Embodiment 1

[0007] The upper and lower surface boards 1 and 3 are cologne wood, and the middle is medium density fiberboard 2 with a thickness of 8mm. There are 6 layers of veneer between the MDF and the upper and lower surface boards. The adjacent 2nd and 3rd layers of veneers are the long and medium boards, the 4th and 6th layers of veneers are the core boards, and the 5th and 7th layers of veneers are the long and medium boards. The configuration of the 6-layer veneer between the lower surface board and the MDF is symmetrical to the configuration of the veneer between the upper surface board and the MDF. Long medium board, the inner veneer whose wood grain direction is parallel to the wood grain direction of the surface board, core board, the inner layer veneer whose wood grain direction is perpendicular to the wood grain direction of the surface board. The long middle board and core board are made of domestic hardwood, the thickness of the upper and lower surface boards is 1.6mm, and ...

Embodiment 2

[0009] The veneer in the middle is particle board or oriented strand board, its thickness is 9mm, and there are 6 layers of veneer on each side, and the 2nd, 4th, and 6th veneer between the upper surface board and MDF are long medium boards , the 3rd and 5th veneers are core boards. The configuration of the 6-layer veneer between the lower surface board and the MDF is symmetrical to the configuration of the above-mentioned 6-layer veneer between the upper surface board and the MDF. Among them, the upper and lower surface boards are tropical broad-leaved hardwoods, and the other long middle boards and core boards are domestic hardwoods. The thickness of the upper and lower surfaces is 1.6mm, and the thickness of the long middle plate and core plate is 2mm. The above-mentioned veneers are formed by gluing and pressing, and the thickness is 28mm.

Embodiment 3

[0011] The thickness of the MDF in the middle is 7mm, and there are 8 layers of veneers on each side of it. The 2nd, 3rd, 5th, 7th, and 8th layers between the upper surface board and the MDF are long medium boards. The 6th layer is the core board. The arrangement of the 8-layer veneer between the lower surface plate and the MDF is symmetrical to the arrangement of the above-mentioned 8-layer veneer between the upper surface plate and the MDF. Among them, the upper and lower surface boards are tropical broad-leaved hardwoods, and the other long middle boards and core boards are domestic hardwoods. The thickness of the upper and lower surfaces is 1.6mm, and the thickness of the long middle plate and the core plate is 1.6mm. The above-mentioned veneers are formed by gluing and pressing, and the thickness is 28mm. The adhesive is a waterproof and anti-corrosion adhesive commonly used in container bottom plates.

Abstract

A high-strength ply-board as the bottom plate of container is composed of two surface boards made of hard wood, sandwich board which is medium-density fibroboard or shaving board, and long boards between surface board and sandwich board.

Description

Technical field: [0001] The invention relates to a plywood, in particular to a high-strength composite plywood suitable for making the bottom plate of a container. Background technique: [0002] For a long time, the plywood used for the container floor has been made of tropical broad-leaved hardwood, but tropical hardwood (clone wood) resources are becoming less and less, and there is an urgent need for alternative materials. The invention patent with the patent No. 00101394.7 provides a partial replacement of tropical broad-leaved hardwoods with domestic hardwoods to make container floors, reducing the amount of tropical hardwoods used. However, the resources of hardwoods in my country are also very scarce, and the container floor The amount is getting bigger and bigger. There is an urgent need to develop container floor plywood with a wide range of resources. Bamboo, bamboo-wood hybrid and fiber-reinforced composite floor developed in recent years have not been put into u...
