However, a technology has been disclosed to uniformly heat food using the far-infrared rays radiated from it. Ru. In addition, Japanese Patent Application Laid-Open No. 61-142163 discloses an intermediate layer of an instant food container. By using ceramics, we can take advantage of the far-infrared penetrating power of ceramics. A technique has been disclosed for preventing temperature changes in food stored therein.
【０００４】 上記の技術は、その目的とする用途には適しているが、支持体上に直接遠赤外 線放射物質層を設けると、加熱された遠赤外線放射物質は、遠赤外線をあらゆる 方向に放射するため、支持体自身が遠赤外線を吸収してしまい、その結果、食品 に吸収される遠赤外線の量が減少してしまうという問題があった。0004 Although the above technique is suitable for its intended application, it When a layer of radiation emitting material is provided, the heated far-infrared emitting material emits all far-infrared rays. The support itself absorbs the far infrared rays, and as a result, the food There was a problem in that the amount of far infrared rays absorbed by the infrared rays decreased.
【０００５】[0005]
従って、本考案は、上記の問題を解決した電子レンジ用加熱シートを提供する ことを目的とする。 さらに、本考案は、電子レンジのマイクロ波による金属の発熱により、より効 率的な電子レンジ用加熱シートを提供することも目的とする。 Therefore, the present invention provides a heating sheet for microwave ovens that solves the above problems. The purpose is to Furthermore, this invention is more effective due to the heat generation of metal by microwaves in microwave ovens.

The amount of far-infrared rays that is reflected back toward the food and radiated to the food increases. Furthermore, if the metal thin film layer is made thick enough to generate heat using microwaves, it will emit far infrared rays. The amount of heat added to the radiation material layer increases, making it possible to impart even more far-infrared rays to food. This led to the completion of this invention.

【００１２】 上記金属薄膜保護層は、例えば、ロールコーター、グレードコーター、エアナ イフコーター等による塗布、デイップ法、スプレー塗布法等の公知のいかなる方 法によっても、形成することができる。 上記金属薄膜層または上記金属薄膜保 護層の上には、遠赤外線放射物質層を積層する。遠赤外線放射物質層は、遠赤外 線放射物を含む。上記遠赤外線放射物の例としては、アルミナ（Ａｌ2 Ｏ3 ）、 ジルコニア（ＺｒＯ2 ）、ムライト（３Ａｒ2 Ｏ3 ・ＳｉＯ2 ）、コーデイライ ト（２ＭｇＯ・２Ａｌ2 Ｏ3 ・５ＳｉＯ2 ）、チタニア（ＴｉＯ2 ）、スチアタ イトシリカ（ＭｇＯ・ＳｉＯ2 ）、シリカアルミナ等の酸化物セラミック、炭化 ケイ素（ＳｉＣ）、炭化タングステン（ＷＣ）、炭化ジルコニウム（ＺｒＣ）等 の炭化物セラミック、窒化チタン（ＴｉＮ）、窒化ケイ素（Ｓｉ2 Ｎ4 ）等の窒 化物セラミック、ホウ化ジルコニウム（ＺｒＢ2 ）、ホウ化チタン（ＴｉＢ2 ） 等のホウ化セラミク、ケイ化タングステン（ＷＳｉ2 ）等のケイ化セラミックを 挙げることができる。上記の遠赤外線放射物は、それ自体を上記金属薄膜層また は、上記金属薄膜保護層の上に付着させても、あるいはまた、シート形成物質を 用いて付着させてもよい。上記シート形成物質は、遠赤外線放射物質を練り込む ことができ、シート化することができ、遠赤外線の透過率がよく、電子レンジ加 熱に耐え得るものであればよく、例えば、ポリプロピレン、ポリエチレンテレフ タレート等を挙げることができる。このようなシート形成物質に遠赤外線物質を 練り込む場合、シート形成物質に対する遠赤外線放射物質の含有量は、シート形 成物質１００重量部に対して１０〜１００重量部である。これより、遠赤外線放 射物の含有量が多いと、シート成形を困難にし、また、フイルム自身の柔軟性も 失われてしまうので好ましくなく、これより、遠赤外線放射物の含有量が少ない と、遠赤外線が、フイルム自身に吸収されてしまうので好ましくない。このうち 、１０〜５０重量部であることが好ましい。[0012] The metal thin film protective layer can be formed by any known method such as coating with a roll coater, grade coater, air knife coater, etc., a dip method, and a spray coating method. A far-infrared emitting material layer is laminated on the metal thin film layer or the metal thin film protective layer. The far-infrared emitting material layer contains far-infrared emitting material. Examples of the above-mentioned far-infrared radiators include alumina (Al 2 O 3 ), zirconia (ZrO 2 ), mullite (3Ar 2 O 3 ·SiO 2 ), cordierite (2MgO · 2Al 2 O 3 ·5SiO 2 ), and titania. Oxide ceramics such as (TiO 2 ), schiatite silica (MgO/SiO 2 ), and silica alumina, carbide ceramics such as silicon carbide (SiC), tungsten carbide (WC), and zirconium carbide (ZrC), and titanium nitride (TiN). ), nitride ceramics such as silicon nitride (Si 2 N 4 ), boride ceramics such as zirconium boride (ZrB 2 ), titanium boride (TiB 2 ), and silicide ceramics such as tungsten silicide (WSi 2 ). can be mentioned. The far-infrared emitter may itself be deposited on the metal thin film layer or the metal thin film protective layer, or alternatively, it may be deposited using a sheet-forming material. The sheet-forming material may be any material that can incorporate a far-infrared emitting material, can be formed into a sheet, has good far-infrared transmittance, and can withstand heating in a microwave oven, such as polypropylene, polyethylene terephthalate, etc. etc. can be mentioned. When kneading a far-infrared material into such a sheet-forming material, the content of the far-infrared emitting material in the sheet-forming material is 10 to 100 parts by weight per 100 parts by weight of the sheet-forming material. If the content of far-infrared rays is too high, it becomes difficult to form a sheet and the film itself loses its flexibility, which is undesirable. This is undesirable because far infrared rays are absorbed by the film itself. Of these, it is preferably 10 to 50 parts by weight.
【００１３】 上記の遠赤外線放射物層は、細孔を有していてもよい。細孔は、食品からにじ みでた水分の吸収及び拡散を助けることができる。これらの孔は、遠赤外線放射 物層のシート１ｃｍ2 当たり１〜１００個設けられていることが好ましい。 上記の遠赤外線放射物層は、例えば、押出法、延伸法、等の公知のいかなる方 法によっても形成することができる。[0013]The above-mentioned far-infrared emitter layer may have pores. The pores can help absorb and diffuse moisture exuded from the food. Preferably, 1 to 100 of these holes are provided per 1 cm 2 of the sheet of the far-infrared emitter layer. The above-mentioned far-infrared emitter layer can be formed by any known method such as extrusion or stretching.

You can also start. Examples of the above overcoat layer include silicone resin, acrylic resin, etc. can be done.
【００１５】 上記のオーバーコート層は、遠赤外線放射物質層を保護することと食品に直接 触れないということを目的としているので、遠赤外線を吸収しないことが望まし く、従って、厚さは、薄ければ薄いほど好ましい。具体的には１μｍ以下である ことが好ましい。[0015] The above overcoat layer can protect the far infrared emitting material layer and directly contact the food. Since the purpose is not to touch it, it is desirable that it does not absorb far infrared rays. Therefore, the thinner the thickness is, the more preferable it is. Specifically, it is 1 μm or less It is preferable.
