Abstract
The utility model relates to a laminated wood board with a plurality of expansion joints. A single layer board is bonded on each side of a board core, a face plate is bonded outside each single layer board, and a plurality of expansion joints are formed on the two surfaces of the board core. The laminated wood board solves the technical problem of deformation. During the hot pressing process of the laminated wood board, the water vapor formed in the wood board can be rapidly discharged from the expansion joints, so as to basically eliminate the bubbling and peeling phenomena. The free formaldehyde in urine-formaldehyde resin is also released in a large amount together with the water vapor, resulting in about 70% reduction in the free formaldehyde compared with the content of the free formaldehyde in the wood board under the conventional production process conditions, so as to meet the requirements for environmental friendliness and further reduce the harm of formaldehyde on human body. Moreover, the laminated wood board reduces hot pressing time, so as to improve production efficiency and reduce production cost.
Description
Technical field:
The utility model relates to a kind of core-board, and especially a kind of expansion joint core-board is the decorations wood-based plates.
Background technology:
Core-board has become one of main force's kind of China's wood-based plate at present as the main sheet material in the house decoration, but many defectives such as that most core-board exists is easily deformable, bubbling and free formaldehyde release height.The one, core-board is after depositing or using a period of time, because the influence that sheet material is changed by ambient temperature, humidity, and make sheet material or goods torsional deformation, thus the use of sheet material and the outward appearance of goods influenced; The 2nd, core-board is in the process of hot pressing, owing to be subjected to the influence of HTHP, moisture residual in the plate core becomes steam rapidly under the influence of high temperature, and steam can not be discharged rapidly under the effect of high pressure, so cause core-board bubbling, peeling.
Summary of the invention:
The purpose of this utility model provides a kind of expansion joint core-board, solves that core-board is easily deformable, bubbling and the high defective of free formaldehyde release.
The purpose of this utility model realizes as follows: this expansion joint core-board, and one deck veneer of fitting respectively in plate core both sides, the perhaps outside of the veneer deck panels of fitting again, plate core two plate faces have the several expansion seam.
Position, the expansion joint interlaced arrangement of the expansion joint of plate core upper face and plate core lower face.
The beneficial effects of the utility model are: the technical barrier that has solved the core-board distortion; Core-board is in the process of hot pressing, the steam that forms in the sheet material can be discharged rapidly along the expansion joint, bubbling, skin effect phenomenon have thoroughly been solved, free formaldehyde in the pollopas is also together discharged in a large number with steam simultaneously, can reduce about 70% than the free formaldehyde in the sheet material under the traditional processing technology condition, thereby reach environmental protection requirement, further reduced the harm of formaldehyde human body.In addition, can also reduce the hot pressing time of core-board, enhance productivity, reduce production costs.
Description of drawings:
Accompanying drawing is the structural representation of the utility model expansion joint core-board.
The specific embodiment:
With reference to accompanying drawing, this expansion joint core-board, one deck veneer 2 of fitting respectively in plate core 1 both sides, the outside of veneer 2 deck panels 3 of fitting again, 1 liang of plate face of plate core has several expansion seam 4, the expansion joint 4 of plate core 1 upper face and the expansion joint 4 position interlaced arrangement of plate core 1 lower face.
Claims (2)
1, a kind of expansion joint core-board, one deck veneer of fitting respectively in plate core both sides, the deck panels of perhaps fitting again in the outside of veneer is characterized in that: plate core (1) two plate face has several expansion seam (4).
2, expansion joint according to claim 1 core-board is characterized in that: position, expansion joint (4) interlaced arrangement of the expansion joint (4) of plate core (1) upper face and plate core (1) lower face.
