20080257218 | Light Weight Additive, Method of Making and Uses Thereof - Low density additives and methods of making said additives for composite materials are provided. The low density additives have at least a partial or complete water repellant property that reduces moisture migration, absorption, and retention within a composite material in which it is incorporated into. Active sites are engineered onto the surface of the low density additives to enhance bonding of the additives within a composite matrix. Reduced water movement and enhanced bonding lead to an increased strength and durability performance for a composite material comprising such additives. Composite materials incorporating one or more engineered low density additives as also provided, such composite materials having enhanced strength and durability. Such composite materials may be made from a Hatschek process. The composite materials may be further used as interior and exterior building products. | 10-23-2008 |
20080289540 | Procedure for the preparation of a thermal, flexible and light coating paint - The invention involves a procedure in which by the combination of certain components, a thermal, flexible and light coating paint is obtained. This paint offers insulation properties with a low film thickness. This coating paint offers better insulation properties than other insulators with a higher thickness while not requiring any additional protection. These properties are due to the internal structure of the coating paint in which internal caverns are formed by the reaction of ramified chain polymers, addition of materials, and a balance of certain elements. These characteristics are impossible to get in traditional coating paints. | 11-27-2008 |
20090158962 | BINDER ADMIXTURE, KAOLIN PRODUCT AND THEIR MANUFACTURE - A binder mix containing a hydraulic binding agent and an admixture mixed therewith, a process for preparing a hydraulically hardened binder mass, a calcinated kaolin product and a process for preparing the same. A paste-like composition is formed from the hydraulically hardening binding agent, a pozzolanically reacting admixture and water, which, when so desired, contains stone aggregate or similar filler, the paste-like composition is worked and the worked composition is allowed to harden to form the binder mass. The admixture comprises spherical, porous metakaolin agglomerates, the size of which is 2-200 microns and which have an open pore structure. The invention can be used to improve the manufacturing methods of cast concrete products and shorten the manufacturing times, and to provide concrete with better mechanical and chemical properties, as well as improve the fire and frost resistance of concrete. | 06-25-2009 |
20090255441 | Starch-Based Filler and Coating Pigment Composition for Fibre Webs and Method for the Manufacture Thereof - A material which is suitable as filler or coating pigment for a fibrous web and a method for manufacturing thereof. According to the method, a feed comprising organic polymer material is cooled to at least approximately −50° C., after which it is refined in a jet refiner to a desired particle size. The present invention generates uniform pigment particles which comprise, for instance, starch esters, and which particles have a porous surface structure, in which case they are suitable for instance as coating pigments and fillers for offset and ink-jet papers. | 10-15-2009 |

20100107931 | MINERAL ORE EXPANSION USING MICROWAVE ENERGY - Methods and systems for expanding mineral ore, including perlite, are disclosed. Microwave energy is generated and applied to at least one gas. The energized gas then contacts particles of at least one mineral ore, wherein the transfer of energy softens the particles and boils the water contained therein, thereby at least partially expanding the particles. | 05-06-2010 |
20110277666 | Use of self-assembled nanoporous glass colloids for prolongation of plasticity of polymeric materials - This invention describes the encapsulation of and self-assembly of meso (nano) porous silica particles from inorganic an inexpensive silica precursor, sodium silicate. The particles have a well defined shape, high surface area, and high uniformity of the pore size, the properties that are typically found for high quality mesoporous material synthesized from organic silica precursors.

20140020602 | Processed mineral additive for reducing concrete permeability and increasing strength - A concrete additive includes expanded perlite with a volume weighted mean particle size of approximately 10-100 μm. The perlite further includes at least one additional component to improve workability and compensate for the natural tendency of expanded perlite to absorb water from the concrete mix. The additional component can include: water; a superplasticizer such as polycarboxylates, naphthalene sulfonate, and melamine sulfonate; or a hydrophobic compound such as salts of fatty acids, fatty acids, silanes, and siloxanes. The additive can be made in the form of a flowable powder or a flowable slurry. Concrete containing this additive displays superior properties to conventional concrete, including extremely high thermal resistance and high strength, low chloride ion permeability, and good early strength. The expanded perlite is a readily available raw material and the finished concrete is extremely cost effective for applications where a high strength structural concrete must withstand high temperatures. | 01-23-2014 |
20140060386 | METHOD FOR PRODUCING A POROUS PARTICLE COMPOSITE FOR AN ELECTRICAL INSULATING PAPER - A method is provided for producing an electrical insulation paper having a particle composite. The method involves mixing a dispersion of particles in platelet form, a carrier fluid and a functionalizing agent which is distributed in the carrier fluid and has a proportion by mass in the dispersion corresponding to a predetermined mass ratio based on the proportion by mass of the particles. The dispersion is sedimented, such that the particles in platelet form are arranged in essentially plane-parallel layers in the sediment. The carrier fluid is removed from the sediment. Energy is introduced into the sediment to overcome the activation energy of that chemical reaction of the functionalizing agent with the particles which forms the particle composite from the sediment with coupling of the particles via the functionalizing agent. The mass ratio is predetermined such that the particle composite has a porous structure. The insulation paper is thereby produced. | 03-06-2014 |

The dispersion generated can be used, among others, as pigment or filler for ink-jet paper. | 05-26-2016 |
