TECHNICAL FIELD

[0001] The utility model relates to plate processing technical field, concretely is a kind of high-density mildew-proof bamboo board. BACKGROUND

[0002] Bamboo board is the board that a piece of piece processing and handling exquisite bamboo piece is glued and pressed, with environmental protection, high hardness, not easy to deform and crack, antibacterial, texture beautiful and other advantages, can be used in indoor decoration and furniture manufacturing and other fields;Bamboo board is rich in starch, protein and other nutrients, and has hygroscopicity, is easy to mildew in storage, transportation and use by environmental influence, to cause resource waste and economic loss, therefore need to do bamboo board mildew-proof work, to ensure the use and economic value of bamboo board and its products;

[0003] The surface of bamboo board in prior art is mostly plane structure, when water drop is splashed on its surface, can stay on its surface for a long time, finally can penetrate into the inside of bamboo board, to cause board mildew;And the mildew-proof measure of existing bamboo board is single, only simple protective layer is brushed on surface, cannot prevent water vapor from entering from the side of each board layer, to cause poor mildew-proof performance, for this purpose, we propose a kind of high-density mildew-proof bamboo board. UTILITY MODEL CONTENT

[0004] The utility model solves the technical problem of overcoming the defects of prior art, provides a kind of high-density mildew-proof bamboo board, and the surface and side edge of bamboo board are provided with mildew-proof measures, cooperate with the pretreatment measure of each board, can effectively improve the mildew-proof performance of bamboo board: the end face of upper and lower board on the surface of board is arc structure, can make water drop slide to both sides, effectively prevent splashed water drop to stay on the surface of board, avoid mildew to occur caused by water entering board surface;And by brushing silver ion-containing mildew-proof coating on surface, can form physical-chemical double barrier, block water and mold spore invasion;At side structure, by brushing hot melt adhesive layer, can close the gap between board layer, prevent water vapor from entering the inside of board and cause mildew, and by the installation of metal edge and the pressing of sealing groove, can further improve the airtightness of board edge, to ensure good mildew-proof effect, can effectively solve the problems in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-density anti-mildew bamboo board, comprising a core, a lower panel, an upper panel, an adhesive layer, and an anti-mildew coating. The core, lower panel, and upper panel are all made of bamboo. The core is located in the middle layer. An upper panel is located on the upper side of the core, and a lower panel is located on the lower side of the core. Both the upper and lower panels are bonded to the core by the adhesive layer. The upper end of the upper panel has a slightly raised curved surface structure. A micro-arc groove is formed on the lower side of the lower panel, with the groove centered. The bottom of the lower panel and both sides of the groove are horizontal structures. An anti-mildew coating is applied to the upper curved surface of the upper panel and the lower concave surface of the lower panel. The anti-mildew coating is a nano-scale water-based paint containing silver ions.

[0006] The adhesive layer is used to bond and fix the lower and upper panels to the core. The three layers are stacked on top of each other, which can effectively improve the structural strength of the bamboo board. By applying a silver ion-containing anti-mildew coating to the surface, a physical-chemical dual barrier can be formed to block the invasion of moisture and mold spores. The ends of the upper and lower panels are both arc-shaped, which allows water droplets to slide off to both sides, effectively preventing water droplets from remaining on the board surface and avoiding mold growth caused by water entering the board surface. The horizontal sections on both sides of the bottom of the lower panel can ensure good load-bearing performance when the bamboo board is laid flat.

[0007] Furthermore, it also includes a hot melt adhesive layer. The core, lower laminate, and upper laminate together form a composite board structure, and a hot melt adhesive layer is applied to the front, back, left, and right sides of the composite board. By applying the hot melt adhesive layer to the sides of the three-layer board, the gaps between the boards can be sealed, preventing moisture from entering the board and causing mold.

[0008] Furthermore, it also includes metal edge banding, with metal edge banding covering all four edges of the composite board. The metal edge banding can further tighten and fix the edges of the composite board, and can also cover and protect the hot melt adhesive layer applied to the sides, thus providing a double waterproof and mildew-proof effect on the sides of the bamboo board.

[0009] Furthermore, it also includes sealing grooves. Two sealing grooves are pressed at the metal edge banding on both the front and back sides of the composite board, with the bottom of the sealing grooves interlocking with the outside of the composite board. By pressing sealing grooves at the metal edge banding, the sealing performance of the board edges can be further improved.

[0010] Furthermore, the core, lower panel, and upper panel are all impregnated with an antifungal agent, followed by high-temperature carbonization. By impregnating each layer of the board with the antifungal agent, the board can have an antibacterial effect; the high-temperature carbonization treatment at 160-200℃ can carbonize the bamboo at high temperatures, destroying the internal sugars, starches, and other nutrient sources for mold, reducing the risk of mold growth, and improving the stability of the bamboo.

[0011] Further, the plate core, the lower combined plate and the upper combined plate are fixed based on the adhesive layer and high-density pressing is carried out. Through the high-pressure gluing process, the bamboo pieces are compressed, the porosity is reduced, and the attachment and growth of mold are inhibited.

[0012] Compared with the prior art, the high-density mold-proof bamboo board has the following advantages:

[0013] 1. The end faces of the upper combined plate and the lower combined plate on the surface of the board are arc-shaped structures, which can make water droplets slide to both sides, effectively prevent the water droplets from remaining on the surface of the board, and avoid mold growth caused by water entering the board surface; and the silver ion-containing mold-proof coating is coated on the surface to form a physical-chemical double barrier to block the invasion of moisture and mold spores.

[0014] 2. At the side structure, the hot melt adhesive layer is coated to seal the gaps between the board layers and prevent water vapor from entering the inside of the board to cause mold; and the metal edge is additionally installed and the sealing groove is pressed to further improve the airtightness of the edge of the board to ensure good mold-proof effect.

[0015] 3. The mold-proof measures are provided on the surface and the side edge of the bamboo board, and the pretreatment measures of the various layers of the board are combined to effectively improve the mold-proof performance of the bamboo board: the end faces of the upper combined plate and the lower combined plate on the surface of the board are arc-shaped structures, which can make water droplets slide to both sides, effectively prevent the water droplets from remaining on the surface of the board, and avoid mold growth caused by water entering the board surface; and the silver ion-containing mold-proof coating is coated on the surface to form a physical-chemical double barrier to block the invasion of moisture and mold spores; at the side structure, the hot melt adhesive layer is coated to seal the gaps between the board layers and prevent water vapor from entering the inside of the board to cause mold; and the metal edge is additionally installed and the sealing groove is pressed to further improve the airtightness of the edge of the board to ensure good mold-proof effect.
