At this time, the silicone-modified acrylic resin and the monomer are preferably mixed at a weight ratio of 1:0.3 to 1:0.7. If the amount of monomer used is outside the critical range, that is, if it is used excessively, the cured state may be unstable during surface coating, and the surface coating layer may not be smoothly formed and may become uneven, causing curls, and if used too insufficiently, the monomer may be unstable. In this case, the bonding power of the surface coating may decrease, causing cracks and film delamination.
본 발명에 따르면, 상기 모노머는 디펜타에리스리톨 헥사아크릴레이트(Dipentaerythritol Hexaacrylate)와 N,N-디메틸아크릴 아마이드(N,N-Dimethylacrylamide)를 1:0.5 내지 1:1의 중량비로 혼합한 혼합물을 사용하는 것에 그 특징이 있다.

상기 광개시제는 일정 첨가량을 배합할 경우 자외선 조사 시 상기 모노머가 라디칼 반응하여 폴리머로 결합하게 되는 것으로, 만일 그 사용량이 0.9중량부 미만일 경우에는 표면코팅시 경화시간이 매우늦어지거나, 경화가 잘 안되는 문제가 있을 수 있고, 1.5중량부를 초과할 경우에는 표면코팅시 단량체 발생이 증가하여 결합력이 저하될 수 있는 문제가 있다. When the photoinitiator is mixed in a certain amount, the monomer undergoes a radical reaction and combines into a polymer when irradiated with ultraviolet rays. If the amount used is less than 0.9 parts by weight, the curing time during surface coating is very slow, or curing is difficult. There may be a problem that, if it exceeds 1.5 parts by weight, the generation of monomers increases during surface coating, which may reduce the bonding strength.

According to the present invention, the dispersant is added to improve the slip and dispersibility of the composition, and 2-propenoic acid, butyl ester is preferably used. If the amount used is less than 0.05 parts by weight, blocking may occur due to insufficient surface slip, and the appearance of the coating may become uneven and deteriorated. If it exceeds 0.1 parts by weight, excessive surface slip and product haze may increase. There may be. When the haze increases, there is a problem of decreased transparency due to the milky phenomenon. Preferably, the haze value is 2.0 or less to ensure transparency.

According to the present invention, the heat barrier agent is antimony tin oxide containing 30 to 40% by weight of solids nano-dispersed to have a particle size of 50 nm or less in an organic solvent and a particle size of 50 nm or less in an organic solvent. A liquid mixture of cesium tungsten oxide containing 30 to 40% by weight of solids nano-dispersed to have a particle size at a weight ratio of 1:0.85 to 1:0.95 is used. More preferably, each component constituting the heat barrier agent is a liquid solid content having a particle size of 50 nm or less and nano-dispersed in an organic solvent such as methyl ethyl ketone.
이때, 상기 열차단제의 사용량이 70중량부 미만일 경우에는 기대하는 열차단 물성 부족으로 열차단 상용성의 저하로 열차단 효과가 미미한 단점이 있고, 80중량부를 초과할 경우에는 코팅층의 내구성이 저하될 뿐만 아니라 코팅층에 크랙이 발생하는 문제가 있을 수 있다. At this time, if the amount of the heat barrier used is less than 70 parts by weight, the thermal barrier effect is minimal due to a decrease in heat barrier compatibility due to the lack of expected heat barrier properties, and if it exceeds 80 parts by weight, the durability of the coating layer is reduced. However, there may be a problem of cracks occurring in the coating layer.
상기 열차단 첨가제로 사용되는 열차단제는 상기 모노머에 비례하여 임계치 범위 내에서 첨가량을 조절하여 코팅제 조성물의 설계가 가능하다. It is possible to design a coating composition by adjusting the amount of the heat barrier used as the heat barrier additive within a critical range in proportion to the monomer.
