摘　　要：制备了聚丙烯(PP)/海泡石复合材料,考察了海泡石对复合材料熔融性能、结晶性能、力学性能及热变形温度的影响。结果表明:海泡石的加入提高了PP的结晶温度,降低了PP的熔点和结晶度;海泡石对PP的拉伸强度和冲击强度影响不大;海泡石的加入明显提高了PP的热变形温度。Polypropylene （PP）/sepiolite composite was prepared, the effects of sepiolite on crystallization property, melting property, mechanical property and heat distortion temperature of the composite were investigated. The results show that： the addition of sepiolite increases the crystallization temperature of the composite, decreases the melting point and crystallinity of the composite; sepiolite has little effect on tensile strength and impact strength of the composite; the heat distortion temperature of PP/sepiolite composite is obviously higher than that of neat PP.
