Description
Technical field
The present invention relates to floor producing technology field, specifically disclose a kind of solid wood multi-layer composite floor board and preparation technology thereof
With assembly method.
Background technology
Solid wooden compound floor timber floor, with advantages such as its natural environmental-protective, abundant gentle, the beautiful texture natures of texture, is the most more come
Enter into average family manyly.Solid wooden compound floor is divided into three-layer wood composite flooring and multi-layer solid wood composite floor.Family wear
Commonly use in repairing is three-layer wood composite flooring.Three-layer wood composite flooring is to be formed by three-layer real-wood veneer crosswise lamination, its
Top layer is high-quality broadleaf specification lath edge jigsaw or view picture plank, the multiplex Xylosmae japonici of assortment, Fagus sinensis Oliv., birch, Cortex Fraxini mandshuricae etc.；Core
Layer is made up of common soft miscellaneous specification wood lath, the multiplex Masson Pine of assortment, poplar etc.；Bottom is rotary cut venner, the multiplex poplar of assortment, birch
Wood, Masson Pine, three-decker glue-line pressure forms.Multi-layer solid wood composite floor is with multi-plywood as base material, with specification hardwood
Thin slice edge jigsaw or veneer are panel, and lamination forms.Multi-layer solid wood composite floor substantially increases wood comprehensive utilization rate, especially
It is to have saved a large amount of high-quality timber, the beneficially comprehensive utilization of China's Forest Resources, can preferably promote the low-carbon (LC) of Floor Industry
Economic development, significant for the benign development promoting Floor Industry.But multi-layer solid wood composite floor complex process, raw
Product easily occurs the high problem of percent defective of the snap close unstable properties of fluting, fluting.
Summary of the invention
It is an object of the invention to overcome the defect of prior art, it is provided that a kind of solid wood multi-layer composite floor board and preparation work thereof
Skill and assembly method, the snap close stable performance of the fluting of this solid wood multi-layer composite floor board, greatly reduce the percent defective of fluting.
In order to realize object above and other purposes, the present invention is by including that techniques below scheme realizes: a kind of group
Blank technology, comprises the following steps: binded according to the mode that texture is staggered by two central layers, obtains double-deck central layer, make to
Few two described double-deck central layers；Three central layers are binded according to the mode that texture is staggered, obtains three layers of central layer, make at least
One described three layers of central layer；By the two sides of described three layers of central layer, one side with described double-deck central layer is binded respectively, and described three
Layer central layer is identical with the grain direction of the central layer that each described double-deck central layer binds position mutually.
Invention additionally discloses the preparation technology of a kind of solid wood multi-layer composite floor board, comprise the following steps: the preparation of central layer: choosing
Select that thickness is uniform, thickness is moderate, and zero defect, solid wood central layer without fracture, and carry out assembly, group by splicing machine hot melt wire
Become the size needed for base material；The preparation of base material: be slab according to assembly method assembly as described above by described central layer, it is desirable to
Put neat during assembly up and down；Cold moudling: the described slab completed by assembly carries out pre-molding by cold press；Hot pressing glue
