The invention includes a microbe-mitigating architectural barrier that includes a barrier forming material, and at least one biocide. The barrier forming material may be a bitumen product, an elastomeric polymer and combinations thereof. The microbe-mitigating architectural barrier may be formed by applying an emulsion composition directly to an architectural surface, or may be pre-formed and adhered or otherwise secured to the architectural surface in the form of a sheet or film.The invention also includes architectural assemblies and/or building envelopes that include the microbe-mitigating barrier. Related methods encompassed within the invention include a method of preparing an architectural barrier that includes: (a) preparing an emulsion that comprises a barrier forming material chosen from a bitumen product, an elastomeric polymer and combinations thereof, and at least one biocide, (b) applying the emulsion to at least one architectural surface, and (c) drying and/and or curing the emulsion to form a barrier.

It is an object of the present invention to provide a modified propylene resin containing very small amounts of low-crystalline and low-molecular-weight components. The present invention relates to a modified propylene resin characterized by satisfying the following requirements (1) to (4). (1) The melting point (Tm) measured with a differential scanning calorimeter (DSC) is 140° C. or higher. (2) The amount of grafts of ethylenic unsaturated bond-containing monomer after hot xylene washing is 0.1 to 5 percent by weight. (3) The amount of components soluble in o-dichlorobenzene at 70° C. is 1.5 percent by weight or less. (4) The intrinsic viscosity [η] is 0.1 to 4 dl/g.
摘要:
A laminate material formed of an elastomeric polymer sheet and a nonwoven fabric sheet. The sheets are passed through a niproll assembly during lamination, one of the niprolls having a series of embossing points protruding therefrom, and the other niproll being substantially flat. The embossing points press selective areas of the preferably molten polymer sheet into the fabric sheet, encapsulating the fabric fibers and bonding thereto. The resulting material has points of bonding where penetration has occurred and areas of nonpenetration, providing adherence of the two sheets while permitting independent movement of the fibers and elastic properties. Preferably, a release agent is added to the elastomeric polymer to reduce the possibility of the elastomer layer sticking to the nonwoven layer when the laminate is wound onto a supply roll.

THE DISCLOSURE INVOLVES A FORM OF PREFABRICATED STURCTURE SUCH AS COMMERCIAL OR INDUSTRIAL BUILDINGS, HOUSES OR ENCLOSURES EMPLOYING AN EXTERNAL SKIN BONDED TO AN INTERMEDIATE STRUCTURAL AND INSULATING FILLER WITH AN INNER SURFACE SKIN SIMILARLY BONDED TO THE FILLER MATERIAL. THE EXTERNAL SKINS ARE PREFERABLY RESIN BONDED GLASS FIBER AND THE INTERMEDIATE FILLER COMPOSES A RANDOM HONEYCOMB STRUCTURE MADE OF CELLULOSIC MATERIAL, SUCH AS INDIVIDUAL PIECES OR PAPER OF RANDOM SIZE EACH RIGIDIFIED AND BONDED TO ADJACENT PIECES BY A RESINOUS BINDER WHICH IS COMPATIBLE WITH THE BINDER OF THE SKINS. THE STRUCTURE IS SHOWN IN CONTINUOUS PANELS AND ACTUALLY THREE DIMENSIONAL STRUCTURE CONFIGURATIONS AS WELL AS DISCRETE STRUCTURAL ELEMENTS WHICH MAY BE USED TO REPLACE COMPARABLE STRUCTURAL ELEMENTS NORMALLY MADE OF WOOD. DISCLOSED ALSO ARE PROCESSES FOR CONTINUOUS MANUFACTURE OF STURCTURES EMPLOYING THE CONCEPT OF THIS INVENTION EITHER IN THE FACTORY OR ON SITE. THE SAME BASIC STRUCTURE IS SHOWN IN VARIOUS CONFIGURATIONS. ILLUSTRATED ARE A NUMBER OF PANEL SECTIONS EMPLOYING THE SAME STRUCTURE ARRANGEMENT BUT DIFFERENT FILLER OO21ING DENSITY WHEREBY THE LOAD BEARING STRENGTH OF THE PANEL MAY BE CONTROLLED AND ITS INSULATING PROPERTIES VARIED AS WELL. STRUCTURAL STRENGTH CAN ALSO BE VARIED BY CHANGING THE DIMENSIONS AND CONCENTRATIONS OF RESIN/FIBERGLAS OF EITHER OR BOTH EXTERNAL SKIN SURFACES. DISCLOSED ALSO ARE INDIVIDUAL STRUCTURAL ELEMENTS PRODUCED FROM WASTE PAPER MATERIAL AND RESIN BONDED SKINS.
