Summary of the invention
The purpose of this invention is to provide a kind of yield rate that improves product, the processing method of the wear-resistant composite wood plate that production efficiency is high.
This practicality for the technical scheme that achieves the above object is: a kind of processing method of wear-resistant composite wood plate is characterized in that:
(1), makes slab
Rounding after softening the processing is become veneer, dried single board and its moisture content is controlled at≤7%, veneer is repaired, and the thickness of top layer veneer is greater than the thickness of its underpart veneer, to coat the veneer more than two layers of hot pressing glue with the crisscross assembly that stacks of machine direction, at normal temperatures with the pressure of 12MPa~18MPa to the slab precompressed, behind pressurize 15min~20min, put into the pressure that hot press applies 14MPa~22MPa again, temperature is controlled at 110 ℃~130 ℃, pressurize 3min~12min, naturally it is fixed thick with the abrasive band of 80~150 order numbers slab to be carried out sanding after the cooling, again the slab interlayer is stacked and be placed on ventilation, health 24h~36h under 20 ℃~25 ℃ of temperature and humidity 40%~60% condition, the moisture content of slab is controlled at≤6%, with the abrasive band of 150~200 order numbers slab is carried out sanding again;
(2), overlay compound
Balance paper, slab and wear-resisting decorative layer are placed on the lower bolster of hot press successively, upper and lower template with the pressure of 14~20MPa, temperature at 160 ℃~190 ℃ following pressurize 30s~50s, wear-resisting decorative layer, slab and balance paper hot pressing are connected into big plate, naturally cooling;
(3), health
Big plate interlayer stacked be placed on the 24h~36h that finalizes the design under ventilation, 20 ℃~25 ℃ of temperature and humidity 40%~60% condition, cutting edge, cut into required finished product.
The present invention is in the base process; control the moisture content of veneer below 7%; and the thickness of Face veneer is again greater than the thickness of its underpart veneer; when the multilayer veneer with the crisscross assembly that stacks of machine direction; and through precompressed with at HTHP; make the moisture content protection reduced levels of base material, therefore under the condition that guarantees the slab bonding strength, improve the flatness of slab.The present invention simultaneously passes through slab precompressed and hot pressing; change the density of slab; its moisture content, stress are changed; the health of slab is under specific temperature and humidity condition in addition; the moisture content protection of slab is below 6%; the internal stress of slab is reached evenly, to improve the physical stability of slab.The present invention is in the front and back of blanket health, respectively steel slab surface is carried out coarse sand and fine sand processing, the stress of slab is discharged, and make slab can reach higher flatness, owing to can reduce the distortion of big plate, therefore the wear-resistant composite wood plate surfacing that mold pressing is gone out is smooth, Clear ﹠ Transparent, has decoration functions preferably, and yield rate can be improved significantly.The present invention overlays compound temperature and pressure owing to improved balance paper, slab and wear-resisting decorative layer, has shortened conditioned time in addition, has improved production efficiency, can realize suitability for industrialized production on a large scale.
Composite wood plate of the present invention adopts mould pressing process, the convex-concave muscle of various decorative patterns can be set by cope match-plate pattern, each floral designs directly is compressed on the decorative cover of composite wood plate, because of pattern can arbitrarily be arranged according to decoration places and different the requirement, can be widely used in indoor, kitchen, the whole supporting of decoration defended in bath, can be used for floor, staircase boards, door-plate, door and window cage plate, skirting etc.
