Description

一种复合材料密封圈，属于机械工程密封件。
密封的功用是阻止泄漏。起密封作用的零部件称为密封件。现有的密封件，例如泵轴密封件，有的密封性能欠佳，有的使用寿命欠长，有的安装调整条件苛刻。
本实用新型之目的在于提供一种密封性好、寿命长、使用方便的耐高温耐腐蚀的新型密封件。
本实用新型是一种用复合材料制成的环形密封圈。
环形密封圈的轴向截面可以是方形的，也可以是V形、O型或其他形状。
密封圈可以制成多种规格，以满足机械工程密封的需要。
密封圈的材料是复合材料。复合材料是把两种以上不同性质的材料经过复合而制成的一种新材料。它可以克服单一材料的某些弱点，发挥其各组分材料的优点，提高材料的综合性能。
复合材料的基材是石墨。增强材料是耐热耐蚀的聚四氟乙烯、抗压耐磨的二硫化钼、有很好耐热性和机械性能的聚酰亚胺、耐磨并且有高抗蚀性润滑性的青铜粉以及炭黑。
密封圈的制造方法是：先将石墨基材处理成粉状，加上一定配比的粉状增强材料，充分搅拌混合，然后常温下模压成型，再在380℃～400℃高温下烧结。冷却至常温后再精压一次即可。模压及精压的压力视密封圈的规格而定。在复合材料的成型过程中，基材经过一系列物理的、化学的复杂变化过程，与增强材料复合成具有一定形状和性质的整体。
复合材料密封圈耐温≤350℃，寿命≥5000小时，能耐不同浓度的酸、碱、盐等腐蚀性介质，可用于动密封或静密封。使用时，只要将其装入转轴或者其他需要密封的地方就可以了。
由于复合材料密封圈具有密封性好、耐高温耐腐蚀、寿命长、使用方便等特点，因此可以广泛应用于机械、化工等行业，尤其适宜于泵类产品的密封。
附图所示的实施例，是本实用新型系列产品中的一种。密封圈的内径42mm，外径62mm，厚度10mm，轴向截面为方形，用于泵的密封。

Claims (3)

1、一种复合材料密封圈，其特征在于这是一种用复合材料制成的环形密封圈。
2、按权利要求1所述的密封圈，其特征在于这种密封圈的轴向截面可以是方形的，也可以是V形、O形或其他形状。
3、按权利要求1或2所述的密封圈，其特征在于所述的复合材料以石墨为基材，聚四氟乙烯、二硫化钼、聚酰亚胺、青铜粉和炭黑为增强材料。
