1.1 本试验方法用于流变测定二氧化硅填充化合物中的硅烷化程度。硅烷化是一种与用有机硅烷覆盖二氧化硅表面有关的化学反应，以更好地将二氧化硅掺入橡胶中。双功能硅烷可以在二氧化硅和橡胶之间提供偶联，以增强橡胶增强。 1.2 单位- 以国际单位制表示的数值应视为标准。本标准不包括其他计量单位。 1.3 本标准并非旨在解决与其使用相关的所有安全问题（如有）。 本标准的用户有责任在使用前制定适当的安全、健康和环境实践，并确定监管限制的适用性。 1.4 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《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认标准化原则制定的。 ====意义和用途====== 5.1 该测试方法基于佩恩效应。使用无转子振荡剪切流变仪测量应变软化，以量化二氧化硅填充橡胶中的硅烷化程度，是评估化合物填充网络形成的合理方法。 5.2 本试验基于硅烷抑制二氧化硅填料网络形成（絮凝）的能力，并将此行为与合成的硅烷化程度相关联。 5.3 可以根据硅烷化/性能相关性选择最佳混合条件，以获得所需的化合物性能。 通过本试验方法量化的硅烷化程度用于控制和预测化合物性质，而不管混合方案或设备，或两者。

1.1 This test method is used to rheologically determine the degree of silanization in a silica filled compound. Silanization is the chemical reaction related to covering the silica surface with organosilanes for a better incorporation of silica into rubber. Bifunctional silanes can provide coupling between silica and rubber for enhanced rubber reinforcement. 1.2 Units— The values stated in SI units are to be regarded as the standard. No other units of measurement are included in this standard. 1.3 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. 1.4 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 based on the Payne Effect. It is a reasonable approach to evaluate the compound’s filler-network formation to quantify the degree of silanization in a silica-filled rubber using a rotorless oscillating shear rheometer for the measurement of the strain softening. 5.2 This test is based on silane’s capability to suppress silica filler network formation (flocculation) and correlates this behavior to the resultant degree of silanization. 5.3 The optimal mixing conditions can be selected based on the silanization/property correlations to give desired compound properties. The degree of silanization quantified by this test method is used for controlling and predicting compound properties regardless of the mixing scheme or equipment, or both.
