本発明はホウロウ引き浴槽、例えば、鋳物ホウロウ浴槽
の改良に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to improvements in enameled bathtubs, such as cast enameled bathtubs.
鋳物ホウロウ浴槽において、鋳物浴槽基材に不透明ホウ
ロウを焼付けたのち、このホウロウ層が溶融状態にある
間に化粧用の無機質粒子を散布し、その上に上塗用の透
明ホウロウを塗布し、次いで、再加熱によって、上塗ホ
ウロウを溶着（焼付け）することが知られている。In a cast enamel bathtub, opaque enamel is baked onto the cast bathtub base material, then cosmetic inorganic particles are sprinkled on the enamel layer while it is in a molten state, and a transparent enamel is applied as a top coat on top of it, and then, It is known that the top coat enamel is welded (baked) by reheating.
しかＬながら、か＼る鋳物ホウロウ浴槽においては、化
粧用無機質粒子にホウロウ融点より高融点のものを使用
する必要があり、この化粧用の無機質粒子層が基材直上
の不透明ホウロウ層と上塗用の透明ホウロウ層との間に
溶融されることなく介在するから、これら不透明ホウロ
ウ層と透明ホウロウ層との間に層間剥離が生じ易い。However, in such cast enameled bathtubs, it is necessary to use cosmetic inorganic particles with a melting point higher than the melting point of the enamel, and this cosmetic inorganic particle layer is in contact with the opaque enamel layer directly above the base material. Since the opaque enamel layer is interposed between the opaque enamel layer and the transparent enamel layer without being melted, delamination is likely to occur between the opaque enamel layer and the transparent enamel layer.
又、化粧用無機質粒子層が呈する外観も単調である。Moreover, the appearance of the cosmetic inorganic particle layer is also monotonous.
本発明に係るホウロウ引き浴槽は、上述の難点を解消し
得る構成であり、浴槽基材の表面に不透明ホウロウ層を
設け、該ホウロウ層表面にネオジム粉末の埋着層を設け
、更に、透明又は半透明のホウロウ層を設けたことを特
徴とするものである。The enameled bathtub according to the present invention has a structure that can solve the above-mentioned difficulties, and includes an opaque enamel layer provided on the surface of the bathtub base material, an embedded layer of neodymium powder on the surface of the enamel layer, and a transparent or It is characterized by having a translucent enamel layer.
以下、図面により本発明の一実施例を説明する。An embodiment of the present invention will be described below with reference to the drawings.
第１図において、１は鋳物浴槽基材である。In FIG. 1, 1 is a casting bathtub base material.
２は下グスリ層である。2 is the lower goose layer.
３は不透明なホウロウ層であり、浴槽基材１を加熱し、
この基材１の下グスリ層２上に不透明グスリ（例えば、
チタングスリ）をスプレー塗布し、これを基材温度で焼
付けたものである。3 is an opaque enamel layer, which heats the bathtub base material 1;
Opaque grease (for example,
Titanium paste) was spray applied and baked at the temperature of the base material.
この不透明ホウロウ層３により浴槽基材１の地色が遮ら
れる。This opaque enamel layer 3 blocks the background color of the bathtub base material 1.
４は不透明ホウロウ層３の表面に埋着したネオジム（融
点１０２４℃、比重７．０５、銀白色）の粉末層であり
、その形成には、上記不透明ホウロウ層３を、浴槽基材
１の再加熱によって溶融し、この溶融状態の不透明ホウ
ロウ層３の表面にネオジム粉末を散布する方法が用いら
れる。4 is a powder layer of neodymium (melting point 1024°C, specific gravity 7.05, silvery white) embedded on the surface of the opaque enamel layer 3. To form this, the opaque enamel layer 3 is reused in the bathtub base material 1. A method is used in which neodymium powder is melted by heating and then sprinkled on the surface of the opaque enamel layer 3 in this molten state.
ネオジムの粉末は、ホウロウに比べ比重が犬であるので
、第２図に示すように溶融状態のホウロウ層表面によく
埋着される（ネオジム粉末の散布は、傾動操作の自在な
枠に浴槽を納め、浴槽基材の粉末散布面を水平になすよ
うに、枠を操作しながら行う）。Since neodymium powder has a lower specific gravity than enamel, it is easily embedded in the surface of the molten enamel layer, as shown in Figure 2. (Do this while manipulating the frame so that the powder-spreading surface of the bathtub base material is level.)
５は透明又は半透明のホウロウ層であり、上記不透明ホ

より焼付けたものである。5 is a transparent or translucent enamel layer, which is obtained by spraying a transparent or translucent paste while the opaque enamel layer 3 is in a molten state, and then baking this by heating the bathtub base material again. be.
本発明に係るホウロウ引き浴槽は、上述した通りの構成
であり、内側ホウロウ層である不透明ホウロウ層の表面
にネオジム粉末が埋着されているから、その不透明ホウ
ロウ層と上塗りの透明乃至半透明のホウロウ層とを直接
に融着でき、これら層間での剥離を充分に防止できる。The enameled bathtub according to the present invention has the above-mentioned structure, and since neodymium powder is embedded in the surface of the opaque enamel layer, which is the inner enamel layer, the opaque enamel layer and the transparent or semi-transparent top coat. It can be directly fused to the enamel layer, and separation between these layers can be sufficiently prevented.
更に、ネオジム粉末が不透明ホウロウ層表面下に厚みを
有する層で散在しているから、透明又は半透明のホウロ
ウ層を透過した光は、不透明層表面に侵入し、ネオジム
粉末の散在層で乱反射して、深みのある銀白色を呈する
。Furthermore, since the neodymium powder is scattered under the surface of the opaque enamel layer in a thick layer, light that has passed through the transparent or semi-transparent enamel layer enters the surface of the opaque layer and is diffusely reflected by the neodymium powder scattered layer. It has a deep silvery white color.
