This study is divided into two parts. The first part was fabrication of warming additive slurry. The slurry is made by adding warming powders and sodium pyrophosphate in deionized water (DI Water) solvent, then ball milled. The effects of sodium pyrophosphate on the average particle size and zeta potential of the warming powders was discussed. The second part was fabrication of polyamide 6 warming chips by using in-situ polymerization of ε-caprolactam (CPL). After open-ring reaction, polymerization, then cooled, the composite was produced. The composite was crushed, purified and dried as the chip form. The far infrared ray emission coefficient of composites was measured to determine the heat preservation ability. The best performance of warming slurry suspension for added sodium pyrophosphate for dispersant, it has the best average particle size D50 is 444.22nm at pH value is 11.79 with -48.52mV zeta potential. The suspension could be conserved more than three days. The synthesized warm-retention polyamide 6 chips with such suspension exhibits a relative viscosity value is 2.690 which could be spun. The far infrared ray emission coefficient value of obtained composite is 0.926.
本研究主要分為兩個部分:第一部分係探討將經濕式研磨後之熱感粉體與陰離子型分散劑焦磷酸鈉(sodium pyrophosphate, SPP)添加於水性溶液中,並進行其之分散性分析;第二部分為以化學合成法(chemical synthesis method),係在原位聚合法(in-situ polymerization)合成PA6(Polyamide 6, Nylon 6)過程中添加具有蓄熱保溫能力之熱感粉體,經過開環反應、聚合反應、冷卻、破碎、純化、乾燥之程序製得聚醯胺6熱感切片之試樣,最後再對其相對黏度及遠紅外線放射係數進行測試,用以評估熱感粉體的添加量對其材料性能的影響。實驗結果發現,熱感懸浮液添加焦磷酸鈉後其平均粒徑D50為444.22nm,表面電位於pH值11.79時有最佳值-48.52mV,且熱感懸浮液於第三天時才有沉降現象;聚醯胺6熱感切片之相對黏度可達2.690,遠紅外線放射係數可達0.926。
