Description

Solid wooden compound floor and its manufacture method
Technical field
The present invention relates to floor and its manufacture method, more particularly to composite floor board and its manufacture method, belong to building decoration Material manufacture technical field.
Background technology
The consumption of China's forest tree resource has extremely serious waste, according to the statistics made by the departments concerned, current China's timber profit There was only 50% or so with rate, and the wood comprehensive utilization rate of developed country is general more than 80%, and the industry of industrial wood waste material Utilization rate (not including as the energy) is more than 50%.
For domestic Floor Industry, the leftover pieces after the processing of some timber, these sides can be produced in being produced on floor Corner material is mostly with the scattered state ignored by people as refuse disposal or burning.China is that have the big of more than ten00000000 populations State, wood waste quantity is extremely surprising, will be one if these timber resources that can be recycled can not effectively be used Huge waste.So, timber utilization rate is improved, the purpose for saving timber resources and environmental protection is reached, increasingly by society The concern of meeting.
According to GB/T18103-2013《Solid wooden compound floor》In definition to solid wooden compound floor:With solid wood jigsaw or list Plate(Veneer containing recombinant decorative)For panel, using solid wood jigsaw, veneer, glued board as sandwich layer or bottom, add through various combination lamination The floor of work.There it can be seen that solid wooden compound floor either multilayer or three layers, all referring to timber in thickness direction Upper process laminated combinations are formed, and laminated multi-layer combination in the direction of the width is then extremely rare.At present, for width and thickness On direction simultaneously by timber laminated combinations solid wooden compound floor research, Floor Industry it is less occur, this Novel structure Solid wooden compound floor possess more excellent dimensional stability compared with traditional solid sawn composite floor board.
To sum up, using the leftover pieces produced in timber process, a kind of new knot of excellent size stability is designed Structure solid wooden compound floor, is a very valuable research topic, can be improved while can not only saving forest tree resource Timber utilization rate, and the solid wooden compound floor of production has excellent dimensional stability.
The content of the invention
Wasted to solve the not high caused forest tree resource of current China's Floor Industry timber utilization rate, the invention discloses The solid wooden compound floor and its manufacture method of the leftover pieces manufacture new structure produced in a kind of utilization traditional floor process, The solid wooden compound floor of the new structure of manufacture method production has excellent dimensional stability.
The veneer that the solid wooden compound floor of new structure disclosed by the invention is made using natural veneer is panel, with various hard The plate that weedtree processing clout is combined into is base material, is made up of in thickness direction panel, base material two parts.Wherein, base material is in width Spending direction, totally three parts are constituted by both sides lath, splinting layer.Wherein constitute base material splinting layer in thickness direction also by three parts Composition.
Panel:Panel wood plants the wood skin being processed into for natural precious timber.Such as teak, black walnut, hickory nut.Thickness exists 1.2-4.0mm between.
Specifically, base material part is respectively in width by up of three layers:Respectively there is a lath on both sides, and centre is folder Flaggy;Wherein splinting layer is in thickness direction and by up of three layers.Two lath specifications are all the wide * length=13mm*20mm* of thick * 1220mm, splinting layer specification is the wide * length=13mm*90mm*1220mm of thickness *.Wherein, lath is solid wood, and splinting layer is solid wood and list Plate is combined.
Specifically, splinting layer sequentially consists of bottom balance layer(The thick wide * length=1.5mm*90mm*1220mm of *), core Layer(The thick wide * length=10mm*90mm*1220mm of *), surface layer balance layer(The thick wide * length=1.5mm*90mm*1220mm of *)Composition.Its In, bottom balance layer and surface layer balance layer are all made up of rotary cut venner, and sandwich layer is solid wood.
Specifically, two laths are all opening female tenon close to splinting layer side direction, and male tenon, both sides lath are opened in splinting layer both sides Combined with middle splint in the way of tongue-and-groove interlocks.
Specifically, it is hardwood that lath, bottom balance layer, sandwich layer, the wood kind of surface layer balance layer, which is made, can make same tree Plant or different wood plant combination, combined by the processing of each tailing.
Solid wooden compound floor manufacture method disclosed by the invention is selected including tailing, lath is sized, splinting layer adds The processes such as work, substrate combination, veneer, hot pressing, health, shaping, paint, packaging.
Specifically, tailing is selected:The suitable batten of specification, veneer are selected, is classified.
Specifically, lath is sized:Using many saw blade sawing machines, by the suitable lath of specification be processed into the wide * length of thick *= 13mm*20mm*2440mm, is made embryo material, control moisture content is in 8%-12%.
Specifically, splinting layer is processed:Splinting layer is made up of bottom balance layer, surface layer balance layer, sandwich layer, first by many saws Sandwich layer is set size by piece sawing machine, and it is the wide * length=10mm*90mm*1220mm of thickness * to control its size, and it can be toothed oak that sandwich layer wood, which is planted, Each wood such as wood, Eucalyptus, pine is planted, and control moisture content is in 8%-12%.Then the wide * of thick * are made using veneer guillotine in veneer Length=1.5mm*90mm*1220mm, control moisture content is in 8%-12%, and veneer can make Eucalyptus, poplar, birch etc..Then by veneer Backsizing, is melamine modified urea-formaldehyde glue using glue, is according to mass ratio:Pure glue:Flour:Curing agent=65:(15- 25):5 carry out impregnation, and glue application amount is 120-135g/ ㎡.It is last hot according to veneer-sandwich layer-veneer short grain direction assembly Pressure, using continuous hot press, meter pressure is 10-12MPa, and temperature is 95-105 DEG C, and the time is to put after the completion of 200-250s, hot pressing Put balance cylinder to balance 3.5 days, make porous media balanced and control in 7%-10%.
Specifically, substrate combination:Using slotter, to lath one-side gaining, width of rebate * depth=4mm*4mm, then 1220mm is cut into monolithic saw length direction;Joint tongue, joint tongue thickness * length are alongst outputed to interlayer using slotter =4*4mm, it is desirable to which notch is interference fitted with joint tongue;Using purl machine pressure group is carried out according to the combination of lath-splinting layer-lath Close.The use of glue is milky white adhesive, is coated in notch inwall, coating weight 30-45g/ ㎡, pressure is 2-4MPa, is cold-pressed time 3-5h.
Specifically, veneer hot pressing, edge finishing, finish coatings, inspection are carried out according to conventional solid wood composite floor board production process Test the subsequent handlings such as packaging.Wherein:
