• Enhanced Hydrolytic Stability of Siliceous Surfaces Modified with Pendant Dipodal Silanes
  作者：Barry Arkles、Youlin Pan、Gerald L. Larson、Mani Singh

  DOI：10.1002/chem.201402757

  日期：2014.7.21

  The stability of surfaces in aqueous environments prepared from dipodal silanes with hydrophobic alkyl functionality is compared to the stability of similar surfaces prepared from the conventional silanes. In strongly acidic and brine environments, surfaces modified with dipodal silanes demonstrate markedly improved resistance to hydrolysis compared to surfaces prepared from conventional silanes.

  双足硅烷具有两个可以共价键合到表面的硅原子。与通常用于表面改性的传统硅烷相比，它们在保持表面涂层、粘合剂底漆和复合材料在水性环境中的完整性方面具有明显的优势。引入了新的非功能性和功能性双足硅烷，其结构包含“侧链”而非“桥连”有机官能团。将由具有疏水性烷基官能团的双足硅烷制备的表面在水性环境中的稳定性与由常规硅烷制备的类似表面的稳定性进行比较。在强酸性和盐水环境中，与由传统硅烷制备的表面相比，用双足硅烷改性的表面显示出显着提高的耐水解性。悬垂双足硅烷比桥连双足硅烷表现出更高的稳定性。通过二硅氧烷键的水解形成硅烷醇物质的表观平衡常数被确定为K c =[SiOH] 2 /[Si-O-Si][H 2 O]=6±1×10 -5有助于理解双足硅烷改性表面的水解稳定性增强。

• Tire tread composition

  It has been unexpectedly determined that isoprene-butadiene rubber having a high glass transition temperature within the range of -40°C to -25°C (high Tg IBR) can be loaded with silica as a filler and utilized in manufacturing tire treads that have outstanding performance characteristics. For instance, such tire treads offer lower hysteresis at high temperatures (improved rolling resistance) and higher hysteresis at low temperatures (improved wet traction characteristics). By utilizing high Tg IBR in tire tread compounds, the maximum benefits of silica compounding can be realized without the need for solution or emulsion styrene-butadiene rubber (SBR) in the tread rubber formulations. The tire tread rubber formulations of this invention will normally contain 20 phr (parts per 100 parts of rubber) to 100 phr of the high Tg IBR. In other words, the tread rubber will normally contain at least 20 phr of the high Tg IBR and can contain up to 100 phr of the high Tg IBR. The tread compound will also contain 40 phr to 150 phr of a filler with the proviso that at least 20 phr of silica is included in the filler. The tire tread compound will also contain a silica coupling agent. This invention more specifically discloses a tire tread rubber composition which is comprised of (1) at least 20 phr of an isoprene-butadiene rubber having a glass transition temperature which is within the range of -40°C to -25°C, (2) 40 phr to 150 phr of a filler, with the proviso that the filler contains at least 20 phr of silica, and (3) a silica coupling agent.

  人们意外地发现，在-40°C 至 -25°C（高 Tg IBR）范围内具有高玻璃化转变温度的异戊二烯-丁二烯橡胶可以添加白炭黑作为填料，并用于制造具有出色性能特征的轮胎胎面。例如，这种轮胎胎面在高温下具有较低的滞后性（改善了滚动阻力），在低温下具有较高的滞后性（改善了湿地牵引特性）。通过在轮胎胎面胶配方中使用高 Tg IBR，可实现白炭黑复合材料的最大优势，而无需在胎面胶配方中使用溶液或乳液丁苯橡胶（SBR）。本发明的轮胎胎面橡胶配方通常含有 20 phr（每 100 份橡胶的含量）至 100 phr 的高 Tg IBR。换句话说，胎面橡胶通常至少含有 20 phr 的高 Tg IBR，最高可含有 100 phr 的高 Tg IBR。胎面胶还将含有 40 phr 至 150 phr 的填料，但填料中至少含有 20 phr 的二氧化硅。轮胎胎面复合物还将含有二氧化硅偶联剂。本发明更具体地公开了一种轮胎胎面橡胶组合物，该组合物由以下成分组成：(1) 至少 20 phr 的异戊二烯-丁二烯橡胶，其玻璃化转变温度在 -40°C 至 -25°C 范围内；(2) 40 phr 至 150 phr 的填料，但填料中至少含有 20 phr 的白炭黑；(3) 白炭黑偶联剂。
