Problems solved by technology
Moreover, due to deforestation and unplanned afforestation, not only the resources are reduced, but also an important cause of the deterioration of the global environment.
On the other hand, with the improvement of living standards, a large amount of waste wood is produced, but if it is not used effectively and only stays on incineration, it will cause a waste of resources
Moreover, although the reuse of thinned timber is advocated, its use range is narrow, and its use, quality, and quantity are also limited.

Embodiment Construction
[0016] Next, preferred embodiments of the present invention will be described with reference to the drawings. figure 1 It is a process drawing which shows the 1st example of the manufacturing method of this invention. First, as the first step A, materials are prepared. This process is necessary when producing regenerated wood, but there is no problem as long as it is natural wood, such as waste wood and thinned wood, which are selected as materials. However, plywood using chemicals as adhesives was excluded from the material due to possible undesirable chemical reactions during the manufacturing process. Also, it is also included in the present invention that the used plywood laminated wood is recycled when it is not needed. Next, as the second step B, the collected materials are sorted and sorted. In this process, select and distinguish according to the type of wood, such as shirt material, cypress material, etc. It is also possible to mix the woods according to usage and...

Waste wood is recycled into a large cross-section wood board without using a hazardous material as a binder. The invention provides a method for manufacturing a recycled wood product, and includes the steps of atomizing, to a wood material containing small wood chips, a mist of high-polymer agent having a natural component as the chief ingredient thereof, pressuring the wood material sprayed with the high polymer mist with the wood material aligned in the length direction thereof, and steam heating the wood material under a high-pressure environment to bond the adjacent wood chips together. A high-polymer agent containing tannin as a chief ingredient is used in one example. A high-polymer agent may be applied on the wood material. The method preferably further includes a curing step for cooling the wood material continuously in the high pressure environment to room temperatures using one of air cooling and natural cooling subsequent to the steam heating step for steam heating the wood material under the high-pressure environment to bond the adjacent wood chips together.
Description
technical field [0001] The present invention relates to the technology of utilizing conventionally unnecessary wood such as waste wood and thinned wood, and processing it into large-section wood, and particularly relates to the technology of producing regenerated wood without using harmful components for binders. Background technique [0002] Wood is a natural material that can be widely used in construction, interior decoration, etc., but due to the increase in its use, natural wood is gradually exhausted. Moreover, due to deforestation and unplanned afforestation, not only the resources are reduced, but also an important cause of the deterioration of the global environment. On the other hand, with the improvement of living standards, a large amount of waste wood is produced, but if it is not effectively utilized and only stays on incineration, it will cause a waste of resources. Moreover, although the reuse of thinned timber is advocated, its utilization range is narrow, ...
