Description

Technical Field

[0001] This utility model belongs to the field of gypsum board technology, and specifically relates to composite paper-faced gypsum board. Background Technology

[0002] With the rapid development of the modern construction industry, people's demands for the comfort of their living and working environments are constantly increasing. Among the many factors affecting the living and working experience, sound insulation is crucial. Whether in residential, commercial, or public facilities, good sound insulation can effectively reduce external noise interference, creating a quiet and private space for people.

[0003] However, the widely used paper-faced gypsum board on the market has significant shortcomings in sound insulation performance. Ordinary paper-faced gypsum board mainly consists of a surface paper layer, a gypsum core layer, and a bottom paper layer. Its structure and material characteristics determine that it is difficult to effectively block the transmission of sound. When faced with various noise sources such as traffic noise, neighborhood activity noise, and equipment operating noise, the sound insulation ability of ordinary paper-faced gypsum board is inadequate and cannot meet people's pursuit of a quiet environment. Utility Model Content

[0004] This utility model addresses the problems of existing technologies by providing composite paper-faced gypsum board, with the specific technical solution as follows:

[0005] Composite paper-faced gypsum board includes a board body, which comprises a face paper layer, a reinforcing layer, a gypsum core layer, and a sound insulation layer stacked sequentially. The gypsum core layer is a three-layer structure formed by foaming, including a surface layer, a middle layer, and a bottom layer. The middle layer has hollow channels. The sound insulation layer includes a film layer and a honeycomb layer. The film layer is a polypropylene film, and the honeycomb layer is a PET honeycomb core. The hollow channels are aligned with the honeycomb structure in the sound insulation layer to form a sound wave dissipation channel.

[0006] As a further technical solution of this utility model, the density of the surface layer and the bottom layer is greater than the density of the middle layer.

[0007] As a further technical solution of this utility model, the surface of the face paper layer has embossing, and the surface of the face paper layer is provided with a composite coating, which is a composite nano-coating of titanium dioxide and graphene.

[0008] As a further technical solution of this utility model, the reinforcing layer is basalt fiber cloth.

[0009] As a further technical solution of this utility model, an auxiliary installation component is provided on the outside of the plate body. The auxiliary installation component includes a plug plate, a slot, a positioning post and a flared mouth. The plug plate and the slot are distributed on two opposite sides of the plate body. In the installation state, the plug plates of one set of plates are inserted into the slots of another set of plates.

[0010] As a further technical solution of this utility model, the cross-section of the insert plate is a trapezoidal structure, and a rubber pad is provided in the slot. In the installed state, the insert plate is pressed into the slot and forces the rubber pad to deform.

[0011] As a further technical solution of this utility model, the positioning posts and the flared openings are distributed on two opposite sides of the plate. In the installation state, the positioning posts of one set of plates are inserted into the flared openings of another set of plates. The positioning posts are conical structures.

[0012] The beneficial effects of this utility model are as follows:

[0013] In this application, a sound wave dissipation channel is formed by aligning the hollow channel in the middle layer with the honeycomb structure in the sound insulation layer. When sound propagates to this channel, the hollow channel first disrupts the sound wave propagation path, causing it to be reflected and refracted. The honeycomb structure aligned with it, with its numerous tiny pores, further increases the number of sound wave reflections and scatterings, greatly dissipating sound wave energy and effectively blocking noise of different frequencies.

[0018] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0019] Figure 1 A schematic diagram of the overall structure of composite paper-faced gypsum board is shown; Figure 1In this composite gypsum board, an auxiliary installation assembly 200 is provided on the outside of the board body 100. The auxiliary installation assembly 200 includes insert plates 210, slots 220, positioning posts 230, and flared openings 240. The insert plates 210 and slots 220 are distributed on two opposite sides of the board body 100. In the installed state, the insert plates 210 of one set of board bodies 100 are inserted into the slots 220 of another set of board bodies 100. That is, the insert plates 210 and slots 220 are a matching mortise and tenon structure, which allows two spliced ​​board bodies 100 to be connected through the insert plates 210 and slots 220, preventing movement of the two along the thickness direction. The cross-section of the insert plate 210 is a trapezoidal structure. The special thickness reduction structure of the trapezoidal structure makes it easier for the insert plate 210 to be inserted into the slot 220, which is beneficial for the connection of two adjacent board bodies 100. The slots 220 are provided with With a rubber pad, in the installed state, the insert plate 210 is pressed into the slot 220, forcing the rubber pad to deform. This deformation further enhances the tightness of the connection between the insert plate 210 and the slot 220, preventing loosening. Positioning posts 230 and flared openings 240 are distributed on two opposite sides of the plate 100. In the installed state, the positioning posts 230 of one set of plates 100 are inserted into the flared openings 240 of another set of plates 100. That is, the positioning posts 230 and flared openings 240 are a matching splicing structure, enabling two spliced ​​plates 100 to be positioned using the positioning posts 230 and flared openings 240, preventing misalignment during splicing. The positioning posts 230 have a tapered structure. Utilizing the special diameter-decreasing design of the tapered structure, the positioning posts 230 are more easily inserted into the flared openings 240, facilitating the positioning of adjacent plates 100.

[0020] Figure 2 A schematic diagram of the internal structure of composite paper-faced gypsum board is shown. Figure 2In the composite gypsum board 100, the board body 100 includes a face paper layer 110, a reinforcing layer 120, a gypsum core layer 130, and a sound insulation layer 140 stacked sequentially. The face paper layer 110 has an embossed surface. The embossing process changes the paper fiber structure, which to a certain extent enhances the tensile and tear strength of the paper, thereby improving the overall mechanical strength of the composite paper-faced gypsum board and enhancing the interfacial adhesion. The face paper layer 110 has a composite coating 111, which is a composite nano-coating of titanium dioxide and graphene. This makes it difficult for dust and stains to adhere to the face paper, and they can be easily removed by rain or simple wiping, keeping the gypsum board surface clean and reducing cleaning and maintenance costs. The reinforcing layer 120... 0 represents basalt fiber cloth; basalt fiber cloth significantly improves the flexural and compressive strength of gypsum board, reduces deformation and cracking, and extends service life. It is non-combustible and enhances the fire resistance of gypsum board in a fire, slowing the spread of fire; it effectively blocks heat transfer, improving the thermal insulation effect of gypsum board, thus reducing energy consumption in buildings and playing a role in energy saving; it also has sound absorption and blocking effects, effectively reducing noise in conjunction with the inherent properties of gypsum board; the gypsum core layer 130 is a three-layer structure formed by foaming, including a surface layer 131, a middle layer 132, and a bottom layer 133. The density of the surface layer 131 and the bottom layer 133 is greater than that of the middle layer 132; for example, the density of the surface layer 131 is 0.6 g / cm³. 3 The density of the middle layer 132 is 0.4 g / cm³. 3 The density of the bottom layer 133 is 0.5 g / cm³. 3 The low-density middle layer 132 has a more porous structure. These pores effectively block the transmission of sound and heat. As sound and heat pass through layers of different densities, they are constantly reflected and refracted, significantly improving the sound and heat insulation performance of the gypsum board, making the indoor space quieter and more comfortable, and reducing energy consumption. The sound insulation layer 140 includes a film layer 141 and a honeycomb layer 142. The film layer 141 is a polypropylene film, and the honeycomb layer 142 is a PET honeycomb core. The honeycomb pores of the PET honeycomb core effectively block the transmission of sound and heat. Sound and heat are constantly reflected and refracted in these pores, thus significantly improving the sound and heat insulation performance of the gypsum board. The sound insulation and heat insulation effects of gypsum board are improved. The polypropylene film layer 141 also has certain heat insulation properties. Working together with the PET honeycomb core, it makes the indoor space quieter and more comfortable, and can also reduce energy consumption. The middle layer 132 is provided with hollow channels. The hollow channels are aligned with the honeycomb structure in the sound insulation layer 140 to form a sound wave dissipation channel. When sound propagates to this channel, the hollow channels first disrupt the sound wave propagation path, causing it to be reflected and refracted. The honeycomb structure aligned with it, with its numerous tiny pores, further increases the number of sound wave reflections and scatterings, greatly dissipating sound wave energy and effectively blocking noise of different frequencies.

[0021] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
