    Method of producing a porous metal using clay particles
    [12] The present invention relates to a method for producing multifunctional porous metal having excellent mechanical properties, thermal properties, acoustic properties, energy absorbing properties, etc. using low cost and environmentally friendly ocher particles.
    [13] Lightweight transportation equipment, noise reduction, vibration absorption, shock absorption, and electromagnetic shielding in accordance with the improvement of living standard, the advancement of industry and the development of knowledge industry. The demand for environmental pollution prevention is a global trend. In response to these demands, porous metal materials have been developed in various ways.
    [14] The method of manufacturing porous metal material developed so far includes powder molding technology, molten metal bubble generation technology, casting technology and sintering technology, but all of these technologies have high cost and low productivity.
    [15] First, the powder molding technique consists of mixing the metal powder and the foaming agent (TiH 2, etc.), cold pressing powder of the mixed powder, hot forming of the green compact and foaming heat treatment of the molded body. However, the whole process requires a high cost, and since the ball mill is used in the mixing process of the metal powder and the foaming agent, the mixing time is long, which causes low productivity.
    [16] Molten metal bubble generation technology is a technology for producing porous metal by rotating impeller while injecting gas into molten metal to make bubbles and transporting them to the belt and cooling them. As it is not secured, it cannot be industrialized and remains at the research level.
    [17] Casting technology is a method of obtaining a porous metal product of high quality because it is difficult to control the size of the bubble and uniform distribution of the bubble by a method of obtaining a porous metal by dispersing the foaming agent in the molten metal to form bubbles and then solidify.
    [18] Casting technology using water-soluble salts can be produced at low cost and high speed, but there is a problem in cost recovery of salt.
    [19] Finally, the sintering technique is a technique for producing a porous metal by sintering metal particles, there is a limit to the distillation of metal and is not suitable for producing a large amount of continuous porous metal plate.
    [20] The present invention has been made to solve the conventional problems as described above, the object of the present invention is to prepare a cheap and environmentally friendly ocher particles using the excellent mechanical properties, thermal properties, acoustic properties, energy absorption properties, filtration The present invention provides a method for producing a multifunctional porous metal with even properties.

    [21] In order to achieve the above object, the present invention,
    [22] Mixing ocher and sand and kneading water to prepare ocher particles having various sizes and shapes (S1);
    [23] Preheating the ocher particles by a method of manufacturing sirutteok (S2);
    [24] After the step (S2), the step of injecting and infiltrating the molten metal into the space between the ocher particles by using a molten metal infiltration device to solidify (S3); And
    [25] It provides a method for producing a porous metal, comprising the step (S4) of removing the loess particles embedded in the metal.
    [26] In the step (S1), the composition of the ocher and sand is mixed so that the ratio of 7: 3 and the water is put into the amount of 5 to 10% of the ocher mixture, kneading, and when the dough is finished to form the kneaded ocher various sizes In the case of producing cubic particles, when the cubic particles are produced, a plate kneaded to a size of 1 to 10 mm thick, 1 to 10 mm wide and 1 to 10 mm long is cut and manufactured. On the contrary, when manufacturing spherical particles, ocher dough is cut out into holes having a diameter of 5 to 10 mm, cut into lengths of 5 to 10 mm, and then the ocher particles are manufactured in a spherical shape in a rotating cylinder.
    [27] In the step (S2), while installing the gravel 10-10 cm thick on the stove using a gas in the stove while heating the upper part of the mold by installing a vacuum pump for forcibly sucking the heat through the hole in the bottom of the mold ocher particles in the mold Preheated by Sirutteok manufacturing method. At this time, the preheating temperature is the same temperature as the melting point of the porous metal material.
    [28] In the step (S3), the mold containing the preheated ocher particles is placed on a vacuum seat, and the molten metal in the mold is forced into the space between the ocher particles through the salt seat to coagulate.
    [29] In the step (S4), the loess particles are embedded by destroying the loess particles with a high pressure sand blast (sand blast).
    [30] As mentioned above, according to the present invention, cubic or spherical ocher particles are prepared and preheated, molten metal is injected into the space between the preheated ocher particles, infiltrated and coagulated, and the ocher particles embedded in the metal To remove the porous metal.
    [31] Hereinafter, a method of manufacturing a porous metal according to the present invention will be described in detail with reference to the accompanying drawings.
    [32] The present invention is to provide an environment-friendly, recyclable, low cost, high productivity that conventional porous metal product manufacturing technology does not have, and to provide a technology that can mass-produce high-quality multifunctional metal products.
    [33] Ocher (Al 2 O 3 , 2SiO 2 , 2H 2 O), which is a material of ocher particles for producing porous metals according to the present invention, is an environmentally friendly material having an effect of toxin removal, degrading power, and purification.
    [34] In order to obtain ocher particles suitable for producing a porous metal using such ocher, first, ocher is mixed with sand (SiO 2 ) in a ratio of 7 to 3 and kneaded with water. At this time, water is added in an amount of up to 5 to 10% of the ocher mixture. In order to break up ocher particles, it is most effective when the ratio of loess to sand is 7 to 3.
    [35] When the dough is finished, it is molded into various shapes and sizes. One method is to make it thin and wide like a noodle mill, and then cut it into thicknesses of 1 to 10 mm, 1 to 10 mm and 1 to 10 mm in length to dry naturally. The cubic loess particles as described above are prepared. Cubic ocher particles are used to make irregular porous metals.
    [36] On the contrary, the kneaded ocher is put into a noodle frame and pressed to be 3-10 mm in diameter to be pushed out and put into a rotating barrel cut at regular intervals of 3-20 mm to produce spherical ocher particles as shown in FIG.
    [37] When manufactured by the above method, it can produce about 1-2 tons of cubic and spherical ocher particles for the production of porous metal at low cost and high speed production, and there is no environmental pollution.
    [38] 2 is a view schematically showing the structure of an ocher particle preheating device for preheating the ocher particles thus prepared.
    [39] Referring to FIG. 2, the ocher particle preheating apparatus 10 according to the present invention mainly includes a mold 12, a gravel layer 14, an oven 16, and a hot air suction pump 18. Holes are uniformly drilled in the bottom 11 of the mold 12, and a gravel layer 14 is disposed between the oven 16 and the bottom 11 of the mold 12. At this time, the diameter of the gravel constituting the gravel layer 14 is 3-6 cm and the thickness of the gravel layer 14 is 10-25 cm. The hot air suction pump 18 is installed to interlock with the upper portion of the mold 12.
    [40] In order to preheat the ocher particles using the ocher particle preheater 10 having such a structure, first the ocher particles Y are charged into the mold 12 and the gravel S is loaded thereon, and then the mold 12 is loaded. Place it on the oven (16).
    [41] In this state, when the burner 13 disposed in the oven 16 is operated, the gravel layer 14 is heated by the heat from the burner 13, at which time the hot suction pump 18 is operated to operate the gravel layer 14. The incoming heat is forced to convection between the ocher particles (Y) to preheat the ocher particles. The preheating temperature at this time is set to the same temperature as the melting point of the porous metal material.
    [42] Figure 3 schematically shows a device for infiltrating molten metal into the preheated ocher particles.
    [43] Referring to FIG. 3, the molten metal penetrating device 20 according to the present invention includes a mold 12 containing preheated ocher particles, a vacuum seat 22 disposed below the mold 12, and a vacuum seat 22. It consists of a suction pump 24 arranged to communicate. As the material of the molten metal, metals such as Al alloy, Al scrap, Zn alloy, Zn scrap, lead alloy, lead scrap, copper alloy, copper scrap, tin alloy and tin scrap are used.
    [44] In order to inject molten metal into the space of the ocher particles by using the molten metal penetrating device 20 having such a structure, first the ocher particles so that the ocher particles Y entrapped in the mold 12 do not float by the molten metal M. 5 ~ 10 ㎝ thick gravel (S) is put in the top so that evenly injected with the money between the gravel particles. At this time, the gravel (S) may be chopped in advance in the preheating step of the ocher particles (Y), as shown in FIG. In addition, in order to prevent the flow of the molten metal into the hole drilled in the bottom of the mold 11 is provided ocher particles or salt seat 26 between the mold bottom 11 and the vacuum seat (22).
    [45] In this state, by operating the vacuum suction pump 24 connected to the vacuum seat 22 so that the solvent M penetrates into the space between the ocher particles Y, the ocher particles Y are uniformly distributed. Permeate through) and solidify.
    [46] Finally, the ocher particles are taken out of the mold, cut to a certain size, and then subjected to a high pressure sand blast, the ocher particles are broken out of the metal. The ocher powder obtained here is used again to prepare ocher particles.
    [47] When the porous metal product is manufactured by the method of the present invention as mentioned above, the cost of ocher and sand used as a pore agent is low and the recycling cost is low, thereby reducing the manufacturing cost. In addition, it is environmentally friendly and can freely control the shape and size of the pores.
    [48] In addition, the use of gas and gravel as a method of preheating ocher particles enables fast and low cost of preheating, resulting in high-speed production of porous metal at low cost. In addition, metals used in the manufacture of porous metal products can be recycled into metals such as Al alloys, Al scraps, Zn alloys, Zn scraps, lead alloys, lead scraps, copper alloys, copper scraps, tin alloys and tin scraps. Combining particles and metals costs less and speeds up production. In addition, low-cost, high-speed production is possible because the vacuum pump accelerates the penetration of molten metal. In addition, the high-speed removal of the loess particles embedded in the metal by sand blast is possible without the environmental pollution as well as low-cost, high-speed mass production.
    [49] In particular, the porous metal product produced by the present invention is light weight, high strength, excellent sound absorption effect, filter effect, energy absorption effect and aesthetic effect can be applied to various applications.
    [50] Although the above has been described with reference to a preferred embodiment of the present invention, those skilled in the art will be able to variously modify and change the present invention without departing from the spirit and scope of the invention described in the claims below. It will be appreciated.
