High Impact Polystyrene의 難燃化와 그 熱安定性에 關한 硏究

Abstract

High Impact Polystyerne(HIPS)의 難燃化를 爲하여 세 種類의 Bronine 系 難燃劑를 ASTM-D 635 에 依해 試驗하여 難燃劑 單獨으로 쓸 때의 要求量을 求하였고, 相乘效果劑 Sb₂O₃를 添加했을 때의 難燃劑/Sb₂O₃ 比率을 決定하였다. 또 HIPS의 難燃化에 따르는 熱安定性 實驗을 하여 各 難燃劑에 對해서 가장 좋은 安定劑의 種類 및 濃度를 求하고, 安定劑 등 難燃劑 以外의 成分이 混合될 때에 그것들이 難燃性에 미치는 影響을 檢討하였다.

Three kinds of Bromine type Fire-retardants were tested in the High Impact Polystyrene(HIPS) by ASTM-D-635. The amount of each fire-retardant was given when the fire-retardant was used only, and used with the synergist antimony trimony trioxide.

And the thermal stability of flame-retardant HIPS was tested when various stabilizers were added. The effect of additives other than fire-retardant and synergist on the flammability of flame-retardant HIPS was discussed.
