Description

  The present invention relates to a mounting structure for a decorative panel using a magnetic sheet.

  In the past, when a decorative panel was applied to the base, it was bonded using an adhesive, but in recent years there has been a demand for easy installation without using an adhesive and for detachable installation, and a method that satisfies this need There is a method of screwing. However, screwing is extremely difficult because the decorative plate is damaged. As a means for solving such a problem, there is a method using Velcro (registered trademark). In this method, male and female tapes are joined. Although it is too strong and it is impossible to align while correcting subtle deviations, it must be repeatedly attached and detached, and it becomes more difficult as the area increases, On the contrary, it required skill.

  As a method for solving such a problem, a method using a magnet is conceivable. However, the center portion may be recessed or raised due to the expansion or contraction of the decorative panel due to the influence of temperature and humidity. Further, the magnet may be partially removed due to the warping of the decorative panel. Furthermore, there was a problem that the displacement could not be corrected after the construction. This is because the magnetic force is too strong to absorb the lateral displacement. However, if the magnetic force is weak, the decorative panel cannot be held, and there is a problem that the force is weak.

The present invention has been studied in view of such a situation, and provides a structure that can absorb vertical and horizontal misalignment when a decorative panel is magnetically attached to a base with a magnet, and has the following characteristics.
That is, according to the first aspect of the present invention, the decorative panel 1 is magnetically attached to the base 9 via the magnetic sheet 5 and the magnetic adherend 8 and is slid between the magnetic sheet 5 and the magnetic adherend. It is the attachment structure of the decorative panel 1 characterized by interposing the mobility treatment layer 3.
The invention described in claim 2 is the attachment structure of the decorative panel 1 according to claim 1, wherein the slidable treatment layer 3 is 3 mm or less.
Furthermore, the invention according to claim 3 is the attachment structure for the decorative panel 1 according to claim 1 or 2, wherein the slidable treatment layer 3 is a release paper.

  The structure of the present invention does not dent, rise or fall off even if the decorative panel expands or contracts due to the influence of temperature, humidity, etc., is easy to construct and disassemble, does not generate dust, and is dry. It can be carried out.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
Example 1
FIG. 1 is an exploded sectional view showing a structure for attaching a decorative panel 1 of the present invention to a base 9. The magnetic sheet 5 is interposed between the base 9 and the decorative panel 1, and the magnetic adherends 8 and 8 ′ are interposed between the base 9 and the magnetic sheet 5 and between the decorative panel 1 and the magnetic sheet 5. Has been.

  Further, a release paper in which a silicone resin is applied to the surface of a base material such as kraft paper or film is interposed between the magnetic adherend 8 ′ on the base 9 side and the magnetic sheet 5 as a slidable treatment layer 3. The decorative panel 1 can absorb the expansion and contraction due to the sliding movement in the vertical direction and the horizontal direction, temperature, humidity and the like. As the slidability treatment layer 3, oil, grease, carbon powder, composite plating such as chrome plating, nickel plating, fluorine coating, graphite, molybdenum disulfide, boron nitride is applied to the base material. Things can be used.

  As the decorative panel 1, a melamine resin decorative board having a thickness of 3 mm is used. Other than the melamine resin decorative board, there is no particular limitation as long as it has design properties, water resistance, heat resistance, and rigidity. Or decorative boards, such as a polyester resin decorative board and a diallyl phthalate resin decorative board obtained by film-forming using unsaturated polyester resin, are applicable. Desirably, it is preferable to use a cast or a melamine resin decorative board that has excellent performance in stain resistance and abrasion resistance and is not easily damaged.

As the magnetic adherends 8 and 8 ', those subjected to rust prevention treatment are desirable from the viewpoint of durability and cost, and surface treated steel sheets obtained by rust prevention treatment on the surface of steel sheets, specifically, electrogalvanized steel sheets ( Bonded steel sheet manufactured by Nippon Steel Corporation) is used. Other surface-treated steel sheets include hot dip galvanized steel sheets, alloyed hot dip galvanized steel sheets, hot dip galvanized steel sheets such as hot dip galvanized steel sheets, electrogalvanized steel sheets, electric double layer alloy galvanized steel sheets, electric Examples thereof include electrogalvanized steel sheets such as organic organic coated steel sheets, turn-plated steel sheets, and electrotin-plated steel sheets, all of which prevent the generation of rust due to moisture.
The adherends 8 and 8 ′ are attached to the back surface of the decorative panel 1 and the surface of the base 9 using a double-sided adhesive tape or an adhesive 7.

  As the adhesive 7, a cyano adhesive, urethane adhesive, modified silicone adhesive, epoxy adhesive, or the like can be used.

  A rare earth magnet sheet is used as the magnetic sheet 5. In addition to rare earth magnets, magnets include ferrite magnets and alnico magnets. However, the larger the decorative plate size, the heavier the thickness, the higher the magnetic force required. Rare earth magnets having a higher magnetic flux density than magnets and alnico magnets are particularly preferred.

  Rare earth magnets are scandium, yttrium, lanthanum, cerium, praseodymium, neodymium, promethium, samarium, eurobium, gadolinium, terium, dysprodium, holmium, erbium, thulium, ytterbium, lutetium, and other rare earth metals mixed with magnetic materials. The magnetic sheet 5 is obtained by kneading and softening a rare earth-based magnetic powder, a resin binder such as a synthetic rubber or a thermoplastic synthetic resin, a coupling agent, a vulcanizing agent, an anti-aging agent and the like. , Formed into a sheet by extrusion molding, injection molding, calendar molding, etc., and applied with a magnetic field.

  The particle size of the rare earth magnetic powder is preferably 20 to 150 μm, and the blending ratio is preferably 75 to 95% by weight. When the particle size is small, the magnetic properties are likely to deteriorate, and when the particle size is large, the orientation of the magnet powder is deteriorated. The greater the proportion, the better the magnetic properties, but if it exceeds 95% by weight, the magnetic sheet 5 becomes brittle.

  As the rare earth magnetic powder, those having a large residual magnetic flux density, coercive force, and maximum energy product are particularly preferable. In the present invention, a neodymium-iron-boron system is used.

  Synthetic rubbers include nitrile rubber, nitrile-butadiene rubber, silicone rubber, urethane rubber, fluorine rubber, acrylic rubber, butyl rubber, etc., and thermoplastic synthetic resins include vinyl chloride elastomer, styrene elastomer, olefin Examples of such elastomers include polyester elastomers, polyester elastomers, polyamide elastomers, and urethane resins. In the present invention, nitrile-butadiene rubber is used.

  In FIG. 1 showing Example 1, the slidable treatment layer 3 is interposed between the magnetic adherend 8 on the base 9 side and the magnetic sheet 5, but the magnetic adherence on the decorative panel 1 side. The slidable treatment layer 3 may be interposed between the body 8 and the magnetic sheet 5, or may be interposed in both. It is appropriately adjusted by the magnetic force and the shrinkage of the decorative panel 1.

An evaluation result is shown.
The structure shown in FIG. 1 was allowed to stand at 40 ° C.-90% RH for 3 days, and further allowed to stand at 40 ° C.-30% RH for 3 days.
As a comparative example, in FIG. 1, a sample that did not use the slidable treatment layer 3 was tested under the same conditions, but the center portion was raised.

FIG. 3 is an exploded configuration cross-sectional view showing a decorative panel mounting structure of the present invention.
