Problems solved by technology

The cork in the above technical solution is also a non-renewable resource, and the cork production area is relatively concentrated, and the world's total annual output is only 350,000 tons. Correspondingly, the price of cork on the market is much higher than that of ordinary boards. Therefore, the above technical solution high cost

Abstract

The invention discloses a metal surface plant fiber composite plate, which comprises a first surface layer and a second surface layer, wherein a middle layer is arranged between the first surface layer and the second surface layer in a bonding way, the first surface layer and the second surface layer are metal plates or metal alloy plates, and the middle layer is a no-glue plywood pressed by natural fiber and synthesized fiber felt. The invention also discloses a rail train floor and a production method of the metal surface plant fiber composite plate. The metal surface plant fiber composite plate has the advantages that the self weight is light, the mechanical performance, the shock resistance, the sound-absorbing noise reduction and the heat insulation are excellent, the production method is simple, and the operation is easy. The metal surface plant fiber composite plate is used for the rail train floor, the long-time high load can be borne, and the recycling and reusing can also be realized.

Description

technical field [0001] The invention relates to the field of plates, in particular to a metal-faced plant fiber composite board and a production method thereof, and also relates to a rail train floor manufactured by using the metal-faced plant fiber composite board. Background technique [0002] Sheet products have a flat shape, a large aspect ratio, and a large surface area per unit volume. Boards were originally solid wood boards, which were used to make furniture or other living facilities. Nowadays, with the development of science and technology, the definition of boards is very broad. There are boards of different materials in furniture manufacturing, construction, and processing industries. Wooden boards are light in weight, especially some man-made boards such as plywood, particle board, and fiberboard, which have stronger functionality and higher mechanical strength than solid wood boards. However, its main component, solid wood, grows slowly and is a non-renewable ...
