The present invention relates to a gypsum-containing heating floor board and a method for manufacturing the same, which will be described in more detail, which is based on gypsum having excellent sound insulation and flame retardancy, and releases charcoal powder having excellent deodorization and decontamination performance, and anion and far infrared rays. By manufacturing a floor plate with an illite-containing composition and disposing a planar heating element therein, there is little emission of volatile organic compounds (VOC) such as formaldehyde, and it is light and has excellent impact strength. The present invention relates to a gypsum-containing heating floorboard which is very suitable as a well-bing floorboard because a large amount of negative ions and far-infrared rays are released together with heat generation.

Artificial plywood, which is widely used as building floor boards, can be classified into so-called veneer plywood, aggregated wood, artificial wood, and the like. Among them, artificial wood is a medium-density fiber-board (MDF) that is compressed into a flat plate form by mixing glue with wood crushed wood fragments to have a medium density, and synthetic resin adhesives on fibrous particles such as wood. It is classified as a particle board which is spray-coated with a high-density thermoforming. Here, particle board is also called chip-board or flake board, which has the advantage of uniform strength, shrinkage or expansion force in the plane and hardly cracking, so it has been used for furniture and building interior materials for a long time. Has been used.

However, in spite of the convenience of processing such as perforation, painting, printing, adhesion, etc., since the particle board contains a large amount of synthetic resin adhesive, when used as a furniture or interior finishing material, volatile organic compounds (VOC) such as formaldehyde Concerns have been raised that this release could adversely affect the human body.

On the other hand, gypsum board widely used as interior materials for building is filled with gypsum hardened in a stable crystal state between two strong board base materials, and it has various characteristics that building interior materials should have, namely, fire resistance, elasticity, insulation and economic efficiency. Equipped evenly. However, these gypsum boards are fragile and fragile, heavy, and weak in moisture, and thus are mainly used as walls or ceiling finishes, but are rarely used as flooring materials.

In addition, domestic utility model registration No. 344172 (published date: 2004.03.09.) Has introduced a flooring material consisting of a planar heating element and a heat sink. Here, the planar heating element is a plurality of heat dissipation pieces are formed so as to be spaced apart at a predetermined distance in the center portion, a plurality of long holes are formed between the heat dissipation pieces, each side end of the heat dissipation piece is a plate-shaped with a power supply piece, respectively, A plurality of heat dissipation installation grooves are formed so that the heat dissipation pieces of the surface heating element are installed, and a plurality of heat insulation holes penetrating between the heat dissipation installation grooves are formed, and both sides are formed with a structure in which a power installation piece is installed. However, since the conventional heat generating flooring material does not use a synthetic resin adhesive, there is no fear of volatile organic compound (VOC) being released. However, since the inside of the heat sink is empty, sound insulation is poor and durability is weak. There is a need to develop a heating floor material of more diverse materials.

Accordingly, an object of the present invention is a floor plate material comprising gypsum having excellent sound insulation and flame retardancy as a main component, and a charcoal powder having excellent deodorization and decontamination performance and an illite which emits anions and far infrared rays. By disposing a planar heating element therein, there is no emission of volatile organic compounds (VOC) such as formaldehyde at all, light and excellent impact strength, especially when the power is applied, a large amount of negative ions and far infrared rays are released with heat Therefore, it is to provide a gypsum-containing heating floorboard and a manufacturing method thereof which are very suitable as a well-bing floorboard.

According to the present invention, a band-like planar heating element is disposed side by side in a plate body including 45 to 60 parts by weight of gypsum, 12 to 20 parts by weight of charcoal powder, and 25 to 35 parts by weight of illite powder. Both ends of the power supply line is connected, the edge of the plate is provided with one to four wire connectors connected to the end of the power supply line, the surface of the plate is characterized in that the coating of a synthetic resin film for gel coat (gel coat) It is the floorboard material for plaster-containing heating.

Method for producing a floor board according to the present invention is mixed with water in a ratio of 1: 1 in a composition consisting of 45 to 60 parts by weight of calcined gypsum, 12 to 20 parts by weight of charcoal powder, 25 to 35 parts by weight of illite powder. Shaping and drying a plate-shaped substrate with the composition; Forming a perforated substrate by applying a planar heating element side by side in a band shape to one surface of the substrate, and forming a long hole in a space between the band and the strip of the planar heating element; Connecting a power supply line to both ends of the perforated substrate, and installing a wire connector at an end thereof; Forming upper and lower layers by applying a composition having the same configuration as the substrate molding composition to both sides of the perforated substrate; Sanding the surface of the plate and applying a gel coat synthetic resin to the surface; Is made of.

Prefabricated floor board according to the present invention is a rectangular plate, for example, 45 to 60 parts by weight of gypsum, 12 to 20 parts by weight of charcoal powder, 25 to 35 parts by weight of illite powder.

First, gypsum, which functions as a binder in the present invention, is calcium sulfate dihydrate (CaSO ₄ · 2H ₂ O), which is flame retardant and has excellent soundproofing, heat insulating properties, and the like. It is widely used. When gypsum is heated at a temperature of about 120 ° C. for several hours, it becomes calcium sulfate hemihydrate (CaSO ₄ · ½H ₂ O), that is, calcined gypsum, and when gypsum absorbs moisture and hardens, it becomes gypsum. Calcined gypsum has fine crystals and requires a large amount of water to knead to an appropriate viscosity. Plastered gypsum is also used for gypsum plaster, architectural gypsum board, ceramic molds, metal molds, and medical applications. Gypsum comprises 45 to 60 parts by weight of the total components as the main component constituting the plate of the present invention. If the content of gypsum is 45 parts by weight or less, the durability of the plate is not good, whereas if it is 60 parts by weight or more, the content of the charcoal powder and the illite is reduced, so that the functionality is deteriorated.

Next, as well known charcoal powder, as a porous material has excellent deodorizing effect, humidity control effect, harmful electromagnetic wave blocking effect, negative ion generating effect and the like. Therefore, in the present invention, the charcoal functions to form fine pores inside the plate to remove harmful volatiles as much as possible, purify indoor air, and control humidity. Charcoal powder is most effective to use a particle size of 30 to 150 mesh in consideration of compatibility with other composition components, especially gypsum binder. In addition, if the content of the charcoal powder is 12 parts by weight or less, the effect of adding charcoal is insignificant, on the contrary, when the content of the charcoal is 20 parts by weight or more, the content of the gypsum is too small, resulting in a problem that physical properties such as strength of the plate material are lowered.

Also, illite powder is a mica-type clay mineral widely distributed in marine shales and related sediments, which contains more water and less potassium than real mica but has a mica-like layered structure. The illite powder adsorbs and decomposes various heavy metals in the atmosphere, and generates a large amount of anions, especially at room temperature of 18-25 ° C. In addition, it has been reported to have a function of emitting about 93% of far infrared rays at room temperature, and has a bacteriostatic effect of inhibiting viruses, bacteria, fungi, and the like. Therefore, the illite powder exhibits optimum efficacy when the planar heating element installed inside the substrate is properly heated. In the present invention, the content of the illite powder is most effective when 25 to 35 parts by weight.
