Abstract

The utility model discloses a novel double-layer core solid wood composite board, which comprises a core board I and a core board II which are formed by bonding and hot pressing, wherein the top surface of the core board I and the bottom surface of the core board II are respectively bonded and hot pressed with at least one layer of poplar core board or density board; the core plates I and II are respectively formed by longitudinally and transversely splicing a plurality of laths, two side edges of the laths are connected in an adhesive mode, and two ends of the laths are spliced end to end. Each layer of core plate is formed by splicing a plurality of strips vertically and horizontally, and compared with the traditional single-layer sawed core plate, the structure is more stable and is not easy to deform. The traditional plate core is sawed, more wood chips can be generated, the outturn percentage is about 65%, the outturn percentage of the plate core formed by rotary cutting at present is about 95%, the outturn percentage is high, and raw materials are not wasted.

Description

Novel double-layer core solid wood composite board

Technical Field

The utility model belongs to the technical field of solid wood composite boards, and particularly relates to a novel double-layer core solid wood composite board.

Background

In the prior art, the laminated structure of the composite board is mostly formed by mutually bonding and hot-pressing a plurality of laminated boards. If the thickness of the common single-layer core board is 9-20mm, the composite board is formed after a plurality of layers of board skins are respectively bonded on the top surface and the bottom surface of the core board.

The core board of the composite board has a single-layer solid wood structure, so the core board has high manufacturing cost, is easy to deform after being used for a period of time, has poor stability, and greatly influences the quality and the service life of the product. Moreover, the single-layer core plate needs to be sawed due to the thick thickness, and the sawing mode causes low outturn rate and generates about 30-40% of wood chips, so the manufacturing cost is high and the raw materials are wasted to a certain extent.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problems in the prior art and provide a novel double-layer core solid wood composite board to overcome the defects in the prior art.

In order to achieve the purpose, the novel double-layer core solid wood composite board comprises a core board I and a core board II which are mutually bonded and hot-pressed up and down through an adhesive, wherein the top surface of the core board I and the bottom surface of the core board II are respectively bonded and hot-pressed by the adhesive to form at least one layer of poplar core board or density board;

the core plate I and the core plate II are formed by splicing a plurality of battens with the same thickness vertically and horizontally, two side edges of the battens are mutually bonded and connected through the adhesive, and two ends of the battens are mutually spliced end to end.

The thickness of the core plate I and the thickness of the core plate II are both 4.5-10 mm.

The thickness of the lath is 4.5-10mm, the width is 60mm, and the length is 500-1000 mm.

The thickness of the poplar core board or the density board is 1.7-3 mm.

The adhesive is environmentally friendly and meets the latest national E0 standard.

The utility model has reasonable structure, the core board is formed by bonding two layers of structures, and each layer of core board is formed by vertically and horizontally splicing a plurality of laths. The traditional plate core is sawed, more wood chips can be generated, the outturn percentage is about 65%, the outturn percentage of the plate core formed by rotary cutting at present is about 95%, the outturn percentage is high, and raw materials are not wasted.
