Abstract
The present invention relates to one kind of five-layer thick-core wooden floor board and its making process. The five-layer thick-core wooden floor board includes one surface wood layer, one gummed sheet layer, one core layer, one other gummed sheet layer and one back layer adhered together successively. The making process of the five-layer thick-core wooden floor board includes the following steps: making surface wood board, making core layer board, making gummed sheet, making back board, combination and pressing, splitting and balancing, and forming. The five-layer thick-core wooden floor board of the present invention has the advantages of less deformation caused by environment temperature and humidity, reduced surface wood layer thickness resulting in saving in high quality wood, and raised adhesion strength and high stability.
Description
Technical field
The present invention relates to building and ornament materials, particularly a kind of five-layered thick core wood compound floor board and preparation method thereof.
Background technology
The solid wooden compound floor of sandwich construction is used in various places at present, because it has environmental protection, not yielding, characteristics such as appreciation effect good, long service life, price are relatively cheap, widely people accept, for the middle layer plate of saving the timber solid wooden compound floor mostly adopts fast growing wood, for example poplar, pine, China fir, Eucalyptus or density board etc., yet famous and precious hardwood is mostly adopted on the top layer of current high-grade solid wooden compound floor, for example oak, teak and walnut etc.; In order to save the use of famous and precious hardwood, it is thick that its sheet surface layer generally is no more than 5mm; When the walking layer of solid wooden compound floor both sheet surface layer is relatively thinner, middle layer plate is just thicker relatively, and middle layer plate belong to cork with the relative sheet surface layer of material, therefore in use sheet surface layer can occur coming unstuck and the wave phenomenon, especially changes in the big environment particularly outstanding in humidity.
Summary of the invention
The objective of the invention is to use the cork middle layer plate for overcoming, occurring easily coming unstuck at sheet surface layer, wave is dived thereby the five-layered thick core wood compound floor board that proposes and preparation method thereof technical scheme; This scheme is each bonding one deck thin plate of middle layer plate top and bottom, and then overcome coming unstuck and the wave phenomenon that sheet surface layer occurs easily.
Technical scheme of the present invention is: a kind of five-layered thick core wood compound floor board, gluedd joint in proper order by top layer solid wood plate, blanket glued veneer, middle layer plate, blanket glued veneer and backboard and to form; Described blanket glued veneer thickness is less than described middle layer plate thickness, and described top layer solid wood plate direction of wooden fibers is consistent with the lagging timber machine direction, and vertical mutually with described middle layer plate direction of wooden fibers.
Described top layer solid wood plate is a hard wood.
Described hard wood is oak or walnut or teak or seal eggplant wood or face cream pigeonpea or Jatoba or birch or maple or elm or Birch or hard maple wood.
Described middle layer plate, blanket glued veneer, backboard are softwoods.
Described softwood is pine or Eucalyptus or poplar or Liu An.
Described middle layer plate is made up of the identical batten splicing of thickness.
A kind of five-layered thick core wood compound floor board preparation method, the step of this preparation method is:
A. make top layer solid wood slab plate; Hard wood is sawn into the solid wood lamina, and moisture content is controlled between the 5%-14%, and S4S is behind leveling, the edging, stand-by as top layer solid wood slab plate after the sorting balance again;
B. make the middle layer plate blanket; Select softwood for use, moisture content is controlled between the 6%-12%, it is cut be processed into the identical batten of thickness, and batten connects successively and sequences to prolong width, and is stand-by as the middle layer plate blanket;
C. make the blanket glued veneer blanket; Select softwood for use, it is peeled into plates of solid wood, moisture content is controlled at 4%-12%, and is stand-by as the blanket glued veneer blanket behind leveling, the edging;
D. make the backboard blanket; Select softwood for use, it is peeled into solid wood individual layer plate, moisture content is controlled between the 4%-12%, and leveling, edging are stand-by as the backboard blanket;
E. assembly and pressing; With the blanket handled well order by top layer solid wood slab plate, blanket glued veneer blanket, middle layer plate blanket, blanket glued veneer blanket, backboard blanket, by gluing assembly successively from top to bottom, described top layer solid wood slab plate is consistent with described backboard blanket direction of wooden fibers, and vertical mutually with described middle layer plate direction of wooden fibers; Putting into the pressing machine, to be pressed into the slab of complete one stand-by;
F. burst and balance; Whole the slab branch that pressing is good is cut into the floor blank;
G. moulding; With the backboard and the top layer solid wood plate sanding of floor blank, leave tongue-and-groove and joint tongue all around along the floor.
Described hard wood is oak or walnut or teak or seal eggplant wood or face cream pigeonpea or Jatoba or birch or maple or elm or Birch or hard maple wood.
Described softwood is pine or Eucalyptus or poplar or Liu An.
Described top layer solid wood plate thickness is 0.3mm-4mm.
Described back plate thickness is 1mm-3mm.
Described blanket glued veneer thickness is less than the thickness of core layer.
The present invention is compared with prior art:
1. because top layer solid wood plate is consistent and vertical mutually with the direction of wooden fibers of middle layer plate with the lagging timber machine direction, crisscross texture structure restricts timber stress each other.
2. effectively avoid timber to change caused floor deformation because of environment temperature, humidity, detect proof through experiment, the present invention can make floor stability improve 6 to 8 times; And owing to be the blanket glued veneer layer below the dash board, eliminated effectively and used the caused dash board of single middle layer plate stress " wave ", simultaneously can reduce top layer solid wood plate thickness, save famous and precious seeds resource, because blanket glued veneer adopts the good seeds of glue performance, solved the difficult problem of bonding strength difference between cork central layer and hardwood dash board again.
Below in conjunction with drawings and Examples the present invention is made a detailed description.
