The invention provides a multilayer board, a producing method for the multilayer board and a lancing device for a veneer of the multilayer board. According to the anti-deformation multilayer board and the producing method, a lance is formed in the veneer; the structural relation of the lance can provide a deformation space for the veneer when the veneer is deformed, so that overall deformation of the veneer is prevented; at the same time, the lancing device for the veneer of the multilayer board can process the lance with an anti-deformation structure on the veneer quickly, and the overall deformation of the veneer is prevented. According to the provided multilayer board, the technical effects of being free from deformation, layering, bubbling and seaming and high in nail-holding power can be achieved.

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.

The invention relates to a three-layer coextruded PVC (polyvinylchloride) wood-plastic composite foam board and a preparation method of the three-layer coextruded PVC wood-plastic composite foam board. The wood-plastic composite foam board is of an ABA structure; an outer layer, namely an A layer, adopts polyvinyl chloride, a filler, an impact modifier, a lubricating agent, a composite stabilizer, a coupling agent, a processing agent and a polyvinyl chloride recycled material as raw materials, and an inner layer, namely a B layer, adopts the polyvinyl chloride, wood fiber powder, the filler, a foaming agent, an enhancer, a foaming regulator, the impact modifier, the lubricating agent, the composite stabilizer and a plate recycled material as raw materials. The three-layer coextruded wood-plastic composite foam board is formed by a main machine and an auxiliary machine in a coextrusion molding manner after mixing at high temperature and cooling. The three-layer coextruded PVC wood-plastic composite foam board has the processing property similar with that of wood, is anti-flaming and does not release formaldehyde, so that the three-layer coextruded PVC wood-plastic composite foam board becomes an ideal material for replacing the wood, can be used as building templates, cabinet boards and the like.

The invention discloses a polyvinyl chloride co-extrusion wood-plastic plate and a preparation method thereof. The co-extrusion wood-plastic plate comprises a core layer and surface layers located on the upper surface and the lower surface of the core layer. The core layer is prepared from PVC resin, a foaming agent, a wood-plastic material and auxiliaries. The surface layers are prepared from PVC resin. Due to the fact that the wood-plastic material is used in the core layer, the use amount and the raw material cost of PVC materials can be reduced, recycling can be achieved after the service life is reached, and the polyvinyl chloride co-extrusion wood-plastic plate is very environmentally friendly. The polyvinyl chloride co-extrusion wood-plastic plate has the strength and the finish degree of the surface of a co-extrusion foam plate and can be directly applied to the advertising industry, and printing can be directly conducted on the surface of the polyvinyl chloride co-extrusion wood-plastic plate. The polyvinyl chloride co-extrusion wood-plastic plate has the characteristics of a wood-plastic plate, nail holding power is better than that of the co-extrusion plate, and the polyvinyl chloride co-extrusion wood-plastic plate is widely used in the furniture industry, the decoration industry and the bathroom industry.
