본 발명은 알코올, 티탄화합물 및 안정화제로 된 티탄화합물 분산 졸(a)과 알코올, 규소화합물 및 안정화제로 된 규소화합물 바인더(b)를 포함하는 오염방지 코팅 조성물에 관한 것이다.The present invention relates to an antifouling coating composition comprising a titanium compound dispersion sol (a) of alcohol, titanium compound and stabilizer and a silicon compound binder (b) of alcohol, silicon compound and stabilizer.

상기 본 발명의 오염방지 코팅 조성물은 티탄화합물 분산 졸(a)과 규소화합물 바인더(b)를 혼합한 것으로서, 건축 내장재의 천장이나 벽의 마감재로 사용되는 아연도강판이나 알루미늄 복합판넬, PC 판넬과 같은 판넬 등에 코팅하여 오염방지, 공기정화 등의 기능을 갖는다.The antifouling coating composition of the present invention is a mixture of a titanium compound dissolving sol (a) and a silicon compound binder (b), and the galvanized steel sheet or aluminum composite panel, PC panel and the like used as a finishing material of the ceiling or wall of building interior materials Coating on the same panel has functions such as pollution prevention and air purification.

알루미늄, 강철 및 스텐레스 스틸과 같은 재질로 만들어진 판넬은 건축 내외 장재로 흔히 사용되어 오고 있다. 이러한 판넬이 건축 내장재로 사용될 경우, 그 표면이 먼지 등에 의해 오염될 뿐 아니라, 세균, 곰팡이 등이 증식되어 호흡기 질환 및 위생에 유해한 요소로 작용하고 있다. Panels made of materials such as aluminum, steel and stainless steel have been commonly used for interior and exterior construction. When such a panel is used as a building interior material, not only the surface is contaminated by dust, etc., but also bacteria, mold, etc. are proliferating, which acts as a harmful factor for respiratory diseases and hygiene.

이러한 문제점을 극복하기 위하여, 최근에 이산화티탄 등의 광촉매가 코팅된 판넬이 개발되어 왔으나, 사용된 이산화티탄 코팅액은 도포한 후 100℃ 이상의 고온에서 열처리를 해야 하거나, 코팅액에 분산되어 있는 이산화티탄 입자가 균질하지 않아서 도포후 판넬에 형성된 코팅층의 투명도가 떨어지는 문제점이 있었다. 또한 종래의 이산화티탄 코팅액의 pH가 강산성이여서 코팅 과정 등의 작업이 작업자에게 매우 유해하였다.In order to overcome this problem, a panel coated with a photocatalyst such as titanium dioxide has recently been developed, but the titanium dioxide coating liquid used must be heat-treated at a high temperature of 100 ° C. or higher, or the titanium dioxide particles dispersed in the coating liquid. There was a problem that the transparency of the coating layer formed on the panel after the coating is not homogeneous because it is not uniform. In addition, since the pH of the conventional titanium dioxide coating solution is strongly acidic, the work such as coating process is very harmful to the operator.

본 발명자들은 이와 같은 종래의 이산화티탄 코팅된 판넬의 문제점을 해결하고자 연구를 계속한 결과, TiO2-SiO2 코팅액으로 판넬을 코팅함으로써 오염방지, 공기정화 등의 기능을 갖는 오염방지 코팅 조성물을 발명하기에 이르렀다.The inventors of the present invention continue to solve the problems of the conventional titanium dioxide coated panel, as a result of coating the panel with a TiO 2 -SiO 2 coating solution invented an antifouling coating composition having a function of antifouling, air purification, etc. It came to the following.

즉, 본 발명의 목적은 오염방지, 공기정화 등의 기능을 갖는 조성물로서, 상온에서 경화되는, 아연도강판이나 판넬용 TiO2-SiO2 코팅 조성물을 제공하는 것이다.That is, an object of the present invention is to provide a TiO 2 -SiO 2 coating composition for galvanized steel sheet or panel, which is cured at room temperature as a composition having functions such as pollution prevention and air purification.

상기한 목적을 위하여 본 발명에서는 TiO2-SiO2 코팅 조성물로서, 알코올, 티탄화합물 및 안정화제로 된 티탄화합물 분산 졸(a)과 알코올, 규소화합물 및 안정화제로 된 규소화합물 바인더(b)를 포함하는 것을 특징으로 한다. For the above purpose, the present invention provides a TiO 2 -SiO 2 coating composition comprising a titanium compound dispersion sol (a) of alcohol, titanium compound and stabilizer and a silicon compound binder (b) of alcohol, silicon compound and stabilizer. It is characterized by.

여기서, 상기 티탄화합물 분산 졸(a)은 알코올 85~98.9 중량%, 티탄화합물 1~12 중량% 및 안정화제 0.1~3 중량%로 이루어지고, 상기 규소화합물 바인더(b)는 알코올 87~98.9 중량%, 규소화합물 1~10 중량% 및 안정화제 0.1~3 중량%로 이루어진 것이 바람직하다.Here, the titanium compound dispersion sol (a) is composed of 85 to 98.9% by weight of alcohol, 1 to 12% by weight of titanium compound and 0.1 to 3% by weight of stabilizer, the silicon compound binder (b) is 87 to 98.9% by weight of alcohol %, Silicon compound 1 to 10% by weight and stabilizer 0.1 to 3% by weight is preferable.

또한, 상기 티탄화합물 분산 졸(a)과 규소화합물 바인더(b)는 1:1~10(중량비)로 이루어진 것이 적당하다.In addition, the titanium compound dispersion sol (a) and the silicon compound binder (b) is preferably composed of 1: 1 to 10 (weight ratio).

본 발명의 조성물이 적용되는 판넬의 광촉매 구조는 소수성인 아연도강판 판넬에 실란(silane)계열의 바인더와 광촉매 활성을 갖는 이산화티탄이 공유 결합하여 형성되는 층으로 구성되는 것이다.The photocatalyst structure of the panel to which the composition of the present invention is applied is composed of a layer formed by covalent bonding of a silane-based binder and titanium dioxide having photocatalytic activity to a hydrophobic galvanized steel panel.

본 발명에서 사용되는 상온에서 경화되는 TiO2-SiO2 코팅 조성물은 나노미립자 형태의 티탄화합물이 1~12 중량%로 분산되어 있고, 산촉매로 많이 사용되는 무기산 또는 이들의 혼합물로부터 선택되는 안정화제가 0.1~3 중량% 포함되고, 상기 코팅 조성물의 접착력을 증가시킬 수 있는 규소화합물 및 용매인 알코올을 포함하는 것을 특징으로 한다.The TiO 2 -SiO 2 coating composition cured at room temperature used in the present invention has a titanium compound in the form of nanoparticulates dispersed at 1 to 12% by weight, and a stabilizer selected from inorganic acids or mixtures thereof, which are widely used as acid catalysts, is 0.1. It includes 3 wt%, it characterized in that it comprises a silicon compound and a solvent alcohol that can increase the adhesion of the coating composition.

상기 알코올은 메탄올, 에탄올, 프로판올, 이소프로판올, 부탄올과 같은 C1-C4의 저급 알코올이다.The alcohol is a C1-C4 lower alcohol such as methanol, ethanol, propanol, isopropanol, butanol.

상기 안정화제는 바람직하기는 산촉매로 많이 사용되는 질산, 염산 등의 무기산이나 또는 이들의 혼합물을 포함할 수 있다. 안정화제의 첨가량은 안정화제의 분자량에 따라 달라질 수 있으며, 대체로 생성되는 티탄화합물 콜로이드 용액을 100중량%로 할 때, 0.1중량% 이상이면 되는데, 0.1중량% 이하이면 안정화 작용이 충분하지 않아 입자가 커지게 된다. 바람직하게는 1~3중량%로 첨가하는 것이 좋은데, 3중량% 이상이면 비용이 많이 들게 된다.The stabilizer may include inorganic acids such as nitric acid and hydrochloric acid, or mixtures thereof, which are preferably used as acid catalysts. The amount of stabilizer added may vary depending on the molecular weight of the stabilizer. When the titanium compound colloidal solution is generally 100% by weight, the amount of stabilizer may be 0.1% by weight or more, but 0.1% by weight or less may not be sufficient to stabilize the particles. It becomes bigger. Preferably it is good to add 1 to 3% by weight, it is expensive if more than 3% by weight.

상기 규소화합물로는 물유리(Water glass, Sodium silicate), TEOS(Tetra-ethyl orthosilicate), TMOS(Tetra-methyl orthosilicate) 또는 이들의 혼합물을 들 수 있다. 유기규소 산화물을 추가로 포함할 경우, 판넬에 대한 밀착성은 더욱 향상된다.The silicon compound may include water glass (Sodium silicate), Tetra-ethyl orthosilicate (TEOS), Tetra-methyl orthosilicate (TMOS), or a mixture thereof. When the organosilicon oxide is further included, the adhesion to the panel is further improved.

상기 티탄화합물은 이산화티탄 화합물로서 티타늄(Ⅳ) 이소프로폭사이드 (테트라이소프로판올티탄), 티타늄(Ⅳ) 부톡사이드, 티타늄(Ⅳ) 에톡사이드 (티탄테트라에탄올레이트), 티타늄(Ⅳ) 메톡사이드, 티타늄(Ⅳ) 스티어레이트, 또는 이들의 혼합물이 바람직하다. The titanium compound is a titanium dioxide compound as titanium (IV) isopropoxide (tetraisopropanol titanium), titanium (IV) butoxide, titanium (IV) ethoxide (titanium tetraethanolate), titanium (IV) methoxide, titanium (IV) Stearates or mixtures thereof are preferred.

이산화티탄 화합물은 코팅 조성물에서 생성되는 나노미립자 형태의 이산화티탄이 1~12 중량%의 농도가 되도록 환산하여 첨가한다. 이산화티탄 나노미립자 분산량이 1 중량% 이하이면 코팅시 적절한 코팅층이 형성되지 않고, 12 중량% 이상을 분산시킨 용액은 분산된 이산화티탄 나노 콜로이드가 응집되어 입자가 커질 수 있으므로 상기 분산범위가 적절하다.The titanium dioxide compound is added in conversion so that the concentration of nanoparticles of titanium dioxide produced in the coating composition is 1 to 12% by weight. If the dispersion amount of titanium dioxide nanoparticles is less than 1% by weight, an appropriate coating layer is not formed during coating, and a solution having 12% by weight or more dispersed therein is suitable because the dispersed titanium dioxide nanocolloids may aggregate to increase the particle size.

또한, 상기 티탄화합물 분산 졸(a)과 규소화합물 바인더(b)는 1:1~10(중량 비)로 이루어진 것이 적당하다.In addition, the titanium compound dispersion sol (a) and the silicon compound binder (b) is preferably composed of 1: 1 to 10 (weight ratio).

여기서 상기 티탄화합물 분산 졸(a)에 비해 규소화합물 바인더(b)의 함량이 적으면 코팅 후 접착력의 약화로 인해 장기간의 오염방지 효과를 가질 수 없어 좋지 않고, 규소화합물 바인더(b)의 함량이 10(중량비) 이상이면 코팅 후 판넬 일부의 박리 현상이 나타날 수 있어 좋지 않다.Here, when the content of the silicon compound binder (b) is less than that of the titanium compound dispersing sol (a), it is not good to have a long-term contamination prevention effect due to the weakening of the adhesive strength after coating, and the content of the silicon compound binder (b) is not good. If it is 10 (weight ratio) or more, it may not be good to peel off a part of the panel after coating.

또한, 필요에 따라, 상기 이산화티탄 화합물과 함께 규소 화합물, 알루미늄 화합물, 지르코늄 화합물, 철 화합물 또는 이들의 혼합물을 첨가하여 반응시킬 수도 있다.  In addition, if necessary, a silicon compound, an aluminum compound, a zirconium compound, an iron compound, or a mixture thereof may be added and reacted with the titanium dioxide compound.

상기 본 발명의 오염방지 코팅 조성물은 하기의 단계로 제조될 수 있다.The antifouling coating composition of the present invention may be prepared by the following steps.

A) 알코올에 티탄화합물과, 알코올기와 케톤기를 갖는 유기산 및 이들의 염으로부터 선택되는 안정화제를 순차적으로 첨가하여 Sol-gel 반응시켜 티탄화합물 분산 졸(a)을 얻는 단계;A) sequentially adding a titanium compound, a stabilizer selected from an organic acid having an alcohol group and a ketone group, and a salt thereof to a alcohol to perform a Sol-gel reaction to obtain a titanium compound dispersion sol (a);

이하, 제조예 및 실시예를 통하여 본 발명의 구성을 좀더 상세히 설명한다.Hereinafter, the configuration of the present invention through the production examples and examples in more detail.
