Ultra-thin laminated sheet with molecular micro-vacuum adhesion and warp and weft textile matrix for mechanical memory recovery for light control on smooth translucent surfaces

Abstract

The present invention discloses a utility model relating to an ultra-thin laminated film (2) designed for reusable light control on translucent surfaces such as front and rear windshields, side windows or glass of all types of vehicles, and glazed architectural structures (windshields / glass / panes) (1). The invention solves the dual technical problem of loss of adhesion due to mechanical fatigue (creasing) after folding for storage, and premature delamination caused by thermal stress in vehicle windshields. The structural configuration comprises a microcellular elastomeric layer (3) based on PDMS or EVA with a thickness (d1) of less than 0.5 mm, provided with micro-vacuum cavities (5); and a warp-weft textile structural layer (7), forming a total thickness (d2) of less than 1.0 mm.Both layers are bonded together by a lamination interface (4) formed by an RTV (Room Temperature Vulcanizing) silicone adhesive, which acts as a thermoset anchor resistant to continuous sunlight exposure. The orthogonal arrangement of the textile matrix absorbs mechanical stress (11) during folding. When the product is unfolded, the tension network (12) of the fabric exerts a memory recovery force (13) that mechanically compels the elastomer to return to its absolute flatness. This flatness guarantees continuous nanometric proximity at the contact interface, activating Van der Waals intermolecular forces which, in synergy with the uncollapsed micro-cavities (6), configure a dual physical mechanism that ensures prolonged vacuum airtightness without requiring chemical adhesives.
