Abstract
The invention provides a production method of straw-based artificial boards decorated by using barks, which can fully utilize crop straw resources and bark resources. The artificial boards produced by adopting the method are decorative materials which are reasonable in structure, have excellent performance, are green and environmentally-friendly and are recycled to nature. The production method of the straw-based artificial boards decorated by using the barks comprises the steps that rice/wheat straws are crushed into crushed aggregates with diameters not exceeding 10mm and are dried to a water ratio of 3 percent to 5 percent; after adhesive isocyanate of which the weight content is 5 percent to 8 percent is added to the crushed aggregates, the crushed aggregates are evenly stirred; the crushed aggregates are paved to form a slab, then the slab is hot-pressed to obtain a base material, the hot-pressing temperature is 160 to 180 DEG C, the hot-pressing pressure is 3.0 to 3.2MPa and the hot-pressing time is 0.4 to 0.6min/mm(board thickness); the bark is flattened and is bonded with the base material by using the adhesive isocyanate under the conditions that the temperature is 160 to 180 DEG C, the pressure is 0.8 to 1.5MPa and the hot-pressing time is 5min; and then sanding treatment is conducted.
Description
Technical field
The present invention relates to the production method of wood-based plate, specifically, is a kind of preparation method of artificial board of straw of bark decoration, belongs to wood-based plate and makes the field.
Background technology
At present, the development of ornament materials has the trend of two distinctnesses: the one, and environmental protection; The 2nd, recover one's original simplicity.As everyone knows, wood-based plate is the main force of ornament materials.But because a series of health problems that formaldehyde causes, people have proposed harsh requirement to the environmental-protecting performance of ornament materials.In addition, people restore the living environment in ancient times in order to pursue the living environment of ecosystem, and the visual effect of ornament materials has also been had higher requirement.
Summary of the invention
The purpose of this invention is to provide a kind of production method that can take full advantage of the artificial board of straw of decorating with bark of agricultural straw resource and bark resource, the wood-based plate of producing with the method 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 of decorating with bark, may further comprise the steps: rice/wheat straw bar particle is become to be no more than the particle of 10mm, being dried to moisture content is 3%~5%; Stir after adding the adhesive isocyanates, the weight content of adhesive is 5%~8%; Particle is mated formation into slab carry out hot pressing and obtain base material, 160~180 ℃ of hot pressing temperatures, hot pressing pressure is 3.0~3.2MPa, hot pressing time is 0.4~0.6min/mm thickness of slab; With the bark flattening-out, adopt the adhesive isocyanates, be 160~180 ℃ in temperature, pressure is 0.8~1.5MPa, under the condition of hot pressing time 5min bark and base material is glued together, and carries out sanding again and processes.
Above-mentioned production method is mated formation into particle the slab that reduces gradually to sandwich layer density from the top layer with air forming machine.Slab top layer density is large, and intensity is high, and wearability is good; Sandwich layer density is little, and elasticity is better.Air forming machine is under airflow function, the position, particle whereabouts of different sizes is different to be the larger-size sandwich layer that drops on, size is less is taken to farther place by air-flow, adopt two spreading heads just can form the stepping slab of density mechanism in pavement process, this belongs to prior art.
Beneficial effect of the present invention: the rice that the present invention decorates with bark/Wheat Straw wood-based plate has two structures layer by layer, and the top layer is natural-bark, its decoration function; The second layer is base material, is made of artificial board of straw, plays the load-bearing supporting role.It takes full advantage of agricultural straw resource and bark resource, the ornament materials that a kind of creative, environmental protection is provided, recovers one's original simplicity for masses simultaneously, and it is rational in infrastructure, and performance meets standard GB/T/T23472-2009.
Description of drawings
Fig. 1 is the artificial board of straw schematic diagram of decorating with bark.
Embodiment
The invention will be further described below in conjunction with the drawings and specific embodiments.
Embodiment 1: use the preparation of the Rice-straw Based Panel Development of birch bark decoration.
Get and give birth to then the straw straw, remove root earth, Raw material processing is become to be no more than the particle of 10mm with pulverizer;
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 applying glue equipment can be used ring type glue mixer or drum-type glue mixer;
With air forming machine particle is mated formation into the grading structure slab, the top layer is fines, and sandwich layer is coarse fodder (reducing gradually from the top layer to sandwich layer density);
Obtain base material with hot press hot pressing slab, 160~180 ℃ of hot pressing temperatures, 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), with the thickness of finger gauge control product.For preventing haftplatte, should adopt the polytetrafluoroethylene (PTFE) backing plate;
The flattening-out of bark finishing: select that defective is few, the birch bark of epidermis texture beauty; Bark is carried out flattening-out to be processed;
Birch bark and base material compound: the birch bark is sticked with glue the agent isocyanates post on the larger top layer of the density of base material, it is 160~180 ℃ in temperature, pressure is 1.0MPa, under the condition of hot pressing time 5min bark and base material is glued together, then cooling, sanding.
Embodiment 2: use the preparation of the Wheat Straw wood-based plate of oak bark decoration.
The decorative panel that makes is referring to 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 the agricultural crop straw particle, and the applying glue glue laminated forms.This decorative panel adopts double-layer structure, and the top layer is natural-bark 2, plays decoration function; The second layer is base material 2, is made of artificial board of straw, plays the load-bearing supporting role.Decorative panel with the said method preparation is carried out testing performance index according to standard GB/T/T23472-2009, all meet or exceed the requirement of standard GB/T/T23472-2009.
The present invention utilizes agricultural straw resource and bark resource, turns waste into wealth, and has improved human settlements life taste.
