The natural mineral mixtures VII and VII shown in Tables 2 and 3 may be used alone or in combination at each stage.

Next, a method for producing a functional bamboo floorboard according to the present invention will be described step by step.

[1] preparation of solid wood

The 6-year-old bamboo is harvested and stored in the shade for 30 days to remove moisture. This is to prevent warpage and maintain the original components of the bamboo logs, and to prevent color deterioration.

Subsequently, the solid wood member was cut into pieces with a width of 20 to 25 mm and a thickness of 3 to 5 mm, cut and then dried for 72 hours to maintain the original color and pattern of the bamboo. By trimming, the wood solid wood member is classified into light and dark colors by concentration.

[2] steaming

The surface finishing bamboo wood member is subjected to the steaming process, in place of the water required in the steaming process, water and; Incombustibles; And a mixed aqueous solution consisting of natural minerals.

The incombustibles and natural minerals are in powder form, the incombustibles are mixed at a ratio of 3 to 8% by volume with respect to water, and the natural minerals are mixed at a ratio of 5 to 20% by weight with respect to water. 1,200 ~ 5,000 mesh is used.

After impregnating the bamboo wood member carved as described above in the aqueous solution and steamed at high temperature and high pressure to carbonize. This is to remove various impurities in the steaming process and to increase the antibacterial property, and to allow the non-combustible materials and natural minerals to penetrate into the bamboo bubbles to have the ability to generate non-combustible and negative ions.

[3] aggregation (adhesion)

Subsequently, the bamboo wood member, which has undergone the steaming process, is dried and bonded at high temperature to be aggregated, but in order to remove fire safety and environmental hormones, a non-combustible substance and a natural mineral of 1,200 to 5,000 mesh are mixed and bonded to the bonding adhesive.

In other words, non-combustible materials are mixed at a ratio of 3 to 8% by volume with respect to the bonding adhesive, and natural minerals are mixed and diluted at a ratio of 5 to 20% by weight with respect to the adhesive, and then the mixed adhesive is made of solid wood. It is applied to a member, joined together in the form of a panel, and then compression molded at a high temperature for about 10 minutes in the same manner as in the case of producing a known aggregate wood.

At this time, the bonding adhesive is a known adhesive used in the process of collecting bamboo pieces.

In addition, the bamboo wood member is composed of the upper plate 10, the intermediate plate 20 and the lower plate 30, as shown in Figures 2 and 3, the upper plate and the intermediate plate and lower plate to cross each other in the horizontal and vertical directions Lamination to prevent warpage or bending after construction of the floorboard according to the invention.
