In the following the present invention will be described in detail with reference to the embodiments presented in the accompanying drawings. The examples presented are exemplary and are not intended to limit the scope of the invention.

1 shows a vertical cross section of a building interior material 1 according to the invention.

Referring to FIG. 1, the building interior material 1 includes an outer layer 11, an adhesive layer 12, and a backing layer 13.

The outer layer 11 may be a carpet or brushed fabric. Carpets are mainly made of nylon, but can be made of polypropylene, polyethylene terephthalate, polytrimethyl terephthalate, or any one of acrylic or mixed. The outer layer 11 according to the invention can be a carpet in tuft or pile form made from nylon, polypropylene, polyethylene terephthalate, polytrimethyl terephthalate or acrylic, but is not particularly limited in carpet form. In consideration of the object of the present invention, it is advantageous that the outer layer 11 has a structure capable of absorbing sound absorption and impact. Therefore, the outer layer 11 may have a structure in the form of a file. Alternatively, the outer layer 11 may be in the form of a moquette or velvet fabric having a pile-like structure, or a suede-like brushed fabric napping warp or circular knit fabrics.

The pile fabric is made by forming a ramp loop or by forming a loop with a weft yarn and then cutting the pile after weaving. Velvet is a light pile fabric representing a ramp pile and a soft pile or loop on the fabric base. Such a file or loop may be represented as a cut file or looped. The length of the pile thus formed may be 0.3 to 1 mm. Velvet can be divided into various types such as chiffon velvet, rayon velvet and brocade velvet, but the outer layer 11 of the present invention is not limited to this kind of velvet. The velvet is woven through a conventional velvet loom, but at the same time supplying the warp and weft for the base and weaving into a plain weave or twill to form a loop or cut it to form a pile. A typical manufacturing method is a wire method or a double fabric method in which two pile fabrics are obtained by cutting a knife between two layers of fabrics that are woven in a double woven tissue.

A moquette refers to a pile fabric with a fluff, and refers to a fabric capable of representing various patterns and capable of expressing various colors. Moquette fabrics are durable and can be used as chair skins for furniture, automobiles, rail cars or buses. The manufacturing method of the mocket is similar to velvet, and two sets of ground warp and ground weft are made into two ground weaves, and pile yarns are used. yarns are reciprocated between them to interweave the two fabrics as a weft warp or weft weft. Then, by cutting the file between the two pieces of paper with a knife, two pieces of moquette fabric with two file faces are in contact with each other.

There are various types of knitted brushed paper, such as circular knitted and warp knitted brushed paper. Circular knitting brush is knitted using biaxial polyester yarn so that it has a cylinder diameter of 30 inches and a needle knitting machine with 28 needles per inch (N.P.I) is 250-300 g / yard. As a conventional post-processing, circular knitting suede-like fabrics are produced through a process of refining, dyeing, heat setting, brushing, buffing and heat setting. In addition, warp knits are knitted in a tricot knitting machine having a gauge number of 28 to a course density of 18 to 30 and a width of 105 inches in a dough having a weight of 250 to 300 g / yard. The dough is brushed six times in hydraulic brushed paper, and then two times in a belted paper, which is a loop type cloth for hydraulic type, and a cut type for belt type. Absorption of was used. After brushing, the surface wool is cut uniformly to a length of 1 to 3 mm in a shaver.

Brushed fabrics have a coefficient of repulsion that is sufficiently small compared to their thickness, which results in high sound absorption and shock absorption effects. However, brushed fabrics have the disadvantage that dust is easily accumulated or microorganisms are easily generated. In order to eliminate this disadvantage, the outer layer 11 according to the present invention may be surface coated or antibacterial. Surface coating and antibacterial treatment may be achieved by coating the fiber yarn itself in the manufacturing process.

In general, the carpet may have a backing fiber, a bottom layer or bubbles and an adhesive layer may be formed between the backing fiber layer, the bottom layer or bubbles. The backing layer of the building interior material 1 according to the present invention is a honeycomb porous plate made of synthetic resin in place of the backing layer of the carpet. In general, the honeycomb structure is molded by extrusion in the form of a sheet using a material such as cordierite, alumina, silicon carbide, polyolefin resin or thermoplastic resin. The honeycomb structure consists of a number of hexagonal cells with a certain height, so that about 90% of the total is a hollow design. According to the invention, the honeycomb plate used for the backing layer 13 of the outer layer 11 can be made of synthetic resin such as polyolefin, polyester or polypropylene (PP) or aluminum and has a height of 10 to 30 mm. It has a cell structure. On both sides of the honeycomb, a thin sheet of metal or synthetic resin may be attached. Alternatively, the outer layer 11 may be attached to one side of the cell of the honeycomb, and the sheet of metal or synthetic resin may be attached to the other side. An adhesive layer 12 is formed for bonding the outer layer 11 and the cells of the honeycomb or for bonding the sheet and the honeycomb cell. The adhesive layer may be a melt adhesive film of a polyolefin system. Alternatively, acrylic resins, polyurethane resins or polyester resins may form the adhesive layer 12. In another alternative the honeycomb is bonded to the carpet layer, which is directly outer layer 11 by means of heat fusion or adhesive film, and the other side of the honeycomb cell is adhered by means of an adhesive film, for example to a gypsum board or a gypsum board It can be combined in such a way that it fits in the protrusions formed in the.

As described above, the honeycomb sheet according to the present invention may include a sheet of metal or aluminum material attached to both surfaces or one surface of the honeycomb cell, and the sheet is attached to the honeycomb cell using a heat-sealing or adhesive film. Can be. Honeycomb cells can also be bonded directly to one side of the carpet layer and the other side to the other material layer, for example gypsum board, by means of heat-sealing, adhesive film bonding or cell fitting into the protrusions. Can be. In addition, the combination of such honeycomb cells with other materials or layers may be made according to methods known in the art.

Although the honeycomb structure is described as an example of the backing layer 13 above, the present invention is not limited to this form. For example, the carpet layer that the outer layer 11 forms has a backing face that is generally made of fibers or nonwovens. Therefore, the honeycomb structure can be attached by forming the backing face sufficiently thin and forming the adhesive layer 12 on the backing face. The honeycomb sheet according to the present invention advantageously has porosity, firmness and elasticity. Such properties improve sound absorption, vibration absorption, heat insulation and fire resistance. The building interior material according to the present invention has an outer layer 11 made of a carpet of pile fabric and an inner layer having a honeycomb structure. Because of this, it has sufficient sound absorption and vibration absorption effect and can maintain the robustness.

Figure 2 illustrates a honeycomb structure that can be used on the backing face of the building interior according to the present invention. 2, the shape of the cell is in the form of a hexagonal column, but the structure of the cell may have a rectangular, pentagonal or any other shape. The building interior material according to the present invention including a honeycomb porous plate made of synthetic resin may be formed in various standards such as 50 * 50, 40 * 40 or 1200 * 2400 cm 2.

The building interior material according to the present invention is used as a wall, ceiling or floor of a building or an elevator to exhibit excellent sound absorption, vibration absorption and warmth. And since the inner layer is a honeycomb structure, the interior material itself has the advantage of being lightweight and robust. In addition, the carpet layer and the honeycomb structure has the advantage that can be manufactured in a variety of specifications. In particular, it has the advantage that it can be usefully used as a finishing material for indoor spaces that require sound absorption, shock absorption and thermal insulation while considering aesthetics.
