Description
Technical field
The invention belongs to timber floor manufacturing technology field, relate to Compossite solid-wood floor plate, particularly relate to a kind of European spruce three-layer wood composite flooring and preparation technology thereof.
Background technology
Along with the drastically minimizing of whole world wildwood resource, wood working industry occurs in that the phenomenon of raw material worsening shortages.China's timber resources is the deficientest, and the high-quality famous and precious hardwood resource that especially floor surface is used relies primarily on import, and current timber export country gradually starts to reduce the export quotas of log resource so that sheet surface layer raw materials used day is becoming tight.Timber floor is as a kind of important ornament materials of interior decoration, market demand is increasing, solid wooden compound floor typically uses the famous and precious hardwood seeds of 3～4mm thickness hard woods as top layer, used by intermediate layer, bottom, cork veneer mostly is the fast growing woods such as PiceameyeriRehd. Et Wils., Pinus sylvestnis var. mongolica Litv., poplar, Eucalyptus, three layers of wooden soft or hard collocation, texture is crisscross, and stability is greatly improved relative to traditional solid sawn floor.Further, solid wooden compound floor resin added in process of manufacture is low, the feature of environmental protection good, is increasingly favored by market, is the fastest solid wood class flooring product of development in recent years.Wherein, three-layer wood composite flooring, due to its excellent stability and the feature of environmental protection, is favored by increasing consumer.
European spruce originates in the north, Europe and middle part, for one of Northern Europe Major Tree Species Planted, Pinaceae, Picea, density about 440kg/m3, logical straight, the beautiful texture of timber, footpath level is big, and machining is dried easily, without recessive defect；Electric pole, sleeper, building, bridge material can be made, make musical instrument, aerodone etc., and be the raw material of papermaking.European spruce is because of its price material benefit, and sawing is superior in quality, is used as the sandwich layer part of three-layer wood composite flooring by a large amount of imports.The Chinese patent of Publication No. CN1663762A discloses the technique utilizing pure poplar to make solid wooden floor board, can preferably overcome the defect that poplar matter is soft, but its course of processing also needs to carry out computer fill in colors on a sketch and emulate, the bleaching of board using poplar board, the operation such as dyeing, process is complicated and wayward, relatively costly, it is not necessary to preferably to carry out in industrialized production.
European spruce is used as the dash board of three-layer wood composite flooring, the most not yet has similar techniques scheme open.Three-layer wood composite flooring using European spruce thin plate as dash board disclosed in this invention, can greatly reduce again production cost in the mechanical property ensureing floor simultaneously；Owing to European spruce material is softer, density is relatively low, coordinates floor surface to use stiffened painting technology, can improve hardness and the wearability on floor.
Summary of the invention
It is an object of the present invention to the three-layer wood composite flooring disclosing a kind of European spruce thin plate as dash board.
A kind of European spruce three-layer wood composite flooring, is formed by the glued assembly of dash board (2), central layer (3) and base plate (4), wherein, is coated with paint paint film stiffening layer (1) on described dash board (2), and its thickness is 0.15～0.20mm, and hardness reaches 2H；Described dash board (2) is spelled by European spruce thin plate side and is formed, and thickness is 2.0～4.0mm, and moisture content is 5.5～8.0%；Described central layer (3) is European spruce lath, and width is 20～50mm, and thickness is 7～9mm, and moisture content is 6～10%；Described base plate (4) is Pinus sylvestnis var. mongolica Litv. rotary cut venner, and thickness is 1～2mm, and moisture content is 5.0～6.5%.
In the more excellent disclosed example of the present invention, described dash board (2) is spelled by European spruce thin plate side and is formed, and the gap between plate is not more than 0.5mm.
In the more excellent disclosed example of the present invention, described floor thick-ness is 10～15mm.
Another object of the present invention is, disclose the preparation technology producing above-mentioned European spruce three-layer wood composite flooring, using European spruce thin plate as dash board, European spruce lath is as central layer, Pinus sylvestnis var. mongolica Litv. veneer is as base plate, painted by the thick product surface roller coat stiffened again obtained by the operations such as gluing, assembly, hot-press gluing, cooling, sanding, final prepared European spruce three-layer wood composite flooring.
A kind of preparation technology of European spruce three-layer wood composite flooring, comprise the steps: European spruce thin plate as dash board, European spruce lath as central layer and Pinus sylvestnis var. mongolica Litv. veneer as base plate, gluing, then floor surface roller coat stiffened base oil paint again after assembly, hot-press gluing, cooling, health preserving, subdivision, sanding.
In the more excellent disclosed example of the present invention, described European spruce thin plate, is that European spruce is sawed into the plate that thickness is 2.0～4.0mm, and moisture content is 5.5～8.0%, spells its side as dash board, and the gap between plate is not more than 0.5mm.
In the more excellent disclosed example of the present invention, described European spruce lath, width is 20～50mm, and thickness is 7～9mm, and moisture content is 6～10%.
In the more excellent disclosed example of the present invention, described Pinus sylvestnis var. mongolica Litv. veneer, for Pinus sylvestnis var. mongolica Litv. rotary cut venner, thickness is 1～2mm, and moisture content is 5.0～6.5%.
In the more excellent disclosed example of the present invention, described gluing be the glue-spread of urea-formaldehyde resin adhesive, dash board and base plate be 140～160g/m2。
In the more excellent disclosed example of the present invention, by European spruce thin plate, European spruce lath and Pinus sylvestnis var. mongolica Litv. veneer assembly gluing, adhesive used be the glue-spread of Lauxite, dash board and base plate be 140～160g/m2After assembly, digestion time is 10～15min, during hot pressing, pressure is 205～225 bar, and hot pressing temperature is 92～98 DEG C, and hot pressing time is 5min～5.5min, floor hot pressing complete after health preserving 3～5d to reduce deformation, then carrying out subdivision, the floor after subdivision first carries out sanding to base plate, then dash board carries out a coarse sand, twice washed ore, then roller coat stiffened paint.
In the more excellent disclosed example of the present invention, after described roller coat stiffened paint is for accurate sanding, first roller coat priming paint, roller coat stiffened paint after UV solidification, then solidify back roller overpainting through UV.
NullIn the more excellent disclosed example of the present invention, Described roller coat stiffened paints, its technological process is: be dried → resistant finish paint (6-8 g/m) → UV of be dried → finish paint (6-8 g/m) → UV of be dried → sanding → UV of be dried → sanding priming paint (11-14 g/m) → UV of be dried → hardening primer (14-16 g/m) → UV of be dried → sanding → hardening primer (14-16 g/m) → UV of be dried → sanding priming paint (11-14 g/m) → UV of be dried → hardening primer (16-20 g/m) → UV of be dried → anticracking priming paint (14-16 g/m) → UV of be dried → hardening primer (16-20 g/m) → UV of be dried → wear-resistant primer (14-16 g/m) → UV of be dried → sanding → aqueous priming paint (12-15 g/m) → infrared baking → anticracking priming paint (16-20 g/m) → UV of heavy putty (15-20 g/m) → UV is dried, Painting total coating weight is about 180g/m.
