일반적으로 일반 가정이나 숙박시설에는 거울을 포함하는 세면시설, 변기 및 욕조가 설치되어 있는 욕실을 사용하고 있다. 또한, 욕조를 대신하여 샤워부스가 설치되기도 한다.In general, homes and accommodations use bathrooms with mirrors, toilets, toilets and bathtubs. In addition, a shower booth may be installed in place of the bathtub.
따라서, 상기 욕실 내 샤워부스, 거울, 세면기 등은 항상 물에 노출되어 있으므로, 물 또는 물에 용해되어 있거나 혼합되어 있는 오염물질에 의해 쉽게 오염된다.(물이끼, 물때 등)Therefore, the shower booth, mirror, wash basin, etc. in the bathroom are always exposed to water, and thus are easily contaminated by water or contaminants dissolved or mixed in the water (water moss, scale, etc.).
종래 이러한 욕실 물품의 오염을 방지하기 위하여, 발수성을 부여하는 욕실용 코팅제 조성물을 사용하여 욕실 물품, 특히 유리의 표면을 코팅하는 방법이 제안되었다. In order to prevent contamination of such bathroom articles, a method of coating a surface of a bathroom article, in particular glass, using a coating composition for a bathroom to impart water repellency has been proposed.
이러한 코팅제 조성물은 아미노 변성 폴리실록산을 주성분으로 하는 것이 대부분이다. 상기 아미노 변성 폴리실록산을 주성분으로 하는 코팅제 조성물은 유리에 대한 코팅작업이 용이하고, 제품에 수분이 포함되어 있거나 처리면에 수분이 존재하고 있을 때에도 사용할 수 있다는 장점이 있다. 그러나 이러한 코팅제 조성물은 친수성기인 아미노기를 포함하고 있으므로, 발수성이 떨어지며, 지속성이 수 시간에서 수 주일 정도로 짧아서 자주 코팅해야 하는 번거로움이 있다. 또한, 이러한 코팅제는 발수성만을 개선할 뿐, 방오성, 발유성, 내구성, 내부식성 등의 기능은 없는 단점도 있다.Such coating compositions are mostly based on amino modified polysiloxanes. The coating composition based on the amino-modified polysiloxane has an advantage that it is easy to coat the glass and can be used even when the product contains water or water is present on the treated surface. However, since the coating composition includes an amino group that is a hydrophilic group, water repellency is poor, and the durability is short enough for several hours to several weeks, so that it is cumbersome to coat frequently. In addition, the coating agent only improves the water repellency, there is also a disadvantage that there is no function, such as antifouling properties, oil repellency, durability, corrosion resistance.
따라서, 유리 등의 코팅제 조성물로서 장기간에 걸쳐 우수한 발수성을 나타냄은 물론, 방오성, 발유성, 내구성, 내부식성 등의 개선이 가능한 코팅제 조성물이 요구되고 있다. Accordingly, there is a demand for a coating composition capable of exhibiting excellent water repellency over a long period of time as a coating composition such as glass, as well as improving antifouling properties, oil repellency, durability, and corrosion resistance.
따라서, 본 발명의 목적은 상기한 종래의 코팅제 조성물이 갖는 제반 문제점을 해소하기 위한 것으로, 이소프로필 알콜, 무기산 및 히드록시메틸 말단의 실리콘 폴리머 포함하는 코팅제 조성물을 이용하여 욕실용 유리 표면을 소수성으로 바꿈으로써, 유리의 발수성 및 방오성을 개선하는 것이다.Accordingly, an object of the present invention is to solve all the problems of the conventional coating composition described above, and to make the glass surface of the bathroom hydrophobic by using a coating composition containing isopropyl alcohol, an inorganic acid, and a hydroxymethyl-terminated silicone polymer. By changing, it is to improve the water repellency and antifouling property of glass.
또한, 발유성, 내구성, 내부식성 등을 개선함은 물론, 한 번의 코팅만으로 5년 이상의 그 특성이 유지되도록 하는 것이다.In addition, to improve oil repellency, durability, corrosion resistance, and of course, to maintain its properties for more than five years with a single coating.
상기한 목적을 달성하기 위한 본 발명의 욕실용 유리 코팅제 조성물은, 이소프로필 알콜, 무기산 및 히드록시메틸 말단의 실리콘 폴리머(Siloxanes and silicones, di-Me, hydroxymethyl-terminated-)를 포함하는 것을 특징으로 한다.Glass coating composition for a bathroom of the present invention for achieving the above object, is characterized in that it comprises isopropyl alcohol, inorganic acid and hydroxymethyl terminal silicone polymer (Siloxanes and silicones, di-Me, hydroxymethyl-terminated-) do.
상기 이소프로필 알콜 85~95중량%, 무기산 0.1~1중량% 및 히드록시메틸 말단의 실리콘 폴리머 4.9~14중량%를 포함하는 것을 특징으로 한다.It is characterized in that it comprises 85 to 95% by weight of the isopropyl alcohol, 0.1 to 1% by weight of inorganic acid and 4.9 to 14% by weight of the hydroxymethyl terminal silicone polymer.
상기 무기산은 0.1~1N의 황산수용액인 것을 특징으로 한다.The inorganic acid is characterized in that the aqueous solution of sulfuric acid of 0.1 ~ 1N.
그리고 본 발명에 의한 욕실용 유리 코팅방법은, 유리 표면을 세척하는 단계와, 상기 세척된 유리의 표면에 유리의 표면에 상기한 코팅제 조성물을 도포하는 단계와, 상기 코팅제 조성물이 도포된 유리를 5~15분간 방치한 후, 버핑용 타올로 버핑(buffing)하는 단계와, 상기 버핑된 유리를 2~12시간 경화시키는 단계를 포함하는 것을 특징으로 한다.And glass coating method for a bathroom according to the present invention, the step of washing the glass surface, the step of applying the coating composition to the surface of the glass on the surface of the washed glass, and the glass coated with the coating composition 5 After leaving for 15 minutes, buffing (buffing) with a buffing towel, and characterized in that it comprises the step of curing the buffed glass for 2 to 12 hours.

본 발명에 의하면, 유리 표면에 발수성은 물론, 방오성, 발유성, 내구성, 내부식성 등의 특성을 부여할 수 있다는 장점이 있다. 또한, 한 차례의 시공만으로 5년 이상 그 특성을 유지할 수 있다는 장점이 있다. According to the present invention, there is an advantage in that the glass surface can be provided with properties such as antifouling property, oil repellency, durability, and corrosion resistance. In addition, there is an advantage that can maintain its characteristics for more than five years with only one construction.
도 1은 본 발명에 의한 유리의 코팅방법을 나타낸 순서도.1 is a flow chart showing a coating method of glass according to the present invention.
이하, 본 발명을 상세히 설명한다.Hereinafter, the present invention will be described in detail.
유리는 대부분 친수성 표면을 나타낸다. 친수성 유리표면은 물방울이나 수분 또는 먼지 등의 오염물질이 쉽게 부착되는 표면특성을 나타낸다.Glass mostly exhibits hydrophilic surfaces. Hydrophilic glass surfaces exhibit surface characteristics to which contaminants such as water droplets, moisture, and dust easily adhere.
따라서, 본 발명은 친수성 표면의 유리와 직접적으로 반응하여 표면의 물성을 소수성으로 바꿈으로써, 유리의 방오성, 발유성, 내구성 및 내부식성의 특성을 개선하고자 하는 것이다. Therefore, the present invention is intended to improve the properties of the antifouling property, oil repellency, durability and corrosion resistance of the glass by directly reacting with the glass of the hydrophilic surface to change the physical properties of the surface to hydrophobic.
이를 위한 본 발명의 코팅제 조성물은, 이소프로필 알콜, 무기산 및 히드록시메틸 말단의 실리콘 폴리머(Siloxanes and silicones, di-Me, hydroxymethyl-terminated-)를 포함하는 것을 특징으로 한다.The coating composition of the present invention for this purpose is characterized in that it comprises isopropyl alcohol, inorganic acid and hydroxymethyl terminal silicone polymer (Siloxanes and silicones, di-Me, hydroxymethyl-terminated-).
먼저, 상기 이소프로필 알콜(2-Propanol)은 용매로서 사용되는 것으로, 무기산 및 히드록시메틸 말단의 실리콘 폴리머를 용해시키는 작용을 한다. First, the isopropyl alcohol (2-Propanol) is used as a solvent, and serves to dissolve the inorganic acid and the silicone polymer of the hydroxymethyl terminal.
상기 이소프로필 알콜은 코팅제 조성물 내 85~95중량%의 범위로 포함됨이 바람직한데, 상기 용매의 양이 너무 적으면 무기산 및 히드록시메틸 말단의 실리콘 폴리머의 용해가 어렵고, 사용성이 좋지 않으며, 균일한 코팅이 어렵고, 상기 용매의 양이 너무 많으면 발수성, 방오성 등의 특성을 충분히 향상시킬 수 없기 때문이다.The isopropyl alcohol is preferably included in the range of 85 to 95% by weight in the coating composition. If the amount of the solvent is too small, it is difficult to dissolve the inorganic acid and the hydroxymethyl-terminated silicone polymer, and the usability is good. This is because coating is difficult and when the amount of the solvent is too large, properties such as water repellency and antifouling property cannot be sufficiently improved.
상기 무기산은 상기 코팅제 조성물이 유리 표면과 반응할 시 촉매제로서 작용하는 것으로, 구체적으로는 황산을 이용할 수 있다. 이때, 상기 황산은 취급의 용이성을 위하여 0.1~1N 농도의 수용액을 사용함이 바람직하다.The inorganic acid acts as a catalyst when the coating composition reacts with the glass surface. Specifically, sulfuric acid may be used. At this time, the sulfuric acid is preferably used for the aqueous solution of 0.1 ~ 1N concentration for ease of handling.
상기 무기산은 코팅제 조성물 내 0.1~1중량%로 포함됨이 바람직한데, 상기 무기산의 양이 너무 적으면 촉매로서의 작용이 어렵고, 상기 무기산의 양이 너무 많으면 과량이 되어 코팅제 조성물의 물성에 좋지 않은 영향을 미치기 때문이다. The inorganic acid is preferably contained in 0.1 to 1% by weight in the coating composition, if the amount of the inorganic acid is too small, it is difficult to act as a catalyst, if the amount of the inorganic acid is too large is excessive to affect the physical properties of the coating composition. Because it's crazy.
그리고 히드록시메틸 말단의 실리콘 폴리머(Siloxanes and silicones, di-Me, hydroxymethyl-terminated-)는 친수성인 유리 표면과의 반응을 통해 유리 표면을 소수성으로 바꿔주는 성분으로, 구체적으로는 CAS No. 73138-87-1의 화합물을 사용할 수 있다. 또한, 상기 히드록시메틸 말단의 실리콘 폴리머는 이러한 화학작용을 통해 발수성뿐 아니라, 방오성, 발유성, 내구성, 내부식성 등의 특성도 부여한다는 특징이 있다. Hydroxymethyl-terminated silicone polymer (Siloxanes and silicones, di-Me, hydroxymethyl-terminated-) is a component that converts the glass surface into hydrophobic through reaction with a hydrophilic glass surface, specifically CAS No. The compounds of 73138-87-1 can be used. In addition, the hydroxymethyl terminal silicone polymer is characterized by imparting properties such as antifouling property, oil repellency, durability, corrosion resistance, as well as water repellency through this chemical action.
상기 히드록시메틸 말단의 실리콘 폴리머는 코팅제 조성물 내 4.9~14중량%의 범위로 포함됨이 바람직한데, 그 함량이 4.9중량% 미만일 경우 유리 표면을 충분히 소수성으로 바꿔줄 수 없어 발수성이 향상 효과가 미미하게 되고, 14중량%를 초과하면 과량이 되어 추가적인 물성 향상의 효과는 미미하면서도 코팅제 조성물의 사용성, 안정성 등이 떨어지기 때문이다.The hydroxymethyl-terminated silicone polymer is preferably included in the range of 4.9 to 14% by weight in the coating composition, when the content is less than 4.9% by weight can not change the glass surface sufficiently hydrophobic so that the effect of improving water repellency is minimal If it exceeds 14% by weight, it becomes excessive, because the effect of further improving physical properties is insignificant, but the usability, stability, etc. of the coating composition are inferior.
상기와 같이 구성되는 본 발명의 욕실용 유리 코팅제 조성물은, 유리 표면에 도포하는 것만으로 유리 표면의 초미세 균열에 따라 나노단위의 융곡을 메우고 뿌리를 내려, 유리성분인 이산화규소와의 직접적인 화학반응을 통해 유리 표면의 물성을 소수성으로 바꿔줌으로써, 발수성, 방오성, 발유성, 내구성, 내부식성 등을 개선하는 것이다.The glass coating composition for a bathroom of the present invention constituted as described above is filled with nano-united valleys and rooted according to the ultrafine cracks on the glass surface, and is directly chemically reacted with silicon dioxide as a glass component. By changing the properties of the glass surface to hydrophobic through, to improve the water repellency, antifouling properties, oil repellency, durability, corrosion resistance and the like.
본 발명은 욕실에 적용되는 샤워부스, 유리 샤워 스크린, 거울 등의 유리는 물론, 욕실이 아닌 기타 유리가 적용되는 모든 물품, 예시적으로 유리 파사드, 유리 지붕, 태양광 패널, 건물 외창 등에 사용도 가능함은 당연하다.The present invention is not only used for the glass, such as shower booth, glass shower screen, mirror applied to the bathroom, but also all other items to which glass is applied, such as glass facades, glass roofs, solar panels, building windows, etc. Of course it is possible.
