Description

Technical Field

[0001] The utility model relates to the technical field of fiberboards, in particular to a water-resistant and moisture-proof fiberboard structure. Background Art

[0002] Waterproof fiberboard is a decoration material with good moisture resistance and wear resistance. It can effectively prevent material expansion caused by moisture intrusion and avoid structural damage. Moisture-proof board is a man-made board. Fiberboard is mainly made of wood fiber as raw material and other adhesives. Some of them need to be composited and pressed to integrate a new fiberboard in order to achieve wear resistance or corrosion resistance to meet the requirements of practicality and aesthetics of decoration.

[0003] The existing common fiberboards have the following problems:

[0004] 1. The existing fiberboard is not strong enough to resist water absorption from the gaps around it due to the damp ground or high moisture content in the air. The expansion force after moisture absorption causes the fiberboard to deform. In addition, the surface of the fiberboard is frequently rubbed during use after the decoration construction. Therefore, the wear resistance of the fiberboard made of a single material is not as strong as that of the fiberboard made of multiple materials. At the same time, in order to facilitate the connection of the composite fiberboard unit into a whole, the splicing structure needs to ensure that the front installation error will not cause the direction error.

[0005] 2. After the composite fiberboard is compressed and manufactured, due to the differences in the properties of different materials, there is a possibility that the composite material will become loose. Therefore, it is best to strengthen the structure of the composite fiberboard while also strengthening the shear strength to avoid material cracking during transportation or processing.
