US Patent:

56676395, Sep 16, 1997

Filed:

Oct 8, 1996

Appl. No.:

8/727729

Inventors:

Carl J. Marshall - Macon GA
Gary M. Freeman - Macon GA

Assignee:

J.M. Huber Corporation - Edison NJ

International Classification:

D21H 2128

US Classification:

162162

Abstract:

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.

International Classification:

C09K 1500

US Classification:

Assignee:

J.M. Huber Corporation - Edison NJ

International Classification:

C09C 142

US Classification:

106487

Abstract:

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.

International Classification:

C08K 500
C04B 1410
C09C 102

US Classification:

106499

Abstract:

A mineral based coloring pigment has been developed which includes a water-soluble organic dye which has been insolubilized or "fixed" onto a mineral pigment substrate by means of a cationic or anionic chemical compound. Also, a method for producing the mineral based coloring pigment and products containing the mineral based coloring pigment have been developed.

US Classification:

523212

Abstract:

International Classification:

US Classification:

523212

Abstract:

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.
