Abstract

본 연구에서 중온아스팔트를 제조하기 위하여 우레탄폼 제조기술과 유화아스팔트 제조기술을 이용하여 폼아스팔트를 제조하였다. 화재에 약한 폼 물질과 아스팔트의 취약점을 보완하기 위하여 난연제를 첨가하여 난연성 폼아스팔트를 제조하였다. 폼아스팔트의 표피는 구멍이 뚫려 있었고 내부구조는 열린 셀의 모양을 하고 있었다. NCO%가 높을수록 폼의 강도와 셀의 크기는 증가하였다. 아스팔트는 폼의 강도를 증가시켰다. 하지만 난연제는 폼의 강도를 떨어뜨렸다. 사용된 3가지 난연제(멜라민, 디메틸포스포네이트, 트리토릴포스페이트) 중에서 멜라민이 가장 난연효과가 적었고 트리토릴포스페이트가 가장 효과가 크게 나타났다. This study was carried out to prepare a type of warm mix asphalt. Through urethane foam and emulsion asphalt preparation techniques a protocol of asphalt foam was made. Then three kinds of flame retardant agents were added in there to alleviate the inherent susceptability of asphalt and foam material to flame and thus flame retardant asphalt foam was made. The internal structure of form asphalt was composed of open cell. The higher the NCO% brought the larger the cell and the stronger also. Asphalt increased the strength of the foam. Among the flame retardant agents employed tritorylphosphate was the most effective.
