Patent number: 6197105Abstract: 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: December 20, 1999Date of Patent: March 6, 2001Assignees: J. M. Huber Corporation, Sanyo Trading Company, Ltd.Inventors: Gary M. Freeman, Carl J. Marshall, Jr., Walter O. Lackey, Masao Onizawa

Patent number: 6011087Abstract: Modified mineral fillers, derived from either a coarse particle kaolin clay or a coarse particle ATH, having excellent utility in thermoset polymers as low paste viscosity fillers are disclosed. The method of treatment involves the use of specific weight ratio combinations of a silane and a long chain aliphatic alcohol. The treatment of clay can also involve the auxiliary use of a surfactant in small amounts, which is utilized to emulsify the silane and aliphatic alcohol treatment components in water either individually or as a co-emulsion blend prior to their addition to the clay. The surfactant, which is preferably a nonionic surfactant having a HLB value of 12-18, aides in uniformly treating all the clay particle surfaces with the silane/alcohol treatment combination. Coarse particle clays having general utility in the invention are those having an average Stokes equivalent particle diameter of at least 3.Type: GrantFiled: December 22, 1997Date of Patent: January 4, 2000Assignee: J.M. Huber CorporationInventors: Carl J. Marshall, Thomas J. Lynch, Gary M. Freeman

Patent number: 5840113Abstract: An improved finely divided rubber-reinforcing clay mineral composition can be produced by employing a hydrous kaolin clay surface treated with a functional silane, a methylene donor compound such as hexamethylenetetramine, and a multifunctional methylene acceptor such as resorcinol. A novel process of preparation is provided. The improved reinforcing, treated clay filler can be combined with natural or synthetic elastomer compositions which can be cured to elastomer products which have improved physical properties, such as modulus, tensile, tear, wear resistance and/or resistance to heat build-up.Type: GrantFiled: April 14, 1998Date of Patent: November 24, 1998Assignee: J.M. Huber CorporationInventors: Gary M. Freeman, Carl J. Marshall, Jr., Walter O. Lackey, Thomas J. Lynch

Patent number: 5667639Abstract: This invention involves a method of optically whitening clay minerals to transform their natural yellow tint to increased whiteness. Generally, it has been found that clay materials having low cation exchange capability can be directly reacted with very small amounts of cationic dyes, the apparent whiteness of said clay minerals being substantially increased thereby.Type: GrantFiled: October 8, 1996Date of Patent: September 16, 1997Assignee: J.M.
