Abstract
The invention provides a production method of a wheat straw artificial board decorated by oak barks. Wheat straw resources and oak bark resources can be sufficiently used, and the artificial board produced by the method is a decorative material which is reasonable in structure, superior in performance, green, environmentally friendly and natural. The production method is characterized in that wheat straws are crushed into crushed materials not exceeding 10mm and dried until the water content is 3%-5%, the crushed materials are uniformly stirred after adhesive isocyanate is added, the weight content of adhesives is 5%-8%, the crushed materials are laid into slabs and hot-pressed to obtain base materials, hot-pressing temperature is 160-180 DEG C, hot-pressing pressure is 3.0-3.2MPa, hot-pressing time is 0.4-0.6min/mm of the thickness of the board, the barks are flattened, and the barks and the base materials are adhered together and then sanded under the condition of the temperature of 160-180 DEG C, the pressure of 1.3MPa and the hot-pressing time of 5min.
Description
Technical field
The divisional application that the application is the applying date is on December 12nd, 2012, application number is 2012105325068, denomination of invention is the original application of the production method of the artificial board of straw of a kind of bark decoration.
The present invention relates to the production method of wood-based plate, specifically, be the preparation method of the artificial board of straw of a kind of bark decoration, belong to wood-based plate and manufacture field.
Background technology
At present, the development of ornament materials has two distinct trend: one is environmental protection; Two is recover one's original simplicity.As everyone knows, wood-based plate is the main force of ornament materials.But due to a series of health problems that formaldehyde causes, the environmental-protecting performance of people to ornament materials proposes harsh requirement.In addition, people, in order to pursue the living environment of ecosystem, restore living environment in ancient times, there has also been higher requirement to the visual effect of ornament materials.
Summary of the invention
The object of this invention is to provide a kind of production method that can make full use of the artificial board of straw with bark decoration of agricultural straw resource and bark resource, the wood-based plate produced in this way is a kind of rational in infrastructure, superior performance, environmental protection, the ornament materials of recovering one's original simplicity.
The production method of the above-mentioned artificial board of straw with bark decoration, comprise the following steps: particle rice/wheat straw bar particle being become to be no more than 10mm, being dried to moisture content is 3% ~ 5%; Stir after adding adhesive isocyanates, the weight content of adhesive is 5% ~ 8%; Particle is mated formation into slab to carry out hot pressing and obtain base material, hot pressing temperature 160 ~ 180 DEG C, hot pressing pressure is 3.0 ~ 3.2MPa, and hot pressing time is 0.4 ~ 0.6min/mm thickness of slab; By bark flattening-out, adopt adhesive isocyanates, be 160 ~ 180 DEG C in temperature, pressure is 0.8 ~ 1.5MPa, bark and base material is glued together under the condition of hot pressing time 5min, then carries out sanding process.
Above-mentioned production method, mats formation into the slab reduced gradually from top layer to core concentration by particle with air forming machine.Slab top layer density is large, and intensity is high, and wearability is good; Core concentration is little, and elasticity is better.Air forming machine is under airflow function, the particle drop-off positions of different size is different namely larger-sizely drops on sandwich layer, what size was less is taken to farther place by air-flow, in pavement process, adopt two spreading heads just can form the stepping slab mechanism of density, this belongs to prior art.
Beneficial effect of the present invention: the rice/Wheat Straw wood-based plate of the present invention's bark decoration has two-layer Rotating fields, and top layer is natural-bark, its decoration function; The second layer is base material, is made up of artificial board of straw, plays load bearing support effect.It takes full advantage of agricultural straw resource and bark resource, and be the ornament materials that masses provide a kind of creative, environmental protection, recover one's original simplicity, it is rational in infrastructure, and performance meets standard GB/T/T23472-2009 simultaneously.
Accompanying drawing explanation
Fig. 1 is the artificial board of straw schematic diagram with bark decoration.
Embodiment
Below in conjunction with the drawings and specific embodiments, the invention will be further described.
Embodiment 1: with the preparation of the Rice-straw Based Panel Development of birch bark decoration.
get raw straw straw then, remove root earth, become to be no more than the particle of 10mm with pulverizer by Raw material processing;
with rotor-type drier or channel-type drying machine, particle being dried to moisture content is 3% ~ 5%;
take isocyanates as adhesive, glue consumption is 5% ~ 8%, and sizing equipment can use ring type glue mixer or drum-type glue mixer;
with air forming machine, particle is mated formation into grading structure slab, top layer is fines, and sandwich layer is coarse fodder (reducing gradually from top layer to core concentration);
base material is obtained with hot press hot pressing slab, hot pressing temperature 160 ~ 180 DEG C, unit pressure is 3.0 ~ 3.2MPa, and hot pressing time is 0.4 ~ 0.6min/mm thickness of slab (namely calculating hot pressing time according to the thickness H mm of slab is 0.4 ~ 0.6H min), controls the thickness of product by finger gauge.For preventing haftplatte, polytetrafluoroethylene (PTFE) backing plate should be adopted;
cooling, cutting edge, sanding;
the flattening-out finishing of bark: select the birch bark that defect is few, skin pattern is beautiful; Flattening-out process is carried out to bark;
the compound of birch bark and base material: birch bark is sticked with glue agent isocyanates and post on the top layer that the density of base material is larger, it is 160 ~ 180 DEG C in temperature, pressure is 1.0MPa, bark and base material is glued together under the condition of hot pressing time 5min, then cooling, sanding.
Embodiment 2: with the preparation of the Wheat Straw wood-based plate of oak bark decoration.
Embodiment 2 is from the different of embodiment 1: instead of the rice straw in embodiment 1 with wheat straw bar, instead of the birch bark in embodiment 1 with oak bark; The compound tense hot pressing pressure of oak bark and base material is 1.3MPa.
Obtained decorative panel is see Fig. 1, and it comprises artificial straw plate substrate 1 and is attached to the bark 2 of base material upper surface as the note on top layer.Base material 1 is by agricultural crop straw particle, and applying glue glue laminated composition.This decorative panel adopts double-layer structure, and top layer is natural-bark 2, plays decoration function; The second layer is base material 2, is made up of artificial board of straw, plays load bearing support effect.According to standard GB/T/T23472-2009, testing performance index is carried out to the decorative panel prepared with said method, all meets or exceeds the requirement of standard GB/T/T23472-2009.
The present invention utilizes agricultural straw resource and bark resource, turns waste into wealth, and improves human settlements life taste.
