産業上の利用分野
本発明は、耐湿性、上水性、撥油性が要求される厨房関
連機器等に応用する非粘着性を有する多孔体に関する。DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a porous body having non-adhesive properties that can be applied to kitchen-related equipment and the like that require moisture resistance, water repellency, and oil repellency.
従来の技術
従来、非粘着性を付与するには適用箇所に非粘着性化合
物を含む被膜を形成してきた。基材は鉄系、ステンレス
系などの板状の構造材料である。BACKGROUND OF THE INVENTION Conventionally, in order to impart non-adhesive properties, a film containing a non-adhesive compound has been formed at the application site. The base material is a plate-shaped structural material such as iron or stainless steel.
このような構成のものが、箱型の調理器庫内壁や調理用
受皿に応用され、付着した汚れの拭きとりやすさを訴求
していた。Products with this structure were applied to the inner walls of box-shaped cooking appliances and cooking trays, with the aim of making it easier to wipe away dirt.
発明が解決しようとする課題
しかしながら上記従来の技術においては、商品形状が平
板状であるために付着物との接触面積が大きくなること
と、被膜のピンホールの存在から付着物中の汚染性物質
が浸透し、外観上じみとして残る課題があった。Problems to be Solved by the Invention However, in the above conventional technology, since the product is flat, the contact area with deposits is large, and the existence of pinholes in the coating makes it difficult to detect contaminants in deposits. There was an issue that the problem was that it permeated and remained as a blemish on the exterior.
本発明はこのような課題を解決し、従来よりも優れた非
粘着性を有する多孔体の提供を目的とする。The present invention aims to solve these problems and provide a porous body having better non-adhesive properties than conventional ones.
ｉｌＭを解決するための手段
上記課題を解決するために本発明は、無機繊維の不織布
または織布のような高多孔率を有する多孔体の空隙部に
塊状の非粘着性化合物を保持させるかまたは前記多孔体
を形成している無機繊維の表面に非粘着性化合物を含む
被膜を形成して非粘着性を有する多孔体とするものであ
る。Means for Solving IlM In order to solve the above problems, the present invention involves holding a bulk non-adhesive compound in the voids of a porous body having a high porosity such as a non-woven fabric or a woven fabric made of inorganic fibers, or A coating containing a non-adhesive compound is formed on the surface of the inorganic fibers forming the porous body to make the porous body non-adhesive.
作用 以下、上記手段の作用について説明する。action The operation of the above means will be explained below.
一般に任意物体の表面に水、油等の液体が付着した場合
、中でも表面張力が大きい水は、その表面張力のために
表面積を最小にするように球状になろうとする。例えば
平板の上であれば、よく見られるように半球状となり、
液体は平板とある程度の接触面積をもつようになる。平
板の表面が非粘着性であっても、これは避けられない。Generally, when a liquid such as water or oil adheres to the surface of an arbitrary object, water, which has a high surface tension, tends to assume a spherical shape so as to minimize its surface area due to its surface tension. For example, if it is on a flat plate, it will be hemispherical, as is often seen.
The liquid comes to have a certain amount of contact area with the flat plate. This is unavoidable even if the surface of the plate is non-stick.
しかしながら、無機繊維と非粘着性化合物からなる多孔
体においては、上記接触面積が大幅に低下し、その結果
液体は半球状から殆ど球状になってしまう。However, in a porous body made of inorganic fibers and a non-adhesive compound, the above-mentioned contact area is significantly reduced, and as a result, the liquid changes from a hemispherical shape to an almost spherical shape.
これにより上記した課題はなくなり、付着物を残すこと
なく排除することができる。This eliminates the above-mentioned problem and allows removal without leaving any deposits.
実施例 以下、図面を用いて本発明の一実施例を説明する。Example An embodiment of the present invention will be described below with reference to the drawings.

ダとしてポリエーテルサルフメーンを用いた。Figure 1 is a cross-sectional view of a porous body in which polytetrafluoroethylene fine powder is held in the voids of a nonwoven fabric made of inorganic fibers whose main components are silicon oxide (silica) and aluminum oxide (alumina). ) is a porous material with a coating containing polytetrafluoroethylene formed on the surface of fibers mainly composed of silica and alumina, and the same [F (
FIG. 3 is an enlarged sectional view of the main part of FIG. In the figure, 1 is the above-mentioned inorganic fiber, 2 is the polytetrafluoroethylene fine powder, 3 is the above-mentioned coating, and 4 is the water droplet. Here, the diameter of the fiber of silica and alumina as main components is approximately 2 μm, and the length is several 1
The polytetrafluoroethylene fine powder 2 having an average primary particle diameter of about 1 μm was used as the binder for the coating 3.

８は水滴である。As is clear from FIGS. 1 and 2, the contact area between the water droplets 4 and the non-adhesive porous body is extremely small, and the droplets are mostly spherical, making them easy to remove. On the other hand, with only the conventional non-adhesive coating shown in FIG. 3, the water droplets become hemispherical and are more difficult to remove than with the present invention. In FIG. 3, 5 is polytetrafluoroethylene, 6 is a binder, 7 is a base material,
8 is a water droplet.

The R fibers may be made of zirconium oxide, glass, silicon carbide, or carbon other than warp/alumina, or may be made of either nonwoven fabric or woven fabric. In addition, polytetrafluoroethylene partially substituted with fluorine can also be used as it has non-adhesive properties, and the binder for film formation is mainly composed of polytetrafluoroethylene and polyphenylene sulfide or polysiloxane, which stain well. Silicone resin may also be used.
