    • The present invention relates to a process for making a polymer masterbatch with silica nanoparticles highly uniformly dispersed therein by using a stable aqueous emulsion of compatibilized silica nanoparticles, the sizes of which are mechanically reduced to nanoscales. Adequate reduction of the silica particles to nanoscales is essential for the formation of a desired emulsion of high stability. The said emulsion of compatibilized silica nanoparticle can be easily mixed under mild conditions with a polymer in latex form, which can be high purity natural rubber, synthetic rubber and / or a blend thereof. The bifunctional organosilane coupling agent bonded-Silica nanoparticles are subsequently incorporated into the rubber polymer network during coagulation with formic acid. The inventive rubber-silica masterbatch thus obtained is useful for manufacturing rubber and other polymer composite products.
    • 本发明涉及通过使用相容的二氧化硅纳米粒子的稳定的水性乳液,其尺寸被机械还原成纳米尺寸,制备具有高度均匀分散在其中的二氧化硅纳米粒子的聚合物母料的方法。 将二氧化硅颗粒充分还原成纳米尺寸对于形成具有高稳定性的所需乳液是必需的。 所述相容的二氧化硅纳米颗粒的乳液可以在温和条件下与胶乳形式的聚合物容易地混合,其可以是高纯天然橡胶,合成橡胶和/或其混合物。 随后与甲酸凝结,双功能有机硅烷偶联剂粘合二氧化硅纳米粒子随后被并入橡胶聚合物网络中。 由此获得的本发明的橡胶二氧化硅母料可用于制造橡胶和其它聚合物复合材料产品。

    • The invention relates to the use of nanocarbon (carbon nanotubes and/or carbon nano fibers) in the preparation of reinforced natural rubber. It is an object of the invention to provide a simple way to disperse nanocarbon in rubber so as to obtain good physical and mechanical properties, such as hardness, modulus and/or tensile strength. In order to achieve these objects, the invention provides a natural rubber composition comprising 5 parts per hundred of rubber (pphr) or less of nanocarbon, wherein the nanocarbon has not been subjected to an acid treatment before incorporation into the rubber composition. Furthermore, the invention also provides a method of making a natural rubber composition comprising nanocarbon, wherein the method comprises the following steps: (i) providing a dispersion of nanocarbon in a aqueous medium, and (ii) combining the dispersion of nanocarbon with a natural rubber latex; and wherein the nanocarbon is not subjected to an acid treatment before incorporation into the rubber composition and the natural rubber composition comprises 5 pphr or less of nanocarbon.
