Description
本発明は、遠赤外線を放射し、抗菌性と柔軟性を有する遠赤外線放射シートに関する。 The present invention relates to a far-infrared radiation sheet that emits far-infrared rays and has antibacterial properties and flexibility.
波長３〜１０００ミクロンの遠赤外線は身体の深部に達し、皮下組織の温度上昇、微細血管の拡張、血液循環の促進、血液と人体と他の組織間の新陳代謝などにより筋肉の凝り、張り、痛みなどの鎮静、鎮痛効果が発揮される。この効果を求めて、遠赤外線放射サウナや遠赤外線ランプ、各種の遠赤外線シートなどが使用されている。 Far-infrared rays with a wavelength of 3 to 1000 microns reach the deep part of the body, causing muscle stiffness, tension, and pain due to increased temperature of the subcutaneous tissue, expansion of microvessels, promotion of blood circulation, metabolism between blood, human body and other tissues, etc. The sedative and analgesic effects are demonstrated. In search of this effect, far-infrared radiation saunas, far-infrared lamps, various far-infrared sheets and the like are used.
遠赤外線を放射する物質としてはブラックシリカ、トルマリン、麦飯石、黒曜石などの鉱物や金属酸化物として酸化アルミニウム、酸化ジルコニウム、酸化ニッケル、酸化チタン、酸化鉄、酸化シリコン、酸化マグネシウムなどがあり、これらの単独物質あるいは混合物が遠赤外線放射微粒子として使われる。 Materials that emit far infrared rays include minerals such as black silica, tourmaline, barley stone, obsidian, and metal oxides such as aluminum oxide, zirconium oxide, nickel oxide, titanium oxide, iron oxide, silicon oxide, and magnesium oxide. A single substance or a mixture of these is used as far-infrared radiation fine particles.
遠赤外線効果を生かすために遠赤外線放射微粒子を様々な熱可塑性樹脂や熱硬化性樹脂に練込み繊維状あるいはシート状に加工したり、遠赤外線放射微粒子を包含する樹脂を対象物に吹き付け固化させるなどして利用している。 In order to take advantage of the far-infrared effect, far-infrared radiation fine particles are kneaded into various thermoplastic resins and thermosetting resins and processed into fibers or sheets, or a resin containing far-infrared radiation fine particles is sprayed and solidified on an object. Etc. are used.
各種の樹脂に固形物としての遠赤外線放射微粒子を包含させて放射される遠赤外線を利用する場合、赤外線放射微粒子の含有率高いほど遠赤外線放射が強くなり好ましいが、熱可塑性樹脂を使用した製品では、柔軟性や強度を求めると固形物微粒子含有率としては５０質量％が限度となる。エポキシ樹脂などの熱硬化性樹脂に包含させると、熱硬化性樹脂の高い強度が固形物微粒子を強固に保持するため７０質量％以上の高い含有率を得ることが出来、遠赤外線の放射率も高くなるが、弾性や柔軟性は失われる。 When using far-infrared rays that are radiated by including far-infrared radiation particles as solids in various resins, the higher the content of infrared radiation particles, the stronger the far-infrared radiation, which is preferable, but products using thermoplastic resins Then, when a softness | flexibility and intensity | strength are calculated | required, 50 mass% becomes a limit as solid content rate. When included in a thermosetting resin such as an epoxy resin, the high strength of the thermosetting resin firmly holds the solid particles, so that a high content of 70% by mass or more can be obtained, and the emissivity of far infrared rays is also high. Higher, but loses elasticity and flexibility.
本発明は。遠赤外線放射微粒子の高い含有率により遠赤外線の放射率を高め、効率的に利用するために皮膚に貼ったり皮膚表面近くに置くことができるよう、皮膚の曲面形状に追随できる柔軟性があり、皮膚と密着したシートとの間の雑菌の繁殖を抑制可能な抗菌性を有する遠赤外線放射シートを提供する。 The present invention. Increased far-infrared emissivity due to the high content of far-infrared radiation fine particles, has the flexibility to follow the curved shape of the skin so that it can be applied to the skin or placed near the skin surface for efficient use, Disclosed is a far-infrared radiation sheet having antibacterial properties capable of suppressing the propagation of germs between a sheet and a sheet in close contact with the skin.
遠赤外線放射微粒子の含有率を高め強固に保持する合成樹脂としてシリコーンレジンを用いる。シリコーンレジンはシロキサン結合（Ｓｉ−Ｏ−Ｓｉ）でつながっていて、３官能性（１個のケイ素原子を中心に１個のメチル基、又はフェニル基、又はビニル基などと３個の酸素原子の結合）または４官能性（１個のケイ素原子を中心に４個の酸素原子の結合）の結合から縮合反応を進めて高分子量のシリコーンレジンが作られる。ケイ素と酸素の繰り返しからなるシロキサン結合が３次元化した基本骨格をしており、炭素からなる結合でできている有機系の樹脂などと比較して、ケイ素と酸素の結合は原子同士の結びつきが強いため、シリコーンレジンは固形物微粒子を強固に保持し含有率を高めることができる。 Silicone resin is used as a synthetic resin that increases the content of far-infrared radiation fine particles and holds it firmly. Silicone resins are linked by siloxane bonds (Si-O-Si), and are trifunctional (one methyl group, one phenyl group, one vinyl group, etc., and three oxygen atoms centered on one silicon atom). Bond) or a tetrafunctional bond (bond of four oxygen atoms centered on one silicon atom) to proceed a condensation reaction to produce a high molecular weight silicone resin. The siloxane bond consisting of repeating silicon and oxygen has a three-dimensional basic skeleton. Compared to organic resins made of carbon bonds, the bond between silicon and oxygen has a bond between atoms. Since it is strong, the silicone resin can firmly hold solid particles and increase the content.
シリコーンレジンは強度に優れるが硬く柔軟性に欠ける。そこで柔軟性に富むシリコーンゴムシートの表面にシリコーン接着層を薄く形成し、この層の上に遠赤外線放射微粒子を高い含有率で含むシリコーンレジンの薄い層を形成し、これら３層を一体化した遠赤外線放射シートを作成する。３層が一体化したシートは、相対的に厚く柔軟性のあるシリコーンゴムシートがシートとしての柔軟性を発揮し、シリコーンレジン層が高い遠赤外線放射率を発揮する。 Silicone resins are excellent in strength but hard and lack flexibility. Therefore, a thin silicone adhesive layer is formed on the surface of the flexible silicone rubber sheet, a thin layer of silicone resin containing a high content of far-infrared radiation particles is formed on this layer, and these three layers are integrated. Create a far-infrared radiation sheet. In a sheet in which three layers are integrated, a relatively thick and flexible silicone rubber sheet exhibits flexibility as a sheet, and a silicone resin layer exhibits high far-infrared emissivity.
本発明によるシートを皮膚に貼ると、皮膚とシートとの間で雑菌が繁殖する可能性があるので、抗菌性の高い銀微粒子をシリコーンレジンに含有させ雑菌の繁殖を抑制する。 When the sheet according to the present invention is applied to the skin, there is a possibility that various germs will propagate between the skin and the sheet. Therefore, silver fine particles having high antibacterial properties are contained in the silicone resin to suppress the propagation of germs.
本発明によるシートを肩こり、筋肉痛、打撲などの患部に粘着シートで貼り症状を改善することが期待できる。またこむらがえりによるふくらはぎの激痛の緩和や、足の裏のツボの刺激にも効果があり、非常に有用性が高い。このシートは、皮膚に貼ることにより付着した皮脂や汗の成分などを洗剤などで洗い流して繰り返し使用することが出来る。 The sheet according to the present invention can be expected to improve symptoms by sticking the affected area such as stiff shoulders, muscle pain, and bruise with an adhesive sheet. It is also very useful because it is effective in relieving severe calf pain caused by Komuragaeri and stimulating the pressure points on the soles of the feet. This sheet can be repeatedly used by washing away sebum and sweat components adhering to the skin with a detergent or the like.
本発明によるシートは、アイマスクや腹巻、コルセットなど身体に装着する製品の内側につけて強力な遠赤外線を利用することも可能である。 The sheet according to the present invention can be applied to the inside of a product to be worn on the body such as an eye mask, a stomach wrap, or a corset, and can utilize a strong far infrared ray.
本発明の実施例を説明する。 Examples of the present invention will be described.
厚さ１ｍｍの柔軟性に富むシリコーンゴムシートに、厚さ０．０８５ｍｍのシリコーン接着フイルム（（株）寺岡製作所製）を貼りつけシリコーン接着層を形成した。シリコーンレジン（信越化学工業（株）製）に８〜２５μｍのブラックシリカ微粒子を８０質量％充填し、更に粒子径４〜２５ｎｍの銀パウダーを５００ｐｐｍ配合してスプレーガンでシリコーン接着層の上に４０μｍの厚さに吹き付けた。このシートを２０分間の自然乾燥の後、１５０℃の温度で１０分間加熱した。この加熱によりシリコーンレジン層は固化し、シリコーンレジン層とシリコーン接着層、およびシリコーン接着層とシリコーンゴムシートの接着強度が増して、相互に強固に密着した３層よりなるシートが作成された。シリコーンゴムシート自体は耐熱温度が２００℃あり、この加熱により何ら影響されることなく柔軟性を保った。A silicone adhesive film (manufactured by Teraoka Seisakusho Co., Ltd.) having a thickness of 0.085 mm was attached to a 1 mm-thick flexible silicone rubber sheet to form a silicone adhesive layer. Silicone resin (manufactured by Shin-Etsu Chemical Co., Ltd.) is filled with 80% by mass of 8-25 μm black silica fine particles, and further 500 ppm of silver powder with a particle size of 4-25 nm is blended and 40 μm above the silicone adhesive layer with a spray gun. Sprayed to the thickness of. The sheet was naturally dried for 20 minutes and then heated at a temperature of 150 ° C. for 10 minutes. By this heating, the silicone resin layer was solidified, and the adhesive strength between the silicone resin layer and the silicone adhesive layer, and between the silicone adhesive layer and the silicone rubber sheet was increased, and a sheet composed of three layers firmly adhered to each other was produced. The silicone rubber sheet itself had a heat resistant temperature of 200 ° C., and was kept flexible without being affected by this heating.
実施例ではブラックシリカ微粒子を８０質量％充填させたが、充填量７０〜９０質量％の範囲であることが好ましい。 In the examples, 80% by mass of black silica fine particles was filled, but the filling amount is preferably in the range of 70 to 90% by mass.
実施例では遠赤外線放射層である表層に抗菌性を付与するため、日本イオン株式会社製ナノシルバー分散液ＴＸ−ＥＢ１４Ｈを５００ｐｐｍ配合した。この製品の抗菌性能については、抗菌試験法ＪＩＳ Ｚ ２８０１による２４時間後の菌数で、大腸菌、黄色ブドウ球菌、緑膿菌などの残留生菌数が１０以下となっている。（（社）京都微生物研究所にて検査）（日本イオン株式会社資料））。 In Example, in order to impart antibacterial properties to the surface layer which is a far infrared radiation layer, 500 ppm of Nippon Silver Co., Ltd. nano silver dispersion TX-EB14H was blended. Regarding the antibacterial performance of this product, the number of residual bacteria such as Escherichia coli, Staphylococcus aureus and Pseudomonas aeruginosa is 10 or less after 24 hours according to the antibacterial test method JIS Z 2801. (Tested at the Kyoto Microbiology Research Institute) (Nippon AEON Co., Ltd. data)).
実施例ではシリコーンレジン層は固化されて柔軟性を失っているが、シリコーンレジン層に密着したシリコーン接着層がシリコーンレジン層の亀裂剥離を防ぎ、他の層と比較して相対的に厚いシリコーンゴムシートが３層からなるシートの柔軟性を保持しているので、皮膚の曲面に密着して使用することが可能となった。 In the examples, the silicone resin layer is solidified and loses flexibility, but the silicone adhesive layer in close contact with the silicone resin layer prevents cracking of the silicone resin layer and is relatively thick compared to the other layers. Since the sheet retains the flexibility of the three-layer sheet, it can be used in close contact with the curved surface of the skin.
実施例ではフイルム状のシリコーン接着剤を使用したが、液状のシリコーン接着剤をスプレーガンで吹き付けたり、刷毛で塗り使用してもよい。 In the embodiment, a film-like silicone adhesive is used, but a liquid silicone adhesive may be sprayed with a spray gun or applied with a brush.
実施例では厚さ１ｍｍのシリコーンゴムシートを使用したが、この厚みに限ることなく、０，５ｍｍ〜２．０ｍｍ厚のシリコーンゴムシートでも使用可能である。 In the examples, a silicone rubber sheet having a thickness of 1 mm was used, but the present invention is not limited to this thickness, and a silicone rubber sheet having a thickness of 0.5 mm to 2.0 mm can also be used.
実施例ではシリコーンレジン層の厚さを４０μｍとしたが、２５〜５０μｍの厚さの範囲で形成することが好ましい。 In the examples, the thickness of the silicone resin layer is 40 μm, but it is preferably formed in the range of 25 to 50 μm.
