포토크로미즘 원리를 이용한 자연친화형 유리{A natural glass using photochromism principle}A natural glass using photochromism principle

본 발명은 포토크로미즘(photochromism) 원리를 이용한 자연친화형 유리에 관한 것으로, 보다 상세하게는 유리의 가공시 유리의 주성분에 빛의 세기에 의해 다양한 색깔을 띄는 포토크로믹 소재를 첨가하여 압출 성형한 유리를 제조하는 포토크로미즘 원리를 이용한 자연친화형 유리에 관한 것이다.The present invention relates to a nature-friendly glass using a photochromism principle, more specifically, extrusion processing by adding a photochromic material having a variety of colors by the intensity of light to the main component of the glass when processing the glass It relates to a nature-friendly glass using the photochromism principle to produce a glass.

일반적으로 유리는 SiO2를 주원료로 하여 제조되며, 투명하고 투광성이 우수하며 열전도율이 낮아 창유리, 판유리, 병유리 등과 같은 여러 가지 용도로 사용되고 있다.In general, glass is manufactured using SiO 2 as a main raw material, and is used for various uses such as window glass, plate glass, and bottle glass because of its transparency, excellent light transmittance, and low thermal conductivity.

상기 유리의 구조는 대부분의 금속처럼 잘 알려져 있지 않으며, 독특한상태를 가져 유리상이라고 칭하여지고, '결정화하지 않고 딱딱한 상태로 냉각되는 용융산물'이라고 정의된다.The structure of the glass is not as well known as most metals, it has a unique state and is called a glass phase, and is defined as a 'melt product that is cooled to a hard state without crystallization'.

한편, 유리는 일반적으로 원료준비 → 중량(Weighing) → 뱃치 믹싱(Batch Mixing) → 성형 → 서냉 → 검사와 품질관리→ 2차공정 → 검사 → 포장 등의 공정을 거쳐 제조되고, 용도에 따라 서냉, 강화, 라미네이트, 클래딩(Cladding), 샌드블라스팅(Sand Blasting), 에칭(Etching), 메탈라이징(Metalling) 등과 같은 특별한 공정들이 부가될 수 도 있다.Meanwhile, glass is generally manufactured through raw material preparation → weighing → batch mixing → molding → slow cooling → inspection and quality control → secondary process → inspection → packaging. Special processes may be added, such as strengthening, laminating, cladding, sand blasting, etching, metalling, and the like.

또한, 유리는 뱃치(batch)에 다른 착색제를 첨가시켜 여러 가지 다른 색깔의 유리를 만들 수 있다.In addition, the glass can be made of glass of different colors by adding different colorants to the batch.

예를들어, 대부분의금속산화물은 유리에 용해되어 착색된 투명유리를 형성하며, 유황과 셀레늄 성분은 유리에서 콜로이드 상태로 나타나 유리에 투명성을 부여하고, 오팔 유리(opal glass)는 유리에 미세한 불소화합물의 결정질 함유물을 갖게 함으로 형성된다.For example, most metal oxides dissolve in glass to form colored transparent glass, and sulfur and selenium components appear colloidally in the glass, giving transparency to the glass, and opal glass gives fine fluorine to the glass. It is formed by having a crystalline content of the compound.

그러나, 종래의 유리는 유리의 고유 특성 및 효과만이 부여될 뿐 다른 유익한 특성이 부여되지 않는다.However, conventional glass is endowed with only the intrinsic properties and effects of the glass and no other beneficial properties.

또한, 자외선의 차단 및 빛을 선택적으로 흡수하기 위해 다양한 색깔을 띈 착색제를 첨가시키거나, 코팅막으로 사용하고 있지만 기대에 미치지 못하고 있다.In addition, various colors are added to the blocking of ultraviolet rays and selectively absorbing light, or used as a coating film, but it does not meet expectations.

그리고, 유리성분으로 제조된 자동차 유리, 안경 등도 외부의 강한 빛을 그대로 통과시켜 시야를 흐리게 하는 문제점이 있었다.In addition, automotive glass, glasses and the like made of a glass component had a problem of blurring the field of view by passing external strong light as it is.
