Description

Technical Field

[0001] The utility model relates to the technical field of composite plywood, in particular to a mildew-proof and flame-retardant composite plywood. Background Art

[0002] Traditional composite panels are mostly made of particle boards, which have poor structural strength and poor mildew resistance. Utility Model Content

[0003] The technical problem to be solved by the utility model is: in order to overcome the above problems, a mildew-proof and flame-retardant composite plywood is provided, which solves the above problems.

[0004] The utility model solves the technical problem by adopting the following technical solutions:

[0005] A mildew-proof and flame-retardant composite plywood comprises an upper wooden panel, a lower wooden panel and bamboo strips, wherein the bamboo strips are stacked and arranged in strips, the upper wooden panel and the lower wooden panel press the bamboo strips in the middle, and a sinking platform is provided in the lower wooden panel and the upper wooden panel, and the side walls of the bamboo strips are against the side walls of the sinking platform in the upper wooden panel and the lower wooden panel.

[0006] Preferably, the depth of the sunken platform in the lower wooden panel is the same as that of the sunken platform in the upper wooden panel.

[0007] Preferably, a flame-retardant quartz fiber sheet is embedded and bonded between two adjacent bamboo strips. The quartz fiber sheet can effectively help release stress of the board during hot pressing while being flame-retardant, thereby improving the fit of the bonding surface and reducing the gap.

[0008] Preferably, the height of the quartz fiber sheet is the same as the height of the bamboo strip, and the length of the quartz fiber sheet is the same as the length of the bamboo strip.

[0009] Preferably, the bamboo strips do not contain bamboo skin parts, and the water content does not exceed ten percent.

[0010] Preferably, the bamboo strips are impregnated with a flame retardant, and the fibers of the bamboo strips can better absorb the flame retardant, thereby making the bamboo strips more anti-corrosive and fireproof.

[0011] The advantages and positive effects of the utility model are: the corrosion resistance of the composite board is improved by utilizing the good corrosion resistance of the bamboo structure with low water content, the fire resistance is further improved by the quartz fiber sheets arranged at intervals, and the structural strength is improved by increasing the bonding contact surface. The original fiber structure of the bamboo strip structure greatly increases the strength of the board. Compared with the existing technology, the strength, corrosion resistance and flame retardancy are improved. BRIEF DESCRIPTION OF THE DRAWINGS
