Description

Technical Field

[0001] The utility model relates to the technical field of building boards, in particular to a polymer self-cleaning pre-coated board. Background Art

[0002] Pre-coated board is a kind of building board. The surface coating performance of pre-coated board has good acid and alkali resistance, corrosion resistance, chemical resistance and antibacterial properties. After using pre-coated board, there is no need to worry about the damage to the wall caused by corrosive agents. It is mainly used for wall decoration in medical clean rooms, operating rooms, ICU wards and corridors. Polymers can be divided into three categories: plastics, rubber and fibers. Polymer pre-coated board has a fine and compact board structure, so polymer pre-coated board has excellent fire and moisture resistance, ensuring the excellent environment of medical places.

[0003] In the prior art, for example, Chinese patent CN209686764U discloses a ceramic self-cleaning roller-coated panel, comprising a metal substrate layer, a first pre-treatment passivation layer covering one surface of the metal substrate, and a back paint layer covering the surface of the first pre-treatment passivation layer, and also comprising a second pre-treatment passivation layer covering the other surface of the metal substrate, a primer layer covering the surface of the second pre-treatment passivation layer, a top paint layer covering the surface of the primer layer, a ceramic self-cleaning clear varnish layer covering the surface of the top paint layer, and a protective film layer covering the surface of the ceramic self-cleaning clear varnish layer.

[0004] However, in the prior art, for the polymer pre-coated plates used in medical places, the sound insulation effect of the polymer structure itself is poor. After the sound in the corridor encounters the wall, it will be reflected into the narrow space, resulting in noisy sound in the corridor. The generated noise will not only affect the physical and mental health of patients, but also affect the work efficiency of medical staff. Utility Model Content

[0005] The purpose of the utility model is to solve the problem in the prior art that due to the poor sound insulation effect of the structure of the polymer itself, the sound in the corridor will be reflected into the narrow space after encountering the wall, resulting in noisy sound in the corridor. The generated noise will not only affect the physical and mental health of patients, but also affect the work efficiency of medical staff, and a polymer self-cleaning pre-coated plate is proposed.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a polymer self-cleaning pre-coated board, including a substrate, the top and bottom surfaces of the substrate are provided with sound absorption cavities, the bottom surface of the substrate is fixedly connected to a back sealing plate, the top surface of the substrate is fixedly connected to a surface plate, and a plurality of densely distributed sound absorption cavities are arranged on the surface of the substrate. The substrate and the sound absorption cavities together constitute a board with porous cavities on the surface, which can not only save material costs, but also reduce the weight of the board itself and reduce the difficulty of transportation. The cavity can provide an additional sound absorption layer, thereby improving the sound projection rate of the pre-coated board, reducing the propagation of noise, and providing a schematic working environment for corridors.

[0007] Preferably, the top surface of the surface plate is compounded with a protective film. The protective film is arranged on the top surface of the surface plate to avoid the problem of dust and impurities adsorbing and polluting, so that the pre-coated plate has a certain self-cleaning function.

[0008] Preferably, the bottom surface of the back cover plate is compounded with a textured embossed layer, and the surface of the textured embossed layer is provided with strip grooves. The textured embossed layer is arranged on the bottom surface of the back cover plate to improve the stability of the overall structure, avoid the problem of warping and deformation of the plate due to different expansion rates after absorption, and improve the service life of the plate.

[0009] Preferably, the bottom surface of the textured embossed layer is fixedly connected with a convex strip, and the convex strip is a striped pointed conical rod-shaped structure. The surface of the back sealing plate is designed to be an uneven structure, which increases the surface area of ​​the back sealing plate in contact with the air under the same area and improves the heat dissipation efficiency.

[0010] Preferably, UV light shadow glue is compounded between the surface plate and the back cover plate to improve the overall sealing of the pre-coated plate.

[0011] Compared with the prior art, the advantages and positive effects of the utility model are:

[0012] 1. In the utility model, a sound-absorbing cavity is arranged on the surface of the substrate to provide an additional sound-absorbing layer for the environment, thereby improving the sound projection rate of the pre-coated board, reducing the propagation of noise, providing a convenient working environment for corridors, saving material costs, reducing the weight of the board itself, and reducing the difficulty of transportation. The problem of poor sound transmission of the polymer pre-coated board can be solved, and a good working environment can be provided for medical places.

[0013] 2. In the utility model, the surface plate is sleeved on the outside of the base plate and the back plate to improve the stability of the structure of the pre-coated plate itself, and a textured embossed layer is provided on the bottom surface of the back plate to improve the stability of the overall structure, avoid the problem of the plate warping and deformation due to different expansion rates after absorption, and improve the service life of the plate.
