At this time, some of the raw materials are selected and mixed according to the intended use. Thereafter, when the filler is mixed with water, an osmotic agent, and a blowing agent in the inorganic mineral fiber, the mixture reacts with each other to form a slime-like one-dimensional material. Here, instead of making the non-toxic inorganic mineral fiber raw material into a fiber, it may be used in the form of a powder or may be used as a one-dimensional material with only the filler without using it. In this case, the strength of the product is lowered, so choose carefully.

Here, when mixing the one-dimensional material, it is also considered to improve the properties of the raw material by adding a caking agent, dust inhibitor, water repellent, dispersant, emulsifier, softener, waterproofing agent. At this time, the combined weight of all the additives added is such that the mixing ratio of the total weight is 5% or less. In this case, the additive is selected and added according to the characteristics of the raw material and the product.

In addition, at least one or more of natural or artificial silicate minerals such as other stone powder, fly ash, blast furnace slag, sodium silicate and magnesium silicate of the one-dimensional material and the similar composition are added to 10% or less to be used as a substitute for the one-dimensional material. It is also worth considering.

In the preparation process, it is preferable to add a commercial osmotic agent to process the one-dimensional material into the mucus to homogenize and increase the reactivity.

In addition, the foaming agent may be further added in the preparation process so that pores are formed in the molding process to be described later, thereby reducing the weight of the product and improving sound insulation insulation. The addition of foaming agent and the expansion ratio should be adjusted according to the use and characteristics of the product.

In the preparation process, a liquid obtained by diluting or dissolving an organic or inorganic flame retardant or flame retardant, or a natural or artificial inorganic mineral is dissolved or ultra-fine powdered with water to use a liquid mixed with water instead of water to mix raw materials. It is also possible to increase the fire resistance of the product.

Next, the mixing process will be described. The mixing process is to prepare a two-dimensional material by mixing a reaction agent such as calcium carbonate, calcium silicate, calcium oxide, magnesium oxide, magnesium chloride, magnesium sulfate, iron oxide, aluminum oxide, silicon dioxide, zirconium dioxide, calcium hydroxide, aluminum hydroxide and the like It is a process of preparing three-dimensional material by mixing and reacting with one-dimensional material. In this case, the mixture is stirred by using water contained in the one-dimensional material without adding water for mixing. However, if necessary, an appropriate amount of water may be further added to facilitate stirring.

In this case, when the mixing of the one-dimensional material and the two-dimensional material is accelerated the reaction to improve the curing performance of the hardening reaction accelerator or coarse, quickeners, enhancers, thickeners, adhesives, air entrainer, antifoaming agent, water reducing agent, waterproofing agent, etc. Consider adding less than%.

In addition, when mixing the one-dimensional material and two-dimensional material, cement (portland, mixed portland, special portland), resin (non-toxic resin (water-based epoxy, EVA, polyester and acrylic resin), plubber (thermoplastic rubber), Arabia Rubber, latex-based), metal oxides (zinc oxide, titanium dioxide) or at least 10% of natural or artificial minerals containing 70% or more of the two-dimensional material as the main component It is also worth considering using it as a substitute for ash.

In addition, in the mixing process, to improve strength, plant fibers such as nonwoven fabrics or sawdust, pastor, wood chips, palm fibers, palm fiber cotton stems, bamboo, herbaceous plants, nuts and shells, etc. In addition, at least one or more materials of a metal fiber, such as aluminum mesh, or a mineral fiber textile woven in various inorganic mineral fibers may be considered.

Here, in the case of the plant fiber, it may be considered to use the mineralized it. Mineralization of the plant fiber is to penetrate the hardening agent prepared by mixing organic or inorganic flame retardant or flame retardant and mineral material into the plant fiber and to form a film of mineral material on the surface of the plant fiber fire, fire, non-toxic, water resistance It is a method to improve weather resistance, corrosion resistance, chemical resistance and deformation resistance.

It is also worth considering further improving the adhesive strength by further mixing the non-toxic adhesive with fire resistance during the mixing process.

Next, the molding process will be described. The molding process is a process of molding the three-dimensional material into a desired shape. Since the three-dimensional material is a clay state, the shape is created in various ways such as passing through a mold, a press, and a rotating roller. When the blowing agent is added, the three-dimensional material is added to form pores therein, and then the pressure is not applied or the pressure is controlled and the pressure is increased to increase the strength and density. It is also worth considering to apply a large mold. In addition, it is also considered to shorten the molding time and promote foaming by heating and molding the three-dimensional material.

In the molding process, the surface may be roughened, polished or matte surface treated, or an intaglio or embossed pattern may be formed to improve sound absorption, adhesion, or aesthetics.

At this time, one or more of cloth, wallpaper, decoration sheet, sound absorbing material, heating material, aluminum foil, solid wood plate, synthetic wood sheet, stone tile, and synthetic stone tile may be attached to at least one surface of the molded product to increase decorative and functional properties.
