Abstract

본 발명은 무기질 소재를 알루미늄 표면에 도포 융착시켜 줌으로서, 내열성, 내충격성, 내마모성, 내오염성, 내산성 및 내부식성 등이 매우 우수한 알루미늄 법랑을 제조하는 방법에 관한 것이다.The present invention relates to a method for producing an aluminum enamel having excellent heat resistance, impact resistance, abrasion resistance, fouling resistance, acid resistance and corrosion resistance by applying and welding an inorganic material to an aluminum surface.

종래의 철 법랑은 중량이 대단히 커서, 취급시 많은 노동력과 세심한 주의가 필요할 뿐만 아니라,일단 고열로 소성되어진 다음에는 절곡이나 절단 등의 후가공 처리가 거의 불가능하며, 또한 작은 충격이나 급격한 온도 변화에 의하여 도포된 법랑에 균열이 발생되어, 그 틈 사이로 철판의 녹물이 새어 나오고 급속한 부식이 진전되어 법랑이 쉽게 박리되거나 파손되는 등의 많은 불편한 점이 있었다.Conventional iron enamel is very large, which requires a lot of labor and careful attention in handling, and once it is fired at high temperature, it is almost impossible to process after bending or cutting, and also due to a small impact or rapid temperature change. There were many inconveniences such as cracks in the coated enamel, leakage of iron plate leaked out between the gaps, rapid corrosion progressing, and the enamel was easily peeled off or broken.

그래서, 본 알루미늄 법랑은 종래의 이러한 불편한 점을 해소하기 위하여, 유리질 실리카를 주성분으로 하는 무기질 소재를 알루미늄 표면에 직접 도포 융착시켜 줌으로서, 밀착성이 매우 양호해져 비교적 강한 충격이나 급격한 절곡에도 법랑이 박리되지 않으며, 특히 500℃의 고온에서 소성시켜 만들었으므로 상온에서는 반영구적으로 색상변화가 일어나지 않으며, 또한 법랑 표면에 견고한 유리질이 형성되어, 내마모성, 내오염성, 내산성 및 내부식성 등이 매우 우수한 알루미늄 법랑을 제조할 수 있는 방법에 관한 것이다.Therefore, in order to solve such inconveniences in the related art, this aluminum enamel is directly coated and bonded with an inorganic material mainly composed of glassy silica on the surface of aluminum, so that the adhesion is very good, and the enamel is peeled off even with a relatively strong impact or sudden bending. In particular, since it is made by calcining at high temperature of 500 ℃, color change does not occur semi-permanently at room temperature, and solid glass is formed on the surface of enamel, thus producing aluminum enamel having excellent abrasion resistance, pollution resistance, acid resistance and corrosion resistance. It's about how you can do it.
