Description
Technical field
The present invention relates to floor and manufacture method thereof, particularly relate to composite floor board and manufacture method thereof, belong to building and ornament materials manufacturing technology field.
Background technology
The consumption of China's forest tree resource also exists very serious waste, according to the statistics made by the departments concerned, current China timber utilization rate only has about 50%, and the wood comprehensive utilization rate of developed country is generally more than 80%, and the industrial utilization rate of industrial wood waste material (not comprising as the energy) is more than 50%.
For domestic Floor Industry, can produce the leftover pieces after the processing of some timber in floor produces, these leftover pieces are used as refuse disposal or burning mainly with the scattered state ignored by people greatly.China is the big country having tens00000000 populations, and wood waste quantity is extremely surprising, if these timber resources that can recycle can not effectively be used, will be a huge waste.So, improve timber utilization rate, reach the object of saving timber resources and protection of the environment, more and more receive the concern of society.
Definition according to solid wooden compound floor in GB/T18103-2013 " solid wooden compound floor ": with solid wood jigsaw or veneer (containing recombinant decorative veneer) for panel, with solid wood jigsaw, veneer, veneer for sandwich layer or bottom, through the floor of various combination lamination process.Therefrom can find out, no matter solid wooden compound floor is multilayer or three layers, and all refer to that timber forms through laminated combinations in a thickness direction, laminated multi-layer combination is in the direction of the width then extremely rare.At present, on width and thickness direction simultaneously by the research of the solid wooden compound floor of timber laminated combinations, in the less appearance of Floor Industry, the solid wooden compound floor of this Novel structure possesses more excellent dimensional stability compared with traditional solid sawn composite floor board.
To sum up, utilize the leftover pieces produced in timber process, design a kind of new structure solid wooden compound floor of excellent size stability, it is a very valuable research topic, timber utilization rate can be improved while not only forest tree resource can being saved, and the solid wooden compound floor produced has excellent dimensional stability.
Summary of the invention
In order to solve the not high forest tree resource waste caused of current China Floor Industry timber utilization rate, the invention discloses a kind of solid wooden compound floor and the manufacture method thereof that utilize the leftover pieces produced in the process of traditional floor to manufacture new structure, the solid wooden compound floor of the new structure that this manufacture method is produced has excellent dimensional stability.
The veneer that the solid wooden compound floor of new structure disclosed by the invention is made with natural veneer is for panel, and the plate be combined into various hardwood processing clout, for base material, is made up of panel, base material two parts at thickness direction.Wherein, base material width by both sides lath, splinting layer totally three parts form.The splinting layer wherein forming base material is also made up of three parts at thickness direction.
Panel: the wooden skin be processed into for natural precious timber planted by panel wood.As teak, black walnut, hickory nut etc.Thickness is between 1.2-4.0mm.
Particularly, base material part forms by three layers at width, and respectively: respectively there is a lath on both sides, centre is splinting layer; Wherein splinting layer forms by three layers again at thickness direction.Two lath specifications are all the wide * length=13mm*20mm*1220mm of thick *, and splinting layer specification is the wide * length=13mm*90mm*1220mm of thick *.Wherein, lath is solid wood, and splinting layer is that solid wood and veneer combine.
Particularly, splinting layer is followed successively by bottom balance layer (the wide * length=1.5mm*90mm*1220mm of thick *) from bottom to up, sandwich layer (the wide * length=10mm*90mm*1220mm of thick *), and surface layer balance layer (the wide * length=1.5mm*90mm*1220mm of thick *) forms.Wherein, bottom balance layer and surface layer balance layer are all made up of rotary cut venner, and sandwich layer is solid wood.
Particularly, two laths are all driving female tenon near direction, splinting layer side, and public tenon is driven in splinting layer both sides, and the mode that both sides lath interlocks with tongue-and-groove with middle splint is combined.
Particularly, make lath, bottom balance layer, sandwich layer, surface layer balance layer wood kind be hardwood, same seeds can be made, also can be that combination planted by different wood, process combination by each tailing.
Solid wooden compound floor manufacture method disclosed by the invention comprises that tailing is selected, the processing of lath sizing, splinting layer, substrate combination, veneer, hot pressing, health, shaping, the operation such as paint, packaging.
Particularly, tailing is selected: select the suitable batten of specification, veneer, classify.
Particularly, lath sizing: use many saw blade sawings machine, is processed into the wide * length=13mm*20mm*2440mm of thick *, makes stock by lath suitable for specification, controls moisture content at 8%-12%.
