摘　　要：针对PPS板材黏性介质温热成形过程中黏性介质的导热性能较低、加热准备时间长等问题,提出在黏性介质中填充与黏性介质密度相近、导热性能更好的镁颗粒。通过填充镁颗粒在黏性介质中的沉降试验和不同填充质量分数条件下黏性介质导热系数测量试验,得到了填充镁颗粒在黏性介质中的沉降及对导热系数的影响规律。同时,通过填充镁颗粒黏性介质的PPS板材温热胀形试验,得到了填充不同镁颗粒对黏性介质加热准备时间及PPS胀形质量的影响。研究结果表明,填充质量分数为40%镁颗粒,不仅可以提高黏性介质导热性能,缩短加热准备时间,同时对黏性性能及胀形试件质量影响较小。In order to solve the problems of Polyphenylene Sulfide(PPS)sheet warm forming with viscous medium,such as low thermal conductivity and long heating preparation time,magnesium particles with similar density and better thermal conductivity were filled in viscous medium.Through the sedimentation test of magnesium particles in viscous medium and the measurement test of thermal conductivity of viscous medium under different filling mass fraction,the sedimentation of magnesium particles in viscous medium and the influence rule on thermal conductivity are obtained.At the same time,the effect of different magnesium particles on the heating preparation time and the quality of PPS bulging is obtained by the warm bulging test of PPS sheet filled with magnesium particles in viscous medium.The results show that 40%magnesium particles not only can improve the thermal conductivity of viscous medium and shorten the heating preparation time,but also have little effect on the viscous properties and the quality of bulged specimens.
