摘要： A method for preparing a time-stable, low viscosity, pumpable high solids aqueous bentonite slurry which has good application properties upon dilution and use. An aqueous solution of at least first and second salt components is prepared in which there is dispersed at least 8% by weight of the resultant slurry of a powdered bentonite. The first salt component is selected to give if used alone an acceptably low viscosity to the slurry at said high solids and at least good application properties upon the dilution and use. The second salt component is selected to act in combination with the first salt component to substantially further decrease the acceptably low viscosity at a specified high solids content or to enable increase of the solids content while maintaining the acceptably low viscosity, while not substantially impairing the application properties. The high solids pumpable slurry product is also claimed.

摘要： An improvement is disclosed for use in the process wherein an organophilic clay is manufactured by reacting a sodium smectite-type clay with a higher alkyl-containing quaternary ammonium compound. According to the improvement of the invention, the gelling properties of the resulting organoclay are enhanced, by subjecting the clay to high energy pugmilling prior to the reaction thereof with the ammonium compound. This is preferably effected by passing the clay at 25 to 40 weight percent moisture content, through a pugmill which imparts at least 20 HP/hrs/ton of energy to the clay, after which the clay is subjected to the prior art processing.

摘要： In the method for preparing a nanocomposite by intercalating a smectite clay with a quaternary ammonium ion, and exfoliating the intercalated clay into a polymer matrix; an improvement is disclosed which augments exfoliation. The smectite clay is edge treated with negatively charged organic molecules prior to the exfoliation. For these purposes a high charge density anionic polymer such as a polyacrylate may be used.

摘要： Unusually high loading levels of smectite minerals are found to provide excellent pigment spacing in aqueous-based coatings, as will enable desired improved hiding, thereby extending the pigment. The level of smectite used in accordance with the invention is sufficiently high that the high gelling efficiency smectites previously used as thixotropes would be inappropriate, and would yield viscosities so high as to render the aqueous coating composition lacking in desired flowability properties. Thus in accordance with the present invention, there is mixed with the aqueous carrier and pigment at least 0.5% by weight of the total composition, of a particulate water swellable smectite which has a gelling efficiency such as to display a 20 rpm Brookfield viscosity of less than 900 cps when subjected to the standard gelling test herein, with the amount of the smectite in the composition not exceeding that which would raise the viscosity of the composition above 110 Krebs Units (KU).

摘要： A smectite clay is provided as an elevated solids aqueous slurry e.g. up to 50% solids, which is composed of the smectite clay slurried or dispersed in water containing an effective concentration of a monovalent salt. When such a salt is present in the clay slurry, the clay does not swell appreciably, is essentially inactive, and the slurry can be shipped and stored without creating a gelling problem. When this slurry is diluted with fresh water at the point of application to make it of the desired solids content for use, the smectite clay is activated and exhibits the desired properties, such as viscosity, retention, etc.
