Manufacturing method of heated flooring {MANUFACTURING METHOD FOR HEATING FLOOR MEMBERS}

The present invention relates to a heated flooring material and a method for manufacturing it, and more particularly, to a heated flooring material having a heating function in tiles and CRC boards used for flooring in a building, a flooring for a bed or a sofa, and a method for manufacturing such a heated flooring it's about

In general, an interior material in the form of a plate molded from tile, wood, metal synthetic resin, etc. is attached to the interior wall of a building to decorate a set space.

Most of these building interior materials have a problem of heavy weight and are mostly used only as simple architectural interior materials that are not given any functionality but are configured to have a beautiful appearance.

On the other hand, indoor heating consists of ventilation heating, in which cold air is heated with warm air by means of an electric heater, and blown into the room, and radiant heating, in which the floor or wall is heated and the room is warmed by radiation from the floor or wall. divided into two types.

Since the heating efficiency of the radiant heating is relatively good, it is mainly used now. As a heating method of this radiant heating, a method of heating the floor or wall by guiding hot water through a pipe under the floor or behind the wall, heating wire There is a method of heating the floor or wall by burying it in the floor or wall.

Here, the hot water heating type is gradually being replaced by the heating wire heating type because there is a risk that water may leak as the pipe decays or is damaged.

However, even in the case of the heating wire heating type, before installing the floor or wall surface, first lay the heating wire on the floor or wall, then pour the cement, and after the cement is cured and dried, the upper surface of the cement is decorated with tiles for decoration or other surfaces. Because it has to go through a series of complicated constructions such as installing and fixing more, it requires a lot of labor and construction costs, and it has the disadvantages of generating a lot of electromagnetic waves harmful to the human body.

In order to compensate for these shortcomings, floor heating using a planar heating element or a linear heating element that generates less electromagnetic waves and can easily transfer heat is used.

In particular, in the construction of floor heating using a planar heating element, the floor surface to be heated is

It is used by laying a heat insulator on the floor, using a commercially available pouch film on it, stacking a planar heating element, and finishing it with a finishing material.

However, the planar heating element is weak in strength and can be easily damaged by an external shock, and is weak to moisture, which can cause a fire due to a short circuit, and when the planar heating element is partially damaged, there is a problem in that some repairs are difficult.

On the other hand, Korean Patent Application Laid-Open No. 10-2015-0099894 discloses a “heat block”.

In the 『Block for heating』, a heat conducting solution or heat conducting paste is applied on the upper surface of the square block base where the cover fitting groove and the heating wire fitting groove are formed, and the heating wire is inserted into the heating wire fitting groove, and a cover is placed in the cover fitting groove. covered structure.

However, the "heat block" has the following disadvantages.

First, since a heating wire and a heat-conducting solution (heat-conducting paste) are applied as a heating medium, it is difficult to secure a sufficient connection area between them, which causes problems such as poor connection and sparks, etc. Functionality degradation as well as safety There is a problem with the side.

Second, there is a disadvantage in terms of manufacturability and workability that the heating wire must be mounted after machining a heating wire fitting groove on the upper surface of the square block base in order to insert the heating wire into the square block base.

6 is a cross-sectional view illustrating a heated flooring material according to an embodiment of the present invention;

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

1 to 3 are perspective views illustrating a method for manufacturing a heated flooring material according to an embodiment of the present invention, and FIG. 4 is a block diagram illustrating a method for manufacturing a heated flooring material according to an embodiment of the present invention.

As shown in FIGS. 1 to 4 , the method for manufacturing a heated flooring material is used when finishing the interior floor or wall surface of a building, or used as a flooring material for a bed or sofa, and CRC (Cellulose Fiber Reinforced Cement) It is a method of manufacturing a tile and CRC board combination type heated flooring material that can exert a heating function as well as the original role of the flooring material by applying a heating means, for example, a heating paint, to the board.

To this end, as a first step, a step of forming the tile 10 by a known method is performed (S100).

Usually, tiles can be made of clay baked with fire, and it is preferable to form them using materials such as glass, asphalt, asbestos, cement, and the like.

Here, in the case of a floor tile, it can be molded into fine clay compressed by a machine, and the floor tile is completely transformed into a glassy material to exhibit very hard properties.

And, in the case of wall tiles, a glazed semi-vitreous or semi-crystalline ceramic tile made of fireclay or shale may be applied, and it is preferable to apply a normal polishing tile.

Next, as a second step, each of the band-shaped silver pastes 11a and 11b having a predetermined width is applied to both edges of the bottom surface of the tile 10 ( S110 ).

That is, the silver faces 11a and 11b are applied in two rows along both edges of the bottom surface of the tile 10, which is the side in contact with the top surface of the CRC board 15, and the silver pastes 11a and 11b at this time have the entire width ( Or length) can be applied in the form of extending in parallel in a straight line.

Here, the silver pastes 11a and 11b may be applied to a thickness of about 0.1 to 1 mm and a width of about 10 to 15 mm, for example, a width corresponding to the width of the copper plates 17a and 17b to be described later. there will be

The silver pastes 11a and 11b are conductive materials for improving the contact between the copper plates 17a and 17b to be described later serving as electrodes and the heating paint 13 .

Next, as a third step, a first heat treatment step of preheating to semi-permanently fix the silver pastes 11a and 11b to the side of the tile 10 as well as a close bond between the tile 10 and the heating paint 13. carry out (S120).

The first heat treatment step for the tile 10 is to maintain the entire tile 10 at an appropriate temperature after applying the silver pastes 11a and 11b and before applying the heating paint 13 to the heating paint 13 . This is a step of allowing the silver pastes 11a and 11b to be hardened so that they can be uniformly and closely applied to the surface of the tile 10 and to be completely in close contact with the tile side.

To this end, the tile 10 coated with the silver pastes 11a and 11b is placed in a chamber 12, for example, a kiln, and a primary heat treatment is performed at a temperature of 120 to 150° C. for 10 to 20 minutes.

Here, if the heating paint 13 is directly applied at room temperature without preheating the tile 10 , the adhesive force between the heating paint 13 and the tile 10 , that is, the adhesive force decreases, as well as the heating paint. The heating paint 13 is not uniformly applied to the surface of the tile 10 such that (13) is easily volatilized (increased).

In consideration of this point, in the present invention, as a step before applying the heating paint 13 , the first heat treatment step is performed on the tile 10 .

By preheating the entire tile uniformly during this preheating process, it can maintain a uniform dry state without flowing even after applying heat-generating paint. be able to form

In addition, since the silver pastes 11a and 11b applied to the tile 10 in the first heat treatment step are also dried by heat, the traction and conductivity are improved, and the silver paste is completely fixed to the tile side, thereby exhibiting its functions semi-permanently. be able to

Next, as a fourth step, after the first heat treatment, a step of applying the conductive heating paint 13 over the entire area of the bottom surface of the tile 10 is performed (S130).

The heating paint 13 is a paint that generates heat from the entire surface of the paint layer by an electric current supplied through the paint layer, and is called CNT ink or CNT paint.

As an example, in the heating paint 13 of the present invention, as an example, a conductive paint in which carbon black, graphite particles, etc. are dispersed in a conductive polymer and an inorganic binder can be applied.

The heating paint 13 can be applied to a thickness of about 2 to 5 μm by an automated process using a spray gun or the like, or by a manual operation in which an operator directly paints with a brush or the like.

Accordingly, when an electric current is applied to the heating paint 13 applied to the surface of the tile 10, heat is generated due to the characteristics of the conductive paint containing graphite, etc. It is possible to heat the room by using the heat generated from the floor or the wall itself.

By applying a heating method that generates heat by using the heating paint 13 in this way, energy efficiency is higher than that of a conventional nichrome wire, and it is possible to heat a room in a very eco-friendly manner without the influence of electromagnetic waves.

Next, in the fifth step, a second heat treatment step is performed to stabilize the heating paint 13 applied to the tile 10 and remove residual moisture (S140).

That is, the tile 10 coated with the heating paint 13 is placed in the chamber 12, for example, a kiln, and secondary heat treatment is performed at a temperature of about 120 to 150° C. for 10 to 20 minutes.

After the application of the heating paint 13 in this way, secondary heat treatment is performed on the tile 10 so that the heating paint 13 uniformly applied to the tile 10 can be stabilized while closely adhering to the tile surface. In addition, it is possible to secure the quality of the heating performance of the heating paint 13, such as remaining moisture contained in the heating paint 13 can be completely removed.

When the first to fifth steps are passed, the upper heated flooring 14 made of the tile 10 to which the second rows of silver pastes 11a and 11b and the heating paint 13 are applied can be manufactured. .

Meanwhile, after the fifth step, the step of applying a top coat (not shown) to protect the heating paint 13 formed on the surface of the tile 10 may be further performed.

The top coat finally cleans up and coats the finished surface, serves to protect it from external stimuli or exposure to sunlight, and can be applied for gloss.

A urethane-based or epoxy-based paint can be applied to such topcoat paint, and the topcoat paint can be applied to a thickness of 5 to 15 μm. It can be cured (dried) for ∼40 minutes.

Next, as a sixth step, a step of molding the lightweight high-density CRC board 15 by a known method is performed (S150).

The CRC board 15 is a non-combustible material produced by mixing cellulose fibers, which are natural pulps, Portland cement, silica sand, etc., with water and pressurizing it to a predetermined pressure, and then undergoing an autoclave curing process. As a material, it is a lightweight, high-density CRC board (Cellulose Fiber Reinforced Cement Board) that is mainly used for foundation work such as bathrooms, kitchens, basement barriers, partitions, inner walls between households, escape routes between households, and non-extended balcony walls.

Next, as a seventh step, a heat treatment step for removing moisture, etc. remaining on the CRC board 15 is performed (S170).

That is, the CRC board 15 is placed in the chamber 12 and heated at a temperature of about 50 to 70° C., preferably at a temperature of 60° C. for a time of about 60 to 180 minutes, remaining in the CRC board 15 . Steps to remove moisture, etc. are carried out.

Next, as an eighth step, a step of applying the waterproofing solution 16 over the entire area of the top and bottom surfaces of the CRC board 15 after heat treatment is performed (S170).

Here, the waterproofing solution may be a known cement waterproofing solution.

As a preferred embodiment, after applying the waterproofing solution 16 on both sides of the CRC board 15, a heat treatment step (for example, putting the CRC board in a chamber and heat-treating it at a temperature of 120 to 150° C. for 10 to 20 minutes) It can be further carried out, and as a result, the waterproofing liquid 16 applied to the CRC board 15 is dried and all remaining moisture can be removed.

Next, as a ninth step, a step of attaching the copper plates 17a and 17b serving as electrodes to the upper surface of the CRC board 15 is performed (S180).

That is, strip-shaped copper plates 17a and 15b having a predetermined width and thickness are attached along both edges of the upper surface of the CRC board 15 .

In this case, a known heat-resistant silicone or the like can be used as an adhesive for attaching the copper plates 17a and 17b.

And, in the ninth step, when the copper plates 17a and 17b are attached to both edges of the upper surface of the CRC board 15, the copper plates 17a and 17b on both sides are applied to the tile 10 in two rows of silver paste ( 11a, 11b) can be attached at an interval corresponding to the distance between and the lower copper plates 17a and 17b can be arranged in parallel with each other.

Here, as the copper plates 17a and 17b, a copper plate having a thickness of about 0.1 to 0.5 mm and a width of about 10 to 15 mm may be applied.

In particular, in the case of the copper plates 17a and 17b, since they are of a relatively wide plate type compared to the existing wire-type heating wires, it is possible to sufficiently secure a connection area with the heating paint 13 side. , in addition to this, since the copper plates 17a and 17b are electrically connected to the heating paint 13 side together with the silver pastes 11a and 11b, stable and close conductive performance can be secured, and problems such as poor connection are completely eliminated. can be excluded.

When these 6th to 9th steps are passed, the lower heated flooring 18 made of the CRC board 15 to which the two rows of copper plates 17a and 17b are attached and the waterproofing liquid is applied at the same time can be manufactured. .

Next, as a tenth step, the step of stacking and bonding the upper heated flooring material 14 and the lower heated flooring material 18 up and down to complete the heated flooring material is performed (S190).

For example, silver pastes 11a and 11b and heating paint 13 on the bottom surface of the lower heated flooring material 18 made of the CRC board 15 to which two rows of copper plates 17a and 17b are attached to the top surface. The top heated flooring 14 is laminated with the applied tile 10 and vertically combined.

At this time, it is possible to use a known heat-resistant silicone or the like as an adhesive for bonding between the upper and lower heated flooring materials 14 and 18 .

In this way, the upper heated flooring 14 and the lower heated flooring 18 are stacked and combined to form one finished heated flooring, so that the copper plates 17a and 17b attached to the lower heated flooring 18 and the upper heated flooring As the heat dissipation paint 13 applied to (14) comes into contact, they are electrically connected, and accordingly, when a current from an external power source is applied to the copper plates 17a and 17b serving as electrodes, the current at this time is the copper plate ( 17a and 17b) and the heating paint 13 and the silver pastes 11a and 11b, which eventually leads to the heating of the heating paint 13, and can serve as a heating flooring material.

In particular, the copper plates 17a and 17b are in direct contact with the side of the heating paint 13 while in close contact with the side of the silver pastes 11a and 11b through the heating paint 13 as a medium. , 17b), the heating paint 13 and the silver pastes 11a and 11b can be electrically connected to each other over a sufficient area.

In this way, the copper plates 17a and 17b and the heating paint 13 are directly electrically connected to each other, and at the same time, the copper plates 17a and 17b are connected to the heating paint 13 through the silver pastes 11a and 11b. Since they are connected, it is possible to secure a large and sufficient connection area between them, and consequently, poor connection, spark generation, resistance increase, etc. It is possible to stably conduct electricity without any problems.

When the step of combining the upper heated flooring 14 and the lower heated flooring 18 is completed in this way, a product as a building interior material having a heating function, a flooring product such as a bed or a sofa, can be completed.

For example, the product completed through the first to tenth steps as described above, that is, the tile 10 and the CRC board including the heating paint 13, the copper plates 17a and 17b, the silver paste 11a, 11b, etc. (15) Combination type heated flooring can be installed on the indoor floor or wall surface of a building, or used as a flooring material when manufacturing a bed or sofa.

Therefore, when power is connected to an input line (not shown) drawn out from the copper plates 17a and 17b of the heated flooring material and a current is applied, heat is generated in the heating paint 13 of the heated flooring material and, as The generated heat is transferred to the side of the tile 10 in contact with it, and the tile 10 is also heated, and eventually the room can be heated through the heated flooring material forming the interior material of the indoor floor or wall surface, or forming the floor of a bed or sofa The heated flooring material makes it possible to provide warmth to bed and sofa users, while minimizing the generation of electromagnetic waves due to the heat generated by the heat-generating paint. You can keep it running, so you can save on heating costs.

In the upper heated flooring 14, band-shaped silver pastes 11a and 11b having a predetermined width are applied to both edges of the bottom in parallel, and the total area of the bottom to which the silver pastes 11a and 11b are applied. It includes a tile 10 to which a heating paint 13 is applied over the tile.

At this time, the heating paint 13 can be applied to a thickness of about 2 to 5 μm.

The lower heated flooring 18 has a strip-shaped copper plate 17a having a predetermined width on both edges of the upper surface where the waterproofing liquid 16 is applied over the entire area of the upper and lower surfaces, and the waterproofing 16 is applied, 17b) includes a CRC board 15 attached side by side.

In addition, the upper heated flooring 14 and the lower heated flooring 18 are combined in a vertically stacked structure.

That is, an adhesive such as heat-resistant silicone is applied between the bottom surface of the tile 10 of the upper heated flooring 14 and the upper surface of the CRC board 15 of the lower heated flooring 18 to form the upper and lower heated floorings 14 and 18. By being integrally combined, a heated flooring material that can be used as an interior material or a flooring material can be completed.

In this way, on the inside of the heated flooring made of the combination of the upper heated flooring 14 and the lower heated flooring 18, that is, the surface where the tile 10 and the CRC board 15 are in contact, with the heating paint 13 interposed between the two rows of silver The pastes 11a and 11b and the copper plates 17a and 17b are arranged side by side.

In particular, the spacing between the silver pastes 11a and 11b of the tile 10 and the spacing between the copper plates 17a and 17b of the CRC board 15 are the same as each other, and thus the upper heated flooring 14 and When bonding the lower heated flooring 18 , the upper silver pastes 11a and 11b and the lower copper plates 17a and 17b may be arranged in parallel with each other.

Accordingly, two copper plates 17a and 17b provided in the heated flooring material, that is, one copper plate 17a having a “+” pole and another copper plate 17b having a “-” pole, are connected to a power line (not shown). ) and power is applied, heat is generated from the heating paint 13, and the heat at this time is continuously transferred to the tile 10 side and the tile 10 is heated, and eventually the indoor floor surface or It is possible to heat a room through the heated flooring material forming the interior material of the wall, or it is possible to provide warmth to the bed or sofa user through the heated flooring material forming the floor of the bed or sofa.
