ROOT BARRIER SHEET MADE OF SYNTHETIC POLYMERS AND A METHOD OF APPLYING THE SHEET

摘要

PURPOSE: A root barrier sheet made of synthetic polymers and a method for applying the same are provided to exhibit high root barrier properties as well as waterproof characteristic. CONSTITUTION: A root barrier sheet made of synthetic polymers comprises as follows. An upper sheet layer(1) includes ethylene acrylic acid copolymer resin(EAA). An middle sheet layer(2) comprises 55-75wt% ethylene vinyl acetate(EVA) resin and 25-45wt% octane. A lower sheet layer(3) comprises 50-70wt% ethylene methacrylic acid(EMAA) copolymers and 30-50wt% oleic acid. The upper sheet layer, middle sheet layer, and lower sheet layer are laminated in turn. The upper sheet layer contains 0.1-10.0wt% antioxidant.
