The maximal collapsing force of 254mm short span is more than 9300N. The highly shearing-resistant container bottom board is structured in that the upper and lower layers are made of longitudinal single boards with attractive color and textures; 2-4 layers of longitudinal texture signal boards with high mechanical properties are symmetrically arranged towards the inside; transverse texture single boards and longitudinal texture single boards are paved at intervals towards the inside; and 5-9 layers of longitudinal texture single boards are arranged on the middlemost part; and a layer of phenolic aldehyde impregnated materials is arranged on the outermost layer. The highly shearing-resistant container bottom board has the advantages of high shearing resistance, and attractive surface layer color, material resources are sustainable, and various performance indexes of the highly shearing-resistant container bottom board satisfy the technical requirements of the international container industry.
Description
Technical field
What the present invention relates to is a kind of high shearing resistance container bottom board and manufacture method thereof, with raw material such as Australian pine, Eucalyptus and hardwood, makes container bottom board, belongs to the wood-based plate manufacturing technology field in the timber industry.
Background technology
In the modern logistics container with load and unload fast, turnover, convenient transportation safety and being used by more and more, accelerate along with the process of global economic integration, Container Transport already develops very fast, the demand of container also increases severely with day.The main loaded area of container is wooden base plate, requires its base plate to have higher mechanical property, presentation quality, impact resistance and ageing-resistant performance.For a long time, almost all rely on the thick multiplyplywood that the hard broadleaf clone (Keruing) that grows in the tropical rain forest and A Bidong (Apitong) make and make base plate.Because the growth cycle of such seeds is very long, generally all need more than 50 years, the alternative materials of seeking clone and A Bidong is very urgent, and timber and the quick-growing plantation material through Forest Certification becomes first-selection for this reason.
During existing container bottom board is produced, the crisscross arrangement of the normal employing of intermediate layer Wooden veneer; Or middle three layers of longitudinal arrangement, outwards be again criss-cross arrangement, these arrange to container bottom board stressed large, span is short not too suitable, because container bottom board is under the stressing conditions of short span, the intermediate layer can be subject to larger shearing force, and it also is the reliability of judging accordingly container bottom board that the world rents case association (IICL) 7.26 tons of dolly van tests commonly used.This patent is exactly for this, improves the short span shear strength of container bottom board, guarantees to produce the container bottom board reliable in quality.
Summary of the invention
The purpose of this invention is to provide a kind of high shearing resistance container bottom board and manufacture method.Its objective is that Wooden veneers such as utilizing beech, birch, clone is the table backing layer, the sandwich layer veneer mostly is the quick-growing plantation materials such as Eucalyptus, Australian pine, add the tropical hard wood veneer that a small amount of intensity is high, make the surface layer with color and luster and beautiful texture, and satisfy the base plate of container bottom board performance requirement.
The present invention adopts some color and lusters and beautiful texture and flawless Wooden veneer as surface material, sandwich layer adopts the artificial forest wood that can fell in a large number, adopting middle five layers of Wooden veneer above is full longitudinal arrangement, and the high Australian pine of employing longitudinal shear resistance performance, the shear strength of base plate is improved greatly, and 254mm is short to stride maximal destruction power greater than 9300N.The container bottom board that makes like this has beautiful texture and color and luster, and the shear strength of base plate is higher than traditional clone or A Bidong base plate, can satisfy the permanent needs that use of container bottom board.
Technical solution of the present invention: its structure be from outside to inside up and down symmetry establish: one deck table backing layer is with vertical texture high-quality veneer, inwardly be two-layer vertical texture Wooden veneer (or two-layer vertical texture Wooden veneer, inside again is two-layer vertical texture Wooden veneer); Again inwardly for the cross grain Wooden veneer and vertically the texture Wooden veneer be staggered, middlely be vertical texture Wooden veneer more than five layers.
A kind of manufacture method of high shearing resistance container bottom board, its processing step divides:
A, Wooden veneer sorting and arrangement, Wooden veneer moisture content≤10% is selected without the veneer of joint, zero defect, beautiful texture as the table backing layer, according to the required two-sided phenol glue that is coated with, glue-spread 300～400g/m
2, add 10～15% filler and a small amount of pesticides such as flour in the glue, then 70 ℃ of dry 10min of ageing 40～70min or low temperature;
B, assembly with multiple veneer assembly, are 130～150 ℃ in temperature, and maximum pressure is to carry out hot pressing under the condition of 1.8～2.5MPa, keeps 30～40 minutes, then divides three sections step-downs, steam discharge, release.
Advantage of the present invention: can effectively utilize China and timber all over the world, various softwoods, broadleaf timber such as wildwood and artificial fast-growing woods, these Material claddings are used, through science design and reasonable combination, both can solve tropical hard wood difficulty in short supply in the world wide, can solve again the technical barrier of the high shearing resistance Novel bottom plate of producing to meet the requirement of trans-container industrial technology in enormous quantities.
The present invention as the table backing layer, is composited beautiful texture, flawless high-quality veneer again by the Wooden veneer with fast-growing.All should add pesticide in the used glue, uniformly penetrating is in the layers of material of container bottom board when hot pressing to make it, and base plate has long-acting insect protected performance like this; Core material and surface material are combined into slab, make container bottom board through hot-press gluing again, the property indices such as its intensity, elastic modelling quantity, surface quality and short span are anti-shearing can both meet the specification requirement of trans-container industry fully.
