Problems solved by technology

[0003] The structural composition and production methods of the above-mentioned finger-jointed panels have the following deficiencies: (1) When a log is made into a finger-jointed panel, due to the idea of ​​breaking first and then erecting, its utilization rate is low. It will exceed 40%; (2) In the production process, because it is broken first and then erected, each small sliver needs to be planed and removed, and then spliced, resulting in a huge waste of resources and energy in the entire production process; (3 ) When the rectangular parallelepiped strips are integrated and spliced ​​into finger-jointed panels, a large amount of adhesive is required for horizontal and finger-jointed joints, which will cause environmental pollution, which is contrary to the concept of environmental protection and safety advocated by wooden materials; (4) Finger-joined panels cannot Change according to needs to obtain special properties for specific applications in corresponding occasions. Further processing and manufacturing are required, which increases the intermediate links before application and reduces the application range of wood materials.
(5) It is easy to crack in different regions and different environments

Embodiment 1

[0059] This embodiment is a commonly used solid wood sawn timber in the wood processing industry. It is processed by longitudinal sawing of logs to make boards and squares with a certain cross-sectional size or cross-sectional size. Planks or squares are the most common and widely used It is also a raw material for processing other wood products. The plank in this embodiment refers to plank or sawn longitudinally along the heart of the tree and along the growth direction of the wood as the basis of the composite material, as a solid wood material directly processed from the log, and has been dried.

[0060] The specific structure is composed of figure 1 As shown, the cross section of the plate is rectangular, the two sides with longer sides are used as the upper surface and the lower surface of the plate, and the two sides with shorter sides are used as the left and right sides. For the artificial depression that destroys the growth stress processed by woodworking saws, that ...

Embodiment 2

[0064] The base material of this embodiment 2 is the same as that of embodiment 1, and the purpose of destroying the growth stress of the wood itself is achieved by processing artificial depressions on the board.

[0065] Such as Figure 6 As shown, the difference between this embodiment and Embodiment 1 is that in order to achieve the same purpose of eliminating the growth stress of trees, several holes can also be processed on the plate, and these holes can be unpenetrated on one side, or can be It is not pierced on both sides, or it can be a hole that penetrates both sides. The shape of the hole can be circular, elliptical, and other shapes such as rhombus and polygon. A common hole is a deep hole perpendicular to the side of the solid wood sawn timber, and the deep hole does not penetrate the solid wood sawn timber laterally; the described hole may be a through hole perpendicular to the side of the solid wood sawn timber, and the through hole runs through the solid wood s...

Embodiment 3

[0069] Embodiment 3 is a further improvement on the basis of Embodiment 1 and Embodiment 2. Specifically, the time-delayed setting material or the quick-setting material is filled and coated on the wooden board processed with wire grooves. That is, by filling the linear grooves with materials such as calcium carbonate and adhesives, the gaps are cured to form a more stable shape, reducing deformation and increasing overall stability.

[0070] The time-delayed solidification material in the embodiment can be cement, also can calcium carbonate add adhesive, or diatom ooze, polyurethane foaming agent, glass cement etc., their common feature is that flow state is first, waits to be filled and painted slowly Slow solidification, so as to enhance the strength of the base material, as a new type of wood-based composite material.

[0071] In production practice, the base material can be soft wood such as pine, poplar, fir, etc., and after the growth stress is destroyed by slotting, the ...

Abstract

The invention relates to a novel wood-based composite material, and belongs to the field of composite materials. The novel wood-based composite material takes solid wood sawn timber as the base, artificial concavities used for damaging tree growth stress are machined in the solid wood sawn timber, and the solid wood sawn timber with the artificial concavities serves as the base material of the wood-based composite material. Attachments are arranged on the base material, and the attachments with different properties and the base material are combined to form the wood-based composite material. According to the composite material, the structural form and manufacturing process of existing wood are changed, part of the properties of the wood are changed or strengthened, a novel concept and process are provided for efficient use of wood plates, and the novel wood-based composite material is revolutionary enough in the field of wood plates.

Description

technical field [0001] The invention relates to the field of materials, in particular to a composite material, which refers to a wood-based composite material with special properties composed of solid wood materials and other materials. Background technique [0002] Wood is a large branch in the field of materials and is widely used in various industrial and agricultural sectors. In most occasions, the application of wood exists in the form of planks and square logs, collectively referred to as solid wood sawn timber, which is made of logs through longitudinal sawing and has a certain cross-sectional size or cross-sectional size. Consists of four side surfaces. At present, the wood-based panels produced with solid wood and adhesives as raw materials in industrial production mainly refer to spliced ​​panels, MDF, oriented strand boards, blockboards and plywood. Among them, the finger-jointed board is made of many small wooden strips spliced ​​into a unified specification fo...
