As shown in Figures 1 and 2, this embodiment provides an antibacterial and antiviral clean composite board, including an upper fiberboard 1, a lower fiberboard 2, a calcium silicate board 5 and a paperboard 6, a sound insulation layer 3 is provided between the upper fiberboard 1 and the lower fiberboard 2, the paperboard 6 includes a paper layer and an antibacterial and antiviral coating coated on the paper layer, the paperboard 6 and the calcium silicate board 5 are bonded by a hot pressing process, and the upper fiberboard 1 and the lower fiberboard 2 are both covered with a calcium silicate board 5 with a paperboard 6.

In this embodiment, the upper fiberboard 1 and the lower fiberboard 2 are artificial boards made of wood cellulose fibers interwoven and formed using their inherent adhesive properties, and adhesives or additives are added during the manufacturing process, so that the upper fiberboard 1 and the lower fiberboard 2 have the advantages of uniform material, high strength, small longitudinal and transverse strength difference, and not easy to crack. A sound insulation layer 3 is set between the upper fiberboard 1 and the lower fiberboard 2. Specifically, sound insulation cotton can be filled between the upper fiberboard 1 and the lower fiberboard 2 to absorb external sound waves and enhance the sound insulation effect. The outer sides of the upper fiberboard 1 and the lower fiberboard 2 are covered with a calcium silicate board 5, and a paperboard 6 is pasted on the outer surface of the calcium silicate board 5. In this embodiment, the paperboard 6 and the calcium silicate board 5 are formed by high-temperature hot pressing. The paperboard 6 can be softened under high temperature conditions and is tightly bonded to the surface of the calcium silicate board 5 under the action of hot pressing. At the same time, the paperboard 6 can also fill the defects on the surface of the calcium silicate board 5 through the action of hot pressing, so that the surface of the composite board can be smooth and soft, which effectively solves the problem that the surface of the existing antibacterial board is hard and the surface layer is easy to wear and fall off; and the paperboard 6 has an antibacterial and antiviral coating, which can have an antibacterial and antiviral effect.

Preferably, the antibacterial and antiviral coating can be made of photocatalytic materials, which can produce hydroxyl radicals with high reactivity under visible light irradiation, and can kill bacteria and viruses, and the effect is long-lasting and significant; wherein, the photocatalytic material can be preferably a photocatalytic nanocomposite material, such as the patented product (CN116588904A carbon nitride antibacterial and antiviral nanocomposite material) declared by the applicant, the main components of which are titanium dioxide, graphite phase carbon nitride, etc., which increase visible light absorption and enhance the photocatalytic effect, thereby achieving rapid inactivation of bacteria and viruses. The antibacterial and antiviral coating is made by mixing the photocatalytic material and the glue, and the antibacterial and antiviral coating with adhesive function is made by the dipping process, and the antibacterial and antiviral coating is applied to the adhesive paper layer to make the adhesive paperboard; since the adhesive paperboard 6 and the calcium silicate board 5 are combined by high temperature hot pressing, during this high temperature hot pressing process, the antibacterial and antiviral coating of the adhesive paperboard 6 is also combined with the adhesive paper layer by the hot pressing process, so the antibacterial and antiviral coating is firmly bonded, the antibacterial and antiviral performance is lasting, the skateboard is efficient, and it is anti-insect and convenient to use for a long time.

Furthermore, in order to enhance the aesthetics of the composite board, a plurality of patterns may be pressed on the surface of the paperboard 6 . Different patterns may be formed on the surface of the paperboard 6 according to different requirements.

In an optimized implementation, a plurality of herringbone support plates 4 are arranged between the upper fiberboard 1 and the lower fiberboard 2. The support plates 4 are provided to support the upper fiberboard 1 and the lower fiberboard 2 on both sides, thereby ensuring that the overall thickness and strength of the composite board meet the requirements. At the same time, the support plates 4 are designed to be herringbone supports to give full play to the stability of the triangle, thereby further improving the strength of the composite board.

Furthermore, a fiber layer end plate 7 can be arranged on the end surface between the two layers of the adhesive paperboard 6. On the one hand, the fiber layer end plate 7 can also support the upper and lower layers of the composite board, further improving the strength of the composite board. On the other hand, by setting the fiber layer end plate 7, the end surface of the composite board is closed, thereby protecting the internal structure of the composite board and improving the service life of the composite board.
