中文摘要 | 背景:國內建築物室內壁面或樓板常出現漏水、壁癌、與白華所導致居住環境健康上疑慮。目的:本文擬針對室外塗裝材料與日曬溫度對水泥質材料耐候性質的影響進行研究。方法:四種塗料(壓克力樹脂塗料,環氧樹脂塗料,無機水性塗料,和耐候漆)使用於砂漿進行試驗。分別進行三種加速劣化,如在烘箱在50和75攝氏溫度下,加速惡化的572小時。以鹽霧測試2000小時的加速惡化,與572小時的氙氣燈劣化,以討論每個塗裝材料的屬性。結果:由試驗結果表示,壓力強度在不同的塗裝材料劣化過程的變化不大。關於太陽模擬的氙氣燈劣化,顏色,光澤度明顯改變前200小時;經分類屬於不同的顏色變化。壓克力塗料具有最大的變化。雖然不同劣化溫度試樣的力學性能試驗顯示僅略有下降,但水的滲透性和氯離子擴散係數卻有較大的變化,主要受到水泥質材料微裂紋成長所影響。結論/實務應用:塗料雖於未劣化時有保護水泥質基材效果,但其耐候耐久性質仍受溫度加速劣化的影響而有變差現象。因此建議當未劣化時,以晴雨漆進行塗裝可達到保護水泥基材之效果。但若考量長時間日曬時,需考慮有相關隔熱措施,如於表面再加一層泡沫隔熱漆,可使水泥基材達到保護與耐候效果。 |
英文摘要 | Backgrounds: Building walls often appear leaking and health concerns in the living environment.Purposes: This research focuses on weathering resistance of painting material on mortar.Methods: Four kinds of painting materials (acrylics paint, epoxy resins paint, inorganic water-based paint, and all weather paint) were used on mortar. Three deterioration processes-accelerated deterioration of 572 hours in oven at 50 and 75 degree C, accelerated deterioration of 2000 h of mist testing, and 572 hours Xenon light deterioration-were employed to discuss the properties of each painting material.Results: Experimental results show that compressive is little change with different painting materials in deterioration processes. With regard to the deterioration in solar simulation, color and gloss significantly change before 200 hours; classification belongs to a distinct color change.Conclusions: The acrylic paint has greatest change. Although the temperature deterioration on the mechanics properties of specimens are slightly, but water permeability and chloride diffusion coefficients have larger. |
