Since the present invention uses bamboo having a very right growth cycle, it can be a great help for the conservation of forest resources, that is, wood. Above all, the cell structure of bamboo is very dense and strong, so it has excellent wear resistance and processability, and elasticity. Low warpage has a low effect, as well as physical properties such as antibacterial, anti-mildew, heat insulation and moisture-proof, heat retention, deodorization, etc. are very excellent. In addition, it is possible to manufacture environmentally friendly natural bamboo flooring material by removing formaldehyde, which is a harmful substance that occurs after adhering bamboo bamboo pieces to each other during hot press through press, and to secure mass production and productivity by manufacturing using multi-stage press. That has an important advantage.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings and examples.

1 is a view showing a process for producing an eco-friendly bamboo wood according to the present invention.

Referring to FIG. 1, in order to manufacture an eco-friendly bamboo wood, first, selecting 4 to 6 year old natural bamboo, bamboo cutting step of equally dividing the selected bamboo in the fiber direction, and the cut bamboo 150 ℃ high temperature and high pressure Sterilizing bamboo by carbonization stabilization and high frequency drying process, laminating bamboo using laminated mold immobilization compression technology, and processing bamboo by cutting, planing, sanding and painting process for each application Is made of.

Specifically, in the present invention, the bamboo is cut horizontally and vertically and put into a roller press to be manufactured in a bamboo sea state, wherein the bamboo sea state is a state in which the bamboo is finely divided in the longitudinal direction. This means that the tissue of the bamboo is in a disintegrated state so that it is easier to remove unnecessary tissue in the disinfection step. The unnecessary tissue means sugars, moisture, cellulose, or the like contained in bamboo.

Next, the disinfection step refers to a process of putting bamboo in a bamboo-sealed state into a sealed dry distillation apparatus and injecting steam, heating and pressing at a temperature of 150 to 160 ° C. at a temperature of 150 to 160 ° C. at about 5 atm. By removing the fragile and unnecessary tissues of bamboo such as sugar, moisture, cellulose, etc. in the bamboo tissue by high pressure and high temperature, it will have better strength, elasticity, processability and the like when molded into the structural material of the present invention.

In addition, to prevent the damage to the structural material of the present invention by blocking the source of the food itself of bees and fungi parasitic on bamboo.

The dry distillation high pressure device preferably uses an autoclave (second type pressure vessel), and when the heating temperature is 156 ° C. or less, it is difficult to remove unnecessary tissue in the bamboo tissue, and when it is 160 ° C. or more, carbonization proceeds. Bamboo loses its physical properties. Therefore, the most preferable temperature is 156-160 degreeC.

If the heating time is also less than 1 hour is too short time to remove the unnecessary tissue in the bamboo tissue, if more than 6 hours is already in the state of removing the unnecessary tissue of the bamboo tissue any more time is meaningless.

The sterilized bamboo sea bamboo is placed in a mold and stacked vertically and horizontally, because bamboos in the bamboo sea are only vulnerable in other directions. When the laminated bamboo is heated and pressurized with a heat press, it is formed into a structural material.

Finally, it is possible to use eco-friendly bamboo wood that does not emit harmful substances through the step of processing the bamboo molded for various uses.

Bamboo wood of the present invention manufactured as described above is excellent in impact resistance, compressibility, fire resistance, elasticity, etc., even if used as a structural material has no problem, and has much superior advantages to impact resistance, compression, fire resistance, and destruction of existing wood structural materials.

In addition, the eco-friendly bamboo wood according to the present invention is the benjokinone and acetic acid that has a bactericidal property of the components of the bamboo as it is, as a result of which the structural material itself has antibacterial properties against ticks and bacterial fungi, The porosity has the effect of adsorbing harmful chemicals including formaldehyde, as well as the deodorizing effect.

The bamboo used in the present invention may be any bamboo, but it is preferable to use a bamboo shoot (bamboo sundae) which is widely cultivated and has many active ingredients.

FIG. 2 is a cross-sectional view of the bamboo veneer compacted according to the present invention, in which bamboo bamboo pieces 11 are thermally laminated with a hot press to form a bamboo veneer 10. In addition, bamboo bamboo pieces 11 may be thermally laminated to form a bamboo end plate 10.

Such condensed bamboo usually has an impact strength of about 80 cm in which objects can fall in everyday life.
