According to the present invention, the surface of the stainless steel device can be coated in brass. In particular, since a stainless steel kitchenware such as a bowl can be safely coated with a brass color, it is possible to supply an inexpensive product that replaces a conventional expensive brass bowl. In addition, the coating of stainless steel provides a stainless steel product that eliminates the inherent odor of stainless steel and is easy to clean.
도 1은 본 발명에 따라 코팅한 놋쇠빛깔 코팅 스테인리스 그릇을 보여준다.1 shows a brass coated stainless steel bowl coated according to the present invention.
본 발명은 스테인리스 기기, 특히 그릇 등의 주방용기를 놋쇠빛깔로 코팅한다는데 특징이 있다. 이를 위해 본 발명은 물, 알코올 중 하나 이상에 의한 용제 40~60중량%, PTFE(Polytetra fluoro ethylene) 수분산제 10~30중량%, PTFE 파우더 5~20중량%, 마이카 1~10중량%, 아크릴 바인더 1~10중량%, 백색안료 1~10중량%, 금색안료 1~10중량%로 조성되는 놋쇠빛깔 코팅제 조성물을 제안한다. 여기에 세라믹 파우더 1~10중량%가 더 포함될 수 있다. 이들 재료의 함량범위는 코팅제로서의 코팅성과 사용성을 고려한 결과이다. The present invention is characterized by coating a stainless steel appliance, especially a kitchen vessel such as a bowl with a brass color. To this end, the present invention is a solvent 40 to 60% by weight of water or alcohol, 10 to 30% by weight PTFE (Polytetrafluorofluoroethylene) water dispersion, 5 to 20% by weight PTFE powder, 1 to 10% by weight mica, acrylic It is proposed a brass coating composition composed of 1 to 10% by weight of binder, 1 to 10% by weight of white pigment, and 1 to 10% by weight of gold pigment. 1 to 10% by weight of the ceramic powder may be further included. The content range of these materials is the result of considering the coatability and usability as a coating agent.
본 발명의 놋쇠빛깔 코팅제 조성물에서 용제와 PTFE 수분산제 및 PTFE 파우더은 일종의 테프론 코팅제가 된다. 백색안료와 금색안료는 놋쇠빛깔 발현을 위한 착색제가 되는데, 백색안료로는 산화아연, 산화타이타늄 등을 이용하면 적당하고, 금색안료로는 카드뮴옐로, 코발트옐로, 금박 등을 이용하면 적당하며, 놋쇠빛깔 발현을 위해 각각 1~10중량%에서 적절히 사용한다. 마이카는 천연 함수알루미늄실리케이트로 착색제, 충전제, 안티케이킹제 등으로 역할하고, 아크릴 바인더는 마이카와 백색안료 및 금색안료의 결합력을 부가하기 위한 결합재가 된다. 세라믹 파우더는 코팅제의 경도 강화를 위한 재료가 되는데, 실리카 타입이나 지르코늄 타입으로 평균 입자 크기가 5mm~10mm 이하인 것이 적당하다.In the brass coating composition of the present invention, the solvent, the PTFE water dispersion, and the PTFE powder become a kind of Teflon coating. White pigments and gold pigments are used as a colorant for the development of brass color. White pigments are suitable using zinc oxide and titanium oxide, and gold pigments are suitable using cadmium yellow, cobalt yellow, and gold leaf. Appropriately used at 1 to 10% by weight for the color expression respectively. Mica serves as a natural hydrous aluminum silicate as a colorant, filler, anti-caking agent, etc., the acrylic binder is a binder for adding the binding force of mica, white pigments and gold pigments. Ceramic powder is a material for strengthening the hardness of the coating, it is appropriate that the average particle size of 5mm ~ 10mm or less in the silica type or zirconium type.
이와 같은 놋쇠빛깔 코팅제 조성물은 용제에 PTFE 수분산제와 PTFE 파우더를 혼합 분산시키고 여기에 마이카, 아크릴 바인더, 안료, 세라믹 파우더를 혼합 교반하여 준비한다. 이렇게 준비된 놋쇠빛깔 코팅제 조성물은 스테인리스 기기 표면에 도포하여 350∼450℃에서 10~30분간 소성한 후 냉각하는 방식으로 코팅하면 되며, 여기서 코팅제의 도포는 고압분사방식이 적당하다.Such a brass coating composition is prepared by mixing and dispersing a PTFE water dispersant and a PTFE powder in a solvent and mixing and stirring a mica, an acrylic binder, a pigment, and a ceramic powder. The brass coating composition thus prepared may be coated on a surface of a stainless steel apparatus by firing at 350 to 450 ° C. for 10 to 30 minutes and then cooling the coating. The coating of the coating is preferably a high pressure spray method.
한편 놋쇠빛깔 코팅제 조성물로 코팅하기 전에, 스테인리스 기기를 400℃ 내외의 온도에서 30여 분간 소성하여 스테인리스 표면의 불순물을 제거하거나, 통상의 테프론 코팅용 프라이머로 도포 130~180℃에서 소성한 후 냉각하여 놋쇠빛깔 코팅제 조성물의 접착을 효과적으로 이루어지게 하는 것이 바람직하다. Meanwhile, before coating with the brass coating composition, the stainless steel machine is baked at a temperature of about 400 ° C. for about 30 minutes to remove impurities on the surface of the stainless steel, or after being baked at 130 to 180 ° C. with a conventional Teflon coating primer and cooled. It is desirable to make the adhesion of the brass coating composition effective.
또한 스테인리스 기기가 그릇과 같은 주방용기라면 외측 표면을 먼저 코팅한 후 내측 표면을 코팅하는 것을 바람직하다. 통상 그릇은 외측보다 내측 표면의 처리가 더 중요하게 여겨지는데, 내측 표면을 먼저 코팅하면 이후 외측 표면을 코팅하는 과정에서 코팅제가 내측 표면에 튈 수 있어 내측 표면이 매끄럽지 처리되지 않을 우려가 있기 때문이다.
In addition, if the stainless steel appliance is a kitchen vessel such as a bowl, it is preferable to coat the outer surface first and then the inner surface. Usually, the inner surface of the bowl is considered more important than the outer surface, because if the inner surface is coated first, the coating may float on the inner surface in the process of coating the outer surface, and the inner surface may not be smoothed. .
이하에서는 실시예에 의거하여 본 발명을 상세히 살펴본다. 다만, 하기의 실시예는 본 발명을 예시하기 위한 것일 뿐이며, 본 발명의 범위가 이로써 한정되는 것은 아니다.
