摘要

本研究為進行紡絲月耐隆材料於交聯改質與無鹵阻燃劑之添加，進行一系列熱性質與然燒特性之評估。本研究探用雙螺桿熔融混練法製備難融滴阻燃交聯耐隆粒，以TGA、DSC 交LOI進行相關性質分析。結果顯示添加交聯劑後不影響耐隆材料本身的玻璃轉移溫度（Tg）與熔點（Tm），但因交聯作用使材料在燃燒的過程中，有助於提升焦炭殘餘率為3.9%，故交聯作用有助於高分子於燃燒中產生碳化層，而達到無融滴阻燃之效果，其最佳LOI值為28。

This paper was focused on the thermal degradation and combustion behavior of crosslink polyamide 6. The flame retarded crosslink polyamide 6 masterbatches were prepared by adding halogen free flame retardant and crosslinking agent in thermal twin screw extruder system. The evaluation of thermal gravity analysis (TGA), differential scanning calorimeter (DSC) and limiting oxygen index (LOl) for flame retarded crosslink polyamide 6 were also studied. The results exhibited that the char forming ratio was increased as increasing the crosslink agent. The forming of char layer for polyamide 6 upon the combustion could hinder the fire spreading. The high crosslink structure of polyamide 6 is benefit to the polyamide 6 in flame retard application.
