    摘要: Multilayer films including thin film coating structures are provided that generate colors through certain reflective mechanisms. Both opaque and transparent applications are demonstrated. A coating of a thin metal layer provides a reflective surface on which one or more colors are generated, where the metal layer can control a general level of transparency of the overall multilayer film. Inclusion of one or more dielectric layers, adjustment of thicknesses thereof, and the number and order in which such dielectric layers appear in the multilayer film can be tailored to generate unique colors with unique properties.

    摘要: The present invention relates to the technical field of waterproof materials, and particularly to a high-strength wind-resistant skid-resistant waterproof underlayment. The high-strength wind-resistant skid-resistant waterproof underlayment comprises a first non-woven fabric layer, a first film layer, a first asphalt layer, a gridding cloth layer, a second asphalt layer, a second non-woven fabric layer, a second film layer and a third non-woven fabric layer laminated successively; the first film layer and the second film layer are waterproof elastic films respectively. The object of the present invention is to provide a high-strength wind-resistant skid-resistant waterproof underlayment. The waterproof underlayment formed by structures such as a first film layer and a second film layer and the like can be fixed through nails on a roof made of a wood structure, etc., and the construction is quick, convenient, and labor-saving, and the waterproofness is good.

    摘要: An object of the present invention is to provide a layered sheet having improved mechanical properties and excellent interlayer adhesion. The object can be fulfilled by a layered sheet formed by layering a modified-polyolefin layer (3), a copolymerized polyamide layer, (4), and a thermoplastic polyurethane-based resin layer (5) in this order on at least one surface of a cloth layered sheet (2) formed by layering a plurality of cloths comprised of thermoplastic resin strands or a layered sheet formed by layering a modified-polyolefin layer (3), a copolymerized polyamide layer, (4), and a polyamide-based resin layer (6) in this order on at least one surface of a cloth layered sheet (2) formed by layering a plurality of cloths comprised of thermoplastic resin strands.
