摘要
LMU竖向缓冲件(以下简称VE)对橡胶材料有着严苛的性能要求,产品压缩比高达30%以上,且对耐老化返原和耐撕裂性能也有较高要求。国产化的LMU缓冲件示范应用于文昌9-2/9-3CEP组块浮托安装项目,其中VE的压缩比达45%、制品厚度大、硫化时间长和特殊的设计结构等因素要求胶料具有100%定伸低、拉伸强度高、撕裂强度高、耐返原性能好、压缩永久变形低等特点,本文介绍了胶料进行的一些配方优化方案。
LMU vertical buffer（hereinafter referred to as VE） has strict performance requirements for rubber materials. The compression ratio of products is as high as more than 30%, and it also has high requirements for anti-aging reversion and tear resistance. The domestically produced LMU buffer is demonstration applied in the floating support installation project of Wenchang 9-2/9-3 CEP block. Among them, factors such as the compression ratio of VE reaches 45%, the thickness of products is large, the vulcanization time is long and the special design structure require that the rubber compound has the characteristics of 100% low elongation, high tensile strength, high tear strength, good reversion resistance, low compression set. This paper introduces some formula optimization schemes of the rubber compound.
