在聚酯的合成过程中加入纳米硫酸钡,制备膜用聚酯开口剂母料。考察纳米硫酸钡对聚合反应的影响,对含有纳米硫酸钡的开口剂母料进行性能分析,用小试挤出流延机和拉膜机对硫酸钡开口剂母料进行铸片、制膜试验,考察成膜性能,对膜片进行性能分析。结果表明:纳米硫酸钡的加入对聚合过程无影响,用硫酸钡制备的聚酯开口剂母粒同用二氧化硅制备的开口剂母料性能指标基本相同。硫酸钡膜用聚酯开口剂母料制膜过程顺利,纳米硫酸钡作为开口剂的双向拉伸膜片的摩擦因数比二氧化硅作为开口剂的双向拉伸膜片的摩擦因数高。 相似文献

In packaging applications, blocking is always found in low‐density polyethylene (LDPE) films. Practically, such problems can be solved by incorporation of antiblocking agents, for example, silica and talc. The objective of this research was to explore the possibility of using silica from rice husk ash (RHA silica) as an antiblocking agent in LDPE film. Properties of RHA silica were compared with commercial silica, Sylo‐1. The appropriate amount of silica to be used as an antiblocking agent in LDPE film was also investigated. The results indicate that RHA silica has a smaller particle size and a higher specific surface area but a higher bulk density than those of Sylo‐1 silica. In the plastic film industry, 500–1000 ppm of silica is added in LDPE films as an antiblocking agent. It was also found that LDPE film with 2000–3000 ppm RHA silica showed similar properties to LDPE film filled with commercial silica in terms of its blocking behavior, mechanical strength, and film clarity. © 2003 Wiley Periodicals, Inc.

采用模压法研究了化学交联LPDE/EVA/CPE并用微孔鞋底料的制造方法,着重讨论了LDPE/EVA/CPE并用比,不同种类的橡胶改性剂以及发泡剂、交联剂、填充剂用量对微孔鞋底物理机械性能的影响。实验结果表明,采用国产原料CPE,当LDPE:EVA:CPE=50:30:20时,并配以超细碳酸钙20份和其他助剂,可制得性能较好的微孔鞋底材料。 相似文献
