Description

橡胶圈
技术领域
本发明涉及密封圈制造技术领域，尤其是一种用于密封的大型橡胶圈。
背景技术
橡胶通常可以分为合成橡胶和天然橡胶两类，两者皆有相当多的应用及产品，例如轮胎、垫圈等。其中，橡胶圈多用作密封或者缓冲领域，特别是0型橡胶圈在气压或者液压密封场合应用广泛。有一种在高温静密封状态下使用的大型的0型橡胶圈；由于0型圈受到密封处的长时间高温的作用，容易出现老化变形导致降低使用寿命的问题。
发明内容
本发明所要解决的技术问题是提供一种橡胶圈，以解决现有在高温静密封状态下使用的0型橡胶圈使用寿命的问题。
本发明解决技术问题所采用的技术方案为:这种橡胶圈包括橡胶圈本体，其特征在于:所述橡胶圈本体包括内橡胶复合层、外橡胶复合层和设在所述外橡胶复合层与所述内橡胶复合层之间的中间骨架层；所述中间骨架层具有设置在环形橡胶圈内的金属网筒，所述环形橡胶圈包括下列重量 份的材料:丁二稀: 45份〜55份，丙烯腈21份〜24份，防老剂8份〜11份；所述外橡胶复合层包括下列重量份的材料:聚氯乙烯树脂80份〜90份，有机硅橡胶20 份〜50份，硝酸镁10份〜20份，硝酸锌10份〜20份重量份，纳米氧化钓3份〜5份，石蜡的5份 〜15份；
所述内橡胶复合层为涤纶包芯线。
上述橡胶圈技术方案中，更具体的技术方案还可以是：所述外橡胶复合层的厚度为0.9毫米〜1.2毫米，所述中间骨架层的厚度为2.5毫米〜3毫米。
由于采用了上述技术方案，本发明与现有技术相比具有如下有益效果：1、由于设置了内、外橡胶复合层、和位于两者之间的中间骨架层，且中间骨架层设有金属网筒，增加了该橡胶圈的刚性; 2、外橡胶复合层采用耐高温材料，内橡胶复合层采用不易变形的涤纶包芯线延长了本橡胶圈的使用寿命。
