Abstract

The invention discloses a manufacturing method of high-fidelity recombination solid-wood materials. The manufacturing method includes steps of rotationally cutting or slicing small-diameter materials into a veneer and drying and treating for standby application; gluing, impregnating or spraying glue on the dried veneer for standby application; placing different types and color shades of glued veneers into molds for prepressing during alternative assembly according to natural timber growth rings after stereoscopically rift-grain assembly or rolling; dyeing a part of veneers firstly and placing different color shades of glue veneers into molds for prepressing after rift-grain alternative assembly or rolling; subjecting pre-pressed blank to high-frequency hot press or four-side extrusion to obtain high-fidelity artificial solid-wood materials; sawing the solid-wood into square materials according to the solid-wood sawn timber manner. The manufactured recombination solid-wood materials have the advantages of vivid texture, texture and machining and using of natural timber, are stable in size and high in additional value and can be fungible for large-diameter solid wood.

Description

A kind of manufacture method of high-fidelity restructuring solid wood material

Technical field

The present invention relates to a kind of manufacture method of artificial solid wood, particularly relate to a kind of method utilizing undersized log to manufacture high-fidelity restructuring solid wood.

Background technology

High-grade solid wood board is from natural large footpath level log.Along with the exhaustion of China's timber resources and the protection of wildwood, domestic large footpath log is fewer and feweri, and the demand being difficult to meet socio-economic development transfers a large amount of import.The external dependence degree of current China timber, more than 50%, constitutes serious threat to the timber strategy of country.Long term growth China also should be conceived to utilize path fast growing wood make full use of reach self-sufficiency.And path fast growing wood is difficult to meet instructions for use because of born defects such as footpath level are little, material is poor, volume recovery is low, utilization rate is low.Along with growth in the living standard and improvement, people more and more favor the decorative pattern of the natural texture of solid wood products, natural characteristic, visual effect and beauty.Be nothing but solid wood sawing integrated technique (as integrated timber etc.) and particle glue and technique (as particieboard etc.) for the Land use systems that timber with small diameter is traditional, the former utilization rate is low, cost is high, and the latter has lost the true colours of solid wood.

Disclose a kind of manufacture method of solid wood board of recombinating in CN103817750A, the Scrimber that the method obtains is that a kind of colored single palte is recombinated the restructuring timber of parallel superposition, and resulting materials is all quarter sawing material (being all parallel wood grain).

Summary of the invention

A kind of outward appearance, material, functional characteristic and solid wood height is the object of the present invention is to provide to be similar to and the high-fidelity being better than solid wood is recombinated the manufacture method of solid wood material, this restructuring solid wood material is produced with undersized log and slicing rotary-cut particle, and stock utilization is high close to 100%; Restructuring solid wood material adopts CAD, by natural annual rings of timber constituted mode, through 3 D stereo rift grain assembly, precompressed, hot pressing and obtaining, product had both had natural timber texture true to nature, texture and processing operating characteristic, dimensionally stable again, the high-fidelity restructuring solid wood material of arbitrary dimension can be processed into by instructions for use, added value of product is high, be widely used, alternative entity large footpath level timber uses.

For achieving the above object, the present invention takes following technical scheme:

A manufacture method for high-fidelity restructuring solid wood material, as shown in Figure 1, comprises following concrete steps:

A, small dimension wood are processed into veneer or the veneer of 0.3 ~ 3mm through rotary-cut or slicing, more stand-by after drying process;

B, dry veneer or veneer are stand-by after gluing, impregnation or glue spraying, resin application methods: two-sided applying glue; Two-sided resin added: 160 ~ 200g/m 2;

C, when the alternate assembly of the applying glue veneer using different tree species, shade to differ, by the natural annual rings of timber form of the composition, after 3 D stereo rift grain assembly or volume base, put into mould precompressed; During with same seeds light color veneer assembly, can first by part single-plate dyeing, then put into mould precompressed after the alternate assembly of applying glue veneer rift grain differed by shade or volume base;

D, precompressed slab obtain the artificial solid wood square bar of high-fidelity through High frequency heating or four sides extruding, and concrete moulding process is as follows: mode of exerting pressure: four sides extruding; Hot pressing mode: High frequency heating; Pressing time: 8 ~ 15min; Moulding pressure: 1 ~ 3MPa;

E, by the processing mode of log sawn timber, the sawing of above-mentioned solid wood square bar is become the plate square bar of designing requirement, namely obtain high-fidelity of the present invention restructuring solid wood material.

Tool of the present invention has the following advantages:

1, described 3 D stereo rift grain assembly or volume base, mould precompressed is hot-forming, CAD can be adopted to carry out three-dimensional matching board, obtained artificial solid wood square bar, sawing processing postmenstruation obtains high-fidelity of the present invention restructuring solid wood material again, thus realizes the high fidelity effect of artificial solid wood.

2, the high-fidelity restructuring solid wood material of manufacture of the present invention not only has the natural texture of natural timber, visual characteristic, warm texture and machining attribute, simultaneously owing to adopting rotary-cut or sliced veneer processing, the utilization rate of timber with small diameter is made to reach more than 90%, process can reject larger defect, thus excellent, can be processed into by designing requirement the restructuring solid wood material that any specification is even processed into the particular/special requirement such as hollow, different in nature; CAD particularly can be adopted to realize 3 D stereo emulation rift grain matching board, thus the solid wood of natural wood extremely to the greatest extent can be obtained, then process the restructuring solid wood obtaining and there is natural wood texture vivid effect and using function through traditional sawing mode; By different tree species any combination thereof, adopt CAD can also obtain the unexistent special texture of natural timber, to meet the individual demand of people; Product easily realizes dyeing, anticorrosion, insect protected, fire prevention process, easily realize the batch production of process, intensive, specialized, thus change the transformation of the traditional processing mode of woodwork, drive woodwork processing industry production model, promote the strategical reajustment of the industrial structure.

3, compared to CN103817750A, the annual ring direction loop configurations of spontaneous growth timber pressed by veneer by the present invention, through mold pressing first obtained artificial log square bar, obtain through Cutting indexes again, sheets thus obtained existing quarter sawing material (parallel wood grain) also has profoundly cuts material (chevron wood grain), and the veneer of machine Computer Aided Design and dyeing process as calculated also can obtain the special wood grain that natural timber does not have; The wood grain of recombined material has the effect of high fidelity, and has all visual characteristics of solid wood and processing, operating characteristic.

Accompanying drawing explanation

Fig. 1 is the manufacturing process flow diagram of high-fidelity of the present invention restructuring solid wood material.
