Abstract
본 발명은 기존 차열도료 대비 근적외선 반사율 및 내후성이 향상된 친환경 수성 차열도료에 관한 것이며, 구체적으로는 나노크기의 세라믹과 백색도가 98% 이상인 이산화티탄 및 수분산 폴리우레탄 아크릴 수지를 함께 배합하여 근적외선 반사율 및 내구성을 향상시키고자 하였으며, 각종 첨가제와의 최적 배합비를 확립함에 따라 내후성, 미끄럼저항성 등 각종 물성을 향상시킨 친환경 수성 차열도료의 조성물에 관한 것이다.
본 발명의 친환경 수성의 차열도료 조성물은 나노세라믹물질인 60 ~ 300㎚ 크기의 SiO2와 백색도가 98% 이상인 이산화티탄을 함께 배합하여 근적외선 반사율을 극대화 시켰으며 동시에 수분산 폴리우레탄 아크릴 수지에 고분산되도록 배합하여 도막의 내구성, 내마모성을 및 미끄럼저항 등이 향상되는 효과를 나타낸다.
또한 본 발명에 따른 친환경 수성 차열도료는 수용성으로 시공이 편리하고 차열도료가 요구하는 기능 내지 특성인 내구성, 내후성, 미끄럼저항성 및 근적외선반사율 등을 모두 충족하므로 친환경 수성 차열도료에 적합한 특성을 지니고 있다.The present invention relates to an eco-friendly water-based heat insulating paint with improved near-infrared reflectance and weather resistance compared to existing heat insulating paints. Specifically, the present invention relates to an eco-friendly water-based heat insulating paint that has improved near infrared reflectance and weather resistance by mixing nano-sized ceramic with titanium dioxide and water-dispersed polyurethane acrylic resin with a whiteness of 98% or more. It is about a composition of an eco-friendly water-based heat insulating paint that improves durability and improves various physical properties such as weather resistance and slip resistance by establishing the optimal mixing ratio with various additives.
The eco-friendly water-based heat shielding paint composition of the present invention maximizes near-infrared reflectance by mixing SiO 2 , a nanoceramic material with a size of 60 to 300 nm, and titanium dioxide with a whiteness of 98% or more, and is highly dispersed in water-dispersed polyurethane acrylic resin. By mixing them as much as possible, the durability, abrasion resistance, and slip resistance of the coating film are improved.
In addition, the eco-friendly water-based heat insulating paint according to the present invention is water-soluble and is convenient for construction. It satisfies all of the functions and characteristics required for heat-insulating paints, such as durability, weather resistance, slip resistance, and near-infrared reflectance, making it suitable for use as an eco-friendly water-based heat-insulating paint.

상기 [표 3]의 시험 결과에 따르면 실시예1 및 실시예2에 비하여 나노세라믹 함량이 많은 실시예3의 부착강도가 표준상태 및 온냉반복 후 부착성이 가장 우수하다는 것을 확인하였다. 이는 나노세라믹이 이산화티탄에 비하여 부착성향상에 조금 더 직접적인 영향을 주는 것을 알 수 있었으며, 마찬가지로 이산화티탄 함량이 더 많은 실시예2의 조성물이 실시예1의 조성물에 비해 부착성이 우수한 것으로 보아 이산화티탄 역시 부착성에 영향을 주는 것을 확인하였다. 이중 가장 부착성이 우수하였던 실시예3에 대한 추가 물성 분석을 진행하였다.According to the test results in [Table 3], it was confirmed that the adhesion strength of Example 3, which had a higher nanoceramic content compared to Examples 1 and 2, was the best under standard conditions and after repeated hot and cold cycles. It was found that nanoceramics had a more direct effect on improving adhesion than titanium dioxide, and similarly, the composition of Example 2, which had a higher titanium dioxide content, seemed to have better adhesion than the composition of Example 1. It was confirmed that titanium also affects adhesion. Among these, additional physical property analysis was conducted on Example 3, which had the best adhesion.
