Embodiment 1

[0016] The moso bamboo is cut off, cut open, knotted, yellowed and greened, cut into strips, and processed into long and short bamboo strips with a width of 20mm and a thickness of 3mm. The length of the long bamboo strips depends on the specifications of the board. The length of the short bamboo strips is 15-30cm, and the bamboo strips of equal thickness are machine-woven with cotton and linen threads into such figure 2 The core material of the long-short strip unit member realizes the "integralization" of the core material and is used to make the core material of the hollow thick curtain bamboo plywood.

Embodiment 2

[0018] The wooden material is processed into L-shaped wooden strips and Z-shaped wooden strips. The length is determined according to the specifications of the board. The width of the wide part and the narrow part are 60mm and 30mm respectively, and the thickness is 10mm. braided like Figure 4 The L-Z type core material realizes the "integralization" of the core material, and is used to make the core material of the hollow thin wood board.

Embodiment 3

[0020] Thin MDF or thin particleboard is processed into a long strip unit member with a height of 80mm (the length is determined according to the specification of the hollow board), and the wooden material is processed into a short strip unit member with a height of 150mm×60mm×80mm. The strip unit members are glued together to form figure 2 The core material of long-short strip unit members is used to make the core material of thicker hollow panels (such as room partitions).

Abstract

The invention relates to a making method for hollow slab sandwich layer material, which is formed by combining a plurality of wood-bamboo strip elements with various shapes. The wood-bamboo strip element is processed with wood-bamboo material or artificial panel; the shape comprises seven kinds which are long strip, short strip, left bracket shape, Z shape, L shape, I shape and T shape. Two or more than two wood-bamboo elements with various shapes and equal thickness are made to the sandwich layer material with hollow structure by using liner connection or adhesive connection. The hollow making method for slab sandwich layer material has the advantages of mechanized operating, simple technology, high efficiency, less material consumption, light weight, low cost and wide applicable range.

Description

technical field [0001] The invention belongs to the technical field of wood-based panel manufacturing, and in particular relates to a novel manufacturing method for a core layer material of a hollow panel. Background technique [0002] Most of the hollow panels are composed of surface materials and hollow structure core materials placed between the two surface materials, which have the characteristics of low density, good sound insulation and heat insulation performance. In the existing hollow panels, some core materials only have a frame, few support points between the upper and lower panels, and have poor mechanical properties such as strength and stiffness, such as hollow plywood doors; some core materials use a combination of network structure and frame material , such as CN03248735.5 a kind of hollow bamboo plywood, complex structure, high precision requirements, not easy to mechanized operation, laborious, low efficiency, high production cost.
