覆膜丁腈橡胶的耐高温润滑油特性研究

Study of High-temperature Lubricating Oil Resistance of Butadiene-acrylonitrile Rubber Covered by Fluoroplastic Film

  • 摘要: 本研究的主要目的是利用氟塑料(PTFE)薄膜的耐介质性,来提高丁腈橡胶的耐润滑油性。首先采用冷等离子体处理技术(CPT)对PTFE薄膜和丁腈橡胶混炼胶进行了表面处理,以改善两者的表面粘接性,用高温胶黏剂将PTFE薄膜粘接在丁腈橡胶表面制成覆膜丁腈橡胶。表征了丁腈橡胶和覆膜丁腈橡胶在100℃高温润滑油中的微观形貌、物理力学等性能,并分析了这些性能变化规律。结果表明:随试验时间的延长,覆膜丁腈橡胶的微观形貌变化不明显,长度、质量基本不变,压缩永久变形、拉伸强度和断裂伸长率下降幅度更低。覆膜丁腈橡胶的耐高温润滑油性较丁腈橡胶有所提高。

     

    Abstract: The main purpose of this paper is to improve the lubrication oil resistance of the butadiene-acrylonitrile rubber (NBR) by using the medium resistance of fluoroplastic (PTFE) film. To increase the surface adhesion, the surface of PTFE film and NBR compounds were firstly treated by the cold plasma technology (CPT); Then the NBR samples were covered with PTFE film by using the high temperature adhesives. The micro morphology,physical and mechanical properties of the vulcanizates of the coated NBR in high temperature lubricating oil at 100℃ were tested and analyzed. The results indicated that with the experiment time increasing, the micro morphology of coated NBR didn't change obviously, the dimension and mass kept almost unchanged; but the compression set, the tensile strength and the elongation declined slightly. As a result, the lubricating oil resistance of NBR could be improved by PTFE film. Coating NBR could improve the lubricating oil resistance of NBR.
