Description
본 발명은 단열 도료 조성물 및 이의 제조방법에 관한 것으로서, 낮은 열전도도를 가질 뿐만 아니라, 반사율이 높고, 부착강도 및 촉진내후성이 우수한 단열 도료 조성물 및 이의 제조방법에 관한 것이다.The present invention relates to an insulating paint composition and a method for manufacturing the same, which not only has low thermal conductivity, but also has a high reflectance and excellent adhesion strength and accelerated weathering resistance.
도료(페인트)는 오래전부터 개발되어 여러 용도로 다양한 조성으로 개발되어 오고 있으며, 종래에 가장 대중적으로 이용되고 있는 합성수지 도료 중 하나는 폴리우레탄 도료이다.Paint has been developed for a long time and has been developed in various compositions for various purposes, and one of the most popular synthetic resin paints is polyurethane paint.
이 폴리우레탄 도료는 폴리올과 이소시아네이트의 결합에 의한 도료로서, -NCO 기(Isocyanate Group)를 가진 성분과 -OH기(Hydroxy Group)를 가진 성분이 반응하여 -NHCOO- 구조(우레탄 결합)를 도막 속에 포함할 수 있는 도료, 또는 -NCO기와 -OH기가 이미 반응하여 -NHCOO- 구조를 가진 수지(우레탄 수지)를 바인더로 하거나 바인더의 일부로 하여 만든 도료이며, 도막의 경도가 높고, 탄성이 있어서 내마모성, 내충격성이 우수하며, 내구성, 내약 품성이 우수하여 효과가 뛰어난 도료이다.This polyurethane paint is a paint made by combining polyol and isocyanate. The component with -NCO group (Isocyanate Group) and the component with -OH group (Hydroxy Group) react to form -NHCOO- structure (urethane bond) in the paint film. It is a paint made by using a resin (urethane resin) that can contain -NCO and -OH groups already reacted to form -NHCOO- as a binder or as a part of the binder. The hardness of the coating film is high and it is elastic, so it is wear-resistant, It is an effective paint with excellent impact resistance, durability, and chemical resistance.
그러나, 이러한 합성수지도료는 실내공기를 오염시키고, 환경을 파괴하는 등의 문제가 있을 뿐만 아니라, 폴리우레탄 도료는 사용시 혼합 후부터 점도가 상승하여 결국은 경화되므로 도료의 가사시간이 있고, 도막의 내수성 때문에 상도가 하도를 잘 적시지 못해 층간박리가 일어나기도 하며, 피도물 또는 도장기구 등에 수분이 있을 경우 기포가 발생하기 쉬운 문제가 있다.However, these synthetic resin paints not only have problems such as polluting indoor air and destroying the environment, but polyurethane paints have a pot life because the viscosity increases after mixing and eventually hardens when used, and due to the water resistance of the coating film, Delamination between layers may occur because the top coat does not wet the base coat well, and if there is moisture in the object or painting equipment, bubbles can easily form.
이러한 종래의 합성수지 도료의 문제점을 극복하기 위해 최근 개발되고 있는 천연물질을 이용한 도료들은 합성수지 도료들의 독성 대신 자연향을 내고, 음이온을 발산하고, 탈취율을 높이는 등의 장점이 있지만 내구성이 떨어지고, 도막처리시 두껍게 바르면 흘러내리며 부분적으로 탈리되는 문제 등이 있다.To overcome these problems of conventional synthetic resin paints, paints using natural substances that have been recently developed have the advantages of producing a natural scent instead of the toxicity of synthetic resin paints, emitting negative ions, and increasing the deodorization rate, but are less durable and require a coating film treatment. When applied thickly, there are problems such as flowing down and partially detaching.
이에, 현재 상기 문제점을 해결하고자 하는 자연친화적인 도료의 개발이 이루어지고 있다.Accordingly, the development of nature-friendly paints to solve the above problems is currently underway.
본 발명은 상기와 같은 점을 감안하여 안출한 것으로, 낮은 열전도도를 가질 뿐만 아니라, 반사율이 높고, 부착강도 및 촉진내후성이 우수한 단열 도료 조성물 및 이의 제조방법을 제공하는데 목적이 있다.The present invention was developed in consideration of the above points, and the purpose of the present invention is to provide a heat insulating paint composition that not only has low thermal conductivity, but also has high reflectance and excellent adhesion strength and accelerated weathering resistance, and a method for producing the same.
상술한 과제를 해결하기 위하여, 본 발명의 단열 도료 조성물은 황토페이스트, 아크릴 에멀젼 수지, 이산화티타늄이 코팅된 이산화규소 중공구 입자 및 편백나무 추출물을 포함할 수 있다.In order to solve the above-described problems, the insulating paint composition of the present invention may include red clay paste, acrylic emulsion resin, titanium dioxide-coated silicon dioxide hollow sphere particles, and cypress tree extract.

하기 노출조건으로 실시예 1 ~ 9 및 비교예 1에서 제조된 단열 도료 조성물을 각각 300 시간 방치한 후, 육안으로 갈라짐, 부풂, 떨어짐, 색변화 등을 관찰하여 5점 척도로 측정하고 그 결과를 표 1로 나타내었다(점수가 높을수록 도료의 들뜸, 크랙, 갈라짐 등이 거의 나타나지 않는 것으로 평가하였고, 점수가 낮을수록 도료의 들뜸, 크랙, 갈라짐이 많이 발생하는 것을 평가하였다.).After leaving the insulating paint compositions prepared in Examples 1 to 9 and Comparative Example 1 for 300 hours each under the following exposure conditions, cracking, swelling, falling off, color change, etc. were observed with the naked eye, measured on a 5-point scale, and the results were reported. It is shown in Table 1 (the higher the score, the less peeling, cracking, or splitting of the paint appears; the lower the score, the more peeling, cracking, or splitting of the paint occurs.)
