Detailed Description
The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.
As shown in fig. 1-3, the utility model provides a processing structure for profiled sheet outer wall and roofing system seepage is a composite coating, includes sealed glue 6 of one deck, waterproof first coat 7 of one deck, waterproof floating coat 8 of one deck and the waterproof top coat 10 of one deck that sets gradually from inside to outside along the surface of wall profiled sheet panel 1.
The processing structure for the leakage of the outer wall of the profiled steel sheet and the roof system is arranged at the seam part of the profiled steel sheet, and the width of the composite coating is 100mm in the vertical direction of the seam part of the profiled steel sheet; the width of the composite coating is 200mm in the horizontal direction of the seam part of the profiled steel sheet.
A layer of fiber mesh cloth 9 is arranged between the waterproof middle coat 8 and the waterproof top coat 10 for preventing cracking.
The sealant 6 is a polyurethane sealant.
The waterproof base coat is HCA acrylic acid high-elasticity waterproof coating base coat.
The waterproof middle coating is HCA acrylic acid high-elasticity waterproof coating middle coating.
