A blockboard produced by soybean protein glue and its process method

Abstract

The invention relates to a core board produced with soy protein glue and a technique of production, and belongs to the technical field of wood board production. A first soy protein glue layer is arranged between board cores; the board cores and the first soy protein glue layer are combined into a combined center board of board cores and first soy protein glue layer; a second soy protein glue layer is arranged between the top of the combined center board and a white blank layer; the other side of the white blank layer is connected with a first veneer layer; a third soy protein glue layer is arranged between the bottom of the combined center board and the second veneer layer. Compared to solid wood, the core board and the technique of production have the advantages that resources are saved, the appearance is more attractive and elegant, compression ratio is higher than that of a common multi-ply board, the core structure is more compact, compactness is higher, nail gripping force is larger, and the core board has high bending resistance and compressive strength; the core board has low water content and is free of expansion, shrinking and deformation; the soy protein glue used as binder has low volatility and never fails; the core board produced has good hot water tolerance and completely meets the requirements of national standard for type-II plywood.

Description

technical field [0001] The invention relates to a blockboard produced by using soybean protein glue and a process method, belonging to the technical field of woodboard production. Background technique [0002] With the rapid development of my country's economy since the 1980s, especially the rapid rise of my country's real estate industry, it has almost reached the point where there is no house without decoration. Formaldehyde, phenolic wood boards and their furniture have entered the room in large quantities due to decoration. Environment, benzene, aldehyde serious damage to people's physical and mental health problems are also significantly presented. [0003] In the production process of blockboard, logs need to be rotated and cut into veneers, and then reassembled into boards. In order to reassemble these veneers, adhesives must be used. At present, the core ingredients and main raw materials of traditional adhesives are formaldehyde, Phenolic, phenol, xylene, etc., thes...

Problems solved by technology

[0003] In the production process of blockboard, logs need to be rotated and cut into veneers, and then reassembled into boards. In order to reassemble these veneers, adhesives must be used. At present, the core ingredients and main raw materials of traditional adhesives are formaldehyde, Phenolic, phenol, xylene, etc., these chemical raw materials will cause serious harm to the human body, which is the Achilles heel of the current wood-based panels
