Description
본 발명은 건재용으로 적합한 적색결정화유리의 제조방법에 관한 것으로서, 더욱 상세하게는 특정조성의 유리원료혼합물에 염화주석(SnCl2)과 탄소(C) 및 산화구리를 첨가한 후 용융하여 물급냉으로 소체화시키고, 그 소체를 내화물 모울드에 집적시킨 다음 재가열시킴으로써, 유리중에 천연대리석모양의 결정을 생성시키는 과정에서 금속콜로이드에 의해 적색으로 착색되도록 하는 적색 결정화 유리의 제조방법에 관한 것이다.The present invention relates to a method for manufacturing red crystallized glass suitable for building materials, and more particularly, to adding glass of a specific raw glass mixture to tin chloride (SnCl 2 ), carbon (C) and copper oxide, followed by melting and quenching. The present invention relates to a method for producing red crystallized glass which is colored by red metal by colloid in the process of forming a natural marble crystal in glass by integrating the body into a refractory mold and then reheating the body.
일반적으로 건축물의 내, 외장등의 건재로서 천연석 모양의 포스터라이트(Forsterite)계 결정화유리, 휘석계(輝石系) 결정화유리, 울라스토나이트(Wollastonite)계 결정화 유리등의 제조방법이 제안되고 있다.In general, manufacturing methods such as natural stone-shaped Forsterite-based crystallized glass, whisker-based crystallized glass, and wollastonite-based crystallized glass have been proposed as building materials for interior and exterior of buildings.
그중에서는 울라스토나이트계 결정화유리의 착색방법에는 2가지가 있다.Among them, there are two kinds of coloring methods for the urastonite-based crystallized glass.
첫째는, 원료배치(batch)상에 착색제를 투입하여 용융한 것을 소체화하고 열처리시켜서 제조하는 것이고, 둘째는, 일단 흰소체를 제조한 후에 착색제를 투입하여 열처리함으로써 특유의 고유색을 만들어내는 방법이 있다.First, the colorant is added to a batch of material to melt the melted material and heat-treat it. Secondly, after the white body is manufactured, the colorant is added and heat-treated to produce a unique color. have.
이러한 방법에 있어서 결정화 유리에서의 착색은 유색이온에 의해 착색이 되는 것인데, 결정화 유리에 착색시키는 이온은 2가지 이상의 서로다른 원자가를 갖는 이온이 대부분이고, 그 원가가의 다름에 의해 서로 다른색으로 착색되는 경우가 있다.In this method, the coloration in the crystallized glass is colored by colored ions. Most of the ions to be colored in the crystallized glass are ions having two or more different valences, and the color is different depending on the cost. It may be colored.
이는 유리를 용융시킬때 주위의 분위기가 산화성 분위기인가 환원성 분위기인가에 크게 영향을 받는 것이고, 또한 같은 원자가라도 그 유색이온을 둘러싸고 있는 산소이온의 수에 의해서도 착색이 달라지는 경우가 발생되며, 기초유리의 조성차이에 의해서도 착색이 달라지는 등 제약조건이 많기 때문에, 특히 적색 결정화 유리를 제조하기는 매우 어려운 것으로 알려져 있다.This is because when the glass is melted, the surrounding atmosphere is greatly influenced by the oxidizing atmosphere or the reducing atmosphere, and even when the same valence is changed depending on the number of oxygen ions surrounding the colored ions, the color of the base glass is changed. It is known that it is very difficult to manufacture red crystallized glass especially because there are many constraint conditions, such as a coloring which changes also by composition difference.
최근에 들어서는 울라스토나이트 결정화유리의 제조시 흰소체에 착색제를 투입하여 자색을 띠게하는 방법이 개발되어 있으나, 이 방법에 있어서도 건재용 결정화유리에 있어서의 중요한 문제라 할 수 있는 천연석 모양의 자연스러운 패턴(pattern)이 나타나지 않게 되고, 표면에 깊은 질감을 나타내는 막이 형성되지 않을 뿐아니라, 전반적으로 조잡한 느낌을 주기때문에 상품가치가 현저히 떨어지는 문제는 여전히 남아있었다.Recently, a method of making purple color by adding a colorant to a white body during the manufacture of urastonite crystallized glass has been developed, but also in this method, a natural pattern of natural stone shape, which is an important problem in crystallized glass for building materials There was still a problem of not having a pattern, not forming a deep textured film on the surface, and giving a rough feeling overall, so that the value of the product was significantly reduced.
따라서, 본 발명은 유색이온에 의한 착색 결정화 유리의 제조시 상기와 같은 여러 난점을 해소하고 적색 결정화유리를 제조하기 위해, 유리 원료 혼합물중에 염화주석(SnCl2), 탄소(C) 및 산화구리를 일정량 첨가한 유리를 성형하여 소정의 재열처리를 시행함으로서, 유리중에 균일하게 분산되어 있는 미세한 금속콜로이드에 의해 적색으로 착색되도록 하는 개선된 적색 결정화 유리 제조방법을 제공하는데 그 목적이 있다.Therefore, the present invention solves the above-mentioned difficulties in the production of colored crystallized glass by colored ions and to prepare tin crystal (SnCl 2 ), carbon (C) and copper oxide in the glass raw material mixture in order to produce red crystallized glass. It is an object of the present invention to provide an improved method for producing red crystallized glass in which a predetermined amount of glass is formed and subjected to a predetermined reheat treatment, thereby allowing the glass to be colored red by fine metal colloids uniformly dispersed in the glass.
이하, 본 발명을 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail.
본 발명은 결정화 유리를 제조함에 있어서, SiO245∼70중량%, Al2O35∼10중량%, CaO 10∼20중량%, ZnO 5∼12중량%, B2O31∼5중량%, Na2O 0.5∼5중량%, K2O 0.5∼5중량% 및 Sb2O30.1∼3중량%의 조성을 갖는 유리원료혼합물에다 염화주석(SnCl2), 탄소(C) 및 산화구리를 첨가시키고 전기로에서 용융시켜서 소체화시킨후, 전기로에서 열처리시키고 냉각시켜서 금속콜로이드에 의해 적색으로 착색되도록 하는 것을 특징으로 하는 적색 결정화 유리에 제조방법이다.In manufacturing the crystallized glass, the present invention, 45 to 70% by weight of SiO 2 , 5 to 10% by weight of Al 2 O 3, 10 to 20% by weight of CaO, 5 to 12% by weight of ZnO, 1 to 5% by weight of B 2 O 3 Tin chloride (SnCl 2 ), carbon (C) and copper oxide in a glass raw material mixture having a composition of%, Na 2 O 0.5-5 wt%, K 2 O 0.5-5 wt% and Sb 2 O 3 0.1-3 wt% The method for producing a red crystallized glass, which is added to and melted in an electric furnace to be elementary, and then heat treated and cooled in an electric furnace to be colored red by a metal colloid.
이와같은 본 발명을 더욱 상세히 설명하면 다음과 같다.Referring to the present invention in more detail as follows.
본 발명은 상기와 같은 조성을 갖는 유리원료 혼합물에다 염화주석(SnCl2)와 탄소(C) 및 Cu2O 또는 CuO와 같은 산화구리를 첨가시키되 그 유리원료 혼합물에 대해 각각 염화주석 0.01∼4.0중량% 바람직하기로는 0.1∼2.5중량%, 탄소 0.01∼3.0중량% 바람직하기로는 1.5∼2.5중량%, 그리고 산화구리 0.01∼4.0중량% 바람직하기로는 0.1∼2.5중량%로 첨가 혼합시키고, 이를 전기로에서 용융시킨후 특정온도에서 물급냉(Water-quenching)으로 소체화시키므로서 1∼20㎜크기의 소체를 얻고, 이를 내화물모울드(mold)에 넣어서 전기로에서 열처리시키므로서 적색으로 착색된 결정화 유리가 제조되는 것이다.In the present invention, tin chloride (SnCl 2 ) and carbon oxide (C) and copper oxide such as Cu 2 O or CuO are added to a glass raw material mixture having the composition as described above, and 0.01 to 4.0 wt% of tin chloride is added to the glass raw material mixture, respectively. Preferably, 0.1 to 2.5% by weight, carbon to 0.01 to 3.0% by weight, preferably 1.5 to 2.5% by weight, and 0.01 to 4.0% by weight of copper oxide, preferably 0.1 to 2.5% by weight, and the mixture is melted in an electric furnace. After the body at a specific temperature by water-quenching (Water-quenching) to obtain a body size of 1 ~ 20㎜, and put it in a refractory mold (heat) in the electric furnace to produce a crystallized glass colored in red.
이러한, 본 발명에 따르면 상기와 같은 방법에서 유리내부에 천연석 모양의 결정인 울라스토나이트가 석출되면서 성장됨은 물론, 열처리 과정에서 산화구리가 탄소와 염화주석에 의한 열적 환원을 받아서 금속원자로 되기때문에, 그 금속콜로이드에 의해 적색으로 착색된 결정화유리를 제조할 수 있게 된다.According to the present invention, as the above-described method is grown by precipitation of urastonite, which is a natural stone crystal in the glass, as well as copper oxide undergoes thermal reduction by carbon and tin chloride in the heat treatment process, so as to become a metal atom, It becomes possible to manufacture crystallized glass colored in red by the metal colloid.
다시말하면, 상기 방법에서 열처리 과정중 구리(Cu)가 Cu+상태로 유리중에 균질하게 분산되어 있다가 주석(Sn)과 탄소(C)에 의한 열적 환원을 받아 금속원자(Cu°)로 되는데, 이때의 반응식은 다음과 같이 표시될 수 있다.In other words, during the heat treatment process, copper (Cu) is uniformly dispersed in the glass in a Cu + state, and is thermally reduced by tin (Sn) and carbon (C) to form a metal atom (Cu °). The reaction scheme at this time may be expressed as follows.
2Cu++Sn2→ 2Cu°+Sn4 2Cu + + Sn 2 → 2Cu ° + Sn 4
이때 형성된 구리원자(Cu°)가 어느 농도 이상이 되면, 서로 응집하여 미세한 콜로이드 입자로 석출되므로서 적색으로 착색된 결정화 유리를 형성하게 되는 것이다.At this time, when the formed copper atom (Cu °) is more than a certain concentration, it is agglomerated with each other to precipitate as fine colloidal particles to form a crystallized glass colored in red.
이와같은 본 발명에서, 상기 전기로에서의 용융열처리는 1400∼1600℃까지 30∼600℃/hr로 승온시키면서 0.5∼4시간동안 유지시키고나서, 다시 약 1400℃에서 0.5∼2시간동안 유지시키는 방법으로 처리하며, 이를 물급냉시키서 소체를 제조한다.In the present invention as described above, the heat treatment of the melting in the electric furnace is maintained at 0.5 to 4 hours while raising the temperature to 30 to 600 ℃ / hr to 1400 to 1600 ℃, and then maintained at about 1400 ℃ for 0.5 to 2 hours It is treated and water-quenched to produce a body.
또한, 이렇게 제조된 소체를 내화모울드에 넣고 열처리로에서 열처리시키는데, 이때의 열처리는 전기로에서 30∼300℃/hr의 승온속도로 900∼1200℃까지 승온시켜서 0.5∼5시간 유지시키는 방법으로 열처리시키고, 그후 노냉시킨다.In addition, the thus prepared body is placed in a refractory mold and heat-treated in a heat treatment furnace, wherein the heat treatment is heat-treated in an electric furnace by raising the temperature to 900-1200 ° C. at a heating rate of 30-300 ° C./hr and maintaining it for 0.5 to 5 hours. After that, cool it.
이와같이 결정화된 본 발명에 따른 적색결정화 유리는 연마처리하여 최종제품을 제조하게 된다.The red crystallized glass according to the present invention crystallized as described above is polished to produce a final product.
상술한 바와같이 본 발명의 적색 결정화유리 제조방법에 의해 제조된 결정화 유리는 우수한 표면 패턴과 천연석 모양의 막을 형성함은 물론, 유리중에 분산되어 있는 미세한 금속콜로이드에 의해 착색되므로 적색의 미려한 결정화 유리를 손쉽게 제조할 수 있게 되며, 또다른 색깔의 결정화유리, 예컨대 울라스토나이트계 결정화유리와도 용이하게 융착이 가능하여 다양한 색깔을 한제품표면에 나타낼 수 있는 잇점이 있다. 또한 종래의 천연석보다 기계적 강도 및 화학적 내구성이 현저히 우수함으로서 건축물의 내.외장재로서 충분히 사용가능하다.As described above, the crystallized glass prepared by the red crystallized glass manufacturing method of the present invention forms an excellent surface pattern and a natural stone-like film, and is colored by fine metal colloids dispersed in the glass. It can be easily manufactured and can be easily fused with another colored crystallized glass, for example, an urastonite-based crystallized glass, so that various colors can be displayed on one product surface. In addition, mechanical strength and chemical durability are remarkably superior to conventional natural stone, so that it can be sufficiently used as interior and exterior materials of buildings.
이하, 본 발명을 실시예에 의거 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail with reference to Examples.
