摘要:
A process for producing heat-expandable microspheres including a thermoplastic resin shell and a blowing agent encapsulated therein. The process includes the steps of dispersing a polymerizable component and the blowing agent in an aqueous dispersion medium having a pH of 7 or less and containing a fine-particle metal compound having a mean particle size ranging from 1.0 to 10 nm, and polymerizing the polymerizable component. The amount of the fine-particle metal compound ranges from 0.15 to 20 parts by weight to 100 parts by weight of the total amount of the polymerizable component and the blowing agent. Also disclosed are heat-expandable microspheres produced by dispersing a polymerizable component and a blowing agent in an aqueous dispersion medium containing colloidal silica and polymerizing the polymerizable component. Also disclosed is a composition containing the heat-expandable microspheres and a base component, a formed product, a slurry composition for use in forming a negative electrode of a lithium-ion secondary battery and a negative electrode.

The web frame is a bonded assembly of panels and porous blanket layers, separated by an arrangement of isolated spacers. The panels and spacers are covered with a bonding means. A coating covers inner surfaces of the panels and spacers. The porous blanket is compressed and pinned between these panels, by spacers that are arranged as isolated nodes or columns The spacers have sharpened ends that penetrate the blanket and connect with the opposing panel. The web frame assembly provides thermal and sound insulation for buildings and other solid objects. These web frames are lightweight, durable, and permeable. Capillaries and passages throughout the panels and fibres of the blanket allow passage of moisture and air, thereby assisting in the management of condensation within the web frame.

A low-E housewrap having improved energy efficiency protection against air infiltration and moisture build-up in buildings. The aforementioned low-E housewrap material utilizing existing framing openings or without increasing the wall profile of a building. The present invention provides a low-E housewrap material which may be implemented on traditional 2×4 framing having R-15 mass insulation material within existing or newly constructed framing cavities. The material of the present invention also meets requirements for serving as a water resistive barrier as defined by ICC AC38.
摘要:
A composite building panel that includes a central body, substantially parallelepipedic in shape, containing an expanded polymer matrix, having opposite faces, a top surface, and a bottom surface; at least one embedded framing stud longitudinally extending across the central body between the opposite faces, having a first end embedded in the expanded polymer matrix, a second end extending away from the bottom surface of the central body, and one or more expansion holes in the embedded studs between the first end of the embedded stud and bottom surface through which the polymer matrix expands. A concrete layer can optionally cover a portion of the top surface and/or bottom surface. The building panel can be positioned perpendicular to a structural wall and/or foundation to provide a floor panel. The second end of the framing studs can be embedded in a second central body to provide an insulated concrete form.

A composite wall panel is provided. The composite wall panel comprises a first layer of molded structural material and a second layer of molded structural material. An insulating foam layer is disposed between the first and second molded structural layers. The foam layer includes a first major side in contact with the first layer of molded structural material and a second major side in contact with the second layer of molded structural material. The first and second major sides of the insulating foam layer each have at least one groove. Each groove has at least one groove shoulder. At least one connector is configured to anchor the first and second layers of structural material to the insulating foam layer. The first and second layers of molded structural material extend into the grooves and under the groove shoulders to form a mechanical engagement between the insulating foam layer and the first and second layers of molded structural material.
