Abstract

The utility model relates to a shrub composite artificial timber, wherein shrub thin sticks or straw wooden skins, wooden single plate and bamboo plates can form a surface layer, shrub (such as salix mongolica, caragana microphylla, Ammania gracilis and so on ) sticks can serve as a core layer, and the above mentioned two layers can be bonded together to form a rectangular-shaped artificial wood by using binding agent, thereby replacing the structural natural timber widely.

Description

A kind of shrub composite artificial timber

Technical field

The utility model relates to a kind of with shrub produced with combination imitation wood, belongs to wood-based plate and makes the field.

Background technology

As everyone knows; China is the country of a timber resources serious lack, and in order to alleviate imbalance between supply and demand, the wood-based plate industry is flourishing; Produce a large amount of wood-based panel products, particieboard, fiberboard, core-board and multi-plywood and timber floor etc. are arranged as common on the market.But these wood-based plates all are to be raw material with timber, and only can use as general ornament materials, can not alternative structure use with timber.So far, the domestic report that utilizes non-wooden material to make artificial square pillar timber and various artificial wood section bars of also not seeing.

The shrub resource is very abundant in China, and like caragana microphylla, salix monogolica and red building etc., these shrubs mainly have been greening, checking winds and fixing drifting sand effect, and its growth characteristics are to put down once stubble (gathering in once) in per two to three years, and have the advantages that to cut more vigorous and more vigorous., people do not have effective and reasonable the using of this precious resources for a long time.At present, though some wood-based plate producer utilizes these shrubs to make fiberboard,, because the shrub branch is thinner, when grinding fiber, do not remove branch fork and bark, and a large amount of barks is sneaked among the wood fibre, this will seriously influence the quality of product.In addition, the fibreboard product situation that is in that supply exceed demand on the domestic market, so, so far also enough large tracts of land promote the use of.Cause this inexhaustible precious resources having slatterned year after year.The generating of human salix monogolica is arranged in the recent period, we can say that this is caving-in bash.

Summary of the invention

The purpose of the utility model is exactly according to the problems referred to above; Provide a kind of and make the imitation wood with the shrub branch; Come alternative structure to use natural timber with this, both made the shrub resource obtain effective and reasonable utilization, play the effect that protects forest resources and do not cut down from the source again.

The technical scheme of the utility model is: be bonded to rectangular composite artificial timber by surface layer and sandwich layer with binder, wherein surface layer is that withe bar or the wooden skin of Sunflower Stalk, Wooden veneer or the bamboo of shrub 1mm～8mm slightd; Sandwich layer is the thick branch of shrub 8mm～30mm.

The bark of shrub branch is removed fixed-length cut-off, brushing binder on branch, the upper and lower, left and right face of in the mould blank of mating formation respectively that the withe bar orientation that scribbles binder 1mm～8mm is quantitative through dry back; Or will scribble the upper and lower surface layer that the sunflower bar of binder, wooden skin or Wooden veneer and bamboo are slightd in the mould blank of mating formation; And the directed quantitative place Min layers of the thick branch of the 8mm～30mm that will scribble binder is contained in the centre of blank in the mould, in hot press through hot-forming.

The shrub of common rich has caragana microphylla, salix monogolica and red building.Its branch thickness difference is bigger; General diameter and all is surrounded by one deck bark between 1mm～30mm, bark here is the effect of playing a separation layer; Because of it tightly is wrapped in the shrub branch; Cause binder can not direct brushing on the wooden part of branch, so need bark is removed, actual conditions are that the cleaner product quality of removing to sham wood is good more.In addition, the thickness that the shrub branch is every, length are also inequality, thus need carry out fixed-length cut-off by actual conditions, and by the thickness classification, after dry; The brushing binder; Carrying out layering mats formation; At first with (1mm～8mm) the withe bar is mated formation at the bottom of mould uniformly; After will (the thick uniform place Min layers of branch of 8mm～30mm) be contained in the intermediate layer (concentric reducer of every layer of branch need be changed 180 degree positions) of mould, at last again will (the withe bar of 1mm～8mm) is mated formation on the upper strata of mould uniformly.Put into hot press then through hot-forming.

The imitation wood who adopts technique scheme to make; Its physics, mechanical property approach the timber with density basically; The shape that is characterized in this sham wood is that the shape by mould determines; So, can once process various structures as required and use profile and wire, its product can replace log fully in the timber structure field.

Description of drawings

Accompanying drawing 1 is that the utility model fine sand withy bar is a surface layer; Than the rough sand willow is the artificial square pillar timber figure of sandwich layer.

Accompanying drawing 2 is that wooden of the utility model Sunflower Stalk is surface layer; Caragana microphylla is the artificial square pillar timber figure of sandwich layer.

Accompanying drawing 3 is that the utility model board using poplar board is a surface layer; Salix monogolica is the artificial square pillar timber figure of sandwich layer.

The specific embodiment

Below in conjunction with accompanying drawing and embodiment the present invention is further specified.

Embodiment 1:

Shown in accompanying drawing 1, the salix monogolica branch that will remove bark blocks air dry moisture content to 15% by 300mm is long; At its external coating urea-formaldehyde resin adhesive; Display to moisture content 15%, then with the withe bar (1) of 1mm～8mm uniformly orienting spreading at the bottom of mould, after with the thick branch of 8mm～30mm (2) uniformly orienting spreading in the intermediate layer of mould; Last again with the upper strata of the uniform orienting spreading of the withe bar (1) of 1mm～8mm at mould; The length of mould * wide=300mm * 50mm, subsequently with mould put into 140 the degree hot press, at 20kg/cm ²Hot pressing 50min under the pressure, the salix monogolica artificial square pillar timber of acquisition 300mm * 50mm * 50mm.

Embodiment 2:

Shown in accompanying drawing 2, will remove the Sunflower Stalk wooden (1) of exocuticle and marrow core and remove the thick bar (2) of twisting of bark, block by 300mm is long; Air dry moisture content to 20%; At its external coating urea-formaldehyde resin adhesive, display to moisture content 16%, then with the bottom of wooden (1) orienting spreading of Sunflower Stalk at mould; After with thick caragana microphylla (2) uniformly orienting spreading in the mould intermediate layer; At last again with wooden (1) orienting spreading of Sunflower Stalk on the upper strata of mould, subsequently with mould put into 150 the degree hot press, at 25kg/cm ²Hot pressing 50min under the pressure, Sunflower Stalk and the caragana microphylla composite artificial flitch of acquisition 300mm * 50mm * 50mm.
