Embodiment Construction

[0024] The core layer 2 of the flat surface wood oriented strand board is OSB, which will be processed along the direction of the wood grain with a length of 30mm-150mm, a width of 5mm-30mm, and a thickness of 0.3mm-1.2mm. After five layers are installed, it is then heat-pressed and formed. The surface layer 1 and the bottom layer 3, that is, the first layer and the last layer, are made of wood after slicing, softening, grinding and fiber separation, after drying, screening, and phenolic resin as the adhesive for sizing and paving, and the core layer 2 combined, then pre-pressed and hot-pressed, and finally finished with plain surface treatment to form a three-layer structure, the core layer 2 is OSB, the surface layer 1 and the bottom layer 3 are wood fine material layers with a smooth surface wood oriented strand board.

Abstract

The invention provides a smooth surface wood oriented structure flakeboard and a preparation method used for the flakeboard, belonging to the technical field of artificial board, and more particularly relates to a modified wood oriented structure flakeboard and a preparation method of the flakeboard. The smooth surface wood oriented structure flakeboard of the invention is formed by the bonding of a surface layer, a core layer and a bottom layer; the core layer structure is the wood oriented structure flakeboard (OSB); the flakeboard is characterized in that the surface layer and the bottom layer are wood fine layers. The preparation method of the invention comprises the steps as follows: a wood slicing, grinding and fibre separation device is added at the front section of the preparation production line so as to manufacture and produce certain wood fine materials; the fine materials are dried, screened and chosen to carry out the sizing operation; subsequently, a paving machine is respectively arranged at the front section and the final section of the paving production line; a fine material layer is added at the surface layer and the bottom layer before the OSB is formed; subsequently, the hot extruding and plain plate disposals are carried out so as to prepare the flakeboard with smooth and flat surface.

Description

technical field [0001] The invention belongs to the technical field of man-made boards, and in particular relates to an improved wood oriented particle board, its manufacturing method and application. Background technique [0002] The traditional wood-based oriented strand board (OSB for short) is made of small-diameter wood, thinning wood, wood core, board skin, branch wood and other wood as raw materials, and is processed into slices along the direction of wood grain by special planing equipment. Drying, sizing, and special paving equipment are used to pave the core layer slices in a criss-cross pattern, and then heat-pressed to form a wood-based panel. [0003] Because OSB adopts special technology and special equipment, it basically retains the natural characteristics of wood, so it has the advantages of high bending strength, small linear expansion coefficient, good dimensional stability, uniform material, strong nail holding force, and easy surface decoration, etc. . ...
