Description
Technical field
The invention belongs to wood base composite material technical field, and in particular to a kind of high-weatherability energy wood combination material.
Background technology
Current China economy is fast-developing, but but reduction causes timber supply and demand breach increasingly to log yield year by year
Greatly.Therefore, a kind of new product is found to alleviate imbalance between supply and demand as the task of top priority.The fast growing wood aboundresources of China, accumulation
Greatly, substantial amounts of fast-growing richness production woods resource still needs rationally efficiently to be developed at present.Scrimber is with low-quality fast-growing path
Material and thinnings are raw material, through grind rub with the hands processing separation be open into constantly split, the curtain sheet shape wood beam that longitudinal direction is loose and staggeredly connected,
By dry
It is dry, be glued, mat formation, the process such as hot pressing reconfigures the novel artificial solid wood processed.To this material of Scrimber
The utilization of material can be cost-effective, can effectively protect forest resources again, moreover it is possible to alleviate imbalance between supply and demand, to the meaning of sustainable development
Justice is great.
The intensity and performance and timber of Scrimber are closest, and its birth has far-reaching influence to industry of artificial boards.
Its feature is that the construction material of function admirable thinnings, the small dimension wood of artificial fast-growing can be reassembled into.The longitudinal direction of recombinant material is fine
Dimension makes it still have the intensity along machine direction, and defects in timber have been excluded due to the effect of restructuring, therefore improve material
Quality, improves raw material availability.
The thought of Scrimber is to be proposed by Australian researchers JDColeman in 1973 first, and he is in analysis
Curtain sheet formula wood Shu Jiagong imagination has been sprouted during other materials, i.e., do not upset the orientation of fiber, retain timber fundamental characteristics
And then it is reassembled into new product.Australian forest-science institute is recognized Coleman imagination, and starts to study emphatically.
They have applied for Scrimber patent first, then the production technology of Scrimber and equipment have been carried out comprehensive detailed research and into
Work(develops the manufacturing equipment of Scrimber, and the equipment was put into operation in 1986.But main asking of running into process of production
Topic is:1. material moisture content when processing is dried is difficult to control within zone of reasonableness, because the material of actual production contains
Water rate is widely different to cause Scrimber Density Distribution when carrying out hot pressing uneven；2. because Scrimber is vertical after raw material is rolled
Mated formation upwards, this flooring mode can produce such a problem, although the longitudinal strength of i.e. recombinant material has compared with raw material
Certain lifting, but transverse strength declines substantially, so that product easily has cupped phenomenon；3. Scrimber
The glueing material of use is Tannin adhesive, and the product perception shade deviation and rough surface of production, reprocessing can improve cost again.
Various countries researcher has drawn experiences and lessons from actual production, and Scrimber research does not stop but positive
More researchs are put into, scholars have carried out exploratory development to many fast growing woods manufacture Scrimber feasibility, for restructuring carpenter
The production of industry metaplasia provides more wide space.Especially it is worth mentioning that Japanese wood science be able to can grow up, male dry chapter etc. utilizes wooden beam
Specific form have developed Scrimber laminated particle-board.The particieboard efficiently solves the cupping problem of Scrimber.
The wood materials generally used under construction at present, are mainly used in interior, and Yin Qiruo is applied to outdoor and generally deposited
In following shortcoming：1st, long-term to be faded through sunlight irradiation is easy, weatherability is poor；2nd, service life is short, it is necessary to which annual brush outside plank
One layer of preservative oil, maintenance cost is high.
The content of the invention
In view of this, the present invention provides a kind of high-weatherability energy wood combination material, and it has simple in construction, weatherability
Well, the characteristics of good antiseptic property, temperature-adjustable.
The technical scheme is that：A kind of high-weatherability energy wood combination material, including jacket layer and sandwich layer, the jacket layer
Be to be spliced by sub-assembly, be provided with sandwich layer inside the jacket layer, the sandwich layer be the first core plate by being staggered successively and
Second core plate is constituted, and first core plate is poplar core plate, and second core plate is camphorwood core plate, and the jacket layer passes through with sandwich layer
Adhesive combination connection.Particularly, first core plate, the second core plate can be by the way that any prior art is to wood raw material or adds
The processing of work leftover bits and pieces is prepared.
Further, the outer cover of first core plate is provided with warp knit cushion, and the warp knit cushion internal symmetry is set
There is buffer unit.
Further, the outer cover of second core plate is provided with weft-knitted cushion, and the weft-knitted buffer-layer surface is provided with painting
Layer.
Particularly, the warp knit cushion uses water soluble vinylon filament fibrous layer.The warp knit cushion can be by appointing
One existing warp knitting is realized.
Further, the averag density of first core plate is 0.3g/cm3 ＜ ρ ＜ 0.5g/cm3.
Further, the averag density of second core plate is 0.5g/cm3≤ρ ＜ 0.6g/cm3.
The present invention can effectively control the weight of material, while ensureing this hair by the combination of high-density plate and low-density plank
Bright intensity, improves the combination property of the present invention.
Further, the buffer unit is made up of the buffer cell set gradually, and the buffer cell is by symmetrical
The first buffer part set and the second buffer part composition.The buffer unit of the present invention can be realized by the first buffer part between core plate
The buffering of longitudinal force, realizes the buffering from horizontal active force, it is ensured that stabilization of the invention by the second buffer unit
Property.The buffer unit that the present invention is used prepares for any material with pooling feature in the prior art.
Further, the structure of the weft-knitted cushion is superhigh molecular weight polyethylene fibers cushion, super high molecular weight

The triangle arrangement of squama fabric is as shown in fig. 7, mono- complete organization of 16F.The characteristics of such product is that preceding 12F braidings improve imitative fish
Squama fabric, behind 4F braiding latitude plain stitch, formed travers cushion.By the setting of weft-knitted cushion, it can be achieved
Cushioning breathable, but the function of not moisture-inhibiting, can adjust the temperature of indoor environment.
In the present invention, the superhigh molecular weight polyethylene fibers (abbreviation UHMWPE) of use, also known as high-strength and high-modulus polyethylene fiber
Dimension, is current specific strength and specific modulus highest fiber in the world, and its molecular weight is spun in 1,000,000-500 ten thousand polyethylene institute
Fiber.With high specific strength, high ratio modulus；Fibre density is low；Extension at break is low, work to break is big, with very strong absorption energy
Ability, thus with prominent impact resistance and anti-cut；Resistant to chemical etching, wearability, there is longer flex life etc.
Advantage.
Mechanics Performance Testing is carried out to the weft-knitted cushion of the present invention, surface, the ess-strain in cross directional stretch is studied
Approximately linear is presented in curve, and oblique and longitudinal stretching curve is in the starting stage close to linear, and as strain increases, curve is in non-thread
Property, longitudinal stretching has obvious yield phenomenon.Along the tensile break strength and modulus highest in row direction, oblique to take second place, edge
Stringer direction is minimum；Elongation strain is minimum along row direction, oblique placed in the middle, maximum along stringer direction；Tensile property anisotropy
