Abstract
The invention relates to a bush artificial timber and a manufacturing method thereof. Bushes such as caragana korshinskii, salix mongolica, rose willow and the like are peeled, cut off at a fixed length, classified for thick and thin branches, dried, coated with a bonding agent, directionally paved in a mold in layers, and hot-pressed in a hot press to form the bush artificial timber. The invention is characterized in that thin bushes are paved on a surface layer, thick bushes are paved in the middle, and simultaneously a wooden single board, sunflower stalk wooden strips, bamboo skin, broomcorn, corn skin and other materials can also be paved on the surface to constitute a composite artificial timber. The product disclosed by the invention has a smooth surface, the density is lower, the water absorption expansion rate is small, the bush artificial timber can be widely used for replacing a structural natural timber, and a new product is provided for the artificial board industry.
Description
Technical field
The invention belongs to the manufacturing field of wood-based plate, be specifically related to a kind of shrub imitation wood and preparation method thereof.
Background technology
As everyone knows, China is the country of a timber resources serious lack, and per capita rate is well below world standard, and along with the develop rapidly of national economy and improving constantly of living standards of the people, the timber imbalance between supply and demand is growing.In recent years, because a large amount of falling trees constantly reduces area of woods, cause vicious circles such as soil erosion, ecological imbalance thus.According to relevant department's prediction, China's year wood supply deficit is up to ten thousand stere more than 4000 at present.If rely on the comprehensive utilization of direct processing of forest material and residue to be difficult to satisfy the needs of China's rapid growth timber and goods thereof separately.
In recent years, China's wood-based panel industry obtains develop rapidly, and formed with particieboard, fiberboard, core-board and multi-plywood and timber floor is master's wood-based plate industry at present.These products are in the strong timber shortage situation of having replenished of furniture manufacturing industry.But aspect structure material, do not have than quantum jump so far.Integrated timber, laminated veneer lumber is owing to all being to be raw material with the natural timber, so slowly do not form large-scale production.
The shrub resource is very abundant in China, and like caragana microphylla, salix monogolica and red building, 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 the producer that useful these shrubs are made fiberboard; Because the shrub branch is thinner, when grinding fiber, does not remove bark, and a large amount of barks is sneaked among the wood fibre; This has but seriously influenced the quality of product, so that can not 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 object of the invention is exactly according to the problems referred to above; A kind of shrub imitation wood and preparation method thereof is provided; Come alternative structure to use natural timber with this, the shrub resource that had both made obtains effective and reasonable utilization, plays the effect that protects forest resources and do not cut down from the source again.
Technical scheme of the present invention is: the imitation wood be with shrub as raw material, it is bonding to add binder, through hot press compression moulding.
Imitation wood's preparation method is: a, raw material processing, shrub by the thickness classification, is removed bark, fixed-length cut-off, drying; B, on shrub the brushing binder; C, directed quantitative mating formation in touching tool in order; D, in hot press through the hot-press solidifying moulding; E, take off palpable imitation wood.
The shrub of common rich has caragana microphylla, salix monogolica and red building.Its branch thickness difference is bigger; General diameter is between 1mm～30mm; For the expansion rate of water absorption that makes the sham wood product satisfies relative national standards, sham wood should reduce the decrement to the raw material shrub as far as possible in manufacturing process, but can reach the purpose of surfacing; So must be with shrub by thickness classification, general with diameter in thinner being divided into of 1mm～8mm (1); Diameter that will be thicker is divided into (2) at 8mm～30mm, when mating formation blank, (1) that will be thinner be laid on the top layer, and thicker (2) are laid on the intermediate layer.Can certainly connect other material at the station, surface, like wooden of Sunflower Stalk, Wooden veneer with bamboo is slightd and corn, Chinese sorghum stem such as slight at surface material.
Shrub all is surrounded by one deck bark; And also be wrapped in the very thin very thin skin of one deck in the outside of bark; The thin skin in bark and the bark outside here is the effect of playing a separation layer, because of they tightly be wrapped in shrub branch stalk, cause binder can not direct brushing on the wooden part of shrub branch stalk; So must bark be removed, actual conditions are that the cleaner quality of removing to the sham wood product is good more.
The length of every in shrub is also inequality in addition, so need carry out fixed-length cut-off by actual conditions.After dry moisture content is between 12%～250/%, brushing binder then, binder commonly used has phenolic resin glue and urea-formaldehyde resin adhesive.The again dry moisture content to 10% of shrub behind the gluing～about 25/%; After carry out place Min layers dress; (1) 1mm～8mm shrub that at first will be thinner is mated formation uniformly and is touching the bottom of tool; After will be thicker (2) 8mm～uniform place Min layers of 30mm shrub be contained in the intermediate layer of touching tool, last (1) 1mm～8mm shrub that again will be thinner is mated formation uniformly and (also can (1) be laid on the left and right sides) on the upper strata of touching tool, puts 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; And expansion rate of water absorption is little, and the shape that is characterized in this sham wood is to be determined by the shape of touching tool, so; Can once process various structures as required and use profile and wire, its product can replace natural timber fully in the timber structure field.
