Title:
SEALING FILM FOR BUILDING PROTECTION
Document Type and Number:
WIPO Patent Application WO2006079383
Kind Code:
A3
Abstract:
The invention relates to a sealing film for building protection, which is water-tight and has a high resistance to tearing and flexibility, comprising a single supporting layer (1) made of a tear-resistant and flexible supporting material and comprising a coating (2), which is applied to the supporting layer (1) on one or both sides, is applied in the form of an aqueous dispersion to the supporting layer (1), and is dried thereon. This coating (2), on the one hand, is provided with at least on chemical flameproofing agent and, on the other, has a considerable amount of nonflammable, solid inorganic fillers, particularly nonflammable inorganic fibers. Alternatively at least one supporting layer (1) made of a tear-resistant and flexible supporting material, namely a nonwoven, woven, knitted fabric or bonded fabric, which is open to diffusion by water vapor and which is based on glass fibers and/or acrylic fibers, and a film-like coating (2), which is inseparably joined to the supporting layer (1) are provided. The supporting material forming the supporting layer (1) is provided so that it is flame-resistant, and the film-like coating (2) comprises: a) 10 to 80 % by weight of a plasticized, bitumen-compatible PVC; b) 1 to 30 % by weight of a nitrile rubber or of an acrylic rubber; c) 1 to 10 % by weight of a flameproofing agent, and; d) 20 % by weight to 50 % by weight of a plasticizer based on polyadipate. In both cases, building material class B1 of DIN 4102 can be attained.
