Description

Technical Field

[0001] The utility model relates to the technical field of composite felt production, and more specifically, it relates to a new type of refractory glass wool felt. Background Art

[0002] A glass fiber felt is a sheet product made by randomly binding continuous filaments or chopped filaments together through a chemical binder or mechanical action. Its characteristics such as lightweight, flame retardant, heat insulation, sound absorption, and waterproof make it an ideal choice for building wall insulation materials, building roof waterproof materials, and floor sound insulation materials.

[0003] In the prior art, a glass wool roll felt is a roll made to meet the need for large-area laying. It is lighter than a glass wool board, has greater elasticity, and a higher level of resilience. When it is produced, it becomes an integral whole through the connection and combination of each layer. However, after the connection of each layer is completed, when subjected to longitudinal tension, the layers are prone to separation under stress, affecting the stability of the connection between the layers.

[0004] Therefore, a new type of refractory glass wool felt is needed to solve the above problems. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a new type of refractory glass wool felt to solve the problems put forward in the above background art.

[0006] The above technical purpose of the utility model is achieved through the following technical solutions:

[0007] A new type of refractory glass wool felt includes a base material layer and an aluminum foil layer located below it. The aluminum foil layer is provided with a number of partition convex parts distributed in an array. The base material layer includes a first base layer and a second base layer. Each of the first base layer and the second base layer includes a number of glass fiber strips. The number of glass fiber strips on the first base layer is perpendicular to the number of glass fiber strips on the second base layer. A number of the partition convex parts are simultaneously located between adjacent glass fiber strips of the first base layer and adjacent glass fiber strips of the second base layer. A number of the partition convex parts are connected by a pressing strip, and the pressing strip is located on the surface of the first base layer. The length direction of the pressing strip is perpendicular to the length direction of the number of glass fiber strips of the first base layer.

[0008] The technical solution of the utility model is further set as: a through hole penetrating the partition convex part is opened on the partition convex part, and the pressing strip penetrates through the through hole.

[0009] The technical solution of the utility model is further set as: the height of the partition convex part is less than or equal to the sum of the thicknesses of the first base layer and the second base layer.

[0010] The technical solution of the present utility model is further set as follows: The pressing strip forms pressing grooves on the surfaces of several glass fiber strips of the first base layer, and the pressing strip is made of graphene material.

[0011] The technical solution of the present utility model is further set as follows: The bottom end of the separating convex part is fixedly connected with an extension part for increasing the contact area.

[0012] The technical solution of the present utility model is further set as follows: Sound-absorbing strips are arranged between adjacent glass fiber strips of the first base layer, the sound-absorbing strips and the separating convex parts are arranged alternately, and a plurality of sound-absorbing holes are formed in the sound-absorbing strips.

[0013] The technical solution of the present utility model is further set as follows: A reinforcing surface layer is arranged on the surface of the first base layer away from the second base layer, a glass fiber mesh layer is arranged on the surface of the second base layer away from the first base layer, a plurality of the separating convex parts are bonded to the glass fiber mesh layer, and the reinforcing surface layer and the glass fiber mesh layer are stitched and connected.

[0014] Due to the adoption of the above technical solution, the technical progress achieved by the present utility model compared with the prior art is:

[0015] Through the setting of the above structure, the pressing strip arranged inside the glass wool felt can apply pressure to the glass fiber strips in both the first base layer and the second base layer at the same time, preventing the separation and dispersion of the first base layer and the second base layer, ensuring the stability of the connection. At the same time, the stitched reinforcing surface layer and the glass fiber mesh layer can further reinforce the first base layer and the second base layer, making the internal connection of the glass wool felt more stable, with strong tensile performance and good anti-detachment effect.

[0016] Through the setting of the above structure, the pressing strip made of graphene material can transfer and disperse heat, thereby cooling the local high temperature of the glass wool felt, avoiding the deterioration of the local heat insulation effect caused by excessive local temperature. In this way, the heat insulation effect of the glass wool felt can be further improved, and the pressing grooves formed by the pressing strip can store a certain amount of air. Utilizing the characteristic that the thermal conductivity of air is relatively poor, the fire and heat insulation effect of the glass wool felt is further enhanced. In addition, the sound-absorbing strip can also reflect and consume noise multiple times through the sound-absorbing holes, thereby reducing noise and improving the sound insulation effect of the glass wool felt.

[0023] In order to better understand the technical means of the present utility model and implement it according to the content of the specification, the following further describes the specific embodiments of the present utility model in detail with reference to the drawings and embodiments. The following embodiments are used to illustrate the present utility model but not to limit the scope of the present utility model. Embodiment

[0024] As Figures 1 to 5 shown, the present utility model provides a new type of fireproof glass wool felt, which includes a base material layer and an aluminum foil layer 1 located below it. The base material layer includes a first base layer 3 and a second base layer 4. Both the first base layer 3 and the second base layer 4 include a plurality of glass fiber strips 5. The plurality of glass fiber strips 5 on the first base layer 3 are perpendicularly arranged to the plurality of glass fiber strips 5 on the second base layer 4. A reinforcing surface layer 12 is provided on the surface of the first base layer 3 away from the second base layer 4, and a fiberglass mesh layer 13 is provided on the surface of the second base layer 4 away from the first base layer 3. The fiberglass mesh layer 13 is bonded to the aluminum foil layer 1, and the reinforcing surface layer 12 is stitched to the fiberglass mesh layer 13.

[0025] Through the above structural arrangement, the stitching connection between the reinforcing surface layer 12 and the fiberglass mesh layer 13 can increase the connection strength between the first base layer 3 and the second base layer 4 inside the glass wool felt, prevent the internal separation and dispersion of the glass wool felt during use, and ensure its stability during use.

[0026] As Figures 1 to 5 shown, a plurality of partition convex parts 2 are adhesively bonded to the fiberglass mesh layer 13 and are arranged in an array. The bottom end of the partition convex part 2 is fixedly connected with an extension part 9 for increasing the contact area. A plurality of partition convex parts 2 are simultaneously located between the adjacent glass fiber strips 5 of the first base layer 3 and the adjacent glass fiber strips 5 of the second base layer 4. A plurality of partition convex parts 2 are connected by a pressing strip 6, and the pressing strip 6 is located on the surface of the first base layer 3. The length direction of the pressing strip 6 is perpendicular to the length direction of the plurality of glass fiber strips 5 of the first base layer 3.

[0027] Through the setting of the above structure, the separation convex portions 2 on the fiberglass mesh layer 13 can simultaneously separate the fiberglass strips 5 on the first base layer 3 and the fiberglass strips 5 on the second base layer 4. In this way, the pressure strip 6 connecting adjacent separation convex portions 2 can press on the surface of the fiberglass strips 5 on the first base layer 3 to restrict them, while the fiberglass strips 5 on the first base layer 3 are pressed on the fiberglass strips 5 on the second base layer 4 to restrict them, so as to achieve the reinforcement effect on the first base layer 3 and the second base layer 4, prevent the two from dispersing and separating from each other, improve the tensile property of this glass wool felt, and ensure the stability of the connection.

[0028] As Figures 1 to 5 shown, the height of the separation convex portion 2 is less than or equal to the sum of the thicknesses of the first base layer 3 and the second base layer 4. A through hole 7 penetrating it is provided on the separation convex portion 2. The pressure strip 6 passes through the through hole 7 and forms a pressure groove 8 on the surface of several fiberglass strips 5 on the first base layer 3. The pressure strip 6 is made of graphene material.

[0029] Through the setting of the above structure, because the height of the separation convex portion 2 is relatively low, when the pressure strip 6 passes from the surface of the first base layer 3, a pressure groove 8 will be formed on the fiberglass strip 5 to which it belongs. Since there is a gap between the formed pressure groove 8 and the reinforcement surface layer 12, it can store a certain amount of air, so as to utilize the characteristic of poor thermal conductivity of air to improve the fire resistance and heat insulation of this glass wool felt. At the same time, because the pressure strip 6 is made of graphene material, the pressure strip 6 can transfer and disperse the local heat, avoiding too high local temperature and affecting the use effect of this glass wool felt.

[0030] As Figures 1 to 5 shown, a sound-absorbing strip 10 is provided between adjacent fiberglass strips 5 on the first base layer 3. The sound-absorbing strip 10 and the separation convex portion 2 are arranged alternately, and a plurality of sound-absorbing holes 11 are provided on the sound-absorbing strip 10. The sound-absorbing strip 10 can be made of sound-absorbing cotton or sponge.

[0031] Through the setting of the above structure, while this glass wool felt has good tensile strength and heat insulation performance, it also uses the sound-absorbing strip 10 to have good sound insulation and noise reduction effects, and can reflect and consume the noise multiple times, which is suitable for use in fields such as building walls.

[0032] The above description is only the preferred implementation mode of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions falling within the idea of the present invention belong to the protection scope of the present invention. It should be noted that for those of ordinary skill in the art in this technical field, several improvements and refinements made without departing from the principle of the present invention should also be regarded as within the protection scope of the present invention.
