Description
본 발명은 산화티탄 광촉매 조제용 용액에 관한 것으로, 종래의 기술은 광촉매로 이산화티탄을 사용하고 용매로 물과 알콜류를 사용하여 자외선을 조사받아 광촉매 작용을 일으키게 하여왔다. 그러나 코팅 작업시 부착력이 약하고 가시광선에서는 전혀 광촉매효과를 나타내지 못하여 아직은 기술적으로 한계에 도달한 상태이다.The present invention relates to a solution for preparing a titanium oxide photocatalyst, and a conventional technique has been caused to use a titanium dioxide as a photocatalyst and water and alcohols as a solvent to irradiate ultraviolet light to cause a photocatalytic action. However, the coating has a weak adhesive force and does not show any photocatalytic effect in visible light, so the technical limit is still reached.
본 발명에서는 종래의 기술에 나타난 단점들을 제거하여, 가시광선 영역에서 광촉매 효과를 발현시키며, 콘크리트, 벽지, 가드레일등에 양호한 부착력을 제공하는 가시광촉매용액 및 제조방법을 제공하는데 있다.The present invention is to provide a visible photocatalyst solution and a method for producing a photocatalytic effect in the visible light region by removing the disadvantages shown in the prior art, and providing good adhesion to concrete, wallpaper, guardrail, and the like.
본 발명에 사용되는 방법은, 산화티탄 광촉매로 티타늄테트라이소프로폭사이드를 사용하고 망간나이트레이트를 사용하여 가시광선에서 광촉매 효과를 발현시키도록 하였다. 그리고 졸상태를 원활하게 유지하기 위하여 질산과 과산화수소를 첨가하며, 용액으로는 물과 이소프로필알콜을 사용하였다. 그리고 부착력을 높이기 위하여 메틸트리메톡시실란을 사용하여 실리옥산형태로 만들어주었다. 티타늄테트라이소프로폭사이드(A)와 망간나이트레이트(B) 사용량은 무게비로 50:1에서 1:50까지의 비율로 사용하며, 질산(C)과 과산화수소(D) 및 이소프로필알콜(E) 및 메틸트리메톡시실란(F)의 사용량은 (C)+(D)+(E)+(F)의 사용량이 (A)+(B) 사용량에 대해 무게비로 1:3에서 3:1까지의 비율로 사용한다.The method used in the present invention was to use titanium tetraisopropoxide as a titanium oxide photocatalyst and manganese nitrate to express the photocatalytic effect in visible light. In addition, nitric acid and hydrogen peroxide were added to keep the sol smooth, and water and isopropyl alcohol were used as a solution. In order to increase adhesion, methyltrimethoxysilane was used to form siloxane. The amount of titanium tetraisopropoxide (A) and manganese nitrate (B) is used in a ratio of 50: 1 to 1:50 by weight ratio, nitric acid (C), hydrogen peroxide (D) and isopropyl alcohol (E). And the amount of methyl trimethoxysilane (F) is (C) + (D) + (E) + (F) is 1: 3 to 3: 1 in weight ratio to the amount of (A) + (B) Use in proportion.
그리고 (A)+(B)+(C)+(D)+(E)+(F)는 물에 대해 무게비로 1:3에서 3:1까지의 비율로 사용하는 것을 특징으로 한다. 제조방법은 상온에서부터 90℃까지의 온도범위에서 물과 (A)+(B)+(C)+(D)+(E)+(F)를 함께 반응기에 넣고 60rpm이상으로 3시간 이상 교반시켜서 균일한 가시광촉매 코팅액을 얻는다.And (A) + (B) + (C) + (D) + (E) + (F) is characterized in that it is used in a ratio of 1: 3 to 3: 1 by weight to water. The preparation method is to put water and (A) + (B) + (C) + (D) + (E) + (F) together in the reactor in the temperature range from room temperature to 90 ℃ and stirred for more than 3 hours at 60rpm or more A uniform visible photocatalyst coating liquid is obtained.
표1은 10리터 용량의 글로브박스내에 벽면에 실시예1과 비교예1에서 비교예3까지의 코팅액을 코팅한후 형광등빛에서 2시간 경과후의 포름알데히드, 아세톤, 톨루엔, 아세트알데히드의 처리율과 벽지와 콘크리트, 스텐레스판에 부착성을 나타내었다.Table 1 shows the treatment rate and wallpaper of formaldehyde, acetone, toluene and acetaldehyde after 2 hours in fluorescent light after coating the coating solution of Example 1 and Comparative Example 1 to Comparative Example 3 on the wall in a 10 liter glove box. And adhesion to concrete and stainless steel plate.
