摘要
最新研究开发的新型静密封材料主要有：填充玻璃纤维、碳纤维、青铜粉、石墨、二硫化钼及聚合物填充剂的改性聚四氟乙烯；膨胀聚四氟乙烯；用劳纶纤维、玻璃纤维、碳纤维、矿渣棉和芳砜纶纤维代替石棉的非石棉纤维复合密封材料；钛缠绕式垫片和镍铜合金缠绕式垫片。今后密封材料研究开发重点和发展趋势是：进一步研究开发非石棉密封复合材料，适合特殊场合使用的密封材料和结构以及纳米材料在静密封领域的应用。
The development of new sealing materials has been a main research subject in the field of sealing technology. The basic performances of sealing materials and components are discussed, and some new types of sealing materials and their application presented. Several opinions about the further development in this field are put forward in this article.
