纤维类幕墙保温材料用阻燃型防水透气膜的研制

Development of flame-retardant breathable waterproof membrane for fiber wall insulation materials

通过对防水透气剂的研究,并选用不燃的玻璃纤维布作为胎基材料,制备出了防水性能良好且具有阻燃效果的防水透气膜。该阻燃型防水透气膜在14.7 kPa水压作用2 h后测试背面无渗漏,水蒸气透过率可达1400 g/(m2·d),防风性能达2400 s/100ml,燃烧性能为A2级。

Waterproof and breathable reagent was researched in this paper, and a kind of waterproof and breathable membrane with good waterproof and noncombustible properties was prepared by choosing the noncombustible glass fabric as the base material. There was no seepage on the back of the membrane after it was tested 2 hours later under 14.7 kPa water pressure. The water vapor transmission was 1400 g/ （m2 d） , the windproof performance was 2400 s/100 ml and the combustion performance was class A2.
