초록

본 연구에서는 차선도료로 MMA (methyl metacrylate) 수지계 열경화성 수지를 선정하여 차선의 내구성능과 재귀반사성능을 개선할 수 있는 최적의 열경화성 차선도료를 설계하고자 하였다. 특히 현장 적용성을 향상시키기 위하여 차선도료의 경화시간을 8 min으로 단축하기 위해 주재의 구성요소를 설계하였다. 실험 결과 MMA 모노머(Tg = 105 ℃) 15.6 wt%에 PMMA (ploymethyl metacrylate, MW = 70,000, Tg = 60 ℃) 6.0 wt%와 TMPTA (trimethylolpropane triacrylate, MW = 338, Tg = 27 ℃) 1.2 wt%를 배합한 TSRM-6가 부착강도 등 도료물성이 우수하여 최적 배합비율로 결정하였다. 열경화성 차선도료의 도장조건은 분사 전 반드시 균일한 혼합이 이루어져야 하며 최적 설계된 TSRM-6에 우천용 유리알을 사용한 경우 마모시험 횟수 20만 회에서 야간재귀반사성능계수는 431 mcd.m-2.lux-1 (건조 조건), 354 mcd.m-2 .lux-1 (젖은 조건), 172 mcd.m-2.lux-1 (비오는 조건)으로 우수한 성능을 나타내었다.

Several attempts to design the best-available thermosetting road markings by using MMA to improve the durability and retroreflectivity are presented in this paper. In order to improve field applicability, the components of main materials were designed by means of reducing the hardening time lower than eight minutes. The optimum mixing ratio of thermosetting road marking was TSRM-6 composed of 15.6 wt% of MMA monomer (Tg = 105 ℃), 6.0 wt% of PMMA (MW = 70,000, Tg = 60 ℃) and 1.2 wt% of TMPTA (MW = 338, Tg = 27 ℃). Also the homogeneous mixing of all components was necessary. The use of ceramic glass beads with an optimized TSRM-6 exhibited excellent performance by achieving retroreflectivity coefficients of 431, 354 and 172 mcd.m-2.lux-1 for dry, wet and rainy test condition, respectively at two hundred thousand cycles.
