Description

[Technical Field]

[0001] The present invention relates to a ceramic tabletop material that can be given an inorganic feel and can change the atmosphere by giving it a tasteful and natural feel. [Background technology]

[0002] Traditionally, inorganic materials such as natural stone like marble and granite have been used to create unique tabletops for decorative tables with a natural feel. Their stately and luxurious feel has led to widespread expectations for tabletops for tables, counters, and other surfaces. Thinly sliced ​​natural stone allows light to pass through and retains moisture and air. Furthermore, marble and granite have unique characteristics that allow beautiful patterns to emerge, making them highly aesthetically pleasing and widely used as natural materials.

[0003] In forming a decorative layer by forming a coating film on the transparent plate surface of the object to be painted, decorative flat plates have been proposed in which an inorganic-style pattern is formed on the transparent plate surface or on the transparent plate surface formed by a special painting method.These decorative flat plates have been proposed as follows: a paint adhesion agent is applied to the transparent plate surface of the object to be painted, and then paint of a specific color that can be produced on the painted surface is applied 2-3 times to create an imprinted shape on the flat surface, forming a specially shaped pattern; and decorative flat plates have been proposed in which an inorganic-style pattern is formed on the transparent plate surface, which has been applied 2-3 times using a technique to release paint in granular form, resulting in a textured decorative flat plate material with a vintage look (see Patent Document 1).

[0004] In order to provide a safe glass composite material with an inorganic pattern for furniture that has both decorativeness and functionality and can be used for the tops of counters, tables, and other surfaces, or the decorative front panels of furniture, a safe glass composite material with an inorganic pattern for furniture has been proposed (see Patent Document 2). The safe glass composite material with an inorganic pattern for furniture is made by laminating a base wooden board to the back of the decorative inorganic pattern film body, which is a decorative inorganic pattern composite, and is composed of a composite decorative sheet made by laminating a polyvinyl chloride resin film to a polyester resin film on which an inorganic decorative pattern has been drawn or printed, and flat tempered glass to which the composite decorative sheet has been laminated with a special adhesive that forms a uniform adhesive layer.

[0005] A table with a special geometric pattern can be finished in a short time and at a low cost, is heavy but lightweight, and has a surface with a geometric pattern. The table is made by arranging rectangular, square, triangular, trapezoidal, and diamond-shaped resin tile surface finishing materials adjacent to each other on each side to form a geometric pattern, such as a star-, flower-, diamond-, polygon-, lattice-, or herringbone-like pattern array. The pattern arrays are arranged in multiple sets in succession in adjacent pattern arrays, and form unit repeating shaped elements formed on a base material. The unit repeating shaped elements are made into a geometric pattern decorative covering material with a special pattern that has an outer frame that fits the outer periphery of other unit repeating shaped elements. A table base with a geometric pattern top has been proposed in which the geometric pattern decorative covering material is fitted into the basic base of the surface material for a table or counter with a wide top (see Patent Document 3).

[0006] The proposed furniture is a wide-topped base that is heavy yet lightweight, has a mirror-like surface that is hard enough to prevent scratches, and has a scratch-resistant mirror-like surface, such as a table or counter with a wide top.The proposed furniture is made of a mirror-like thermosetting resin coated decorative surface material, a square-shaped flatness maintainer made of aluminum plate material and solid wood plate material for the surface material, and a basic base for the table or counter (see Patent Document 4).

[0007] To provide a table top made of a decorative inorganic material with a weighty feel and a surface pattern of natural stone or artificial stone, which has a natural feel, is heat-resistant, strong, and scratch-resistant, and has little moisture and gas respiration, but does not currently exist.

[0009] The present invention relates to the general use of inorganic material patterns on furniture surfaces. While inorganic decorative stone or printed glass surfaces with a rock pattern have been used on tables and countertops to improve heat resistance, strength, and scratch resistance, they have not been widely used on furniture that utilizes inorganic decorations. While the use of inorganic decorative materials is anticipated for their decorativeness and functionality, prior art has not yet addressed the issues of workability and weight. While decorative composite glass with a printed silicate-based inorganic material pattern applied has been used as a tabletop or countertop, it lacks the weightiness of natural stone. Glass decorative tops lack a natural appearance due to their smooth surface, and they are prone to repelling liquids, creating an uncomfortable feeling on the table. They are also susceptible to damage from heat resistance and impacts of heavy objects, and the natural decorative qualities of inorganic materials are somewhat lacking. Furthermore, natural stones such as marble and granite require a certain thickness to maintain their shape and strength. It is difficult to obtain wide-width silica-alumina monoliths, a natural stone component. Lightweight and strong materials are particularly important requirements for silica and alumina, which are formed from powder at high temperatures. To achieve the required thickness for furniture tabletops, a third additive must be added to the silica-alumina system. To address these issues, we propose a silica-alumina ceramic tabletop, similar to natural stone or artificial stone, that exhibits a decorative and heavy-looking inorganic pattern for furniture and is used for natural tabletops such as tables, counters, and other surfaces. The proposed tabletop features a specially designed decorative surface, and can be used for tables with composite legs, including custom-shaped legs, to match the tabletop. This can also be used for counter-mounted cupboards and TV stands. [Means for solving the problem]

[0010] Specific gravity 2~3, specific surface area 2.1~2.2m 2The tabletop material is a silica-alumina alkaline earth inorganic material with the characteristics of / g, and is made up of the upper surface layer of a flat ceramic board with a thickness of 3 to 5 mm and the lower back layer of a wooden board attached to the lower part of the ceramic board. The surface has a dark color and has a cluster-like uneven surface with a surface roughness of 0.01 to 0.1 mm deep, giving it a random cluster pattern in appearance. inorganic surface The ceramic top board material has a surface with a surface having a thickness of 1000 mm and can be used for table tops, cupboard counters, TV board tops, and desk tops, which are lightweight while maintaining mechanical strength.

[0011] Silica-alumina based alkaline earth inorganic materials with a specific gravity of 2 to 3 have a specific surface area of ​​2 to 2.5 m 2 / g, average pore size 8~10nm, volume pore size 0.004~0.005 cm 3 / g, and is made up of 55-60% silica, 17-20% alumina, 4-7% barium oxide, 3-5% magnesium oxide, 3-4% strontium oxide, and 2-4% calcium oxide. of Main component Compression molded as It is a heavy-duty molded board with a vertical width of 300 to 1000 mm and a horizontal width of 500 to 2000 mm, which is heat-resistant, impact-resistant, and hydrophobic. It has a porosity of 1.1 to 1.5% and a water absorption rate of 0.10 to 0.15%, and exhibits the properties of impact resistance and thermal stability.

[0012] Presenting an inorganic surface The tabletop material, which has a solid feel, has a flat surface with a width of 300 to 900 mm and a length of 500 to 1800 mm, and is joined and supported by a reinforcing wood material with a thickness of 15 to 30 mm. The surface is a silica-alumina alkaline earth inorganic ceramic board with a natural stone pattern, heat resistance at 400°C, and high impact resistance at a compressive strength of 10 KN. The surface has low water absorption and low adsorption properties, and is a flat surface with an uneven surface with scattered microscopic depressions and fine roughness, and is 3 to 5 mm thick. inorganic It consists of an upper layer which is the surface and a lower layer of hard wood material 20 to 40 mm thick.

[0013] The legs that support the tabletop, which is made of silica-alumina-based alkaline earth-containing inorganic material with a specific gravity of 2 to 3 and is used for the table, are L-shaped legs made of four disc-shaped plates, 700 to 750 mm long and 5 to 10 mm thick if made of steel, or wooden legs, 650 to 700 mm long and 30 to 50 mm thick if made of wood, and the tabletop supported by the legs is dark in color overall and has a slightly uneven, smooth surface with a rock pattern, so that when used as a cupboard counter or TV board top, it exhibits decorativeness and functionality with a heat-resistant, impact-resistant flat surface that gives it a natural feel. [Effects of the Invention]

[0014] While wood grain is commonplace on furniture surfaces and tabletops, inorganic patterns are rare. Natural or artificial stone, which offers heat resistance, strength, and scratch resistance, as well as shape permanence and moderate moisture absorption and breathability, offers the decorative qualities of inorganic rock patterns on tabletops and countertops. Tabletops with intricate stone patterns, created by the harmonious combination of the geometric dispersion of delicate particle shapes and the aggregate of natural rock particles, create a rock surface pattern that adds depth to the overall ambiance of the space in which it is used, are groundbreaking. When used as a tabletop, the heavy natural or artificial stone tops are supported by steel legs, which maintain strength and reduce weight, creating a solid yet stable table. In particular, ceramic offers practical heat and impact resistance, as well as water-repellent properties.

[0015] It is also heat-resistant and moisture-absorbent when used on a counter table in a cupboard. inorganic surface The weight of the natural stone increases when it comes into contact with the surface of the counter table, penetrates into the decorative tabletop, provides heat resistance when exposed to high temperatures, is not damaged by the impact of heavy objects, and has a natural, inorganic decorative quality. By changing the pattern of the composite legs, we were able to significantly change the pattern and atmosphere of the cupboard, which brings out the naturalness and decorativeness of the counter table surface to match the atmosphere of the room.

[0017] The present invention, which was invented to solve the above problems, explains the structure and type of table used as a tabletop material with a natural and heavy feel, as well as the state of the steel doglegs of the table, and clarifies its features. [Example]

[0018] As shown in Figure 2, the tabletop material is composed of an upper surface layer of a flat ceramic board made of a silica-alumina-based alkaline earth-containing inorganic substance, having a specific gravity of 2 to 3 and a thickness of 3 to 5 mm, and a lower back layer of a wood board attached to the lower part of the ceramic board.As shown in Figure 4, the surface has a surface roughness of 0.01 to 0.1 mm deep, and presents an inorganic surface pattern that appears to be a random group pattern.The ceramic tabletop material can be used as a tabletop or a cupboard counter.

[0019] As shown in Figures 1 and 2, the tabletop material exudes a natural feel. It has a flat surface measuring 300 to 900 mm in length and 500 to 1,800 mm in width, and is held together by a 15 to 30 mm thick reinforcing wood material. The surface has a dark natural stone pattern and is a silica-alumina alkaline earth-containing inorganic ceramic board that is heat resistant up to 400°C and has high impact resistance at a compressive strength of 10 KN. The upper layer has a smooth, finely textured, cluster-like surface, and the lower layer is a hard wood board 10 to 20 mm thick that supports the inorganic material of the upper layer.

[0020] As shown in Figure 3, the legs supporting the tabletop used for the table are made of four L-shaped steel legs and four disc-shaped plates, each 720 mm long and 10 mm thick.The tabletop material supported by the legs is made up of a slightly uneven, smooth surface overall, and has a heat-resistant, impact-resistant rock pattern that gives it a natural feel.

[0021] Heat resistance, impact resistance, and water resistance. Silica-alumina-based alkaline earth inorganic material has a specific gravity (density) of 2.45 at a thickness of 5 mm, as shown in Table 1. g / cm 3 As an inorganic material, it is in the relatively light category, and its density and pore volume are 0.0048 cm 3 / g, specific surface area 2.182m 2 / g, which is very small, indicating that it is a dense ceramic inorganic material. The characteristics that indicate this are a porosity of 1.18% and a water absorption rate of 0.14%, which indicate that it absorbs very little external gas or liquid. Therefore, it is expected that the water repellency on the surface will be improved and the growth of mold and bacteria will be reduced. As a dining table, it will not absorb water droplets, and the table surface will be kept hygienic. [Table 1] In order to demonstrate the above characteristics, the composition of the top plate must be affected by its properties, and the specific gravity must be 2.45 g / cm 3 The composition of the 3-5mm thick flat ceramic board is mainly composed of silica and alumina, as shown in Table 2. It is a molded board with a width of 300-900mm and a length of 500-1800mm, which is sintered and compressed and made from the main components of silica 59.07%, alumina 19.02%, barium oxide 4.78%, magnesium oxide 3.91%, strontium oxide 3.30%, and calcium oxide. It has the properties of impact resistance and thermal stability despite its density as a ceramic. [Table 2]

[0022] This silica-alumina ceramic exhibits excellent impact resistance, thermal stability, and hydrophobic properties. Figures 4 and 6 show the surface condition of the ceramic. The surface in Figure 4 resembles the surface of natural stone, smooth with a hint of roughness that conveys a natural appearance. The microscopic surface in Figure 6, a close-up photograph, shows a relatively rough surface with large holes and pits due to the contact and bonding of irregularly shaped particles in the crystal system. However, there are no large voids, and the ceramic appears to be a dense sintered body. Furthermore, as shown in Figure 8, FT-IR analysis of the surface composition yielded the results shown in Table 3. [Table 3] Furthermore, as shown in Figure 7, the X-ray photoelectron spectroscopy (ESCA) analysis results indicate that the predominant component is silicon oxide. The surface photograph (Figure 7) shows the aluminum (Al) component on the surface before the ESCA analysis. The aluminum is dispersed irregularly across the surface, resulting in a non-uniform composition. The silicon (Si) component on the surface is slightly uneven, but uniformly dispersed overall. The oxygen (O) component on the surface is present as an oxide on the front. A large amount of silica appears to cover the surface. The iron (Fe) component is dispersed uniformly, although it contains a small amount of Fe. This is due to the metallic components of Fe and Co, which color the rock-like ceramic, resembling the natural rock. The carbon (C) component on the surface is distributed in a slightly thicker and thinner distribution on both the upper and lower outermost layers, indicating that only the outermost surface is treated with organic components.

[0023] The silica-alumina-based alkaline earth inorganic material, which has a solid heat resistance, impact resistance, and water resistance, was subjected to a compression test using a 5mm flat plate. The results are shown in Figure 9 and Table 4. 1348 It was broken by N, but showed considerable stability against flat glass plates. It showed high compressive strength with a thin silica-alumina plate with a specific gravity of about 2.5, indicating that it is very stable against collisions and drops of heavy objects. [Table 4] 1 Newton (N) is the force of 1 meter per second (m / s) moving through an object with a mass of 1 kilogram. 2 ) is defined as the force that causes an acceleration of 1N. The second law of motion is F=ma, where F is force, m is mass, and a is acceleration. 1N=1kg·m / s 2 [Example]

[0024] The tabletop material used is a ceramic tabletop material that can be used for a cupboard counter, and is composed of an upper surface layer of a flat ceramic board made of a silica-alumina-based alkaline earth-containing inorganic material and a lower back surface layer of a wooden board attached to the lower part of the ceramic board.The tabletop material has a surface with a cluster-like uneven surface with a surface roughness of 0.01 to 0.1 mm deep, and exhibits an inorganic surface pattern that appears to be a random cluster pattern, as shown in Figure 1B.

[0025] The counter top of the cupboard is a flat surface with a width of 1300 mm and a depth of 450 mm, which is joined and supported by a 20 mm thick reinforcing wood material, and is an impact-resistant silica-alumina alkaline earth inorganic ceramic board with a natural stone pattern on the surface, and has a fine uneven surface. inorganic The upper surface and 20mm thick hard wood board of The cupboard is 1370mm wide, 490mm deep, and 1980mm high, and has three levels, with the upper level consisting of a shelf with sliding doors, a middle counter, and a lower level with hinged doors, drawers, and a blank space.

[0026] The heat-resistant, impact-resistant, and water-resistant silica-alumina-based alkaline earth-containing inorganic material used was the same as in Example 1, and as shown in Table 1, it had a specific gravity (density) of 2.45 g / cm at a thickness of 5 mm. 3 As an inorganic material, it is in the relatively light category, and its density and pore volume are 0.0048 cm 3 / g, specific surface area 2.182m 2 / g, which is very small, indicating that it is a dense ceramic inorganic material. The properties that indicate this are a porosity of 1.18% and a water absorption rate of 0.14%, which indicate that it absorbs very little external gas or liquid. Other properties were the same as in Example 1. [Explanation of symbols]
