To Prepare an anti-corrosive and weather-resistant coating, an acrylic coating containing alkoxysilane, alkoxysilyl-functional acrylic groups, and tertiary amine was synthesized by a radical polymerization. The composition of monomers was adjusted to have the glass transition temperature of acrylic polymer at 30 ℃. The composition of alkoxysilane in the synthesized polymer was varied from 10 wt% to 30 wt%, and di-n-butyltindilaurate (DBTDL) was used as the curing agent. Epoxysilane's content, for curing agents of acrylic resins containing tertiary amine, was varied from 5 wt% to 15 wt%. On the basis of synthesized resins, white enamel paints were prepared and their physical properties, anti-corrosion, and weather-resistance were examined. These were compared with non-yellowing polyurethane coatings and fluoro coatings. The anti-corrosion properties showed that coatings containing 10 wt% of alkoxysilane, 5 wt% of epoxysilane and fluoro coatings had superior properties. The weather-resistance of coatings was decreased with increasing alkoxysilane's content. Futhermore, the weather-resistance results showed that the acrylic coatings containing 30 wt% of alkoxysilane had better properties than fluoro coatings.

고방식성, 고내후성의 강구조물 도료를 제조하기 위해 알콕시실란 함유 아크릴수지 및 3급아민 함유 아크릴수지의 공중합체의 T(g)를 30℃를 목표로하여 합성하였다. 도료는 알콕시실란 함유 아크릴수지인 경우에는 알콕시실란의 함량을 10, 20, 30 wt%로 변화시키면서 경화제로 DBTDL을 사용하고, 3급아민 함유 아크릴수지는 경화제로 에폭시실란의 함량을 5, 10, 15 wt%로 변화시키면서 백색도료를 제조하여 도막의 물리적 특성, 방식성 및 내후성에 미치는 영향을 무황변성 우레탄수지 도료 및 불소수지 도료와 비교하였다. 방식성은 불소 도료, 알콕시실란 10 wt%및 에폭시실란 5 wt%인 도료가 양호하게 나타났고, 알콕시실란의 함량이 증가할수록 내후성이 개선되는 경향을 나타내었다. 특히알콕시실란의 함량이 30 wt%인 도료는 불소수지 도료보다도 양호한 내후성의 범주에 속하는 도료임이 확인되었다.
