AIRTIGHT PRESSURE SENSITIVE ADHESIVE TAPE FOR WATER PROOF OF BUILDING

摘要

PROBLEM TO BE SOLVED: To provide an airtight pressure sensitive adhesive tape for waterproofing a building which performs waterproofing and inhibits thermal emission for a long term by weather-stripping a gap between heat insulators and a gap between a pillar and an heat insulator. SOLUTION: In the pressure sensitive adhesive tape composed of a base fabric layer formed by fusing a coating layer made up of a thermoplastic resin film on one side or both sides of a woven cloth layer obtained by weaving a flat yarn made of a thermoplastic resin and an pressure sensitive adhesive layer formed by applying an pressure sensitive adhesive to one side of the above base fabric layer, this airtight pressure sensitive adhesive tape for waterproofing a building features that the thermoplastic resin film is a thermoplastic resin film containing both of a hindered phenol-based antioxidant and a phosphite-based antioxidant in an amount of 0.05-0.35 wt.% and the pressure sensitive adhesive layer is made of a pressure sensitive acrylic adhesive having a lamination adhesive strength of >=1,000 g/mm.
