초록

나노실리카볼 입자를 합성하고 표면에 비닐기를 부여하는 합성 연구를 통해 다양한 크기로 조절이 된 유-무기하이브리드 입자인 비닐-나노실리카볼이 합성되었다. 다양한 크기의 비닐-나노실리카볼 입자를 상업적으로 적용되고 있는 아크릴-멜라민 클리어코트에 후첨시키고 경화시켰을 때, 클리어코트의 광택도 증가 및 유지 특성에 대해 연구하였다. 실리카볼 입자가 250 nm 정도인 경우 Matting effect에 의한 광택도 감소가 관측되었으나 20∼30 nm로 작아지면 광택도 유지 효과가 약 7%까지 증가하였다. 나노실리카볼 대신 상업용 친수 실리카 Aerosil 200 (Hydrophilic fumed silica, 평균입도 12 nm, Degussa)을 사용하여 비닐- fumed 실리카 화합물을 합성하여 클리어코트에 적용하면 광택도 유지효과가 약 2% 정도만 증가하였다.

Inorganic-organic hybrid material such as vinyl-nano sized silica ball was synthesized by acrylo-alkoxysilane and nano silica ball with different particle size. And then they were formulated into acrylic-melamine clearcoat. This material is fully characterized with various analytical methods and applied for strength measurement. The glossy effect, matting effect and anti-scratching properties of materials were investigated for further growth and maintenance. When the particle size of nano silica ball is 20∼30 nm, the glossy retain effect was increased by 7% compared to bare acrylic-melamine clearcoat. When a commercially available silica Aerosil 200 (Hydrophilic fumed silica, average particle size 12 nm, Degussa) react with vinyl alkoxysilane vinyl-fumed silica complex form. The vinyl-fumed silica along with clearcoat increases only 2% increase at glossy retain. Nano-scratch test results also support the glossy retain effect of vinyl nano-sized silica ball in clearcoat.
