Problems solved by technology

However, since the core board made of the core strip of this structure cannot limit the deformation of the veneer in the core board along the direction of the grain, this also leads to the production of the impregnated film paper facing blockboard. After using for a period of time, it is easy to cause the impregnated film paper veneered blockboard to warp along the grain direction of the board, which will affect the transverse static bending strength and surface flatness of the impregnated film paper veneered blockboard. In order to reduce the aesthetics and performance of impregnated film paper veneer blockboard

Embodiment 1

[0039] Example 1 A blockboard with impregnated adhesive film paper facing for core board application

[0040] In this embodiment, by changing the placement direction of the veneer 1 in the core board 3 of the impregnated film paper veneer blockboard, the deformation direction of the core board 3 is staggered with the wood grain direction of the veneer 1, so that the direction of the veneer 1 in the core board 3 The internal stress of the core board 3 changes, thereby improving the anti-deformation ability and surface smoothness of the impregnated film paper facing blockboard applied to the core board 3 .

[0041] Such as figure 1 As shown, this embodiment includes an upper surface layer 8 , an upper decorative layer 6 , an upper veneer layer 4 , a core board 3 , a lower veneer layer 5 , a lower decorative layer 7 and a lower surface layer 9 that are mutually bonded from top to bottom.

[0042] (1) Core board 3

[0043] Such as Figure 2 to Figure 3 As shown, the core board ...

Embodiment 2

[0055] Example 2 A method of making blockboard with impregnated adhesive film paper facing for core board application

[0056] This embodiment is used to make the impregnated film paper veneer blockboard in embodiment 1, comprises the following steps:

[0057] (1) Hot pressing of veneer 1 set of blanks to form core strip 2

[0058] Adhesively glue the veneer 1 to the veneer 1, stack N layers in order from top to bottom, and complete the assembly of the veneer 1. Wherein, N≥2, in this embodiment, N=14.

[0059] After forming the billets, the veneer layer is hot-pressed by a hot-pressing machine. The hot-pressing unit pressure is 8-12 kg / cm2, the hot-pressing time is 15-30 minutes, and the hot-pressing temperature is 115-120°C to obtain the specified size. core strip 2.

[0060] It must be ensured that the stacking direction of the N-layer veneer 1 is located in the width direction of the core strip 2, and that the direction along the grain of the veneer 1 is located in the l...

Embodiment 3

[0065] Example 3 A method of making blockboard with impregnated film paper facing for core board application

[0066] This embodiment is used to make the impregnated film paper veneer blockboard in embodiment 1, comprises the following steps:

[0067] (1) Cut wood sections into veneers 1

[0068] The wood section is cut into veneers 1 by rotary cutting or slicing, and the cutting direction is perpendicular to the direction along the grain of the veneer 1 , and the direction along the grain of the obtained veneer 1 is consistent with the length direction of the veneer 1 . The wood section is any one of poplar, camphor and Chinese fir. The obtained veneer 1 has a length of 1265 mm, a width of 650 mm, and a thickness of 3 mm. After drying, the moisture content of the veneer 1 is less than 8%.

[0069] (2) Form the board square by hot pressing the 1 group blank of the veneer

[0070] Adhesively glue the veneer 1 to the veneer 1, stack N layers in order from top to bottom, and ...

Abstract

The invention discloses a dipped film adhesive veneer core board applied by a cross-band veneer and a manufacturing method thereof. The dipped film adhesive veneer core board applied by the cross-bandveneer comprises an upper veneer layer, the cross-band veneer and a lower veneer layer bonded with each other from top to bottom; core bars for bonding the cross-band veneer are formed by hot pressing of veneers after blank assembly; and the laminating direction of the veneers is positioned in the width direction of the core bars. The manufacturing method of the dipped film adhesive veneer core board applied by the cross-band veneer comprises the following steps: the veneers are assembled as blanks for hot pressing to form the core bars; the laminating direction of the veneers is positioned in the width direction of the core bars; multiple core bars are glued to assemble as the cross-band veneer; the upper veneer layer is bonded on the upper surface of the cross-band veneer; and the lowerveneer layer is bonded on the lower surface of the cross-band veneer. The dipped film adhesive veneer core board is higher in deformation resistance, more stable in performance and longer in servicelife. The dipped film adhesive veneer core board is suitable for such fields as indoor decoration and furniture manufacturing, and particularly suitable for manufacturing of such cabinet doors as closets and cupboards.

Description

technical field [0001] The invention belongs to the technical field of boards, and relates to an impregnated adhesive film paper-decorated blockboard, in particular to an impregnated adhesive film paper-decorated blockboard for core boards and a manufacturing method thereof. Background technique [0002] As a new type of ecological board, blockboard with impregnated film paper facing not only has the beautiful appearance and similar strength of ordinary plywood, but also has lighter texture and less glue consumption than plywood. Less, more environmentally friendly. And because it can give people a sense of solid wood and meet the requirements of consumers for solid wood furniture, the impregnated film paper-faced blockboard has been widely recognized and applied as a material for interior decoration and furniture production. However, with the wide application of impregnated film paper-decorated blockboard in the fields of interior decoration, furniture production, etc., pe...
