Abstract
Disclosed is laminated plywood for bottom plates of bamboo and wood composite containers. A plurality of veneers are combined, pre-pressed and glued in a hot pressing manner to form the laminated plywood, and the laminated plywood sequentially comprises an upper surface layer, a veneer layer, a middle layer, another veneer layer and a lower surface layer. The laminated plywood is characterized in that the veneers are wood veneers and/or bamboo curtain veneer, and bond paper layers are further coated on surfaces of the veneers of the upper surface layer and/or the lower surface layer. A lay-up manufacturing method of production line operation is adopted for the laminated plywood for the bottom plates of the bamboo and wood composite containers, the problem that layers of manual lay-up are easy to be confused is avoided, use quantity of adhesive is reduced, production efficiency is high, production cost is lowered, defects of uneven surfaces of bottom plates of containers due to characteristics of bamboo are overcome, bending resistance of the bamboo is realized effectively, and the requirement on the quality of the bottom plates of the containers is met assuredly.
Description
Technical field
The present invention relates to a kind of bamboo wood composite container baseboard and use glued board, relate in particular to a kind of bamboo wood composite container baseboard and use film coating plywood.
Background technology
The main loading end of container is a base plate, and container manufacture requires base plate to have very high mechanical property, presentation quality, impact resistance and ageing-resistant performance.The wearability and the stain resistance of container timber apron are relatively poor, need face veneer is covered with paint, lacquer, colour wash, etc., and need with high-quality timber as dash board in the production.General employing high density rigid broadleaf is a primary raw material, and such seeds have seriously influenced the raw material supply of container bottom board because the production cycle is long, and resource constantly reduces.The insider is increasing to be transferred to timber floor on the compound film coating plywood of bamboo wood; Along with people's is utilized resourceful homemade bamboo wood resource to produce bamboo wood composite container baseboard and is used film coating plywood the continuous exploration and the research of bamboo wood characteristic and bamboo timber resource, has great realistic significance.
Bamboo wood has tension and the high characteristics of bending strength, the compound intensity that can be good at increasing container bottom board of bamboo wood; Because the big radian that exists with bamboo wood self in the slit that in the braiding process, produces of bamboo curtain splint, cause easily uneven whole, defective such as relief is big, the present invention all is emitted on position among the veneer with bamboo curtain splint, with the deficiency of the defective of alleviation bamboo curtain splint own.Single or double at glued board attaches impregnated bond paper, can strengthen the wearability and the stain resistance of glued board, need not the user face veneer is covered with paint, lacquer, colour wash, etc. again.Some bamboo wood composite container baseboards are used film coating plywood at present, and its assemble pattern is still continued to use the assemble pattern of timber floor; The present invention adopts the manufacturing approach of production line assembly; Avoided the easy entanglement of assembly level, the glue-spread of different levels veneer thickness is uncontrollable, and the veneer that book size is little is distributed to each layer structure; Workman's operating technology is required height, the defective that production efficiency is low; Improve the utilization rate and the production efficiency of material, reduced production cost, also guaranteed the stability of product quality simultaneously.
Summary of the invention
The object of the present invention is to provide that a kind of structure is novel, steady quality, the low bamboo wood composite container baseboard that satisfies impact resistance, wearability, stain resistance and the requirement of strength of container bottom board simultaneously of production cost use film coating plywood.Through adopting composite bamboo-timber structure, top layer to attach bond paper etc.; The compound overlay film base plate of the bamboo that obtains having wood, reach economical with materials, simplify the assembly method, reduce adhesive use, overcome the bamboo wood characteristic and bring the defective of container bottom board surface irregularity, bring into play the strong characteristics of bamboo wood bending resistance better.
For achieving the above object, the present invention adopts following technical scheme:
A kind of bamboo wood composite container baseboard is used film coating plywood; Form through combination, precompressed, hot-press gluing by the multilayer veneer; Comprise upper layer, ply, intermediate layer, ply, following surface layer successively; Said veneer is veneer and/or bamboo curtain splint veneer, and the outermost layer veneer surface of said upper layer and/or following surface layer has also posted the glued membrane ply of paper.
Bamboo wood composite container baseboard of the present invention is used film coating plywood; Said upper layer and following surface layer are the veneer plywood of 3 layers of vertical texture; The plywood of said intermediate layer for being made up of the vertical bamboo curtain splint veneer plate behind the veneer of 4 layers of vertical texture and the 1 layer of impregnation that is clipped in the center, ply are that cross grain is crossed vertical bamboo curtain splint veneer behind bakelite veneer and the impregnation and replaced lamination and form.
Bamboo wood composite container baseboard of the present invention is used film coating plywood, described upper layer, intermediate layer, down surface layer adjacent veneer be the veneer of cross grain.
Bamboo wood composite container baseboard of the present invention is used film coating plywood, and the seeds of said veneer are that clone, A Bidong, Marasse, beech, You Jiali, birch, poplar, Eucalyptus, spoke thank to one or more in pine, larch, the masson pine.
Bamboo wood composite container baseboard of the present invention is used film coating plywood, and the veneer level of said glued board is 21 layers, and wherein said bamboo curtain splint veneer is 5 layers.
Bamboo wood composite container baseboard of the present invention is used film coating plywood, and the less veneer of said veneer central layer available sizes carries out mitered, toe joint becomes required specification on identical texture;
Bamboo wood composite container baseboard of the present invention is used film coating plywood, and said glued membrane ply of paper is that phenolic resin glue flooded, through suitably dry bond paper.
Bamboo wood composite container baseboard of the present invention is used film coating plywood, and said glued membrane ply of paper is provided with wood grain or asperity embossment.
Among the present invention, the joining method of the veneer that book size is less is:
1. veneer is ground to the gradient of 6-10 degree on the bevel grinding machine, coats phenolic resin glue, two gradient overlap joints after hot-press gluing on the bar shaped press, cut into the veneer of required specification.
2. veneer is cut into the zigzag that tooth depth is 50mm on the profile of tooth cutter, dock.
Beneficial effect:
1. a kind of bamboo wood composite container baseboard of the present invention is used film coating plywood, uses the manufacturing approach of pipelining assembly, has avoided the phenomenon of the easy entanglement of manual assembly level; Reduced the use of adhesive; Production efficiency is high, has reduced production cost, has overcome the blemish of bamboo wood characteristic to the container bottom board surface irregularity; Bring into play the anti-bending strength of bamboo wood preferably, guaranteed the quality requirement of container bottom board.
2. compound through bamboo wood, the container bottom board that surface coating is produced has utilized abundant homemade bamboo timber resource, has reduced the raw material supply demand of the shortage of world forest resources to container bottom board production significantly, has also reduced production cost simultaneously.
3. a kind of bamboo wood composite container baseboard of the present invention is used film coating plywood; Solved container bottom board presentation quality, impact resistance, resistance to ag(e)ing, wearability and stain resistance relatively poor, need to cover with paint, lacquer, colour wash, etc. to face veneer, and need in producing with the many problems of high-quality timber.
