摘要:	建築用布膜產品具高附加價值，為現今布膜產品發展之主要方向，具有良好透光性、高比強度、低潛變、自潔性、搭建快速等優點。本研究朝節能減碳之訴求進行研議，構想使膜結構建築內之空調用電降低，增進環保效益。選擇使用玻璃纖維梭織布為基布進行加工製作，三明治結構之方式於兩層玻璃纖維布間貼合微多孔PU，賦予整體布膜透濕防水性質。上下兩層玻璃纖維梭織布則負責主要之物理強度，並於最外層噴塗PTFE樹脂，達封裝效果與其基本自潔性能。 PTFE／玻璃纖維梭織布以70g/min二段式噴塗，240℃成形擁有本研究最佳疏水與界面附著性質，接觸角可達124°且持續10min無變化。相較30g/min之樣本初始接觸角提升50.06%，10sec即完全濕潤；相較50g/min之樣本初始接觸角上升6.05%，31sec即完全濕潤。噴塗重為24.7 g/m2。玻纖／微多孔PU／玻纖之三明治結構，以三刀式300μm複合加工具本研究最佳之透濕防水性能。水壓值為3080mmH2O，相較一刀式300μm提高約300.16%；透濕度為834.7 g/m2．24hrs，降低約25.41%。整體厚度平均約695μm；膜厚平均為120.54μm；平均整體布重為820.7g/m2；平均塗佈重為143.1g/m2，孔隙寬度分佈在20~60μm，平均為32.98 μm。透濕防水型玻璃纖維布膜，使用70g/min二段式噴塗，240℃成形之PTFE／玻璃纖維梭織布，並以三刀式300μm複合加工，具最佳透濕防水與疏水自潔性能。水壓值為3830 mmH2O，相較無噴塗PTFE之三刀式300μm複合三明治結構樣本提高約24.35%。透濕度降至495.1 g/m2．24hrs，減少40.69%。整體厚度平均約701μm；膜厚平均為150.07μm；孔隙寬度分佈在30~70μm，平均為50.61 μm。平均整體布重為845.1 g/m2；塗佈重與噴塗重之加總平均為167.5g/m2。 Membrane is a soft and flexible material, use a viscosity polymer coating on the outside or infiltrating the interface of textile. The architectural membrane has excellent value promote the development of this product. It’s characteristic include light transmittance、specific strength、low creep、self-clean、build fast. This study will work on the trend of energy and carbon reduces, decrease the air-conditioning electricity in membrane structure. This product was sandwich structure by glass fiber woven / micro-porous PU / glass fiber woven to obtain the property of water-vapor permeable and liquid-water impermeable. The glass fiber woven provide mechanical properties used PTFE to package it and to make self-clean. The PTFE / glass fiber woven spray with two-stage of 70g/min, heat treatment at 240℃ have optimal property of hydrophobic and interface adhesion. The contact angle is 124° and not changes after 10 min, increase 50.06% than sample under 30g/min spray rate, wetting on 10sec; increase 6.05% than sample of 50g/min,complete wetting on 31sec. The weight of spray is 24.7 g/m2 The glass fiber / micro-porous PU / glass sandwich structure composite which with three-stage-coating with 300μm have well water-vapor permeable and liquid-water impermeable. The pressure values is 3080 mmH2O, increase 300.16% than sample of 30g/min; the water-vapor permeable is 834.7 g/m2．24hrs, decrease 300.16%. The average totally thickness is 695μm; Thickness of micro-porous PU is 120.54μm. Totally weight is 820.7g/m2; weight of micro-porous PU is 143.1g/m2. Width of porous between of 20-60 um, average is 32.98 um. The water-vapor permeable and liquid-water impermeable membranes spray by twogstage of 70g/min, forming at 240℃ and composite which with three-stage-coating with 300μm have significant property in this paper. The pressure values is 3830mmH2O, increase 24.35% than composite by three-stage-coating with 300μm used glass fiber woven unsprayed PTFE. The water-vapor permeable is 495.1 g/m2．24hrs, decrease 40.68% than composite by three-stage-coating with 300μm used glass fiber woven unsprayed PTFE . The totally thickness is 701μm; Thickness of micro-porous PU is 150.07μm. Totally weight is 845.1g/m2; weight of micro-porous PU and PTFE is 167.5g/m2. Width of porous is about of 30-70 um, average is 50.61 um.
