1.1 本试验方法包括使用密封腔无转子振荡剪切流变仪，测量在橡胶混合过程中施加到含有大量胶体填料（如二氧化硅或炭黑，或两者）的未硫化橡胶混合物时，正弦应变上升的软化效应。这些应变软化特性与混合条件、橡胶化合物的组成、填料的胶粒（Payne效应）特性以及在某些情况下，在混合过程中有机硅烷与沉淀的水合二氧化硅之间的反应程度有关。该程序通常适用于橡胶反应性混合程序。 1.2 本标准并不旨在解决与其使用相关的所有安全问题（如有）。本标准的使用者有责任在使用前建立适当的安全、健康和环境实践，并确定监管限制的适用性。 1.3 本国际标准是根据世界贸易组织技术性贸易壁垒（TBT）委员会发布的《国际标准、指南和建议制定原则决定》中确立的国际公认标准化原则制定的。 =====意义和用途====== 5.1 该试验方法用于通过应变幅度扫描的应变软化效应（佩恩效应）测量粘弹性特性。 5.2 对于未固化状态，时间调节和应变幅度应变扫描可能与混合过程中的胶态二氧化硅颗粒或炭黑脱团聚有关。G’储能模量的佩恩效应曲线也可以是橡胶烃介质中这些填料的负载水平和颗粒尺寸的函数。此外，使用二氧化硅和有机硅烷添加剂，这种G’应变软化效应可以确定是否通过反应性混合实现了目标二氧化硅和有机硅烷之间的给定硅烷化反应。如果在混合过程中没有实现硅烷化反应，则应变扫描的最大G’储存模量将不会降低，二氧化硅颗粒对其他二氧化硅颗粒的吸引力仍然很高，从而留下更致密的填料网络。

1.1 This test method covers the use of a sealed cavity rotorless oscillating shear rheometer for the measurement of the softening effects of rising sinusoidal strain when applied to an unvulcanized rubber compound containing significant amounts of colloidal fillers (such as silica or carbon black, or both) from a rubber mixing procedure. These strain softening properties relate to mixing conditions, the composition of the rubber compound, colloidal particle (Payne Effect) characteristics of the fillers, and in some cases the degree of reaction between an organosilane and precipitated, hydrated silica during mixing. This procedure is being commonly applied to rubber reactive mixing procedures. 1.2 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.3 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee. ====== Significance And Use ====== 5.1 This test method is used to measure viscoelastic properties through the strain softening effects of a strain amplitude sweep (the Payne Effect). 5.2 For the uncured state, the time conditioning and strain amplitude strain sweeps can relate to colloidal silica particle or carbon black deagglomeration from the mixing process. The profile of this Payne Effect from G’ storage modulus can also be a function of loading levels and particle size of these fillers in the rubber hydrocarbon medium. In addition, with silica and an organosilane additive, this G’ strain softening effect can determine if a given silanization reaction between a subject silica and an organosilane was achieved through reactive mixing. If the silanization reaction during the mixing was not achieved, the maximum G’ storage modulus from the strain sweep will not be lowered and the silica particle attraction to other silica particles will still be high resulting in a more dense filler network that remains.
