摘要： A heat stabilized slurry of bulked kaolin pigment is prepared by mixing a small but effective amount of a water-soluble cationic material such as a cationic polyelectrolyte flocculant with a kaolin clay pigment in the presence of water. The resultant bulked clay product is dispersed to form a high solids clay-water slurry useful in making aqueous coating colors suitable for manufacturing lightweight coated publication papers or the pigment can be used as a filler for paper webs. Slurries having stable viscosity during storage at elevated temperature and improved resistance to the formation of sediment are prepared by using as the dispersant a combination of an anionic lignosulfonate and an anionic naphthalene sulfonate formaldehyde complex in combination with a polyacrylate salt.

摘要： An inorganic filler composed of a modified montmorillonite group clay mineral and having an X-ray diffraction pattern inherent to montmorillonite, an oil absorption of at least 100 ml/100 g and a Hunter whiteness of at least 80%. The modified clay mineral is produced by reacting a clay mineral of the montmorillonite group which 10 to 200% by weight based on the dry weight of the mineral, of an alkaline earth metal hydroxide in the presence of water, and reacting the reaction product with a salt of a metal of Group IIb, III or IV of the periodic table containing an acid radical which gives a soluble alkaline earth metal salt upon reaction. The inorganic filler is especially suitable for use in lightweight paper.

摘要： A corrosion inhibitor comprises particles of an inorganic oxide having cations of yttrium or cations of one or more metals of the lanthanide group chemically bound to the particles by ion-exchange. The cations are released by ion-exchange with other cations and not by the water solubility of the corrosion inhibitor.The corrosion inhibiting particles may be prepared by contacting particles of the inorganic oxide with an aqueous solution containing the required cations. Alternatively, the particles of the inorganic oxide may be contacted with an aqueous solution of an alkali metal so that alkali metal ions are exchanged onto the surface of the oxide and then contacting the alkali metal exchanged oxide with a solution of the required cations so that the required cations replace the alkali metal cations.The corrosion inhibiting particles may be incorporated into protective coatings e.g. paints based on epoxy resins, alkyd resins, vinyl resins or chlorinated rubbers in amounts up to 80% wt. based on the dry film weight of the coating.

摘要： Several organic acid reactive comminuted minerals, which are generally used as fillers for plastics, rubber, etc., are treated with unsaturated organic acids, alone or in admixture with saturated acids, antioxidants and, alternatively, liquid agents. The surfied (surface modified) fillers thus obtained have excellent wetting and dispersion in both polar and non-polar media as exemplified by their superior packing fractions. Unsaturated acids, alone or in admixture with saturated acids, do not yield fillers stable to the effects of oxidation, both in preparation and use. It has been discovered that very low concentrations of antioxidants stabilize the surfied filler against oxidation and resulting instability. Liquid agents also have been discovered to add a new dimension to the art by cooperating with the acid surfiers (surface modifiers) to modify the interface between the filler and matrix to a greater extent than by previously available techniques. These surfied fillers are thus valuable adjuncts in formulating plastics and related compositions.

摘要： A filler for paper, card or board which has a good retention and consists of an inert core material and a hydrophilic coating, which consists of polyacrylamide having a molecular weight of 10.sup.5 to 10.sup.7 or of a mixture of this polyacrylamide with a urea-formaldehyde condensation resin. The filler is prepared by suspending the inert core material in an aqueous solution of a polyacrylamide having a molecular weight of 10.sup.5 to 10.sup.7 or in an aqueous solution of such a polyacrylamide and a urea-formaldehyde condensation resin, and drying this suspension by spray drying or in a stream of hot air. This crosslinks the initially water-soluble polymer and forms a coating, adhering to the core, which is insoluble in water but is hydrophilic and swells, and becomes tacky, in the presence of water.
