3 and 4 will be described a functional plywood generating the anion of the present invention.

As shown in Figs. 3 and 4, the functional plywood that generates negative ions includes a plurality of thin plates 1a, 1b, and 1c cut out of thin wood so that the fiber directions are orthogonal to each other. It consists of functional adhesive layers 4 and 4 'formed on both sides with a functional adhesive, and a back plate 2 and a back plate 3 adhered to the functional adhesive layers 4 and 4', respectively.

The referee 1, the sign plate 2, and the back plate 3 are the same as those conventionally used for plywood.

The functional adhesive layer (4, 4 ') is formed of a functional adhesive having a sterilizing function, a pesticidal function and a function that emits far infrared rays, the functional adhesive is 4 to 7% by weight of active ocher powder and 1 to 3% by weight of charcoal powder It consists of 10 to 15% by weight of the mineral powder and 75 to 85% by weight of the adhesive, or 10 to 15% by weight of the mineral powder, 10 to 15% by weight of the wood vinegar and 70 to 80% by weight of the adhesive.

The active ocher powder emits far-infrared rays, and then pure ocher is heated at a high temperature of 800 to 900 ° C. to be fired at high temperature, and then pulverized by quenching using water or air to have an average particle size of 600 to 1000 mesh. . By heating the high temperature of the loess as described above, the microorganisms present in the loess are removed to suppress the growth of mold and insects after the papering.

The charcoal powder is pulverized in the pulverizing the solidified charcoal produced by carbonizing wood using a charcoal powder having a particle size of 350 ± 50 mesh through a strainer.

If the particle size of the 350 ± 50 mesh is larger than this, the coating film may be damaged by the breakage of the particles even after a light external impact after application, and if the particles are too small, the porosity of the charcoal characteristics are damaged.

The mineral powder may be used by selecting any one of serpentine, zeolite, tourmaline, monazite, jade, seven stones, and elvan, which are known to generate anions, or two or more powders may be mixed.

The mineral powder is pulverized in a pulverizing device and has a mean particle size of 600 ~ 800 mesh through the strainer.

When the particle size of the mineral powder is 600 or less, the coating performance is lowered, and it is difficult to apply the coating evenly. When the particle size of the mineral powder is 800 or more, the coating performance is not significantly improved as compared to the grinding process, which is inefficient.

The adhesive may be casein, viscose, glutamine adhesive or the like.

FIG. 5 is a cross-sectional view of a functional plywood generating anion, which is another embodiment of the present invention. The functional material penetrates one or both sides of the judgment 1 to form the functional material penetrating layers 5 and 5 '. The functional adhesive layers 4 and 4 'are formed by applying the above-mentioned functional adhesive again to the referee 1 on which the functional material penetration layers 5 and 5' are formed, and the functional adhesive layers 4 and 4 'are formed. The top plate 2 and the back plate 3 are bonded to each other to form them.

The functional material forming the functional material penetrating layer (5, 5 ') has the same function as a functional adhesive, it is used to select any one of serpentine, zeolite, tourmaline, monazite, jade, seven stones, elvan powder Or it consists of 40 to 60% by weight of the mineral powder generating anion having an average particle size of 600 ~ 800 mesh mixed with two or more powders and 40 to 60% by weight of the wood vinegar.

The functional material penetrating layer (5, 5 ') is formed by immersing the functional material into the functional material consisting of mineral powder and wood vinegar solution (soak) to penetrate the functional material into the functional object (1), or judge the functional material ( 1) It is formed by penetrating the surface several times.

However, the functional material penetrating layers 5 and 5 'may be formed by adding a functional material composed of the mineral powder and wood vinegar solution in the preparation of the judgment 1.

When the functional material is applied and penetrated to form the functional material penetrating layers 5 and 5 ', the coating and drying are repeated at least twice.

The functional plywood that generates negative ions may form a functional adhesive layer 4 by applying a functional adhesive only to one surface to which the plate 2 is adhered on both sides of the referee 1, or may be formed on both sides of the referee 1. Only the functional material penetration layer 5 formed by penetrating the functional material 5 and the functional adhesive layer 4 formed by applying the functional adhesive may be formed on only one surface to which 2) is bonded, or the plate on both sides of the referee 1. The functional material penetrating layer 4 formed by penetrating the functional material on only one surface to which (2) is bonded may be formed, and the functional adhesive layers 4 and 4 'formed by applying a functional adhesive on both sides may be formed.

Figure 6 is a simplified illustration of the steps of the manufacturing method of the functional plywood generating anion of the present invention, the step of forming a functional material penetration layer by penetrating the functional material on one or both sides of the judgment (S1), and Step (S2) after the step (S1) to form a functional adhesive layer by applying a functional adhesive to the judgment (1) comprising a functional material penetration layer, and after the step (S2) attaching the plate and the back plate to the functional adhesive layer ( S3).

As shown in FIG. 5, the functional material was penetrated three times on both sides of the judgment 1 to form a functional material penetration layer, and a functional adhesive functional adhesive was applied to form a functional adhesive layer.

The following experiments were carried out with the functional plywood prepared in Examples 1, 2 and 3 and a general plywood (comparative example) which is commercially available.

Experimental Example 1

Brushes for applying a fungal strain of a mixed strain of Aspergillus niger ATCC9542 and Penicillium pinophilum ATCC 11797 and Chaetotomium globosum ATCC 6205 were applied to each specimen. After the coating was evenly applied, each specimen was visually observed for mold development at intervals of 1, 2, 3 and 4 weeks under the same conditions of 30 ° C. and 80% humidity.

1 week later after 2 weeks 3 weeks later 4 weeks later Example 1 0% 2% 3% 3% Example 2 0% One% One% One% Example 3 0% 0% 0% 0% Comparative example 0% 10% 24% 50%

As shown in Table 1 above, mold propagation occurs in commercial plywood on the market, and in the case of the functional plywood manufactured according to the present invention, only partially occurs and no longer propagates. Plywood has bactericidal and insecticidal functions, so it can be seen that mold does not occur at all or does not grow well even under conditions favorable for mold development.
