The rubber-filler composite is obtained by jetting a field latex of a natural rubber in a form of a high-speed flow having a flow rate of 500 m/sec or more into a mixing chamber while supplying a filler slurry containing a filler to the mixing chamber, thereby separating and removing protein in the field latex from a rubber component and at the same time, mixing the field latex and the filler slurry. | 04-02-2009 |
| 20100022684 | Processes for making silane, hydrophobated silica, silica masterbatch and rubber products - The present invention provides a process for making silica-filled rubber masterbatch using silica hydrophobated with a trimethoxy silane coupling agent that is soluble in an alcohol-water solution containing at least about 70 wt % water. One embodiment uses a mixture of trimethoxy silanes, one or more of which react with rubber to bond the silica to the rubber, and one or more of which do not react with rubber, but do hydrophobate the silica. Hydrophobated silica is mixed with latex polymer and incorporated into rubber during coagulation of the latex, which is preferably coagulated with calcium chloride. The present invention further provides a process for making the trimethoxy silane coupling agents. Preferred trimethoxy silane coupling agents include bis-(3-trimethoxysilylpropyl)-disulfide and bis-(3-trimethoxysilylpropyl)-tetrasulfide. Rubber products, particularly tires, compounded with the inventive silica masterbatch can be processed for a long time before scorching because the silica masterbatch provides a long scorch time. | 01-28-2010 |
| 20110269872 | PREPARING METHOD OF POLYMER NANO-COMPOSITES - Provided is a method for preparing a polymer nano-composite, more particularly, an economical method for preparing a polymer nano-composite with improved properties via a single process of organic treatment of a layered clay mineral and dispersion in a rubber latex material at a pH where both the rubber latex material and the layered clay mineral are stabilized. The provided method for preparing a polymer nano-composite allows effective dispersion without using an organic modification process for improving dispersibility of the layered clay mineral in resin.
