In addition, terms defined in the present specification and claims are not to be interpreted as limiting, and may be changed according to the intention or custom of the operator, and should be construed in a meaning and a concept consistent with the technical idea of the present invention.

In one aspect of the present invention,

FIG. 1 is a perspective view showing a heating structure for preventing height difference of floor finishing materials according to a preferred embodiment of the present invention. FIG. 2 is a perspective view of a heating structure for preventing height difference of floor finishing materials according to a preferred embodiment of the present invention. Sectional view showing the heating structure in detail with reference to Figs. 1 and 2.

In a heating structure including a heating material installed on the floor,

The heating structure

A heat insulating material attached to the upper surface of the indoor floor;

A heating member installed on the upper surface of the heat insulating material to generate heat;

An MDF protection material installed on the top surface of the heating material to prevent a change in the height of the heating structure, which may be generated by damage to the heating material and pressure transmitted to the top surface; And

And a finishing material composed of one of a reinforcing floor or a decorative floor tile installed on the upper surface of the MDF protecting material.

The heating material is one selected from a heating film, a PVC hot wire coated with PVC on a hot wire, a hot water heating material using hot water, and an electric panel on which a stone or a metal forms an outer surface.

The heating film may be a planar heating film using carbon, but a planar heating film using carbon fiber may be used.

FIG. 3 is a detailed plan view of a heating member of a heating structure for preventing height difference of floor finishes according to a preferred embodiment of the present invention when the heating member is used as a PVC hot wire.

The PVC hot wire has a structure in which a PVC hot wire is adhered to an upper surface of an EVA having a thickness of 2 to 3 cm and a kraft paper is covered thereon. The PVC hot wire interval is 3 to 5 cm, 3 cm to 4 cm apart.

Therefore, the radius of alternatingly arranged PVC hot-wire inflection points is arranged to be 1.5 to 2.5 cm.

On the other hand, since the silicon heat ray is used as a heating element, when the electric power of the PVC heat ray is compared with that of the silicon heat ray of the present invention, if the silicon heat ray has a heating value of 15W per unit, It is a fact that the heating value of PVC hot wire is lowered.

In order to compensate the calorific value of the PVC hot wire, the arrangement of the PVC hot wire and the silicon hot wire under the same conditions (based on the size of the electric panel of 850 X 1700 mm) has the following effect or difference.

PVC heat lines are arranged at intervals of 3 cm and arranged by 4 cm from the side edge of the panel, a heat line of about 42 meters is used, and a silicon heat line of about 28 m is used for the same heat generation.

The above conditions are set for achieving the same heat generation, and the feeling of heat sensed by the panel is considerably different.

Because the PVC hot-wire is arranged in a relatively tight arrangement, the hot heat sensation is obtained without a difference in the warmth of the panel as a whole. Unlike the silicon hot-wire, the heat is hot in the arrangement of the hot-wire and relatively cold in the mid- In the overall cold feeling of the panel, the electric heating panel by the PVC hot wire is much better.

This is also due to the fact that the heat generated by the silicon hot wire gives a higher heating value per unit length, which makes some places too hot and somewhere too cold to feel a warm sensation.

That is, although the PVC hot wire has a lower calorific value, the PVC hot wire array of the present invention is more densely arranged and has a uniform heat sensation effect.

FIG. 4 is a detailed view of a heating material for preventing height difference of floor finishes according to a preferred embodiment of the present invention when the heating material is used as a hot water heating material.

The hot water heating material is composed of a compressed styrofoam and a hot water pipe formed with a space for inserting a small hot water pipe downward from the upper surface, and the hot water pipe has an interval of 15 to 25 cm to deliver a uniform heat sensation from the hot water.

The MDF protective material is a MDF impregnated with a flame retardant. The flame retardant includes 35 to 45% by weight of ammonium polyphosphate, 12 to 25% by weight of aluminum hydroxide, and 25 to 35% by weight of graphite, , And the flame retardant is impregnated with a water-soluble flame retardant diluted with distilled water or the like in a 30% by weight ratio in an MDF protective material for 5 minutes.

The impregnation treatment of the flame retardant can be replaced by a method of coating and drying. In the case of a heating material using a flame retardant, in particular, a heating material using electricity, a short circuit or a coating is lost to delay a fire. To prevent damage.

Since the upper surface of the MDF protective material is coated with an adhesive, and the peeling paper is attached, the peeling paper is removed when the finishing material is attached, and the finishing material is attached.

2-ethylhexyl acrylate is used as the main monomer, and acrylic acid and 2-hydroxyethyl methacrylate are used as the functional monomer, and the weight ratio is 2-ethylhexyl acrylate: acrylic acid: 2-heptyl acrylate Hydroxyethyl methacrylate = 88: 9: 3 in an epoxy crosslinking agent having a weight ratio of 0.6% by weight to the acrylic pressure-sensitive adhesive in a thickness of 25 ± 2 μm.

The acrylic adhesive and the epoxy cross-linking agent are mixed and applied and then aged in a dry oven at 50 ° C for 11-13 hours.

Usually, the pressure-sensitive adhesive is defined as a substance that exists between a substance or an object that is strongly and permanently bonded to at least two surfaces and enables bonding of the object. The pressure-sensitive adhesive used in the pressure-sensitive adhesive layer is a pressure-sensitive adhesive (PSA) And it is possible to adhere to the surface of another object with a small pressure such as low pressure without needing external force such as water, solvent, light, and heat in general and to easily adhere to the surface of another object Is defined as an adhesive that can be adhered by applying a very small pressure at a room temperature for a short time without using a falling adhesive, water, solvent, heat, and the like and can be peeled off from a hardened surface.

The pressure-sensitive adhesive of the present invention uses a solution polymerization method, in particular, a 9% by weight ratio of acrylic acid, which has a higher heat-resistant adhesive strength and minimizes a tensile rate and a shrinkage ratio, thereby enhancing the retention of bonding between the finish material and the MDF- The results are to be taken.

The following table shows the results obtained by using epoxy or isocyanate as the crosslinking agent, using butyl acrylate or 2-ethylhexyl acrylate as the main monomer, using 3 wt%, 6 wt%, or 9 wt% It is a comparison of thermal adhesive strength.

In the notation of the sample, it is shown that the kind of the main monomer and the weight ratio of acrylic acid, the crosslinking agent used are different, and the other functional monomer or aging condition, which is another condition, is the same.

Sample Peel Strengths (g / in) 20 minutes 24 hours Epoxy Using main monomer 2-ethylhexyl acrylate and using 3 wt% 92 200 Using main monomer 2-ethylhexyl acrylate and acrylic acid 6 wt% 106 351 Main monomer  2- Ethylhexyl Acrylate  Use and acrylic acid 9 wt% 409 588 Using main monomer butyl acrylate and using 3 wt% 66 122 Using main monomer butyl acrylate and acrylic acid 6 wt% 92 307 Using main monomer butyl acrylate and acrylic acid 9 wt% 312 402 Isocyanate Using main monomer 2-ethylhexyl acrylate and using 3 wt% 28 37 Using main monomer 2-ethylhexyl acrylate and acrylic acid 6 wt% 105 168 Using main monomer 2-ethylhexyl acrylate and acrylic acid 9 wt% 148 267 Using main monomer butyl acrylate and using 3 wt% 19 24 Using main monomer butyl acrylate and acrylic acid 6 wt% 87 100 Using main monomer butyl acrylate and acrylic acid 9 wt% 81 145

In Table 1, the use of the main monomer 2-ethylhexyl acrylate shown in Table 1 and the sample marked with 3% by weight of acrylic acid were described with respect to the pressure sensitive adhesive according to the present invention, and the main monomer was much stronger in adhesion than butyl acrylate, The strength of the heat-resistant adhesive force was found to be larger than that of using an isocyanate. The strength of the heat-resistant adhesive force minimizes the relaxation and shrinkage of the protective material and the finishing material located on the top of the heating material in the heating of the heating material and prevents the reduction of the adhesive force due to heat generation to maintain the optimum state, .

As described above, in the heating structure for preventing the height difference of the floor finishing materials according to the present invention, the MDF protective material made of the MDF material is installed on the top of the heating material, and the peeling paper, which is the finishing material, The MDF protection material is provided with a flame retardant impregnated with a flame retardant so as to prevent flaking of the flame retardant due to external force, The performance is high and the adhesive is coated on the outer surface of the MDF protective material so that the durability which can be generated by the heating element can be prevented.

While the present invention has been described with reference to the particular embodiments and drawings, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, Various modifications and variations are possible.
