Environment-friendly Chinese-character-'ri'-shaped composite flat plate

Abstract

The invention discloses an environment-friendly Chinese-character-'ri'-shaped composite flat plate. The composite flat plate comprises a face plate, a bottom plate and a center layer arranged between the face plate and the bottom plate, wherein the face plate and the bottom plate are respectively adhered to the center layer through glue, the center layer is of a honeycombed paper core and comprises a frame which is arranged at the periphery of the honeycombed paper core and is glued to the periphery of the honeycombed paper core, the periphery of the frame is square, a reinforcing strip which connects two opposite sides of the frame is arranged in the frame, and the thickness of the frame and the thickness of the reinforcing strip are equal to that of the honeycombed paper core; and each of the face and bottom plates comprises at least one layer of paper board or paper skin. According to the environment-friendly Chinese-character-'ri'-shaped composite flat plate, the center layer is of the honeycombed paper core, the face plate and the bottom plate are paper boards or paper skins, and sources of raw materials of the center layer, the face plate and the bottom plate are paper products, so that the weight is light, the cost is low, and timber is not directly used so as to benefit for the protection on forest resources; and the strength of the composite flat plate reaches and is even higher than that of a timber composite plate.

Description

technical field [0001] The invention relates to a composite plate, in particular to an environment-friendly Japanese-shaped composite plate. Background technique [0002] From the comprehensive consideration of the recycling of raw materials, the impact of raw material sources on the environment, and the light weight and low transportation cost, paper composite flat panels are widely used, such as the Chinese utility model patent with publication number CN201889920U, and honeycomb composite panels for furniture. , including a panel, a bottom plate and a honeycomb paper core located between the panel and the bottom plate, a skeleton wrapped around the honeycomb paper core is arranged between the panel and the bottom plate, and a plurality of reinforcing bars embedded in the honeycomb paper core are arranged in the skeleton , The panel and the bottom plate are respectively bonded with the honeycomb paper core, skeleton and reinforcing strip through glue. The panel and bottom p...

[0002] From the comprehensive consideration of the recycling of raw materials, the impact of raw material sources on the environment, and light weight and low transportation costs, paper composite panels are widely used, such as the Chinese utility model patent with the publication number CN201889920U, honeycomb composite panels for furniture , including a face plate, a bottom plate and a honeycomb paper core between the face plate and the bottom plate, a skeleton wrapped around the honeycomb paper core is arranged between the face plate and the bottom plate, and a plurality of reinforcing strips embedded in the honeycomb paper core are arranged in the skeleton , the panel and the bottom plate are respectively glued to the honeycomb paper core, skeleton and reinforcing strips by glue. The panel and the bottom plate of this technical scheme have no waterproof and moisture-proof protection treatment, which is easy to be affected by moisture and water, mildew occurs, and the service life is affected, and the panel and the bottom plate are fiberboards. Or melamine board, but the back of the fiberboard has a texture, which causes the surface area of ​​the two sides of the board to be unequal, and the board is warped and deformed due to the difference in expansion force after moisture absorption. The traces of glue are more obvious and the color is less, especially when it is used as a packaging material, its disadvantages are more obvious
