Since then, many energy-saving technologies and technologies for maximizing energy efficiency have been developed, and many large corporations and public research institutes are in progress.

나노 입자란 입자의 지름이 나노미터(1-100㎚) 수준의 크기를 가지는 것을 의미한다. 이 크기에서 물질을 거대 집합 상태의 금속과 분자 상태의 중간 단계에 해당하며, 이러한 상태에 있는 물질들은 동일한 화학적 조성임에도 불구하고 급격히 늘어난 비표면적과 양자역학적 효과에 의해 벌크 상태와는 전혀 다른 광학적, 전자기적 성질을 나타낸다.Nanoparticles means that the diameter of the particles having a size of the nanometer (1-100nm) level. At this size, the material is an intermediate stage between the metal and molecular states of the macromolecular state, which, despite their identical chemical composition, are dramatically different from the bulk state due to their rapidly increasing specific surface area and quantum mechanical effects. It exhibits electromagnetic properties.

나노기술은 세계적으로 많은 연구가 이루어지고 있고 이것은 원자와 분자 수준에서 관리할 목적으로 원자나 분자 물질의 그 물성을 이용하여 성장 또는 분리,감소 입자로 조작하는 기술이다. 나노기술의 설계와 제조는 고도의 기술이 필요하며, 나노화를 진행하데, 그의 물성이 존재해야 하고 나노라 칭하는 물질은 모든 3차원에서 0.4㎚(400㎚) 이하의 입자를 말하며, 예를 들면 100 나노미터의 입자는 0.1um이고 100나노미터(100x10-9m)이하의 치수를 가진다.Nanotechnology is being researched around the world, and it is a technology that manipulates the growth, separation and reduction particles using the properties of atoms or molecular materials for the purpose of managing at the atomic and molecular level. The design and manufacture of nanotechnology requires a high level of skill and proceeds with nanotechnology, the properties of which must be present and the material called nano refers to particles below 0.4 nm (400 nm) in all three dimensions, for example 100 The nanometer particles are 0.1 um and have dimensions less than 100 nanometers (100x10 -9 m).

최근에는 나노기술을 이용한 코팅제와 발수제가 개발되고 있으나, 대부분 친환경적이 못하여 사용에 제약이 수반되었다.Recently, coatings and water repellents using nanotechnology have been developed, but most of them are not environmentally friendly and have been constrained for use.

종래 나노 또는 일반 코팅제는 적용시 화학적 반응으로 인한 변질, 변색, 백화 현상 등의 여러 가지 문제점이 있다. 여러 번 반복하여 도포를 해야만 어느 정도의 효과나 기능성을 갖는다. 현재 시중에 판매되고 있는 코팅제 또는 발수제는 화학약품으로 법적으로 외부 스프레이 도포는 할 수 없다.Conventional nano or general coatings have various problems such as deterioration, discoloration, and whitening due to chemical reactions during application. Repeated application several times has some effect or functionality. Commercially available coatings or water repellents are chemicals and cannot be applied externally by law.

통상적으로 건물 외벽에 적용하는 발수제에서 기능적 지속성을 1~2년이라고 하는데 실질적 그 기능은 6개월 정도 내외이다. 일반적 화학제로서 강하고 자극적인 휘발성 냄새가 난다. 기본적으로 자외선이 차단되지 않으며, 간혹 자외선 차단되는 제품은 있으나 그것은 발수 기능이 거의 없다.In general, the functional continuity in the water repellent applied to the exterior wall of a building is 1 to 2 years, and its function is about 6 months. As a general chemical, it has a strong and irritating volatile odor. Basically, UV rays are not blocked, and there are some products that block UV rays, but they have little water repellency.

현재 시중에 나와있는 대부분의 제품은 통기성이 좋으면 오염물질 예방 기능이 떨어지고 오염물질 예방 기능이 좋으면 통기성이 떨어진다. 자연적 표면이나 질감을 갖지 못한다. 적용범위가 한정적이다 열에 대한 저항력이 약하다. 마모 저항력이 약하다. 직물에 적용되는 기존 발수제는 열을 가하여만 가능하다. 기존 제품은 많은 양을 사용하여야 한다. 사용이 불편하고, 보관상 화기 위험성이 있어 안전성에 문제가 있다.Most of the products on the market are less contaminant preventive function if the breathability is good, and less breathable if the pollutant prevention function is good. It has no natural surface or texture. The scope of application is limited The resistance to heat is weak. Abrasion resistance is weak. Existing water repellents applied to the fabric can only be heated. Existing products must be used in large quantities. Inconvenient to use, there is a risk of fire in storage, there is a safety problem.

이상에서 설명한 바와 같이, 본 발명은 순수 물을 기준으로 제조되어 친환경적이며, 화학 저항력 및 안정성이 있으며, PH 13까지 용해되지 않는다. 피복체의 표면 에너지를 보강하며 표질 에는 변화를 주지 않고 오염물을 방지한다. CBA 성적서로 증명 식품에 무해하고 “KOTITI”성적서로 인체에 무해함을 증명하였다. 100㎚의 입자로 구성되어 표면이 아닌 적용물 입자에 코팅층이 이루어져 통기성을 유지한다. 자외선 차단, 마모 저항력이 뛰어나 반영구적이다. SiO2의 기본 성질과 초결정체로 이루어져 굴절이 일어나기 때문에 자외선 차단에 효과적이다. 450℃ 이내로 내열성이 있으며, 무색 무취이며 비 화학성이기 때문에 변질과 변색이 없다. 약 50~60 bar 압력까지 견디어 마모성이 뛰어나다. 화학 저항력이 PH13까지 용해되지 않기 때문에 부식을 방지하고 화학 변화를 갖지 않는다. 내구성이 높고 사용이 용이하고 취급이 간편하다. 접사면 각도는 유리류, 플라스틱류(105˚~109˚), 직물류, 광물류(125˚~134˚)로 설정된다. 화학적 변화가 없고 무색 무취여서 실내외 모두 사용이 가능하다. 페인트와 오일스테인이 되어있어도 나노 코팅이 가능하다.As described above, the present invention is manufactured on the basis of pure water, is environmentally friendly, has chemical resistance and stability, and does not dissolve until PH 13. It reinforces the surface energy of the coating and prevents contaminants without changing the surface quality. CBA test report proved harmless to food and “KOTITI” test report. It is composed of particles of 100 nm, the coating layer is applied to the particles of the application rather than the surface to maintain breathability. It is semi-permanent with excellent UV protection and abrasion resistance. It is effective in blocking UV rays because of refraction caused by the basic properties of SiO 2 and supercrystals. It is heat-resistant within 450 ℃, colorless and odorless and non-chemical, so there is no alteration and discoloration. Withstands pressure up to 50 ~ 60 bar and has excellent wear resistance. Since chemical resistance does not dissolve until PH13, it prevents corrosion and has no chemical change. Durable, easy to use and easy to handle. Macro angle is set to glass, plastics (105˚ ~ 109˚), textiles, minerals (125˚ ~ 134˚). It has no chemical change and is colorless and odorless so it can be used indoors and outdoors. Nano coating is possible even with paint and oil stain.
