摘要： The present invention provides a composite insulation material. The material includes a layer of an insulation, such as foam or fiberglass, and a paper layer. The paper layer is coated with a moisture vapor barrier, using a coating composition that includes a resin latex and a component having a crystalline platelet structure. Suitable resin latexes include poly(meth)acrylates, carboxylated or non-carboxylated butadiene-acrylonitrile, polystyrene, styrene-acrylonitrile, styrene-acrylonitrile-butadiene, styrene acrylates, styrene-butadiene, carboxylated styrene butadiene, polyvinyl chloride, polyvinyl acetate, waterborne polyurethanes, vinyl acrylics, polyvinylidene chloride, ethyl vinyl chloride, vinyl acetate- ethylene copolymers, and copolymers, terpolymers, and blends thereof. A suspending agent for the crystalline platelet component can be present, and is typically a hydrophilic polymer. The coating compositions can include wax, or can be essentially devoid of wax. A hydrophobic agent other than wax can optionally be added. The crystalline platelet structure can be unmodified, or modified to increase its hydrophobicity. The composite material can also be in the form of a foil/scrim/Kraft paper laminate, which can be combined with a layer of insulation if desired. The insulation materials can be used, for example, to insulate pipes and ductwork, or other aspects of buildings.
