Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a flow chart showing a building plate manufacturing method using eco-friendly volcanic stone according to the present invention.

In the first step of the building plate manufacturing method using eco-friendly volcanic stone according to the present invention, the volcanic stone is pulverized into a powder having a size of 3 mm to 5 mm. A feature of the present invention is to directly make the volcanic stone itself, the particle size of the volcanic stone is very important in the process of grinding the volcanic stone. In order to make a plate, the stirring and heating process should be included. When the volcanic stone is crushed to 2 mm or less, the volcanic stone is preferably crushed to a size of at least 3 mm since the useful components contained in the volcanic stone are degraded during the stirring and heating process.

However, when the size of the volcanic stone powder exceeds 5mm, the particles of the volcanic stone are large during molding of the sheet for the purpose of the present invention, and defects occur during molding. Therefore, it can be said that the optimum condition is to crush the volcanic stone to the size of 3mm to 5mm in order to produce the building plate.

In the second step according to the present invention, the pearlite and vermiculite are pulverized into powders of 2 mm or less, respectively, and the pearlite is pulverized and then heated to 800 ° C. to 1200 ° C. to be peeled and expanded 12 to 15 times, and the vermiculite is 600 ° C. to 700 ° C. Heated to 7-10 times for exfoliation and expansion. The pearlite generally used for building has a heat insulating and sound absorption effect, and vermiculite is a material already widely known to have a heat insulating and warming effect, so that the pearlite according to the present invention can have a basic function for using a building plate. And the vermiculite is peeled and expanded in the form of powder of 2 mm or less, and the pearlite is heated to 800 ° C to 1200 ° C and peeled and expanded 12 to 15 times, and the vermiculite is heated to 600 ° C to 700 ° C and peeled and expanded 7 to 10 times.

In the third step according to the present invention, the pulverized volcanic stone, peeled-expanded expanded pearlite, vermiculite powder, mica and tourmaline powder are mixed and heated with stirring for 2 hours while maintaining at 300 ° C to 500 ° C in a vacuum rotary furnace. At this time, 40% to 60% by weight of the pulverized volcanic stone, 10% to 15% by weight of exfoliated expanded pearlite, 10% to 15% by weight of vermiculite and 10% to 15% by weight of mica emitting far infrared rays, tourmaline 10 Mix the powder by weight to 15% by weight, but the pearlite, vermiculite, mica and tourmaline are mixed in a ratio of 1: 1 to not exceed 100% by weight in total. Since the pulverized volcanic stones are only grains such as stone powder in the crushed state, pearlite and vermiculite must be mixed in order to be used as a building plate. In order to produce a plate using volcanic stone which is an object of the present invention, it is preferable to include a lot of volcanic stone itself.

However, in the present invention, the volcanic stone has a high porosity, but does not undergo a separate plastic processing step in order to maximize the useful effects of the volcanic stone and also includes a foaming process only for the volcanic stone. If plate is produced, raw material supply and mass production is impossible, and because volcanic stone has physical properties without viscosity itself, it is not possible to produce plate by crushing volcanic stone.

Therefore, in the present invention, it is preferable to exfoliate and expand the pearlite having the same chemical properties as the volcanic stone to expand and mix the volcanic stone and vermiculite having good water retention. In particular, the pulverized volcanic stone is preferably mixed with 40% by weight to 60% by weight in a range not exceeding 100% by weight of the mixture of pearlite, vermiculite, mica and tourmaline. When mixed with less than 40% by weight of the total 100% by weight of pulverized pearlite and vermiculite, the intrinsic ability of releasing substances beneficial to the human body such as negative ions and far infrared rays inherent to volcanic stones is weakened. If the weight exceeds 60% by weight of 100% by weight of the building plate strength may be a crack or cracking edge after the final molding may cause problems.

In the fourth step according to the present invention, the porous mixture powder is foamed by exposing the mixed powder heated and stirred evenly in the atmosphere in the stirring / heating process to the atmosphere in an instant. In the fifth step according to the present invention, the foamed mixed powder is 80 wt. %, 10% by weight of vegetable wood fiber, such as palm fiber, pulp fiber, and 10% by weight of Portland cement.

Subsequently, in the sixth step according to the present invention, 5% by weight of aluminum hydroxide (A (OH) ₃ ), 5% by weight of carbon, 25% by weight of gemstone foam powder composed of 130 mesh or more, 25% by weight of vesicle powder and 50% by weight of water. Mixing to continuously heat at 60 ~ 70 ℃ to produce an inorganic liquid excellent in water resistance, sound insulation, adhesion and flame retardant. At this time, the aluminum hydroxide used in the present invention has a specific gravity of 2.423, which is naturally present as a gibbsite and a diaspore. When ammonia water is added to an aqueous solution of aluminum, it is formed by precipitation in a white colloidal form. The loss of one water molecule is an amphoteric hydroxide, which reacts with alkali to form aluminate and reacts with acid to form the salt.

Next, step 7 according to the present invention is stirred and kneaded by adding 60% by weight of the mixture prepared in step 5, 30% by weight of the inorganic liquid prepared in step 6 and 10% by weight of an inorganic adhesive such as water-soluble epoxy, etc. In step 8 of the present invention, the mixture is introduced into a molding mold, and the molded body is dried with hot air at 120 to 140 ° C. on a conveyor while applying a pressure of 5 kg per cm 3.

In the final nine step according to the present invention by cutting the dried molded body from the molding mold to cut to a predetermined length by using expandable minerals such as volcanic stone, pearlite, vermiculite, etc. The top panel 10 of the building panel 100 manufactured as described above may be manufactured as described above, and together with volcanic stone, pearlite and vermiculite, an anion and far infrared emission beneficial to the human body, as well as an antimicrobial action, may be mixed with mica and tourmaline. Due to the construction, it is possible to exert powerful antibacterial action against germs such as swine flu or bird flu, which is deadly and contagious to humans floating in the air in the indoor construction state, thus greatly increasing the reliability of the building panel 100. It can be improved.
