METHOD FOR MANUFACTURING BUILDING INTERIOR MATERIAL AND BUILDING INTERIOR MATERIAL}

The present invention relates to a method for manufacturing a building interior material and a building interior material. More specifically, it relates to a method for manufacturing a building interior material and a building interior material having a natural embossed surface using a gypsum mixture in which gypsum, vermiculite, and functional minerals are mixed.

With the emergence of eco-friendliness as one of the most important issues in interior materials for construction, the market and demand are rapidly moving to eco-friendly interior materials. In response to the demand for such eco-friendly building interior materials, a variety of building interior materials are obtained by mixing and molding gypsum, vermiculite, and minerals such as gelite and ocher.

Existing building interior products cannot be concluded because they are satisfactory in terms of strength, embossing, surface texture, gloss, and naturalness. Looking at the conventional products that are being produced, the strength of the product is low, and it lacks the similarity with the natural stone, which is a characteristic that the product should possess, and the various colors and the smooth natural surface are less complete, and it is likely to break and become contaminated. The feeling that seems to be appears clearly.

Most of the existing products in Korea seem to be made as if the surface of the product is fragile and the natural color does not appear, making the feeling and monotony of contamination easy. The reason is that when the gypsum mixture of gypsum, vermiculite, a small amount of gelite and water are stirred and injected into the mold, the heavy gypsum sits underneath and the lightweight foamed vermiculite, which is about 1/20 of the gypsum mass, has a light mass. This is because the surface of the product is hidden by natural plaster (embo), which is an advantage of vermiculite, and the natural color is hidden by heavy plaster. As a result, the existing products have a monotonous appearance and a result that shows only gypsum powder that is easily contaminated.

In the case of molding a building interior material by injecting a gypsum mixture containing a mixture of gypsum, vermiculite, and functional mineral into water and stirring it into a mold, sufficiently express the carved patterns (irregularities) on the bottom surface of the mold that becomes the surface layer of the final product. In order to increase the mixing ratio, which is the mixing ratio of water with gypsum, the dough is made to flow and injected into the mold. In this case, because the mass of the gypsum is about 20 times larger than that of vermiculite, the surface layer of the final product can sufficiently exhibit the pattern, but since the plaster is settled in the mold, the surface layer of the final product is covered with plaster all over, resulting in a lack of natural stone feel. It has the disadvantage of being weak due to its weak strength and not natural at all.

Accordingly, it is necessary to form a natural embossing on the surface of the product while giving the product high strength to give a natural stone-like feel. Furthermore, on the one hand, it may be necessary to have smoothness and subtle glow due to the softness and semi-gloss of the product surface, or to further express high-quality colors such as solid to multicolor mixing.

In the present invention, in order to solve this problem, to control the mixing ratio of the gypsum mixture and water, and solved through particle sedimentation through compression when injecting the mold, and furthermore, to express the color through the stirring of water containing (Press) pigment .

[Building interior material manufacturing method]

First, a method of manufacturing a building interior material according to one aspect of the present invention will be described with reference to the drawings. At this time, reference will be made to the drawings of the building interior material shown in FIG. 6 as well as the manufacturing method shown in FIGS. 1 to 5.

It is an overall flow chart showing a method of manufacturing a building interior material according to.

In addition, Figure 6 is a cross-sectional view schematically showing a cross-section of a building interior material according to an embodiment of the present invention.

1 to 5, the method for manufacturing a building interior material according to one example is a primary stirring step (S100, S1100, S2100, S3100), injection and compression steps (S200, S1200, S3200), reinforcement step (S300), Secondary stirring step (4300), residual molding step (S500), and demolding and drying step (S600). Referring to FIG. 5, the method for manufacturing a building interior material according to an example may further include a surface treatment step (S700 ).

First, in the first stirring step (S100, S1100, S2100, S3100), gypsum powder 70 ~ 80wt%, vermiculite powder 10 ~ 25wt% and functional mineral powder 5 ~ 10wt% mixed first gypsum mixture and the first stirring The water is first stirred in a volume ratio ranging from 4:1 to 7:3. In the injection and compression steps (S200, S1200, S3200), the first stirred mixture stirred in the first stirring step (S100, S1100, S2100, S3100) is partially injected into the prepared mold and compressed to obtain granular particles in the first stirred mixture To settle to the bottom surface to form an embossed surface. In the reinforcing step (S300), a strength reinforcing material is applied to the upper portion of the first stirring mixture injected into the mold. For example, the reinforcement step (S300) may be performed after compression in the injection and compression steps (S200, S1200, S3200), or may be performed before compression after injection. In the next second stirring step (S400), the second gypsum mixture and the second stirring water mixed at a ratio of 80 to 90 wt% of gypsum powder and 10 to 20 wt% of vermiculite powder are prepared at a volume ratio of 7:3 to 3:2. 1 Stir more secondaryly than the stirred mixture. In the remaining molding step (S500), the second stirring mixture stirred in the second stirring step (S400) is injected into the upper part of the mold's strength reinforcing material to fill the predetermined remaining portion of the mold and semi-dry. In the demoulding and drying step (S600), the mold is demolded in a semi-dry state and dried in a drying furnace.

Hereinafter, with reference to FIGS. 1 to 5, the primary stirring step (S100, S1100, S2100, S3100), injection and compression steps (S200, S1200, S3200), reinforcement step (S300), secondary stirring step (4300) , Residual molding step (S500), demolding and drying step (S600), and the surface treatment step (S700) in detail in order.

1st stirring step (S100, S1100, S2100, S3100)

The primary stirring steps (S100, S1100, S2100, and S3100) will be described with reference to FIGS. 1 to 5. In the first stirring step (S100, S1100, S2100, S3100), the first gypsum mixture mixed with the gypsum powder, vermiculite powder, and functional mineral powder and the first stirring water are first stirred. At this time, the first gypsum mixture is mixed in a proportion of gypsum powder 70 ~ 80wt%, vermiculite powder 10 ~ 25wt% and functional mineral powder 5 ~ 10wt%. When mixed with water, the gypsum powder hardens by hydration and becomes a congestion. When the gypsum powder is higher than 80wt%, the content of the vermiculite powder and/or functional mineral powder is reduced, making it difficult to sufficiently exhibit the excellent properties of the vermiculite powder and the functionality of the functional mineral, and the content of the plaster powder that acts as a condensate by hydration reaction. When it is lowered below 70 wt%, it may be difficult to sufficiently exert the strength of the building interior product. Accordingly, the content of the gypsum powder is set to 70 to 80 wt% and the content of the remaining vermiculite powder and functional powder is set to 20 to 30 wt%.

Vermiculite is porous and has good absorption ability, so it is widely used as a heat-resistant material and sound-insulating material. In addition, vermiculite expands when heated. Accordingly, when the vermiculite is heated and expanded, a material having a light weight and excellent porosity can be obtained. The vermiculite powder can be obtained by heating and expanding the vermiculite to form a powder, and accordingly, the vermiculite powder has excellent thermal insulation, sound insulation, and moisture-proof properties due to the continuous hollow layer caused by bubbles. For example, in the example of the present invention, expanded vermiculite powder with light weight insulation by powdering the expanded vermiculite is used. By using the expanded vermiculite powder having light weight insulation properties, a light weight heat insulation interior material can be realized.

The functional mineral powder is a functional mineral powder, and may be, for example, a powder having a mineral having any one or more functions such as antibacterial, far infrared, anion, moisture proof, heat insulation, sound insulation, purification, and adsorption. Examples of functional minerals include, but are not limited to, germanium-containing minerals, pearlite minerals, illite minerals, zeolite minerals, and the like.

For example, in one example, the functional mineral powder may be a gelite powder, a pearlite powder, or a mixed powder thereof. Gellite is an example of a germanium-containing mineral. Pearlite powder is light and excellent in porosity, so it has excellent properties of heat insulation, sound insulation, and moisture resistance, just like vermiculite.

In one example, the average particle size of the vermiculite powder in the first gypsum mixture mixed in the first stirring step (S100, S1100, S2100, S3100) is greater than the average particle size of the gypsum powder and functional mineral powder. For example, vermiculite powder may be about 1 to 3 mm, gypsum powder may be 1 mm or less, and functional mineral powder may be 1 mm or less. Accordingly, the particle size of the first agitation mixture in which the first gypsum mixture and the first agitation water are stirred can be maintained at about 1 to 4 mm.

Referring to FIGS. 1 to 5 again, in the first stirring step (S100, S1100, S2100, S3100), the first gypsum mixture and the first stirring water are first stirred at a volume ratio in the range of 4:1 to 7:3. do. The first stirring mixture with high viscosity is obtained according to the primary stirring. At this time, the higher the content of the gypsum powder in the first gypsum mixture, the higher the stirring rate of the first stirring water, and the lower the content of the gypsum powder, the lower the stirring rate of the first stirring water. For example, when the content of the gypsum powder is low and the stirring ratio of the first gypsum mixture and the first agitating water is increased, the mixture is diluted with stirring, thereby making it difficult to form embossing by particles of the first agitation mixture on the surface of the final product. It may be difficult to sufficiently maintain the strength of the final product. On the other hand, if the content of gypsum powder is high and the stirring ratio of the first gypsum mixture and the first agitating water is lowered, it is stirred too rapidly and hardened quickly, so process control in the manufacturing process may become difficult and furthermore, embossing of the final product The surface may not be smooth and may become rough.

In general, the conventional stirring method increases the coma ratio (mixing ratio of water to gypsum) and creates a dough state to flow so that it is injected into the mold. In the past, the coma rate was increased to sufficiently express the carved patterns (irregularities) on the bottom surface of the mold, which is the surface layer of the final product. In this case, because the mass of the gypsum is about 20 times larger than that of vermiculite, the surface layer of the final product can exhibit a sufficient pattern, but since the plaster subsides in the mold and the vermiculite with a small specific gravity and large particle size floats, the surface layer of the final product is all plaster It has the disadvantage that it does not feel like a natural stone because it is covered, and the strength is weak, so it is likely to break and is not natural at all.

As a means for solving this problem, the first gypsum mixture and the first agitation water are stirred when the first gypsum mixture and the first agitation water are stirred by properly maintaining the agitation ratio of the first gypsum mixture and the first agitation water. It is stirred at a volume ratio of 4:1 to 7:3 to lower the coma ratio than the conventional method to increase the solidity of gypsum, and as another problem solving means, pressure is applied as described below to apply particles of the first stirred mixture, For example, the embossing is formed on the surface so that the agitated particles having a large average particle size contact the bottom of the mold to give a natural stone-like feel. In the case of this method, since the mixing ratio is lower than that of the conventional method, the entirety of the partially agglomerated portion is not soft, but is continuously stirred using a hand or a mixer. It is made into particles of about 1 to 4 mm, which are as small as rice grains. In this case, when mixing the first stirring water, a spray may be used and stirred.

After the first stirring mixture obtained through this stirring process is injected into the mold in the injection and compression steps (S200, S1200, S3200) described below, the surface of the final product is formed through compression through roller press, vertical press, manual roller, etc. It is possible to implement natural embossing irregularities on the mold bottom and the contact surface portion to be further spread, and evenly spray water in advance on the mold bottom surface in the injection and compression steps (S1200, S3200), and then inject and compress the first stirring mixture to compress the mold bottom and contact surface. On the surface, a smooth, smooth surface like marble can be realized.

On the other hand, it should be noted that the curing in the first stirring step (S100, S1100, S2100, S3100) is fast because of a low coma. Depending on the curing speed, a retarder or the like can be used. On the other hand, since the coma ratio is low, the strength becomes strong. For example, referring to FIG. 2, in one example, the primary agitation may be performed by adding a retarder such that the weight ratio of the gypsum powder and the retarder is 100:1 to 5 in the first stirring step (S1100). If you want to slow or control the rate of hardening or setting of the plaster depending on the working speed, you can adjust the retarder. By adding an appropriate amount of the retarder, the curing or coagulation of the gypsum is delayed to overcome the problem of coagulation in the course of agitation, and can be naturally molded through injection and compression steps (S200, S1200, S3200) described later. For example, when 30 g of water is stirred in 100 g of gypsum, the delay of curing or condensation of gypsum can be slowed by approximately 25 minutes when mixing 2.5 g of retardant and approximately 40 minutes when mixing 5 g. Stirring can be performed. Adjustment of the curing or condensation rate by the retarder depends not only on the amount of the retardant added, but also on the gypsum content of the first gypsum mixture, the mixing ratio of water in the first stirred mixture, etc., and thus should be appropriately adjusted according to the embodiment. The configuration of primary agitation by adding a retarder in the primary agitation step (S1100) illustrated in FIG. 2 is not shown, but may be applied to the embodiments according to FIGS. 3 to 5.

Next, referring to Figures 3 to 4, look at the primary agitation step (S2100, S3100) further. FIG. 3 shows a process for coloring the upper layer of the final product (refer to reference numeral 100 in FIG. 6) in a single color, and FIG. 4 shows a process for allowing the upper layer 100 of the final product to be mixed and colored in multiple colors. .

3 and/or 4, in one example, the first stirring water in the primary stirring step (S2100, S3100) is colored water. The first gypsum mixture and the first stirring water to be used for stirring are prepared by coloring in a desired color. Injecting and compressing steps (S1200, S3200) of a first stirring mixture consisting of stirring particles of, for example, sesame to rice grain size of about 1 to 4 mm colored by stirring with colored first stirring water as shown in FIGS. 3 and/or 4 (S1200, S3200) ), evenly injected into the mold, and then compressed, the granules colored in the final result appear naturally on the surface layer. As shown in FIGS. 3 and/or 4, the coloring is performed during the stirring process, and although not shown, the water containing the pigment is sprayed into the mold with a spray or the like regardless of stirring, and the first stirring mixture is injected. Dyeing with a different feeling may also be implemented by the post-dye method.

Furthermore, one example will be described with reference to FIG. 4. At this time, according to the setting in the first stirring step (S3100), the first gypsum mixture is divided into a number, and the first agitation water is colored and divided into a plurality of colors to correspond to the proportion of the first gypsum mixture divided into a number of colors. It can be prepared and stirred for each color. Thereafter, in order to form a multi-colored product, a plurality of first agitation mixtures for each color stirred in the injection and compression step (S3200) described below may be mixed and injected into a mold. When various mixing colors are desired, the first agitation water used for the first agitation is prepared with a plurality of agitation dyeing waters containing various pigments, respectively, and the first gypsum mixtures distributed to correspond to the distribution ratio of the amount of water. The primary agitation may be randomly mixed in the mold injection process before or after the mold injection, which will be described later, or natural color artificial stone may be implemented or the colors may be arranged at regular intervals. Through this, it is possible to realize a surface such as natural marble, and embossing is alive on the surface of the product through pressurization, etc. in the injection and compression step (S3200), and semi-glossy luster is expressed. Can be produced. The result of this manufacturing method can feel a huge difference from those of the existing method.

Injection and compression steps (S200, S1200, S3200)

The injection and compression steps ((S200, S1200, S3200)) will be described with reference to FIGS. 1 to 5. In the injection and compression step ((S200, S1200, S3200)), the first stirred mixture stirred in the first stirring step (S100, S1100, S2100, S3100) is partially injected into the prepared mold and compressed to form a portion of the first stirred mixture. The grain particles settle to the bottom surface to form an embossed surface. For example, the first gypsum mixture and the first stirring mixture having a viscous mixture with the first stirring water are injected into the mold less than two-thirds of the time, and pressurized with a press or the like to apply the pressure to a height of about half of the mold. 1 Make a stirred mixed layer. Since the first stirred mixed layer has a low viscosity and high viscosity, it is not densely filled to the bottom of the mold, but by applying pressure with a press, the grain particles of the first stirred mixture settle down to the bottom of the mold and the bottom surface of the mold. An embossing structure may be formed at a contact surface portion in contact with the first stirring mixed layer formed to a height of about half of the mold, and then the upper layer 100 in the final product after curing. Roller press, vertical press, hot roller press, manual roller, etc. may be used to apply pressure, but are not limited thereto. At this time, the strength of the upper layer 100 of the final product is increased due to compression.

At this time, as the compression strength is properly adjusted, air bubbles (embossing) naturally appear on the surface of the surface of the contact surface with the mold bottom, and when fresh water is evenly sprayed on the bottom surface of the mold as described below, it is pressed according to the pressure and contacts with water on the contact surface. And similar to marble, the surface texture can be expressed smoothly. For example, when the first stirred mixture having small particles such as millet or rice grains of about 1 to 4 mm, which is primarily stirred, is injected into a mold and compressed with a roller or press, for example, small grains such as dried rice grains according to compressive strength Since particles, for example, stir particles of a large vermiculite powder having an average particle size are pressed against the bottom of the surface layer, the grains are alive and natural embossing can be seen.

For example, in one example, when the average particle size of the first gypsum mixture has the largest vermiculite powder, the agitated particles of the vermiculite powder in the first stir mixture are compressed by compression in the injection and compression steps (S200, S1200, S3200). The embossing surface can be formed by sedimentation with a surface. If the first stirring mixture is left in the mold, the surface of the final product may become rough due to the viscosity of the first stirring mixture, and the mass of the gypsum is about 20 times larger than that of vermiculite. Most of them are covered by gypsum hydrate, but by forcibly compressing as in this step, stir particles of a large average particle size of vermiculite powder settle to the bottom to form an embossed surface, and at the same time interact with water pre-sprayed on the mold bottom surface. A smooth surface can be realized on the mold bottom surface and the contact surface.

For example, when the particles of the stirred first stirring mixture are about 1 to 4 mm, the compressed thickness after injection of the mold in the injection and compression steps (S200, S1200, S3200) may be approximately 4 to 6 mm. Accordingly, the thickness of the final product can be manufactured to about 8 to 12 mm.

In addition, one example will be described with reference to FIGS. 2 to 5. At this time, in the injection and compression steps (S1200, S3200), spray the fresh water evenly on the bottom of the prepared mold with a spray and inject the first stirred mixture. Before pouring the stirred first stirring mixture into the mold, spray the pure water evenly with a spray or the like on the bottom of the prepared mold, and inject and compress the first stirring mixture to make the water and the first stirring mixture compatible (互換), followed by the drying process ( After passing through S600), the contact surface in contact with the bottom surface of the mold, that is, the surface of the final product is smooth and has a soft glow, and has a texture similar to that of natural stone marble.

In particular, referring to FIGS. 3 to 4, since the first stirring mixture is colored in a single color or multicolor, spraying clean water on the prepared mold bottom before injecting the stirred first stirring mixture into the mold and then injecting the first stirring mixture When compressed and dried, the contact surface that comes into contact with the mold floor is shiny, shiny, and tinted and can exhibit a texture similar to natural stone marble. In the injection and compression steps (S1200, S3200) described below, a first stirring mixture composed of agitated particles having a particle size of about 1 to 4 mm colored by stirring with colored first stirring water as shown in FIGS. After injecting it into the mold evenly and compressing it to dry it, the colored grains in the final result appear naturally on the surface layer. At this time, the mixed stone solid colored in monochromatic or multicolored due to compression has a natural color and does not discolor even after the construction of the final product.

In this manufacturing process, unlike the existing method, the surface has a subtle color (like marble) with a new mechanism, and it is strong, smooth, and embossed with irregularities. Products that can be equipped can be manufactured.

Although not shown, in one example, without performing the ombre process in the first stirring step (S100, S1100), for coloring the product in the injection and compression steps (S200, S1200), spraying the dye water to the bottom of the prepared mold Sprinkle with a back and the first stirred mixture can be injected. That is, before the first stirring mixture is injected in the injection and compression steps (S200, S1200) without the ombre process in the first stirring step (S2100, S3100) in FIGS. 3 to 4, water containing a pigment is sprayed with a spray or the like. Dyeing with a different feeling may also be implemented by a post-dyeing method of injecting the first stirring mixture.

The mixing ratio of the second stirring mixture and water is secondly stirred in a thick state at a ratio of 7:3 to 3:2 by volume. At this time, since the mixing ratio is high, the wet-stirred dough becomes thick as a whole.

In the second stirring step (S400), the first remaining stirring step (S100, S1100, S2100, and S3100) is stirred more dilutely to fill the predetermined remaining portion of the mold in the remaining molding step (S500), which will be described later, and the lower layer (bottom layer) of the final product When forming (refer to reference numeral 300 in FIG. 6), a flatter and smoother floor surface is formed, which makes it easy and convenient to attach to a wall of a building.

Residual molding step (S500)

Next, the residual molding step S500 will be described with reference to FIGS. 1 to 5. In the remaining molding step (S500), the second stirring mixture stirred in the second stirring step (S400) is injected into the upper part of the mold's strength reinforcing material to fill the predetermined remaining portion of the mold and semi-dry.

At this time, in the remaining molding step (S500), the remaining portion may be filled and the upper surface may be horizontally arranged. For example, the second stirring mixture is injected into the other half of the mold, and the surface is horizontally and smoothly completed using a tool such as a horn to make an attachment surface attached to the wall of the building.

For example, the semi-drying time may be performed while drying at room temperature for about 5 to 10 minutes, and may be adjusted according to embodiments.

Demolition and drying step (S600)

Next, referring to FIGS. 1 to 5, the demoulding and drying step (S600) is examined, and in the demolding and drying step (S600 ), the mold is demolded in a semi-dry state and dried in a drying furnace.

For example, it can be dried within a range of about 30 to 90 minutes at a temperature of about 80 to 100 degrees in a drying furnace, and the drying temperature and drying time can be appropriately adjusted according to an embodiment.

Surface treatment step (S700)

In addition, one example will be described with reference to FIG. 5. In this case, the method for manufacturing a building interior material may further include a surface treatment step (S700). In the surface treatment step (S700), a pattern is formed on the surface of the product demolded or dried in the demolding and drying step (S600) by a marbling method or a digital printing method, or an image is formed by a digital printing method.
