Abstract
The invention discloses plywood for container flooring, which is formed by hot pressing and gluing a plurality of veneers. The plywood comprises an upper surface course, a lower surface course and a middle layer, wherein the veneer comprises wood veneer and bamboo veneer; the upper surface course and the lower surface course respectively comprise continuous three layers of grain wood veneers, namely, one layer of cross striation veneer, and one to two layers of grain bamboo veneers from the outside to the inside in turn; and the middle layer consists of a grain veneer and a cross striation veneer, including three or more layers of continuously laminated grain veneers. The plywood for the container flooring relives the problem of strained forest resources through composition of bamboo and wood by using bamboo resources, reasonably designs the structure of the bamboo and wood composite container flooring, eliminates the defect of uneven surface of the container flooring caused by the bamboo characteristics, better plays the characteristic of strong bending resistance of the bamboo materials, fulfils the requirement on strength of the container flooring, and reduces the production cost of the container.
Description
Technical field
The present invention relates to a kind of glued board, relate in particular to a kind of composite board for bottom board of container.
Background technology
The continuous aggravation in short supply of the present global forest reserves; Particularly high-quality timber resources constantly minimizings such as the higher clone of intensity wood and hardwood; The cost of raw material of container bottom board is also in continuous rising, and the utilization that has had increasing people that sight is transferred to bamboo timber resource in the container bottom board industry comes up.Along with people's is to the continuous exploration and the research of bamboo wood characteristic, and in recent years, the bamboo wood composite more and more receives numerous personages' in the industry concern.
Bamboo wood has vertical tension and the high characteristics of bending strength; Through using the bamboo wood composite; Can be good at increasing the intensity of container bottom board, but, certainly exist bigger slit between the bamboo chip simultaneously because bamboo wood need be processed bamboo chip with bamboo when using conspires to create bamboo curtain splint and use.In the production process of container bottom board; In order to bring into play the high characteristics of bamboo wood bending strength, producer's custom is put in bamboo wood near container bottom board surperficial so that better bring into play the resistance to tension of bamboo curtain splint, guarantees the intensity of container bottom board; But because the radian that slit between bamboo curtain splint and bamboo chip self exist; Cause bad phenomenon such as container bottom board surface irregularity easily, panel is passed through by sand easily when carrying out sanding, and in use panel surface is prone to defectives such as cracking; This not only has a strong impact on the outward appearance of container bottom board, also causes the instability of container bottom board self intensity.Also there is the researcher bamboo curtain splint veneer to be put in the mid portion of container bottom board; Though eliminated the superficial defects that bring in the slit between bamboo chip like this; But fail to get hold of the gummed characteristic of bamboo; Make that the gummed between the bamboo wood is relatively poor relatively, the sandwich layer position is sheared destruction easily, unstable properties in actual production and use.
At present; Some patents relevant with bamboo wood composite container baseboard are disclosed in the patent gazette; But these patents more are conceived to how to utilize the angle of bamboo matter resource, all fail from eliminate in essence defective that the bamboo wood characteristic brings, better bring into play the bamboo wood self performance, stablize the performance of bamboo wood composite container baseboard.
Summary of the invention
The present invention is intended to overcome the deficiency of prior art; A kind of composite board for bottom board of container of composite bamboo-timber structure is provided; Utilize bamboo matter resource to alleviate the nervous problem of the forest reserves, the structure of bamboo wood composite container baseboard is reasonably designed, eliminate the defective of the container bottom board surface irregularity that the bamboo wood characteristic brings; Better bring into play the strong characteristics of bamboo wood bending resistance, satisfy the requirement of strength of container bottom board simultaneously.
For achieving the above object, the present invention adopts following technical scheme:
A kind of composite board for bottom board of container is provided; Form by the hot-press gluing of multilayer veneer; It comprises upper layer, down surface layer and intermediate layer, and said veneer comprises veneer and bamboo veneer, and said upper layer and said time surface layer ecto-entad are followed successively by continuous 3 layers of rift grain veneer, 1 layer of band veneer, 1-2 layer rift grain bamboo curtain splint veneer; Said intermediate layer is made up of rift grain veneer and face crossing, and this intermediate layer comprises and haves three layers or the rift grain veneer of continuous stratification more than 3 layers.
In the present invention, said intermediate layer and said upper layer, the said adjacent veneer of surface layer down are face crossing.
The seeds of in the present invention, making said veneer in clone, Marasse, leatherleaf Pometia spp, birch, beech, peach blossom core, red Lan Ren, poplar, eucalyptus, pine, pinus caribaea, larch, fish-scale floss, wet-land pine tree, masson pine, pine, dragon spruce, the fir any one or more than one.
In the present invention, the said upper layer and/or the veneer of outermost layer veneer for crossing of surface layer down through the resin impregnation process.
In the present invention, the outermost layer veneer surfaces coated of said upper layer and/or said down surface layer is decorated with one deck functional resin or posts at least one deck Tetefol or post one deck resin immersion non-woven fabrics at least.
In the present invention, said covering with paint functional resin layer or Tetefol layer or resin immersion non-woven fabrics layer are provided with wood grain or asperities embossment.
In the present invention, said veneer is gone out to meet the specification of instructions for use or is adopted the less veneer of specification to be spliced into desired specification in identical grain direction by the direct rotary-cut of log.
In the present invention, the method for the less veneer of splicing specification comprises splicing, finger, butt joint.
Compared with prior art, beneficial effect of the present invention is:
1, composite board for bottom board of container of the present invention; Reduce the demand of container bottom board through the compound characteristic of bamboo material of utilizing of bamboo wood to high-quality timber; It is in short supply to the raw-material impact of container bottom board to alleviate world forest resources, reduces the production cost of container bottom board;
2, pass through reasonable structural design; Bamboo wood is positioned over comparatively reasonably position; Can bring into play the anti-bending strength of bamboo wood preferably; Blemish during the uneven and sanding of the plate surface that also can avoid the bamboo curtain splint slit to cause has improved the intensity of container bottom board, guarantees the quality of container bottom board.
