Abstract:
Disclosed are flocced mineral materials which may be utilized to prepare high temperature resistant, water resistant articles. These materials are prepared by utilizing, as a starting material, a gellable layered swelled silicate that has an average charge per structural unit that ranges from about -0.4 to -1 and which contains interstitial cations which promote swelling with a source of at least one species of multiamine derived cations.
Abstract:
Chemically prepared mica and vermiculite materials are described along with the method for preparing them. The mica and vermiculite has dimethylacetamide-lithium chelation complexes at interlayer cationic sites. These materials can be made into suspensions and flocculated.

Abstract:
An aqueous suspension of sheet silicate and the method of making the same are disclosed. The suspension is produced by treating crystals of 2:1 layer sheet silicates with a solution containing a water soluble salt of a cation of a secondary, tertiary or quaternary alkyl ammonium compound and thereafter dispersing the vermiculite crystals.
Abstract:
Two:One layered silicate flocs with homogeneously intermixed polymers and a method for the compositions's preparation is described. Preferred embodiment include co-flocculated homogeneously intermixed polymer and 2:1 layered silicate. The materials are prepared by contacting a co-dispersion of polymer and silicate with a cationic flocculant.
Abstract:
Disclosed are compositions of flocced mineral materials combined with fibers and/or binders. These compositions may be utilized to prepare high temperature resistant, water resistant articles. These materials are prepared by utilizing, as a starting material, a gellable layered swelled silicate that has an average charge per structural unit that ranges from about -0.5 to -1 and which contains interstitial cations which promote swelling with a source of at least one species of an exchange cation that is derived from guanidine or compounds closely related thereto.
Abstract:
Disclosed are fire-resistant paper-like materials. These materials are prepared by embedding a fabric in a layered inorganic silicate matrix that has an average charge per structural unit that ranges from about -0.4 to -1 and which contains at least some interstitial cations that are selected from the group consisting of guanidine and multiamine derived cations.
Abstract:
A method for continuous dyeing of pile fabric using a Kusters dye applicator is disclosed. The method concerns the use of a dye solution comprising at least two dyestuffs, the dyestuffs being selected to have approximately equal strike rates, and a sufficient amount of a thickening agent to provide a dye solution-viscosity of from about 300 to about 1000 centipoise (Brookfield Viscometer). The resulting dyed carpet exhibits excellent shade uniformity in the across machine direction.
Abstract:
Sheets and laminated composites are described which are prepared with epoxy and flocculated vermiculite and mica dispersions. Processes and procedures are also described to obtain film and sheet materials from the flocculated silicate and epoxy dispersions.
