Description

TECHNICAL FIELD

[0001] The present application relates to building waterproofing engineering, in particular to a fire-retardant stainless steel foil waterproofing membrane and a preparation method thereof. BACKGROUND

[0002] With the popularization of photovoltaic power generation, the aging resistance, high temperature resistance and fire resistance of roofing waterproofing materials are strictly required due to the high temperature and fire hazards of photovoltaic panels. Currently available are high polymer waterproofing membranes, fluorocarbon film self-adhesive membranes and stainless steel foil butyl self-adhesive membranes. Among them, the stainless steel foil butyl self-adhesive membrane selects stainless steel foil as the exposed material, which has outstanding stain resistance, corrosion resistance, aging resistance, high surface hardness and complete fireproof surface, and is particularly suitable for waterproofing engineering with photovoltaic power stations.

[0003] However, the existing stainless steel foil butyl self-adhesive membrane and the stainless steel composite waterproofing membrane disclosed in the Chinese patent mostly directly hot-composite the waterproofing base material layer on the surface of the stainless steel foil, and some have a PET film adhered to the surface of the stainless steel foil, and then composite the waterproofing base material layer. The above conventional methods are prone to peeling of the stainless steel foil and the waterproofing base material layer due to low adhesion of the stainless steel surface, aging damage of the PET film and other problems in high temperature environment, thereby causing waterproofing failure.

[0004] In addition, the butyl self-adhesive membrane on the market currently uses uncrosslinked butyl rubber self-adhesive glue, which will also flow and cause cohesive failure of the adhesive interface in high temperature and vibration environment, thereby causing peeling and falling off of the waterproofing layer and the base layer. At the same time, it cannot avoid the fire hazard caused by local overheating of the surface stainless steel.

[0005] Finally, in photovoltaic power station engineering, photovoltaic panels absorb sunlight and transfer a large amount of heat to the underlying space, and traditional waterproofing materials have no heat insulation function, which will also adversely affect the indoor temperature. SUMMARY
