Abstract
Description
본 발명은 음이온 및 원적외선을 방출하는 주방용기용 세라믹 코팅조성물에 관한 것으로, 더욱 상세하게는 기존에 각종 주방용기(예를 들어 프라이팬, 밥솥, 냄비, 구이판 등)의 표면에 코팅되는 테프론 코팅조성물의 테프론 수지 성분의 일부를 내구성이 우수한 세라믹 성분으로 대체하고, 여기에 카올린과 몬몰린라이트를 주성분으로 하며, 미생물로 활성화된 점토를 첨가시켜 원적외선과 음이온의 방사 및 발생을 통해 항균, 살균 및 탈취 효과를 증진시킨 음이온 및 원적외선을 방출하는 주방용기용 세라믹 코팅조성물에 관한 것이다.The present invention relates to a ceramic coating composition for discharging anion and far infrared rays, and more particularly, to a Teflon coating composition coated on a surface of various kitchen containers (for example, a frying pan, a rice cooker, a pot, a roasting plate, etc.). Some of the resin components are replaced with durable ceramic components, and the main components are kaolin and montolinite, and microorganism-activated clay is added to prevent the anti-microbial, sterilization and deodorizing effect through the radiation and generation of far infrared rays and anions. The present invention relates to a ceramic coating composition for kitchen vessels that emits enhanced anions and far infrared rays.
일반적으로 가정이나 음식점, 야외 등에서 사용되는 냄비, 식기, 프라이팬, 전기밥솥 등의 가열 조리기는 음식물이 조리되는 과정에서 용기의 표면에 가급적 달라붙지 않도록 하기 위하여 금속으로 된 용기의 표면에 불소 수지(상품명: 테프론(Teflon))를 코팅하여 사용되고 있다.In general, heating cookers such as pots, utensils, pans, and rice cookers used in homes, restaurants, and the outdoors are used to prevent fluorine resin (metal) from the surface of a metal container in order to prevent food from sticking to the surface of the container. : Teflon coating is used.
이러한 테프론 수지는 PTFE(Poly Tetra Fluoro Ethylene), FEP(Fluorinated Ethylene Propylene copolymer), 및 PFA(Per Fluoro Alkoxy)와 같이 3가지 형태를 기본으로 하는 물질로서 불소 탄화물계 수지의 관용어이다.The Teflon resin is a idiom for fluoride carbide-based resins as a material based on three forms, such as PTFE (Poly Tetra Fluoro Ethylene), Fluorinated Ethylene Propylene copolymer (FEP), and Per Fluoro Alkoxy (PFA).
상기 PTFE(Poly Tetra Fluoro Ethylene) 코팅은 초도/상도(One or Two-Coat) 방식이다. 기본물질로 불소수지 중에서 사용온도가 가장 높으며 (290℃), 마찰계수가 극히 작고, 내마모성 및 내화학성, 비점착성이 우수, 다공성 필름형성, PTFE 코팅제는 주로 수성제품이다.The PTFE (Poly Tetra Fluoro Ethylene) coating is a one- or two-coat method. Among the fluorine resins, it has the highest use temperature (290 ℃), extremely low coefficient of friction, excellent abrasion resistance, chemical resistance, and non-tackiness, porous film formation, and PTFE coating agent.
상기 FEP(Fluorinated Ethylene Propylene copolymer) 코팅은 소결과정에서 유동성을 지닌 물질로 변하여 무공질의 필름을 형성하며 이러한 FEP 코팅은 우수한 내화학성, 내부식성, 매우 낮은 마찰계수, 뛰어난 비점착성을 갖는다. 최고 사용 온도는 205℃이며, 수성제품 또는 분말 형태로 공급된다.The FEP (Fluorinated Ethylene Propylene copolymer) coating is transformed into a material having fluidity during sintering to form a nonporous film. The FEP coating has excellent chemical resistance, corrosion resistance, very low coefficient of friction, and excellent non-adhesiveness. The maximum service temperature is 205 ° C and is supplied in the form of an aqueous product or powder.
상기 PFA(Per Fluoro Alkoxy) 코팅은 FEP와 같이 무공질의 필름을 형성한다. PFA의 또 다른 장점은 연속사용 한계온도가 높고(260℃), 필름 두께를 1000㎛이상 올릴 수 있으며, PTFE나 FEP보다 우수한 내구성을 가진다. 이러한 특성들로 해서 PFA는 사용 용도가 매우 광범위하며 특히 내화학성이 필요한 부분에 많이 사용되며 PFA 제품은 수성 또는 분말 형태로 공급된다.The PFA (Per Fluoro Alkoxy) coating forms a porous film like FEP. Another advantage of PFA is that the limit of continuous use temperature is high (260 ℃), the film thickness can be increased to over 1000㎛, and it has better durability than PTFE or FEP. Due to these properties, PFA has a wide range of uses, especially in areas requiring chemical resistance, and PFA products are supplied in aqueous or powder form.
상기 테프론 코팅은 거의 모든 물질이 잘 달라붙지 않는 비점착성, 물기나 기름이 잘 묻지 않는 비유성, 높은 온도(260℃)에서도 분해가 일어나지 않는 내열성, 낮은 온도에서도 물리적 특성이 변하지 않는 저온도 내구력, 주변의 화학적 환경에도 거의 영향을 받지 않는 등의 특성을 가지고 있어 가열조리용기 이외에도 냉 장고의 알루미늄 아이스 트레이(Ice-Tray), IH-Jar(Inducter heating-jar), GOR 트레이(Tray) 등 각종 금형을 비롯한 기계류 및 전자부품 등에 널리 적용되고 있다.The Teflon coating has a non-tackiness that almost all materials do not stick well, a non-oiliness that does not adhere to moisture or oil, heat resistance that does not occur at high temperatures (260 ° C.), and low temperature durability that does not change physical properties even at low temperatures. It is hardly influenced by the surrounding chemical environment, and in addition to heating cooking containers, various molds such as aluminum ice tray (Ice-Tray), IH-Jar (Inducter heating-jar) and GOR tray (Tray) It is widely applied to machinery and electronic parts, such as.
이러한 테프론 수지를 조리용기에 코팅하는 기존의 방법은 금속의 소재를 드로잉(Drawing), 트리밍(Trimming)하여 제품형태로 제작하여 세척하고, 250℃에서 350℃ 사이에서 30∼40분간 에이징(소둔) 처리한 후 약 60메쉬(Mesh)의 샌드(Sand)를 이용하여 5㎏/㎠의 압력으로 샌딩(Sand blast)을 하여 3∼5㎛의 표면조도가 유지되도록 한다. 그런 다음, 표면에 프리머(Primer) 처리를 하고, 베이킹처리한 후, 분사방법으로 테프론 코팅을 한 다음 320℃∼400℃의 온도로 30∼40분간 베이킹 처리를 하여 코팅작업을 완료한다.Conventional method for coating such a Teflon resin in a cooking vessel is manufactured by drawing and trimming metal material into a product form and washing it, and aging (annealing) between 250 ° C and 350 ° C for 30 to 40 minutes. After the treatment, the sand is sanded at a pressure of 5 kg / cm 2 using sand of about 60 mesh to maintain surface roughness of 3 to 5 μm. Then, the surface of the primer (Primer) treatment, baking, Teflon coating by the spray method, and then baked for 30 to 40 minutes at a temperature of 320 ℃ to 400 ℃ to complete the coating work.
그러나, 이러한 종래의 테프론 코팅방법에 의한 제품은 단순히 테프론이 갖고 있는 특성들만을 갖고 있을 뿐 항균, 탈취 등의 특성을 갖추지 못하였다. 즉, 상기 테프론 코팅된 제품은 주로 주방용품으로 사용되는 것으로서, 습기에 의하여 각종 세균이 번식되는 경우가 많아 비위생적이며, 이에 대한 각별한 주의가 필요하였다.However, the conventional Teflon coating method has only the characteristics of Teflon, but it does not have characteristics such as antibacterial and deodorization. That is, the Teflon-coated products are mainly used as kitchen utensils, and many bacteria are multiplied by moisture, which is unsanitary, and special care has to be taken.
이에 아래의 특허문헌 1 및 특허문헌 2에서는 각각 공지의 테프론 코팅방법에 있어서, 5.5∼6.5미크론의 입자로된 토르마린 분말을 불소수지에 1∼15% 혼합하여 구성된 토르마린이 함유된 테프론 코팅방법과 주방용기의 내면에 분말의 토르말린 입자가 포함된 불소수지 코팅막이 형성된 주방용품을 개시하고 있다.Accordingly, Patent Document 1 and Patent Document 2 below disclose a known Teflon coating method, a tourmaline-containing Teflon coating method composed of 1 to 15% mixed tourmaline powder of 5.5 to 6.5 micron particles with a fluorine resin and a kitchen. Disclosed is a kitchen utensil in which a fluororesin coating film containing powder tourmaline particles is formed on an inner surface of a container.
또한, 특허문헌 3에서는 주방용기의 외면에 열풍건조되되, 장석 60%, 규석 10%, 점토 7%, 물 20%, 붕사 3%로 혼합된 혼합물이 코팅되어 형성된 법랑과, 상기 법랑의 내면에 열풍건조되되, 용사처리 및 1, 2, 3차로 다중코팅된 테프론 코팅을 포함하는 외면 법랑 및 내면 테프론 코팅된 주방용기를 개시하고 있고, 한국 특허출원 제87-1451호에서는 플루오로카본 중합체와 파장이 2.5-1000㎛인 원적외선 방사물질로 제도된 화인세라믹 프릿(frit)를 1 : 1.5 ∼ 3 : 1의 비율로 혼합시킨 원적외선 방사물질을 포함한 피복용 중합체 조성물을 개시하고 있다.In addition, Patent Document 3 is hot air dried on the outer surface of the kitchen container, enamel formed by coating a mixture mixed with 60% feldspar, 10% silica, 7% clay, 20% water, 3% borax, and on the inner surface of the enamel Exterior air enamel and interior Teflon-coated kitchen containers comprising hot-air-dried, thermally treated and 1, 2, and 3 multi-coated Teflon coatings are disclosed, and Korean Patent Application No. 87-1451 discloses fluorocarbon polymers and wavelengths. Disclosed is a polymer composition for coating comprising a far-infrared radiation substance in which a fine ceramic frit drawn with a 2.5-1000 µm far-infrared radiation substance is mixed at a ratio of 1: 1.5-3: 1.
아울러, 특허문헌 4에서는 카올린과 몬몰린라이트를 50중량% 이상 포함하며, 상기 카올린과 몬몰린라이트의 비율이 6∼8 : 2∼4인 점토를 약 40℃에서 24∼48시간 배양한 다음, 80∼90℃에서 건조시키고, 200∼300메쉬로 분쇄시킨 활성 점토 분말을 전체 테프론 코팅조성물에 대하여 3∼10중량%로 함유하는 음이온 및 원적외선을 방출하는 주방용기용 테프론 코팅조성물을 개시하고 있다.In addition, Patent Literature 4 includes 50% by weight or more of kaolin and montolin light, and the incubation of the clay with a ratio of kaolin and montolin light 6-8: 2-4 at about 40 ° C for 24 to 48 hours, Disclosed is a teflon coating composition for discharging anions and far infrared rays containing 3 to 10% by weight of active clay powder dried at 80 to 90 ° C. and ground to 200 to 300 mesh based on the total thickness of the Teflon coating composition.
그러나, 이러한 종래의 테프론 코팅에 첨가된 토르말린 또는 세라믹 물질들은 광물질이므로 원적외선 방사량 및 음이온 방출량이 적을 뿐만 아니라 테프론 코팅 조성물과의 혼화성이 떨어져 테프론 코팅후의 물리적, 기계적 특성이 떨어지는 단점이 있다. 아울러, 기존의 테프론 코팅 조성물은 테프론의 많은 장점에도 불구하고, 테프론의 내구성이 떨어져 금속 팬의 바닥면으로부터 쉽게 벗겨지며, 테프론 성분 자체가 인체에 유해한 단점이 있다.However, since the tourmaline or ceramic materials added to the conventional Teflon coating is a mineral material, not only the amount of far-infrared radiation and anion emission are low, but also the compatibility with the Teflon coating composition is low, so that the physical and mechanical properties after the Teflon coating are inferior. In addition, the conventional Teflon coating composition, despite the many advantages of Teflon, the durability of the Teflon is easily peeled off from the bottom surface of the metal pan, the Teflon component itself has a disadvantage that is harmful to the human body.

The cell function is activated, the growth is promoted, the water molecules are activated, as well as the aging effect can be obtained. Therefore, a great effect is expected for allergic and atopic skin owners. In addition, the antimicrobial, sterilizing and deodorizing effect of far infrared rays and anions not only enhances the taste of the food, but also eliminates the peculiar smell of the food. It penetrates into the water, and the food itself ripens from the inside, and can decompose harmful substances to the human body and save energy.
또, 조리 후 장시간이 지나도 기름이 응고되지 않으므로 주방용기의 세척을 간편하게 실시할 수 있고, 집안에 냄새가 나는 것을 최소화할 수 있어 별도의 방향 또는 탈취제의 사용이 필요 없게 된다.In addition, the oil does not coagulate even after a long time after cooking can be easily washed in the kitchen container, it is possible to minimize the smell of the house, there is no need to use a separate aroma or deodorant.
