Description
本発明はプラスチック製製品に関し、特に湯水を貯めて使用することに用いられる比較的大型のプラスチック容器、例えば浴槽や貯水槽その他の製品の構造に関する。 The present invention relates to plastic products, and more particularly to the structure of relatively large plastic containers used for storing and using hot water, such as bathtubs, water tanks and other products.
従来より、浴槽、特にユニットバスはプラスチック、それも強化プラスチック（ＦＲＰ）により成形され、浴室の所定位置に設置固定される。また、貯水槽は特にマンションをはじめとする高層住宅の屋上等において設置され、一旦上水道水をポンプで汲み上げ貯めた水を各室に配給する構成となっている。 Conventionally, a bathtub, particularly a unit bath, is formed of plastic, which is also reinforced plastic (FRP), and is installed and fixed at a predetermined position in a bathroom. In addition, the water storage tanks are installed especially on the rooftops of high-rise houses such as condominiums, and the water that has been pumped up and stored once is distributed to each room.
ユニットバスの場合は、西洋式のバスタブとは異なり、使用者ごとに湯を流し汲み代えるものではなく、一旦貯めた湯を家族や同居人が何度も利用するシステムとなっており、ユニットバスそれ自体も保温を考慮してはいるが、通常は保温加熱装置によって貯めた湯が冷めることのないようにしている。 In the case of a unit bath, unlike a Western-style bathtub, it is not a system that allows hot water to be poured for each user, but is a system in which a family or cohabitant uses the hot water once stored. Although the thermal insulation itself is taken into consideration, the hot water stored by the thermal insulation heating device is usually kept from cooling.
また、マンション等の高層住宅の屋上等に設置される貯水槽は各室ごとへ上水道設備から汲み上げを行なうポンプのパワーや経費を抑えるとともに、地震等の緊急時における水源確保の意味合いもあるが、格別には貯められた水への衛生管理は配慮されず、時として無害とされる抗菌剤が投入される程度である。
本発明が解決しようとする問題点は、従来のプラスチック製製品、特に浴槽にあっては保温についての特性がなく電気やガスのエネルギーを用いることで保温をしなければならず、それに貯水槽等も加えて抗菌性に乏しく衛生的な面での保全がなし得なかったという点である。 The problem to be solved by the present invention is that conventional plastic products, particularly bathtubs, do not have heat retention characteristics and must be kept warm by using energy of electricity and gas, and water storage tanks, etc. In addition, it has poor antibacterial properties and could not be maintained in a hygienic manner.
上記した問題点を解決するために、本発明に係るプラスチック製製品は外面もしくは内面の一部または全面に、バインダーに混ぜ込んだセラミックス粉体を塗着してあることを特徴とし、前記したセラミックスは、酸化珪素を３０〜７０％、酸化アルミニウムを１０〜３０％、酸化カルシウムを３〜１０％、酸化クロムを０．１〜０．５％、酸化マンガンを０．０５〜０．２％、酸化鉄を３〜９％、酸化コバルトを０．０５〜２％、酸化カリウムを０．４〜２％、酸化ナトリウムを１〜６％、酸化マグネシウムを０．４〜２％の割合で配合し、残りを通常の不純物としたものを一旦粉砕し、水と混練して粘土状として塊状とし、乾燥後に焼成したものを粉状としてあることを特徴とし、前記したセラミックスには、トルマリンを１０〜７０％の割合で添加配合してあることを特徴とし、前記したセラミックスには、酸化チタンを５〜３０％の割合で添加配合してあることを特徴とし、前記したセラミックスの焼成温度は１００℃〜９００℃であることを特徴としている。 In order to solve the above-mentioned problems, the plastic product according to the present invention is characterized in that a ceramic powder mixed with a binder is coated on a part or the whole of the outer surface or the inner surface, 30-70% silicon oxide, 10-30% aluminum oxide, 3-10% calcium oxide, 0.1-0.5% chromium oxide, 0.05-0.2% manganese oxide, 3-9% iron oxide, 0.05-2% cobalt oxide, 0.4-2% potassium oxide, 1-6% sodium oxide, and 0.4-2% magnesium oxide. The remaining ceramics are once pulverized, kneaded with water to form a lump as clay, and dried and baked into powder. 70% It is characterized in that it is added and blended in proportions, and in the ceramics described above, titanium oxide is added and blended in a proportion of 5 to 30%, and the firing temperature of the ceramics described above is 100 ° C to 900 ° C. It is characterized by being.
また、本発明に係るプラスチック製製品は浴槽を対象としてあることを特徴とし、浴槽を対象として、その外側面から底面にバインダーに混ぜ込んだセラミックス粉体を塗着し、かつ、その対応する壁面、床面にも同様のバインダーに混ぜ込んだセラミックス粉体を塗着してあることを特徴とし、貯水槽を対象とし、少なくともその内面にバインダーに混ぜ込んだセラミックス粉体を塗着してあることを特徴とし、浴室の床面を対象とし、その表面にバインダーに混ぜ込んだセラミックス粉体を塗着してあることを特徴とし、便座を対象とし、その外表面にバインダーに混ぜ込んだセラミックス粉体を塗着してあることを特徴とし、トイレットペーパーのホルダーカバーの外表面にバインダーに混ぜ込んだセラミックス粉体を塗着してあることを特徴としている。 Further, the plastic product according to the present invention is intended for a bathtub, the ceramic powder mixed in the binder is applied from the outer surface to the bottom surface of the bathtub, and the corresponding wall surface The ceramic powder mixed with the same binder is also applied to the floor surface, and the ceramic powder mixed with the binder is applied at least to the inner surface of the water tank. Ceramics mixed with binder on the surface of the bathroom and coated on the surface of the bathroom, ceramics mixed with binder on the outer surface of the toilet seat The ceramic powder mixed with the binder is coated on the outer surface of the toilet paper holder cover. It is characterized in.
上記した構成としたことによって、浴槽や貯水槽をはじめとするプラスチック製製品にあって、塗着されたセラミックス粉体の特性から遠赤外線の放射によって保温性が大きく向上し、格別なエネルギーを消費することなく湯温を保つことができ、また、滅菌、殺菌を含めた意味での抗菌作用によって容器内に収容されている湯水及び製品容器自体を衛生的に保持することができることとなる。 By adopting the above configuration, in the plastic products such as bathtubs and water storage tanks, the thermal insulation is greatly improved by the radiation of far-infrared rays due to the characteristics of the coated ceramic powder and consumes special energy. Accordingly, the hot water temperature and the product container itself can be maintained hygienically by antibacterial action including sterilization and sterilization.
図面で示す実施例のように構成することで、前記した効果を得ることができるように実現した。 By configuring as in the embodiment shown in the drawings, the above-described effects can be obtained.
次に、本発明の好ましい実施の例を図面を参照して説明する。図１は対象を浴槽とした場合の部分断面図、図２は対象を貯水槽とした場合の部分断面図、図３は塗着工程を示すフローチャート図である。 Next, a preferred embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a partial cross-sectional view when the object is a bathtub, FIG. 2 is a partial cross-sectional view when the object is a water storage tank, and FIG. 3 is a flowchart showing the coating process.
これらの図にあって１はプラスチック、それも強化プラスチック（ＦＲＰ）で成形された浴槽を示している。この浴槽１は略２０ｃｍ程度の空隙Ｓを隔てて床材２と、図示しないスペーサーを介して設置固定される。 In these drawings, reference numeral 1 denotes a bathtub made of plastic, which is also made of reinforced plastic (FRP). The bathtub 1 is installed and fixed via a flooring 2 and a spacer (not shown) with a gap S of about 20 cm.
この実施例にあって浴槽１の外面、特に底面から側面にかけての部分における外面にはセラミックス粉体を主成分としたセラミックス層３が塗着されており、このセラミックス層３は空隙Ｓを隔てて対向する床材２の表面にも形成されている。 In this embodiment, a ceramic layer 3 mainly composed of ceramic powder is applied to the outer surface of the bathtub 1, particularly the outer surface from the bottom surface to the side surface, and the ceramic layer 3 is separated by a gap S. It is also formed on the surface of the facing flooring 2.
ここにおけるセラミックス層３は原料粉として主成分となる酸化珪素を約４０％以上、酸化アルミニウムを２０％とし、両者で全体の６０％以上とする。これに酸化カルシウムを約６％、酸化鉄（Ｆｅ2Ｏ3）を約６％、そして酸化ナトリウムを約３％配合し、酸化クロムを約０．３％、酸化マンガンを約０．１％、酸化コバルトを約０．１％、酸化カリウムを約１．０％、酸化マグネシウムを約１．０％配合し、残りに通常の不純物のほか、必要に応じてトルマリン及び酸化チタンをマイナスイオン発生剤として添加配合した。 Here, the ceramic layer 3 is composed of about 40% or more of silicon oxide as a main component and 20% of aluminum oxide as a raw material powder, and 60% or more of both. About 6% calcium oxide, about 6% iron oxide (Fe 2 O 3 ), and about 3% sodium oxide, about 0.3% chromium oxide, about 0.1% manganese oxide, About 0.1% cobalt oxide, about 1.0% potassium oxide, and about 1.0% magnesium oxide are added. In addition to normal impurities, tourmaline and titanium oxide are added as necessary to generate negative ions. As an additive.
この原料粉は複数の硬質なアルミナボールと共にボールミルに入れ、回転させることで粉砕する。この粉砕された原料粉はフルイによって粒子ごとの選定をするが、このフルイで選定不能な細かいものは水に溶かしてけん濁液とし、沈殿させて得ることができる。 This raw material powder is put into a ball mill together with a plurality of hard alumina balls and pulverized by rotating. The pulverized raw material powder is selected for each particle by using a sieve. Fine powder that cannot be selected by this sieve can be obtained by dissolving in water to form a suspension and precipitating.
この段階で粉体をバインダー（接着剤）に投入混練して使用することもできるが、セラミックスとしての特性をさらに高めるため、一担成形後に再度粉砕して使用することもできる。この場合には前記した選定された粉体を混練装置によって水とともに練り上げ、粘土状とし、この粘土状としたものを適宣サイズの塊状に塑形する。 At this stage, the powder can be charged and kneaded into a binder (adhesive) and used. However, in order to further improve the characteristics as a ceramic, it can be used after being pulverized again after one-part molding. In this case, the selected powder is kneaded with water by a kneading device to form a clay, and the clay is molded into an appropriately sized lump.
この塊状に塑形したものを乾燥させて後に焼成することとなるが、酸化珪素の含有量が多い場合には必要温度は高いものとなり、いわゆる磁器となる。この高温による焼成によって乾燥状態の粒子同士が結合して固化することとなる。焼成温度は本実施例では酸化珪素の含有量の多さから９００℃近い高温が望まれるが、この焼成温度は原料の配合比率によって変わるものとなる。 This lump-shaped plastic is dried and fired later, but when the silicon oxide content is high, the required temperature becomes high and a so-called porcelain is obtained. By firing at this high temperature, the dried particles are bonded and solidified. In this embodiment, the firing temperature is preferably a high temperature close to 900 ° C. because of the high content of silicon oxide, but this firing temperature varies depending on the blending ratio of the raw materials.
こうして焼成された物（セラミックス）は、本実施例の場合、非常に原料粒子の結合度が強く、粒子間に残る隙間は少ないものとなっており、水分の浸入等による劣化のおそれはなく、そのまま使用に耐えられるものである。また、セラミックス層３の形成には格別必要はないが、焼成されたセラミックスをそのまま使用する場合には表面の見栄えのために釉薬を塗ることもでき、この場合の釉薬も前記した配合の実施例のもので済むが、焼成前に塗布する場合には酸化珪素の量を減らして溶融温度を下げ、ガラス状となるようにする。 In the case of this example, the fired product (ceramics) has a very strong bond between the raw material particles, and there are few gaps remaining between the particles, and there is no risk of deterioration due to moisture ingress, etc. It can be used as it is. Although it is not particularly necessary to form the ceramic layer 3, when the fired ceramic is used as it is, the glaze can be applied for the appearance of the surface. However, when it is applied before firing, the amount of silicon oxide is reduced to lower the melting temperature so that it becomes glassy.
前記した釉薬も硬化後は耐衝撃性に優れたものとなり、また、製品表面の粒子反応して接合状態となり、剥離することなく、強制的な削り落としにも耐えるものとなる。 The above-mentioned glaze also has excellent impact resistance after curing, and also reacts with particles on the product surface to be in a bonded state, and can withstand forced scraping without peeling.
前記したセラミックス層３を得るためにはこの成形化されたセラミックスを再度粉砕して粒子結合度のよいセラミックス粉体を得ることとなるが、焼成後の成形状態のセラミックスを身飾品等として装着した場合、着用後略３０分の経過でサーモスタットはその温度上昇を示す赤色となり、更に、通常は表出しないピンク色から白色にまで変化した。これは血行が著しく促進されたこと、換言すると有効な遠赤外線が大量に放射されていることを示している。また、痛みを有する患部に貼装したところ、その痛みがやわらぎ、数日の着用で痛みが解消した。 In order to obtain the ceramic layer 3 described above, the formed ceramic is pulverized again to obtain a ceramic powder having a good particle bonding degree. In this case, the thermostat turned red indicating an increase in temperature after about 30 minutes after wearing, and further changed from pink, which does not normally appear, to white. This indicates that blood circulation has been significantly promoted, in other words, a large amount of effective far-infrared radiation has been emitted. Moreover, when it was affixed to the affected part which has a pain, the pain was soft, and the pain was eliminated by wearing for several days.
さらに、カップや皿等の食器を成形して、飲料や食品を入れたところ、アルコール飲料をはじめ、茶やコーヒー等の嗜好品にあっても味は非常にまろやかとなり、食品の腐敗進行も遅れるものとなった。 Furthermore, when tableware such as cups and dishes is molded and beverages and foods are added, the taste becomes very mellow even for luxury products such as alcoholic drinks and tea and coffee, and the progress of food decay is delayed. It became a thing.
セラミックス層３を得るためには図３に示す工程のように、まずミルを用いて粉砕し、フルイ分けを行なう。粒子が１．０ｍｍ以上の場合は再度粉砕することが望ましい。フルイ分けしたものをさらに粉砕し、微粒子（特に４０μ以下が好ましい）を得、その微粒子とバインダー（接着剤）を合わせ混練し、その液体をスプレーで目的部分に噴射することでセラミックス層３を成形する。 In order to obtain the ceramic layer 3, first, it grind | pulverizes using a mill and performs a fluid division like the process shown in FIG. If the particles are 1.0 mm or more, it is desirable to grind again. The finely divided material is further pulverized to obtain fine particles (especially 40 μm or less), the fine particles and a binder (adhesive) are combined and kneaded, and the liquid is sprayed onto the target portion to form the ceramic layer 3. To do.
ここで、前記したセラミックスの粉体（微粒子）を試料として抗菌度を検査したところ、大腸菌、黄色ぶどう球菌に関して短時間で大きな効果が得られた。これはフィルム密着法により、対照区菌数−対数値で計算した（財団法人日本紡績検査協会近畿事業所による）。 Here, when the antibacterial degree was examined using the above-mentioned ceramic powder (fine particles) as a sample, a large effect was obtained in a short time with respect to Escherichia coli and Staphylococcus aureus. This was calculated by the film adhesion method using the number of control cells-logarithmic value (by the Japan Spinning Inspection Association Kinki Plant).
加えて、前記した試料で白癬菌につき検査をしたところ４８時間経過でその数は激減した。この場合、試験片としてポリエチレンフィルムを用い、溶液は０．００５％スルホこはく酸ジオクチルナトリウム溶液を用いた（財団法人日本食品分析センター微生物制御課による）。 In addition, when the above-mentioned samples were tested for ringworm, the number drastically decreased after 48 hours. In this case, a polyethylene film was used as a test piece, and a 0.005% dioctyl sodium sulfosuccinate solution was used (according to the Japan Food Analysis Center, Microorganism Control Section).
浴槽１の底側面及び床材２の表面にもセラミックス層３を形成することで、そのセラミックス層３からの遠赤外線放射により、浴槽１の保温性は高められ、隙間Ｓの空気層もその保温効果をさらに増強することとなる。 By forming the ceramic layer 3 on the bottom side surface of the bathtub 1 and the surface of the flooring 2, the thermal insulation of the bathtub 1 is enhanced by the far infrared radiation from the ceramic layer 3, and the air layer in the gap S is also kept warm. The effect will be further enhanced.
一方、図２として示す４は貯水槽を示し、この貯水槽４の内壁面にセラミックス層３を塗着形成してある。この場合は、セラミックス層３が保有する、殺菌、滅菌をも含めた意味での抗菌作用を応用したもので、比較的長時間に亘り収容されることとなる上水道水を衛生的に保持させることができることとなる。 On the other hand, reference numeral 4 shown in FIG. 2 denotes a water storage tank, and a ceramic layer 3 is formed on the inner wall surface of the water storage tank 4 by coating.
