Description
본 발명은 각종 금속체 표면을 세라믹코팅하는 신규한 방법에 관한 것이다.The present invention relates to a novel method for ceramic coating various metal surfaces.
보다 상세하게 말하면, 본 발명은 금속산화물계 바인더와 무기충전재인 규산염으로 주로 구성되는 세라믹 코팅제를 이용하여 각종 금속체의 표면을 효율적으로 코팅하는 방법 및 그 제품에 관한 것이다.More specifically, the present invention relates to a method for efficiently coating a surface of various metal bodies using a ceramic coating agent mainly composed of a metal oxide binder and an inorganic filler silicate, and a product thereof.
금속으로된 제품은 파이프상, 판상, 봉상 등등 다양한 각종 형태로 제조되어 우리주변에서 널리 사용되고 있다.Metal products are manufactured in various forms such as pipes, plates, rods, etc. and are widely used around us.
이러한 금속제품은 외기에 노출되어 사용되기 때문에 습기등의 외부여건에 따라 쉽게 변색되고 부식되는 결점이 있다. 이 때문에 습기등의 외부조건이 조악한 환경에서 사용되어야 할 금속제품은 스테인레스 등의 특수금속 재료를 이용해야 했으나 이들 재료는 가격이 비쌀 뿐만 아니라 그 특징이 한정되어 있어 자연 그 용도가 제한되고 있다.Since these metal products are used after being exposed to the outside air, they are easily discolored and corroded according to external conditions such as moisture. For this reason, the metal products to be used in an environment with poor external conditions such as moisture had to use special metal materials such as stainless steel, but these materials are expensive and their characteristics are limited, so their use is limited.
한편 금속체 표면에 페인팅을 하거나 금속도금을 하거나 폴리에틸렌코팅을 수행하여 금속체의 내후성, 내식성 등을 향상시키는 방법이 또한 있으나 페인팅 방법의 경우는 시공은 손쉬우나 내구성이 약하고 금속체의 표면 효과가 미흡한 결점이 있고, 금속 도금법은 내구성은 양호하나 같은 금속계열이기 때문에 내식성, 내후성, 표면색상발현 효과등에 한계가 있고 비용이 또한 비싼 결점이 있으며, 폴리에틸렌코팅법은 부식 방지효과등은 좋으나 금속체표면이 미려하지 못하여 생활주변 장식용도로는 그 사용에 한계가 있다.On the other hand, there is also a method of improving the weather resistance and corrosion resistance of the metal body by painting, metal plating or polyethylene coating on the surface of the metal body. However, in the case of the painting method, the construction is easy but the durability is weak and the surface effect of the metal body is insufficient. It has defects, but the metal plating method has good durability, but because it is the same metal series, there are limitations in corrosion resistance, weather resistance, surface color expression effect, and the cost is also expensive. Polyethylene coating method has good corrosion protection effect, but metal surface is good. Because it is not beautiful, there is a limit to the use of decorative road around the life.
따라서 본 발명자는 종래의 금속체 표면처리 기술을 예의 검토하고 그 결점들을 혁신적으로 개선할 수 있는 가공방법을 오랫동안 예의 검토 연구해온 결과 본 발명을 완성하게 되었다.Therefore, the present inventors have completed the present invention as a result of a thorough investigation of a conventional metal surface treatment technology and a processing method that can innovatively improve the defects.
