Background

The medium density fiberboard is called medium density fiberboard for short. The medium density fiberboard is manufactured by taking wood fiber or other plant fiber as a raw material, crushing, separating fiber, drying, applying urea formaldehyde resin or other applicable adhesive, and hot-pressing. The density of the fiber board is generally in the range of 500-880 kg/cubic meter, the thickness of the fiber board is generally 5-30 mm, the surface of the fiber board after being pressed is uneven, the single fiber board is poor in waterproofness and easy to deform due to water absorption expansion, and in order to improve the performance, most of fiber boards put into use are composite board bodies, namely, waterproof boards, various functional boards or adhesive films are compounded on the surfaces of the fiber boards to improve the performances of the fiber boards, for example, chinese patent publication No. CN214354694U discloses a waterproof density fiber board which comprises a corrosion-resistant layer, a buffer layer is arranged below the corrosion-resistant layer, the upper surface of the buffer layer is adhered to the lower surface of the corrosion-resistant layer, a thermal insulation layer is arranged below the buffer layer, and the upper surface of the thermal insulation layer is adhered to the lower surface of the buffer layer.
