EXTERIOR WALL TILE EXFOLIATION PREVENTION STRUCTURE, EXTERIOR WALL TILE EXFOLIATION PREVENTION METHOD, AND ALICYCLIC POLYAMINE USED THEREFOR

摘要

PROBLEM TO BE SOLVED: To provide an exterior wall tile exfoliation prevention structure and an exterior wall tile exfoliation prevention method, capable of preventing exfoliation of a tile affixed to a concrete outer coating of an architectural structure without impairing design of the tile, and to provide an alicyclic polyamine used therefor.;SOLUTION: An exterior wall tile exfoliation prevention structure is characterized in that an anchor pin is driven into an exterior wall tile surface or a joint, the anchor pin is fixed to a concrete skeleton, and a transparent primer layer is formed by applying an acrylic silicone resin primer to a head of the anchor pin, the exterior wall surface and the joint. A transparent reinforcement layer is formed by applying a polyurea resin coating containing non-yellowing isocyanate prepolymer, alicyclic polyamine, reinforcement short fiber, a light stabilizer and an ultraviolet absorber onto the transparent primer layer. A transparent protection layer is formed by applying an acrylic silicone resin coating containing a light stabilizer and an ultraviolet absorber onto the transparent reinforcement layer.;COPYRIGHT: (C)2014,JPO&INPIT
