Abstract
The utility model discloses a highly shearing-resistant container bottom board with a special structural design. The highly shearing-resistant container bottom board is characterized by comprising the following structures: a layer of surface-back-layer longitudinal texture single board (1), two layers A of longitudinal-texture wooden single boards (2), and two layers B of longitudinal-texture wooden single boards (3) symmetrical from external part to internal part; then a layer B of longitudinal-texture wooden single board (3) paved between two layers of transverse texture single boards (4) towards the inside; and five layers of B longitudinal-texture wooden single boards (3) at the middle part; and a layer of phenolic aldehyde impregnated material (5) is arranged on the outermost layer, wherein the phenolic aldehyde impregnated material (5) is impregnated paper, or impregnated non-woven fabrics, or impregnated glass fabric. 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
The utility model relates to a kind of high shearing resistance container bottom board, with raw material such as Australian pine, Eucalyptus and hardwood, make container bottom board, belong 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, the container transportation development is 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 substitution material of seeking clone and A Bidong is very urgent, and timber and the quick-growing plantation material through the forest authentication 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 vertically arrangement, outwards be criss-cross arrangement again, these arrange to container bottom board stressed big, span is short not too suitable, because container bottom board is under the stressing conditions of short span, the intermediate layer can be subjected to bigger shearing force, and it also is the reliability of judging container bottom board accordingly that the world rents case association (IICL) 7.26 tons of dolly van tests commonly used.This patent is exactly at 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 utility model provides a kind of high shearing resistance container bottom board.Its objective is that Wooden veneers such as utilizing beech, birch, clone is the table backing layer, the sandwich layer veneer mostly is quick-growing plantation materials such as Eucalyptus, Australian pine, add the tropical hard wood veneer that a spot 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.
Adopt 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 complete vertically arrangement, and adopt the high Australian pine of vertical shear behavior, 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 utility model: its structure be from outside to inside up and down symmetry establish: one deck table backing layer is with vertical texture veneer, the vertical texture Wooden veneer of two-layer A, the vertical texture Wooden veneer of two-layer B; Be two-layer cross grain Wooden veneer inwardly again, the vertical texture Wooden veneer of therebetween one deck B of this two-layer cross grain Wooden veneer, middle five layers are the vertical texture Wooden veneer of B; Adopt one deck phenolic impregnated material at outermost layer, this phenolic impregnated material is impregnated paper, or immersion non-woven fabrics, or dipping glass cloth.
Advantage of the present utility model: can effectively utilize China and timber all over the world, various softwoods, broadleaf timber as wildwood and artificial fast-growing woods, with the compound use of these materials, through science design and reasonable combination, both can solve tropical hard wood difficulty in short supply in the world wide, can solve the technical barrier of the novel base plate of high shearing resistance of producing to meet the requirement of trans-container industrial technology in enormous quantities again.
The present invention as the table backing layer, is composited beautiful texture, flawless high-quality veneer again by the Wooden veneer with the speed life.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, every performance indications 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.
