-fit ​​member 34 is provided with a slot 37 that matches the snap block 36, so as to ensure the stability of the snap-fit ​​between the first snap-fit ​​member 34 and the second snap-fit ​​member 35. The end of the connecting rod 38 is fixedly connected to the first snap-fit ​​member 34. The connecting rod 38 can ensure the stability of the connection between the two first snap-fit ​​members 34, thereby ensuring the stability of the foam column 31 foaming and forming outside the first reinforcing rod 32 and the second reinforcing rod 33.

[0042] Example 2

[0043] Unlike Example 1, as Figure 3-4 As shown, the slot assembly includes a third horizontal slot 27, a third vertical slot 28, and a vent 29. The third horizontal slot 27 is opened on the top of the foam body 1, and the third vertical slot 28 is opened on the top of the foam body 1. The third vertical slot 28 and the third horizontal slot 27 are arranged in a crisscross pattern. The vent 29 is opened at an angle on the foam body 1. The inner cavity of the vent 29 is connected to the misalignment of the third vertical slot 28 and the third horizontal slot 27, thereby ensuring the air permeability of the foam body 1. Since the vent 29 is opened at an angle, the inner wall of the vent 29 on the foam body 1 also has a certain sound absorption performance, thereby ensuring the sound absorption performance of the foam body 1.

[0044] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
