Patent number: 6013699Abstract: An effective production method for silane-treated clays having exceptional reinforcing effects with respect to rubber, and compositions using these silane-treated clays are offered. With the silane-treated clay production method, a functional silane is predispersed or emulsified in water by means of a surfactant in order to mix the functional silane with kaolin clay and thereby uniformly surface-treat the kaolin clay with the functional silane. The surfactant should preferably be a non-ionic surfactant with an HLB value in the range of 8-18. The silane-treated clay formed by surface-treating kaolin clay by means of these functional silanes characteristically contains low residual levels of the non-ionic surfactants. The functional silanes can be either vinyl or sulfur functional silanes. The silane treated clays are useful as fillers or extenders in rubber compositions, particularly those employing silicas and/or carbon blacks.Type: GrantFiled: November 4, 1998Date of Patent: January 11, 2000Assignees: J.M. Huber Corporation, Sanyo Trading Co., Ltd.Inventors: Gary M. Freeman, Carl J. Marshall, Jr., Walter O. Lackey, Masao Onizawa
