Description

포토크로믹 물질이 구비된 자동차용 윈도우{car windows provided with photochromic material}Car windows provided with photochromic material}

본 발명은 햇빛의 세기에 따라 색깔을 띄는 포토크로믹(photochromic) 물질로 구비된 자동차용 윈도우에 관한 것이다.The present invention relates to a vehicle window provided with a photochromic material colored according to the intensity of sunlight.

일반적으로 유리는 SiO2를 주원료로 하여 제조되며, 투명하고 투광성이 우수하며 열전도율이 낮아 창유리, 판유리, 병유리 등과 같이 여러 가지 용도로 사용되고 있다. 유리는 일반적으로 원료준비 → 중량(Weighing) → 배치 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.Generally, glass is manufactured using SiO 2 as a main raw material, and is used for various purposes such as window glass, plate glass, and bottle glass because of its transparency, excellent light transmittance, and low thermal conductivity. Glass is generally manufactured through raw material preparation → weighing → batch mixing → molding → slow cooling → inspection and quality control → secondary process → inspection → packaging and so on. Special processes may be added, such as laminating, cladding, sand blasting, etching, metallizing, and the like.

또한, 유리는 배치(batch)에 다른 착색제를 첨가시켜 여러 가지 다른 색깔의 유리를 만들 수 있다. 예를 들어, 대부분의 금속산화물은 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.In addition, the glass can be made of glass of different colors by adding different colorants to the batch. 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. 즉, 차량에 사용되는 윈도우는 투명체로서, 햇빛의 차단을 위해, 선팅지를 붙여 사용한다. 그러나, 이러한 선팅지는 비오는 날이나 터널 내에서 차량의 실내를 어두운 상태로 유지하는, 즉 햇빛 차단을 원하는 시기에 할 수 없다는 문제가 있다.However, conventional glass is endowed with only the intrinsic properties and effects of the glass and no other beneficial properties. In other words, the window used in the vehicle is a transparent body, which is used by pasting paper to block sunlight. However, such sunting paper has a problem in that it is impossible to keep the interior of the vehicle in a dark state on a rainy day or in a tunnel, that is, when it is desired to block sunlight.

한편, 썬팅이 되어 있지 않은 자동차 유리창에 있어서, 특히 여름철의 경우 유리창을 통해 들어오는 햇빛에 의하여 차내의 온도가 쉽게 상승하기 때문에 운전중에는 냉방기를 자주 사용하게 되고, 또 장시간 주차시에는 차내 온도가 너무 높아져 있어 탑승자가 즉시 차안으로 탑승하지 못하는 문제점이 있었다.On the other hand, in unattended car windshields, especially in summer, the temperature inside the car easily rises due to the sunlight coming through the windshield, so the air conditioner is frequently used during driving, and the temperature inside the car becomes too high during long parking. There was a problem that the occupants could not board in the car immediately.

본 발명은 전술한 문제점을 해결하기 위해 안출된 것으로서, 햇빛의 세기에 따라 색깔을 자동으로 조정하여 원하는 시기에 햇빛을 차단할 수 있는 포토크로믹 물질을 이용한 자동차용 윈도우를 제공하는 데 그 목적이 있다.SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and an object thereof is to provide a window for a vehicle using a photochromic material that can block sunlight at a desired time by automatically adjusting the color according to the intensity of sunlight. .

That is, the process of manufacturing the glass to which the photochromic material is added includes a raw material preparation step of preparing a glass raw material powder and a mixing of the photochromic material (2) which is actively changed in color by light to the glass raw material. Process, a melting process in which a glass raw material mixed with the photochromic material is put into a furnace and heated to a high temperature, and pressing / molding pressurized at a high pressure to make the molten mixture material into a predetermined shape. The glass 1 according to the present invention is manufactured through a process and a process of cutting and inspecting the pressurized / molded glass to a desired dimension as described above. Here, the process of manufacturing the glass is the same as the method of manufacturing a conventional glass, in the present invention, instead of the general method of producing a colored glass by adding a colorant to the glass raw material, in the present invention a photochromic material It is characterized by producing a glass having a variety of color variations by the addition.

또한, 본 발명의 다른 실시예로서, 도 3과 같이 상기 포토크로믹 물질을 유리원료에 첨가시키지 않고 유리판에 포토크로믹 소재로 된 코팅막(3)을 형성할 수도 있을 것이다.In addition, as another embodiment of the present invention, as shown in FIG. 3, the coating film 3 of photochromic material may be formed on the glass plate without adding the photochromic material to the glass raw material.

여기서, 상기 크로믹 물질이란 외부의 자극에 의하여 능동적으로 색감을 띠는 물질을 말하며, 포토크로미즘은 빛의 세기에 따라 색이 가역적으로 변화하는 현상을 말한다. 즉, 상기 포토크로믹 물질은 햇빛에 의하여 가역적으로 색변화를 하게 되고, 그 빛의 세기에 따라 다양한 색감을 나타낼 수 있으며, 빛이 없는 어두운 곳에 방치하게 되면 열적으로 원상태로 되돌아가 다시 무색을 띄게 되는 것이다.Here, the chromic material refers to a material that is actively colored by an external stimulus, and photochromism refers to a phenomenon in which color is reversibly changed according to light intensity. That is, the photochromic material is reversibly changed color by sunlight, and may exhibit various colors depending on the intensity of light, and when left in a dark place without light, the photochromic material is thermally returned to its original state and becomes colorless again. Will be.

상기 포토크로믹 물질은 특별히 제한되지 않으며, 무기화합물의 구체적인 예로써 할로겐화은(silver halide), Hg3S2I2,ZnS 등이 있고, 유기화합물의 구체적인 예로서 각종 히드라존(hydrazone) 화합물, 오사존(osazone), 풀기드(fulgide), 스틸벤(stilbene), 살리실 알데히드(salicylaldehyde) 등이 있다.The photochromic material is not particularly limited, and specific examples of the inorganic compounds include silver halide, Hg 3 S 2 I 2, and ZnS.
